に満足する塗膜の形成方法は未だ提案されていない。(Conventional technology and problems) In recent years, due to changes in architectural styles, water vapor generated inside buildings is not discharged from the exterior walls, causing various problems due to internal condensation and destruction of the materials that make up the exterior walls (so-called frost damage). Cases of blistering and peeling of exterior wall paint are increasing. In response, various coating materials with moisture permeability have been proposed, but
There are advantages and disadvantages in the balance of moisture permeability, waterproofness, weather resistance, etc., as well as workability in winter, and a coating film that comprehensively satisfies a variety of aesthetic protection functions that correspond to the diversification of architectural styles. A method for forming this has not yet been proposed.

材を塗付する第１工程。(Means for Solving the Problems) In view of the above problems, the present invention provides a method for forming a coating film that comprehensively satisfies a wide variety of aesthetic protection functions that correspond to the diversification of architectural styles. When forming a moisture permeable multi-layer coating film, the first step is to apply an undercoat material having a moisture permeability of 50=150g/1rr-day.

The transportation humidity is low, and the transportation humidity near the outside is high, so that water vapor molecules are not retained in the coating film (they are discharged to the outside).
重要なことは、各々の構成材料が上記の各機能と共に通
切な範囲の透湿度を有していることであり、このバラン
スがくずれると初期の目的は達成できない。What is important is that each constituent material has the above-mentioned functions and moisture permeability within a reasonable range; if this balance is lost, the initial objective cannot be achieved.
次に各構成要素として、利用できる塗材について述べる
。Next, we will discuss the coating materials that can be used for each component.
まず第１に、塗材の顔料として、表面が多孔質構造を持
つ顔料を用いた構成塗材が挙げられる。First of all, there are constituent coating materials that use pigments whose surfaces have a porous structure as pigments in the coating materials.
ここで、表面が多孔質構造を持つ顔料とは、ゼオライト
、焼成りレー、珪藻土、シリカゲル等であり、表面の多
孔質構造により一定の透湿性効果が得られるように適宜
配合すればよく、その他の塗膜構成要素は、一般に用い
られる全ての材料が利用できる。Here, pigments with a porous surface structure include zeolite, calcined clay, diatomaceous earth, silica gel, etc., and may be blended as appropriate to obtain a certain moisture permeability effect due to the porous surface structure. All commonly used materials can be used as the coating components.
次ぎに、特に中塗材においてはその目的機能から、比較

、タルク、珪藻土、珪砂、硫酸バリウムから選ばれる少
なくとも１種以上が、全顔料の６０重量％以下の場合、
透湿度において良好な結果が得られないことを、本発明
者らは実験により確認している。Next, because intermediate coating materials in particular require a relatively thick coating due to their intended function, pigments such as calcium carbonate, clay, talc, diatomaceous earth, silica sand, and barium sulfate with an average particle size of 5μ or more are used. Good results can be obtained by using at least one of the selected pigments in an amount of 60% by weight or more of the total pigment.
This is also related to the fact that PVC is a condition.
When the average particle size is 5μ or less, or when at least one selected from calcium carbonate, clay, talc, diatomaceous earth, silica sand, and barium sulfate accounts for 60% by weight or less of the total pigment,
The present inventors have confirmed through experiments that good results in moisture permeability cannot be obtained.

素として好適に利用されることを、実験の結果見いだし
た。このポリウレタン系の塗膜は主として下塗、仕上材
に利用されるが、中塗材のバインダー成分として用いる
ことを妨げるものではない。Furthermore, as a result of experiments, it has been found that a so-called polyurethane coating film composed of various polyols and polyisocyanates can be suitably used as a constituent element of the present invention. This polyurethane-based coating film is mainly used as an undercoat and a finishing material, but this does not preclude its use as a binder component in an intermediate coating material.
また、特に中塗材及び仕上材の構成塗材のｐｖＣや使用
バインダーのガラス転移温度を調整し、これら複合塗膜

It is possible to add a function to follow the upper frame crank, making it an extremely preferable usage form.

合的に満足する塗膜を形成することが可能となる。Thus, by sequentially forming each constituent coating material disclosed above to have a predetermined moisture permeability, it is possible to create a coating that comprehensively satisfies a wide variety of aesthetic protection functions that correspond to the diversification of architectural styles. It becomes possible to form a film.
