example 1~ example 6

[0035] The polyphenylene sulfide is PPS-hb from Sichuan Deyang Chemical Co., Ltd., with a molecular weight of 48,000.

[0036] One or more mixtures of DSM's PA46, PA6T, and PA9T are selected for high-temperature resistant nylon.

[0037] Compatilizer is selected: example 1~example 2 all selects single maleic anhydride grafted SEBS for use, the maleic anhydride grafted SEBS and maleic anhydride grafted styrene both mixtures of example 3~example 6 are selected for use;

[0038] The processing aid is a 1:1 mixture of phenolic high-temperature antioxidant and stearic acid lubricant, of which the phenolic high-temperature antioxidant is Bruggemann's H161, and the stearic acid lubricant is Ciba Specialty Chemicals Calcium stearate.

[0039] The glass fiber is the alkali-free fiber of Jushi Group, 988A type, and the number of glass fibers added is controlled by adjusting the speed of the host.

Abstract

The invention provides a polyphenylene sulfide and high-temperature-resistant nylon complex and a preparation method thereof. The complex is prepared by mixing polyphenylene sulfide, high-temperature-resistant nylon, a compatibilizer, a processing aid and other components and then carrying out twin-screw melt blending extrusion on the mixture and glass fiber. The complex provided by the invention has excellent heat resistance and mechanical properties, the complex can be widely used in electronic appliances, automobiles, military industries and other fields, the complex is prepared by twin-screw extrusion, and the preparation method has the advantages of simple process, high continuous production efficiency and stable product quality.

Description

technical field [0001] The invention relates to an engineering plastic compound and a preparation method thereof, in particular to a polyphenylene sulfide and high temperature resistant nylon compound and a preparation method thereof, belonging to the field of material science. Background technique [0002] Polyphenylene sulfide is a new type of high-performance thermoplastic special engineering plastic, which has the advantages of high mechanical strength, high temperature resistance, chemical resistance, flame retardancy, good thermal stability, and excellent electrical properties. However, polyphenylene sulfide is brittle and prone to stress brittle cracks, which affects its application range. High-temperature resistant nylon series materials represented by nylon 46, 6T, 9T, etc. have excellent wear resistance, heat resistance and electrical properties, high mechanical strength, and good impact toughness. They are more and more used in machinery, electronics and other fie...
