Abstract

The invention relates to the technical field of polymer materials, in particular to a halogen-free high-temperature nylon PA6T reinforced flame-retardant composite material and a preparation method thereof. The composite material includes the following raw materials in parts by weight: 20-60 parts of PA6T, 3-20 parts of PA6, 8-22 parts of flame retardant, 20-60 parts of glass fiber, 1-10 parts of compatibilizing and toughening agent, 0.1-1.0 parts of antioxidant, and 0.1-1.0 parts of lubricant. The composite material of the present invention aims at the shortcomings of high melting point and difficult processing of PA6T. PA6 is introduced. Because PA6 has good fluidity and amide groups of nylon family, it can be better integrated with PA6T materials, thereby increasing its fluidity. The processing temperature is greatly reduced, the degradation of the flame retardant and additives in the system is solved, and the extrusion granulation is smoother.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a halogen-free high-temperature nylon PA6T reinforced flame-retardant composite material and a preparation method thereof. Background technique [0002] Polyhexamethylene terephthalamide (referred to as PA6T) is a new type of high-temperature-resistant, high-performance special engineering plastic that was first developed and mass-produced by Mitsui Chemicals in Japan. It has the advantages of good stability, excellent chemical resistance and good molding performance. PA6T is a semi-crystalline thermoplastic semi-aromatic polyamide, commonly known as aromatic high-temperature nylon. It is a high-temperature-resistant material with a melting point between 310-325°C and a heat distortion temperature between 260-280°C. Between, its melting point is higher than PA46 and PPS. Compared with PA66, PA6T has higher mechanical properties, heat resistance, water absorption is mu...
