A heat-aging-resistant, low-temperature high-impact polyphenylene ether/nylon composite material and its preparation method

Abstract

The invention relates to a polyphenyl ether and nylon composite material with heat aging resistance and low-temperature high impact resistance and a preparation method thereof. The composite material is prepared from 30-60 parts of nylon 66, 20-40 parts of polyphenyl ether, 6-15 parts of compatilizer, 10-20 parts of low-temperature toughening agent, 0.4-0.8 part of thermal stabilizer and 0.4-1 part of dispersing agent. The nylon and polyphenyl ether resin alloy material has very prominent long-time thermal stability and a low-temperature high impact resistance property and is excellent in processability.

Description

technical field [0001] The invention belongs to the technical field of modified polyphenylene ether / polyamide, and in particular relates to a polyphenylene ether / nylon composite material with heat aging resistance, low temperature and high impact resistance and a preparation method thereof. The composite material is mainly used in bearing covers, electrical junction boxes, detectors, etc. in industries such as automobiles, home appliances, and electronic appliances. It has high requirements for environmental protection, safety, flame retardancy, metal corrosion resistance, low odor, strength and color. used in components. Background technique [0002] With the continuous development of industries such as automobiles, machinery, and electrical appliances, new requirements are constantly being put forward for the use of materials. Lightweight, high performance, and environmental protection have become new trends. A large number of metal materials have been replaced by engineer...

AI Technical Summary

Problems solved by technology

Foreign manufacturers such as Sabic and Asahi Kasei are the largest producers of polyphenylene ether, but the research and development of domestic polyphenylene ether / nylon composite materials is still in its infancy, and the performance of the developed polyphenylene ether / nylon composite materials is unstable. , the raw materials of polyphenylene ether / nylon composite materials of most enterprises rely on imports, and the production cost is relatively high

[0006] After searching, the Chinese patent ZL 201110008376.3, the title of the invention is: a toughened polyphenylene ether and nylon alloy and its preparation method, which discloses a polyphenylene ether / nylon composite material, but the polyphenylene ether / nylon composite material The compatibility efficiency is low, the fluidity of the product is poor, and it cannot meet the processing requirements of thin-walled parts with complex structures. At the same time, its long-term thermal aging performance and low-temperature impact performance are poor, which affects its normal use in harsh environments.
