Description

Technical Field

[0001] This utility model relates to the field of insole manufacturing technology, and specifically relates to a manufacturing process of a Chinese herbal medicine insole and the insole. 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, thereby 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 themselves, 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. 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 solves the previous incompatibility and color block dispersion problems by first producing antibacterial and odor-proof polyurethane foam and then performing a molding process. At the same time, by pre-soaking the Chinese herbal medicines to stabilize their color numbers, the problem of large color differences in the 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, and has broad application prospects. Summary of the Invention

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

[0006] 1. To achieve the above object, the present invention provides the following technical solution. A manufacturing process of a Chinese herbal medicine insole is characterized by including the following steps: S1. Pre-soak Chinese herbal medicines in water for several hours, dilute them until the color numbers of the Chinese herbal medicines are stable to ensure the stability of subsequent color adjustment, and grind the Chinese herbal medicines and polyether polyol into powder to obtain a mixture A; S2. Prepare Component A: Put the A mixture prepared in S1, polyester polyol, surfactant, catalyst, and compatibilizer into Container A, stir, and heat with stirring for standby. 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; Prepare Component B: Pour diphenylmethane diisocyanate into Container B and heat for standby to obtain Component B, where the heating temperature is 40 - 50°C; S3. Mix Component A obtained in step S1 and Component B evenly to obtain the base material mixed component; S4. Pour the base material mixed component obtained in step S2 into a mold, then blow the mechanical bubbles with compressed air, close the mold and cure for 30 - 40 min to obtain the Chinese herbal medicine insole; With the above technical solution, by pre - soaking Chinese herbal medicines in water, their color numbers are stabilized, avoiding the problem of large color differences in products caused by the original colors of Chinese herbal medicines in traditional Chinese herbal medicine insoles. In this way, when preparing insoles of different colors subsequently, a stable color - mixing effect can be achieved, ensuring that the colors of the finished insoles are uniform. Grinding Chinese herbal medicines and polyethers into powder and then adding a compatibilizer to mix significantly solves the problem of incompatibility between Chinese herbal medicines and polyethers, avoiding the phenomenon of color block dispersion in the formed insoles, and 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, improves the integrity and stability of the insole, increases the density of the insole, and thus improves the durability and wear resistance of the insole. The surfactant mainly plays the roles of wetting and emulsifying during the insole forming process, can reduce the interfacial tension, 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 A, helping to mix various materials evenly during the preparation of Component A. The catalyst plays a role in promoting chemical reactions during the insole forming process. It can accelerate the cross - linking reaction between polymer molecules and promote the curing and forming of materials. And diphenylmethane diisocyanate in Component B, during the forming in step S3, by reacting with components such as polyester polyol and polyether polyol, can increase the cross - linking density of the insole material, improve the elasticity and durability of the insole, can promote the formation of foam, and at the same time can also control parameters such as the density and pore size of the foam, promoting the foaming and forming of the insole.

[0007] The above - mentioned manufacturing process of a Chinese herbal medicine insole and the insole can be further set as: The pre - soaking time of the Chinese herbal medicines in water is 48 hours.

[0008] With the above technical solution, by pre - soaking Chinese herbal medicines in water for 48 hours, their color numbers are stabilized, avoiding the problem of large color differences in products caused by the original colors of Chinese herbal medicines in traditional Chinese herbal medicine insoles.

[0009] The manufacturing process of the above-mentioned Chinese herbal medicine insole and the insole can be further set as follows: The Chinese herbal medicines are Carex meyeriana Kunth, Artemisia argyi Levl. & Van., and Syzygium aromaticum (L.) Merr. & Perry.

[0010] Adopting the above technical solution, Carex meyeriana Kunth has the functions of removing dampness and deodorizing, antibacterial and mildew-proof, and can effectively improve the foot environment; Artemisia argyi Levl. & Van. can, with its characteristics of warming the meridians and dispelling cold, promoting blood circulation and relieving pain, help relieve foot fatigue and pain; Syzygium aromaticum (L.) Merr. & Perry has the effects of anti-inflammatory and bactericidal, and purifying the air, and can prevent athlete's foot and odor. The insole made by combining the three can not only provide a comfortable foot feeling, but also effectively protect foot health, and is an ideal natural health care material.

