Abstract

The invention discloses a thermal protection coating for marine environment and a preparation method thereof. The heat protection coating is composed of A component and B component; A component includes: silicone resin, coated composite heat-resistant and flame-retardant filler, reinforcing filler, composite anti-corrosion filler, pigment, adhesion promoter, anti-corrosion Mold agent, ultraviolet absorber and solvent; component B is composed of curing agent and solvent; the weight ratio of component A and component B is 100:5-30. The method comprises: firstly mixing component A and component B respectively according to the dosage of each component, and then mixing component A and component B according to the dosage ratio to prepare the heat protection coating. The coating of the present invention has the characteristics of high strength, high temperature ablation resistance, salt spray resistance, heat and humidity resistance, and ultraviolet aging resistance. It can be used with various coatings and has good compatibility. Thermal protection for missiles, sea-launched rockets, ship engines, etc. that face high temperature.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a thermal protection coating for marine environment and a preparation method thereof. Background technique [0002] Tactical missiles, which are developing toward longer range and faster flight speeds, rub against the air during flight, resulting in severe aerodynamic heating, and the surface temperature can reach 700°C. The temperature rises, causing the electronic components in the cabin to stop working due to heat. Therefore, it is necessary to use high temperature resistant thermal protective paint to protect the missile shell. Unlike box-type / barrel-launched tactical missiles or tactical missiles used in terrestrial environments, tactical missiles serving in marine environments are directly exposed to the marine environment during combat readiness and face harsh environments such as high temperature and humidity, high salt fog, and strong ultraviolet rays. Traditional heat...
