Claims3
A method of preparing the inorganic film-forming coating composition, said method comprising adding a titanium monomer and/or a low condensation product thereof containing a group hydrolyzed to form hydroxyl group into a mixture of hydrogen peroxide water with water in such an amount that the titanium monomer and/or the low condensation product thereof may be hydrolyzed, followed by reacting to form a hydroxyl group-containing titanium compound and immediately followed by coordinating the hydroxyl group-containing titanium compound with hydrogen peroxide to form a chelate solution, and obtaining an inorganic film-forming coating composition comprising the chelate solution, the titanium monomer containing the group hydrolyzed to form hydroxyl group being represented by formula Ti(OR)4, wherein R is same or different, and represents an alkyl group having 1 to 5 carbon atoms, the low condensation product having a degree of condensation of 2 to 30, a mixing ratio of the titanium monomer and/or the low condensation product thereof containing the group hydrolyzed to form hydroxyl group to the hydrogen peroxide water being such that the hydrogen peroxide water is in the range of 0.1 to 100 parts by weight as hydrogen peroxide per 10 parts by weight of the titanium monomer and/or the low condensation product thereof, the reaction temperature being in the range of 100 to 70° C.
A method of forming an inorganic film, said method comprising coating an inorganic film-forming coating composition onto a substrate or impregnating the substrate with the coating composition, followed by drying or heat treating to form an inorganic film, the inorganic film-forming coating composition being prepared by a preparation method, said preparation method comprising adding titanium monomer and/or a low condensation product thereof containing a group hydrolyzed to form hydroxyl group into a mixture of a hydrogen peroxide water with water in such an amount that the titanium monomer and/or the low condensation product thereof may be hydrolyzed, followed by reacting to form a hydroxyl group-containing titanium compound and immediately followed by coordinating the hydroxyl group-containing titanium compound with hydrogen peroxide to form a chelate solution, and obtaining an inorganic film-forming coating composition comprising the chelate solution, the titanium monomer containing the group hydrolyzed to form hydroxyl group being represented by formula Ti(OR)4, wherein R is same or different, and represents an alkyl group having 1 to 5 carbon atoms, the low condensation product having a degree of condensation of 2 to 30, a mixture ration of the titanium monomer and/or the low condensation product thereof containing the group hydrolyzed to form hydroxyl group to the hydrogen peroxide water being such that the hydrogen peroxide water is in the range of 0.1 to 100 parts by weight as hydrogen peroxide per 10 parts by weight of the titanium monomer and/or the low condensation product thereof, the reaction temperature being in the range of 10° to 70° C.
An inorganic film prepared according to a method, said method comprising coating an inorganic film-forming coating composition onto a substrate or impregnating the substrate with the coating composition, followed by drying or heat treating to form an inorganic film, the inorganic film-forming coating composition being prepared by a preparation method, said preparation method comprising adding titanium monomer and/or a low condensation product thereof containing the group hydrolyzed to form hydroxyl group into a mixture of a hydrogen peroxide water with water in such an amount that the titanium monomer and/or the low condensation product thereof may be hydrolyzed, followed by reacting to form a hydroxyl group-containing titanium compound and immediately followed by coordinating the hydroxyl group-containing titanium compound with hydrogen peroxide to form a chelate solution, and obtaining an inorganic film-forming coating composition comprising the chelate solution, the titanium monomer containing the group hydrolyzed to form hydroxyl group being represented by formula Ti(OR)4, wherein R is same or different, and represents an alkyl group having 1 to 5 carbon atoms, and showing photoactivity, antibacterial properties, hydrophilic properties, pollution resistance, hazeproofness, gas decomposition properties, deodorizing properties, water treatment properties, energy transformation properties, decoloring properties and corrosion resistance.
