Description

Technical Field

[0001] This invention relates to the field of wax block production technology, specifically to a wax block for a wax therapy machine and its preparation method. Background Technology

[0002] Wax therapy, as a long-standing physical therapy method, mainly utilizes heated wax to release sustained, gentle heat energy onto the affected area during the cooling process. This achieves therapeutic effects such as dilating capillaries, promoting local blood circulation, eliminating inflammation, relieving pain, and softening tissues. It is highly favored due to its ease of operation, low cost, and wide range of indications, and still holds an important position in the field of modern rehabilitation therapy.

[0003] Traditional wax therapy materials typically use paraffin as the main matrix, or are supplemented with small amounts of mineral wax, vegetable oil, etc. However, after long-term clinical practice and application, existing wax therapy materials have gradually revealed many technical defects that urgently need to be addressed, seriously affecting the treatment effect and user experience. Specifically, these defects manifest in the following aspects: 1. Insufficient flexibility and ductility: Traditional paraffin-based wax blocks are hard and brittle after cooling and solidification. When performing wax therapy, the solidified wax block is easily cracked or broken due to bending when it needs to be removed from curved surfaces of the body (such as joints, neck, etc.) or when it needs to be wrapped for treatment, and it cannot completely adhere to the treatment area.

[0004] 2. Prone to cracking and poor structural stability: Due to the single composition of the formula, there is a lack of effective synergistic toughening effect between the components. During the repeated heating and cooling cycle, impurities are introduced into the wax block. Over time, the wax block will become loose and brittle, and its service life will be greatly shortened. It is also prone to cracking during demolding and handling.

[0005] 3. Poor Detachability: In wax therapy machines, the wax block needs to be molded in a tray or container. After melting, the wax block adheres strongly to the surface of the tray, making it difficult to detach completely and smoothly from the tray after cooling and solidifying (i.e., poor detachability), which poses operational difficulties. Current technologies mainly address the issues of flexibility and adhesion by adding petrolatum, bio-cellulose, or traditional Chinese medicine extracts, but the problems of poor detachability and insufficient thermal stability are not yet fully addressed.

[0006] 4. Limitations in overall performance and safety: Some existing technologies attempt to improve performance by adding plasticizers, polymers, etc., which may introduce odors, reduce biocompatibility, or affect thermal stability. Some formulations produce wax blocks with poor adhesion, do not adhere tightly to the skin, and are prone to creating gaps, affecting the depth and uniformity of thermal action.

[0007] 5. Waste of resources: Wax blocks made by the layered waxing method can only be used once and cannot be repeatedly melted, resulting in waste of resources.

[0008] Against this backdrop, the present invention is dedicated to developing a wax block for a wax therapy machine that combines excellent flexibility, outstanding release properties, good thermal stability, reusability, and high safety, in order to meet the higher requirements of modern clinical practice for the comfort, efficiency, and safety of wax therapy technology. Summary of the Invention

[0009] To address the problems of insufficient flexibility, easy cracking, poor release properties, and irritating odor in existing wax therapy materials, this invention aims to provide a wax block for a wax therapy machine and its preparation method. The objectives of this invention include: 1. A wax block for a wax therapy machine with good flexibility and extensibility is provided, which can be bent without cracking after cooling and closely conform to the curvature of the human body.

[0010] 2. A wax block for a wax therapy machine with good detachment performance is provided. After melting and re-solidifying in the wax therapy machine, it can be easily and completely detached from the tray, which is convenient for operation.

[0011] 3. Provide a wax block for a wax therapy machine with excellent thermal stability and plasticity, ensuring stable performance and preventing aging and breakage during repeated melting and solidification cycles.

[0012] 4. Provide a wax block for a wax therapy machine that is highly safe, odorless, and biocompatible, made entirely of food-grade or medical-grade raw materials, to improve treatment comfort and safety.

[0013] 5. A wax block and its preparation process are provided, which involves one-time melting and wax production, is simple, and is suitable for industrial production.

[0014] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A wax block for a wax therapy machine is composed of the following components: 50-150 parts paraffin wax, 10-20 parts microcrystalline wax, 2-8 parts beeswax, 1-5 parts hot melt adhesive, and 0.1-0.5 parts silica.

