【発明の詳細な説明】
近年、ALC材は建材として広く用いられるよ
うになつてきたが、本来、ALC材は吸水性が大
きくこのままでは建材としては不向きで、通常建
設時に表面塗装材を施している。[Detailed description of the invention] In recent years, ALC materials have come to be widely used as building materials, but ALC materials originally have high water absorption properties and are unsuitable as building materials as they are, so they are usually coated with a surface coating material during construction. There is.
建設時の表面塗装材施工によつて、表層部に高
分子物質の含浸層を有し、その表面に高分子物質
とフイラーよりなる塗装材を塗布したALC材は
既にある。 There are already ALC materials that have a polymer impregnated layer on the surface layer by applying a surface coating material during construction, and a coating material consisting of a polymer material and filler is applied to the surface.
この場合、含浸層と表面層の高分子物質は別個
に塗布乾燥されるので、両界面で不連続層となり
付着性の観点から好ましくない。 In this case, since the polymeric substances of the impregnated layer and the surface layer are applied and dried separately, a discontinuous layer forms at both interfaces, which is undesirable from the viewpoint of adhesion.
更に含浸層を欠く通常の技術においては、表面
層とALC表面の付着が良好に行われても、ALC
自体の引張強度が低いために付着層のすぐ下の
ALC部内で破壊が起り強い接着は得られない。 Furthermore, in conventional techniques lacking an impregnated layer, even if the surface layer and the ALC surface adhere well, the ALC
Due to its own low tensile strength, the
Destruction occurs within the ALC area and strong adhesion cannot be obtained.
また通常表面層のフイラーが無機質粉末である
ため、ALCとは異質な緻密層となり透湿性を失
い建材として好ましくない。更に別個にフイラー
を用意しなくてはならず割高であつた。 Furthermore, since the filler in the surface layer is usually an inorganic powder, it becomes a dense layer that is different from ALC and loses moisture permeability, making it undesirable as a building material. Furthermore, a filler had to be prepared separately, which was expensive.
一方、表面処理の施されていないALC材は表
面まで気泡が露出し、吸水性大で外観も粗く好ま
しくない。 On the other hand, ALC materials that have not been surface-treated have air bubbles exposed to the surface, are highly water-absorbent, and have a rough appearance, which is undesirable.
また、ALC材の表面塗装材施工に到るまで
に、ALC材に雨水の侵入などが起りその乾燥の
ため余分の工期を要していた。このためALC材
の製造場において完成ALC材の表面に防水性の
塗布剤を塗布、乾燥することが行われてもいる
が、この工程はすべて余分に追加されねばなら
ず、特に乾燥には大きな設備または広い場所を必
要とし不経済である。 Additionally, before the surface coating of the ALC material could be applied, rainwater had entered the ALC material, which required extra construction time to dry. For this reason, a waterproof coating agent is applied to the surface of the finished ALC material and dried at the ALC material manufacturing plant, but this process requires additional steps and takes a long time to dry. It is uneconomical as it requires equipment or a large space.
また塗布効果を上げるため塗布材に無機質フイ
ラーを入れるが、このための塗布材混合調整工程
が必要である。 Furthermore, an inorganic filler is added to the coating material in order to improve the coating effect, but a coating material mixing and adjustment process is required for this purpose.
本発明は上記諸欠点をすべて克服するものであ
つて、ALC材の製造工程内で表層部に防水加工
を施すため、以後の段階での水の侵入を防ぎ工期
の延長を防止できるだけでなく、処理後オートク
レーブ養生するので乾燥等の余分の後工程が不要
で設備は最小限ですむ。 The present invention overcomes all of the above-mentioned drawbacks, and since waterproofing is applied to the surface layer during the manufacturing process of ALC materials, it not only prevents water from entering in subsequent stages and prevents the extension of the construction period. Since it is cured in an autoclave after treatment, extra post-processes such as drying are not required, and the equipment required is minimal.
以上の処理によつてできた製品は表層部に含浸
層があるので付着性が極めてよい。即ちALCに
含浸した高分子物質がALC材を補強するので表
面層の剥離抵抗は非常に大きくなる。 The product produced by the above treatment has an impregnated layer on the surface and has extremely good adhesion. That is, since the polymer substance impregnated into ALC reinforces the ALC material, the peeling resistance of the surface layer becomes extremely high.
また、含浸層と表面層のそれぞれの結合材であ
る高分子物質は同一物質であり、且つ同時に乾燥
硬化されるので、両者は一体に成形され付着性が
よい。 Furthermore, since the polymeric substances that serve as the binders for the impregnated layer and the surface layer are the same and are dried and hardened at the same time, the two are integrally molded and have good adhesion.

更に表面層のフイラーがALC破砕物であるた
め、透湿性、外観などがALC材と同傾向とな
り、材質の均質性が保たれるだけでなく、別個の
フイラーが不要であり経済的である。〓〓〓〓〓
Furthermore, since the filler in the surface layer is crushed ALC material, its moisture permeability and appearance tend to be the same as those of ALC materials, which not only maintains the homogeneity of the material, but also eliminates the need for a separate filler, making it economical.
上記表面処理により防水性が極めて高くなり、
外観も緻密となり好ましくなる。 The above surface treatment makes the waterproof property extremely high.
The appearance also becomes denser and more desirable.

所定の条件で養生し表面改質ALC材を得る。 First, the ALC raw material slurry is poured into a mold, precured and foamed, and then cut into a predetermined shape or coated with a polymer solution or emulsion on the desired surface area without cutting by an appropriate method. The surface layer impregnated with the molecular solution or emulsion is mechanically crushed into small pieces. The coating method is not particularly limited, but the strips are mixed with a solution or emulsion and laminated onto the surface of the ALC material by brushing, spraying, or any other suitable method. If necessary, this surface is smoothed by pressing or stroking, and then cured in an autoclave under predetermined conditions to obtain a surface-modified ALC material.
