So SBS is used as rubber adhesive, it has strong elasticity and bonding strength, low temperature resistance、good in solubility、 low in solution viscosity、 quick in solidification and so on. And it can be made into rubber adhesive in almost every types , such as the ordinary type、pressure-sensitive type、laminated type、 contact type and so on. This article primary discuss the necessary solvent’s selection principles of environmental-friendly type SBS rubber and the different impacts on different solvent’s proportional, it also has done some researches on the impacts that tie resin and reinforced resin have brought toward rubber adhesive ‘s performance. Which environmental performance mainly from the start solvent selected non-toxic, non-volatile solvents harmful gases Preparation environmentally-friendly adhesive SBS. And the study of solvent conditions, tackifying resin, reinforced resin 、SBS reinforced elastomer and the appropriate amount of filling and fill in the amount of colloid under the comprehensive performance. By comparing the method to choose the best performance of the various additives specific ratio. 关键词:环境友好型 SBS胶粘剂 增粘树脂 增强树脂 Key words: environmental-friendly type SBS rubber adhesive tie resin reinforced resin
