Problems solved by technology

[0003] However, in the methods (1) to (6) above, there are problems as follows: In the method (1), since cracks and peeling will occur when the film thickness is more than 0.1 μm, the film-forming property is poor, and it needs to be heated at several hundreds of degrees. Carry out sintering under the temperature above; (2) method, thermal decomposition product has bad influence to base material, needs to carry out sintering under the temperature of hundreds of degrees above; (3) method can not form compact film, and the adhesion to base material The method of (4) and (5) must be under reduced pressure to obtain a good film, and a reaction vessel that can be vacuumed is required. In addition, the film forming speed is generally slow. In order to obtain a dense film, the substrate needs to be heated to hundreds of degrees. Above; (6) method, the sol used is added with acid or alkali or organic matter, there is a problem of corrosion of the coated material, and in order to remove the organic matter, it needs to be operated above 400 ° C
[0005] But, the shortcoming of these two kinds of methods is: the method of (7) takes a long time to form film, and the processing of fluoride is troublesome; Pure membrane, it is difficult to control the pH and its variation will lead to different membranes, etc.
In order to add the above-mentioned titanium-based coating solution in a stable state, zirconium halides such as zirconium fluoride are generally used (Japanese Patent Application Laid-Open No. 2002-60975), but due to the presence of toxic substances such as hydrogen fluoride, its use is restricted by the application. limit

manufacture example 1

[0150] Adjust the pH of 100 parts of 35% hydrogen peroxide to 8.4 with ammonia water, and cool to 10° C. in an ice bath. Here, 1.4 parts of tetraisopropoxytitanium and 1.63 parts of tetra-n-propoxyzirconium were added dropwise over 1 hour while stirring. Filter the obtained orange-red transparent liquid, add 0.5 parts of 10% ammonia water and stir well, add deionized water to prepare a titanium-zirconium-containing aqueous solution P1 with a metal oxide concentration of 1%.

manufacture example 2

[0152] In 2000 parts of deionized water, 13 parts of titanium tetraisopropoxide and 20 parts of zirconium tetra-n-propoxide were added dropwise while stirring to carry out hydrolysis. The deposited precipitate was filtered and washed with water to obtain a titanium-zirconium hydrolyzate. Add 20 parts of 25% ammonia water to 100 parts of 35% hydrogen peroxide, and cool to 10° C. in an ice bath. There, the titanium-zirconium hydrolyzate was added over 30 minutes. After further reacting for 30 minutes, 50 parts of 60% 1-hydroxyethane-1,1-diphosphonic acid were added, followed by further stirring for 30 minutes. The obtained orange-red transparent liquid was filtered, and deionized water was added to prepare a titanium-zirconium-containing aqueous solution P2 with a metal oxide concentration of 5%.

manufacture example 3

[0154] Adjust the pH of 100 parts of 35% hydrogen peroxide to 8.4 with ammonia water, and cool to 10° C. in an ice bath. Here, 1.4 parts of tetraisopropoxytitanium and 1.63 parts of tetra-n-propoxyzirconium were added dropwise over 1 hour while stirring. After further reacting for 2 hours, 3.0 parts of ammonium glycolate was added, followed by further stirring for 30 minutes. The obtained orange-red transparent liquid was filtered, and deionized water was added to prepare a titanium-zirconium-containing aqueous solution P3 with a metal oxide concentration of 1%.
