Description

Technical Field

[0001] This invention relates to the field of functional home furnishings and health and wellness materials, specifically to an energy-free far-infrared antibacterial and deodorizing health-preserving pad and its preparation method. Background Technology

[0002] With the increasing health awareness and consumption upgrade among residents, people's demand for home furnishings has shifted from basic comfort and cushioning functions to a combination of functions such as health care, antibacterial properties, environmental protection, and wellness. As home furnishing products that come into close contact with the human body for extended periods, the hygiene and functional characteristics of mattresses, seat cushions, and other similar products directly affect the health and comfort of users.

[0003] However, existing traditional bed and seat cushions are typically made of ordinary sponge, fabric, or simple fillings, offering only basic physical support. Over long-term use, these cushions easily absorb sweat, dander, and other secretions, becoming breeding grounds for bacteria and mites, leading to unpleasant odors and even skin allergies and respiratory discomfort. They completely fail to meet modern consumers' needs for daily health and a clean home environment. In recent years, some health mats claiming far-infrared and antibacterial functions have appeared on the market, but their functions mostly rely on external power for heating or activation. This not only leads to high energy consumption, limited usage scenarios, and safety hazards, but also results in functional layers that often use chemical agents or simple functional powders directly added, leading to poor efficacy persistence, high risk of chemical residues, and limited functionality without synergistic effects. Furthermore, these products often use industrial adhesives during molding, making it difficult to meet environmental and skin contact safety standards suitable for mothers and infants.

[0004] Therefore, how to provide a health and wellness pad that requires no external power source, can spontaneously and continuously exert multiple effects such as far-infrared health care, efficient antibacterial, purification and deodorization in all weather conditions, and is made entirely of food-grade safe materials, environmentally friendly and non-irritating, as well as its preparation method, has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an energy-saving far-infrared antibacterial and deodorizing health-preserving pad and its preparation method.

[0006] To achieve the above objectives, the present invention provides the following technical solution: This application provides a method for preparing an energy-free far-infrared antibacterial and deodorizing health-preserving liner, comprising the following steps: Provide basic functional powders, which include natural mineral powders that can spontaneously release far-infrared rays and negative oxygen ions; The basic functional powder is surface-activated using a composite activation solution to obtain activated functional powder; the composite activation solution is composed of antibacterial metal ions, organic acids, and peroxides. The activated functional powder is mixed with natural herbal powder to obtain a composite functional powder; The composite functional powder is mixed with a binder system to form a paste, and the paste is molded onto a base fabric and dried to obtain the health-preserving liner. The binder system contains natural high-molecular polysaccharides and edible gums.

[0007] Preferably, the natural mineral powder is a mixture of hexagonal stone powder and tourmaline powder, and the mesh size of the natural mineral powder is not less than 1200 mesh.

[0008] Preferably, the composite activation solution is a mixed aqueous solution containing 60 ppm silver ions, 0.2% citric acid, and 2% hydrogen peroxide; wherein the antibacterial metal ion is silver ions, the organic acid is citric acid, and the peroxide is hydrogen peroxide.

[0009] Preferably, the surface activation treatment is carried out by spraying the composite activation solution evenly onto the basic functional powder through atomization spraying, followed by 60 minutes of static activation and then low-temperature drying.

[0010] Preferably, the natural herbal powder is a compound Chinese herbal medicine powder composed of patchouli, clove, costus root, mugwort, peppermint, atractylodes, dried plum, angelica, and eupatorium, and the mesh size of the natural herbal powder is not less than 325 mesh.

[0011] Preferably, when the activated functional powder is mixed with the natural herbal powder, the mass ratio of the activated functional powder to the natural herbal powder is 7:3.

[0012] Preferably, the natural high molecular weight polysaccharide is chitosan, and the mass fraction of chitosan in the adhesive system is 5%.

[0013] A non-energy-consuming far-infrared antibacterial and deodorizing health-preserving pad is prepared by the above-mentioned method. The health-preserving pad has a porous structure and continuously and spontaneously emits far-infrared rays in the 8-15μm band and releases negative oxygen ions.

[0014] Preferably, the health-preserving pad has an antibacterial rate of not less than 99% against Escherichia coli and Staphylococcus aureus, and a far-infrared emissivity of not less than 92%.

[0015] A composite functional powder, used to prepare the above-mentioned health-preserving pad, the composite functional powder comprising: The natural mineral powder is surface activated by a composite activation solution, wherein the natural mineral powder comprises hexagonal stone powder and tourmaline powder, and the composite activation solution is an aqueous solution containing silver ions, citric acid and hydrogen peroxide; The natural herbal powder is mixed with the activated natural mineral powder, wherein the natural herbal powder is a mixture of agastache, clove, costus root, mugwort, peppermint, atractylodes, dried plum, angelica, and eupatorium.

