Description

Technical Field

[0001] The present invention relates to the technical field of insole manufacturing, and particularly relates to a manufacturing process of a Chinese herbal medicine color paste insole and the insole thereof. Background Art

[0002] Insoles not only improve 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, prevent foot fatigue and pain. At the same time, insoles made of antibacterial materials can also inhibit the growth of bacteria, reduce odors, and keep the environment inside the shoes 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, and utilize 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 formed insole color blocks to be dispersed, affecting the appearance and functions. In addition, due to the original 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 of Chinese herbal medicine insoles. This process synchronously realizes color adjustment and molding processing by introducing a pre-prepared Chinese herbal medicine color paste mother liquor into a polyurethane foam precursor solution, solving the previous incompatibility and color block dispersion problems; at the same time, this process solves the problem of large color differences in insoles by pre-adjusting the color of the Chinese herbal medicine color paste mother liquor. This method not only improves the health care effects such as antibacterial and odor-proof of Chinese herbal medicine insoles but also ensures the appearance 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 color paste insole in view of the deficiencies of the above prior art.

[0006] S1. Prepare polyol mixture component A containing Chinese herbal medicine color paste: Put the Chinese herbal medicine color paste mother liquor, polyester polyol, surfactant, catalyst, and compatibilizer into container A, stir, and heat and stir 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 isocyanate prepolymer component B: Pour diphenylmethane diisocyanate into container B for heating and standby to obtain component B, where the heating temperature is 40 - 50°C; S2. Mix the polyol mixture component A obtained in step S1 evenly with the isocyanate prepolymer component B to obtain a base material mixture component. S3. Pour the base material mixture component obtained in step S2 into a mold, then blow the mechanical bubbles with compressed air, close the mold and cure for 30 - 40 minutes to obtain a Chinese herbal medicine insole. With the above technical solution, by adding the Chinese herbal medicine color paste masterbatch to the polyol mixture component 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 the uniformity of the insole colors within the same batch of finished products and the color difference between different batches. At the same time, the problem of incompatibility between Chinese herbal medicine and polyether is significantly solved, avoiding the phenomenon of color block dispersion in the molded insoles, and improving the overall aesthetics and functionality of the insoles. Polyether polyol is mainly used to improve the elasticity and comfort of the insole. 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, thereby improving 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, 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 molding process. It can accelerate the cross-linking reaction between polymer molecules, promote the curing and molding of materials. And diphenylmethane diisocyanate in component B, during the molding 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 foam formation, and at the same time can also control parameters such as the density and pore size of the foam, promoting the foaming and molding of the insole.

[0007] The above manufacturing process of a Chinese herbal medicine color paste insole can be further set as follows: The Chinese herbal medicine color paste process includes the following steps: S1.1. Prepare basic Chinese medicinal materials: Scutellaria baicalensis, Angelica dahurica, Glycyrrhiza uralensis, Angelica sinensis. S1.2. Use a Chinese medicine grinder or mortar to grind Scutellaria baicalensis, Angelica dahurica, Glycyrrhiza uralensis, and Angelica sinensis into fine powders respectively. Screen the ground herbal powders through a fine mesh sieve to remove incompletely ground particles and impurities, and obtain pure herbal powders.

[0008] S1.3. Put the screened herbal powders into a pot, add water, and boil over fire until the active ingredients of the herbs are fully dissolved in the water to form a thick medicinal juice. Filter the boiled herbal juice with a filter cloth or gauze to remove the remaining medicinal residues.

[0009] S1.4. Secondarily heat the filtered medicinal juice to further evaporate the water until the medicinal juice becomes thick and nearly paste-like, forming a uniform Chinese herbal medicine color paste.

[0010] With the above technical solution, by carefully selecting Chinese medicinal materials such as Scutellaria baicalensis, Angelica dahurica, Glycyrrhiza glabra, and Angelica sinensis, and adopting a multi-step process of grinding, screening, boiling, filtering, and secondary heating evaporation, the purity of the color paste and the full utilization of active ingredients are ensured, the potential hazards of traditional chemical dyes to the environment and human body are avoided, and the color paste is also given good dyeing effects and stability. The natural characteristics of Chinese herbal medicines make the color paste may have a faint herbal aroma during the dyeing process, enhancing the quality and added value of textiles.

[0011] The above manufacturing process of a Chinese herbal medicine color paste insole can be further set as follows: when preparing component A of the polyol mixture containing the Chinese herbal medicine color paste in step S1, an antibacterial agent and an anti-odor agent are also put into container A and stirred simultaneously.

