Abstract

The invention discloses corrosion-resistant rubber and a preparation method thereof. The preparation method comprises the following steps: mixing natural rubber, nitrile rubber, fluorosilicone rubber,potassium pyrrolidone carboxylate, mica powder, aluminum hydroxide, zinc oxide, glycerol, triethanolamine, paraffin, magnesium stearate, an anti-aging agent MB, polyurethane, a vulcanization accelerator and a reinforcing filler, and carrying out ball-milling treatment to obtain a mixture M; plasticating the mixture M to obtain plasticated rubber N; and mixing the plasticated rubber N, and vulcanizing the plasticated rubber N to obtain a rubber blank.

Description

technical field [0001] The invention relates to the field of rubber, in particular to a rubber body and a preparation method thereof. Background technique [0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under a small external force, and can return to its original shape after the external force is removed. Early rubber was latex from plants such as rubber trees and rubber grasses, which were processed into materials that were elastic, insulating, impermeable to water and air. It is a high elastic polymer compound. Rubber is divided into two kinds of natural rubber and synthetic rubber. Natural rubber is processed by extracting colloids from rubber trees, rubber grass and other plants; synthetic rubber is obtained by polymerization of various monomers, and rubber products are widely used in various aspects of industry and life. In the field of chemical manufacturing, ru...
