High-performance magnetic rubber and preparation method thereof

Abstract

The invention discloses high-performance magnetic rubber and a preparation method of the high-performance magnetic rubber. The high-performance magnetic rubber is prepared from the following raw materials in percentage by weight: 41.225 percent of natural rubber, 5.154 percent of SrO.6Fe2O3, 1.296 percent of peroxide vulcanizing agent, 2.945 percent of ZnO, 0.353 percent of stearic acid, 0.294 percent of accelerator, 0.353 percent of anti-aging agent, 47.114 percent of carbon black, 0.353 percent of plasticizer, 0.471 percent of paraffin and 0.442 percent of fatty acid. The invention also discloses the preparation method of the high-performance magnetic rubber. The high-performance magnetic rubber disclosed by the invention has the advantages of high strength, high temperature resistance, oil resistance, cold resistance, tensile resistance, aging resistance and good vibration damping performance, the damping characteristic of the natural rubber is enlarged, the manufacturing cost is saved, and the requirements of vibration damping products in the high-performance and high-technology field such as automobiles, engineering machinery, hydraulic transmission, aviation and navigation can be met.

Description

technical field [0001] The invention relates to a high-performance magnetic rubber and a preparation method thereof, belonging to the technical field of rubber. Background technique [0002] At present, most of the vibration damping systems and components of automobiles are rubber products, among which natural rubber has high elasticity, high elongation strength, excellent tear resistance and electrical insulation, good wear resistance and cold resistance, and good processability. Good, easy to bond with other materials, etc., in terms of comprehensive physical and mechanical properties, it is superior to most synthetic rubbers, so most of the vibration damping systems use natural rubber. However, single-component natural rubber also has defects in terms of wear resistance and aging resistance, ozone resistance, and low temperature brittleness, and as the car works and the intrusion of road sand and dust, the rubber body itself will cause permanent damage. Due to permanent ...

AI Technical Summary

Problems solved by technology

At present, in the research of magnetic materials, most researchers aim to improve the damping characteristics and temperature threshold. Basically, various magnetic powders are mixed into the rubber body. Although the mechanical properties of various rubbers have been greatly improved, but The cost is too high and the drug formula is complicated, so it cannot be widely used in engineering
