Description

Technical Field

[0001] The present invention relates to the technical field of insole manufacturing, and particularly to a preparation method of a Chinese herbal medicine comfort insole and an insole made by this method. Background Art

[0002] Insoles not only enhance the wearing comfort but also have various practical functions. By providing additional cushioning and support, insoles can effectively reduce the pressure on the feet during walking or exercise, preventing foot fatigue and pain. At the same time, insoles made of antibacterial materials can inhibit the growth of bacteria, reduce odors, and keep the shoe interior clean and hygienic. In addition, insoles can increase the friction between the shoes and the feet, improve stability, and reduce the risk of slipping or spraining. For specific occasions and needs, such as sports shoes, leather shoes, or high heels, choosing the right insoles can provide additional functions and protection, thus extending the service life of the shoes.

[0003] Existing Chinese herbal medicine insoles are usually prepared by mixing Chinese herbal medicines with other materials, using the natural antibacterial and odor-proof properties of Chinese herbal medicines to improve the functions of the insoles. However, directly mixing Chinese herbal medicines with polyethers to prepare insoles often results in incompatibility problems, causing the color blocks of the formed insoles to be dispersed, affecting the aesthetics and functions. In addition, due to the natural color of Chinese herbal medicines, the color fades during the preparation process as the liquid penetrates, resulting in large color differences in the finished insoles and making it difficult to adjust the color. At the same time, directly applying paint to increase the wear resistance of Chinese herbal medicine insoles will affect the pharmacological properties of Chinese herbal medicine insoles. These problems limit the wide application and market acceptance of Chinese herbal medicine insoles.

[0004] To solve the above technical problems, the present invention provides a new manufacturing process for Chinese herbal medicine insoles. This process first produces antibacterial and odor-proof polyurethane foam and then performs a forming treatment, solving the previous incompatibility and color block dispersion problems. At the same time, by using Chinese herbal medicine extracts to make insoles, the problem of large color differences in insoles is solved. This method not only improves the antibacterial and odor-proof effects of the insoles but also ensures the aesthetics and comfort of the insoles. At the same time, a dense wear-resistant layer is formed through a secondary reaction on the insole surface, greatly increasing the wear resistance of the insole. This insole has broad application prospects. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a preparation method of a Chinese herbal medicine comfort insole in view of the above-mentioned deficiencies of the prior art.

[0006] A preparation method of a Chinese herbal medicine comfort insole is characterized by including the following steps:

[0007] S1. Prepare component A: Mix the Chinese herbal medicine extract and polyether polyol to obtain component A;

[0008] S2. Prepare Component B: Put Component A, polyester polyol, surfactant, catalyst, and compatibilizer into Container A and mix them. After heating and stirring, Component B is obtained. The heating temperature is controlled at 40 - 60°C, the rotation speed is 50 - 80 revolutions per minute, and the stirring time is 1 - 1.5 hours.

[0009] S3. Prepare Component C: Pour diphenylmethane diisocyanate into Container B and heat it for standby to obtain Component C, where the heating temperature is 40 - 50°C.

[0010] S4. Mix Component B and Component C obtained in Steps S2 and S3 evenly to obtain the base material mixed component.

[0011] S5. Pour the base material mixed component obtained in Step S2 into the mold, then blow the mechanical bubbles with compressed air and burst them. After closing the mold, cure for 30 - 40 minutes to obtain the Chinese herbal medicine insole.

[0012] S6. Open the mold, evenly brush Component A on the insole precursor, then close the mold and heat and cure for 30 - 40 minutes. The heating temperature is controlled at 50 - 60°C to obtain the comfortable insole.

[0013] Adopting the above technical solution, by mixing the Chinese herbal medicine extract with polyether polyol to form component A, and then putting component A, polyester polyol, surfactant, catalyst, and compatibilizer into container A for mixing to prepare the insole substrate, it avoids the problem of large color difference in products caused by directly using Chinese herbal medicine itself in traditional Chinese herbal medicine insoles. Even when preparing insoles of different colors, a stable color mixing effect can be achieved, ensuring that the colors of the finished insoles are uniform. At the same time, it significantly solves the problem of incompatibility between Chinese herbal medicine and polyether, avoiding the phenomenon of color block dispersion in the molded insoles, improving the overall aesthetics and functionality of the insoles. Polyether polyol is mainly used to improve the elasticity and comfort of the insoles. Polyester polyol mainly acts as an adhesive, which binds various materials of the insole together, improving the integrity and stability of the insole, increasing the density of the insole, thereby enhancing the durability and wear resistance of the insole. The surfactant mainly plays the roles of wetting and emulsifying during the insole molding process. It can reduce the interfacial tension and increase the wettability of the interface, thereby improving the adhesion and permeability of the coating. At the same time, it can also play roles such as emulsifying, dispersing, and solubilizing during the preparation of component B, helping to mix various materials evenly during the preparation of component B. The catalyst plays a role in promoting chemical reactions during the insole molding process. It can accelerate the cross-linking reaction between polymer molecules and promote the curing and molding of materials. When diphenylmethane diisocyanate in component C is molded in step S3, by reacting with components such as polyester polyol and polyether polyol, it can increase the cross-linking density of the insole material, improve the elasticity and durability of the insole, promote foam formation, and at the same time control parameters such as the density and pore size of the foam, promoting the foaming and molding of the insole. At the same time, a secondary surface reaction occurs on the surface of the Chinese herbal medicine insole to form a dense wear-resistant layer. By forming a dense protective layer on the surface of the insole, it can effectively reduce wear and loss during daily use, extend the service life of the insole, and at the same time not affect the pharmacological properties of the Chinese herbal medicine insole.

