Problems solved by technology

In foreign countries, the Ariane rocket launch platform of the European Space Agency in Guyana, South America is a concrete launch platform. This type of launch platform constructed of inorganic non-metallic materials has better gas purging and ablation resistance than organic ablation coatings, but the disadvantage is that it is thick. , heavy, and the launch pad cannot be moved

Abstract

The invention discloses a high temperature-resistant coating structure for a rocket launcher and its application. The high temperature-resistant coating structure is composed of an organic base layer, a fire refractory light aggregate and an amorphous fire refractory material layer. A part of the fire refractory light aggregate is embedded in the organic base layer and a part of the fire refractory light aggregate is embedded in the amorphous fire refractory material layer. The organic base layer is composed of epoxy resin, a curing agent polyamide and a toughener liquid rubber. The amorphous fire refractory material layer is composed of mullite, cordierite, aluminate cement and silica fume. The high temperature-resistant coating structure can withstand rocker simulated gas flow erosion, the metal backside temperature does not exceed 80 DEG C, and the coating has good high temperature gas flow erosion resistance and heat insulation performances.

Description

technical field [0001] The invention relates to a high-temperature-resistant coating structure, in particular to a high-temperature-resistant coating structure used for coating the surface of a rocket launcher to reduce the back temperature of a rocket launcher and an application thereof, belonging to the field of high-temperature-resistant heat insulation protection. Background technique [0002] With the development of aerospace and aerospace industry, high temperature resistant coatings have opened up new application fields. In addition to the thermal protection of the aircraft itself, thermal protection measures have also been added to ground facilities such as rocket launch pads in China. If the rocket launch pad is coated with a high temperature resistant coating, it can insulate the metal surface, reduce thermal ablation and thermal shock, and prevent the rocket launch pad from thermal fatigue, thermal cracking and thermal fracture under the action of multiple thermal...
