Abstract
The invention relates to a wearproof rubber material which is composed of a component A layer and a component B layer, wherein the component A layer is formed by organically bonding butadiene styrene rubber, butadiene rubber, carbon nanofibers and an organic silicon composition; the component B layer is formed by bonding chloroprene rubber, organic isoprene rubber, polybutadiene rubber, brominated butyl rubber and ethylene-propylene-diene monomer rubber, wherein the organic bonding mode is carried out via a high-temperature polymerization method, wherein the molar ratio of the butadiene styrene rubber to the butadiene rubber to the organic silicon composition is 2 to 1.5 to 3; and the molar ratio of the chloroprene rubber to the organic isoprene rubber to the polybutadiene rubber to the brominated butyl rubber to the ethylene-propylene-diene monomer rubber to natural rubber is 3 to 2.5 to 3.5 to 2.5. Based on a high-temperature polymerization mode, an insulated rubber layer and a wearproof rubber layer which are composed of multiple materials are polymerized at a high temperature so as to serve as a material of the insulated rubber layer, so that the wearproof rubber material has a relatively high insulating capacity and has the properties of wear resistance, aging resistance and high-temperature resistance.
Description
technical field [0001] The invention relates to a wear-resistant rubber material, which belongs to the field of rubber compositions and preparation methods. Background technique [0002] At present, the requirements for insulating materials in the market are getting higher and higher, because the current voltage is very huge. After the continuous impact of high voltage, the insulation performance of ordinary insulating materials is getting weaker and weaker. At the same time, because ordinary rubber The wear resistance and heat resistance of the material are average, and the rubber wires outside the wires are always exposed to the sun, so those rubber materials are often damaged, leakage occurs, and accidents are extremely prone to occur. For example, in vehicles such as cars and motorcycles, it is often necessary to use a rubber diaphragm, such as: rubber diaphragms for mechanical pumps, rubber diaphragms for automobile distributors, rubber diaphragms for automatic regulati...
