摘要
根据分子设计原理,对苯丙(苯乙烯-丙烯酸酯)乳液配方工艺进行优化,重点考察了引发剂、乳化剂及功能性单体的用量对苯丙胶乳的粒子形貌、储存稳定性、粘度及粘结强度等性质的影响.结果表明,m(苯乙烯)∶m(丙烯酸丁酯)≈1∶1,引发剂和功能性单体的质量分数分别为单体总量的0.3%和2%,阴离子、非离子乳化剂复配使用,并采用引发剂滴加工艺,制备的胶乳具有较好的纸塑粘结性能.
The influences of the concentration of initiator, emulsifier and functional monomer on the properties of latex such as the stability of preservation, viscosity, particle diameter and the adhesive strength were investigated in this paper. The result demonstrates that the optimum technologic conditions are： mass ratio of styrene and butyl-acrylate is about 1 ： 1, the amount of initiator and functional monomer are 0. 3 wt % and 2 wt % of that of polymeric monomer respectively, with anionic and nonionic complex emulsifier and adding the initiator in dropwise. The obtained latex shows good comprehen- sive properties for paper-plastic adhesive.
