摘要
用CPE与CaCO3复配制备出高韧性PVC复合材料,研究了CPE、CaCO3对PVC复合材料力学性能的影响。结果表明:CPE能有效提高PVC的冲击强度;CaCO3在一定用量范围内,可以提高PVC的冲击强度;CPE与CaCO3协同增韧,PVC复合材料的冲击强度可达60 kJ/m2,拉伸强度约为37 MPa,断裂伸长率可达65%。
The high toughness PVC composite was prepared by adding CPE and CaCO3 into PVC,and the effects of CaCO3 and CPE on mechanical properties of PVC were studied.The results show that： the impact strength of PVC improves with the using amount of CaCO3 in a certain range;the impact strength of PVC composite reaches to 60 kJ/m^2,the tensile strength is about 37 MPa,and then the elongation at break reaches to 65% while CPE and CaCO3 has synergistic toughening effect on PVC.