[0014] The above method for preparing a Chinese herbal medicine comfortable insole can be further set as follows: The production process of the Chinese herbal medicine extract includes the following steps:

[0015] S1.1. Prepare basic Chinese medicinal materials: Scutellaria baicalensis, Angelica dahurica, Glycyrrhiza uralensis, Angelica sinensis;

[0016] S1.2. Place Scutellaria baicalensis, Angelica dahurica, Glycyrrhiza uralensis, and Angelica sinensis in container C, add alcohol and ionized water into container C, and seal it for soaking.

[0017] S1.3. Place container C soaked with Scutellaria baicalensis, Angelica dahurica, Glycyrrhiza uralensis, and Angelica sinensis in step S1.2 on an oscillator for oscillation. The left and right amplitude is 4 cm, the frequency is 50 times per minute, and the time is 1 hour to obtain mixture A.

[0018] S1.4. Filter the mixture in step S1.3 through a 10 - 100 mesh filter and then place it in container D 。

[0019] S1.5. Place the container D filled with the filtered mixture obtained in step S1.4 on the shaker again for secondary shaking; the amplitude of left - right shaking is 4 cm, the frequency is 200 times per minute, and the time is 1 hour to obtain mixture B.

[0020] S1.6. Place the container D filled with mixture B obtained in step S1.5 into a centrifuge for centrifugation to obtain the Chinese herbal medicine extract.

[0021] Adopting the above - mentioned technical solution, by using a shaker to perform high - frequency shaking on the container soaked with Scutellaria baicalensis, Angelica dahurica, Glycyrrhiza glabra and Angelica sinensis, it can effectively promote the full release of active ingredients in Chinese medicinal materials, improve the concentration and purity of the extract. After multiple shaking and centrifugation treatments, the active ingredients in the Chinese herbal medicine extract are concentrated, enhancing its antibacterial, anti - inflammatory, antioxidant and other pharmacological effects. At the same time, precisely controlling the soaking and shaking time ensures the stability of the active ingredients in the extract, avoiding oxidation and degradation caused by long - term exposure to air. Using a combined soaking method of ionic water and alcohol simplifies the complex steps of traditional Chinese medicine extraction, improves production efficiency, and reduces production costs. Through fine filtration and centrifugal separation technology, impurities and precipitates in the extract are removed, making the finally obtained Chinese herbal medicine extract purer and improving the overall quality of the product.

[0022] The above - mentioned method for preparing a Chinese herbal medicine comfortable insole can be further set as: when preparing component B in step S2, it further includes putting an antibacterial agent and an anti - odor agent into container A and stirring simultaneously.

[0023] Adopting the above - mentioned technical solution, the antibacterial agent can be a nano - silver antibacterial agent that can kill bacteria by destroying the bacterial cell membrane and inhibiting the activity of bacterial respiratory enzymes, effectively inhibiting bacterial growth and maintaining the cleanliness and hygiene of the insole. The anti - odor agent can be activated carbon that can adsorb properties to eliminate or reduce the odor in the insole and maintain the freshness and hygiene inside the shoe. Directly forming the antibacterial agent and the anti - odor agent in the polyurethane elastomer insole enables it to achieve an efficient antibacterial and deodorizing effect after contacting the sole of the foot.

[0024] The above - mentioned method for preparing a Chinese herbal medicine comfortable insole can be further set as: when preparing component B in step S2, it further includes putting a blowing agent and a hardening agent into container A and stirring simultaneously.

[0025] With the above technical solution, the role of the pore-forming agent is to form micropores during the molding of the Chinese herbal medicine insole, increase the air permeability and moisture absorption of the insole, adjust the softness, hardness and elasticity of the insole, improve the wearing comfort, and make the insole more comfortable. The role of the hardening agent is to harden the insole, increase its durability and abrasion resistance. By adding the hardening agent, the insole can be made more wear-resistant and wrinkle-resistant, and its service life can be extended. By controlling the components of the pore-forming agent and the hardening agent, the comfortable polyurethane antibacterial and deodorant insole has the characteristics of elasticity and comfort while having wear-resistant properties, improving the service life of the product, enabling it to achieve wear-resistant and pressure-resistant characteristics without an artificial leather-like wear-resistant layer. The pore-forming agent can be an aerogel with a porous structure to improve the air permeability and moisture absorption of the insole, and the hardening agent can be a polyurethane resin to improve the durability and abrasion resistance of the insole.

[0026] For the above-mentioned preparation method of a Chinese herbal medicine comfortable insole, it can be further set as follows: when preparing component C in step S3, it also includes putting butyl acetate and xylene into container B and stirring simultaneously.

