Problems solved by technology

[0004] Nanofillers are ideal reinforcements to achieve a combination of strength and toughness, but in practice their effect is much lower than theoretically predicted, mainly due to interface problems between the filler and the matrix

Abstract

The invention discloses interface modified chlorinated polyethylene rubber based on a novel reinforcing agent and a preparation method thereof. The interface modified chlorinated polyethylene rubber comprises the following raw materials in parts by weight: 80 parts of chlorinated polyethylene, 10 parts of the reinforcing agent, 5 parts of a coupling agent, 25 parts of a flame retardant, 10 parts of a stabilizer, 2 parts of an auxiliary stabilizer, 1.5 parts of a lubricant, 6 parts of a halogen-free plasticizer, 3 parts of a vulcanizing agent and 2 parts of a vulcanizing aid. The reinforcing agent is a nano-filler, the nano-filler is a boron carbide nanowire, and the boron carbide nanowire is obtained by heating a mixture of a carbon nanotube and boron powder by taking the carbon nanotube as a template; wherein the coupling agent is graphene, and the graphene is a high-quality graphene sheet and is directly prepared from graphite; and the stabilizer is a combination of magnesium oxide,stabilizer zinc glyceroxide and stabilizer magnesium stearate. The base material, the coupling agent, the reinforcing agent and the stabilizer are safe and environment-friendly, do not contain substances which cause great damage to the environment, and follow the development trend of green chemistry.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to an interface-modified chlorinated polyethylene rubber based on a novel reinforcing agent and a preparation method thereof. Background technique [0002] Rubber reinforcing agent is a compounding agent that can improve the strength of rubber products. In the past, the reinforcing material of the rubber industry has always been based on carbon black, accounting for more than 60% of the total rubber filler. There are a series of negative effects in the preparation and application of reinforcing material carbon black. Carbon black is a by-product of the petroleum industry, which has high cost and serious pollution during use. Therefore, people have been looking for substitutes for carbon black. [0003] For this reason, many researchers have developed many new reinforcing fillers, most of which are inorganic reinforcing fillers, mainly silicate and calcium carbonate mineral powders....