[0011] The manufacturing process of the above-mentioned Chinese herbal medicine insole and the insole can be further set as follows: When preparing component A in step S1, it further includes putting an antibacterial agent and an odor preventive agent into container A and stirring simultaneously.

[0012] Adopting the above technical solution, the antibacterial agent can be a nano-silver antibacterial agent that can effectively inhibit the growth of bacteria by destroying the bacterial cell membrane and inhibiting the activity of bacterial respiratory enzymes, and keep the insole clean and hygienic. The odor preventive agent can be activated carbon that can adsorb properties to eliminate or reduce the odor in the insole and keep the inside of the shoe fresh and hygienic. The antibacterial agent and the odor preventive agent are directly formed in the polyurethane elastomer insole, so that it can achieve an efficient antibacterial and deodorizing effect after contacting the sole of the foot.

[0013] The manufacturing process of the above-mentioned Chinese herbal medicine insole and the insole can be further set as follows: When preparing component A in step S1, it further includes putting a blowing agent and a hardening agent into container A and stirring simultaneously.

[0014] Adopting the above technical solution, the function of the blowing 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 function of the hardening agent is to harden the insole and increase its durability and abrasion resistance. By adding the hardening agent, the insole can be more wear-resistant and wrinkle-resistant, and its service life can be extended. By controlling the components of the blowing agent and the hardening agent, the boneless polyurethane antibacterial and deodorizing insole has the characteristics of elasticity and comfort while having wear-resistant characteristics, improves the service life of the product, and can achieve the characteristics of wear resistance and pressure resistance without an artificial leather-like wear-resistant layer. The blowing agent can be aerogel with a porous structure to improve the air permeability and moisture absorption of the insole, and the hardening agent can be polyurethane resin to improve the durability and abrasion resistance of the insole.

[0015] The manufacturing process of the above-mentioned Chinese herbal medicine insole and the insole can be further set as follows: The surface of the Chinese herbal medicine insole obtained in step S4 is subjected to a painting process to form a paint layer on the surface of the Chinese herbal medicine insole, and a boneless Chinese herbal medicine insole is obtained.

[0016] With the above technical solution, the painting process is used to coat the surface of the formed Chinese herbal medicine insole with paint, which can form a protective film on the insole surface, playing an isolation role, making the insole not easily damaged by external factors such as abrasion, stains, and moisture. It replaces the original artificial leather, making the insole wear-resistant while reducing costs, improving breathability, extending the service life of the insole, increasing the friction on the insole surface, preventing the sole from slipping, improving the stability and comfort of wearing, adding colors, patterns, and textures to the insole surface, making the insole more beautiful and personalized, and being able to directly contact the sole, enabling the antibacterial and odor-proof materials added in the subsequent process to act on the sole, improving the deodorization and bactericidal effect. And because it replaces the artificial leather that could not be stretched, each contact surface between the sole and the shoe sole has extendable stepping points, that is, when each point on the sole or toes exerts force, the insole can be stressed and extended and then reset, greatly improving the stability and comfort of foot wearing.

[0017] The above-mentioned manufacturing process of a Chinese herbal medicine insole and the insole can be further set as follows: The painting process in step S4 includes the following steps: S4.1: Brush a layer of primer on the surface of the Chinese herbal medicine insole obtained in step S4; S4.2: Use a brush, roller or spray gun to apply the insole topcoat prepared in step S4.1 on the primer surface of the polyurethane insole to obtain a boneless Chinese herbal medicine insole; S4.3: Naturally dry the Chinese herbal medicine insole in step S4.2 or dry it through a curing device.

[0018] With the above technical solution, the thinner is mainly used to reduce the viscosity of the topcoat, improve the process performance and assist in the construction of the topcoat. At the same time, the thinner can penetrate into the topcoat, increase the smoothness and uniformity of the topcoat, improve the decorative effect and service performance of the topcoat, keep the painted surface clean and smooth, enhance the foot feeling, reduce the surface stickiness, and avoid taking the insole away when taking off the shoes. The primer is used to fill the tiny gaps and unevenness on the insole surface, provide a smooth base, and increase the adhesion of the topcoat. The topcoat is used to decorate and protect the insole surface, and while ensuring breathability, it has good aesthetics and durability. The role of drying is mainly to volatilize the solvents in the primer and topcoat, promoting the coating to dry and form a film. Through drying, the thickness and uniformity of the coating can be controlled, avoiding the coating being too thick or too thin and affecting the final painting effect.

