Abstract

The invention discloses an elastic rubber material applicable to work at a high temperature. The elastic rubber material is prepared from, by weight, 1.6-2 parts of Arabic gum, 1-2 parts of zinc dialkyl dithiophosphate, 1-1.4 parts of accelerant DM, 2-3 parts of epoxy tall butyl oleate, 1-1.4 parts of hexamethyl cyclotrisiloxane, 24-27 parts of polyacrylonitrile, 12-13 parts of graphite, 3-4 parts of coal ash microbeads, 0.7-1 part of lauryl sodium sulfate, 42-55 parts of liquid nitrile rubber, 0.6-1 part of methacrylic acid, 52-60 parts of chemigum, 20-25 parts of butadiene styrene rubber, 23-25 parts of coking coal powder, 4-5 parts of urea, 8-11 parts of carbon black, 14-17 parts of aluminium nitride and 2-3 parts of thiuram. The prepared rubber material is good in stability, high in thermal conductivity, capable of bearing the high temperature, free of deformation and damage, meanwhile good in strength, good in chemical corrosion resistance, good in impact elasticity, high in wear resistance and long in service life.

Description

technical field

[0001] The invention relates to the technical field of rubber, in particular to an elastic rubber material suitable for working under 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, 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 longer fully meet ...

Examples

Embodiment Construction

[0013] An elastic rubber material suitable for working at high temperature, prepared from the following raw materials in parts by weight (kg): gum arabic 1.6, zinc dialkyldithiophosphate 1, accelerator DM1, epoxy butyl oleate Ester 2, hexamethylcyclotrisiloxane 1, polyacrylonitrile 24, graphite 12, fly ash microbeads 3, sodium lauryl sulfate 0.7, liquid nitrile rubber 42, methacrylic acid 0.6, nitrile rubber 52. styrene-butadiene rubber 20, coke powder 23, urea 4, carbon black 8, aluminum nitride 14, thiuram 2.

[0014] The elastic rubber material suitable for working at high temperature is prepared by the following specific steps:

[0015] (1) Dilute the gum arabic with 7 times the amount of deionized water and stir evenly, mix and disperse coke powder, carbon black and aluminum nitride evenly, then add the mixed powder to the gum arabic solution, heat and stir until the water is Evaporated, dried and ground for later use;

[0016] (2) Add polyacrylonitrile to the dimethyl ...
