The present invention relates to a kind of high glow wire halogen-free and environment-friendly flame retardant nylon 66. By introducing a halogen-free flame retardant containing phosphorus and nitrogen components, the flame retardant mechanism of gas phase and condensed phase is formed together to achieve the purpose of flame retardant. Zirconium is loaded on the surface of graphene oxide, which not only increases the thermal oxidation stability of graphene oxide, but also α-zirconium phosphate can also play a role in catalyzing carbon formation, which helps to synergistically improve the thermal stability and flame retardancy of polymer composites Performance: The present invention converts the transition phase zirconium phosphate into α-zirconium phosphate by the gas and water vapor generated by the instantaneous microwave heating and decomposition, and combined with the dispersion effect of the surfactant, the zirconium phosphate can be uniformly dispersed in the zirconium phosphate. The surface of graphene oxide can be produced in large quantities, and solves the problems of complex preparation process and high energy consumption of graphene-supported zirconium phosphate composite materials. In addition, due to the high specific surface area and surface functional groups of graphene oxide, it can play To a certain degree of water absorption, to avoid the destructive effect of water molecules on nylon 66 in a humid environment. |
