摘要

采用模压成型法制得复合材料,并进行摩擦磨损性能的测试,研究稻壳用量、纳米CaCO₃含量、偶联剂对聚氯乙烯/稻壳木塑复合材料耐磨性能的影响。结果表明:当稻壳用量为40%时,木塑复合材料磨损量最少,摩擦系数较大;当添加5%纳米CaCO₃时,复合材料的耐磨性能较为优良;采用偶联剂处理有助于其耐磨性能的提高,其中硅烷KH-550的作用尤为明显,钛酸酯对复合材料耐磨性能的提升没有良好的效果。

Abstract

By blending nano-CaCO₃ particles instead of rice husk fiber,then the composite material was composed through mixed PVC matrix.A series of friction and wear properties were studied,including the effect of nano CaCO₃ particle content and the type of coupling agent on the properties of friction and wear.Results shown that matching scheme for 40% of the rice husk and 60% of PVC mixed system was perfected compared with other scheme.When the content of nano-CaCO₃ particles was 5%,the composite had better friction and wear properties.And the coupling agent treated hybrid materials due to its better interfacial compatibility and had better mechanical properties.The effect of silane coupling agent was more significant.