[0027] With the above technical solution, the mixed use of butyl acetate and xylene can optimize the solvent system, provide better dissolution ability and reaction environment, and contribute to the uniform formation of the isocyanate prepolymer. Secondly, the stirring process ensures the full mixing of each component, avoids local concentration unevenness and the occurrence of side reactions, thereby improving the quality and stability of the prepolymer.

[0028] For the above-mentioned preparation method of a Chinese herbal medicine comfortable insole, it can be further set as follows: when preparing component C in step S3, it also includes putting phosphate ester and silane coupling agent into container B and stirring simultaneously.

[0029] With the above technical solution, the addition of phosphate ester can effectively shield the residual catalyst impurities in the polyol, improve the storage stability of the prepolymer, and prevent unnecessary chemical reactions from occurring during the storage of the prepolymer. The introduction of the silane coupling agent can enhance the adhesion between the prepolymer and the substrate, improve the mechanical properties and durability of the final product. The stirring process ensures the uniform distribution of the phosphate ester and the silane coupling agent in the system, avoiding problems such as too high or too low local concentration, thereby improving the overall quality and consistency of the prepolymer.

[0030] For the above-mentioned preparation method of a Chinese herbal medicine comfortable insole and the insole made by this method, it can be further set as follows: it includes a comfortable insole body and a dense wear-resistant layer attached to the surface of the comfortable insole body. The comfortable insole body is provided with a plurality of ventilation holes, and the ventilation holes are distributed in a gradient from small to large from the surface to the inside.

[0031] With the above technical solution, a number of ventilation holes are provided inside the insole, significantly improving the durability and comfort of the insole. The dense wear-resistant layer can effectively extend the service life of the insole, reducing daily wear and tear. The design of the ventilation holes ensures good ventilation performance, improving the comfort during wearing. The ventilation holes are distributed in a gradient from small to large from the surface to the inside, which helps to more effectively discharge moisture and heat, keep the inside of the shoe dry, and prevent the growth of bacteria.

[0032] The above-mentioned preparation method of a Chinese herbal medicine comfortable insole and the insole made by this method can be further set as: the surface pore diameter of the ventilation holes ranges from 0.2 to 0.3 millimeters.

[0033] With the above technical solution, the surface pore diameter of the ventilation holes is carefully controlled within the range of 0.2 to 0.3 millimeters, which can not only effectively promote air circulation, enhance the air exchange inside the insole, thus keeping the feet dry and comfortable, reducing the stuffy feeling and moisture accumulation caused by long-term wearing; at the same time, this pore diameter range can also effectively block fine particles from entering the inside of the insole, such as dust or tiny sand grains, maintaining the cleanliness and hygiene inside the insole.

[0034] The above-mentioned preparation method of a Chinese herbal medicine comfortable insole and the insole made by this method can be further set as: the internal pore diameter of the ventilation holes ranges from 0.6 to 0.7 millimeters

[0035] With the above technical solution, the larger internal pore diameter can more effectively promote air circulation, accelerate the gas exchange inside and outside the insole, thus significantly improving the ventilation performance, ensuring that the feet can still remain dry and comfortable during long-term wearing, effectively preventing sweating and odor. This pore diameter range can effectively balance the ventilation and structural strength while ensuring high-efficiency ventilation, ensuring that the insole maintains good durability and support while providing excellent comfort.

[0036] The beneficial effects of the present invention:

[0037] 1. By mixing the Chinese herbal medicine extract with polyether polyol to obtain component A, and then mixing component A with polyester polyol, surfactant, catalyst, and compatibilizer in container A, the problem of large color difference in products caused by directly using Chinese herbal medicine itself in traditional Chinese herbal medicine insoles is avoided. Even when preparing insoles of different colors, a stable color mixing effect can be achieved, ensuring that the color of the finished insoles is uniform.

[0038] 2. During the preparation process, antibacterial agents and odor preventives are added, making the prepared insoles have good antibacterial and odor prevention effects, effectively solving the problems of foot odor, athlete's foot, etc. caused by traditional insoles being prone to getting wet and bacteria growing after sweating, and further improving foot health.

[0039] 3. Through systematic technological steps, every step from raw material preparation to the production of finished insole is optimized in detail. For example, when preparing Component B, antibacterial agents, deodorants, pore-forming agents, and hardening agents are added to ensure the multifunctionality and excellent performance of the insole material. Meanwhile, by using a casting mold and compressed air to blow and burst mechanical bubbles, the uniformity of the foam and the overall quality of the insole are improved.

[0040] 4. The use of Chinese herbal medicine ingredients and polyurethane materials not only ensures the functionality and comfort of the insole but also avoids the potential harm to the human body caused by traditional chemical materials, with good environmental protection and safety.

[0041] 5. The surface of the herbal insole undergoes a secondary reaction to form a dense and wear-resistant layer. By forming a dense protective layer on the insole surface, it can effectively reduce wear and tear during daily use, extend the service life of the insole, and at the same time, it does not affect the pharmacological properties of the Chinese herbal medicine insole.
