Problems solved by technology

It has excellent oil resistance and solvent resistance, but its strength is not high, its aging resistance and processability are not good, and it has odor. It is often used together with nitrile rubber
[0006] At present, there are cattle fence rubber products on the market, but most of the rubber sheet formulations do not meet the environmental protection requirements, and the rubber sheets are not good enough in flex crack resistance, aging crack resistance and heat aging resistance, and the heat generation is slightly higher

Abstract

The invention provides cow mat rubber and a preparation method thereof. The rubber is prepared by four sections of rubber refining: the first section, adding natural rubber, aramid short staple, graphene master batch, environment-friendly oil, environment-friendly low-zinc rubber master batch, stearic acid, an anti-ageing agent, paraffin, cabot V9HX1 carbon black; the second section, adding cabotV9HX1 carbon black; the third section, plastifying again, finally refining and adding an accelerant M, an accelerant DM and sulfur. The invention further discloses the preparation method of the cow mat rubber. An existing rubber plate formula has no environmental friendliness; furthermore, warping fracturing resistance, ageing fracturing resistance and thermal ageing resistance of the rubber plateare not excellent enough, and heat generation is a little high. A cow mat prepared by the rubber disclosed by the invention can meet the green and environment-friendly requirements. The service lifeof the rubber prepared by the existing rubber formula is about 13 months, and fracturing and ageing phenomena may happen; the service life of the rubber prepared by the formula disclosed by the invention is 21 months, and the service life is prolonged by 60%.

Description

[0001] Technical field: [0002] The invention relates to the field of rubber materials, in particular to a cowpen mat rubber and a preparation method thereof. [0003] Background technique: [0004] Rubber is a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under a small external force. After removing the external force, it can return to its original shape. Early rubber was taken from plants such as rubber trees and rubber grasses. latex, which is processed into a material that is elastic, insulating, impermeable to water and air. Rubber is divided into two types: natural rubber and synthetic rubber. Natural rubber is processed by extracting gum from rubber trees, rubber grass and other plants; synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in industry. or aspects of life. [0005] Special type rubber refers to rubber with certain special pro...
