Abstract

The invention relates to a poly(nonamethyleneterephthalamide) material and a preparation method thereof. The composite material comprises the following components in part by weight: 30 to 50 parts of poly(nonamethyleneterephthalamide) (PA9T), 8 to 20 parts of polyamide (PA6, PA66), 10 to 15 parts of main flame retardant, 3 to 5 parts of auxiliary flame retardant, 30 to 45 parts of filler intensifier, 0.2 to 0.6 part of antioxidant, 0.2 to 0.8 part of lubricant and 0.3 to 0.6 part of nucleating agent. In the method, the polyamide is added into the material to improve the defect of poor flowability of the poly(nonamethyleneterephthalamide), so the manufacture temperature and difficulty can be greatly reduced; because of high price of the PA9T, nylon is introduced to greatly reduce the production cost, realize profit optimization; and by selecting different types of glass fibers as the filler intensifier, the comprehensive performance of the material is greatly improved. The PA9T intensified modified material has simple preparation process, low cost, high profit and excellent economical benefit.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-performance, low-cost modified and reinforced polynonanediamine terephthalamide material and a preparation method thereof. Background technique [0002] Polynonanediamine terephthalamide (PA9T) is a new type of high-temperature-resistant high-performance nylon material that was successfully developed and mass-produced by DuPont in the world for the first time in the world. The trade name is Zytel. High, high strength, excellent electrical properties and other advantages. Polynonanediamine terephthalamide (referred to as PA9T) is a semi-aromatic polyamide formed by melting polycondensation of nonanediamine and terephthalic acid. It has relatively high crystallinity and fast crystallization speed (up to 75% crystallinity) ), so the melting point is higher (308°C), the glass flower transition temperature is 126°C, the heat distortion temperature is also high, and t...