[0016] Compared with the prior art, this application has the following beneficial effects: The preparation method provided by this invention systematically solves the technical problems in this field through an integrated process route of pre-activation of basic mineral powder, inorganic / organic functional coupling, and food-grade green molding. The method first uses a specific ternary composite activation solution containing silver ions, citric acid, and hydrogen peroxide to perform atomized spraying and static activation treatment on natural minerals such as hexagonalite and tourmaline. This step, through a multi-synergistic mechanism of organic acid stabilization, deep modification of peroxide, and simultaneous loading of antibacterial metal ions, not only significantly activates the physicochemical active sites on the mineral surface, increasing the far-infrared emission efficiency of the final product by more than 15%, but also stably loads silver ions onto the powder surface for a long time, realizing the pre-antibacterialization of functional powders and overcoming the problems of easy loss of antibacterial components and short-term efficacy caused by traditional direct mixing. Building upon this foundation, activated mineral powders were organically fused with specific compound herbal powders containing herbs such as patchouli and mugwort at an optimal mass ratio of 7:3. This successfully constructed a triple antibacterial system combining mineral physical antibacterial, ionic chemical antibacterial, and herbal natural antibacterial properties. It also employed a multi-dimensional deodorization and purification mechanism that integrates physical adsorption, chemical decomposition, and herbal aroma masking. This resulted in an antibacterial rate and odor removal rate exceeding 90%, achieving synergistic effects among multiple functions rather than simple additives. Finally, a green binding system using 5% chitosan compounded with edible gum was employed to completely... By abandoning industrial adhesives, the product achieves a level of safety suitable for mothers and infants, ensuring that the powder is firmly bonded, does not fall off, forms a porous structure with good permeability, and does not hinder the release of functions. The entire process is simple and environmentally friendly, and low-temperature control throughout ensures the stability of each active ingredient. The resulting pad product can emit 8-15μm far-infrared life light waves and release negative oxygen ions continuously around the clock without any energy. It has a compound effect of highly effective antibacterial, deodorizing and purifying, and herbal health care, perfectly achieving the unity of zero energy consumption, multi-functional integration and high safety.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Furthermore, in this invention, an element referred to as fixed to or disposed on another element may be directly disposed on the other element, or there may be an intermediate element. When an element is considered to be connected to another element, it may be directly connected to the other element, or there may be an intermediate element present simultaneously. The terms vertical, horizontal, left, right, and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0020] Example 1 See Figure 1 This application provides a method for preparing an energy-free far-infrared antibacterial and deodorizing health-preserving liner, comprising the following steps S1-S4: Step S1. Provide basic functional powder, which includes natural mineral powder that can spontaneously release far-infrared rays and negative oxygen ions.

[0021] In this embodiment, natural hexagonal stone and tourmaline are selected as raw materials for natural mineral powder. Hexagonal stone can continuously emit far-infrared life light waves in the 8-14μm band and spontaneously release negative oxygen ions, while also having the effects of adsorbing harmful gases and inhibiting bacteria. Tourmaline has permanent self-electrode characteristics, and can continuously release far-infrared rays and negative oxygen ions without any external energy, which can destroy the living environment of bacteria and microorganisms and inhibit the reproduction of mites and bacteria. Hexagonal stone and tourmaline are ground and sieved separately by ball mill to obtain ultrafine powder, which is then put into a conical mixer at a mass ratio of 1:1 and thoroughly mixed to obtain composite mineral powder, which is used as the basic functional powder. By selecting natural minerals that can spontaneously release far-infrared rays and negative oxygen ions as functional base materials, the product can achieve passive health care functions under zero energy consumption conditions from the source, completely eliminating the dependence of traditional functional health care pads on external power supply, heating or light.

[0022] Step S2. The basic functional powder is surface activated using a composite activation solution to obtain activated functional powder; the composite activation solution is composed of antibacterial metal ions, organic acids and peroxides.

[0023] In this embodiment, silver ions are selected as the antibacterial metal ions, citric acid as the organic acid, and hydrogen peroxide as the peroxide. During preparation, a measured amount of deionized water is added to a clean mixing tank, stirring is started, and the silver ion preparation, food-grade citric acid, and hydrogen peroxide solution are added sequentially and precisely. Stirring continues until completely dissolved and evenly mixed, resulting in a composite spray solution containing 60 ppm silver ions, 0.2% citric acid, and 2% hydrogen peroxide. Silver ions possess highly efficient and broad-spectrum antibacterial capabilities, capable of killing Escherichia coli, Staphylococcus aureus, and Candida albicans by disrupting bacterial cell membranes, interfering with enzyme systems, and inhibiting DNA replication. It can inhibit common pathogens and catalyze the decomposition of hydrogen peroxide, enhancing the activation effect and achieving long-lasting antibacterial effect. Citric acid is used to adjust the pH value of the solution, improve the stability of silver ions and hydrogen peroxide, promote the surface activation of mineral powder, enhance the loading capacity of functional components, and also have the effects of mild antibacterial and deodorizing. Hydrogen peroxide has strong oxidizing properties and can quickly kill microorganisms on the surface of powder. After decomposition, it only produces water and oxygen, without any chemical residue. The specific operation of surface activation treatment is as follows: the composite mineral powder is transferred to a horizontal mixer equipped with a high-speed flying knife and atomizing spray system, and the mixer is started for stirring. While stirring, simultaneously activate the atomizing spray system to evenly spray the prepared composite activation solution onto the constantly churning powder surface in a mist form. The spray volume should be sufficient to fully wet the powder without any liquid seepage. Atomizing spraying ensures thorough and uniform contact between the activation solution and the mineral powder, preventing localized over-solution that could lead to powder agglomeration and affect subsequent molding. After spraying, turn off the spray system and keep the mixing chamber closed, allowing the powder to undergo 60 minutes of static activation under continuous stirring to ensure the activation components fully react with the mineral powder surface. During this process, the weakly acidic environment created by citric acid simultaneously stabilizes the silver ions. The activity of the silver ions and the strong oxidizing properties of hydrogen peroxide allow for deep oxidation modification of the mineral powder surface, exposing more high-energy surface sites. Silver ions are then effectively and long-lastingly loaded onto these newly formed sites, completing activation, modification, and pre-antibacterial treatment in one step. After activation, the powder is removed and transferred to a hot air circulating drying oven, where it is dried at a low temperature of 45°C until the moisture content is below 1%. If slight agglomeration occurs, it is broken up to obtain the activated functional powder. The entire process of low-temperature treatment aims to protect the stability of the subsequently introduced herbal active ingredients and silver ions, and to prevent the decomposition and failure of heat-sensitive functional substances.

