Elastic fluorosilicone thermal insulation coating for aerogel thermal insulation system and preparation method of elastic fluorosilicone thermal insulation coating

The invention relates to the technical field of composite materials, and discloses an elastic fluorosilicone thermal insulation coating for an aerogel thermal insulation system and a preparation method of the elastic fluorosilicone thermal insulation coating. The coating provided by the invention comprises modified hollow glass beads, an elastic water-based fluorocarbon emulsion, a silicon resin emulsion, a light stabilizer and the like. Wherein the silane coupling agent and the acrylate are used for modifying the hollow glass beads, so that the compatibility of the hollow glass beads and the fluorosilicone resin is improved, and the modified glass beads are compounded with the fluorocarbon emulsion, the silicone resin, the histamine type light stabilizer and the like to achieve a synergistic effect, so that the comprehensive performance of the coating is improved. The coating provided by the invention is uniform in paint film and high in coating strength, and the problems that the coating is aged and cracked
