Abstract

Belonging to the technical field of engineering plastics, the invention relates to an enhanced semi-aromatic nylon / liquid crystal polymer alloy material and a preparation method thereof. The material is prepared from the following components by weight: 60-70 parts of semi-aromatic nylon, 5-10 parts of a thermotropic liquid crystal polymer, 30-40 parts of a filling reinforcer, 5-10 parts of a compatilizer, 0.5-1 part of a lubricant, and 0.5-1 part of an antioxidant. The enhanced semi-aromatic nylon / liquid crystal polymer alloy material provided by the invention has the characteristics of high strength, high rigidity and high temperature resistance, simple preparation process and low cost, and the preparation method for the semi-aromatic nylon / liquid crystal polymer alloy material can achieve good economic benefits.

Description

technical field [0001] The invention belongs to the technical field of engineering plastics, and relates to a reinforced semi-aromatic nylon / thermotropic liquid crystal polymer alloy material and a preparation method thereof. Background technique [0002] Semi-aromatic nylon is prepared by melt polycondensation of dicarboxylic acid with aromatic ring and aliphatic diamine. At present, there are mainly PA6T, PA6I, PA8T, PA9T, PA9I, PA10T, PA12T, etc., which are mainly composed of polyamide molecules. Aromatic rings are introduced into the chain, which improves heat resistance and mechanical properties, and reduces water absorption. It is a resin with high heat resistance between general-purpose engineering plastic nylon and high-temperature-resistant engineering plastic PEEK, and can be widely used in automobiles , construction, electronic appliances and household appliances industries. [0003] Liquid crystal polymers appear in a liquid crystal state because heating destroy...