[0015] Preferably, the paraffin wax is a fully refined paraffin wax of grade 52 to 60.

[0016] Preferably, the microcrystalline wax is one or both of 70# microcrystalline wax and 80# microcrystalline wax.

[0017] Preferably, the beeswax is natural yellow beeswax.

[0018] Preferably, the hot melt adhesive is an ethylene-vinyl acetate copolymer type hot melt adhesive.

[0019] Preferably, the paraffin wax, beeswax, microcrystalline wax, and hot melt adhesive are all food-grade or medical-grade raw materials.

[0020] A method for preparing wax blocks for a wax therapy machine includes the following steps: S1: Melting and mixing: According to the above proportions, put paraffin wax, microcrystalline wax and beeswax into a wax melting pot with stirring and heating functions, heat to 70-85℃, and keep stirring at a constant speed until all wax materials are completely melted into a clear liquid; S2: Add hot melt adhesive: Slowly add the hot melt adhesive in granular or small block form to the molten wax, keep the temperature at 80-85℃, and continue stirring for 20-40 minutes until the hot melt adhesive is completely dissolved and mixed evenly with the wax to form a uniform molten mixture. S3: Degassing and standing: Let the mixed molten liquid stand at 75-80℃ for 10-15 minutes to allow the air bubbles to escape fully; S4: Casting: Slowly pour the degassed molten mixture into a preheated standard wax block mold; S5: Cooling and demolding: Allow to cool naturally at room temperature until completely solidified, or use air cooling to assist in cooling, and then demold to obtain the wax block of the wax therapy machine.

[0021] Compared with the prior art, the beneficial effects of the present invention are: The wax block for the wax therapy machine prepared by the formula and preparation method of this invention has good ductility, adhesion and thermal stability, and can be repeatedly melted and reused; during the wax therapy process, it can fit closely to the treatment area, has good heat preservation effect, is not easy to break, and the raw materials used are all food grade or pharmaceutical grade, odorless, and highly safe, effectively improving the comfort, therapeutic effect and safety of wax therapy.

[0022] Specifically, it includes the following performance characteristics: Flexibility: Through the synergistic toughening effect of #70 microcrystalline wax, #80 microcrystalline wax and ethylene-vinyl acetate copolymer hot melt adhesive, the wax molecular chains intertwine to form a stable network structure, making the wax block flexible at room temperature. It can be bent to a large extent without breaking, which perfectly solves the problem of traditional wax blocks cracking when applied to curved surfaces such as joints, ensuring the integrity and fit of the treatment. Removability from the tray: After melting, the surface tension between the wax block and the metal tray is moderate. After cooling and solidifying, it can automatically shrink and is easy to remove completely and easily from the tray, which facilitates clinical operation and improves work efficiency. Thermal insulation effect: The wax block of this invention has a dense structure, high heat capacity, and good thermal stability. It can still maintain good physical properties and shape after multiple melting cycles, thus extending its service life. The addition of hot melt adhesive gives the wax block good plasticity and toughness. High safety: This invention uses all food-grade or medical-grade raw materials, which are non-toxic and harmless, and have no odor during heating and use, ensuring the comfort of the treatment environment and the health and safety of patients. The addition of beeswax makes the wax block adhere more tightly to the skin and keep warm for a longer time. To reduce costs, a "one-step melt mixing" process is adopted, in which paraffin wax, microcrystalline wax and beeswax are melted and directly added to hot melt adhesive and stirred evenly. This eliminates the need for complex layered coating or post-processing. This method not only reduces energy consumption and equipment costs, but also avoids the interface problems between layers in traditional multi-layer structures, ensuring the uniformity of wax block performance, facilitating the reuse of wax blocks and reducing resource waste.

Detailed Implementation

[0024] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows: A wax block for a wax therapy machine, by weight, is composed of the following components: 50-150 parts paraffin wax, 10-20 parts microcrystalline wax, 2-8 parts beeswax, 1-5 parts hot melt adhesive, and 0.1-0.5 parts silica.

[0025] Among them, the paraffin wax is fully refined paraffin wax of 52# to 60#; the microcrystalline wax is one or two of 70# and 80# microcrystalline wax; the beeswax is natural yellow beeswax; the hot melt adhesive is ethylene-vinyl acetate copolymer hot melt adhesive; the paraffin wax, beeswax, microcrystalline wax and hot melt adhesive are all food grade or medical grade raw materials.