[0012] With 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 anti-odor agent can be activated carbon that can adsorb and eliminate or reduce the odor in the insole and keep the inside of the shoe fresh and hygienic. The antibacterial agent and the anti-odor agent are directly formed in the polyurethane elastomer insole, enabling it to achieve an efficient antibacterial and deodorant effect after contacting the sole of the foot.

[0013] The above manufacturing process of a Chinese herbal medicine color paste insole can be further set as follows: when preparing component A of the polyol mixture in step S1, a pore-forming agent and a hardening agent are also put into container A and stirred simultaneously.

[0014] 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 non-Chinese herbal medicine insole has elasticity and comfort while having a certain degree of abrasion resistance. The pore-forming 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 above manufacturing process of a Chinese herbal medicine color paste insole can be further set as follows: perform a painting process on the surface of the Chinese herbal medicine insole obtained in step S3 to form a paint layer on the surface of the Chinese herbal medicine insole, obtaining a boneless Chinese herbal medicine insole.

[0016] By adopting the above technical scheme, the painting process is used to paint the surface of the formed Chinese herbal insole, which can form a protective film on the surface of the insole to play an isolating role, making the insole not easily damaged by external factors such as wear, stains, moisture, etc., so that it can replace the original artificial leather, making the insole wear-resistant while reducing costs, improving air permeability, and extending the service life of the insole. At the same time, color, pattern and texture are added to the surface of the insole to make the insole more beautiful and personalized, and it can directly contact the sole of the foot, and the antibacterial and deodorizing material added in the subsequent process can be applied to the sole of the foot to improve the deodorizing and sterilizing effect. In addition, since it replaces the original artificial leather that cannot be stretched and extended, the contact surfaces between the sole of the foot and the sole of the shoe have extendable treading points, that is, each point on the sole of the foot or the toes can make the insole stretched and deformed under force and then reset when force is applied, which greatly improves the stability and comfort of foot wearing.

[0017] The above-mentioned process for making a Chinese herbal medicine color paste insole can be further configured as follows: the painting process comprises the following steps: S3.1. Apply a layer of primer on the surface of the Chinese herbal insole obtained in step S3; S3.2, using a brush, roller or spray gun, apply the insole topcoat prepared in step S3.1 onto the primer surface of the polyurethane insole to obtain a boneless Chinese herbal insole; S3.3, drying the Chinese herbal insoles in step S3.2 naturally or using a curing device.

[0018] By adopting the above technical scheme, the diluent is mainly used to reduce the viscosity of the topcoat, improve the process performance and assist the construction of the topcoat. At the same time, the diluent can penetrate into the topcoat, increase the smoothness and uniformity of the topcoat, improve the decorative effect and performance of the topcoat, keep the painted surface clean and smooth, improve the foot feel, reduce surface viscosity, and avoid the insole being removed when slipping. The primer is used to fill the tiny gaps and unevenness on the surface of the insole, provide a smooth base, and increase the adhesion of the topcoat. The topcoat is used to decorate and protect the surface of the insole, and ensure good aesthetics and durability while ensuring air permeability. The main function of drying is to volatilize the solvents in the primer and topcoat, and promote the coating to dry and form a film. By drying, the thickness and uniformity of the coating can be controlled to avoid the coating being too thick or too thin, affecting the final coating effect.

[0019] The above-mentioned production process of the Chinese herbal medicine color paste insole can be further configured as follows: the primer in step S3.1 is an acrylic primer or a polyurethane primer, the topcoat is a polyurethane topcoat or an acrylic topcoat, and the diluent is a nitro acid diluent or a peroxide paint diluent.

[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 anti-corrosion performance. 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 closely combine with the surface of the polyurethane sole to form a solid 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 insole made by the above-mentioned production process of a Chinese herbal medicine color paste 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 adding the Chinese herbal medicine color paste mother liquor to the polyol mixture component A, the problem of large color difference in products caused by directly using Chinese herbal medicines themselves 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 colors of the finished insoles are uniform. 2. During the preparation process, antibacterial agents and anti-odor agents are added, making the prepared insoles have good antibacterial and anti-odor effects, effectively solving the problems of foot odor, athlete's foot, etc. caused by traditional insoles being prone to dampness and bacterial growth after sweating, and further improving foot health.

[0024] 3. Through a systematic process, from raw material preparation to the production of finished insoles, each step has been optimized in detail. For example, when preparing component A, antibacterial agents, anti-odor agents, hole-opening agents, and hardening agents are added to ensure the multifunctionality and excellent performance of the insole material. At the same time, by using a casting mold and blowing mechanical bubbles with compressed air, the uniformity of the foam and the overall quality of the insole are improved.

[0025] 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, and has good environmental protection and safety.
