| 摘 要： | 为了改善传统贴片胶(SMA)的固化性能,以不同种类的环氧树脂(EP)作为基体树脂、不同潜伏性固化剂复配作为复合固化剂,制备了三种表面组装用SMA。采用差示扫描量热(DSC)法初步确定了固化剂的用量,并对三种SMA的玻璃化转变温度(Tg)和主要性能进行了对比试验。结果表明:以两种EP复配作为基体树脂,其SMA的综合性能优于单一EP基体树脂;当w(固化剂)=35%、w(触变剂)=6%时,该SMA可以在110℃、152 s条件下完全固化,其铺展值≤4.6%、塌落值≤5.4%、拉伸剪切强度为14 MPa且Tg值为89.7℃,说明该SMA既能快速固化,又具有较高的粘接强度和可修复性。

| Abstract: | In order to improve curing properties of traditional SMA(surface mount adhesives),so three different SMA for surface mount technology were prepared with different types of epoxy resins(EP) as matrix resin and different types of latent curing agents as composite curing agent.The curing agent content was initially determined by DSC method,and the contrast experiments for glass transition temperature(Tg) and main properties between three different SMA were implemented.The results showed that the combination pr... |
