Abstract

The invention relates to an organic copper composite rubber composite material and a preparation method thereof. The organic copper composite rubber composite material comprises rubber, a filler, brass powder, ZnO, stearic acid, a plasticizer, an anti-aging agent, sulfur and an accelerant. The material disclosed by the invention can be obtained by an internal mixing or open mixing method. Brass isused as a novel filler to be applied to the composite material, copper can be crosslinked with rubber through sulfur to form a Cu-S-rubber structure, interfacial stress is eliminated, and the purposeof enhancing the rubber is achieved. Meanwhile, the copper-zinc alloy endows the material with higher microhardness, can provide a higher friction coefficient, enhances the rubber-interface interaction, is beneficial to enhancing the rubber-interface contact friction coefficient, and improves the dry and wet gripping friction properties of tires, conveyor belts and other rubber products.

Description

technical field [0001] The invention relates to an organic copper composite rubber composite material and a preparation method thereof, belonging to the technical field of composite materials. Background technique [0002] A high coefficient of friction can endow the rubber composite material with a higher bonding force with the interface, which is suitable for rubber products such as conveyor belts and tires. Taking tires as an example, the microhardness of silica is usually used to improve the dry and wet friction coefficients. However, amorphous precipitated silica is mostly used in tires, and the particle modulus is relatively low, so the improvement effect on the friction coefficient is limited. Contents of the invention [0003] One of the purposes of the present invention is to overcome the deficiencies in the prior art and provide an organocopper composite rubber composite material that is beneficial to improving the anti-destructive performance and the friction co...
