摘　　要：以丙烯酸乙酯(EA)和丙烯酸丁酯(BA)为软单体,甲基丙烯酸甲酯(MMA)、苯乙烯(St)和丙烯腈为硬单体,甲基丙烯酸羟乙酯(HEMA)和甲基丙烯酸(MAA)为交联单体,十二烷基硫酸钠(SDS)和过硫酸铵(APS)分别为乳化剂和引发剂,通过半连续化种子乳液聚合的方法制备得到丙烯酸酯基础乳液,然后加入适量固化剂和硫化剂制备得到一种FPC用改性丙烯酸酯胶黏剂。通过单一变量法和正交实验得到丙烯酸酯基础乳液的最优配方为:m(软单)∶m(硬单体)∶m(交联单体)m(乳化剂)∶m(引发剂)=65∶30∶4∶3∶0.3。此时包封样的剥离强度为0.92 N/mm,单面板对压样的剥离强度为2.15 N/mm,耐焊性通过率为100%,胶膜吸湿率为3.11%,均能够满足FPC基材中胶黏剂的性能要求。Using ethyl acrylate(EA)and butyl acrylate(BA)as soft monomers,methyl methacrylate(MMA),styrene(St),and acrylonitrile as hard monomers,methyl Hydroxyethyl acrylate(HEMA)and methacrylic acid(MAA)as crosslinking monomers,sodium dodecyl sulfate(SDS)as emulsifiers,and ammonium persulfate(APS)as initiators,an acrylate base emulsion was prepared through semi-continuous seed emulsion polymerization.And then a modified acrylate adhesive for FPC was prepared by adding suitable amount of curing agent and vulcanizing agent to emulsion.The optimal formulation of the acrylate base emulsion was obtained by simple variable method and orthogonal experiment,that is as follow:m(soft monomer):m(hard monomer):m(crosslinking agent):m(emulsifiers):m(initiators)=65:30:4:3:0.3,w(SDS)=2%,w(APS)=0.3%.With this formulation,the peel strength of the encapsulation sample is 0.92 N/mm,the peel strength of the single panel is 2.15 N/mm,and the soldering resistance pass rate is 100%,the moisture absorption rate of the film is 3.11%,which can all meet the performance requirements of adhesivein the FPC substrate.