[0026] In the above technical solution, the roles and synergistic effects of each component are as follows: Paraffin wax serves as the base matrix, providing the necessary heat capacity and phase change insulation properties for the wax block.

[0027] Microcrystalline wax is used to enhance the flexibility, internal structural strength, and shrinkage resistance of wax blocks, effectively preventing brittle cracking.

[0028] Beeswax improves the stickiness, smoothness, and gentle adhesion of the wax block to the skin, enhancing the user experience.

[0029] Hot melt adhesive, as a key modifier, is added during the melting stage to fully entangle its molecular chains with other wax components, forming a stable network structure. This improves the thermal stability and crack resistance of the wax block, significantly enhances its plasticity, toughness, and overall structural density, and gives the wax block better resistance to fracture when bent. It also helps to improve its release properties.

[0030] Silica, as a filler, reduces heat loss from the wax block and enhances its thermal insulation performance.

[0031] In this formula, paraffin wax serves as the base matrix, and the combination of 70# and 80# microcrystalline wax enhances the flexibility and strength of the wax block. Beeswax improves its viscosity and fineness, while ethylene-vinyl acetate copolymer hot melt adhesive significantly improves the plasticity and toughness of the wax block. Silica fills the gaps between molecules, enhancing the heat insulation performance of the wax block. The synergistic effect of each component overcomes the defects of traditional wax blocks.

[0032] This invention also provides a method for preparing the wax block for the above-mentioned wax therapy machine, comprising the following steps: S1: Melting and mixing: According to the above proportions, put paraffin wax, microcrystalline wax and beeswax into a wax melting pot with stirring and heating functions, heat to 70-85℃, and keep stirring at a constant speed until all wax materials are completely melted into a clear liquid; S2: Add hot melt adhesive: Slowly add the hot melt adhesive in granular or small block form to the molten wax, keep the temperature at 80-85℃, and continue stirring for 20-40 minutes until the hot melt adhesive is completely dissolved and mixed evenly with the wax to form a uniform molten mixture. S3: Degassing and standing: Let the mixed molten liquid stand at 75-80℃ for 10-15 minutes to allow the air bubbles to escape fully; S4: Casting: Slowly pour the degassed molten mixture into a preheated standard wax block mold; S5: Cooling and demolding: Allow to cool naturally at room temperature until completely solidified, or use air cooling to assist in cooling, and then demold to obtain the wax block of the wax therapy machine.

[0033] The preparation method of the present invention involves heating and melting paraffin wax, microcrystalline wax and beeswax, adding hot melt adhesive and silica and stirring evenly, then cooling and casting into a mold; this method involves one-time melting, is simple in process, and is easy to industrialize.

[0034] Example 1: A wax block for a wax therapy machine, by weight, is composed of the following components: 50 parts paraffin wax, 5 parts 70# microcrystalline wax, 12 parts 80# microcrystalline wax, 3 parts natural beeswax, 2 parts ethylene-vinyl acetate copolymer hot melt adhesive, and 0.1 parts silica.

The smoothness of the removal process and whether the wax blocks easily detach or break are observed to determine the ease of removal from the tray. See the attached document for details. Figure 4 As shown.

[0050] Odor: Ten volunteers were recruited to gently fan the wax block towards their nasal cavity from a distance of 10cm, and the smell of the wax block was identified and compared. The evaluation criteria were as follows: 0-2 points (None): No irritating or unpleasant odor.

[0051] 2-5 points (mild): There is a faint odor, but no discomfort.

[0052] 5-10 points (obvious): The odor is clearly noticeable and causes discomfort.

[0053] Finally, the highest and lowest scores were removed, and the average of the remaining scores was calculated.

[0054] The test results are as follows: , Note: Liquid state refers to wax blocks in a molten state; solid state refers to wax blocks kept at 53℃.

[0055] Conclusion: By analyzing and comparing the product prepared in Example 4 with the comparative example and common competing products on the market, the test results show that the product prepared in Example 4 of this invention performs well in terms of appearance, heat preservation performance, flexibility, detachability and irritating odor, and its overall performance is stronger than that of the comparative example and competing products.
