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 material structure for a rocket launch pad and its application. Specifically, an organic bottom layer, a refractory lightweight aggregate and an organic-inorganic composite surface layer are sequentially arranged on the base surface of the launch pad, wherein the refractory lightweight The material is interspersed in the organic bottom layer and the organic-inorganic composite surface layer. The organic bottom layer is composed of epoxy resin, curing agent modified polyamine and toughening agent liquid rubber, and the organic-inorganic composite surface layer is composed of organic adhesive epoxy resin, polyurethane curing agent, sand and cement. The high-temperature-resistant coating material of the invention can withstand the scouring of simulated rocket gas flow, the temperature of the metal back does not exceed 180°C, and the coating has good heat insulation performance.

Description

technical field [0001] The invention relates to a high temperature resistant coating material structure of a rocket launch pad, in particular to a structure of a high temperature resistant coating material used for coating the surface of a rocket launch pad to reduce the back temperature of a rocket launch pad and its application, which belongs to the high temperature resistant heat insulation protection field. Background technique [0002] With the development of aerospace and aerospace industry, high temperature resistant coating materials 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 material, it can insulate the metal surface, reduce thermal ablation and thermal shock, and prevent the rocket launch pad from thermal fatigue, thermal cra...
