摘　　要：采用SBS热塑性弹性体为胶粘剂主要原料,松香为增粘剂,环己烷为溶剂,OP-10 为乳化剂,制备出一种新型以O/W型乳状液形态存在的环境友好型纸塑复合胶粘剂。考察了乳化时间、乳化速率、表面活性剂用量、SBS 浓度以及含水量等参数对SBS乳状液稳定性的影响,并获得了优化工艺参数条件。制备的水乳胶粘接强度足够大,满足纸塑复膜的应用要求,还初步考察了聚合物PVA对此种SBS乳状液稳定性的影响,并借助显微镜直接观察了PVA的加入所引起水乳胶粒度的变化。A new kind of oil in water emulsified SBS paper-plastic laminating adhesive was prepared with SBS thermoplas- tic elastomer as the main material, rosin as the viscosity increaser, cyclohexane as the solvent and OP-10 as the emulsifier. The SBS laminating adhesive is an enviroment-friendly adhesive existing in the form of O/W emulsion, whose stability directly affects its performance. The effects of emulsifying time, stirring rate, dose of emulsifier, concentration of SBS and water content on the stability of SBS emulsion were studied. And the optimal parameters for emulification were obtained. A simple application was made with this adhesive, which showed that its adhesive strength was enough for adhesion of paper and plastic film. The effect of PVA on the emulsion was studied, and results said that the increase of the emulsion on stability was in evidence by adding PVA, whilst the microscope was used to directly observe the varying of drop size of emulsion with PVA concentration.
