【発明の属する技術分野】
本発明は押出成形によって製造される木質セメント板に関するものである。
【0002】
【従来の技術】
従来、例えば外壁材等に使用される木質セメント板は、セメントと、パルプのような木質補強材とを主体とする原料混合物と水との混練物を平板形状に押出し成形し、得られた平板形状の成形体表面に振動プレスによって凹凸模様を成形する方法によって製造されていた(例えば特許文献1参照)。
【0003】
【特許文献1】
特開平5−329823号公報
【0004】
【発明が解決しようとする課題】
上記従来方法にあっては、振動プレスによって凹凸模様を成形する場合、凹凸差が大きいと成形量が大きくなり、シャープな凹凸模様が成形出来ない。また振動プレスによればプレス時に成形物内で材料が振動によって動くので凹部と凸部との比重差が少なくなる方向に好影響を与えるが、プレス型による凹凸差が大きいと比重差も大きくなって、振動だけでは比重差は改善されず、成形物全体の物性に悪影響がもたらされるようになる、と云う問題点があった。
【0005】
【課題を解決するための手段】
本発明は上記従来の課題を解決する手段として、セメントと木質補強材とを主体とする原料混合物と水との混練物を押出成形することによって前駆成形形状を有する予備成形物とし、該予備成形物を振動プレスを用いて仕上げ成形することによって製造された押出成形木質セメント板を提供するものである。
【0006】
【作用】
本発明では押出成形によって目標成形形状の前駆形状を成形しておくから、振動プレス成形の際、凹凸差が大きくても成形量は余り大きくならず、そのためにシャープな凹凸模様を成形することが出来、かつ凹部と凸部との比重差も大きくならず、成形物全体の物性を向上させることが出来る。
本発明を以下に詳細に説明する。
【0007】
【発明の実施の形態】
本発明に使用するセメントは、例えばポルトランドセメント、あるいはポルトランドセメントに高炉スラグを混合した高炉セメント、フライアッシュを混合したフライアッシュセメント、火山灰や白土等のシリカ物質を混合したシリカセメント、アルミナセメント、高炉スラグ等がある。
【0008】
本発明に使用する木質補強材は、例えば木粉、木毛、木片、木質繊維、木質パルプ、木質繊維束等があり、該木質補強材は二種以上混合されてもい。木質補強材として木質パルプや木粉のような微細なものを使用した木質セメント板廃材粉砕物を用いれば、混練物の押出成形性は木質補強材によって阻害されることなく良好に保たれる。
また更に本発明では竹繊維、竹チップ、麻繊維、ヤシ繊維、バカス、モミガラ、稲わら、サトウキビの搾り滓等の木材以外の木質補強材を使用することも出来る。
上記木質補強材の中では木質パルプ、木粉を使用することが好ましい。
【0009】
上記成分以外、本発明においては、例えばシリカ粉、ケイ砂、ケイ石の粉末、水ガラス、ケイ藻土、ドロマイト、シリカヒューム、高炉スラグ、フライアッシュ、シラスバルーン、パーライト等のケイ酸含有物質が添加されてもよく、 更に本発明では木質セメント板廃材粉砕物を使用することも出来る。また更に吸水性ポリマー、カルボキシメチルセルロース、メチルセルロース、メトキシセルロース、エトキシセルロース、アルギン酸塩、ポリアクリル酸塩等の水溶性高分子、プラスチック発泡体粉砕物、プラスチック発泡性ビーズの予備発泡体、プラスチック発泡性ビーズの完全発泡体、防水剤、撥水剤、顔料、染料等が添加されてもよい。
【0010】
一般に上記木質補強材は原料混合物中2〜10質量%、セメントとケイ酸含有物質との質量比は50:50〜70:30程度に設定される。また木質セメント板廃材粉砕物を使用する場合には原料混合物中0〜45質量%添加される。
【0011】
木質セメント板を軽量化するためにはプラスチック発泡体を添加することが望ましい。このようなプラスチック発泡体は、プラスチック発泡体、特にプラスチック発泡体廃棄物の粉砕物、プラスチック発泡性ビーズの予備発泡体、プラスチック発泡性ビーズの完全発泡体等として添加される。上記プラスチック発泡体としては、例えばポリスチレン発泡体、ポリエチレン発泡体、ポリプロピレン発泡体、フェノール樹脂発泡体、メラミン樹脂発泡体等がある。
【0012】
押出成形の際の成形性を向上させるために、水溶性高分子を添加して混練物の流動性を改良したり、吸水性ポリマーを添加して混練物の保水性を大きくしたりすることが好ましい。
【0013】
木質セメント板廃材粉砕物は木質補強材を含み、したがって該廃材粉砕物を使用すれば原料混合物中の木質補強材の添加量をその分減らすことが出来るし、またある程度の自己硬化性を有するので、ケイ酸含有物質と共に、あるいはケイ酸含有物質の一部に代えて使用すれば、得られる木質セメント板の強度を向上させることが出来る。
【0014】
上記原料混合物には水が添加され混練されるが、水の添加量は通常原料混合物100質量部に対して40〜70質量部とされる。
【0015】
上記混練物は押出機に充填され、該押出機のダイスから押出されるが、ダイス形状を所定の前駆成形形状として該前駆成形形状を有する予備成形物を成形する。押出圧力は通常0.5〜3MPaの範囲に設定する。該予備成形物は所定寸法に裁断され振動プレスされる。あるいは該押出成形では平板形状に押出し、押出機の後段に配置した型ロールまたはプレスによって予備成形物を成形してもよい。

【0018】
予備成形物PMは下定盤(2) 上にセットされ、上定盤(1) を介して振動盤(4) 、型板(5) を下降させ、該型板(5) に振動装置(3,3) によって振動を与えつゝ該予備成形物PMをプレス成形する。この場合の振動の周波数は一般的に30〜1000Hz、望ましくは50〜300Hz、振幅は1〜500μm、望ましくは50〜200μm、プレス圧は0.5〜3MPa、プレス時間は数秒とされる。上記振動プレスにおいては、予備成形物PMに全面的あるいは所定個所に離型剤を塗布しておいてもよい。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a wood cement board manufactured by extrusion.