[0024] Step S3. Mix the activated functional powder with the natural herbal powder to obtain a composite functional powder.

[0025] In this embodiment, the natural herbal powder is a compound Chinese herbal powder composed of patchouli, clove, costus root, mugwort, peppermint, atractylodes, dried plum, angelica, and eupatorium. In this compound, patchouli, atractylodes, and eupatorium can aromatically clear turbidity, remove dampness and odor, inhibit the growth of mold and bacteria, and freshen the air; clove and mugwort have natural herbal antibacterial and insect-repellent effects, which can soothe the skin and reduce mite growth; costus root and angelica regulate qi and blood circulation, and have a long-lasting fragrance, enhancing the health-preserving and soothing effect; peppermint is cool and soothing, refreshing and deodorizing, relieving discomfort from prolonged sitting or lying down; dried plum has astringent and antibacterial properties, helping to prolong the duration of the herbal effects; the nine herbs combined achieve a triple effect of natural antibacterial, aromatic deodorizing, and health-preserving and soothing; the above-mentioned activated functional powder... The powder and compound Chinese herbal medicine powder are added together in a 7:3 mass ratio into a three-dimensional motion mixer and mixed thoroughly for 30 minutes to obtain a homogeneous composite functional powder that integrates far-infrared emission, antibacterial, deodorizing, and health-preserving properties. This coupling is not a simple mixing, but rather utilizes the huge specific surface area and porous structure of ultrafine mineral powder as a slow-release carrier of natural herbal active aroma, achieving a long-lasting and slow release of herbal fragrance. The far-infrared and negative oxygen ion functions and silver ion antibacterial functions of the activated mineral powder complement the antibacterial, deodorizing, and health-preserving effects of the natural herbal powder, jointly constructing a triple antibacterial system of physical antibacterial, chemical antibacterial, and herbal antibacterial, as well as a multi-stage purification mechanism of adsorption deodorization, decomposition deodorization, and aromatic deodorization.

[0026] Step S4. The composite functional powder is mixed with the bonding system to form a paste, and the paste is molded onto the base fabric and dried to obtain the health-preserving pad. The bonding system contains natural high molecular weight polysaccharides and edible gums.

[0027] In this embodiment, chitosan is selected as the natural high-molecular-weight polysaccharide, and food-grade gelatin is selected as the edible adhesive. When preparing the adhesive solution, deionized water is added to the reactor and heated to 40°C. Chitosan powder is slowly added while stirring until its mass fraction reaches 5%. Stirring is continued until it is completely dissolved, resulting in a clear and viscous chitosan solution. Chitosan has good film-forming, adhesive, and antibacterial properties, and excellent biocompatibility. It can naturally form a porous network framework during the drying and film-forming process, firmly encapsulating and anchoring the functional powder particles. This effectively prevents the powder from falling off and ensures the permeability of the internal structure of the liner, allowing far-infrared rays, negative oxygen ions, and herbal aromas to be released smoothly and without obstruction. The positive charge carried by chitosan itself also has an auxiliary antibacterial effect. Then, food-grade gelatin accounting for 0.5% of the total mass of the chitosan solution is added to the chitosan solution and stirred at a constant temperature until completely blended, resulting in an environmentally friendly adhesive solution. The introduction of edible adhesive can further enhance the bonding strength, flexibility, and durability of the padding, without any harmful chemical additives. The composite functional powder and the prepared adhesive liquid are added to a vacuum mixer at a mass ratio of 100:40. Under negative pressure, the mixture is stirred and degassed to form a uniform, viscous paste. The paste is then evenly coated onto a pre-laid, breathable cotton base fabric using a coating machine. The coating thickness is controlled by a scraper to ensure a smooth surface. The coated base fabric is then fed into a multi-layer mesh belt dryer and subjected to gradient low-temperature drying and shaping under circulating hot air at 50°C. After drying, the fabric is allowed to cool naturally and then moderately compacted by pressure rollers to make the structure dense and stable. Finally, it is cut and trimmed to the preset dimensions to obtain the finished health padding. For seat pads, the coating thickness can be controlled to 2mm, and the base fabric can be replaced with a dotted fabric with anti-slip properties to meet the special requirements of thinness and flexibility for seat pads.

