Abstract

The invention discloses a gas tank rubber sealing membrane sizing material composition and a preparation method thereof, and relates to the technical fields of a rubber sizing material composition andpreparation thereof. According to the composition, hydrogenated butadiene-acrylonitrile rubber is plasticated, so that a regulated degree of plasticity is achieved, plastification swelling treatmentis performed on PVC, and the PVC subjected to plastification swelling treatment and the plasticated hydrogenated butadiene-acrylonitrile rubber are blended; then additives, such as a reinforcing agent, a sulfurizing agent and a softening agent, are added into a blended material of the hydrogenated butadiene-acrylonitrile rubber and the PVC by weight percent, and then conventional mixing is performed, so that the composition is obtained. The composition has excellent gas tightness, weather resistance and cold tolerance.

Description

technical field [0001] The invention relates to the technical field of a rubber compound composition and a preparation method thereof, in particular to a gas cabinet rubber sealing film compound composition and a preparation method thereof. Background technique [0002] At present, the rubber sealing membrane of gas cabinets produced in China is mainly made of nitrile rubber, which is processed through dozens of processes such as masticating, banburying, blending with PVC, calendering and vulcanization. Whether the rubber sealing film of the gas cabinet can have excellent air tightness, ozone resistance, hydrogen sulfide gas corrosion resistance, weather resistance, and aromatic hydrocarbon solvent resistance mainly depends on the rubber type and the formula of the rubber material. In addition to oil resistance, rubber parts also need to have good heat resistance, high temperature resistance, high pressure, oxygen resistance and other characteristics, while ordinary nitrile ...
