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 ...
