Thermal protection must be provided between the engine composite housing and the internal filler in such harsh thermal environments; meanwhile, in the process of high-speed flight in the atmosphere, static electricity is generated by friction between the missile and air, the engine propellant is susceptible to the static electricity, and then anti-static measures must be taken between the composite material shell and the internal filling materials of the engine. In order to ensure the successful flying of the missile, a paint layer with heat resistance and static resistance is developed in the Chinese space 806. At the present stage, glue is dipped manually through a long bamboo pole with a head part bound with fiber cloth, and the glue is repeatedly coated on the inner wall of the shell of the engine. The paint has the characteristics of high solid content, high viscosity, light weight, low density and low spraying thickness. The requirements on the spraying process parameters and the spraying operation parameters are high, the glue solution is easy to sag due to the fact that manual painting is not controlled in place, the leveling property is poor, the stability is poor, and the coating quality cannot meet the requirements.

With the development of economy and the progress of technology, the application of the robot is gradually popularized, the robot enters the household appliance industry, and the robot is applied on a large scale on nearly 30 automatic coating production lines of more than twenty enterprises. In the aspect of coating military products, the technology is gradually increased, but the forming process of manual coating is generally adopted in China for special heat-proof coatings with higher precision and higher viscosity, the coating space is narrow, the quality stability of the coatings is poor, and the coating efficiency is low.
