纳米碳粉改性苯并噁嗪树脂性能研究

文摘为了适应苯并噁嗪树脂在高性能领域的应用,采用纳米碳粉对其进行了改性研究。结果表明,纳米碳粉对苯并噁嗪树脂的固化有催化作用,降低了苯并噁嗪树脂的固化特征温度,在一定程度上克服了苯并噁嗪树脂高温固化的不足;同时,纳米碳粉的加入,提高了苯并噁嗪树脂的弯曲性能与压缩性能,起到了增强增韧树脂的效果。

Polybenzoxazine Resin Modified by Nano-Carbon Powder

In order to adapt the polybenzoxazine resin to the application in high performance domain's,the polybenzoxazine was modified by nano-carbon powder.The results show that the nano-carbon powder has the catalytic effect on the polybenzoxazine's curing,reduces the polybenzoxazine's curing temperature,to a certain extent overcomes the shortage in curing of the polybenzoxazine at high temperature.At the same time,the nano-carbon powder improves the polybenzoxazine's mechanical property and has strengthening and toughening effect.
