以金刚石粉、环氧树脂E-20、甲醚化氨基树脂、助剂制备成双组分导热绝缘胶粘剂,在130℃保温30min,210℃保温10min固化。胶粘剂固化后导热系数随金刚石粉含量增加先增大后减少,存在一个极大值。相同金刚石粉含量下,较大粒径的金刚石粉之间能形成更好的物理接触,有利于导热性能的提高。 A two-component thermal conductive insulating adhesive was prepared by using diamond powder, epoxy resin E-20, methyl-etherified amino resin and auxiliary agent, and was cured at 130 ° C. for 30 minutes and 210 ° C. for 10 minutes. After curing the adhesive thermal conductivity increases with the diamond powder content increases first and then decreases, there is a maximum value. The same diamond powder content, the larger size of the diamond powder to form a better physical contact between, conducive to the improvement of thermal conductivity.
