Description

Technical Field

[0001] This invention belongs to the field of functional artificial board technology, specifically an antibacterial and anti-cat and canine virus pet board and its preparation method, particularly a pet board that combines excellent surface wear and scratch resistance, broad-spectrum antibacterial properties, and specific anti-cat and canine virus functions, suitable for pet bedding. Background Technology

[0002] With the continuous growth of pet ownership, the pet consumer market is expanding, leading to a surge in demand for related pet home furnishings, especially pet housing (dog houses and cat houses). Traditional whole-house customization of pet housing often uses materials such as ordinary wood, particleboard, and fiberboard. These materials exhibit several drawbacks in actual use: First, their surface hardness is insufficient, making them susceptible to scratches from pets (especially dogs and cats), affecting aesthetics and lifespan. Second, the boards themselves lack antibacterial and anti-mildew properties, easily breeding bacteria (such as Pasteurella, Salmonella, and Campylobacter) and causing mold growth and odors after prolonged contact with pet urine, saliva, and other bodily fluids, harming both pets and the indoor environment. More importantly, ordinary boards cannot effectively inhibit or kill specific viruses that pose a significant threat to pet health, such as feline calicivirus (FCV) and canine distemper virus (CDV), posing a risk of cross-infection.

[0003] To enhance the durability and health performance of whole-house custom-made panels, various antibacterial or antiviral functional panels have emerged in existing technologies. For example, some technologies add nano-inorganic antibacterial agents (such as nano-titanium dioxide, nano-silver, and nano-zinc oxide) or photocatalysts to the impregnating adhesive, utilizing their photocatalytic or metal ion slow-release effects to achieve antibacterial properties. Other technologies use natural plant extracts as antibacterial and antiviral components, compounding them in resins or loading them onto decorative layers in microencapsulation form. Research also suggests combining organic antibacterial agents (such as quaternary ammonium salts and biguanides) with inorganic antibacterial agents to achieve synergistic effects and a broader spectrum of antibacterial efficacy.

[0004] However, the following shortcomings still exist when applying these existing technologies to the research and development of materials specifically for pet bedding: (1) Single function and weak targeting: Most existing technologies are mainly aimed at common bacteria or viruses in human living environment (such as Escherichia coli, Staphylococcus aureus, influenza virus), and lack effective attention and verification of pet environment-specific pathogens (such as feline calicivirus, canine distemper virus); (2) Insufficient wear resistance: The design focus of existing antibacterial and antiviral boards is mostly on the addition and maintenance of functional components, often neglecting the enhancement of surface hardness and wear resistance; for bedding materials that need to withstand frequent scratching by pets, their surface is easily damaged, resulting in the destruction of the functional layer and the antibacterial and antiviral function is difficult to last. (3) Shallow protective layer: Most existing solutions concentrate the functional components in the surface impregnation paper or coating. Once the surface is worn, the function is lost. There is a lack of antibacterial treatment on the substrate itself, which cannot fundamentally prevent internal mold and bacterial growth caused by liquid penetration into the substrate. (4) Complex or expensive composition system: Some solutions rely on precious metal nanomaterials (such as nano silver) or complex plant extract compound systems, which are expensive and have complicated production processes, making them unsuitable for large-scale application in the pet consumer product market.

[0005] Therefore, there is an urgent need to develop a special pet board that is cost-effective, has a feasible manufacturing process, and possesses excellent wear and scratch resistance, deep antibacterial and anti-mildew properties, as well as highly effective antiviral properties against cats and dogs, in order to meet the urgent demand of the pet home market for healthy, safe, and durable products. Summary of the Invention

[0009] Furthermore, in step 12), the high-temperature fumigation treatment is performed at a temperature of 95-125°C for 35-60 minutes; the fumigation treatment is performed at a temperature of 55-75°C, a relative humidity of 75-95%, and a time of 60-120 minutes.

[0010] Furthermore, the parameters for the high-temperature treatment are selected based on the thickness of the substrate: in: This refers to the high-temperature processing temperature. This refers to the high-temperature processing time; The substrate is a plain board; The parameters for the fumigation treatment are selected based on the thickness of the substrate board: in: For fumigation humidity; This refers to the fumigation temperature; It is a base material board.

