Description

Technical Field

[0001] This application relates to the field of mattresses, and more particularly to a microcirculation therapy mat. Background Technology

[0002] A physiotherapy mat is a type of mattress that can promote blood circulation and improve microcirculation. When the body experiences fatigue, muscle tension, or other discomfort, a physiotherapy mat can be used to provide appropriate relief and improve these symptoms.

[0003] When using a physiotherapy pad, one usually needs to lie on a mattress for relief, which requires a relatively long period of contact with the pad. Generally, physiotherapy pads need to be heated to achieve better therapeutic effects. However, with prolonged use and contact with the pad, the constant friction between the limbs and the pad's surface can easily cause damage to the fabric, reducing the comfort of using the pad. Therefore, this needs to be improved. Summary of the Invention

[0004] To improve the wear resistance of physiotherapy pads, this application provides a microcirculation physiotherapy pad.

[0005] The microcirculation therapy pad provided in this application adopts the following technical solution: A microcirculation therapy pad includes a therapy component and a fabric component. The fabric component covers the outside of the therapy component and includes a wear-resistant layer, a graphene air layer, a graphene fiber layer, a silk-like cotton layer, a brushed fabric layer, a needle-cotton layer, a sponge layer, and a mesh breathable layer. The therapy component is located between the brushed fabric and the needle-cotton fabric. The wear-resistant layer is formed by coating the surface of the graphene air layer with a wear-resistant coating, and the wear-resistant coating includes the following components in parts by weight: 500-560 parts of coating substrate, 60-70 parts of antibacterial sustained-release microcapsules, 120-160 parts of abrasion-resistant component, 12-16 parts of softener, and 10-16 parts of defoamer; The wear-resistant components include aramid fibers, dopamine, and silica.

[0006] By adopting the above technical solution, using the graphene air layer and graphene fiber layer as the outer layer of the fabric component, it can achieve moisture absorption and perspiration wicking, antistatic and antibacterial effects, thereby promoting the effect of the physiotherapy pad. Moreover, the above-mentioned fabric layer has moderate softness and hardness and excellent breathability, which can effectively improve the comfort during use. At the same time, the surface of the graphene air layer is coated with a wear-resistant coating to form a wear-resistant coating on the surface of the graphene air layer, which can reduce the wear of the graphene air layer fabric and thus extend the service life of the physiotherapy pad. The wear-resistant component in the wear-resistant coating is prepared by compounding dopamine, aramid fiber and silica, which can give the wear-resistant component good compatibility. Coating dopamine on the surface of aramid fiber to obtain nano-units, and after silica is generated on the surface, a wear-resistant component with hydrophobic properties is obtained, which improves the wear resistance and the overall mechanical properties of the coating.

[0007] Preferably, the wear-resistant component is prepared by the following method: Nano-aramid fibers were mixed with deionized water to obtain an aramid fiber dispersion. Dopamine was added to adjust the pH to alkaline, and the mixture was stirred and reacted. After the reaction, the mixture was washed to obtain dopamine-modified aramid fibers. The dopamine-modified aramid fibers were then mixed with anhydrous ethanol, ammonia was added, and the mixture was sonicated. While stirring, the temperature was increased, and tetraethyl orthosilicate and 1H,1H,2H,2H-perfluorodecyltriethoxysilane were added. The mixture was stirred for 4 hours, and then 1H,1H,2H,2H-perfluorodecyltriethoxysilane was added again. The mixture was stirred and reacted for 3 hours to obtain the wear-resistant component.

[0008] By adopting the above technical solution, dopamine is coated on the surface of aramid fiber, and nano-silica particles are grown in situ on the surface through tetraethyl orthosilicate. Low surface energy modification is performed using 1H,1H,2H,2H-perfluorodecyltriethoxysilane, which gives the component superhydrophobic properties. As a result, the prepared wear-resistant component has good wear resistance and mechanical properties, as well as good hydrophobic properties, which gives the prepared physiotherapy pad good wear resistance and breathability.

[0009] Preferably, the mass ratio of the aramid fiber to dopamine is 1:(1.12-1.18).

[0010] By adopting the above technical solution, and preferably having the mass ratio of dopamine to aramid fiber within the above range, the stability of the prepared dopamine-modified aramid fiber can be further improved.

[0011] Preferably, the mass ratio of the dopamine-modified aramid fiber to tetraethyl orthosilicate is 1:(0.45-0.49).

