摘要/Abstract

摘要： 为提高聚丙烯(PP)阻燃性能,以三聚氰胺磷酸盐为酸源兼气源、双季戊四醇为碳源构成膨胀阻燃体系,添加不同比例的类沸石咪唑酯骨架材料(ZIF-8)与生物质炭(BC)制备的杂化材料(ZIF-8/BC)为协效剂,制备无卤膨胀阻燃PP复合材料,研究材料的燃烧性能、力学性能和热稳定性等。结果表明:所构成的膨胀阻燃体系能有效提高PP的阻燃性能,未添加ZIF-8/BC时氧指数可达31.4%,拉伸强度为17.37 MPa;ZIF-8/BC的加入使复合材料氧指数有所降低,但能提高复合材料的力学性能,添加ZIF-8∶BC质量比为1∶2的ZIF-8/BC,材料氧指数、拉伸强度分别为27.2%、19.87 MPa;ZIF-8/BC的添加能提高复合材料的残炭量,且该量随BC含量增加而增大,ZIF-8/BC协效剂有利于形成致密炭层结构和抑制烟气释放。

Abstract: To improve the flame retardant properties of PP, melamine phosphate was used as an acid source and a gas source, dipentaerythritol was used as a carbon source to form an intumescent flame retardant system, and different proportions of ZIF-8/BC created by ZIF-8 material and BC were added into the system as synergist. The combustion properties, mechanical properties and thermal stability of the new halogen-free intumescent flame retardant composite were studied. The results indicate that the intumescent flame retardant system could effectively improve the flame retardancy of PP, and without the addition of ZIF-8/BC the oxygen index increases to 31.4%, while the tensile strength decreases to 17.37 MPa, that the addition of ZIF-8/BC slightly reduces the oxygen index of the composites, but improves the mechanical properties of the composites, that when ZIF-8/BC with a ratio of ZIF-8∶BC of 1∶2 is added, the oxygen index and tensile strength of the material are 27.2% and 19.87 MPa respectively, and that addition of ZIF-8/BC could increase the carbon content of composites, and it increases with the BC content, and that ZIF-8/BC as the synergistic agent has a positive effect on formation of dense carbon layer structure and smoke suppression.
