Abstract

The invention relates to high-thermal conductivity and high-elasticity acrylate rubber which has good thermal conductivity, heat resistance and elasticity and can meet the needs of use as a gasket inhigh-temperature weight-bearing machinery. The high-thermal conductivity and high-elasticity acrylate rubber consists of 100 parts by weight of comb type acrylate rubber, 20-40 parts by weight of elastomer, 3-6 parts by weight of a compatilizer, 2-8 parts by weight of a plasticizer, 15-35 parts by weight of a toughening agent, 3-5 parts by weight of a coupling agent, 1-3 parts by weight of a vulcanizing agent, 0-5 parts by weight of pigment and 36-80 parts by weight of composite filler. The high-thermal conductivity and high-elasticity acrylate rubber provided by the invention is novel in effect mechanism and excellent in product comprehensive performance and can meet the existing actual use needs.

Description

[0001] This application is a divisional application of a patent with the application number 201610580449.9, the application date is July 22, 2016, and the invention name is "A High Thermal Conductivity and High Elasticity Acrylic Rubber". technical field [0002] The invention relates to an acrylic rubber, in particular to an acrylic rubber with high thermal conductivity and high elasticity. Background technique [0003] Acrylate rubber refers to an elastomer obtained by copolymerization of acrylate as the main monomer. Its main chain is a saturated carbon chain and its side groups are polar ester groups. It has excellent heat resistance, aging resistance, oil resistance, and Ozone, anti-ultraviolet and other properties, mechanical properties and processing properties are superior to fluororubber and silicone rubber, and its heat resistance, aging resistance and oil resistance are superior to nitrile rubber, and it is widely used in various high temperature and oil resistant ...
