| 摘 要： | 采用预乳化半连续聚合法合成了保护膜用乳液型压敏胶(PSA),探讨了单体、乳化剂、引发剂、缓冲剂和交联剂等对乳液型PSA剥离强度增幅的影响。结果表明:乳液型PSA剥离强度增幅随丙烯酸丁酯(BA)或复合乳化剂用量的增加呈先降后升的态势,随丙烯酸(AA)或缓冲剂用量的增加而增大,随苯乙烯(St)、丙烯酸-2-羟丙酯(HPA)或引发剂用量的增加而减小;当w(BA)=85%时,剥离强度增幅最小;大分子有机硅和交联剂的加入能明显降低PSA剥离强度增幅,当w(大分子有机硅)=1.0%时,剥离强度增幅最小;当加入相同用量的交联剂GA240或SC-100时,前者使PSA的剥离强度增幅更低。

| Abstract: | The emulsion type pressure sensitive adhesive(PSA) for protective film was prepared by pre-emulsified semi-continuous polymerization,the influences of some factors(such as monomer,emulsifier,initiator,buffering agent,cross linker and other factors) were discussed on increasing range of emulsion type PSA peeling strength.The results showed that the increasing range of emulsion type PSA peeling strength had trend of fall-rise with increasing butyl acrylate(BA) or composite emulsifier contents,and had trend of... |
