摘要： 研究了纳米碳酸钙(CaCO3)和无卤阻燃剂六苯氧基环三磷腈(POP)对聚丙烯(PP)/氢氧化镁(Mg(OH)2)复合材料力学性能和燃烧性能的影响。结果表明:保持无机粒子总量90份,随着纳米 CaCO3含量的增加,材料的力学性能先提高后降低,在其含量为40份时达到最佳值。POP 的加入可减少 Mg(OH)2用量,同时可进一步提高 PP/Mg(OH)2复合材料的力学性能和阻燃性能,当 POP 用量为8份时,复合材料的断裂伸长率、拉伸强度、冲击强度和氧指数分别可达264.76%、22.34 MPa、48.65 kJ/m~2、28.2%。

Abstract: The effects of nanometerCaCOand hexaphenoxycyclotriphosphazene(POP) as a halogen- free fire-retardant on the mechanical and combustion properties of polypropylene/magnesium hydroxide(PP/Mg(OH)2)blends were studied in this paper.It showed that, when the total amount of inorganic powder kept at 90 phr, the mechanical properties of the blends increased firstly and decreased with in- creasing content ofCaCO3,with the optimum content being 40 phr.The addition of POP could reduce the loading level of Mg(OH)2 and may improve the mechanical properties and fire-retardant performance of the blends. When POP content was 8 phrelongation at breaktensile strength,impact strength and oxygen index reached 264.76%，2234MPa4865kj/m，and28.2%，respectively.

Key words: polypropylene, magnesiun hydroxide;calcium carbonate;hexaphenoxycyclotriphosp- hazene;mechanical property;flame-retardant property
