本発明は模様付きセメント混和物板の製造方法に関し、
特に模様付き石綿セメント板の製造に有用なものである
。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a patterned cement mixture board;
It is particularly useful for producing patterned asbestos cement boards.
セメント混和物を使用した建築用板材として繊維補強材
を混合した板材があり、この繊維補強セメント板材とし
ては、石綿セメント板が汎用されている。As architectural board materials using cement mixtures, there are boards mixed with fiber reinforcement materials, and asbestos cement boards are commonly used as fiber-reinforced cement board materials.
この石綿セメント板は乾式法、或いは湿式法により石綿
セメント生原板を得、これを養生することにより得られ
る。This asbestos cement board is obtained by obtaining a raw asbestos cement board by a dry method or a wet method and curing it.
特に、石綿セメント板の表面を着色する場合は、石綿セ
メント生原板の一成形段階である圧縮段階の前段階で石
綿セメント生板の表面に着色粉末塗料を塗布しこの塗布
後に、上記の圧縮を行い、次いで、着色塗装表面に透明
のプラスチック塗膜を被覆し、而るのちに養生する方法
が用いられている。In particular, when coloring the surface of an asbestos-cement board, a colored powder paint is applied to the surface of the asbestos-cement raw board before the compression stage, which is a forming stage of the asbestos-cement raw board, and after this application, the above-mentioned compression is applied. A method is used in which the colored coating surface is coated with a transparent plastic coating film and then cured.
この方法において、透明のプラスチック塗膜を被覆する
理由の一つは、セメント養生時に、セメントの水利反応
により生成された水酸化カルシウムのうち、遊離状態に
ある水酸化カルシウムが着色塗装層の表面に析出するの
を防止するためである。One of the reasons for using a transparent plastic coating in this method is that during cement curing, free calcium hydroxide from the calcium hydroxide produced by the cement's water use reaction is transferred to the surface of the colored coating layer. This is to prevent precipitation.
すなわち、上記遊離状態の水酸化カルシウムはセメント
中に残存している遊離水に解かされるので、この遊離水
が着色塗装層の表面に滲出されると、水酸化カルシウム
が着色塗装層の表面に析出される。That is, the above-mentioned free calcium hydroxide is dissolved into free water remaining in the cement, so when this free water oozes out onto the surface of the colored paint layer, calcium hydroxide is dissolved onto the surface of the colored paint layer. It is precipitated.
このため上記したプラスチック塗膜によって上記遊離水
の着色塗装層表面への滲出を阻止している。Therefore, the above-described plastic coating film prevents the free water from seeping onto the surface of the colored coating layer.
しかしながら、このようにして得られる着色石綿セメン
ト板は単一色の単調な外観であり、外観的には必ずしも
満足なものとはいえ難い。However, the colored asbestos cement board obtained in this way has a monotonous appearance of a single color, and cannot necessarily be said to be satisfactory in terms of appearance.