[0028] In a preferred embodiment, the natural mineral powder is a mixture of hexagonal stone powder and tourmaline powder, and the mesh size of the natural mineral powder is not less than 1200 mesh.

[0029] In this embodiment, natural hexagonal stone and tourmaline are ground separately using a ball mill, then sieved to obtain 1200-mesh ultrafine powder, and then mixed evenly at a 1:1 mass ratio. Hexagonal stone can continuously emit far-infrared life light waves in the 8-14μm band, spontaneously release negative oxygen ions, and also has the effects of adsorbing harmful gases and inhibiting bacteria. Tourmaline has permanent self-electrode characteristics, and can continuously release far-infrared rays and negative oxygen ions without any external energy, which can destroy the living environment of bacteria and microorganisms and inhibit the reproduction of mites and bacteria. The combination of the two can achieve synergistic effect of mineral functions, enhance far-infrared emission and antibacterial purification effects. Controlling the powder fineness to above 1200 mesh is to greatly increase the specific surface area of ​​the functional powder, which is conducive to the full and uniform contact between the activation solution and the powder during subsequent activation treatment, making the activation reaction more thorough, and also conducive to the efficient release of far-infrared rays and negative oxygen ions.

[0030] In a preferred embodiment, the composite activation solution is specifically a mixed aqueous solution containing 60 ppm silver ions, 0.2% citric acid, and 2% hydrogen peroxide; wherein the antibacterial metal ion is silver ions, the organic acid is citric acid, and the peroxide is hydrogen peroxide.

[0031] In this embodiment, a measured amount of deionized water is added to a clean mixing tank, stirring is started, and silver ion preparation, food-grade citric acid, and hydrogen peroxide solution are added sequentially and precisely. Stirring continues until completely dissolved and mixed evenly, so that the concentration of silver ions in the solution is 60 ppm, the mass fraction of citric acid is 0.2%, and the mass fraction of hydrogen peroxide is 2%. Silver ions provide a highly efficient, broad-spectrum, and long-lasting antibacterial core, which can kill common pathogens by destroying bacterial cell membranes, interfering with enzyme systems, and DNA replication, while catalyzing the decomposition of hydrogen peroxide to enhance the activation effect. Citric acid ensures a weakly acidic environment in the solution system, under which the activity of silver ions and the stability of hydrogen peroxide are simultaneously guaranteed, and it can promote the surface activation of mineral powders and enhance the loading capacity of functional components. Hydrogen peroxide plays a pretreatment role in deep oxidation modification and instantaneous sterilization, and its decomposition products are only water and oxygen, with no chemical residues. The three components have the best synergistic effect in this ratio, which can achieve the simultaneous completion of activation, modification, and antibacterial loading.

[0032] In a preferred embodiment, the surface activation treatment is carried out by spraying the composite activation solution evenly onto the basic functional powder through atomization spraying, followed by 60 minutes of static activation and then low-temperature drying.

[0033] In this embodiment, the composite mineral powder is transferred to a horizontal mixer equipped with a high-speed flying knife and an atomizing spray system. The mixer is started for stirring, and the atomizing spray system is turned on simultaneously to spray the composite activation solution evenly onto the constantly churning powder surface in a mist. The spray volume is such that the powder is fully wetted without any liquid seepage. The atomizing spray method allows the activation solution to contact the powder in the form of tiny droplets, ensuring uniform activation and avoiding excessive local solution that could cause powder agglomeration and affect subsequent molding. After spraying, the spray system is turned off, and the mixer is kept closed, allowing the powder to stand for 60 minutes under continuous stirring. The 60-minute standing time is to ensure that the activated components and the surface of the mineral powder have sufficient time to undergo a full chemical reaction, allowing the deep oxidation modification of hydrogen peroxide under the citric acid stabilized system and the silver ion loading process to be completely completed. After activation, the powder is removed and transferred to a hot air circulating drying oven, where it is dried at a low temperature of 45°C until the moisture content is below 1%. The low temperature control throughout the process aims to protect the stability of the subsequently introduced herbal active ingredients and silver ions from damage.

[0034] In a preferred embodiment, the natural herbal powder is a compound Chinese herbal medicine powder composed of patchouli, clove, costus root, mugwort, peppermint, atractylodes, dried plum, angelica, and eupatorium, and the mesh size of the natural herbal powder is not less than 325 mesh.

[0035] In this embodiment, nine kinds of Chinese herbal medicine slices, namely, patchouli, clove, costus root, mugwort, peppermint, atractylodes, dried plum, angelica, and eupatorium, are mixed in equal mass ratios, ground in a low-temperature ultrafine pulverizer, and sieved to obtain an ultrafine compound Chinese herbal medicine powder of 325 mesh. This powder is then sealed, protected from light, and dried for later use. In this compound, patchouli, atractylodes, and eupatorium can aromatically dispel turbidity, remove dampness and odor, inhibit the growth of mold and bacteria, and freshen the air; clove and mugwort have natural herbal antibacterial and insect-repellent effects, which can soothe the skin and reduce the growth of mites; costus root and... Angelica dahurica regulates qi and unblocks meridians, with a long-lasting fragrance, enhancing its health-preserving and soothing effects; peppermint is cool, soothing, and deodorizing, relieving discomfort from prolonged sitting or lying down; dried plum has astringent and antibacterial properties, helping to prolong the duration of herbal efficacy; the combination of these nine herbs complements the far-infrared and negative oxygen ion functions and silver ion antibacterial function of the activated mineral powder, jointly constructing a multi-layered antibacterial and deodorizing system; controlling the fineness of the herbal powder to above 325 mesh facilitates the full release of active ingredients and uniform mixing with the mineral powder.