[0011] Further, in step 12), during the fumigation treatment, the plant extract fumigation water is made by mixing purified water and antibacterial plant extract mixed oil in a volume ratio of 1:1; and / or, during the fumigation treatment, the circulating wind speed in the fumigation chamber is 6-10 m / s.

Attached Figure Description

[0018] To make the objectives, technical solutions, and beneficial effects of this invention clearer, the following figures are provided for illustration: Figure 1 This is a flowchart illustrating the preparation method of the antibacterial and antiviral pet board of the present invention. Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0020] like Figure 1 As shown in the figure, the preparation method of the antibacterial and antiviral cat and dog pet board in this embodiment includes the following steps.

[0021] Step 1: Preparation of antibacterial substrate: A substrate board is provided, and the substrate board is subjected to antibacterial treatment to obtain an antibacterial substrate. Specifically, in this embodiment, the antibacterial treatment method includes the following steps.

[0022] 11) Coating treatment: The substrate board is sprayed, rolled or vacuum pressure penetrated with an antibacterial treatment agent; the antibacterial treatment agent is an antibacterial liquid obtained by mixing emulsified oil and pure water, and the emulsified oil is obtained by emulsifying garlic oil or tea tree oil.

[0023] Specifically, the parameters of garlic oil are: relative density: 1.050-1.090; refractive index: 1.559-1.579; acid value: 3mgKOH / G; allicin content: over 99%.

[0024] The test results for tea tree oil are shown in Table 1.

[0025] Table 1. Detection results of tea tree oil In the coating process, the antibacterial solution is prepared by mixing emulsified oil and purified water in a 1:1 volume ratio. The substrate can be fiberboard, particleboard, oriented strand board, blockboard, or plywood, etc.

[0026] The spraying or roller coating conditions are as follows: heat the substrate board to 50-65℃, apply antibacterial liquid to both sides of the substrate board at a rate of 20-30 ml / m², and then dry at 75-95℃ for 1-3 minutes.

[0027] The vacuum pressure infiltration treatment conditions are as follows: place the substrate board into a vacuum container, apply pressure to infiltrate with antibacterial solution for 10-15 minutes, and then dry at 75-95℃ for 3-5 minutes.

[0028] 12) High-temperature fumigation treatment: The substrate board is subjected to high-temperature treatment and fumigation treatment in sequence. The humidification medium used in the fumigation treatment is plant extract fumigation water containing antibacterial plant extract mixed oil. After fumigation, the board is stacked for curing.

[0029] Specifically, in the high-temperature fumigation treatment, the temperature is 95-125℃, and the time is 35-60 minutes. Alternatively, the fumigation temperature is 55-75℃, the relative humidity is 75-95%, and the time is 60-120 minutes. During fumigation, antibacterial plant extract mixed oil is added to the humidifying water to form plant extract fumigation water. Specifically, the plant extract fumigation water is made by mixing purified water and antibacterial plant extract mixed oil at a 1:1 volume ratio. After fumigation, the substrate is stacked and cured at room temperature for at least 24 hours to obtain the antibacterial substrate. During fumigation, the circulating air velocity in the fumigation chamber is 6-10 meters per second.

[0030] Specifically, in this embodiment, the parameters for high-temperature treatment are selected based on the thickness of the substrate slab, as follows: in: This refers to the high-temperature processing temperature. This refers to the high-temperature processing time; It is a base material board.

[0031] In this embodiment, the fumigation parameters are selected based on the thickness of the substrate slab, as follows: in: For fumigation humidity; This refers to the fumigation temperature; It is a base material board.

[0032] Step 2: Prepare wear-resistant, anti-cat and canine virus impregnated paper.

[0033] 21) Provide thickened tensile-resistant decorative paper.

[0034] Ordinary impregnated paper is not scratch-resistant and is prone to cracking due to changes in ambient temperature and humidity. Therefore, it cannot be used for making pet bedding. In this embodiment, the thickened tensile-resistant decorative paper is made of wood fiber pulp mixed with cotton fibers with strong water absorption capacity, and a layer of non-waterproof kraft paper with a basis weight of 80g / m² is glued to the back of the decorative paper. This two-layer thickened decorative paper has the advantages of good toughness and high tensile strength.

