摘要:
通过动态热机械分析仪(DMA)的静态热机械(TMA)分析法和示差扫描量热仪(DSC),测试得多种低收缩添加剂(LPA)的线性膨胀系数和玻璃化转变温度(Tg),加入不同LPA的团状模塑料(BMC)复合材料的线性收缩率,研究了BMC中LPA的抗收缩机理。结果表明:BMC复合材料的抗收缩效果不仅与LPA的线膨胀系数有关,还与LPA的玻璃化转变温度有关; 同时还通过扫描电镜(SEM)观察不同种类的LPA在BMC复合材料中的分散及形成的空穴的大小佐证了以上的联系。
Abstract:
The linear expansion coefficient, glass transition temperature of a variety of low shrinkage additive(LPA), and the linear shrinkage of bulk moulding compounds(BMC)with different LPA loading were tested by thermal mechanical(TMA)analysiser and differential scanning calorimetry(DSC). The anti-shrinkage mechanism of LPA in BMC was researched based on the above characterization. The results showed that the anti-shrink efficiency of BMC was not only related with the linear expansion coefficient,but also related with the glass transition temperature of LPA. The relationship was also corroborated by the dispersion of different LPA and the formation of cavities in BMC composites using scanning electron microscopy(SEM).
