Embodiment Construction

[0028] The production method of the present invention is illustrated as follows, but the present invention is not limited to the following examples.

[0029] raw material:

[0030] PPE: Poly(2,6-dimethyl-1,4-phenylene ether), Ruicheng Branch of Bluestar Chemical New Materials Co., Ltd., LXR050, with an intrinsic viscosity of 0.50dl / g;

[0031] PA66: Basf 1310-11 NF2001;

[0032] PA6: Basf 8270HS;

[0033] LCP: Ticona A950;

[0034] Compatibilizer: SMA 1000;

[0035] Nucleating agent: Clariant Cav 102;

[0036] Impact modifiers: SEBS G1651;

[0037] Antioxidant: Ciba 1010: 168=1:2;

[0038] First mix polyphenylene ether, liquid crystal polymer resin, compatibilizer, impact modifier, some antioxidants and other additives through a high-speed mixer, and then directly enter the twin-screw extruder through the main feed, while PA66 and PA6 resin, nucleating agent and other antioxidants are fed into the twin-screw extruder through side feeding, and then packag...

Abstract

The invention discloses a rapid molding high heat-resistant polyamide-polyphenyl ether alloy and a preparation method thereof. The weight ratios of raw materials of the rapid molding self-reinforced high heat-resistant polyamide-polyphenyl ether alloy are 20-75 parts of a polyphenyl ether resin, 10-80 parts of a polyamide resin, 1-35 parts of a liquid crystalline polymer resin, 0.1-3 parts of a nucleating agent and 1-10 parts of a compatilizer. Compared with a conventional alloy, the rapid molding self-reinforced high heat-resistant polyamide-polyphenyl ether alloy has a series of the advantages of low specific gravity, good surface gloss, high mechanical strength, good heat resistance, good chemical resistance, short molding period, etc.

Description

technical field [0001] The invention belongs to a high-performance polymer composite material, in particular to a rapid prototyping high heat-resistant polyamide-polyphenylene ether alloy and a preparation method thereof. Background technique [0002] With the development of modern science and technology, the performance requirements of materials are getting higher and higher. For engineering plastics, it is expected to have high strength, high temperature resistance, low density and good processing performance, especially in aviation, aerospace, electronics, petroleum machinery, textile machinery, printing and dyeing machinery, office equipment, Medical equipment, auto parts and other fields. [0003] Polyphenylene ether (hereinafter referred to as PPE) has a series of advantages such as high glass transition temperature Tg, high mechanical strength, high heat distortion temperature HDT, good ductility, good electrical properties, and good dimensional stability. There are...