[0035] 22) Prepare an antibacterial and antiviral solution for cats and dogs, comprising polyhexamethylene biguanide hydrochloride or quaternary ammonium salt, purified water, and emulsified oil. In this embodiment, the composition of the antibacterial and antiviral solution for cats and dogs is: the volume ratio of polyhexamethylene biguanide hydrochloride or quaternary ammonium salt, purified water, and emulsified garlic oil is 2:7:1.

[0036] 23) The thickened tensile decorative paper is impregnated with the antibacterial and anti-cat and canine virus liquid and dried to obtain anti-cat and canine virus paper.

[0037] In this embodiment, thickened tensile decorative paper is impregnated with antibacterial and anti-cat and dog virus liquid, with an impregnation amount of 10-20 ml / m². After impregnation, it is dried in an environment of 110-125℃ until the moisture content is ≤7%, thus obtaining tensile, antibacterial and anti-cat and dog virus decorative paper (hereinafter referred to as "anti-cat and dog virus paper").

[0038] 24) Preparation of antibacterial and antiviral mixed adhesive: Add the antibacterial and antiviral cat and dog liquid and alumina or silicon carbide wear-resistant material to melamine resin and / or urea-formaldehyde resin adhesive to obtain mixed adhesive.

[0039] In this embodiment, an antibacterial and antiviral solution for cats and dogs is added to the melamine and urea-formaldehyde resin adhesive. Specifically, the amount of antibacterial and antiviral solution added is 4% of the total weight of the adhesive. Then, aluminum oxide or silicon carbide wear-resistant material is added to it. The mesh size of the aluminum oxide or silicon carbide wear-resistant material is 200-500 mesh, and the amount added is 80-100 grams per square meter, to obtain a wear-resistant and antiviral mixed adhesive for cats and dogs.

[0040] 25) The anti-cat and canine virus paper is impregnated with the antibacterial and antiviral mixed adhesive and dried to obtain abrasion-resistant anti-cat and canine virus impregnated paper.

[0041] Anti-canine virus paper is impregnated twice with the aforementioned antibacterial and antiviral mixed adhesive. The total impregnation amount for both impregnations is 210-250 g / m², with a total resin content of 100-160%. The drying temperature after impregnation is 110-135℃, resulting in a wear-resistant anti-canine virus impregnated paper. Specifically, the resin content in the first impregnation is 30% of the total resin content, and the resin content in the second impregnation is higher than that in the first; the final result after both impregnations reaches the required total resin content.

[0042] Step 3: Finished Product Lamination: Abrasion-resistant anti-cat and canine virus impregnated paper is applied to at least one surface of the antibacterial substrate, and then hot-pressed to obtain the antibacterial and anti-cat and canine virus pet board. Specifically, before hot-pressing, an antibacterial plant extract mixture is sprayed onto the surface of the antibacterial substrate to be laminated, at a rate of 5 ml / m². This serves two purposes: firstly, to increase antibacterial properties, and secondly, to prevent the appearance of dried flowers on the surface during hot-pressing. In this embodiment, abrasion-resistant anti-cat and canine virus impregnated paper is uniformly hot-pressed onto both sides of the antibacterial substrate to obtain the antibacterial and anti-cat and canine virus pet board.

[0043] This embodiment also presents an antibacterial and anti-cat and canine virus pet board prepared by the preparation method described above in this embodiment.

[0044] The technical effects of this patent application will be further explained in detail below with reference to specific implementation.

[0045] Example 1: Preparation of an antibacterial and antiviral pet board for cats and dogs This embodiment provides a method for preparing an antibacterial and antiviral pet board for cats and dogs, and the specific steps are as follows.

[0046] 1. Preparation of antibacterial substrate We provide 12mm thick particleboard as the substrate. Antibacterial treatment is achieved through a combination of coating and high-temperature fumigation.

[0047] 1.1 Coating treatment: Preparation of antibacterial solution: Mix emulsified tea tree oil and purified water at a volume ratio of 1:1 and stir well.

[0048] Preheat the particleboard to 60°C.

