[0019] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of the present application.

[0020] Embodiment 1: Please refer to Figures 1-4 A high-elastic corrosion-resistant rubber belt comprises an inner layer 3, a middle layer 2 and an outer layer 1, the outer layer 1 comprises a wear-resistant layer 13, the inner side of the wear-resistant layer 13 is bonded with a protective layer 12, the inner side of the protective layer 12 is bonded with a reinforcing layer 11, the inner side of the reinforcing layer 11 is bonded with an adsorption layer 22 in the middle layer 2, the inner side of the adsorption layer 22 is bonded with a barrier layer 21, the barrier layer 21 covers the outer side of the inner layer 3, the inner layer 3 comprises an antioxidant layer 33, the inner side of the antioxidant layer 33 is bonded with a buffer layer 32, and the buffer layer 32 covers the surface of a high-elastic layer 31.

[0021] The material of the wear-resistant layer 13 is ethylene-propylene-diene rubber, the wear-resistant layer 13 is bonded with the protective layer 12 through a high-temperature-resistant adhesive, the material of the protective layer 12 is chloroprene rubber, and the reinforcing layer 11 on the inner side of the protective layer 12 is in a grid shape and is made of polyester fiber.

[0022] The adsorption layer 22 in the middle layer 2 is internally provided with activated carbon, and the barrier layer 21 bonded to the inner side of the adsorption layer 22 is made of polytetrafluoroethylene film.

[0023] The material of the high-elastic layer 31 in the inner layer 3 is natural rubber, the material of the buffer layer 32 covering the outer surface of the high-elastic layer 31 is sponge rubber, and the material of the antioxidant layer 33 is butyl rubber containing an antioxidant.

[0024] The top and the bottom of the inner layer 3 are provided with the middle layer 2 and the outer layer 1 which are symmetrical to each other downward.

[0025] Specifically, the whole rubber belt is sequentially composed of the high-elastic layer 31, the buffer layer 32, the antioxidant layer 33, the barrier layer 21, the adsorption layer 22, the reinforcing layer 11, the protective layer 12 and the wear-resistant layer 13 from inside to outside.

[0026] The high-elastic layer 31 is made of natural rubber, which has excellent elasticity and can provide the rubber belt with basic high elasticity. When subjected to stretching or repeated deformation, the molecular chain can freely stretch and shrink, effectively reducing the occurrence of elastic fatigue. Compared with traditional rubber belts, the high-elastic layer 31 can more stably maintain the elongation rate and ensure good recovery performance, thereby providing continuous and stable elastic support for the operation of related equipment, greatly improving the elastic stability of the rubber belt in a complex stress environment, ensuring long-term stable operation of the equipment and prolonging the service life of the equipment.

[0027] The material of the buffer layer 32 is sponge rubber. The sponge rubber is soft and has a porous structure. When the rubber belt is impacted by external force or complex stress, the buffer layer 32 can play its unique buffering characteristics, disperse and absorb part of the stress through its own deformation, avoid the high-elastic layer 31 directly bearing excessive impact force, further reduce the possibility of elastic fatigue, effectively protect the high-elastic layer 31, so that the high-elastic layer 31 can stably play the elastic role for a long time, and maintain the good elastic state of the rubber belt;

[0028] The antioxidant layer 33 is composed of butyl rubber containing an antioxidant. Rubber is prone to oxidation reaction with oxygen in the air during long-term use, resulting in hardening, brittleness and performance degradation. The antioxidant in the antioxidant layer 33 can capture free radicals generated in the oxidation process, inhibit the oxidation reaction, effectively delay the aging of the rubber, maintain the flexibility and other properties of the rubber, thereby prolonging the overall service life of the rubber belt;

[0029] The barrier layer 21 is a polytetrafluoroethylene film. Polytetrafluoroethylene has excellent chemical stability and hardly reacts with any chemical substances. In the face of various chemical media such as acid, alkali, salt solution and organic solvent, the barrier layer 21 can form a solid barrier to fundamentally cut off the contact path of the chemical medium and the inner layer 3 rubber, prevent the rubber from aging and performance degradation due to chemical corrosion, and significantly improve the service life of the rubber belt in corrosive environments;

[0030] The adsorption layer 22 internally adds activated carbon. Activated carbon has a rich microporous structure and a large specific surface area, and has strong adsorption capacity. The activated carbon in the adsorption layer 22 can adsorb the chemical substances that penetrate into the middle layer 2, and cooperates with the barrier layer 21 to comprehensively improve the corrosion resistance of the rubber belt;

[0031] The reinforcing layer 11 is in a grid shape and is made of polyester fiber. The polyester fiber has high strength and large modulus, and the grid structure significantly enhances the overall strength and toughness of the rubber belt. When the rubber belt is subjected to external friction, collision and other mechanical actions, the reinforcing layer 11 can effectively disperse stress, prevent cracks and peeling on the surface of the rubber belt, effectively protect the internal structure, and ensure that the sealing and connecting functions of the rubber belt are not affected;

[0032] The protective layer 12 is made of chloroprene rubber, which has good weather resistance, ozone resistance and certain chemical corrosion resistance. It is adhered to the outside of the reinforcing layer 11, can protect the reinforcing layer 11, reduce the erosion of external environmental factors on the reinforcing layer 11, and maintain the structural stability and performance of the reinforcing layer 11;

[0033] The wear-resistant layer 13 is made of ethylene-propylene-diene rubber, which has good wear resistance, is bonded to the protective layer 12 by adding a high-temperature-resistant adhesive, and is specially treated. In actual use, the wear-resistant layer 13 can effectively resist friction from external objects, reduce the wear of the surface of the rubber belt, maintain the integrity of the rubber belt, and further improve the overall service life and reliability of the rubber belt.

[0034] Working principle: The wear-resistant layer 13 is located at the outermost side, and resists external friction and reduces the wear of the surface of the rubber belt by virtue of its special material and surface design. The protective layer 12 protects the reinforcing layer 11 and reduces the erosion of the reinforcing layer 11 by external environmental factors. The reinforcing layer 11 is in a grid shape, disperses stress, enhances the overall strength and toughness of the rubber belt, prevents cracks and peeling on the surface due to mechanical action, and thus protects the internal structure to ensure that the sealing and connecting functions of the rubber belt are not affected.

[0035] The barrier layer 21 uses its chemical stability to build a barrier to prevent chemical media such as acid, base, salt solution, and organic solvent from contacting the inner layer 3 rubber. The adsorption layer 22 adsorbs the chemical substances permeated from the outer layer 1, fixes the chemical substances on the surface by virtue of a large specific surface area and adsorption activity, and cooperates with the barrier layer 21 to improve the corrosion resistance of the rubber belt.

[0036] The high-elasticity layer 31 provides basic elastic support for the rubber belt when stretched or repeatedly deformed by virtue of its good elastic properties, reducing elastic fatigue. The buffer layer 32 protects the high-elasticity layer 31 by dispersing and absorbing stress, reducing the probability of elastic fatigue. The antioxidant layer 33 captures free radicals generated during the oxidation of rubber, inhibits the oxidation reaction, maintains the flexibility and other properties of the rubber, and prolongs the overall service life of the rubber belt.

[0037] The above shows and describes the basic principles and main features of the present application and the advantages of the present application. For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present application.
