摘要
以PVC,CPE,纳米Mg(OH)2和纳米ZnSnO3为阻燃剂对ABS进行改性,结果表明,ABS复合体系的最佳配方为:m(ABS)∶m(PVC)∶m(CPE)∶m(纳米Mg(OH)2)∶m(纳米ZnSnO3)=100∶60∶11∶3.5∶2.此时,体系的拉伸强度为36.39 MPa,缺口冲击强度为34.80 kJ/m2,氧指数为31.5%,水平燃烧达到Ⅰ级,垂直燃烧达到FV-0级,而且燃烧过程中几乎没有黑烟产生,复合体系综合性能较佳.
PVC, CPE, nano-Mg(OH) 2 and nano-ZnSnO3 were used to modified ABS. The results showed that the best prescription: m( A BS): m ( PVC): m (CPE) : m ( nano-Mg(OH)2 ): m ( nano-ZnSnO3 ) = 100: 60: 11 : 3.5: 2. The tensile strength was 36.39 MPa, the notched impact strength was 34.8 kJ/m^2, the oxygen index was 31.5% ,level firing ranked Ⅰ, vertical firing ranked FV -13 and almost there was no black smoke in the combustion process. The comprehensive performance of compound system was better.
