から構成されたものを言う。2. Description of the Related Art A flow-on molding method is known as a method for producing a fiber-reinforced cement board. This flow-on molding method is a kind of papermaking method in a method of producing a fiber-reinforced cement board, in which a cement slurry composed of a fiber-reinforced cement is supplied in a layer form on a felt belt equipped with a suction dewatering device, and a predetermined moisture content is obtained. It is transported and dehydrated until it becomes a plate shape, and then cut at predetermined lengths at the end of the felt belt,
It refers to a process consisting of a step of pressing to form an uneven pattern on the surface and curing and curing.

利点を有する。[0003] This fiber-reinforced cement board is manufactured by another papermaking method, for example, laminating a thin seed film made by a cylindrical round mesh on a making drum, and then cutting and flattening and pressing. This method has the advantage that a thick fiber reinforced cement board can be formed at a time and the production efficiency is good as compared with the round net forming method of forming a plate.

ることが行われ、この凹凸模様は既述のようにプレスに
より付されるが、上記抄造法により製造した繊維補強セ
メント板の場合、深い凹凸模様を鮮明に付すのが比較的
困難である問題があった。By the way, many fiber-reinforced cement boards are provided with an uneven pattern on the surface to impart a design, and the uneven pattern is formed by pressing as described above. However, in the case of the fiber reinforced cement board manufactured by the above-mentioned papermaking method, there is a problem that it is relatively difficult to give a deep uneven pattern clearly.
【０００５】即ち、抄造法で製板した場合、吸引脱水に

初期段階では金型凸部１の進入に伴い、凸部側面１Ａの
板材成形材料２が矢印で示すように進入方向に引き込ま
れ凸部周縁にクラック３が発生する。That is, when the sheet is made by the papermaking method, the moisture content of the sheet is considerably reduced by suction dehydration. When such a sheet is pressed, as shown in FIG. Along with the entry of the mold projection 1, the plate material 2 on the projection side surface 1A is drawn in the entry direction as shown by the arrow, and cracks 3 occur on the periphery of the projection.

が少ないとその流動性にも限界があるため完全には消滅
せず、結局初期段階にできたクラック３は程度は軽くな
るが、そのまま製品表面に残ってしまう問題があった。In the final stage of press compression, as shown in FIG. 6, the molding material 2 flows along the press platen surface 1B in the direction of eliminating cracks as indicated by arrows. However, there is a problem that the crack 3 formed in the initial stage is lightened to a small extent, but remains on the surface of the product as it is.

含有水分を高めて流動性を持たせ、この成形板材表面に
直接凹凸プレスすることにより深彫りの凹凸模様を付す
ことが通常行われていた。[0007] Therefore, in the case of the flow-on method, the suction dewatering amount is adjusted in the process of transferring the slurry poured onto the felt belt, and the water content is increased to a level at which the slurry can be manufactured to have fluidity. It has been customary to form a deeply carved uneven pattern by directly pressing the surface of the formed plate material.

のため製品表面のクラックや表面の粗面化による意匠性
の低下などを起こす問題があった。However, when the content of water is large, there is a problem that the shaping angle of deep carving is limited due to the fluidity remaining in the slurry after pressing. further,
If the water content is high, depending on the pressing pressure, water running occurs in the structure and surface of the uncured cement plate at the time of pressurization, and the outflow of inorganic particles contained in the structure occurs with the water running, Therefore, there has been a problem that cracks on the product surface and a decrease in design due to surface roughening are caused.

ト配合材料を層状に散布し、この上からプレスすること
によって深彫りの凹凸模様を成形することが提案されて
いる（例えば特公平5-11004号、同6-84006号等）。However, in order to solve such a problem, it is easy to adjust the water content of the sheet material by the flow-on method to 50%.
It has been proposed that a relatively dry powdery cement-mixed material be sprayed on the surface of the plate material in a layered form, and then pressed from above to form a deeply carved uneven pattern (for example, Japanese Patent Publication No. Hei 5- 11004 and 6-84006).

ばならならない。According to this method, the water content of the lower layer is absorbed into the surface layer at the time of pressing, so that the water content of the entire plate material is reduced and uniformized, and at the same time, a deeply carved uneven pattern can be formed by pressing the porous surface layer. Has advantages. However, during high-pressure pressing, the water in the lower layer must be transferred to the surface layer within a short period of time. For this purpose, a special cement compound for the surface layer must be used to improve the water absorption of the surface layer material.

The purpose of the present invention is to easily produce a deeply carved uneven pattern on the surface of a fiber-reinforced cement board manufactured by papermaking.

を特徴とするものである。According to a first aspect of the present invention, there is provided a method of patterning a fiber-reinforced cement board, comprising: supplying a layer of cement slurry onto a felt belt provided with a suction dewatering device; In the on-molding method, a cement slurry composed of a normal compound is supplied in a layered form on the felt belt, and in the process of being conveyed by suction dehydration, the cement slurry mixed with particles having a high aspect ratio particle shape is mixed with the layer. After laminating further as a base layer,
It is cut into dimensions suitable for press molding described below, and the cut uncured fiber-reinforced cement board is pressed from the upper layer to give an uneven pattern on the upper layer surface, and then cured and cured according to a conventional method. It is.

ーの流動性が良くなる性質を利用するためである。That is, the strength of the plate material is exerted by the base layer, and the surface layer is a layer which is formed so as to easily give an uneven pattern. The reason for adding the particles having a high aspect ratio to the surface layer is to utilize the property that the fluidity of the slurry in the flat direction is improved by the flat particle shape.

容易に付すことが可能となる。Since the particles added to the surface layer are oriented in various directions, the fluidity of the slurry can be considerably improved even if the water content of the slurry is not so high. Therefore, it is possible to easily apply even a concave / convex pattern having a large shaping angle and a deep carving.

The present invention is characterized in that a clay mineral having a thickening effect is added to a cement slurry mixed with particles having a particle shape having a high aspect ratio.

That is, the clay particles have a water retention property, and the hydrated clay particles exhibit thixotropic properties. As a result, even if the cement slurry contains a small amount of water, the fluidity is improved, and the reproducibility of the concavo-convex pattern by pressing is improved in cooperation with the particles having a high aspect ratio of the first aspect.
