Abstract

The invention belongs to the technical field of rubber and plastic products, and provides an ultralow-temperature-resistant rubber and plastic product. The product comprises, by mass, 20-25 parts of ethylene propylene diene monomer rubber. 3-5 parts of butyl rubber, 1-1.5 parts of butadiene rubber, 5-7 parts of a foaming agent, 20-30 parts of a flame retardant, 6-8 parts of operating oil, 4-7 parts of a low-temperature plasticizer, 0.3-0.5 part of an activator, 0.1-0.3 part of stearic acid, 3-5 parts of protective wax, 3-5 parts of an accelerant, 0.5-0.8 part of a vulcanizing agent and 0.1-0.2part of pigment. The ethylene propylene diene monomer, the butyl rubber, the butadiene rubber, the foaming agent, the flame retardant, the pigment, the operating oil, the low-temperature plasticizer,the protective wax, the activator and the stearic acid are subjected to banburying, discharging, open milling, compound milling and storage for 22-26 h, the vulcanizing agent and the accelerant are added, and mixing, extrusion molding and vulcanization foaming are conducted to obtain the ultralow-temperature-resistant rubber and plastic product. Through the technical scheme, the problem of poor low-temperature resistance of rubber in the prior art is solved.

Description

technical field [0001] The invention belongs to the technical field of rubber and plastic products, and relates to an ultra-low temperature resistant rubber and plastic product and a preparation method thereof. Background technique [0002] The rubber industry is an important part of my country's chemical industry and is a highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under a small external force, and can return to its original shape after the external force is removed. Its glass transition temperature (Tg) is low, and its molecular weight is often large, greater than hundreds of thousands. It not only provides people with daily-use, medical and other light industrial rubber products that are indispensable in daily life, but also plays an indispensable role in heavy and emerging industries such as transportation, construction, machinery and electronics. Due to the poor low temperature resistanc...
