Abstract
The invention discloses a high temperature resistant combustion-gas stream coating for a rocket launching tower and a diversion trench. The coating comprises hybrid silicon resin, tetraethylortho silicate, ethyl borate, metallic oxide and non-metallic oxide packing, metal powder and a solvent, wherein the metal powder contains aluminum powder. Due to the high temperature resistant combustion-gas stream coating for the rocket launching tower and the diversion trench, the metal structures of the rocket launching tower and the diversion trench can be prevented from washing and high-temperature corrosion of high-temperature combustion-gas streams, thereby being conducive to keeping reasonable strength of a matrix steel structure, so that the service lives of the rocket launching tower and the diversion trench are prolonged; the high temperature resistant combustion-gas stream coating for the rocket launching tower and the diversion trench is suitable for the environments in high humidity, high salt fog and high ultraviolet radiation, has strong corrosion resistant performance, and meets the requirement on the protection of launcher matrix coatings on basis of developing rocket launching bases to coastal regions at which the transport and the launch are more convenient; the coating is a dry normal coating and is simple and convenient in construction; and the coating is relatively friendly to the environment.
Description
technical field [0001] The invention relates to the technical field of coatings, in particular to a high-temperature gas flow-resistant coating for a rocket launch tower and a diversion tank. Background technique [0002] With the rapid development of aerospace, aviation, weapons and other industries, the requirements for high temperature resistance of special components are getting higher and higher. High-temperature-resistant coating materials are currently widely used due to their good performance in large-scale construction processes and without greatly reducing product strength. The matrix material of the rocket launcher and the diversion tank is metal or metal alloy material, and a small number of diversion tanks are made of refractory cement material. In order to protect these materials from the erosion of high-temperature gas flow and high-temperature oxidation, and to deal with various harsh natural conditions, the current method is to coat one or more layers of pr...
