Solvent-resistant corrosion-resistant rubber and preparation method thereof

Abstract

The invention discloses a solvent-resistant and corrosion-resistant rubber and a preparation method thereof. The solvent-resistant and corrosion-resistant rubber consists of the following parts by mass: 30-50 parts of natural rubber, 20-30 parts of nitrile rubber, and 20-30 parts of fluorosilicone rubber 30 parts, 3-7 parts of active zinc oxide, 3-9 parts of PE wax, 4-10 parts of n-butyl methacrylate, 3-8 parts of epoxy resin, 0.3-1.2 parts of anti-aging agent, 1-part of resorcinol 3 parts, polytetrafluoroethylene 6‑10 parts, coumarone resin 2‑5 parts, stearic acid 3‑6 parts, white carbon black 8‑15 parts, sulfur 10‑15 parts, accelerator AM‑2 3‑ 5 parts, 0.1-0.3 parts of anti-scorch agent CTP, the present invention is prepared by two-stage mixing method. The solvent-resistant and corrosion-resistant rubber of the invention has good resistance to organic solvents, strong acid and alkali resistance, corrosion resistance, excellent wear resistance and high temperature resistance, simple preparation, low cost and certain promotion value.

Description

technical field

[0001] The invention relates to the field of rubber industry, in particular to a solvent-resistant and corrosion-resistant rubber and a preparation method thereof. Background technique

[0002] In recent years, the rubber industry has developed a lot and has become one of the important basic industries of the national economy. It not only provides daily and medical light industrial rubber products that are indispensable for people’s daily life, but also provides various rubber production equipment or rubber parts for mining, transportation, construction, machinery, electronics and other heavy industries and emerging industries. It can be seen that the rubber industry has a wide variety of products, and the backward industry is very broad. However, many rubbers have single functional properties, such as good high temperature resistance, good oil resistance, or good wear resistance, but the comprehensive performance is not outstanding enough, resulting in a na...
