いた。Conventionally, when manufacturing a patterned calcium silicate plate, a plate-shaped molded body made of a calcium silicate raw material is cured and cured in an autoclave or the like, and then the surface of the plate-shaped molded body is coated with various coating means, and then dried and baked. It depended on

ための熱処理を要するので工数及びコスト的な面で不利
となる問題が有った。Therefore, in conventional painting of calcium silicate plates, a separate painting process is required after the curing process, and heat treatment for drying and baking is required, which is disadvantageous in terms of man-hours and costs. .
さらに、塗装の乾燥、焼付が完了するまでは、板材を積
重した場合など塗料のブロッキングも生じやすく、管理
も面倒である問題が有った。Furthermore, until the drying and baking of the paint is completed, blocking of the paint is likely to occur, such as when board materials are stacked, and management is troublesome.
この発明は、上記問題点に鑑み、養生工程終了と共に、

てなされたものである。In view of the above-mentioned problems, this invention, upon completion of the curing process,
The purpose of this invention is to provide a method for temporarily producing patterned calcium silicate, which allows the production of patterned calcium silicate plates to be completed in one step, and which does not cause problems such as blocking.

である。(Technology for Solving Problems) That is, the method for manufacturing a patterned calcium silicate board of the present invention involves applying a high molecular weight emulsion paint to the surface of an uncured calcium silicate board with a water content of 35 to 60%, and then This method is characterized in that the uncured molded body is pressed and dehydrated, and then cured in an autoclave.

り珪酸カルシウム板表面に圧入浸透される。In this invention, when coating a paint on an uncured calcium silicate plate with a moisture content of 35 to 60% and compressing and dehydrating it using a press device, in addition to dehydrating the calcium silicate plate itself, the paint applied to the surface is also compressed and dehydrated. Moreover, since the emulsion paint has a large molecular weight, the compression pressure at this time causes it to be forced into the surface of the calcium silicate plate.

にエマルジョン塗料の含水率が非常に低くなるため、板
材を積重しても塗料のブロッキングは全く生じない。Further, after the dehydration process is completed, the water content of the emulsion paint together with the uncured calcium silicate temporary is extremely low, so even if the plates are stacked, no blocking of the paint will occur.

構成されている。The method for producing a patterned calcium silicate board of the present invention is to produce an uncured molded body 1 of a calcium silicate board with a moisture content of 35 to 60%, which is formed by a papermaking method, an extrusion method, a fourdrinier method, a casting method, or the like. An emulsion paint 2 made of a resin with a large molecular weight, for example, 10,000 to 50,000, which easily penetrates into the matrix of the calcium silicate plate, is applied to the surface by a spray method.
It is applied by a flow coater method or the like, and then the uncured molded body is press-compressed using a press device 3 to dehydrate it.
After that, curing is performed in an autoclave 4.
上記実施例においてプレス時に同時に凹凸模様を付する
ことも出来る。In the above embodiments, an uneven pattern can also be added at the same time as pressing.
また、塗料はプレス工程前に塗布するのでプレス金型に
付着しないよう顔料の比率を多くした塗料を使用する。Furthermore, since the paint is applied before the press process, a paint with a high pigment content is used to prevent it from adhering to the press mold.
なお、この場合、顔料の比率をあまり高くすると塗料の
金型への付着防止には良いが、珪酸カルシウム板への密
着性が低下するため、これらを勘案してＲ料と樹脂の割
合を重量比にして、５対１〜１５対１とすることが望ま
しい。In this case, if the pigment ratio is too high, it will be good for preventing the paint from adhering to the mold, but the adhesion to the calcium silicate plate will decrease. The ratio is preferably 5:1 to 15:1.

である。Since this invention is constructed as described above, when obtaining a colored calcium silicate board, baking of the paint and curing of the calcium silicate board can be performed at the same time, and the painting process after curing and curing can be completely omitted, which is remarkable. In addition to having the advantage of saving labor, it is also possible to add an uneven pattern during the pressing process, making it extremely easy to manufacture patterned decorative boards.
