| 摘 要： | 分别研究了1 250目、2 500目CaCO3以及甲基丙烯酸-丁二烯-苯乙烯共聚物(MBS)对聚氯乙烯(PVC)力学性能的影响;并且选用15%MBS与1 250目CaCO3复配制备出了高韧性的PVC材料。结果表明:MBS能有效提高PVC的冲击强度;1 250目CaCO3与2 500目CaCO3相比,更易于分散,增韧的效果更好;MBS与1 250目CaCO3协同增韧,使PVC冲击强度达120 kJ/m2,拉伸强度约为37 MPa,断裂伸长率在40%左右。

| Abstract: | The effect of 1 250 mesh size calcium carbonate(CaCO3)and 2 500 mesh size CaCO3 and MBS on mechanical properties of polyvinyl chloride(PVC)were studied in the paper.And high toughness PVC was prepared by adding 15%MBS and 1 250 mesh CaCO3.It was found that impact strength of PVC was improved effectively by MBS.Compared with 2 500 mesh size CaCO3,1 250 mesh CaCO3 was easier to disperse and more effective to toughen PVC.When MBS and 1 250 mesh CaCO3 were added together,the impact strength of PVC was over 120 kJ/m2,tensile strength was about 37 MPa,elongation at break was about 40%. |
