Conductive rubber composite material with excellent damping performance and preparation thereof

Abstract

The invention provides a conductive rubber composite material with good damping property and a preparation method thereof. The composite material has good conductivity and can reduce weight of rubber products. The composite material has polyaniline / perlite composite particles which are evenly distributed in a rubber matrix. The composite particles are perlite particles with polyaniline in pores and on surfaces, are 1-5mm and account for 25-50% of the composite material by volume. The rubber matrix can be styrene butadiene rubber matrix or butyl rubber matrix.

Description

1. Technical field

[0001] The invention relates to a rubber-based composite material containing an organic / inorganic porous medium and a preparation method thereof, in particular to a light-duty conductive rubber composite material with high damping, which belongs to the technical field of composite materials. 2. Background technology

[0002] Existing rubbers have good damping properties, but they cannot meet some special requirements, such as good electrical conductivity, so some high-damping rubbers have been proposed.

[0003] No. 01128908.2 patent application proposes a preparation method of wide temperature and broadband polyacrylate / polysiloxane composite damping rubber, which uses polysiloxane and polyacrylate blend vulcanization to widen the low temperature damping area of ​​polyacrylate, and then The blended rubber is the matrix interpenetrated with the poly(meth)acrylate sequence, which broadens the high temperature damping area of ​​the composite rubber, and obta...
