摘　　要：以液态高分子改性剂(LMM)、CaCO3及交联剂为原料,采用机械力化学改性的方法制备出表面交联包覆改性的CaCO3(记作CLCC)。将CLCC与聚氯乙烯(PVC)进行熔融共混制备出高耐热抗冲PVC/CLCC复合材料。当CLCC用量为5份时,PVC/CLCC复合材料的耐热性和抗冲击性能最佳,此时复合材料的的玻璃化转变温度出现最大值104.6℃,缺口冲击强度达5.8kJ/m2。The surface cross-linked and modified CaCO3（defined as CLCC） was prepared by mechanochemical method with liquid macromolecular modifier （LMM）, CaCO3 and cross-linking agent. The PVC/CLCC composites with high heat resistance and anti-impact were also prepared through melt-blending CLCC with PVC resins. When the content of CLCC is 5 phr, the heat resistance and anti-impact property of the PVC/CLCC composite achieve maximum value. In this case, the glass transition temperature and notched impact strength of the composite respectively reach the maximum 104.6 ℃ and 5.8 kJ/m^2.
