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 MMA, VAc and BA as comonomers, ethylene glycol dimethacrylate (EGDMA) and divinylbenzene (DVB) , Sodium dodecyl sulfate (SDS) and octylphenol polyoxyethylene ether (OP-10) as the composite emulsifier and potassium persulfate (KPS) as the initiator, Emulsion adhesive. Through the single factor test method, the best process conditions for preparing the vinegar-acrylic emulsion adhesive were optimized. The results showed that when m (OP-10): m (SDS) = 3:1 and w (composite emulsifier) = 3% (VAc) = 20:10, m (BA): m (VAc) = 50:20 and w (KPS) = 0.5%, the overall performance of the vinegar-based acrylic emulsion adhesive is relatively good and fully meets the requirements of the table tennis racket .
