The adhesive material for the transition layer comprises the following components in parts by weight: 60-70 parts of carboxyl nitrile rubber, 30-40 parts of natural rubber, 20-40 parts of general carbon black, 10-20 parts of white carbon black, 45-50 parts of silane coupling agent, 4-6 parts of tackifying resin, 5-8 parts of zinc oxide, 1-2 parts of stearic acid, 3-3.5 parts of accelerator and 1-1.5 parts of valcanizer.

Description

technical field [0001] The invention relates to a composite rubber product, in particular to a rubber material for laminating a composite bonding transition layer of hydrogenated nitrile rubber and unsaturated non-polar rubber. Background technique [0002] Unsaturated non-polar rubber, such as natural rubber (NR), styrene-butadiene rubber (SBR), butadiene rubber (BR), etc., has good elasticity, high strength, low heat generation, good flex resistance, and low hysteresis loss, but Poor heat resistance, poor oil resistance, poor solvent resistance, poor aging resistance, these shortcomings greatly limit the scope of use of unsaturated non-polar rubber. [0003] Hydrogenated nitrile rubber (HNBR) not only maintains the oil resistance of unsaturated non-polar rubber, has excellent wear resistance, but also has excellent heat resistance, weather resistance, oxygen resistance, chemical corrosion resistance and high tensile strength properties , especially the heat resistance has...
