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
[0003] The rocket launch pad can be thermally protected by using special high-temperature-resistant coating materials and structures, but at present, there are no relevant reports on the technology for thermal protection of the launch pad

Abstract

The invention discloses a structure and applications of a high-temperature-resistant coating material for steel structure surface. The high-temperature-resistant coating material is composed of an organic layer, a shaped firebrick layer, an organic layer, and an amorphous refractory material layer. The two organic layers have the same components and are composed of epoxy resin, a polyamide curing agent, and a toughening agent (liquid rubber). The firebrick is clay-based firebrick. The amorphous refractory material is composed of flint clay, cordierite, aluminate cement, and silica fume. The adhesion force of the provided high-temperature-resistant coating material is strong, which can sustain the washing of rocket imitated combustion-gas stream. The metal backside temperature does not exceed 120 DEG C, and the coating has an excellent performance on resisting high-temperature combustion-gas stream brushing and thermal insulation property.

Description

technical field [0001] The invention relates to a high-temperature-resistant coating structure on the surface of a steel 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 the launcher and protect the surface of the steel structure of the rocket launcher. The application belongs to the field of high temperature resistance and 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 launch pad is coated with high-temperature resistant coatings, it can insulate the metal surface, reduce thermal ablation and thermal shock, and prevent thermal fatigue, thermal crackin...
