Abstract
The invention belongs to the field of coating technology, and especially relates to an environment-friendly room temperature curing organic silicon high-temperature resistant coating. The environment-friendly room temperature curing organic silicon high-temperature resistant coating is composed of A component and B component. A component comprises organic silicon resin, a pigment, a thermal insulation material, a high-temperature binding material, and a rust-resisting material with the balance being an organic solvent; B component comprises triethylenetetramine, a catalyst, an adhesion promoter, and absolute ethyl alcohol. The mass ratio of A component to B component is 20-25:1; and the thermal insulation material is a mixture prepared by mixing mica powder, alumina silicate fiber and aluminum oxide short fiber at a mass ratio of 10-12:8-10:5-20. The environment-friendly room temperature curing organic silicon high-temperature resistant coating is capable of solving the room temperature solidification problem of organic silicon high-temperature resistant thermal-insulating coatings, simplifying construction technologies, reducing construction energy consumption, and expanding the application range of organic silicon high-temperature resistant thermal-insulating coatings. Crosslink density of films made of the environment-friendly room temperature curing organic silicon high-temperature resistant coating is high, and fuel oil resistance is excellent. Aluminum oxide short fiber is used as the thermal insulation material, no coating additive is used, no priming paint is needed, the high-temperature resistance of the environment-friendly room temperature curing organic silicon high-temperature resistant coating is high, and the environment-friendly room temperature curing organic silicon high-temperature resistant coating is capable of resisting a temperature higher than 900 DEG C.
Description
technical field [0001] The invention relates to the technical field of coatings, in particular to an environment-friendly room-temperature-curing organic silicon high-temperature-resistant coating, and a preparation method thereof. Background technique [0002] Silicone resin and coating have good temperature resistance, weather resistance and corrosion resistance, and are currently very good temperature-resistant and heat-insulating protective materials. However, silicone resin and heat-resistant and heat-resistant coatings have the following disadvantages: 1) It needs to be heated and cured to form a film, which usually needs to be heated at 160-180°C for more than 4 hours to cure and form a film. It is very inconvenient, and accompanied by a large energy consumption, the application range is limited; 2) The heat-resistant and heat-insulating effect is not ideal; 3) The usual silicone resin and heat-resistant and heat-resistant coatings are all benzene as solvents, benze...
