Abstract

The present invention relates to thermoplastic polymer material, and is especially glass fiber reinforced no-halogen flame retardant nylon-66 and its preparation process. The glass fiber reinforced no-halogen flame retardant nylon-66 is prepared with nylon-66 resin 40-50 weigh portions, long glass fiber 23-28 weigh portions, toughener 0-7 weigh portions, M-MPP 20-26 weigh portions, antioxidant-1010 0.1-1 weigh portion, and processing agent 0.2-1.5 weigh portions. The preparation process includes the steps of mixing the said materials in a double screw extruder, smelting, extruding, drawing into strip, cutting into grains, drying and packing. The glass fiber reinforced no-halogen flame retardant nylon-66 has the advantages of high flame retarding performance, high mechanical performance and high heat resistance.

Description

technical field [0001] The invention relates to a thermoplastic polymer fiber reinforced material and a preparation method thereof, in particular to a glass fiber reinforced halogen-free flame-retardant nylon 66 material and a preparation method thereof. Background technique [0002] Glass fiber reinforced halogen-free flame-retardant nylon 66 is a very important halogen-free flame-retardant engineering plastic. It is mainly used in the fields of electronic devices and electrical devices, auto parts and so on. Research on high-performance glass fiber reinforced halogen-free flame-retardant nylon 66 is an important direction for the development of new materials today. In the face of increasingly stringent environmental protection and safety requirements, as well as the continuous development of electronics, electrical appliances, automobiles, mechanical instruments and other industries, the requirements for halogen-free, low-smoke, low-toxicity flame-retardant materials are ...
