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, and belongs to the technical field of ablation-resistant materials. The polyphenylene sulfide composite material mainly comprises the following components: polyphenylene sulfide resin, alkali-free glass fibers and polyadipoyl m-xylylenediamine. The preparation method comprises the following steps: firstly melting and mixing polyphenylene sulfide resin and alkali-free glass fibers, then adding polyadipoyl m-xylylenediamine for secondary melting and mixing, cooling, curing anddicing to obtain a target product. The polyphenylene sulfide composite material obtained by the preparation method can bear high-temperature and high-pressure effects generated in a micro-arc oxidation process, has good ablation resistance, and is simple in preparation process.

Description

technical field [0001] The invention belongs to the technical field of ablation-resistant materials, and in particular relates 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 surface of aluminum, magnesium, titanium and other metals. In the micro-arc oxidation process, the metal surface relies on arc discharge to generate instantaneous high temperature and high pressure, and directly oxidizes and sinters the base metal into an oxide ceramic film layer. High temperature impact, wear resistance and electrical insulation and other characteristics. This 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...
