| 摘 要： | 以由单官能硅氧单元和四官能硅氧单元组成的有机硅树脂(简称MQ硅树脂)增强加成型硅橡胶为基体,采用机械共混方式加入少量纳米S iO2,研究了纳米S iO2对MQ硅树脂增强硅橡胶的性能影响。结果表明,纳米S iO2在硅橡胶中以聚集体的形式存在,大小约为几十到几百纳米;纳米S iO2填充MQ硅树脂增强的硅橡胶的邵尔A硬度、拉伸强度和扯断伸长率与未填充纳米S iO2的硅橡胶基本相当,撕裂强度增大;其高温热稳定性优于未填充纳米S iO2的硅橡胶,但其透明性稍有下降。

| Abstract: | The addition silicone rubber reinforced with MQ silicone resin which composed of mono-functional silicon-oxygen unit and tetra-functional silicon-oxygen unit and the modified rubber with nano-silicon dioxide based on above silicone rubber by machinery mixing way were prepared.The effect of nano-silicon dioxide on properties of silicone rubber were also studied.The experimental results showed that nano-silicon dioxide existed in the form of aggregate of the size from dozens to several hundred nanometers in the silicone rubber;and the Shore A hardness,tensile strength and elongation at break of the silicone rubber reinforced with MQ resin and modified with nano-silicon dioxide were compared with those of the silicone rubber without nano-silicon dioxide,while the tearing strength increased.The thermal stability of high temperature of the silicone rubber modified with nano-particle was superior to that of the silicone rubber without nano-silicon dioxide,however,the transparency of the modified rubber slightly reduced. |
