[0002] In the fields of industry, construction, logistics, etc., workers face a variety of dangerous environments and often need to walk and work on slippery, greasy, rough or unstable surfaces. These environmental conditions not only increase the difficulty of work, but also bring the risk of accidental injuries such as slips and falls. Therefore, it is very important to provide high-performance anti-slip protection measures. Anti-slip labor shoes play an important role in ensuring the safety of workers and can effectively reduce the probability of slip accidents.

[0003] In practice, with the diversification of construction site conditions, traditional anti-slip shoes can hardly fully meet the special needs of these environments. Water and oil in slippery environments can easily reduce the friction of the soles, resulting in reduced anti-slip effects. Especially in fields such as chemical and food processing, the ground may be adhered to grease, chemicals or other pollutants, increasing the risk of slipping. With the diversification of working environments, the anti-slip effect of single-structure soles in complex terrains and harsh conditions is not ideal, especially on wet or oily ground. In addition, the sole material is prone to aging and wear under high-frequency use, resulting in a weakened anti-slip effect, which cannot guarantee the safety of users for a long time. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a special anti-slip labor protection shoe, which solves the problem that traditional anti-slip shoes are difficult to meet the needs. The accumulated water and oil in the wet and slippery environment will reduce the friction of the sole. Especially in the fields of chemical industry and food processing, the grease and chemicals on the ground increase the risk of slipping and the transmission labor protection shoe sole structure is relatively single.

[0005] To achieve the above objectives, the present invention is implemented through the following technical scheme: a special anti-slip labor protection shoe, including a sole, an upper, a toe and an insole, the sole is composed of a multi-layer structure, the multi-layer structure includes a wear-resistant layer, a buffer layer, an anti-static layer, an anti-puncture bottom layer and an anti-slip layer arranged in sequence from top to bottom, the anti-slip layer is an oil-resistant rubber material, and the bottom end is provided with anti-slip patterns of various shapes, the wear-resistant layer is made of synthetic rubber, and the buffer layer is made of polyurethane.

[0006] Preferably, the surface of the anti-skid layer of the sole is provided with a texture in which tiny rubber protrusions are arranged alternately.

[0010] Preferably, the toe cap includes a steel protective layer, and the steel protective layer is made of steel material.

[0011] Preferably, the shoe upper comprises a composite fabric and a waterproof coating, and the exterior of the composite fabric is sprayed with a waterproof coating.

[0012] Preferably, a reflective logo is connected to the side of the upper.

[0014] Beneficial Effects The present invention provides a special anti-skid labor protection shoe and a production process thereof. Compared with the prior art, the present invention has the following beneficial effects: The present invention realizes good anti-skid, wear-resistant, anti-static, anti-puncture and adaptability in chemical corrosion environments through the design of the multi-layer sole and the application of specific materials, thereby ensuring the safety performance of the shoes under special working conditions.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1 - Figure 5 The present invention provides a technical solution, which specifically includes the following embodiments: Example: A special anti-skid labor shoe comprises a sole 2, an upper 1, a toe cap 7 and an insole. The sole 2 is composed of a multi-layer structure, which comprises a wear-resistant layer 203, a buffer layer 204, an antistatic layer 205, an anti-puncture bottom layer 202 and an anti-skid layer 201 arranged in sequence from top to bottom. The anti-skid layer 201 is made of oil-resistant rubber material, and anti-skid patterns 6 of various shapes are arranged at the bottom. The wear-resistant layer 203 is made of synthetic rubber, and the buffer layer 204 is made of polyurethane.

[0019] Preferably, the surface of the anti-slip layer 201 of the sole 2 is provided with a texture in which tiny rubber protrusions 5 are arranged alternately.

[0020] Among the above-mentioned components, the surface of the anti-slip layer 201 of the sole 2 is provided with alternatingly arranged tiny rubber bumps 5. This structure not only increases the friction when the sole 2 contacts the ground, but also forms a multi-directional anti-slip effect through bumps of different heights and shapes to adapt to the anti-slip requirements of different environments, thereby further improving the durability and adaptability of the sole 2.

[0021] Preferably, the material of the anti-slip layer 201 is treated with an acid- and alkali-resistant coating.

