とする工法に関する。TECHNICAL FIELD The present invention relates to a method for finishing an outer wall in an outer insulation method, and more specifically to a heat insulating material for the outer insulation method by using an aqueous reaction curing type resin. The present invention relates to a construction method that protects an organic foam and allows any construction finish coating material to be freely constructed.

することができず、一般に水性型エマルションペイント
やエマルション型建築仕上塗装材を使用していた。(Prior art) When an organic foam insulation such as polystyrene foam is used in the external insulation method, a solvent-type coating material should be used because the phenomenon of dissolution of the insulation due to the solvent in the paint occurs. However, water-based emulsion paints and emulsion-type architectural finishing paints were generally used.
このため耐候性、美装性、施工性等に限界があった。For this reason, there is a limit in weather resistance, beauty, and workability.

る。(Problems to be solved by the invention) There are foam insulating materials such as polyurethane foam, polyethylene foam, and inorganic foam aggregate, but polystyrene foam is used in view of cost, processability, and heat insulating property. Many are used. However, the heat insulating material of the polystyrene foam has a problem of poor solvent resistance.

付けする方法等である。The outline of the heat insulation method using this polystyrene foam insulation is to stick polystyrene foam on the outer wall concrete of a building as a heat insulation material, and then apply an inorganic material layer such as cement-based mortar or calcium silicate board on it. Alternatively, it is a method of pasting.

象が現れる。When a solvent-based coating material for building is applied to the wall surface of a building of this heat insulation method for the purpose of aesthetic appearance and protection of the wall surface, the polystyrene foam heat insulating material is an aromatic solvent which is a solvent component contained in the paint. It dissolves in a solvent such as a hydrocarbon, an aliphatic hydrocarbon, a ketone, an ester, a cellosolve, and an alcohol, and the effect of the heat insulating material disappears, and at the same time, the structure of the building wall surface is impaired.

It occurs because it penetrates into cement-based mortar and calcium silicate board and reaches polystyrene foam insulation.

いてもよい。That is, a calcium silicate board, a wood cement material, a dry inorganic material layer such as a dry siding board such as an asbestos slate board, or a wet cement inorganic material layer such as a mortar, a resin mortar or a resin filler is provided on the organic foam. A water-soluble or emulsion-type aqueous reaction-curable resin layer on the heat-insulating layer, for example, a solvent-resistant seal layer made of a water-soluble urethane resin such as polyether / polyol, polyester / polyol, or polycarbonate / polyol and its modified polymer. The sealing layer completely seals the solvent components of the solvent-based coating material for construction used as a decorative finishing layer, protects the organic foam, and allows any construction coating material to be freely applied. It is possible to install on. The solvent-resistant seal layer may be appropriately mixed with a pigment, a filler, various additives, etc., if necessary.
以下実施例により、本発明を具体的に説明する。Hereinafter, the present invention will be specifically described with reference to examples.

シール層を塗付し、16時間乾燥させて試験体とする。(Example) A cement polymer mixed slurry (cement-based filler) was applied to a polystyrene foam (thickness: 5 mm) to a thickness of 1 mm, and various sealing layers shown in Table 1 were formed on the heat-insulating layer dried for 176 hours. Apply it and dry for 16 hours to make a test sample.

Then, put 50 cc of lacquer thinner specified in JIS K 5538 into the funnel for 48 hours and then cement it. Observe the shape change of the polystyrene foam on the back of the filler.
この結果を表−２に示す。The results are shown in Table-2.

極めて有効な方法であることを見いだした。 (Effects of the Invention) From the results of the examples, the reaction-curable water-soluble urethane resin has a higher solvent sealing property than other water-soluble or water-dispersible resins, and is a heat-insulating material layer composed of a polystyrene foam and an inorganic material layer. It has been found that when a coating material for construction is applied, even if a solvent-based coating material is applied, it is an extremely effective method that does not adversely affect the polystyrene foam.

装材を自由に施工することが可能となる。By this method, polystyrene foam is used as an external heat insulating material in the building exterior insulation method, and it is possible to maintain the heat insulating function of the polystyrene foam for a long time even if a solvent type coating material is applied as the outer wall coating material. It becomes possible to freely apply various architectural coating materials for the purpose of improving aesthetic appearance, protecting wall surfaces, and improving other functions.
