Light-cured organic silicon heat-proof coating and preparation method thereof

The invention belongs to the field of thermal protection of aerospace crafts, and particularly relates to a light-cured organic silicon heat-proof coating and a preparation method thereof. The light-cured organic silicon heat-proof coating comprises the following raw materials: a reinforcing body, a matrix and a functional filler. According to the technical scheme, the characteristics of high temperature resistance, ablation resistance, short preparation period, high curing efficiency, low toxicity, environment friendliness, excellent performance and the like of the organic silicon material are utilized, and meanwhile light and heat (normal temperature) dual curing of the silicon-based resin is utilized, so that the defects that traditional room-temperature curing time is too long, equipment size and shape are limited, and a construction mode is relatively single can be overcome. The light-cured organic silicon heat-proof coating material obtained by the invention can be used for a long time in an oxidizing a
