この発明は、無ａｔ建材の艶消塗装方法に関し、艷有塗
料で艶消塗装を行う無機質建材の艶消塗装方法に関する
。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a matte coating method for non-AT building materials, and more particularly, to a matte coating method for inorganic building materials in which matte coating is performed using a coating material.
従来、セメントを主原料として、瓦、壁板など建材を製
造することが広く行われている。Conventionally, building materials such as tiles and wallboards have been widely manufactured using cement as the main raw material.
しかし、上記無機質建材は、地色が灰白〜灰黒色の無彩
色であり、そのままであると意匠性に乏しく、また、表
面吸水性に冨むので、耐水処理を兼ねた表面塗装が通常
行われる。However, the above-mentioned inorganic building materials have an achromatic background color ranging from grayish-white to grayish-black, and if left as is, they lack design qualities, and the surface is highly water-absorbing, so surface painting that also serves as a water-resistant treatment is usually performed. .
上記塗装として艷有塗装と艶消塗装とがあり、外装壁板
、屋根瓦等建物外面に設けられる建材にあっては艶消塗
装が好まれる場合が多く、これら要請より艶消塗料によ
り塗装する場合も少なく無い。There are two types of above-mentioned coatings: matte coating and matte coating. Matte coating is often preferred for building materials installed on the exterior of buildings such as exterior wall boards and roof tiles, and due to these requests, coating with matte coating is performed. There are many cases.
しかし、艶消塗料は艷有塗料に較べて頗料が多く樹脂分
が少ないため耐候性が艷有塗料に較べ悪く、チョーキン
グ（白亜化）が生じやすい欠点があった。However, since matte paints contain more pigment and less resin than paints with lint, they have poor weather resistance and are prone to chalking (chalking).
この発明は、上記問題に鑑み、艶消塗装でありなから艷
有塗装と同様の耐候性を有する無機質建材の艶消塗装方
法を提供す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 matte coating method for inorganic building materials, which is a matte coating and has weather resistance similar to that of a coated coating.
即ちこの発明の無ｌｌ賞建材の艶消塗装方法は、瓦、壁
板などの無機質建材表面に艷を塗料を均一塗布し乾燥さ
せた後、前記と同質の艷有塗料をエアスプレー、または
エアレス塗装法により微粒子化して吹付け、該吹付は粒
子がレベリングしない間に乾燥硬化させることを特徴と
するものである。That is, the matte coating method for award-winning building materials of the present invention involves uniformly coating the surface of inorganic building materials such as roof tiles and wallboards with a coating material, and then drying the coating material. The particles are made into fine particles by a coating method and sprayed, and the spraying is characterized by drying and hardening the particles while they are not leveled.
この発明において使用する塗料は全て艷有塗料を使用す
る。All paints used in this invention are paints with paints.
下地となる無機質建材表面に先ず艷有塗料により均一塗
装し乾燥させる。First, the surface of the inorganic building material that will serve as the base is uniformly coated with the paint and allowed to dry.
この１ｇにより表面の耐水性、耐候性が付与される。This 1 g imparts water resistance and weather resistance to the surface.
しかしこのままでは表面が艶を有し艶消とは成らない。However, if left as is, the surface will be glossy and will not be matte.
そこでこの乾燥塗膜上に前記と同質の艷有塗料をエアス
プレー、またはエアレス塗装法により微粒子化して吹付
け、該吹付は粒子がレベリングしない間に乾燥硬化させ
るのである。Therefore, a coating material having the same quality as above is sprayed onto this dried coating film after being made into fine particles by air spray or airless coating method, and the spraying is performed to dry and harden the particles while the particles are not leveling.
このレベリング防止は基材温度を上げ塗着微粒子を急激
に乾燥させるほか、被塗物とスプレーガンとの距離を離
し、均一付着できる最小の塗布量に調整することにより
実施される。This prevention of leveling is achieved by increasing the temperature of the substrate to rapidly dry the coated particles, increasing the distance between the object to be coated and the spray gun, and adjusting the amount of coating to the minimum that will allow for uniform adhesion.
従って前記艷有塗装面上には微粒子化した塗料が均−分
散状に付着するので、この微粒子が外来光の乱反射を行
う結果、艷有塗装面があたかも艶消塗装面のような外観
を呈する。Therefore, the finely divided paint adheres to the coated surface in a uniformly dispersed manner, and as a result of these fine particles diffusely reflecting external light, the coated surface appears as if it were a matte painted surface. .

つまで組み合わせて実施される。In addition, the conditions for preventing leveling of spray paint are paint viscosity 10-50 seconds/Iwata cup, temperature of coated object 20-120 seconds.
°C, spray pressure 0.8 to 5-/-, spray gun diameter 0

It is carried out in combination.
また塗料はアクリル系、フッソ系、ウレタン系など任意
の艷有塗料の使用が可能である。Furthermore, any paint can be used, such as acrylic, fluorine, or urethane paints.
次にこの発明の詳細な説明する。 Next, this invention will be explained in detail.
