Description
【発明の詳細な説明】 〔産業上の利用分野〕 この発明は無機質押出成形体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 an inorganic extruded body.
従来、瓦として繊維補強セメントよりなるセメント瓦が
非常に広く使用されている。Conventionally, cement tiles made of fiber-reinforced cement have been very widely used as roof tiles.
これらセメント瓦は、基材が吸水性を有すること、及び
地色が灰〜灰黒色で装飾性に乏しいため、防水性付与を
兼ね表面に着色化粧が施されるのが通常である。Since the base material of these cement tiles has water absorption properties and the base color is gray to grayish black, they are poor in decorative properties, so the surface of these cement tiles is usually painted with a colored decoration in order to provide waterproof properties.
これら、セメント瓦の化粧方法としては、セメント配合
物を押出成形後、これを製品寸法に切断し、プレス機へ
供給し、プレス盤で加圧後、表面にセメントスラリー塗
装、次いでエマルジッン系、又は溶剤系樹脂塗料で塗装
し養生硬化させることや、セメント配合物を押出成形後
、プレス、切断したものを一次養生して硬化させた後に
表面にエマルジョン系樹脂塗料、溶剤系樹脂塗料により
下塗、上塗を施し、養生硬化するという方法が行なわれ
ている。These cement tiles are decorated by extruding the cement mixture, cutting it into product dimensions, supplying it to a press, pressurizing it with the press, painting the surface with cement slurry, and then applying emulsion or Painting with solvent-based resin paint and curing and curing, or extrusion molding of cement mixture, pressing, cutting, primary curing and curing, and then undercoating and topcoating with emulsion-based resin paint or solvent-based resin paint. The method used is to cure and harden the material.
しかしながら、前者の化粧方法では、表面のトップコー
ト層が劣化するのは避けられず、1〜3年で劣化剥離し
始めると、下部層のスラリー層が露出してしまうため、
化粧効果が消失してしまう欠点があった。However, with the former cosmetic method, it is unavoidable that the top coat layer on the surface deteriorates and begins to peel off after 1 to 3 years, exposing the slurry layer below.
There was a drawback that the makeup effect disappeared.
又後者の化粧方法では、−次養生後、乾燥した製品表面
に塗装するので基材に対する塗料の密着性が前者の化粧
方法に較べて悪く、瓦として屋根上に葺いた場合、紫外
線、水、熱による劣化があり、3〜5年で塗膜が剥離し
表面が見苦しくなるといった問題があった。In addition, in the latter cosmetic method, the adhesion of the paint to the base material is poorer than that in the former method because it is painted on the dry surface of the product after curing. There was a problem of deterioration due to heat, and the coating film peeled off after 3 to 5 years, making the surface unsightly.
この発明は上記問題点に鑑み、無機質押出成形体の表面
化粧層が、耐候性、耐熱性、耐水性、耐日光堅牢度など
、耐用寿命の改良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 was made with the aim of improving the service life of the decorative surface layer of an inorganic extrusion molded product, such as weather resistance, heat resistance, water resistance, and fastness to sunlight.
即ち、この発明の無機質押出成形体の化粧方法はセメン
ト配合物を押出成形、切断、プレス成形を行なった後、
該成形体の表面に、セメント30〜40重量部、珪砂3
0〜40重量部、顔料5〜10重量部、耐熱性樹脂20
〜30重量部、水10〜20重量部より成る塗料で一次
塗装を行い強制乾燥後、該一次塗装表面に100重量部
中着色インク1〜5重量部、耐熱性樹脂塗料80〜95
重量部、残部を水とした塗料で二次塗装し、オートクレ
ーブ養生を行うことを特徴とするものである。That is, the method for decorating an inorganic extruded body of the present invention involves extruding, cutting, and press-molding a cement mixture, and then
30 to 40 parts by weight of cement and 3 parts by weight of silica sand are added to the surface of the molded body.
0 to 40 parts by weight, 5 to 10 parts by weight of pigment, 20 parts by weight of heat-resistant resin
A primary coating is applied with a paint consisting of ~30 parts by weight, 10 to 20 parts by weight of water, and after forced drying, 100 parts by weight, 1 to 5 parts by weight of colored ink, and 80 to 95 parts by weight of a heat-resistant resin paint are applied to the surface of the primary coating.
It is characterized by applying a secondary coating with a paint containing part by weight and the balance being water, and curing in an autoclave.
この発明に用いる耐熱性合成樹脂エマルジョン塗料とは
、合成樹脂が架橋型、又は自己架橋型で構成された反応
型エマルジョンをいう。The heat-resistant synthetic resin emulsion paint used in this invention refers to a reactive emulsion composed of a crosslinked or self-crosslinked synthetic resin.
従来用いられている合成樹脂エマルジョンの大多数は非
架橋型のもので、非架橋型のものは水分が蒸発すれば皮
膜を形成するが、本発明で使用する架橋型、自己架橋型
のものは水分が蒸発すれば皮膜を形成し、更に熱を加え
る事に依って架橋反応に依り分子の網状化が行なわれ、
耐熱性、耐水性、高強度の皮膜を形成するものである。The majority of conventionally used synthetic resin emulsions are non-crosslinked, and non-crosslinked types form a film when water evaporates, but the crosslinked and self-crosslinked types used in the present invention When the water evaporates, a film is formed, and when heat is applied, a crosslinking reaction occurs, forming a network of molecules.
It forms a heat-resistant, water-resistant, and high-strength film.
従って、塗装後塗膜の硬化(指触乾燥)が非常に速く下
塗後、上塗工程に至る時間の短縮が図れる。Therefore, the coating film cures (dries to the touch) very quickly after painting, and the time from the undercoating process to the topcoating process can be shortened.
また上記塗料にはセメント及び珪砂が含まれるため、前
記樹脂の硬化に続いてセメント−珪砂の水和反応による
硬化が生じるので、−次塗装として極めて強靭な塗装膜
とすることが出来るのであ更にこの一次塗装表面に反応
性合成樹脂エマルジョン塗料と着色用インクを混合した
塗料で塗装する理由は、インキは着色するが透明感は損
なわない利点を利用したもので、−次塗装に用いた顔料
に依る着色を更に鮮明にするためである。Furthermore, since the above-mentioned paint contains cement and silica sand, subsequent hardening of the resin is followed by hardening due to the hydration reaction of cement and silica sand, making it possible to form an extremely tough coating film for the subsequent coating. The reason why the primary coating surface is painted with a mixture of reactive synthetic resin emulsion paint and coloring ink is to take advantage of the advantage that the ink colors but does not impair transparency, and the pigment used in the secondary coating This is to make the coloring even clearer.

粧板を製造することができるなど種々の効果を有する。As explained above, this invention provides a first fI! After coating and drying, it is coated with a paint containing a heat-resistant synthetic resin mixed with colored ink, so it dries quickly to the touch even if the cement component has not yet hardened during the painting process. This increases the transfer speed in the painting process, improving production efficiency, and since the cement-silica component contained in the paint hardens during curing, the overall strength of the paint film becomes extremely strong, reducing peeling and other problems. Since it is coated with a transparent film that is less likely to cause oxidation and has good sunlight fastness, it has various effects such as being able to produce a decorative board with excellent weather resistance and excellent color clarity.
