摘　　要：介绍了一种水性纸塑复膜胶的制备方法。以丙烯酸丁酯、苯乙烯、丙烯酸和交联型功能单体为主要原料，采用单体预乳化种子乳液聚合工艺进行合成。讨论了单体的选择及配比对乳液性能和纸塑复合的影响、乳化剂对乳液稳定性的影响、引发剂对单体转化率的影响。结果表明：软硬单体丙烯酸丁酯与苯乙烯最佳配比是1．6～2．3：1，乳化剂和引发剂最佳用量分别为总单体量的0．98％和0．60％。制得的乳液粒径细腻、固含量高、黏度适中且稳定性好。A preparation method of watersoluble paper/plastic laminating adhesive is introduced. The main raw materials are butyl acrylate, styrene, acrylic acid and crosslinking functional monomer. The polymerization process is monomer pre - emulsified and seed emulsion polymerization method. The effect of the selection and proportioning of monomers on the emulsion performance and paper/plastic lamination, the influence of emulsifier on the emulsion stability and the effect of the initiator on the monomer conversion have been discussed. The results showed that the best ratio of soft and hard monomer butyl acrylate to styrene is 1.6 - 2.3： 1. The optimal dosage of emulsifier and initiator is 0.98% and 0.60% of total monomer＇s mass respectively. The prepared emulsion has delicate particle size, high solid content, moderate viscosity and excellent stability.
