Description
【発明の詳細な説明】 〔産業上の利用分野〕 この発明は建築用無機質板材の化粧方法に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a method for decorating inorganic board materials for construction.
従来、セメントあるいは、石こうなどの水硬性原料によ
り成形した建築用無機質板材は、耐水性を付与し、ある
いは装飾を行うため、表面に水性エマルジョン塗料を塗
布したり、あるいは着色セメントによる化粧層を設けた
りすることが行なわれる。Conventionally, inorganic boards for construction made of hydraulic materials such as cement or plaster are coated with a water-based emulsion paint or a decorative layer of colored cement is applied to the surface in order to provide water resistance or decoration. There are many things that can be done.
しかし、上記着色層を設ける手段は、セメント等が硬化
する際に析出するエフロレッセンス等により剥離が生じ
やすくなり、また、着色セメント層の場合は耐水性が充
分とならない問題が有った。However, the method of providing the colored layer has the problem that peeling is likely to occur due to efflorescence etc. that precipitates when the cement etc. hardens, and that the colored cement layer does not have sufficient water resistance.
さらに、塗料による化粧方法の場合オートクレーブによ
る高温高圧養生の際、熱によりプロフキングが生じやす
く、不良品を発生させる問題も育った。Furthermore, in the case of cosmetic methods using paints, buffing tends to occur due to heat during high temperature and high pressure curing in an autoclave, leading to the problem of defective products.
この発明は上記問題点に鑑み、優れた密着強度となし得
また、耐水性も良好な化粧層を成形し得る建築用無機質
板材の化粧方法を得ることを目的としてなされたもので
ある。In view of the above-mentioned problems, the present invention has been made with the object of providing a decorative method for architectural inorganic board materials that can form a decorative layer with excellent adhesion strength and good water resistance.
即ち、この発明の建築用無機質板材の化粧方法はオート
クレーブ養生時の熱により溶融する熱可塑性フィルムと
溶融しないフィルムとから成る積層フィルムを養生前の
建築用熱ａ質板材表面に、熱溶融する面を接して敷設し
、しかる後前記板材をオートクレーブにより高温高圧蒸
気養生することを特徴とするものである。That is, the decorative method for architectural inorganic board materials of the present invention is to apply a laminated film consisting of a thermoplastic film that melts due to heat during autoclave curing and a film that does not melt onto the surface of the architectural alumina board material before curing. The plate material is laid in contact with each other, and then the plate material is cured with high temperature and high pressure steam in an autoclave.
この発明において、オートクレーブ養生時の熱により溶
融する熱可塑性フィルムとは、オートクレーブによる高
温高圧蒸気養生時の熱、具体的には１００℃〜１８０℃
前後の熱により溶融する熱可塑性合成樹脂フィルムを言
い、また溶融しない樹脂とは、上記温度範囲以上の溶融
点を有した熱可塑性合成樹脂を言う。In this invention, a thermoplastic film that melts due to heat during autoclave curing refers to heat during high-temperature, high-pressure steam curing in an autoclave, specifically 100°C to 180°C.
This refers to a thermoplastic synthetic resin film that melts due to the heat applied to it, and the resin that does not melt refers to a thermoplastic synthetic resin that has a melting point above the above temperature range.
そして、上記二種類のフィルムを積層し、溶融しやすい
フィルム面を建築用無ａＸ板材の表面に接して敷設し、
オートクレーブにより高温高圧蒸気養生すれば建築用板
材表面に熱溶融したフィルムが密着し、これがバインダ
ーとなってオートクレーブの熱により溶融しないフィル
ムが板材表面に密着されるのである。Then, the above two types of films are laminated, and the film surface that is easy to melt is laid in contact with the surface of the non-aX architectural board material,
When cured with high-temperature, high-pressure steam in an autoclave, a thermally fused film adheres to the surface of the construction board, and this serves as a binder, allowing the film that does not melt due to the heat of the autoclave to adhere to the surface of the board.
［実施例〕 次にこの発明の詳細な説明する。[Example〕 Next, this invention will be explained in detail.

A film IB made of a 0μ low density polyethylene resin is laminated to form a laminated film 1, and then this laminated film 1 is placed on an inorganic plate material 2 manufactured by a papermaking method.
The plate was laid with the side of the film having a lower melting point facing downward, and at the same time as the unevenness 3 was formed on the surface of the plate by pressing, the film 1 was brought into close contact with the plate. Next, after primary curing, the plate-shaped body was subjected to high-temperature steam curing at 150° C. for 8 hours in an autoclave.

Since the heat-melting film is melted by the heat of an autoclave and adhered to the plate side surface, there is no need to apply adhesive, etc., and it is possible to achieve strong adhesion, and the surface decorative layer is completely covered with the synthetic resin film. It has very good water resistance, and can be formed into a decorative layer that can exhibit sufficient water resistance and strength as an exterior wall material or roofing material.
