High-acrylonitrile NBR/PVC (nitrile-butadiene rubber/polyvinyl chloride) oil-resistant ozone-resistant rubber material and preparation method thereof
2013
The invention relates to a rubber material and a preparation method thereof, particularly a high-acrylonitrile NBR/PVC (nitrile-butadiene rubber/polyvinyl chloride) oil-resistant ozone-resistant rubber material and a preparation method thereof. The material comprises the following components in parts by mass: 70 parts of NBR, 30 parts of PVC, 5 parts of ZnO, 1.5 parts of stearic acid, 40-50 parts of plasticizer, 50-80 parts of filler reinforcer, 0.5-2 parts of vulcanizing agent, 1.5-3.5 parts of accelerator, 3.0 parts of anti-aging agent, 2 parts of stabilizer and 2 parts of paraffin. The universal synthetic resin PVC has excellent ozone aging resistance and chemical corrosion resistance; the composite material blended from the NBR and PVC integrates the property advantages of the NBR and PVC, and overcomes the defects of the NBR and PVC, thereby becoming an important new rubber/plastic composite material. The high-acrylonitrile-content NBR and the PVC are blended, so that the blended rubber has favorable oil resistance and ozone resistance.
