[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The multi-layer structure of the present invention can effectively prevent the penetration of water. The multi-layer structure includes a base bonding layer directly in contact with the base ground, an intermediate functional layer that plays a connecting role, and an outermost wear-resistant and anti-skid surface layer that directly contacts the outside world. The intermediate functional layer is composed of a waterproof reinforcement layer, a buffer performance layer, and an enhanced physical performance layer to ensure that the waterproof reinforcement layer is well bonded to the other layers to avoid gaps that lead to water leakage. Each layer is prepared from a composite rubber material, which combines the advantages of various rubber materials. A layer of nano-silicon dioxide is coated on the surface of the circular floating point to form a microscopic hydrophobic structure on the surface of the circular floating point. Even in a wet state, a high friction coefficient can be maintained, so that the coiled material can still maintain its original wear resistance, waterproofness and anti-skid properties when used in a high temperature or humid environment.

[0016] 2. The present invention adopts natural rubber, silicone rubber and chloroprene rubber to blend into the wear-resistant and anti-skid layer, which effectively combines the advantages of each, improves the wear resistance of the wear-resistant and anti-skid layer, and reduces the wear rate. Natural rubber has good elasticity and tensile strength, can provide a certain resilience when rubbed, and reduce wear. Silicone rubber has excellent high temperature resistance and chemical corrosion resistance, and can maintain good stability in complex friction environments. The wear resistance of chloroprene rubber itself is also relatively outstanding, and the chlorine atoms in its molecular structure give it certain oil resistance and solvent resistance. It performs well in friction scenarios where it may contact chemical substances, so that the wear-resistant and anti-skid layer directly in contact with the outside world can be used in different climatic conditions and chemical environments, which broadens the application range of the coiled material.

[0017] 3. The present invention performs a vulcanization treatment on the whole after laminating the layers, optimizes the cross-linking structure of the rubber by changing the vulcanization system, and adopts a high-efficiency combination of vulcanizer and accelerator to make the rubber form a more stable three-dimensional network structure after vulcanization, so as to further enhance the bonding force between the layers and ensure the overall quality of the coil.

[0018] 4. The present invention improves the performance of the rubber itself by modifying the natural rubber, silicone rubber and chloroprene rubber in the raw materials, and adopts nanomaterials to blend with natural rubber to enhance the wear resistance of the rubber, and to a certain extent, improve the anti-aging performance of the rubber, because the nanoparticles can absorb and disperse ultraviolet rays, reduce the damage of ultraviolet rays to the rubber molecular chain, and introduce grafted monomers into the silicone rubber molecular chain to improve the compatibility of the silicone rubber, so that it can be better combined with other rubbers in the subsequent blending, thereby improving the performance of the entire rubber system, and further improving the flame retardancy of silicone rubber and chloroprene rubber. When a fire occurs, on the one hand, the coil can form a stable carbon layer to prevent the spread of the flame, and on the other hand, the inorganic flame retardant therein decomposes and absorbs heat at high temperature, releases water vapor, plays a role in cooling and diluting the combustible gas, and further prevents the spread of the fire.
