摘    要:分析比较了三种不同的UPVC/nano-CaCO3复合材料界面性质对力学性能的影响。结果表明,界面性质和nano-CaCO3用量均对力学性能有明显影响。在一定范围内,增加界结合强度,可提高UPVC的屈服强度与模量,却使材料的缺口冲击强度有所降低;增加nano-CaCO3的用量,可提高UPVC抗冲击性能,却会降低复合材料的屈服强度。

关 键 词:UPVC/nano-CaCO3复合材料  界面性质  力学性能  硬聚氯乙烯  纳米碳酸钙

Abstract:We analyze and compare the relationship between interfacial adhesion and mechanical properties of three different kinds of UPVC/nano CaCO 3 composite material. It reveals that both interfacial adhesion and quantity of nano CaCO 3 used influence their mechanical properties obviously. To a certain extent, increasing the interfacial adhesion strength, we can elevate the yield stress and modulus of elasticity of the UPVC, but reduce the impact strength. Increasing the nano CaCO 3 used, we have increased impact strength but decreased yield stress.
Keywords:vinyl chloride  nanometer CaCO  3  interfacial adhesion  mechanical  property