[0036] In a preferred embodiment, when the activated functional powder is mixed with the natural herbal powder, the mass ratio of the activated functional powder to the natural herbal powder is 7:3.

[0037] In this embodiment, the activated functional powder and the composite herbal powder are added together in a three-dimensional motion mixer at a mass ratio of 7:3 and mixed thoroughly for 30 minutes to obtain a homogeneous composite functional powder. The 7:3 ratio maximizes the synergistic health benefits of herbs while ensuring the powerful core functions of far-infrared emission, negative oxygen ion release, and silver ion antibacterial properties. At the same time, the mixed powder at this ratio has good flowability and molding processability, and can be uniformly mixed with the adhesive to form a paste-like material, ensuring the smooth progress of subsequent coating processes and the stability of product quality.

[0038] In a preferred embodiment, the natural polymeric polysaccharide is chitosan, and the mass fraction of chitosan in the adhesive system is 5%.

[0039] In this embodiment, deionized water is added to the reactor and heated to 40°C. Chitosan powder is slowly added while stirring until its mass fraction reaches 5%, and stirring continues until completely dissolved, resulting in a clear and viscous chitosan solution. Chitosan, as a natural high-molecular-weight polysaccharide, has excellent film-forming, adhesive, and antibacterial properties, and excellent biocompatibility. The 5% mass fraction is an optimized value after screening. If the concentration is lower than this, the viscosity of the adhesive solution is too low, which cannot effectively bind the functional powder and easily leads to powder detachment. If the concentration is higher than this, the adhesive solution is too viscous, which is not conducive to uniform mixing with the powder and subsequent coating processing. At the same time, the film layer formed after drying may be too dense, hindering the release of far-infrared rays and negative oxygen ions. At a concentration of 5%, chitosan can naturally form a porous network framework with good permeability during the drying and film-forming process, which firmly encapsulates and anchors the functional powder particles, effectively preventing powder detachment and ensuring the smooth release of functional substances.

[0040] On the other hand, this application provides an energy-free far-infrared antibacterial and deodorizing health-preserving pad, which is prepared by the above-mentioned preparation method; the health-preserving pad has a porous structure and continuously and spontaneously emits far-infrared rays in the 8-15μm band and releases negative oxygen ions.

[0041] Specifically, the porous structure of the pad is naturally formed during the drying and film-forming process by a bonding system composed of chitosan and edible gum. This structure ensures both the firm bonding of the functional powders and prevents them from falling off, while also ensuring the permeability of the pad's interior, allowing for the release of far-infrared rays, negative oxygen ions, and herbal aromas. Because it uses hexagonal stone and tourmaline, which spontaneously release far-infrared rays and negative oxygen ions, as the core functional materials, the pad requires no external power source, light, or heating to continuously provide far-infrared health benefits and air purification in all weather conditions. The emitted 8-15μm band far-infrared rays are highly compatible with the vibrational frequency of human cell molecules, promoting subcutaneous blood circulation, improving metabolism, relieving physical fatigue, and achieving daily passive health maintenance.

[0042] As a preferred embodiment, the health-preserving pad has an antibacterial rate of not less than 99% against Escherichia coli and Staphylococcus aureus, and a far-infrared emissivity of not less than 92%.

[0043] Specifically: Testing of the pads prepared in the above embodiments, according to relevant standards, shows that the far-infrared normal emissivity of the product in the 8-15μm wavelength band reaches 93%, meeting the requirement of not less than 92%. According to the shaking flask method, the product's antibacterial rate against Escherichia coli and Staphylococcus aureus is greater than 99%, meeting the requirement of not less than 99%. Furthermore, using an air negative ion detector at a distance of 5cm from the pad surface, the negative oxygen ion generation reaches 850 ions / cm³. In a 1m³ experimental chamber, after 24 hours of placing the pad sample in, the ammonia removal rate was 92%, and the methanethiol removal rate was 90%. The achievement of these properties is attributed to the deep treatment of the mineral powder by the ternary composite activation system of silver ions, citric acid, and hydrogen peroxide, which allows silver ions to be firmly and persistently loaded onto the surface of the mineral powder, achieving long-lasting antibacterial effects. Simultaneously, the synergistic coupling of nine kinds of traditional Chinese medicine powder with the activated mineral powder constructs a physical, chemical, and herbal triple antibacterial and deodorizing mechanism, optimizing the product's overall performance.

