Problems solved by technology

The performance of nitrile rubber is affected by the content of acrylonitrile. As the content of acrylonitrile increases, the tensile strength, heat resistance, oil resistance, water resistance, air tightness and hardness increase, but the elasticity and cold resistance decrease.
Existing nitrile rubber is widely used due to its oil resistance, but its elasticity is low and it is difficult to meet certain use environments. Now there is a need for a rubber material with excellent elastic properties, good impact resistance, and less rubber Toxic and harmful substances in materials, reducing the harm to the environment

Abstract

The invention discloses an environment-friendly high-elasticity rubber material which is prepared from the following raw materials in parts by weight: 30-40 parts of powder nitrile-butadiene rubber, 10-18 parts of polyvinyl chloride thermoplastic elastomer, 10-20 parts of ABS (acrylonitrile-butadiene-styrene) resin, 3-5 parts of p-tert-butyl phenol-formaldehyde resin, 1.5-2 parts of sulfur, 1.2-1.8 parts of accelerator TMTD (tetramethyl thiuram disulfide), 2-4 parts of magnesium oxide, 1-3 parts of zinc oxide, 5-8 parts of epoxy soybean oil, 0.5-1 part of paraffin, 1-3 parts of zinc-barium stabilizer, 2-3 parts of organophosphate, 20-30 parts of modified kaolin, 15-20 parts of silica white, 1.5-3 parts of carbon master batch and 0.5-1.5 parts of novel rubber reinforcing agent XRE. The rubber material has the advantages of excellent elasticity, wear resistance, favorable tear resistance and low cost, and reduces the hazard to the environment.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to an environment-friendly high-elastic rubber material. Background technique [0002] Nitrile rubber has excellent oil resistance, second only to polysulfide rubber and fluorine rubber, and has excellent wear resistance and air tightness. The heat resistance is better than that of styrene-butadiene rubber and neoprene, and it can work at 120°C for a long time. Air tightness is second only to butyl rubber. The performance of nitrile rubber is affected by the content of acrylonitrile. As the content of acrylonitrile increases, the tensile strength, heat resistance, oil resistance, water resistance, air tightness and hardness increase, but the elasticity and cold resistance decrease. Existing nitrile rubber is widely used due to its oil resistance, but its elasticity is low and it is difficult to meet certain use environments. Now there is a need for a rubber material with ...
