Abstract

The invention discloses a heat-resistant and cold-resistant acrylate rubber material which is prepared from the following components in parts by weight: 50-60 parts of acrylate rubber, 30-35 parts ofsilicone rubber, 2-8 parts of an ethylene-vinyl acetate copolymer, 6-12 parts of zinc monomethacrylate, 1-5 parts of a sulfur aid, 1-6 parts of a flame retardant, 2-5 parts of an environmental-friendly plasticizer, 3-7 parts of a attapulgite compound, 1-4 parts of an antiager, 1-4 parts of paraffin, 1-5 parts of hydroxyl silicone oil, 1-5 parts of a compatilizer, 1-4 parts of graphene and 1-2 parts of an organic amine activator. By adding a certain amount of silicone rubber, heat resistance and cold resistance of acrylic rubber can be improved obviously, so that high-temperature and low-temperature resistance and oil resistance are balanced. By adding the zinc monomethacrylate, the acrylate rubber has a relatively good mechanical property. By adding the plasticizer BXA-R, the acrylate rubber is optimal in comprehensive performance.

Description

technical field [0001] The invention relates to the field of rubber, in particular to a heat-resistant and cold-resistant acrylate rubber material. Background technique [0002] Raw rubber is the main material for the manufacture of rubber products. Rubber is an elastic polymer. According to the different ways of making it, rubber can be divided into two categories: synthetic rubber and natural rubber. Natural rubber mainly comes from the Hevea trilobata tree. When the skin of the rubber tree is cut open, milky white juice will flow out, which is called latex. The latex is condensed, washed, shaped, and dried to obtain natural rubber. Synthetic rubber is made by artificial synthesis, and different types of rubber can be synthesized by using different raw materials, such as butadiene rubber, neoprene rubber, styrene-butadiene rubber, nitrile rubber and so on. [0003] Acrylate rubber is an elastomer obtained by copolymerization of acrylate as the main monomer. Its main chai...