[0012] By adopting the above technical solution, and preferably within the above range the mass ratio of dopamine-modified aramid fiber to tetraethyl orthosilicate, the stability of the prepared dopamine-modified aramid fiber can be further improved.

[0013] Preferably, the antibacterial sustained-release microcapsules comprise daylily fragrance, polyvinyl alcohol, and ε-polylysine.

[0014] Preferably, the antibacterial sustained-release microcapsules are prepared by the following method: Daylily fragrance was mixed with isophorone diisocyanate to obtain an oil phase. Polyvinyl alcohol was mixed with deionized water to obtain a polyvinyl alcohol dispersion. The polyvinyl alcohol dispersion was heated to the reaction temperature, and the oil phase was added to the polyvinyl alcohol dispersion. Emulsifiers and chain extenders were added and stirred to obtain a daylily fragrance pre-microcapsule emulsion. ε-polylysine was mixed with deionized water to obtain an ε-polylysine aqueous solution. The ε-polylysine aqueous solution was added to the daylily fragrance pre-microcapsule emulsion, and the reaction was carried out while maintaining the reaction temperature and stirring to obtain antibacterial sustained-release microcapsules.

[0015] By adopting the above technical solution, the volatile components in daylily fragrance are beneficial to human health. When combined with a therapeutic pad, it can further enhance the effect of promoting human circulation. At the same time, it has an antibacterial effect and can work synergistically with graphene fabric to inhibit bacteria. By preparing microcapsules with ε-polylysine and polyvinyl alcohol to encapsulate daylily fragrance, the daylily fragrance can be released slowly, and the phenomenon of rapid oxidation and inactivation of daylily fragrance can be reduced, so that daylily fragrance can play a long-term role. Moreover, the surface roughness of the prepared microcapsules is improved, which can stably adhere to the fiber surface, thereby improving the stability of the antibacterial slow-release microcapsules and maintaining the breathability of the fabric, keeping the fabric comfortable.

[0016] Preferably, the mass ratio of daylily fragrance, polyvinyl alcohol and ε-polylysine is 1:1.1:(0.69-0.75).

[0017] By adopting the above technical solution, and optimizing the mass ratio of daylily fragrance, polyvinyl alcohol and ε-polylysine within the above range, the overall performance of the prepared antibacterial sustained-release capsules can be further improved.

[0018] Preferably, the emulsifier includes Tween-80.

[0019] Preferably, the reaction temperature is 50-60℃.

[0020] Preferably, the wear-resistant coating is prepared by the following method: The coating substrate, antibacterial slow-release microcapsules, abrasion-resistant components, softener and defoamer are mixed and stirred to obtain an abrasion-resistant coating.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. A wear-resistant coating is applied to the surface of the graphene air layer of the fabric component, so that a wear-resistant layer is formed on the surface of the graphene air layer. The wear-resistant components in the wear-resistant coating include aramid fiber, dopamine and nano silica, which can play a good wear-resistant role and can synergistically improve the overall mechanical properties of the wear-resistant coating. The resulting wear-resistant layer has good wear resistance, thereby improving the overall service life of the physiotherapy pad. 2. The wear-resistant filler also contains antibacterial sustained-release microcapsules, which are prepared by daylily fragrance, ε-polylysine and polyvinyl alcohol. Daylily fragrance has good antibacterial effect and its volatile components are beneficial to promoting human circulation. Encapsulating daylily fragrance in the microcapsule structure allows the daylily fragrance to be released slowly. On the one hand, the antibacterial sustained-release microcapsules can have a synergistic antibacterial effect with the graphene air layer and graphene fiber layer. On the other hand, it can also further promote the effect of the therapeutic pad on promoting human circulation. Detailed Implementation

[0044] Comparative Example 1 Comparative Example 1 is based on Example 3. In Comparative Example 1, the wear-resistant component was prepared by ultrasonically dispersing dopamine-modified aramid fibers with anhydrous ethanol.

[0045] Performance testing The following performance tests were conducted on the physiotherapy pads prepared in Examples 1-12 and Comparative Example 1: (1) Wear resistance test Using ISO 5981-2007 as the testing standard, the abrasion resistance of the side of the sample with the abrasion layer was tested. Each sample was tested three times, and the average value was taken. The test results were recorded in Table 1.

