摘　　要：为了响应国家“双碳”战略,绿色制备了高强伸耐老化的乙丙胶粉基聚丙烯热塑性弹性体,优化了乙丙胶粉与聚丙烯的橡塑比,确定了相容剂的品种、用量,优化了乙丙胶粉与聚丙烯的化学接枝工艺。结果表明:环保相容剂2,4-二叔丁基过氧化异丙苯(BIBP)与硫磺S_(8)并用,乙丙胶粉基聚丙烯热塑性弹性体的力学和耐老化性能优异,拉伸强度达20MPa,扯断伸长率达800%以上,可用于耐老化汽车配件、码头缓冲器、各种胶管胶板等产品的负碳制备。In order to respond to the national“double carbon”strategy,this paper greenly prepared an ethylene propylene rubber powder-based polypropylene thermoplastic elastomer with high strength and aging resistance,optimized the ratio of ethylene propylene rubber powder and polypropylene,determined the variety and dosage of compatibilizers,and optimized the chemical grafting process between ethylene propylene rubber powder and polypropylene.The experimental results showed that using environmentally friendly compatible agent 2,4-di-tert-butylperoxyisopropylbenzene(BIBP)together with sulfur S_(8)could make the rubber powder-based polypropylene thermoplastic elastomer have excellent mechanical and aging resistance.The tensile strength reached 20MPa,and the elongation at break was more than 800%.This material could be used in the preparation of negative carbon for aging resistant auto parts,pier buffers,various rubber hoses and plates as well as other products.
