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: a step of forming a modified silane silicate composition, based on 100 parts by weight of silicate, to the Add 0.1 to 2 parts by weight of silane to the silicate, dilute at a temperature range of 95 to 110 ° C, and stir at a speed of 200 to 400 rpm for 1 to 2 hours; in the step of forming a silane compound, based on 100 parts by weight of silane, mix 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, the hydrolyzed silane compound is formed by stirring at 200 to 400 rpm for 1 to 4 hours at a temperature of 80 to 90° C. ; Under the temperature range of 65 to 110° C., based on 100 parts by weight of the modified silane silicate composition prepared according to the modified silane silicate compositio...

Embodiment 1

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

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

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

Embodiment 2

[0099] First, after mixing 100 g of alkali silicate and 1 g of plastic trimethoxysilane, the modified silane silicate composition was formed by stirring at a temperature of 97° C. or higher at a speed of 300 rpm for 1.5 hours.

[0100] Next, 1 g of hydrochloric acid and 100 g of water were mixed with 100 g of epoxysilane, and then added to and mixed with epoxysilane, and stirred at 300 rpm for 3 hours at a temperature of 85° C. to form a hydrolyzed silane compound.

[0101] Next, while maintaining the temperature of 70°C, 100 g of the modified silane silicate composition, 20 g of the hydrolyzed silane compound, 150 g of a water-dispersed polyurethane dispersant, 15 g of an acrylic emulsion resin, 20 g of a surfactant composed of an amine salt, and 100 g of water were mixed.
