Abstract

The invention relates to a formula and a process method of a high-performance special nylon material, in particular to a formula and a process method for improving the wear resistance of a special nylon PA9T material through filling modification. The formula comprises 55%-70% of a PA9T material, 15%-30% of a glass fiber material, 1%-10% of graphite, 0.5%-1.5% of an antioxidant, 0.5%-1.5% of a heatstabilizer, 0.5%-1.5% of a coupling agent and 0.5%-1.5% of other auxiliaries. The materials are subjected to premixing and twin-screw extrusion granulation in proportion, and the prepared nylon material has higher wear resistance than common nylon materials. On the basis of ensuring the high strength and high modulus of the original PA9T material, the wear resistance of the composite material iseffectively enhanced, and the comprehensive properties of the composite material are improved. The high-wear-resistance special nylon material has the advantages in the field of industrial manufacturing of products of the same type, especially in the field of industrial manufacturing with high requirements for wear resistance, and has wide application prospects and development potential.

Description

technical field [0001] The field that the present invention relates to includes a formula and a process method of an organic polymer composite material, more precisely, a formula and a process method for improving the wear resistance of special nylon PA9T materials through filling modification. Background technique [0002] PA9T is a semi-aromatic special nylon material developed by Kuraray Corporation of Japan. Compared with ordinary nylon materials, due to the introduction of aromatic rings in the molecular chain, PA9T has a significantly higher glass transition temperature, enhanced heat resistance, lower water absorption, and good dimensional stability and solvent resistance. In terms of mechanical properties, the strength and modulus of PA9T are much higher than ordinary nylon materials. In addition, the molecular chain of PA9T has good flexibility, and the molecular chain structure is regular, the crystallization rate is fast, and the crystallinity is high, so PA9T al...
