| 摘 要： | 以氯硅烷为原料合成了一种新型的甲基苯基硅树脂,并制备了复合材料。通过热重分析、扫描电镜研究了复合材料的热性能和填料分布,分析了影响复合材料弯曲强度的可能因素。实验结果表明,复合材料的热稳定性优良,在N2气氛下升温至800℃时,热失重仅为4.4%;复合材料截面为连续相,填料在硅树脂中分散均匀,两者相容性较好;填料的添加量、硅树脂的苯基含量及凝胶化时间是材料弯曲强度的三个主要影响因素。

| Abstract: | Composites were prepared by fillers and silicone resin which was synthesized by the chlorosilane.Thermal properties and section′s micrograph of the composites were studied by thermogravimetric analysis(TGA) and scanning electron microscope(SEM).The results of the experiments show the thermal property of the composites is excellent,its mass loss is only 4.4% when being heated to 800 ℃ in N2.The cross section of the composite is the continuous phase and the filler was uniformly distributed in the silicone resin.The filler and silicone resin’s compatibility is good.The content of quartz powder,gel time and phenyl′s content of the silicone resin are three main factors of the composites′ bending strength. |
