Abstract

The invention discloses a high-performance electroconductive rubber which is prepared from the following components in parts by weight: 40-50 parts of neoprene, 50-60 parts of natural rubber, 20-30 parts of silvered glass powder, 10-15 parts of magnesium stearate, 1-5 parts of argil powder, 20-40 parts of graphitized carbon black, 5-8 parts of hydroxy silicone oil and 1-5 parts of paraffin. Compared with the prior art, the moldproof rubber disclosed by the invention is mainly prepared from the neoprene and natural rubber; since the natural rubber has the advantages of favorable tensile strength, favorable low-temperature softness and favorable electric insulativity, the product has the advantages of excellent electroconductivity, excellent shielding effect, excellent electric insulativity, favorable air permeability, favorable oxidation resistance and favorable high / low temperature resistance, and can be used in a severe environment; and the high-performance electroconductive rubber is easy for processing and molding.

Description

technical field [0001] The invention relates to a high-performance conductive rubber. Background technique [0002] At present, most of the conductive materials on the market use carbon black as the conductive medium, and the polymer base materials mainly use natural rubber, EPDM rubber, butyl rubber, etc., but they have disadvantages such as low conductivity and easy aging. Based on this, a conductive rubber made of silicone rubber as a carrier was invented by adding conductive fillers. It has excellent electrical and physical properties, excellent electrical conductivity, aging resistance, high and low temperature resistance, etc., and can be used in aviation , Aerospace, ships and other military electronic equipment, communication terminals, notebook computers, digital audio-visual and communication equipment, etc. Contents of the invention [0003] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a...