[0044] Furthermore, this application provides a composite functional powder for preparing the aforementioned health-promoting pad, the composite functional powder comprising: The natural mineral powder is surface-activated by a composite activation solution, wherein the natural mineral powder comprises hexagonal stone powder and tourmaline powder, and the composite activation solution is an aqueous solution containing silver ions, citric acid and hydrogen peroxide; and the natural herbal powder is mixed with the activated natural mineral powder, wherein the natural herbal powder is a mixture of agastache, clove, costus root, artemisia, peppermint, atractylodes, dried plum, angelica and eupatorium.

[0045] In this embodiment, the composite functional powder comprises two components: one is a natural mineral powder surface-activated by a composite activation solution, which includes hexagonal stone powder and tourmaline powder, and the composite activation solution is an aqueous solution containing silver ions, citric acid and hydrogen peroxide; the other is a natural herbal powder mixed with the activated natural mineral powder, which is a mixture of agastache, clove, costus root, artemisia argyi, peppermint, atractylodes lancea, dried plum, angelica dahurica and eupatorium fortunei. In one specific embodiment, the composite functional powder is obtained as follows: First, 1200-mesh hexagonal stone powder and tourmaline powder are mixed in a 1:1 ratio to form the basic functional powder. Then, a composite activation solution containing 60 ppm silver ions, 0.2% citric acid, and 2% hydrogen peroxide is used for atomization spraying and 60-minute static activation. After drying at 45°C, activated functional powder is obtained. Next, the activated functional powder is mixed evenly with 325-mesh nine-herb compound powder at a mass ratio of 7:3. This composite functional powder integrates the far-infrared and negative oxygen ion functions of inorganic minerals, the broad-spectrum antibacterial function of silver ions, and the natural antibacterial, deodorizing, and health-preserving functions of traditional Chinese medicine. It is a key intermediate product constituting the core function of the health-preserving pad of this invention, and it can itself be used as an independent composite functional material in the preparation of other healthy household products.

[0046] Example 2 The mattress pad product prepared using the method of Example 2 of this invention can be laid between a household mattress and a bed sheet, or used directly as a replacement for a traditional mattress. The mattress pad is 3mm thick and its size can be cut according to the specifications of a household double bed or single bed.

[0047] In daily use, users only need to lie down normally, without any electricity, heating or light exposure; according to tests, the far-infrared emissivity of the pad reaches 93% in the 8-15μm wavelength band, and the negative oxygen ion generation reaches 850 ions / cm³, which can spontaneously act on the human body all day long, promote blood circulation in subcutaneous capillaries, accelerate metabolism, and relieve physical fatigue.

[0048] To verify the synergistic effect of the combination of hexagonal stone and tourmaline, the applicant prepared Comparative Example 1, which used only hexagonal stone, and Comparative Example 2, which used only tourmaline, for comparative testing. The results showed that the far-infrared emissivity of Comparative Example 1 was only 82%, and the amount of negative oxygen ions generated was 510 / cm³. The far-infrared emissivity of Comparative Example 2 was only 80%, and the amount of negative oxygen ions generated was 560 / cm³. Moreover, its antibacterial rate was only 96% and 95%, respectively, which was significantly lower than the 99.9% or more of Example 1. This indicates that hexagonal stone and tourmaline are not simply functionally superimposed. The two complement each other in the far-infrared emission peak position. The spontaneous electrode effect of tourmaline can form a continuous electric field at the microscale, which can excite the far-infrared active vibration in the hexagonal stone lattice and enhance the efficiency of water molecule ionization in the air to generate negative oxygen ions. This makes the far-infrared emissivity and negative oxygen ion release of the combined product far exceed the simple average value of the sum of the individual minerals.

[0049] Regarding antibacterial and deodorizing properties, prolonged bed rest can easily lead to the growth of bacteria and odors. The antibacterial rate of the mattress liner of this invention is greater than 99.9% against both Escherichia coli and Staphylococcus aureus, and the antibacterial durability remains above 99% for 28 days, with an ammonia removal rate of 92%. To verify the synergistic effect of the ternary composite activation system, the applicant set up Comparative Example 3 (unactivated), Comparative Example 4 (treated only with silver ion solution), and Comparative Example 5 (treated only with hydrogen peroxide solution). Among them, Comparative Example 3 had the lowest performance in all aspects, with a far-infrared emissivity of only 71%, an antibacterial rate of less than 75%, and a significant decrease in antibacterial durability to 45% after 28 days, indicating that the active sites on the surface of the unactivated mineral powder were in a dormant state, and the functional components could not be effectively loaded. Although the antibacterial rate of Comparative Example 4 increased to 90% and The silver ion emissivity was 88%, but the far-infrared emissivity was only 73%, indicating that single silver ion treatment could only achieve simple adhesion of antibacterial components and could not deeply modify the mineral surface; the far-infrared emissivity of Comparative Example 5 was only 75%, and the antibacterial durability dropped to 40% after 28 days, indicating that although hydrogen peroxide could oxidize and clean the powder surface, it lacked long-term loading of antibacterial components; the present invention constructs a weakly acidic and stable environment by using citric acid, which, under the premise of ensuring the activity of silver ions and the hydrogen peroxide oxidation modification effect, enables silver ions to be efficiently and firmly loaded on the newly formed high-energy sites exposed by hydrogen peroxide, thereby completing surface activation, deep modification, and long-term antibacterial loading in one step, achieving the optimal effect of far-infrared emissivity of 93%, antibacterial rate of over 99.9%, and durability of over 99% after 28 days.

