摘要
采用新型稀土偶联剂为主要处理剂对碳酸钙(CaCO_3)表面进行活化处理,并对其填允PVC体系的冲击性能、拉伸性能及热机械性能进行了研究。结果表明:稀土偶联剂处理CaCO_3填充到PVC中可明显地改善共混体系的加工性能,冲击性能和热机械性能在一定的填允量范围内也有所改善,同钛酸酯偶联剂和铝酸酯偶联剂一样,它是一种适出于CaCO_3表面活化的偶联剂,而且在某些方面表现较优。
The surface activation of calcium carbonate (CaCO3) was done with new rare -earth coupling agent, and impact, tensile and thermomechanical properties of PVC system filled with CaCO3 were studied. The results showed that the processing property of the blend system was improved obviously and the impact and thermomechanical properties were enhanced to some extent in certain filling range by filling PVC with the CaCO3, this new rare -earth coupling agent was suitable for surface activated coupling agent of CaCO3 as same as titanate and aluminat coupling agent, it even better in some aspect.
