Problems solved by technology

[0002] Polyamide, the English name PA, is a general term for high polymers containing amide groups in the repeating unit of the main chain of the macromolecule. PA is tough, wear-resistant, self-lubricating, and has a wide temperature range and has become a widely used in industry. With the rapid development of society, people have developed PA66, PPA, PA6T materials, and also invented some preparation methods of PA66, PPA, PA6T related copolymers. With the rapid development of science and technology, people's requirements for materials are getting higher and higher. As a result, the high temperature resistance and strength of the existing PA66, PPA, PA6T materials and related copolymers cannot meet people's requirements

Abstract

The invention discloses a preparation method of a high-temperature-resistant and high-strength material. The high-temperature-resistant and high-strength material is prepared by, by weight, 45-50 parts of polyhexamethylene adipamide, 55-60 parts of polyhexamethylene terephthalamide, 30-35 parts of polyphthalamide, 60-80 parts of caprolactam, 20-25 parts of methyl silicone oil, 15-20 parts of m-cresol, 1-2 parts of catalyst and 1-2 parts of lubricating agent. The preparation method has the advantages that the prepared material is high in density, high in strength, low in in crystallinity and melting point, convenient in forming, low in water absorption, wide in application range and high in heat resistance; little equipment is needed in the preparation process, the preparation cycle is short, preparation convenience is achieved, and the use effect of the prepared material is better than that of a material prepared by a traditional manner, people's requirements can be satisfied, and promising application prospect is achieved.

Description

technical field [0001] The invention relates to the field of high-temperature-resistant materials, and more specifically, relates to a preparation method of high-temperature-resistant high-strength materials. Background technique [0002] Polyamide, the English name PA, is a general term for high polymers containing amide groups in the repeating unit of the main chain of the macromolecule. PA is tough, wear-resistant, self-lubricating, and has a wide temperature range and has become a widely used in industry. With the rapid development of society, people have developed PA66, PPA, PA6T materials, and also invented some preparation methods of PA66, PPA, PA6T related copolymers. With the rapid development of science and technology, people have more and more requirements for materials. As a result, the high temperature resistance and strength of the existing PA66, PPA, PA6T materials and related copolymers cannot meet people's requirements. Contents of the invention [0003] ...
