SBS胶粘剂溶剂的选择

Principle of solvent selection for SBS solvent adhesives

为了提高nano-SiO在树脂基体中的分散性,采用一2种超支化聚硅氧烷修饰的纳米二氧化硅(HBP-SiO)改性氰酸2酯(CE)树脂。利用非等温差示扫描量热法(DSC)研究了HBP-SiO/CE电子封装材料的固化动力学,求得其固化工艺参2数和固化动力学参数分别为:凝胶温度150.17℃,固化温度197.81℃,后处理温度258.97℃;表观活化能11.22kJ/mol,反-1应级数0.75,频率因子18342.84s。研究表明,HBP-SiO的加2入可以降低CE的活化能,使其固化反应可以在较低温度下进行。

A method used for solvent choice in SBS solvent based adhesives was discussesed in this paper.The solubility test,solvent-related parameters and Teas graph can be used to choose the solvent system,and it provide a convenience for development of a proper adhesion and low or no toxicity SBS solvent adhesive.
