Abstract

The invention relates to a nylon glass fiber reinforced alcoholysis-resistant material and belongs to the technical field of hydrolysis-resistant materials. The nylon glass fiber reinforced alcoholysis-resistant material comprises, by weight, 50-78 parts of nylon resin, 25-35 parts of glass fiber, 0.2-1.0 part of antioxidant, 1.0-3.0 parts of glass fiber exposure preventive adjusting auxiliary, 0.1-1.0 part of therostabilizer, 0.1-1.0 part of alcoholysis-resistant auxiliary and 1.0-2.0 parts of toughening agent. The nylon glass fiber reinforced alcoholysis-resistant material has excellent alcoholysis-resistant performance and high impact resistance and size stability and ensures to be free of stress cracking at an assembly joint. Pressure pulse experiments show that products made of the material can realize zero cracking and zero leaking for 0.25 million times.

Description

technical field [0001] The invention relates to the technical field of hydrolysis-resistant materials, more specifically, the invention relates to a nylon glass fiber-reinforced alcoholysis-resistant material, especially a nylon material used in an automobile radiator water chamber and a production method thereof. Background technique [0002] In the existing technology, the water chamber nylon special materials used in high-end cars and large trucks are mainly produced in Japan, Europe and the United States and other countries and regions around the world, such as DuPont, domestic manufacturers include Jiangsu Jinlun and Kingfa Technology, etc. The production of PA66GF30 water chamber material, however, the domestic output is small and there is still a certain gap between the performance and foreign products. [0003] Chinese Invention Patent Publication 200910041490.9 discloses a method for preparing an alcoholysis-resistant nylon composite material. The nylon composite ma...