[0050] Regarding odor removal, to verify the synergistic effect of the coupling of traditional Chinese medicine, the applicant set up a comparative example 6 without adding traditional Chinese medicine and a comparative example 7 with only Artemisia argyi added. The ammonia removal rate of comparative example 6 was only 65%, while that of comparative example 7 was increased to 78%, but it was still significantly lower than the 92% of the nine-ingredient compound of this invention. This indicates that the nine traditional Chinese medicines, through the synergistic effect of aromatic purification by patchouli, Atractylodes lancea, and Eupatorium fortunei, antibacterial and insecticidal effects by clove and Artemisia argyi, cooling and soothing effects by peppermint, and astringent and consolidating effects by Prunus mume to prolong the duration of efficacy, form a full-chain odor removal mechanism of adsorption, decomposition, and masking with the physical adsorption and chemical decomposition of activated minerals. The product is made of chitosan compound edible glue, and the skin irritation test showed no irritation, so it can be used safely by the elderly, children, and people with sensitive skin. In contrast, comparative example 8, which uses ordinary polyurethane adhesive, showed slight skin irritation.

[0051] Example 3 The seat cushion product prepared by the method of Example 3 of the present invention is laid on the surface of an office chair. The seat cushion has a coating thickness of 2mm, is thin and flexible, and the base fabric is a non-slip dotted fabric to ensure that it is not easy to slip during use.

[0052] Office workers often experience poor blood circulation in their hips and lower back due to prolonged sitting, leading to fatigue and discomfort. This invention's seat cushion continuously emits far-infrared rays even without an energy source, with an emissivity of 93%. This promotes local blood circulation and relieves muscle stiffness and soreness caused by prolonged sitting. The mint from the nine Chinese herbal ingredients releases a cooling and soothing aroma, helping to refresh the mind; the costus root and angelica root regulate qi and blood circulation, synergistically enhancing office comfort. As mentioned earlier, while Comparative Example 6, which does not contain Chinese herbal ingredients, has a similar far-infrared emissivity and negative ion generation as Example 1, it lacks the health-promoting and soothing effects of herbal aromas. This invention, through a 7:3 coupling ratio of activated minerals and nine Chinese herbal ingredients, maximizes the core functions while fully releasing the health-promoting effects of the herbs.

[0053] Office chairs are mostly made of synthetic materials, which have poor breathability and easily accumulate sweat and breed bacteria. The antibacterial rate of the seat cushion of this invention exceeds 99.9%, and it still maintains more than 99% even after 28 days, effectively inhibiting the growth of bacteria on the chair surface and preventing cross-infection when multiple people share the chair. The comparative example 7, which only added a single mugwort leaf, had an antibacterial rate of 96%, a durability of 88% after 28 days, and a limited deodorizing effect. The nine-ingredient compound of this invention uses active ingredients such as eugenol and eucalyptol contained in cloves and mugwort leaves to specifically inhibit specific drug-resistant strains, while agastache, atractylodes, and eupatorium inhibit molds and anaerobic bacteria. Together with the broad-spectrum antibacterial effect of silver ions and the physical antibacterial effect of minerals, it synergistically combats microorganisms from three dimensions: chemical, physical, and biological. The antibacterial spectrum complements each other, greatly reducing the risk of drug resistance, and achieving a comprehensive antibacterial effect that is broad-spectrum, highly efficient, long-lasting, and free of drug resistance. It has a 92% ammonia removal rate, releases natural herbal fragrance, and keeps the office space fresh for a long time. The product requires no energy, can be moved at any time, and is easy to use.

[0054] Example 4 The bed pad product prepared using the method of this invention is laid on the nursing beds in nursing homes, rehabilitation centers, postpartum care centers and other institutions as a functional nursing pad; the product is 3mm thick, with a smooth and soft surface, and can directly contact the bed sheet.

[0055] Patients who are bedridden for extended periods are at high risk of developing bedsores due to pressure on local tissues. This invention's nursing pad continuously emits far-infrared rays (93% emissivity), acting on pressure points to promote local microcirculation and metabolism, thus helping to prevent bedsores. It generates 850 negative oxygen ions / cm³, creating a fresh and soothing microenvironment for recovery. To verify the impact of the adhesive system on functional release, the applicant set up a comparative example 8 using ordinary polyurethane adhesive. Test results showed that the far-infrared emissivity of comparative example 8 decreased to 88% due to the dense adhesive film shielding, and the negative oxygen ion concentration decreased to 620 / cm³, with slight skin irritation. In contrast, the chitosan edible gum system of this invention naturally forms a micron-level porous network structure during the drying and film-forming process, acting like three-dimensional interconnected molecular channels, allowing unobstructed far-infrared radiation, free diffusion of negative oxygen ions and herbal aromas. Furthermore, the positive charge carried by chitosan itself can assist in antibacterial activity, further enriching the antibacterial system. The product is non-irritating and fully meets the high safety requirements of health and wellness institutions.

