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

Embodiment 1

[0018] The preparation of embodiment 1 high temperature resistant coating structure

[0019] 1. Preparation of organic bottom layer: mix epoxy resin SM828, curing agent polyamide 650, and toughening agent liquid rubber according to the mass ratio of 7:2:1, and then coat the rust-removed 190×120×5mm steel plate On the side surfaces, the coating thickness was 2 mm.

[0020] 2. Preparation of inorganic surface layer: firstly, mix 6-35M and 100-325M burnt gemstones evenly according to the mass ratio of 1:1, and then mix the mixed burnt gemstones with cordierite, aluminate cement and silica fume according to the mass ratio Ratio 12:3:4:1 mix. After mixing evenly, add water and stir for 3 minutes. The amount of water added is 16% (mass fraction) of the surface layer ingredients. Before the organic bottom layer is fully cured, the surface layer material is coated on the bottom layer material. A surface layer with a thickness of 8 mm is coated on the bottom layer with a thickness o...

Abstract

The invention discloses the structure and application of a high-temperature-resistant coating material for metal surfaces. The high temperature resistant coating material of the invention is composed of two layers of materials, an organic bottom layer and an inorganic surface layer. Among them, the organic bottom layer is composed of epoxy resin, curing agent polyamide and toughening agent liquid rubber. The inorganic surface consists of pyrite, cordierite, aluminate cement and silica fume. The high-temperature-resistant coating material of the invention has strong adhesion, can withstand the scouring of simulated rocket gas flow, the temperature of the metal back does not exceed 120°C, and the coating has good high-temperature gas-flow scouring performance and heat insulation performance.

Description

technical field [0001] The invention relates to a high-temperature-resistant coating structure on a metal surface, in particular to a high-temperature-resistant coating structure 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 and its application , belonging to the field of high temperature 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 cracking and thermal fracture of the ...
