The present invention attempts to suppress the occurrence of efflorescence by applying a paint containing aluminum dihydrogen tripolyphosphate to a coated object where efflorescence is likely to occur. Cement products, products using alkali metal silicates, etc. contain alkaline earth metal hydroxides, alkali metal hydroxides, etc. that may interact with carbon dioxide, sulfur oxides, etc. present in the air. Reacts to form white carbonate or sulfate crystals. This phenomenon is called efflorescence and stains the surface of the product in the form of white spots. Particularly when there is a large amount of water in the product, a large amount of alkaline earth metal or alkali metal hydroxide is transported to the product surface due to capillary action, so the formation of the above-mentioned efflorescence is said to be rapid. As a preventive measure against efflorescence, there is a method of adding stearate to cement (Japanese Patent Application Laid-open No. 57-1999).
Although various methods have been proposed, such as a method of applying a paint containing fluoride (Japanese Patent Application Laid-Open No. 149749/1983), none of them are satisfactory. The present inventors focused on the large alkali ion and alkaline earth ion adsorption ability of aluminum dihydrogen tripolyphosphate, and as a result of intensive research, the present invention was achieved. That is, the present invention applies a paint to which aluminum dihydrogen tripolyphosphate is added to an object to be coated where the efflorescence phenomenon may occur, and fixes alkali metal or alkaline earth metal ions with aluminum dihydrogen tripolyphosphate. In particular, it attempts to suppress the formation of efflorescence. The paints of the present invention can be applied to slate boards, hardened cement (hardened concrete),
Possible examples include cured alkali silicate salts. In addition, there are no particular restrictions on resins for coatings, but acrylic resins, vinyl acetate-acrylic copolymer resins, vinyl chloride-acrylic copolymer resins, urethane resins, epoxy resins, silicone resins, synthetic rubber resins, Relatively alkali-resistant resins such as silica sol and alumina sol are preferred. Aluminum dihydrogen tripolyphosphate
It is a substance represented by H 2 AlP 3 O 10 ·2H 2 O, and is usually produced by the method of Japanese Patent Publication No. 51-560, Japanese Patent Publication No. 55-050884, etc. The amount of aluminum dihydrogen tripolyphosphate added in the paint is usually 0.01 to 50%, preferably 0.1 to 50%.
It is 20%. If it is less than 0.01%, the desired effect of preventing efflorescence will not be achieved. Moreover, if it exceeds 50%, gelation of the paint tends to occur. It is also possible to use common extender pigments, coloring pigments, etc. in the paint of the present invention. Examples are shown below to explain the present invention in detail, but the present invention is not limited thereto. Example 1 Add aluminum dihydrogen tripolyphosphate (K manufactured by Teikoku Kako Co., Ltd.) to 100 parts by weight of epoxy resin paint (commercial product).
- 1 part by weight of bond #80) was added to obtain the coating material of the present invention. This paint was spray applied to an asbestos slate board and dried at 120°C for 10 minutes to create a coated board with a film thickness of 20μ. Example 2 A paint of the present invention was obtained by adding 2 parts by weight of aluminum dihydrogen tripolyphosphate (K-Bond #80 manufactured by Teikoku Kako Co., Ltd.) to 100 parts by weight of an acrylic emulsion paint (commercially available). This paint was spray applied to the slate board and allowed to air dry for one week to produce a coated board with a film thickness of 30 μm. Comparative Examples 1 and 2 Comparative Examples 1 (epoxy paint) and 2 (acrylic emulsion paint) were made of slate boards coated with the above-mentioned commercially available paints to the same thickness. The efflorescence test was conducted after 6 months of outdoor exposure and by immersing only the back side of the painted asbestos slate board in a saturated slaked lime aqueous solution for 30 days.
