摘要
为了提高环氧树脂的耐热性,采用笼型倍半硅氧烷(POSS)改性双酚A型环氧树脂E51,得到有机无机杂化树脂。采用Ozawa和Kissinger两种方法研究了杂化树脂/4,4′-二氨基苯砜(DDS)体系的固化反应动力学。TGA分析表明,POSS的加入提高了E51/DDS固化树脂体系的热性能。
In order to enhance the thermal resistance of epoxy resin,diglycidyl ether of bisphenol A （E51） was modified by polyhedral oligomeric silsesquioxane （POSS）to form organic-inorganic hybrid resin. The curing kinetics of the obtained POSS/E51/DDS hybrid resin system was studied by Ozawa and Kissinger methods,respectively. TGA analysis showed that the incorporation of POSS improved the thermal properties of the E51/DDS system remarkably.