The antibacterial rate of the sample was measured after 1 day and 7 days. Each sample was tested three times, and the average value was taken. The test results were filled in Table 1.

[0048] Table 1 Performance test results of Examples 1-13 and Comparative Example 1

[0049] Data Analysis As shown in Table 1, the abrasion resistance of Examples 1-3 is 6600 cycles or more, indicating that the physiotherapy pad prepared in this application has good abrasion resistance. The contact angle of Examples 1-3 is 160° or more, indicating that the physiotherapy pad prepared in this application has good hydrophobic properties. The antibacterial rate of Escherichia coli and Staphylococcus aureus in Examples 1-3 is 99.5% or more, indicating that the physiotherapy pad prepared in this application has good antibacterial properties. After 7 days of curing, the antibacterial rate of Escherichia coli and Staphylococcus aureus in Examples 1-3 is 94% or more, indicating that the physiotherapy pad prepared in this application has long-lasting antibacterial properties.

[0050] In Examples 4 and 5, the mass ratio of nano-aramid fibers to dopamine in the preparation of dopamine-modified aramid fibers was not within the range specified in this application. When the dopamine content was too high, the dopamine layer coating the surface of the aramid fibers was too thick, making it difficult to exhibit the mechanical properties of the nano-aramid fibers. When the dopamine content was too low, it was difficult to uniformly coat the surface of the nano-aramid fibers with a dopamine layer, which affected the subsequent growth of nano-silica and the overall performance of the wear-resistant component. Therefore, the various properties of Examples 4 and 5 were reduced.

[0051] In Examples 6 and 7, the dopamine-modified aramid fibers and tetraethyl orthosilicate used in preparing the wear-resistant components were not within the scope defined in this application. When the content of tetraethyl orthosilicate was too low, the uniformity of the nano-silica particles grown on the surface of the dopamine layer decreased, and the surface roughness was too small, affecting the hydrophobic properties and stability. When the content of tetraethyl orthosilicate was too high, too many nano-silica particles were generated on the surface of the dopamine layer, affecting the dispersion performance of the wear-resistant components and further affecting the stability of the wear-resistant coating. Therefore, all properties of Examples 6 and 7 decreased.

[0052] In Examples 8 and 9, the mass ratios of daylily fragrance, polyvinyl alcohol, and ε-polylysine in the preparation of antibacterial sustained-release microcapsules were not within the range specified in this application. When the content of ε-polylysine was too low, the modification effect on the microcapsules was weak, the surface smoothness of the microcapsules was high, and the adhesion between the microcapsules and the fabric was poor, thus affecting the stability of the antibacterial sustained-release capsules. When the content of ε-polylysine was too high, the particle size of the prepared antibacterial sustained-release microcapsules was too large, resulting in inconsistent particle sizes and affecting the stability of the antibacterial sustained-release microcapsules. Therefore, the performance of Examples 8 and 9 was reduced.

[0053] In Examples 10 and 11, the reaction temperatures during the preparation of antibacterial sustained-release microcapsules were outside the range specified in this application. When the reaction temperature was too low, the components were difficult to disperse, resulting in poor interfacial polymerization and affecting the stability of the antibacterial sustained-release microcapsules. When the reaction temperature was too high, the reactions in the system were too fast, inhibiting the formation of macromolecular polymers and thus affecting the preparation of the antibacterial sustained-release microcapsules. Therefore, the performance of Examples 10 and 11 was reduced.

[0054] Example 12 did not use ε-polylysine to modify the pre-made microcapsules of daylily fragrance. On the one hand, the surface smoothness of the pre-made microcapsules of daylily fragrance was difficult to improve, and the binding effect between them and the fabric fibers was reduced. On the other hand, without the addition of ε-polylysine, it was difficult to further protect the daylily fragrance, the thermal stability was reduced, the daylily fragrance was lost too quickly, and it was difficult to achieve a long-lasting antibacterial effect.

[0055] In Comparative Example 1, the wear-resistant component was only a mixture of dopamine-modified aramid fibers and anhydrous ethanol. The aramid fibers without added tetraethyl orthosilicate did not generate nano-silica on the surface. Therefore, both the wear resistance and hydrophobicity were reduced.

[0056] This specific embodiment is merely an explanation of this application and is not intended to limit it. Based on the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this application. The technical scope of this application is not limited to the contents of the specification but must be determined according to the scope of the claims.
