Abstract

The invention discloses a compatibilizer of polyphenylene sulfide and polyamide, a polyphenylene sulfide / polyamide composite material containing the compatibilizer and a preparation method thereof. The high-performance polyphenylene sulfide / polyamide composite material of the present invention is completed in two steps: the first step: preparing a polyphenylene sulfide graft; the second step: preparing a high-performance polyphenylene sulfide / polyamide composite material; The polyphenylene sulfide graft prepared in the first step is used as the raw material for the second step. The polyphenylene sulfide graft prepared in the first step of the invention is a good compatibilizer for polyphenylene sulfide and polyamide, can obviously improve the compatibility between the two, and improve the mechanical properties of the composite material. The composite material of the invention has a wide range of applications, including automobiles, electronics, aerospace and the like.

Description

Technical field: [0001] The invention relates to the technical field of polymer material modification, in particular to a compatibilizer for polyphenylene sulfide and polyamide, a polyphenylene sulfide / polyamide composite material containing the compatibilizer and a preparation method thereof. Background technique: [0002] With the development of modern science and technology, the application and development of high-performance engineering plastic composite materials is particularly important. In the past, a single engineering plastic was used as the research object of modification, but in some special fields such as aerospace, weaponry, automobiles, etc. , a single engineering plastic can no longer meet its development needs. In recent years, high-performance, multifunctional, and specialized engineering plastic alloys obtained by physically blending or chemically grafting two or more plastics can improve or enhance the performance of existing plastics and reduce the Cost...