[0019] The above-mentioned manufacturing process of a Chinese herbal medicine insole and the insole can be further set as follows: The primer in step S4.1 is acrylic primer or polyurethane primer, the topcoat is polyurethane topcoat or acrylic topcoat, and the thinner is nitro acid thinner or peroxyethylene paint thinner.

[0020] With the above technical solution, the nitro acid thinner is a thinner prepared from organic solvents such as esters and alcohols, which has the characteristics of good solubility, moderate volatility, and fast drying speed. It can be well incorporated into the topcoat. The peroxyethylene paint thinner is prepared from organic solvents such as acetate, acetone, and benzene. The acrylic primer has strong adhesion, good weather resistance, and strong corrosion resistance. It can also play a role in sealing and protecting the insole, effectively preventing the base material from getting damp and mildewing, and providing a good adhesion foundation for the subsequent topcoat. The polyurethane primer has excellent adhesion and durability. It can be closely combined with the surface of the polyurethane sole to form a strong protective layer. It also has good scratch resistance and wear resistance, and can effectively resist the friction and pressure suffered by the insole during use. The polyurethane topcoat has the characteristics of full color, good decoration, wear resistance, and weather resistance, providing the required appearance effect on the surface of the insole. At the same time, it can also increase the durability and scratch resistance of the insole. It has a fast drying speed, strong adhesion, is not easy to fall off, and can permanently maintain the beauty of the insole surface. The acrylic topcoat is fast drying and hard, has good gloss and color stability, good weather resistance and scratch resistance, and can maintain the beauty and durability of the insole.

[0021] The above-mentioned manufacturing process of a Chinese herbal medicine insole and the insole can be further set as: including a Chinese herbal medicine elastic main body, a topcoat layer attached to the Chinese herbal medicine elastic main body, and a primer layer provided between the topcoat layer and the Chinese herbal medicine elastic main body.

[0022] With the above technical solution, by setting a primer layer and a topcoat layer on the Chinese herbal medicine elastic main body, the primer layer increases the adhesion of the topcoat, and the topcoat layer is used to reduce the stickiness of the Chinese herbal medicine elastic main body and improve the surface smoothness.

[0023] The beneficial effects of the present invention: 1. By grinding Chinese herbal medicine and polyether into powder and then adding a compatibilizer, the problem of incompatibility between Chinese herbal medicine and polyether is significantly solved, avoiding the phenomenon of color block dispersion in the formed insole, and improving the overall aesthetics and functionality of the insole.

[0024] 2. By pre-soaking Chinese herbal medicine in water for 48 hours to stabilize its color number, the problem of large color difference in products caused by the original color of traditional Chinese herbal medicine insoles is avoided. In this way, when preparing insoles of different colors subsequently, a stable color mixing effect can be achieved, ensuring that the colors of the finished insoles are uniform.

[0025] 3. During the preparation process, antibacterial agents and deodorants are added, making the prepared insole have good antibacterial and deodorant effects, effectively solving the problems of foot odor, athlete's foot, etc. caused by traditional insoles being prone to getting damp and bacterial growth after sweating, and further improving foot health.

[0026] 4. By first producing antibacterial and odor - preventing polyurethane foam and then putting it into a shaping mold for surface treatment and shaping, the prepared insole not only has good elasticity and cushioning, is comfortable to wear, but also forms a paint layer on the insole surface through the painting process, improving the aesthetics and durability of the insole.

[0027] 5. Through a systematic process step, from raw material preparation to the production of the finished insole, each step has been optimized in detail. For example, when preparing component A, antibacterial agents, odor - preventing agents, blowing agents, and hardeners are added to ensure the multifunctionality and excellent performance of the insole material. At the same time, by using a casting mold and compressed air to burst mechanical bubbles, the uniformity of the foam and the overall quality of the insole are improved.

[0028] 6. Using Chinese herbal medicine ingredients and polyurethane materials not only ensures the functionality and comfort of the insole but also avoids the problem that traditional chemical materials may be harmful to the human body, having good environmental protection and safety.