[0056] In terms of antibacterial and deodorizing properties, the nursing pad of this invention exhibits an antibacterial rate of over 99.9% against Staphylococcus aureus and Escherichia coli, maintaining a persistence of over 99% for 28 days, effectively reducing the risk of infection. In contrast, the comparative example 5, treated only with hydrogen peroxide, showed a 28-day antibacterial persistence reduced to 40%, confirming that the antibacterial efficacy cannot be sustained without long-term silver ion loading. The ternary activation system of this invention, through citric acid bridging, enables precise spatiotemporal synergy between hydrogen peroxide activation and silver ion loading, with silver ions firmly anchored to the mineral surface, ensuring that the nursing pad's efficacy does not diminish under complex environments such as long-term contact with patient sweat and excrement. The aromatic and deodorizing properties of the nine Chinese herbal medicines, such as patchouli, atractylodes, and eupatorium, can remove the damp, musty, and medicinal odors commonly found in wards, achieving an ammonia removal rate of 92%, far superior to the 65% of the comparative example 6 without Chinese herbal medicines. The refreshing aroma of eupatorium and peppermint helps to soothe patients' emotions, achieving holistic care for both mind and body.

[0057] Example 5 The cushion of this invention can be laid on the sofa in the living room or the chair in the home theater, with a thickness of 2 to 3 mm. It can be freely cut according to the size of the sofa seat. When family members are resting, the cushion emits far-infrared rays (93% emissivity) and releases negative oxygen ions (850 ions / cm³) all day long without any operation. This makes leisure time a passive health care process, promoting blood circulation in the buttocks and legs and relieving fatigue from sitting for a long time. If six-ring stone (comparative example 1, far-infrared 82%, negative oxygen ion 510 ions / cm³) or tourmaline (comparative example 2, far-infrared 80%, negative oxygen ion 560 ions / cm³) are used alone, the health care effect is significantly inferior. This invention achieves a significant leap in functional indicators through the synergistic effect of the two in a 1:1 ratio.

[0058] Sofas are frequently used areas in the home and are easily contaminated by pet hair, food scraps, and human sweat. This invention's seat cushion utilizes a synergistic combination of hexagonal stone and tourmaline, a ternary activation system for deep processing, and a compound of nine traditional Chinese herbs to construct a quadruple antibacterial system. This system comprises silver ion chemical antibacterial, mineral physical antibacterial, herbal biological antibacterial, and chitosan positive charge-assisted antibacterial, along with a full-chain deodorization mechanism consisting of physical adsorption, chemical decomposition, and aromatic masking. Comparative Example 3, without activation treatment, had an antibacterial rate of only about 70%, with a 28-day durability dropping to 45%, and some powder shedding. In contrast, this invention's product exhibits no powder shedding, an antibacterial rate exceeding 99.9%, and excellent durability. Comparative Example 6, without added traditional Chinese herbs, had a deodorization rate of only 65%, while this invention achieves a 92% deodorization rate. It continuously decomposes and adsorbs pet odors, smoke, and food odors, releasing natural herbal fragrances to keep the living room air fresh for a long time. Made entirely of food-grade materials, it is safe for families with young children and pets, with no chemical residues or safety risks.

[0059] Example 6 The seat cushion of this invention is cut and laid on the driver's seat or passenger seat of a car. It is 2mm thick and the base fabric is non-slip dotted fabric. It is stable and does not shift during driving. When drivers drive for a long time, their waist and hips are under pressure. The cushion can continuously emit far-infrared rays to promote blood circulation and relieve driving fatigue. The aroma of mint and other herbs can refresh the mind and improve driving concentration.

[0060] The enclosed nature of car cabins makes it easy for odors to accumulate under air conditioning circulation. This invention's car seat cushion boasts a 93% far-infrared emissivity and 850 negative oxygen ions / cm³, effectively purifying the seat's microenvironment. In contrast, using ordinary polyurethane adhesives (Comparative Example 8) reduces the far-infrared emissivity to 88% and negative oxygen ions to 620 / cm³ due to film shielding, and also introduces irritants, making it unsuitable for the confined space of a car. This invention's chitosan system is safe and non-irritating, with a porous structure ensuring the free release of functional substances. The cushion exhibits an antibacterial rate exceeding 99.9%, maintaining over 99% for 28 days, and a 92% ammonia removal rate. It effectively absorbs and decomposes sweat and smoke odors in the car, releasing a natural fragrance and significantly improving cabin air quality. The product is energy-efficient, noiseless, and ready to use immediately, independent of the vehicle's power system, making it safe and convenient to use.

[0061] Based on the above application examples and comparative experimental data, this invention, through a full-chain innovation involving synergistic mineral compounding, synergistic activation system, synergistic functional system, and synergistic molding system, enables the health-preserving pad to achieve comprehensive performance with a far-infrared emissivity of 93%, an antibacterial rate of over 99.9%, a durability of over 99% for 28 days, an ammonia removal rate of 92%, and 850 negative oxygen ions / cm³ under zero-energy consumption conditions. Moreover, it is non-irritating to the skin and fully meets the core needs of health preservation and safety and environmental protection in diverse scenarios such as home, office, health care, and in-vehicle use.
