Abstract

The invention discloses a high-temperature-resistant low-compression-set chloroprene rubber composition. The chloroprene rubber composition comprises the following components in parts by weight: 92-113 parts of chloroprene rubber, 10-50 parts of fast extruding furnace black, 20-80 parts of thermal cracking carbon black, 10-60 parts of light smoke method carbon black, 10-30 parts of a plasticizer, 2-7 parts of high-activity zinc oxide, 3-8 parts of high-activity magnesium oxide, 5-10 parts of an anti-aging agent, 1-4 parts of stearic acid, 0.5-2 parts of an accelerant and 0.5-2 parts of a vulcanizing agent. Meanwhile, the invention discloses a preparation method and preparation equipment of the formula; the obtained high-temperature-resistant low-compression-set CR rubber formula has excellent high-temperature compression deformation resistance, and the problems that automobile accessories such as automobile rubber tubes are not resistant to high temperature and poor in compression performance in the driving process are solved; and the high-temperature-resistant low-compression-set chloroprene rubber composition has good processing fluidity, can be conveniently processed, and is low in production cost, good in flame-retardant effect, not prone to combustion, good in high temperature resistance, long in service life and safer and more reliable to use. The method is suitable for the technical field of rubber production processes.

Description

technical field [0001] The invention belongs to the technical field of rubber production technology, and in particular relates to a neoprene rubber composition resistant to high temperature and low compression set, a preparation method and special preparation equipment. Background technique [0002] Chloroprene (CR) rubber is polymerized from chloroprene. It is a kind of synthetic rubber. It has self-reinforcement, high tensile strength, aging resistance, ozone resistance, fatigue resistance and good flame retardancy. It can be widely used in automobile parts, wire and cable sheaths, building materials, adhesives and other fields. [0003] Compression set is one of the important properties of vulcanized rubber, and its value is related to the elasticity and recovery of vulcanized rubber. The factors affecting the recovery ability mainly include the force between rubber molecules, the change or destruction of the network structure, and the displacement between molecules. Un...
