Problems solved by technology

Experimental results show that the mass ablation rate of the final product prepared in the examples is 0.0510-0.0528g / s, but the preparation method is complex in process, requires precise equipment, high production cost, and is not suitable for industrial production
[0007] At present, there is no good solution to the problem of easy ablation of polyphenylene sulfide materials in the micro-arc oxidation process. It is a good way to improve the heat resistance and ablation resistance of polyphenylene sulfide materials by modifying them. Feasible ideas, researchers have conducted a lot of research, but there are still many problems such as complex preparation process and high cost, so it is urgent to develop a polyphenylene sulfide composite material that can withstand the high temperature and high pressure produced by the micro-arc oxidation process

Abstract

The invention discloses an ablation-resistant polyphenylene sulfide composite material and a preparation method thereof, belonging to the technical field of ablation-resistant materials. The polyphenylene sulfide composite material mainly includes polyphenylene sulfide resin, alkali-free glass fiber and poly-m-xylylene adipamide. The preparation method includes melting and kneading polyphenylene sulfide resin and alkali-free glass fiber first, then adding polym-xylylene adipamide for secondary melting and kneading, cooling and solidifying, and pelletizing to obtain the target product . The polyphenylene sulfide composite material obtained by the preparation method can withstand the action of high temperature and high pressure generated by the micro-arc oxidation process, has good ablation resistance, and has a simple preparation process.

Description

technical field [0001] The invention belongs to the technical field of ablation-resistant materials, in particular to an ablation-resistant polyphenylene sulfide composite material and a preparation method thereof. Background technique [0002] Micro-arc oxidation, also known as micro-plasma oxidation and plasma electrolytic oxidation, is a new technology for in-situ growth of ceramic films on the surfaces of aluminum, magnesium, titanium and other metals. In the process of micro-arc oxidation, the metal surface relies on arc discharge to generate instantaneous high temperature and high pressure, and the base metal is directly oxidized and sintered into an oxide ceramic film layer. Features such as high temperature shock, wear resistance and electrical insulation. The technology has the characteristics of simple operation, no pollution and high efficiency, and has broad application prospects in the fields of aerospace, electronics and machinery. [0003] For the shell part...
