Abstract

The invention discloses a hydrolysis-resistant nylon composite material and a preparation method thereof. The material comprises the following components in percentage by weight: 45-75 percent of nylon resin, 0.1-1 percent of hydrolysis resisting agent, 0.1-1 percent of heat stabilizer, 0.1-1 percent of antioxidant, 0.1-1 percent of coupling agent, 0.1-5 percent of lubricant and 20-50 percent of hydrolysis-resistant glass fiber. The hydrolysis-resistant nylon composite material solves the difficulties of the water assistance technique, improves the heat resisting temperature and the hydrolysis resistance of nylon, and maintains higher mechanical performance at the same time of obtaining high-temperature resistance and hydrolysis resistance.

Description

[technical field] [0001] The invention relates to the field of polymer materials, in particular to a hydrolysis-resistant nylon composite material and a preparation method thereof. [Background technique] [0002] As the most important variety of engineering plastics, nylon has strong vitality, mainly because it achieves high performance after modification, and secondly, the automobile, electrical appliance, communication, electronics, machinery and other industries themselves have more and more high-performance requirements for products. strong. The rapid development of related industries has promoted the process of high-performance engineering plastics. With the development of injection molding technology, a new injection molding process, water-assisted process, has been proposed on many occasions. This process has brought great benefits to customers. Benefits, it can greatly shorten the injection molding time which also reduces the cost accordingly. This process also has...