[0022] In the above-mentioned components, the anti-slip layer 201 material is treated with an acid- and alkali-resistant coating to enhance its durability in a chemically corrosive environment. During processing, the surface of the anti-slip layer 201 material is first cleaned to ensure the adhesion of the coating. Next, a layer of a base coating with strong adhesion is applied to firmly bond the coating to the anti-slip layer 201 material. Then, a highly corrosion-resistant protective layer, such as a fluororesin or polyurethane composite material, is evenly sprayed or coated on its surface to form acid- and alkali-resistant protection. The coating thickness can be adjusted according to usage requirements to adapt to protection requirements of different intensities, thereby ensuring that the sole 2 has excellent chemical corrosion resistance and anti-slip properties in a corrosive environment, thereby extending the service life and maintaining comfort and flexibility.

[0023] Preferably, the antistatic layer 205 is made of nylon conductive fibers.

[0024] Among the above components, high-quality nylon conductive fiber mesh is prepared through wire drawing and weaving processes, and is cut and molded according to the size of the sole 2 to ensure adaptability and conductivity. In order to enhance the conductive effect, a wear-resistant conductive coating can be sprayed on the surface of the fiber mesh. Subsequently, the antistatic layer 205 and the buffer layer 204 are compounded by hot pressing or adhesive, and the temperature and pressure are strictly controlled to ensure that the materials are firmly combined. After the initial compounding is completed, the antistatic performance test is carried out to confirm that the resistance value meets the standard. Finally, the antistatic layer 205 and the other layers of the sole 2 are integrally hot-pressed and the quality is inspected to ensure the conductivity and durability of the finished sole 2, which is suitable for static-sensitive working environments.

[0025] Preferably, the puncture-resistant bottom layer 202 is made of a high-strength fiber composite material.

[0026] Among the above components, the puncture-resistant midsole layer 202 is made of a high-strength fiber composite material and adopts a multi-layer structure design. The puncture-resistant effect is enhanced by cross-weaving and lamination processes. The material is aramid fiber, which has both high tensile strength and flexibility. The processing technology includes material cutting, lamination in a specific direction, hot pressing molding and quality inspection to ensure that the materials are firmly combined and have protective properties. After molding under high temperature and high pressure conditions, the product undergoes puncture resistance and wear resistance tests, and finally obtains a sole 2 structure that is lightweight, durable and suitable for use in high-risk environments.

[0027] Preferably, the toe cap 7 comprises a steel protective layer 3, and the steel protective layer 3 is made of steel material.

[0028] Among the above-mentioned components, the steel protective layer 3 is made of high-strength steel material to provide excellent impact resistance and compression resistance to protect the safety of the foot. The steel protective layer 3 is precisely processed to ensure that it fits tightly with the toe 7 structure and has moderate weight, which is suitable for long-term wear. The processing technology includes steel cutting, molding and polishing to make its appearance smooth and avoid burrs. Subsequently, the steel protective layer 3 and other materials of the toe 7 are fixed by high-temperature bonding or pressing process to ensure a firm combination, improve the durability and impact resistance of the toe 7, and meet the comfort and safety requirements.

[0029] Preferably, the shoe upper 1 comprises a composite fabric 101 and a waterproof coating 102 , and the waterproof coating 102 is sprayed on the outside of the composite fabric 101 .

[0030] Among the above components, the composite fabric 101 is made of high-performance materials that are wear-resistant and breathable, has good comfort and durability, and is suitable for long-term wearing. The waterproof coating 102 sprayed on the outside uses a high-efficiency waterproof material, such as a polyurethane or fluoride coating, which effectively prevents moisture penetration while maintaining the breathability of the fabric to ensure that the feet are dry. The composite fabric 101 is first cut into the shape of the upper 1, and then the waterproof coating 102 is evenly covered on the fabric surface through a spraying process, and the coating is fixed through a heat treatment or hot pressing process so that it is firmly combined with the fabric surface to form an upper 1 structure with excellent waterproof performance and breathability.

[0031] Preferably, a reflective mark 4 is connected to the side of the upper 1 .

[0032] Among the above components, a high-brightness reflective logo 4 is used to increase visibility at night or in low-light environments. The reflective logo 4 is cut and positioned, and is firmly bonded and fixed to the side of the upper 1 to ensure the durability and stability of the logo. It is suitable for environments requiring high visibility such as outdoors or construction sites.

