Description
【発明の詳細な説明】 〔産業上の利用分野〕 この発明は化粧外壁材の製造方法に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a method for manufacturing decorative exterior wall materials.
（従来の技術〕
セメント配合物より内外壁板を製造することが広く行な
われているが、これらＳＰＳ質壁仮は、そのままである
と素材の色彩が灰〜黒灰色の無彩色で意匠性が乏しいた
め、表面に耐水性付与を兼ねて各種色彩の塗装が施され
るのが通常である。(Prior art) It is widely practiced to manufacture interior and exterior wall boards from cement mixtures, but if these SPS wall panels are used as is, the color of the material is gray to black-gray and has no design value. Because of its scarcity, the surface is usually coated with various colors to provide water resistance.
この塗装手段として、養生前の未硬化板材表面にエマル
ジシン塗装を行ない、板材の養生硬化と同時に塗膜強化
を行なうことや、−次養生後に下塗り、及び上塗りを施
し、乾燥することなどが行なわれている。As a means of this coating, emulsion coating is applied to the surface of the uncured board material before curing, and the coating film is strengthened at the same time as the board material is cured and cured, and after the next curing, an undercoat and a top coat are applied and dried. ing.
しかしながら、従来の塗装法は基材となる板材表面に塗
料を塗布するものであるから、いかに耐候性の良い塗料
を使用しても経年劣化による剥離脱落は避は得す塗膜の
脱落があれば、その部分の耐水性は著るしく低下すると
共に地色が露出するので見苦しくなるといった欠点が有
った。However, conventional painting methods apply paint to the surface of the base material, so no matter how weather-resistant the paint is, it is inevitable that the paint will peel off due to age-related deterioration. For example, the water resistance of the area is significantly reduced, and the background color is exposed, making it unsightly.
この発明は上記問題点に鑑み、経年劣化による塗膜劣化
が生じても、外観低下、並びに耐水性の低下を防止し得
る化粧外壁材の製造方法を提供することを目的としてな
されたものである。This invention was made in view of the above-mentioned problems, with the purpose of providing a method for manufacturing decorative exterior wall materials that can prevent deterioration in appearance and water resistance even if the paint film deteriorates due to aging. .
（課題を解決するに至った技術）
即ち、この発明の化粧外壁材の製造方法は常法配合に従
ったセメント配合物に対し顔料の色彩、隠蔽力に応じ、
２〜５重量％の顔料を添加し、該顔料添加セメント配合
物を用いて長網式多層抄造法により板材を製造し、該成
形板材表面に前記顔料と同系統の表面塗装を行なうこと
を特徴とするものである。(Technology that has solved the problem) That is, the method for manufacturing decorative exterior wall materials of the present invention is based on the method of manufacturing a decorative exterior wall material according to the color and hiding power of the pigment, in contrast to the cement mixture according to the conventional formulation.
It is characterized by adding 2 to 5% by weight of a pigment, producing a plate material by a fourdrinier multilayer papermaking method using the pigment-added cement mixture, and applying a surface coating of the same type as the pigment to the surface of the formed plate material. That is.
この発明において使用されるセメント配合物は、従来、
長網式多層抄造法に用いられる配合と同じで良く、特に
記する点は無い。The cement formulation used in this invention is conventionally
The formulation may be the same as that used in the Fourdrinier multilayer papermaking method, and there is no particular point to note.
ただし、上記配合には顔料の色彩、隠蔽力に応じ、２〜
５％の顔料が添加される。However, depending on the color and hiding power of the pigment, the above formulation may be
5% pigment is added.
この顔料添加の理由は、ベース基材となるセメント板に
対し、着色を行なうと同時にある程度の耐水性を付与す
るためである。The reason for adding this pigment is to color the cement board serving as the base material and at the same time impart a certain degree of water resistance.
添加量が２重量％より少ないと、着色効果並びに耐水効
果が得られず、５重量％より多くすると顔料添加による
セメントマトリックスの強度低下が生じるおそれがある
。If the amount added is less than 2% by weight, the coloring effect and water resistance effect cannot be obtained, and if it is more than 5% by weight, the strength of the cement matrix may decrease due to the addition of the pigment.
また、この発明において、長網式多層抄造法とするのは
抄造法とした場合、顔料により着色された排水処理がや
っかいとなり、また、乾式法では顔料の均一混合が容易
でなくなるためである。Further, in the present invention, the Fourdrinier multilayer papermaking method is used because, if the papermaking method is used, the treatment of wastewater colored by pigments becomes troublesome, and in the dry method, uniform mixing of the pigments is not easy.
そして、上記配合材料で成形された板材表面には、未硬
化又は−次養生の段階で表面に前記顔料と同系統の色彩
の着色塗装が施される。Then, the surface of the plate material formed from the above-mentioned compounded material is painted with a color similar to the above-mentioned pigment at the uncured or post-curing stage.
板材はこの表面塗装により表面化粧されるが、経年劣化
により塗膜が剥落しても地色が同系統の色彩であるため
、目立たず、また、添加顔料によりベース基材の耐水性
もある程度付与されているため、耐水性についての著る
しい低下もさけられる。The surface of the board material is decorated with this surface coating, but even if the coating peels off due to aging, it will not be noticeable because the ground color is the same color, and the added pigment will also provide some degree of water resistance to the base material. Therefore, a significant decrease in water resistance can be avoided.

得た板材の物性が優れることが判明した。After curing and curing, an accelerated weather resistance test was conducted using a sunshine weather device on 3-day-old materials.
The plate material obtained by this invention has a color difference ΔB after 2000 hours.
= 2.5, whereas the conventional emulsion coating on a pigment-free base material showed a color difference ΔE = 4.5 after the same 2000 hours, and the color difference ΔE = 4.5 was obtained using the present invention. It was found that the physical properties of the plate material were excellent.
この発明は以上説明したように、ベース基材そのものを
