問題があつた。[Background technology] Traditionally, gypsum board has been used as a single ceiling material and wall material, but indoor moisture can penetrate through the gypsum board into the ceiling, behind walls, etc., causing dew condensation. Ta. For this reason, a moisture-proof coating film is formed on the base paper for board on one or both sides of the gypsum board to provide moisture resistance, but when a moisture-proof resin paint such as vinylidene chloride resin is applied to the base paper for board, the paint There was a problem in that it impregnated into the board base paper, making it impossible to form a uniform and thin moisture-proof coating film, and making it impossible to provide stable moisture permeability and water permeability.

A moisture-proof coating film 3 is formed on the surface, and with this structure, the above object can be achieved. That is, since the moisture-proof coating film 3 is formed on the base paper 2 for boards with a Steckigt size degree of 320 or more, not only can the moisture-proof property be ensured, but also the moisture-proof resin paint can be impregnated into the base paper 2 for boards. Therefore, a uniform and thin moisture-proof coating film 3 can be formed.

もよい。 The present invention will be described below based on embodiments shown in the accompanying drawings. The gypsum board 1 is made by adding an appropriate amount of water to gypsum, an admixture material, etc., and kneading the mixture thoroughly as a core, and covering both sides and sides with a base paper 2 for board. This board base paper 2 has a Steckicht size degree indicating water resistance of 320 or more (according to JIS P8122) and a water absorption of 15 g/m 2 /40 g/m 2 or less (JIS P8140). In this embodiment, a moisture-proof resin paint made of vinylidene chloride resin is applied to one side of a gypsum board 1 to form a moisture-proof coating film 3. Moisture-proof resin paint is applied uniformly with a curtain flow coater in an amount of 65 to 100 g/ m2 , and dried in a hot air drying oven with a drying temperature set at 140℃ or higher and a drying time of 15 minutes or longer. do. In this case, since the Steckigt size degree of the base paper for board 2 is 320 degrees or more, the moisture-proof resin paint does not impregnate the base paper for board 2, and the moisture-proof coating film 3 can be formed with a small amount of coating and a small number of coatings. In this embodiment, the other surface of the gypsum board 2 is coated with a fungicide. The moisture permeability and water permeability of the moisture-proof gypsum board A constructed in this way is 60g/2, which is the quality standard for moisture-proof gypsum boards.
m2・24hr, 40mg/ cm3・7 days or less, and by using the surface with the moisture-proof coating film 4 as a ceiling material or wall material, indoor moisture will not infiltrate into the attic etc. For comparison, moisture-proof gypsum boards were manufactured in the same manner using board base papers with various Steckigt size degrees, and the relationship between the Steckigt size degree of the board base paper and moisture permeability was investigated. It is shown in Figure 2. As a result, if the Steckicht size degree is 320 or higher, it is a quality standard.
It turns out that it is 60g/m 2・24hr. In the case of this invention, base paper 2 for board with a Steckigt size degree of 320 or more is applied to both sides or the entire surface of the gypsum board 1.
may be coated with a moisture-proof coating film 3.
