Abstract
PURPOSE: To form an excellent coating layer having nonbrittleness and transparency, by a method wherein an alkali metal silicate is modified by a phosphate of a group 1a alkali metal of the periodic table and, thereafter, a silica coating layer is formed.
CONSTITUTION: A solution of a formula M2O.XSiO2.YH2O (M is a group 1a alkali metal of the periodic table, X is positive number of 0.5 or higher, Y is 0 or a positive number) is modified with a solution of a phosphate, a borate or the like of a group 1a alkali metal of the periodic table, such as sodium monohydrogen phosphate, to obtain an aqueous modified alkali metal silicate solution. In this case, the modifying agent is added in a total amount of 1W30mol to 10mol of SiO2 in terms of P2O5, B2O3, and Al2O3. When this aqueous modified alkali metal silicate solution is coated to a substrate surface and dried, a nonbrittle and transparent silicious coating layer with good performance is obtained.
