以杂氮硅三环衍生物为增粘剂，制备了加成型粘接有机硅灌封胶。研究了导热填料用量、导热填料处理方式、增粘剂用量以及A值(硅氢基与硅乙烯基摩尔比)对加成型有机硅灌封胶粘接性能影响。结果表明，当导热填料硅微粉用量150份、导热填料硅微粉采用A171表面处理、增粘剂用量2．0份、A值1．4时，制备出对铝材、PA、ABS、PC粘接性能良好且导热、阻燃等综合性能优异的加成型有机硅灌封胶。
An addition curable silicone encapsulant with the adhesion properties has been prepared with carbasi-latrane derivative as tackifier. Effects of amounts of fillers,different modification methods,amounts of the tackifier and A value on the adhesion properties of silicone encapsulants were investigated. The results showed that,when the loading quartz powder was 150 phr,modified by A171,the loading tackifier was 2 phr and A value was 1. 4,the addition curable silicone encapsulants was prepared with excellent adhesion for aluminum, PA, ABS and PC, and with excellent comprehensive properties such as thermal conductivity,flame retardance.