[0002]
[Prior art]
Conventionally, for example, a wood cement board used for an outer wall material or the like is obtained by extruding a kneaded material of a raw material mixture mainly composed of cement and a wood reinforcing material such as pulp and water into a flat plate shape, and forming the obtained flat plate. It has been manufactured by a method of forming a concavo-convex pattern on the surface of a shaped body by a vibration press (for example, see Patent Document 1).
[0003]
[Patent Document 1]
JP-A-5-329823
[Problems to be solved by the invention]
In the above-mentioned conventional method, when forming a concavo-convex pattern by a vibration press, if the concavo-convex difference is large, the amount of molding becomes large, and a sharp concavo-convex pattern cannot be formed. In addition, according to the vibration press, the material moves by vibration in the molded product at the time of pressing, which has a positive effect on the direction in which the specific gravity difference between the concave portion and the convex portion is reduced. Thus, there is a problem that the difference in specific gravity is not improved by vibration alone, and the physical properties of the entire molded product are adversely affected.
[0005]
[Means for Solving the Problems]
As a means for solving the above-mentioned conventional problems, the present invention provides a preformed product having a preformed shape by extruding a kneaded product of a raw material mixture mainly composed of cement and wood reinforcing material and water, and forming the preformed product. An object of the present invention is to provide an extruded wood cement board manufactured by finish-molding an object using a vibration press.
[0006]
[Action]
In the present invention, since the precursor shape of the target molding shape is molded by extrusion molding, the amount of molding is not so large even when the difference in irregularities is large, and therefore, it is possible to mold a sharp irregular pattern during vibration press molding. As a result, the specific gravity difference between the concave portion and the convex portion does not increase, and the physical properties of the entire molded product can be improved.
The present invention will be described in detail below.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION

[0008]
The wood reinforcing material used in the present invention includes, for example, wood flour, wood wool, wood chips, wood fiber, wood pulp, wood fiber bundle, and the like. Two or more wood reinforcing materials may be mixed. If a pulverized wood cement board waste material using a fine material such as wood pulp or wood flour is used as the wood reinforcing material, the extrudability of the kneaded material can be kept well without being hindered by the wood reinforcing material.
Further, in the present invention, a wood reinforcing material other than wood, such as bamboo fiber, bamboo chip, hemp fiber, coconut fiber, bacas, fir, rice straw, and sugarcane scum can also be used.
Among the above wood reinforcing materials, it is preferable to use wood pulp and wood flour.
[0009]
Other than the above components, in the present invention, for example, silica-containing substances such as silica powder, silica sand, silica powder, water glass, diatomaceous earth, dolomite, silica fume, blast furnace slag, fly ash, shirasu balloon, pearlite, etc. It may be added, and in the present invention, a pulverized wood cement board waste material can also be used. Water-absorbing polymers, water-soluble polymers such as carboxymethylcellulose, methylcellulose, methoxycellulose, ethoxycellulose, alginate and polyacrylate, pulverized plastic foam, prefoamed plastic foam beads, and plastic foam beads May be added, a waterproofing agent, a water repellent, a pigment, a dye, and the like.
[0010]
Generally, the wood reinforcing material is set to 2 to 10% by mass in the raw material mixture, and the mass ratio of cement to the silicic acid-containing substance is set to about 50:50 to 70:30. When using a wood cement board waste material pulverized material, it is added in an amount of 0 to 45% by mass in the raw material mixture.
[0011]
In order to reduce the weight of the wood cement board, it is desirable to add a plastic foam. Such plastic foams are added as plastic foams, especially pulverized plastic foam waste, prefoamed plastic foamed beads, full foamed plastic foamed beads and the like. Examples of the plastic foam include polystyrene foam, polyethylene foam, polypropylene foam, phenol resin foam, and melamine resin foam.
[0012]
In order to improve the moldability during extrusion molding, it is possible to improve the fluidity of the kneaded material by adding a water-soluble polymer, or to increase the water retention of the kneaded material by adding a water-absorbing polymer. preferable.
[0013]
Since the crushed wood cement board waste material contains wood reinforcement, the use of the crushed waste wood material makes it possible to reduce the amount of wood reinforcement added to the raw material mixture, and has a certain degree of self-hardening. When used together with or in place of a part of the silicic acid-containing substance, the strength of the obtained wood cement board can be improved.
[0014]
Water is added to the raw material mixture and kneaded, and the amount of water added is usually 40 to 70 parts by mass with respect to 100 parts by mass of the raw material mixture.
[0015]
The kneaded product is filled in an extruder and extruded from a die of the extruder. A preform having the preformed shape is formed by setting the die shape to a predetermined preformed shape. The extrusion pressure is usually set in the range of 0.5 to 3 MPa. The preform is cut to a predetermined size and subjected to vibration pressing. Alternatively, in the extrusion molding, the preform may be extruded into a flat plate shape, and the preform may be molded by a mold roll or a press arranged at the subsequent stage of the extruder.
