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 resin-based composite materials and a preparation method thereof. The anti-ablation coating material is yttria-stabilized zirconia, resin, Cu and SiO 2 A homogeneous mixture that is a spherical particle or spherical aggregate material. The preparation method includes powder mixing, ball milling and spray granulation. The advantage of the present invention is that the composite YSZ ceramic surface layer with exothermic specific components is used. On the one hand, the ceramic layer plays a good role in heat insulation and anti-ablation; Further improve the anti-ablation and heat insulation properties of the composite material.
