摘要
以醋酸乙烯酯(VAc)、丙烯酸丁酯(BA)、丙烯酸甲酯(MA)、丙烯酸(AA)和苯乙烯(St)为主要原料,采用预乳化兼种子乳液的聚合工艺制备醋-丙-苯乳液型纸塑干式复合胶粘剂,讨论了共聚反应的引发剂、聚合温度、聚合工艺及乳化剂的种类和用量对胶粘剂性能的影响。结果表明,采用0.5%氧化还原引发剂、反应温度70℃、预乳化兼种子乳液聚合工艺、2%的乳化剂用量,制得的乳液体系稳定、凝胶量少、剥离强度高、盖粉性强,能够完全满足目前纸塑复合生产线的要求。
In this paper, using vinyl acetate （ VAc）, butyl acrylate （ BA）, methyl acrylate （ MA ）, acrylic acid （AA）, and styrene （St） as the main components a vinyl acetate-acrylate-styrene emulsion adhesive for paper/plastic dry laminating was prepared by polymerization process of pre-emulsification and seed latex. The effects of initiator, reaction temperature, polymerization process, selection and content of emulsifier on the performance of the adhesive were discussed. The results indicated that when the amount of redox initiator is 0.5% by weight of monomers,the reaction temperature is 70 ℃ , using the polymerization process of pre-emulsification and seed latex emulsion and the amount of emulsifier is 2% by weight of monomers, the reaction system is stable, the residual monomer content and gel content in the obtained emulsion are lower, the emulsion adhesive has higher peeling strength and the adhesive completely meets the requirements of the product line for paper/plastic laminating.
