Abstract

The invention discloses a rubber material applied in a high-temperature working environment and a preparation method thereof. The rubber material is prepared from, by weight, 1-2 parts of arabic gum, 1-3 parts of zinc dialkyl dithiophosphate, 1-2 parts of an accelerant DM, 2-4 parts of epoxy tall oil acid butyl ester, 1-2 parts of hexamethyl cyclotrisiloxane, 20-30 parts of polyacrylonitrile, 10-15 parts of graphite, 2-3 parts of a softening agent, 3-4 parts of fly ash microspheres, 40-55 parts of liquid nitrile rubber, 50-60 parts of nitrile rubber, 20-25 parts of butadiene styrene rubber, 22-25 parts of coking coal powder, 3-5 parts of urea, 8-10 parts of a filling agent, 2-5 parts of aluminum hydroxide, 12-15 parts of boron nitride and 2-3 parts of thiuram. The rubber material has the good high temperature resistance, acid resistance, oil resistance and flame retardance and can be well applied to a high-temperature area.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a rubber material whose working environment is high temperature. Background technique [0002] Rubber material is a polymer material that can quickly recover from deformation under large deformation. It is one of the important basic industries of the national economy. It provides light industrial rubber products for daily use and medical use that are indispensable in people's daily life; for mining , transportation, automobile, construction, machinery, electronics and other heavy industries and emerging industries provide a variety of rubber production equipment or rubber parts, which are widely used. In recent years, the rapid development of the rubber industry has put forward higher requirements for rubber products, and rubber materials must develop in the direction of functionalization, refinement and diversification. The traditional single rubber material can no lon...