[0049] The antibacterial liquid was evenly applied to both sides of the raw board using a roller coating method at a coating amount of 25 ml / m².

[0050] The coated boards are then placed in an 85°C drying tunnel and dried for 2 minutes to allow the antibacterial components to be initially absorbed and fixed.

[0051] 1.2 High-temperature fumigation treatment: The coated board is sent into a high-temperature treatment chamber. Based on its thickness (d=12mm∈[12,15]), the parameters are selected according to the functional relationship: it is treated at 105℃ for 42 minutes.

[0052] After high-temperature treatment, the product is immediately transferred to a fumigation chamber for fumigation. The humidifying medium used for fumigation is plant-based fumigation water, which is a 1:1 volume mixture of purified water and antibacterial plant extract oil. The circulating air velocity inside the fumigation chamber is controlled at 8 m / s.

[0053] Based on the thickness of the board, select the fumigation parameters according to the functional relationship: control the fumigation temperature at 63℃, the relative humidity at 83%, and the fumigation treatment for 90 minutes.

[0054] After fumigation, the boards are removed and stacked at room temperature for curing for more than 24 hours to obtain antibacterial substrate.

[0055] 2. Preparation of wear-resistant, anti-cat and canine virus impregnated paper 2.1 Preparation of thickened tensile decorative paper: Wood fiber pulp mixed with 15% cotton fiber is used to make decorative base paper, and a layer of non-waterproof kraft paper with a basis weight of 80g / ㎡ is laminated on the back to obtain the thickened tensile decorative paper.

[0056] 2.2 Preparation of antibacterial and antiviral solution for cats and dogs: Take polyhexamethylene biguanide hydrochloride, purified water and emulsified garlic oil, mix them in a volume ratio of 2:7:1, stir evenly to obtain antibacterial and antiviral solution for cats and dogs.

[0057] 2.3 First Impregnation (Preparation of Anti-Cat and Canine Virus Paper): The thickened tensile-resistant decorative paper is impregnated in the above-mentioned antibacterial and anti-cat and canine virus solution, with the impregnation amount controlled at 15 ml / m². After impregnation, it is dried in a drying oven at 118°C until the moisture content is 6.5%, thus obtaining the anti-cat and canine virus paper.

[0058] 2.4 Preparation of antibacterial and antiviral mixed adhesive: Take 100 parts by weight of melamine resin adhesive with a solid content of 52%, add 4 parts by weight (i.e., 4% of the adhesive weight) of the above-mentioned antibacterial and antiviral cat and dog solution, and stir evenly. Then add 90 g / m² of 325 mesh alumina wear-resistant material (based on the adhesive area), and disperse evenly at high speed to obtain wear-resistant and antiviral cat and dog mixed adhesive.

[0059] 2.5 Second Impregnation (Preparation of Abrasion-Resistant Anti-Canine Virus Impregnated Paper): A two-stage impregnation process is used to treat the anti-canine virus paper. The first impregnation uses a mixed adhesive with a low resin content, resulting in a resin content of approximately 30% of the total target resin content after impregnation. The second impregnation uses a mixed adhesive with a higher resin content. The total impregnation amount for both impregnations is controlled at 230 g / m², with a total resin content of 135%. After impregnation, the paper is dried and cured at 125°C to obtain the abrasion-resistant anti-canine virus impregnated paper.

[0060] 3. Finished product pressing On the two surfaces of the antibacterial substrate obtained in step 1, spray an antibacterial plant extract mixture oil at a rate of 5 ml / m².

[0061] After cutting the wear-resistant anti-cat and canine virus impregnated paper obtained in step 2, it is used to cover both sides of the antibacterial substrate.

[0062] It is fed into a hot press and hot-pressed for 8 minutes at a pressure of 1.0 MPa and a temperature of 125°C.

[0063] After hot pressing, the product is cooled and trimmed to obtain the antibacterial and antiviral pet board for cats and dogs.

[0064] Comparative Example 1 The only difference from Example 1 is that the substrate is not subjected to any antibacterial treatment (i.e. step 1 is omitted), and ordinary particleboard is directly used for pressing in step 3.

