沸点以下の温度で熱処理する。When the alkali metal silicate is only sodium silicate and / or potassium silicate, the water resistance and moisture resistance are not good and the use is limited. Also,
Lithium silicate alone has good water resistance and moisture resistance, but poor adhesion. The molar ratio of the total amount of sodium and potassium to lithium (the value of m in Chemical formula 1) is 0.1 to 3, preferably 0.2 to 2. When the value of m is less than 0.1, the water resistance and moisture resistance are poor, and when it exceeds 3, cracks are likely to occur in the coating. As for the value of m, a necessary amount of lithium silicate is mixed with an aqueous solution of sodium silicate and / or potassium silicate, and if necessary, heat treatment is performed at a temperature equal to or lower than the boiling point of water.

が悪くなる。The molar ratio of alkali metal to silicon (the value of n in Chemical formula 1) is 4 to 10, preferably 5 to 8. When the value of n is less than 4, the water resistance of the formed coating film decreases, and when it exceeds 10, the adhesiveness decreases. As a method of increasing the value of n, it is advisable to previously mix sodium silicate or potassium silicate with silica sol or fine particles of silicon oxide and heat and dissolve them. The mixing ratio of the alkali metal silicate aqueous solution and the alkali water-soluble silicone is 100 parts by weight of the solid content in the alkali metal silicate aqueous solution.
Solid content of alkali water-soluble silicone 3 to 100 parts by weight,
It is preferably 5 to 70 parts by weight. If the amount of the alkali-water-soluble silicone is less than this, cracks are likely to occur when the film thickness is 5 μm or more, and if it is too large, the moisture resistance of the coating film deteriorates.

る。Further, it is preferable to dissolve at least one selected from boric acid, zinc ions and aluminum ions in an aqueous solution of alkali metal silicate. Thereby, especially when the amount of silicon is small (n in the chemical formula 1
(When the value is small), the water resistance at the time of forming a film by baking is improved. The method of dissolving boric acid, zinc ions, and aluminum ions includes boric acid, borax, alkali metal salts of boric acid such as potassium borate and zinc and aluminum oxides, hydroxides, silicates, and silicofluorides. It is previously dissolved in an alkali metal silicate aqueous solution, and an alkali water-soluble silicone is mixed therein. The amount of boric acid, zinc ions, and aluminum ions added is 0.3 to 5% by weight, preferably 0.
The amount is 5 to 3% by weight. If it is less than 0.3%, the effect of addition is not obtained, and if it exceeds 5%, it is not completely dissolved. Residues that are not completely dissolved are usually removed by filtration.
