Problems solved by technology

Thermal barrier coatings have low thermal conductivity and appropriate expansion coefficient, and have good thermal insulation properties. They are relatively mature in thermal protection applications on metal-based surfaces, but their bonding strength with resin-based composite materials is low, and there are interlayers. The problem of stress mismatch, it is easy to fall off during use and lose the heat insulation effect

Abstract

The invention relates to an anti-ablation coating material for a resin-based composite material and a preparation method of the anti-ablation coating material. The anti-ablation coating material is auniform mixture of yttria-stabilized zirconia (YSZ), resin, Cu and SiO2, and the mixture is spherical particles or spherical granule materials. The preparation method of the anti-ablation coating material comprises the steps of powder mixing, ball milling and spray granulation. The anti-ablation coating material for the resin-based composite material and the preparation method of the anti-ablationcoating material have the beneficial effects that a YSZ ceramic surface layer is composited by adding specific components with heat release, so that on the one hand, the ceramic layer realizes good heat insulation and anti-ablation effects, and on the other hand, the anti-ablation and heat insulation properties of the composite material are further improved through ablation-phase gasification heat dissipation at the high temperature.
