Problems solved by technology
[0004] However, in the above-mentioned technical scheme, there are problems such as complex manufacturing process, many components, high construction requirements, and inability to apply a single thick coating.
In addition, application numbers 201210539369.0 and 201210450763.7 respectively disclose a titanium-containing ceramic coating and a ceramic coating with a 3D effect, but the above two coatings need to be baked at high temperature to form a film and cannot be cured at room temperature
[0005] The production and preparation process of general ceramic coatings is cumbersome, with many components, high construction requirements, complex film-forming process, not suitable for the coating of large items, and the film thickness of one-time film formation is small, easy to crack, and cannot be cured at room temperature. Application fields of ceramic coatings

The invention discloses a nano ceramic coating capable of being cured at a normal temperature. The nano ceramic coating comprises a component A consisting of silicon sol, pigments, filler and water, and a component B consisting of siloxane, an aid, a drier and a solvent. The nano ceramic coating can be cured at the normal temperature, so that the application range is enlarged. In addition, the invention also discloses a preparation method of the nano ceramic coating capable of being cured at the normal temperature. The preparation method comprises the following steps: step 1, weighing the silicon sol, pigments, filler and water according to a corresponding ratio, mixing, stirring an obtained mixture, grinding the uniformly stirred mixture to powder with fineness of not higher than 25 micrometers, and adopting the powder as the component A; weighing the siloxane, aid, drier and solvent according to a corresponding ratio, mixing, uniformly stirring an obtained mixture, and adopting the mixture as the component B; and step 3, sufficiently mixing the component A and the component B according to a ratio, and generating the nano ceramic coating.
Description
technical field [0001] The invention relates to the technical field of nano-ceramic coatings, more specifically, the invention relates to a nano-ceramic coating curable at room temperature, and also relates to a preparation method of the nano-ceramic coating. Background technique [0002] At present, my country has entered a period of rapid development of high-tech products, but in the field of coatings, especially in the field of coatings with special functions, it still lags behind Western countries. Although nano-ceramic coatings have appeared in China for many years, there are also some joint ventures and private enterprises. Industrialization has been achieved, but the development is relatively slow. In addition to the gap between the technical strength and foreign companies, the current high price, poor mechanical properties, cumbersome construction technology and high curing conditions limit the application field of ceramic coatings, which is also the main reason.
