Abstract

The invention belongs to the technical field of rubber, and particularly relates to polyethylene rubber and a processing method thereof. The polyethylene rubber comprises following raw materials by weight: 100 parts of hyper branched polyethylene, 50-80 parts of carbon black, 2-5 parts of a peroxide crosslinking agent, 0-6 parts of zinc oxide, 0-5 parts of a lubricant, 0.3-0.5 part of an accelerant, and 0-0.2 part of sulfur. Beneficial effects of the polyethylene rubber and the processing method thereof are that: the hyper branched polyethylene (HBPE) is sulfurized by utilization of a peroxide sulfurization system, has good mechanical performances through stress-strain performance tests, and has a characteristic of high elasticity of rubber. The processing method of the polyethylene rubber is totally different from preparation methods of chlorinated polyethylene rubber and chlorosulfonated polyethylene rubber at present. The polyethylene rubber and the processing method thereof break the limit that polyethylene can be only used for making plastic products, expand the application scope of the polyethylene, and largely increase the additional value of polyethylene homopolymers.

Description

technical field

[0001] The invention belongs to the technical field of rubber, and in particular relates to a polyethylene rubber and a processing method thereof. Background technique

[0002] Synthetic rubber is undoubtedly the earliest synthetic polymer developed. Among all synthetic polymers, synthetic rubber is the only material with high elasticity, and is widely used in industries such as automobiles, construction, machinery, electric power, information, aviation, pharmaceuticals, health and daily necessities. At present, the preparation of synthetic rubber usually requires diolefins (such as butadiene, isoprene or ethylidene norbornene) or special monomers (such as diisocyanate or dimethyldichlorosilane). The higher prices of these raw materials lead to high prices of synthetic rubber.

[0003] Ethylene is the simplest and cheapest monomer. With the development and utilization of shale gas, the source of ethylene will become more abundant and the price will become ...
