Problems solved by technology

[0016] In addition, as a coating using inorganic components, alkali silicate is a soluble silicate, a coating agent that has excellent adhesion and dispersibility due to alkali metals with strong hydrophilicity, but for fields that require water resistance , there are limitations in its application
[0017] Therefore, in order to improve the water resistance of the coating utilizing the inorganic components, the molar ratio of the silicate can be increased to prepare the coating composition, but the stability of the solution cannot be satisfied, and gelation will occur.
[0018] In addition, if alkoxysilane is added as a viscosity enhancer, the water resistance will be greatly improved, and it can be used in various forms, but there is a problem of low curability

[0038] According to another aspect of the present invention, there is provided a method for preparing an inorganic coating agent composition, comprising the following steps: the step of forming a modified silane silicate composition, based on 100 parts by weight of silicate, adding to the The silicate is added with 0.1 to 2 parts by weight of silane, diluted at a temperature range of 95 to 110 ° C, and stirred at a speed of 200 to 400 rpm for 1 to 2 hours; the silane compound formation step is based on 100 parts by weight of silane, mixing silane and After 0.01 to 3 parts by weight of a catalyst formed of hydrochloric acid, sulfuric acid or a mixture thereof, and 70 to 120 parts by weight of water, stirring at 200 to 400 rpm for 1 to 4 hours at a temperature range of 80 to 90 ° C, thereby forming a hydrolyzed silane compound ; In the temperature range of 65 to 110 ° C, based on 100 parts by weight of the modified silane silicate composition prepared according to the step of for...

Embodiment 1

[0095] First, 100 g of alkali silicate and 1 g of plastic trimethoxysilane were mixed, and stirred at a speed of 300 rpm for 1.5 hours at a temperature of 97° C. or higher to form a modified silane silicate composition.

[0096] Next, 100 g of epoxysilane, 1 g of hydrochloric acid, and 100 g of water were mixed, added to epoxysilane, and stirred at about 300 rpm for 3 hours at a temperature of 85° C. to form a hydrolyzed silane compound.

[0097] Next, while maintaining a temperature of 70°C, 100 g of the modified silane silicate compound, 20 g of a hydrolyzed silane compound, 150 g of a water-dispersible polyurethane dispersant, 15 g of acrylic emulsion resin, and 100 g of water were mixed to prepare an inorganic coating agent composition. .

Embodiment 2

[0099] First, 100 g of alkali silicate and 1 g of plastic trimethoxysilane were mixed, and stirred at a speed of 300 rpm for 1.5 hours at a temperature of 97° C. or higher to form a modified silane silicate composite.

[0100] Next, after mixing 1 g of hydrochloric acid and 100 g of water to 100 g of epoxy silane, it added and mixed with epoxy silane, and stirred at 300 rpm for 3 hours in the temperature range of 85 degreeC, and formed the hydrolysis silane compound.

[0101] Next, maintain a temperature of 70° C., mix 100 g of the modified silane silicate compound, 20 g of the hydrolyzed silane compound, 150 g of water-dispersible polyurethane dispersant, 15 g of acrylic emulsion resin, 20 g of surfactant composed of amine salt, and 100 g of water. Thus, an inorganic coating agent composition was prepared.
