摘　　要：以过硫酸铵/硫代硫酸钠为氧化还原引发体系,在低温下研究制备出了短切毡用的醋酸乙烯酯与丙烯酸酯类共聚物粘结剂。结果表明:采用氧化还原引发体系可以使聚合反应低温快速进行;并从配方和工艺两方面调节制备出渗透快、内增塑、柔软性优良的玻璃纤维短切毡粘结剂。With ammonium persulfate/sodium thiosulfate as Redox initiator system, a binder based on vinyl acetate/acrylate copolymer used for chopped strand mat was prepared at low temperature. The test results showed that the Redox initiator system could speed up the polymerization at low temperature. In addition, both the binder formulation and synthesizing technology were improved to make the binder fast wet-out, internally plasticized and able to produce flexible mats.
