Abstract

The invention discloses a synergetic composite rubber material and a preparation method thereof. The synergetic composite rubber material consists of the following components in percentage by mass: 30-60% of rubber powder, 10-20% of calcium carbonate, 5-15% of a plasticizer, 5-15% of a pressure withstanding agent, 5-15% of chlorosulfonated polyethylene, 5-15% of a styrene-butadiene segmented copolymer and 5-15% of a dispersant aluminum oxide. The preparation method of the synergetic composite rubber material comprises the following steps: 1, grinding raw materials of the components, and mixinga part of the components so as to obtain a mixture; 2, calcining the mixture at a high temperature and performing stirring so as to obtain a mixed liquid A; 3, adding other components, performing stirring, performing secondary heating so as to obtain a mixed liquid B, and performing press molding so as to obtain a rubber module; and 4, vulcanizing the rubber module, performing curing, and performing natural cooling, so as to obtain the synergetic composite rubber material. As the components are selected according to certain mass percentages and a series of processes are implemented, properties of pressure resistance and high-temperature resistance of rubber are effectively improved.

Description

technical field [0001] The invention belongs to the technical field of preparation of composite rubber materials, in particular relates to a synthetic composite rubber material, and also relates to a preparation method of the rubber material. Background technique [0002] Rubber is generally divided into natural rubber and synthetic rubber. Natural rubber is the latex directly extracted from rubber trees and rubber grass plants. After manual processing, it is made of materials with certain elasticity, insulation, impermeability, and air impermeability; Synthetic rubber is a high-elastic polymer compound, and synthetic rubber is obtained by processing various monomers after polymerization. Rubber products are widely used in all aspects of industry or life, and are indispensable items in people's daily life. The compression permanent deformation value of rubber is an important index to measure the sealing performance and shock absorption performance of rubber materials and th...
