Description

Ceramic coatings, preparation method thereof and coating method using the coatings {Ceramic coatings, method for Julia and method for soating using Julia}

The present invention relates to a ceramic coating agent, and more particularly, to a ceramic coating agent having improved water resistance, corrosion resistance, fouling resistance, and flame retardancy, a manufacturing method thereof, and a coating method using the coating agent.

Generally, in order to prevent corrosion or breakage of the concrete structure due to moisture, it is required to coat the surface of the concrete structure. This coating process is generally accomplished by applying a polymer resin to the surface of a concrete structure.

Conventional coating method of the surface of the concrete structure is a pre-treatment step of removing and planarizing contaminants on the surface of the structure, forming a primer layer by coating a primer on the pre-treated surface, and applying an epoxy coating on the primer layer It includes the steps.

In general, inorganic floors such as tiles or marble are installed on floors of bathrooms, public baths, saunas, swimming pools, and the like to improve aesthetics of designs. Such inorganic flooring materials are not only excellent in abrasion resistance, durability, and discoloration resistance, but also exhibit high gloss and high smooth surface characteristics, and thus their use is increasing significantly.

And since the said epoxy resin composition is excellent in the mechanical property, corrosion resistance, adhesiveness, etc. of the hardened | cured material obtained, it is widely used in each field, such as a coating material, an adhesive agent, a laminated board, and an electronic component use.

However, since such epoxy resins are mostly used in a composition diluted in an organic solvent, an environmental problem is recently raised, so that an aqueous solution is required.

In addition, although an epoxy resin emulsion prepared by high-speed stirring with a homo mixer using a surfactant as an aqueous epoxy resin is widely known, this has a problem in that physical properties such as water resistance and adhesiveness are degraded under the influence of a surfactant.
