塑/塑复合用水性复膜胶的研制

Study on water-based laminating adhesives for plastic/plastic lamination

在丙烯酸酯单体中加入一种特殊功能单体(HT),通过种子乳液聚合法制备了一种塑/塑复合用水性丙烯酸酯复膜胶(FM-45)。研究了丙烯酸酯复合功能单体配比对FM-45的剥离强度、乳化体系以及应用性能等影响。结果表明:当复合功能单体中m(丙烯酸)∶m(丙烯酸羟丙酯)∶m(HT)=2∶3∶1、w(复合乳化剂)=0.6%(相对于单体总量而言)时,FM-45的综合性能最佳。

With a special functional monomer（HT） as comonomer of acrylate monomers,so an water-based acrylate laminating adhesive（FM-45） for plastic/plastic lamination was prepared by seed-emulsion polymerization.The influences of composite functional monomers ratio for acrylates were investigated on the peeling strength,emulsification system and application properties of FM-45.The results showed that the combination property of FM-45 was best when mass ratio of re（acrylate acid）：m（hydroxylpropyl acrylate）：m（HT） was 2：3：1 ,mass fraction of composite emulsifier was 0.6% in total monomers.