[0033] Preferably, the method comprises the following steps: S1: preparing the material of the wear-resistant layer 203, selecting a high-strength rubber composite material, processing it into the basic shape of the sole 2, ensuring the accurate size of the wear-resistant layer 203 through a hot pressing process, and forming the upper structure of the sole 2, wherein the high-strength rubber composite material has excellent wear resistance, is suitable for the frequent contact of the sole 2 with the ground, and ensures the durability of the sole 2. In this step, the rubber material is processed into the preliminary shape of the sole 2 through an extrusion, calendering or injection molding process to ensure that it meets the design requirements of the sole 2, and then, the material is heated and pressurized using a hot pressing process to ensure the accurate size of the wear-resistant layer 203 and make its surface flat and free of bubbles. The hot pressing process can also improve the bonding strength of the wear-resistant layer 203 with other layers, and ensure its firmness on the upper layer of the sole 2; S2: preparing the material of the buffer layer 204, selecting an elastic polymer material with a porous structure, and after compression molding, firmly fixing it to the wear-resistant layer 203 through an adhesive, wherein the material of the buffer layer 204 is selected to be an elastic polymer material with a porous structure, such as polyurethane, which has good elasticity and cushioning properties, can effectively absorb external impact force, and reduce pressure on the foot. In this step, after selecting a suitable porous structure material, it is processed into a buffer layer 204 suitable for the size of the sole 2 through a compression molding process. Compression molding can ensure that the buffer layer 204 has a uniform density and pore structure, and enhance its buffering effect. The formed buffer layer 204 is firmly combined with the wear-resistant layer 203 through an adhesive to form the middle structure of the sole 2; S3: preparing the anti-skid layer 201, molding the oil-resistant rubber material into anti-skid patterns 6 with various shapes, including rubber protrusions 5, and combining with the buffer layer 204, wherein the anti-skid layer 201 is made of oil-resistant rubber material, which has good oil resistance and anti-skid performance, and molding the oil-resistant rubber into anti-skid patterns 6 with various shapes, so as to further improve the friction between the sole 2 and the ground. Through molding, the anti-skid patterns 6 can be evenly distributed on the contact surface of the sole 2, thereby enhancing the anti-skid effect of the sole 2. After molding, the anti-skid layer 201 and the buffer layer 204 are combined by a hot pressing process to ensure that they are firmly bonded and the anti-skid effect is long-lasting and stable; S4: preparing the material of the upper 1, selecting a wear-resistant, breathable and waterproof composite material fabric 101 fabric, forming the basic shape of the upper 1 by cutting and sewing, and applying sealing treatment at the seams of the upper 1, the composite material fabric 101 knitted from nylon and polyester fibers, through precision cutting and sewing processes, the upper 1 material is processed into the shape and size required by the upper 1, and during the sewing process, the seams are sealed by a sealing treatment process, such as heat sealing, to ensure that the seams of the upper 1 are water-proof and enhance the waterproof effect of the upper 1; S5: Perform waterproof treatment on the upper 1, spray waterproof coating 102 evenly on the surface of the upper 1, and use hot melt technology to make the waterproof coating 102 completely fit the surface of the composite fabric 101. Select high-quality waterproof coating 102 materials, such as polyurethane, and spray evenly on the surface of the upper 1. The coating material is evenly covered on the surface of the composite fabric 101 through the spraying process to form a waterproof protective layer. After that, the waterproof coating 102 is completely fitted to the surface of the composite fabric 101 through hot melt technology to ensure that the waterproof coating 102 has strong adhesion and will not fall off or peel off due to use. This process ensures the waterproofness and durability of the upper 1, and does not affect the breathability of the upper 1; S6: Install the reflective logo 4 on the side of the upper 1. Use high-brightness reflective logo 4 material and fix it through a bonding process. It can efficiently reflect the light source and increase the visibility of the shoes. During installation, accurately position the reflective logo 4 on the side of the upper 1, and then use a strong adhesive or hot-melt process to firmly fix it. The reflective logo 4 can be designed as a strip to ensure that it can effectively reflect light at multiple angles.
