Abstract

The invention provides a method for preparing a mechanical rubber material, and the method comprises the following steps: a, mixing and kneading epoxy natural rubber, ethylene propylene rubber and styrene-butadiene rubber, adding modified clay emulsion, and stirring to obtain a mixture I; b, mixing modified rubber emulsion, modified asphalt emulsion, a coupling agent and an antifoaming agent, stirring and heating to obtain a mixture II; c, mixing diatomaceous earth, silica powder, an anionic surfactant and deionized water to beat, adjusting the pH, adding a composite material, and stirring toobtain a mixture III; and d, introducing the mixture I, the mixture II, and the mixture 3 III into a mixer, adding a crosslinking agent, stirring, mixing, and extruding by a twin-screw extruder. The method can significantly improve the tensile and aging resistance of prepared rubber.

Description

technical field [0001] The invention belongs to the technical field of rubber materials, and in particular relates to a method for preparing rubber materials for machinery. Background technique [0002] Natural rubber is made by coagulating and drying the latex that flows out from Hevea clover tree tapping. The finished product after processing is a material that is elastic, insulating, impermeable to water and air. It is mainly divided into two types of natural rubber and synthetic rubber. Natural rubber is processed after extracting gum from plants such as rubber trees and rubber grasses. Synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in all aspects of industry or life. It has a wide range of uses. Rubber can also be divided into natural rubber, general-purpose rubber, styrene-butadiene rubber, nitrile rubber, silicone rubber, butadiene rubber, isoprene rubber, ethylene-propylene rubber, and neoprene.
