この発明は建築用板材に関し、詳しくは防黴セメント建
築用板材に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a construction board, and more particularly to a mold-proof cement construction board.
従来、建築用板材としてセメン１〜を主戒分として或形
された無機質建材が非常に広く使用されている。BACKGROUND OF THE INVENTION Conventionally, inorganic building materials made of cement 1 or more have been widely used as building board materials.
これら無機質建月は通常抄造法、乾式法あるいば押出威
形などにより未硬化の板状物を或形し、その後自然養生

ープ養生を行なう事に依り製品化することが行われてい
る。These inorganic construction materials are usually formed into uncured plate-like materials using a paper-forming method, a dry method, or an extrusion method, followed by natural curing, painting with an organic paint, and then O-1-crepe curing. Depending on the situation, it is being commercialized.
しかし従来の無機質建材は、表面塗装が有機系塗料によ

失して板材表面が粗になると表面に黴が発生し美観を著
るしく損なう問題が有った。However, since the surface coating of conventional inorganic building materials is based on organic paint, deterioration over time can be avoided.If the surface coating disappears and the board surface becomes rough, mold will form on the surface and the aesthetic appearance will be significantly degraded. There was a problem with damage.
これを防止するため、有機系塗料中に防黴剤を添加する
場合もあるが、黴は塗装された表面塗膜が消失し、板材
表面が粗になると生じて来るから有機系塗料中に防黴剤
を混入する方法は抜本的解決策とはならない。To prevent this, anti-mold agents are sometimes added to organic paints, but mold occurs when the painted surface coating disappears and the surface of the board becomes rough. The method of mixing fungicide is not a fundamental solution.
又、オートクレープ養生時、戒形体は１８０℃前後の高
温で８〜１０時間曝されるため、市販の防黴剤では上記
養生中に分解、変質することがあり無効となる場合が多
いといった問題が有った。In addition, during autoclave curing, the mold-shaped bodies are exposed to high temperatures of around 180°C for 8 to 10 hours, so commercially available fungicides often decompose and change in quality during the curing process, making them ineffective. There was.
この発明は前記問題点に鑑め、セメントの板利戒形後の

である。In view of the above-mentioned problems, this invention is designed to solve the problem during autoclave curing after cement molding. 7171 The purpose is to provide architectural board materials that do not decompose or change in quality due to temperature or time, do not lose the surface coating layer, can prevent the generation of mold, and also maintain aesthetic appearance and do not impair the design appearance. It has been done.

るものである。That is, the architectural board of the present invention + No. A; I is coated with glass powder containing a metal oxide having antifungal properties against cement 3 and 4 on the surface of a plate-like body made of a cement composite. 1
0 part by weight is formed, and the cement composition contained in the coating layer and the metal oxide-containing glass having fatty mold properties are uniformly dispersed and bonded. That is.

面層となる七メン１・組或物に添加されるガラス粉末は
ホウゲイ酸ガラスなど水に依り徐々に溶解するものが使
用される。The glass powder added to the surface layer of the inorganic building material made of cement 8J1 of the present invention is one that gradually dissolves in water, such as borogate glass.

配合とずること乙こより防黴時問の調節を訓ることか出
来る。Examples of metal oxides having fungicidal properties added to the borosilicate glass include copper oxide or silver oxide, and these are added in an amount of 0.5 to 2.0 parts by weight based on the glass. I can learn about the formulation of II and the adjustment of anti-mold dosage from Zuko and Otsuko.

出し防黴効果か得られる。Copper ions and silver ions are effective in preventing mold from forming on Shichimen I-type board materials. When mixed and integrated, the metal oxides exist as ions in the molten borosilicate glass, and the glass gradually dissolves due to rain, etc., and metal ions such as Cu and Ag contained in it flow out, resulting in an anti-mildew effect. or can be obtained.

ス粉末の添加量を２〜１０重量部に限定した理由は、２
重量部以下では防黴効果が充分でなく、１０重量部以上
では七メン１・板祠の被覆層の耐衝撃強度が劣化するか
らである。The reason for limiting the amount of glass powder containing mold-killing metal oxides such as copper oxide or silver oxide to the cement composition in this invention is limited to 2 to 10 parts by weight.
This is because if the amount is less than 1 part by weight, the anti-mildew effect will not be sufficient, and if it is more than 10 parts by weight, the impact resistance strength of the coating layer of Shichimen 1/Itabako will deteriorate.
