摘    要:采用模压成型的方式、通过实验探索玻璃纤维(GF)含量及偶联剂处理对聚氯乙烯(PVC)/稻壳木塑复合材料的力学特性和耐磨性的影响。实验结果表明:PVC/稻壳木塑复合材料的硬度随GF含量增加呈现先减小后增大的趋势。GF含量在15%以下时,随着GF用量的增大,木塑复合材料的拉伸强度与冲击强度总体上随之变大,超过15%则随GF含量增大而减小。而弯曲强度出现先减后增的趋势,弯曲弹性模量则与之相反。木塑复合材料的耐磨损性在GF含量为15%时最佳,摩擦系数在10%时最大。合适的偶联剂处理能增强木塑复合材料的力学性能和耐磨性。其中γ–氨丙基三乙氧基硅烷(KH550)的增强效果比较好,钛酸酯不能提高PVC/稻壳木塑材料的力学性能和耐磨性。

关 键 词:玻璃纤维  聚氯乙烯  木塑复合材料  偶联剂  力学性能  耐磨性

Abstract:With the method of molding press experiments,the effect of glass fiber (GF) content and coupling agent dispose on the mechanical properties and friction and wear properties of the PVC / rice husk wood-plastic composites were explored.Experimental results show that the hardness of material appear a trend of reducing first then increasing with GF content increase.When GF content is below 15%,with the increase of the content of GF,the tensile strength and impact strength of PVC/rice husk wood-plastic composites increase.With the increase of GF content,when it is more than 15%,the bending strength appear a trend of reducing first then increasing,and the flexural modulus is the opposite.The wear resistance of composites is best at GF content is 15%,the friction coefficient is biggest at GF content is 10%.The suitable coupling agent dispose can significantly improve the mechanical behavior and friction and wear properties of PVC / rice husk wood-plastic composites.3-Aminopropyltriethoxysilane (KH550) has cracking effect.Titanate can not improve mechanical behavior and friction and wear properties of the composites.
Keywords:glass fiber  polyvinyl chloride  wood-plastic composite  coupling agent  mechanical property  abrasion resistance
