Problems solved by technology

However, the relatively poor physical and mechanical properties of ethylene-propylene rubber under the peroxide-based vulcanization system have not been significantly improved. Therefore, there is still a need and room for further improvement in the physical and mechanical properties of rubber products that use the two together.
[0005] Therefore, for applications that require high physical and mechanical properties, in order not to affect the use effect and reduce costs, often only less ethylene-propylene rubber can be used together, which cannot further improve the aging resistance of the product
On the other hand, for occasions that require high aging resistance, in order not to affect the use effect, only a small amount of natural rubber can be used together, which cannot further improve the physical and mechanical properties and bonding properties of the rubber compound.

Abstract

The invention discloses a rubber composition and a processing method, as well as a product using the rubber composition and a production method. A rubber composition includes: a rubber matrix, a reinforcing filler and a crosslinking agent. The 100 parts by weight The rubber matrix includes: 1-99 parts of branched polyethylene, 0-90 parts of ethylene-propylene rubber, and 1-95 parts of isoprene elastomer. The beneficial effect is that the rubber composition has good aging resistance, physical and mechanical properties and compression set resistance, and can be used to produce rubber products such as rubber bearings, tires, rubber hoses, and conveyor belts.

Description

technical field [0001] The invention belongs to the field of rubber, and specifically relates to a rubber composition and a processing method thereof. The invention also relates to the application of the rubber composition and a method for producing the rubber product. Background technique [0002] Isoprene-based elastomers mainly include natural rubber and synthetic isoprene rubber, accounting for the highest consumption proportion in the overall rubber raw materials. Especially natural rubber is widely used in tires, hoses, tapes, rubber rollers, shoe soles, Gloves, shock absorbers and other rubber products. However, although natural rubber has many of the above-mentioned excellent properties, due to its high degree of unsaturation, the aging resistance of its products is poor. [0003] Ethylene-propylene rubber has excellent aging resistance due to its highly saturated molecular structure, and is widely used in occasions where aging resistance is required. However, due ...
