Problems solved by technology

Fluorosilicone rubber is a new type of special rubber, which combines the advantages of fluororubber and silicone rubber. Compared with fluororubber or silicone rubber, fluorosilicone rubber is more difficult to synthesize, so the cost is higher, which limits its electrical conductivity. Application in rubber

Abstract

The invention discloses a high tensile strength rubber composition. The high tensile strength rubber composition is prepared from, by weight, 50-100 parts of silicon rubber, 20-60 parts of fluororubber, 5-10 parts of nanometer zinc oxide, 30-60 parts of conductive filler, 1-5 parts of a sulfurizing agent, 1-5 parts of rosin, 5-10 parts of sulphur, 10-20 parts of calcium carbonate, 1-5 parts of diethyldithiocarbamate zinc thiocarbamate, 3-15 parts of a silane coupling agent, 10-20 parts of an anti-aging agent and 10-20 parts of a reinforcing agent. The silicon rubber, the fluororubber, the conductive filler, the anti-aging agent, the reinforcing agent, the sulfurizing agent and the silane coupling agent are made into the conductive rubber composition with the good characteristics of the silicon rubber and the fluororubber, and the high tensile strength rubber composition has the advantages that the silicon rubber is small in volume resistivity, small in hardness, resistant to high and low temperature and aging, good in processing and manufacturing technological performance and capable of achieving the oil resistance and solvent resistance of the fluororubber, the volume change rate is only 1.2%, the volume change rate of traditional silicon rubber through the same test is 25%, and the volume change rate of the fluororubber is 3%, and the sample obtained through the technical scheme remarkably improves oil resistance and solvent resistance.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a rubber composition with high tensile strength and a preparation method thereof. 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. Conductive rubber is based on rubber, filled with mixed conductive fillers and cross-linking agents. It has good conductivity and filling performance, and is widely used in the fields of electronics, telecommunications, electric power, military industry, aviation, aerospace and ships, etc., and is mostly used for sealing and sealing of electronic and microwave waveguide systems such as chassis, cabinets, and shelters. Electromagnetic shielding occasions. Most of the existing conductive rubbers are based on silicone rubber. Compared with general conductive rubber, conductive silicone rubber has the ...
