  • METHOD FOR PREPARING BUTYRONITRILE RUBBER POWDER-BASED PVC THERMOPLASTIC ELASTOMER AND USE OF BUTYRONITRILE RUBBER POWDER-BASED PVC THERMOPLASTIC ELASTOMER IN PREPARING AUTOMOTIVE PARTS
    Publication number: 20230074196
    Abstract: A method for preparing a butyronitrile rubber powder-based polyvinyl chloride (PVC) thermoplastic elastomer and a use of the butyronitrile rubber powder-based PVC thermoplastic elastomer in preparing automotive parts are provided. The method includes: activating a wasted nitrile butadiene rubber (NBR) powder; plasticizing one of NBR and chloroprene rubber (CR) to obtain a plasticized rubber; dispersing the activated NBR fine rubber powder with one of PVC and chlorinated polyethylene (CPE) in a kneader evenly to obtain a mixture; adding the mixture and pine tar into the plasticized rubber, then mixing evenly to obtain a mixed plastic; adding various compounding agents into the mixed plastic and dispersing evenly to perform cross-linking reaction, thereby obtaining the butyronitrile rubber powder-based PVC thermoplastic elastomer.
