摘 要:以甲基丙烯酸甲酯(MMA)、醋酸乙烯(VAc)和丙烯酸丁酯(BA)为共聚单体,乙二醇二甲基丙烯酸酯(EGDMA)和二乙烯基苯(DVB)为复合交联剂,十二烷基硫酸钠(SDS)和辛基酚聚氧乙烯醚(OP-10)为复合乳化剂,过硫酸钾(KPS)为引发剂,采用种子乳液聚合法制备了乒乓球拍用醋丙乳液胶粘剂。通过单因素试验法优选出制备醋丙乳液胶粘剂的较佳工艺条件。结果表明:当m(OP-10)∶m(SDS)=3∶1且w(复合乳化剂)=3%、m(DVB)∶m(EGDMA)=1∶2、m(MMA)∶m(VAc)=20∶10、m(BA)∶m(VAc)=50∶20和w(KPS)=0.5%时,醋丙乳液胶粘剂的综合性能相对较好,并且完全满足乒乓球拍的使用要求。With methyl methacrylate (MMA), vinyl acetate (VAc) and butyl acrylate (BA) as comonomers, ethylene glycol dimethacrylate(EGDMA) and divinylhenzene(DVB) as composite cross linker,sodium dodecyl sulfate (SDS) and octylphenol polyoxyethylene ether (OP- 10) as composite emulsifier, potassium persulfate (KPS) as initiator,a VAc-acrylate emulsion adhesive for table tennis ba! was prepared by seed emulsion polymerization. The better process conditions of preparing the VAc:-acrylate emulsion adhesive were preferred by single factor experiment. The results showed that the VAc-acrylate emulsion adhesive had relatively better combination property and could all meet application requirements for table tennis bat when the mass ratio of m(OP-10):m(SDS) was 3:1 and the mass fraction of composite emulsifier was 3% ,the mass fraction of KPS was 0.5% ,the mass ratio of m(DVB):m(EGDMA) was l:2,the mass ratio of m(MMA):m(VAc) was 20:10 and the mass ratio of m(BA):m(VAc) was 50:20.
