Rubber material for motor cushion block

Abstract

The invention discloses a rubber material for a motor cushion block. The rubber material is prepared from, by weight, 40-80 parts of nitrile butadiene rubber, 15-30 parts of cis-rich butadiene rubber, 30-40 parts of isoprene rubber, 1-3 parts of zinc oxide, 0.5-1.5 parts of magnesium oxide, 1.5-2.5 parts of p-tert-butylphenol-formaldehyde resin, 0.5-1.2 parts of accelerant CZ, 0.5-1.5 parts of hexamethylenetetramine, 40-50 parts of carbon black, 20-40 parts of calcined clay, 15-35 parts of nano-vermiculite, 10-30 parts of modified nano-montmorillonite, 5-15 parts of glass fiber, 10-30 parts of heavy calcium carbonate, 5-12 parts of grain graphite, 1-3 parts of antiager 4010NA, 1-3 parts of antiager IPPD, 1-3 parts of antiager D and 1-3 parts of coal tar. The rubber material is good in hydrophobic performance and mechanical performance, resistant to high temperature and ageing and long in service life.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a rubber material for a cushion block of a motor. Background technique [0002] Due to the increasing shortage of international oil resources, the prices of various types of rubber continue to rise. In the next few years, the shortage of rubber resources will continue to plague countries, and the performance of rubber resources will become more and more important. The engine rubber pad is an important component for engine vibration reduction at the bottom of the automobile engine. Due to the working environment of the engine rubber pad, the performance requirements for the rubber material used are relatively high. Since the engine rubber pads vibrate frequently and violently in a high temperature environment, the engine rubber pads are frequently replaced, which greatly increases the cost of use. Therefore, how to prepare a hydrophobic, high temperature resistant, aging resistant,...