[0065] Comparative Example 2 The only difference from Example 1 is that, when preparing the impregnated paper, no aluminum oxide or silicon carbide wear-resistant material is added to the mixed adhesive in step 24).

[0066] Performance testing: The performance of the boards obtained in Example 1 and Comparative Examples 1 and 2 was tested, and the results are shown in Table 2.

[0067] Surface abrasion resistance: Tested according to GB / T 18102-2020 "Impregnated Paper Laminate Wood Flooring" standard; Surface scratch resistance: Tested according to GB / T 17657-2013 "Test Methods for Physical and Chemical Properties of Wood-based Panels and Decorative Wood-based Panels"; Antimicrobial properties: Tested according to ISO 22196:2011 "Methods for evaluating the antimicrobial properties of surfaces of plastic products", the bacterial strain was Salmonella typhimurium; Antiviral properties: Tested according to ISO 21702:2019 standard "Measurement of antiviral activity of plastics and other nonporous surfaces", the viruses tested were feline calicivirus (FCV) and canine distemper virus (CDV).

[0068] Table 2 Performance Test Results Results analysis: As can be seen from the comparison between Example 1 and Comparative Example 1, the antibacterial and antiviral properties of the board are significantly improved by applying a coating and fumigation antibacterial treatment to the substrate. This indicates that the substrate treatment process of the present invention effectively constructs deep protection, avoiding the problem of functional failure due to minor surface damage.

[0069] A comparison of Example 1 and Comparative Example 2 shows that adding alumina or silicon carbide abrasion-resistant materials to the mixed adhesive significantly improves the surface scratch resistance of the board, making it suitable for use in scenarios where pets scratch it, while having little impact on the core antibacterial and antiviral functions. This confirms the effective combination of abrasion-resistant design and functional design.

[0070] The sheet material in Example 1 fully meets the design goals of surface abrasion resistance ≥2000 revolutions, scratch resistance ≥3N, antibacterial rate against specific bacteria ≥99%, and antiviral rate against feline and canine viruses ≥90%, demonstrating excellent overall performance. Specifically, in this example, surface abrasion resistance reaches 2000-4000 revolutions; scratch resistance reaches 3-4N; resistance to feline calicivirus and canine distemper virus can even reach up to 99.9%; and resistance to Pasteurella multocida and Salmonella typhimurium can even reach up to 99.99%.

[0071] Example 2: Changes in substrate treatment method and parameters The difference between this embodiment and Embodiment 1 lies in the antibacterial treatment method of the substrate and some parameters: The substrate is made of 18mm thick fiberboard.

[0072] The vacuum pressure permeation method used in the coating process was employed only: the raw plate was placed in a vacuum chamber, and the antibacterial solution prepared in Example 1 was injected, and permeation was carried out at a pressure of 0.8 MPa for 12 minutes. After removal, it was dried at 90°C for 4 minutes.

[0073] The subsequent impregnation paper preparation and lamination process are the same as in Example 1.

[0074] The resulting board was tested and found to have surface abrasion and scratch resistance comparable to that of Example 1, with an antibacterial rate ≥99% and antiviral rates ≥90% against both feline calicivirus and canine distemper virus. This indicates that both coating and fumigation treatments can independently impart good antibacterial properties to the substrate.

[0075] Example 3: Changing the active ingredient and impregnation parameters The difference between this embodiment and Embodiment 1 is that: Step 22) When preparing the antibacterial and antiviral solution for cats and dogs, use quaternary ammonium salt instead of polyhexamethylene biguanide hydrochloride, while keeping the other proportions unchanged.

[0076] In step 23), the temperature for the first impregnation and drying is adjusted to 115℃.

[0077] In step 25), the total resin content of the two impregnations is adjusted to 150%.

[0078] The performance test results of the obtained board are at the same excellent level as those of Example 1, indicating that the selection of polyhexamethylene biguanide hydrochloride or quaternary ammonium salt, as well as the adjustment of related process parameters within a given range, can achieve the purpose of this invention.

[0079] The above-described embodiments are merely preferred embodiments provided to fully illustrate the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are all within the scope of protection of the present invention. The scope of protection of the present invention is defined by the claims.
