Abstract

PROBLEM TO BE SOLVED: To provide the board material with antimicrobial properties such as antifungal or termite-proof properties by mixing a halophenolic compound into a board material at the time of manufacturing any of boards each consisting of Ca- containing gypsum or cement. SOLUTION: In this production, as the halophenolic compound for providing a board material with antimicrobial properties, a trihalophenolic compound, particularly an alkali metal salt of a trihalophenolic compound, or more specifically, sodium 4- bromo-2,5-dichlorophenolate is used. Such an antimicrobial board material produced by the production is used for manufacturing any of boards each of which consists of Ca-containing gypsum or cement and is used for building or construction, such as a gypsum, wood chip cement, asbestos-slate, wood wool cement, pulp cement, asbestos cement-pearlite, asbestos cement-calcium silicate or gypsum plaster board. The alkali metal salt of trihalophenolic compound is capable of forming a precipitate product which is incorporated into the board constituent material in a firmly deposited state on it and hardly dissolved out or released from the resulting board material, by the reaction of the alkali salt with Ca ions in the board constituent material at the time of mixing the metal salt into a constituent material of any of the boards.

It is becoming more and more common to see the northern side of the intruded wall, the walls around the water in the washroom, and the ceiling becoming sticky and humid, and water droplets flowing in a string form. The terrible spots are often mistaken for rainwater infiltration, but this is not due to flaws in the flashing,
This phenomenon is caused by dew condensation, especially in poorly ventilated areas such as the inner wall facing the north side, the inner wall of the closet on the north side, the attic, etc. Bacteria are generated and cause damage such as damage by termites. In recent years, due to changes in building materials and construction methods, the hermeticity of buildings has become increasingly higher than before, and heating and heating appliances have also become more widespread. The damage is likely to increase further. There are two types of condensation: surface condensation and internal condensation.Surface condensation is a condensation phenomenon on the surface of a board or the like.For example, when the internal temperature of the board is lower than the dew point, This is a phenomenon in which dew condensation occurs on the surface, but dew condensation occurs on a low-temperature portion inside the surface.

When kneading fiber substances such as sawdust and water with water,
An antimicrobial agent comprising an aqueous solution of a phenol halide is kneaded into these materials. In particular, an alkali metal salt of a phenolic trihalide, particularly, sodium 4-bromo-2,5-dichlorophenol, is preferably kneaded. Thereby, by the reaction between the 4-bromo-2,5-dichlorophenol sodium and the Ca ions in the material constituting the plate material, a product that is embedded in the concrete and is difficult to be easily separated can be generated. It is possible to provide the boards with high antibacterial effect and long-lasting antibacterial property by the kneading.

Since the sublimation of BDCP is expected to decrease, air-dry weight measurement was performed. The BDCP-Na salt does not form a precipitate in the clear solution, but a large amount of precipitate is formed in the presence of the Ca salt. This is presumed to have the reaction of the above formula 2. The results are as follows. In the case of Ca (OH) 2 mixed solution In the case of CaO mixed solution Weight of Ca salt 3.30 g 2.50 g Weight of BDCP 11.82 g 11.82 g Solid weight 15.12 g 14.32 g Sediment weight 11.2951 g 12. 0060 g BDCP-Ca amount 12.5892% 12.5892% Ca chloride% 91.86% 95.37% Assuming that all Na salts of BDCP have been replaced by Ca salts, the precipitates are as follows. In the case of the Ca (OH) mixed solution, 91.86% In the case of the CaO mixed solution, 95.37% of the Na salt is larger than the Ca salt even if insoluble components of Ca (OH) and CaO are present. It is assumed that the part has been replaced.
