制备参数对纳米SiO2/有机硅/环氧树脂复合材料性能的影响

The effect of preparation process parameters on capability of Nano-SiO2/Epoxy resins/Organosilicon

    摘要
  • 摘要: 利用偶联剂处理后的纳米SiO2粒子改性环氧树脂制备纳米SiO2/环氧树脂/有机硅复合材料.IR分析表明:纳米SiO2与环氧树脂/有机硅形成了复合体.运用均匀设计考察了各种实验参数对复合材料的热分解温度,体积电阻率的影响.建立了复合材料热分解温度、体积电阻率在制备过程中的数学模型.模型方差分析表明所有模型都是充足的.实验结果表明纳米SiO2对环氧树脂有明显的改性作用.随着纳米SiO2的加入量的增加,复合材料的热分解温度提高而电阻率降低.

     

    Abstract: Nano-SiO2/epoxy resins/Organosilicon was prepared by modification epoxy resins/Organosilicon with nano-SiO2 treated by coupling agent.Composites of nano-SiO2/epoxy resins/Organosilicon were indicated by IR analysis.It was shown by TGA and volume resistances analyses that epoxy resins were modified obviously by nano-SiO2.A model for heat compounded temperature and volume resistivity of Nano-SiO2/epoxy resins/Organosilicon composite in the preparation process was developed by uniform design.Analysis of variance revealed that the models developed were adequate.The heat compound temperature can be increased with the increase of Nano-SiO2 but the volume resistances can be decrease as the increased of Nano-SiO2.
