Description of the Related Art Paints using synthetic resin emulsions and marble powder and other aggregates and colored aggregates such as colored silica sand or colored ceramic powder have been used as exterior paints for buildings having natural stone-like patterns. I have. However, stone powder, silica sand, and other aggregates used in such paints are very easy to transmit heat, and compared to resin-based paints such as elastic paints widely used for exteriors. Very easy to transmit heat. In recent years, in order to control a temperature change inside a building, such as energy saving and prevention of dew condensation inside a wall surface, it has been widely practiced to arrange a heat insulating material such as styrene foam or glass wool on the inside and outside surfaces of a building wall. On the other hand, as a coating material for imparting heat insulating properties, those using an inorganic or organic fine foam or a fine hollow foam as an aggregate are known. For example, an invention relating to a thick film type elastic heat insulating coating material using styrene foam particles and an elastic resin emulsion (Japanese Patent Application Laid-Open No. 10-152648) has been proposed. However, a coating film using an elastic resin emulsion has been proposed. In addition, because the foam is soft, if a hard topcoat material like stone is applied to the top coat, the heat insulation layer will be distorted by impact, cracks and peeling of the top coat will easily occur, and as an intermediate coat of stone coat Cannot be used. In the invention of Japanese Patent Application Laid-Open No. 6-100796,
A thermal insulation coating material has been proposed in which a cold-linkable synthetic resin emulsion is mixed with an inorganic powder obtained by blending white cement and silica sand with a main ingredient of shirasu balloon, but since cement is used, a number of materials after mixing have been proposed. There is a problem that curing takes place in a long time, and it takes time in material management such as pot life.

とするものである。The present invention not only can improve the poor heat insulating property of the stone-like coating layer, but also can apply the heat-insulating coating layer even if the hard stone-like coating layer is applied as an overcoat layer. The layer is hardly distorted, and the stone-like coating layer, which is the overcoat layer, is not easily cracked or peeled off.
It is another object of the present invention to provide a heat-insulating coating structure having a stone-like appearance that does not require much labor in terms of material management such as pot life.

It is composed of an inelastic coating film formed by a coating composition containing a heat insulating material containing a fine foam or a fine hollow body, and the stone-like coating layer is formed by adding stone-like particles to a resin component for coating.

Preferably, 70 or more coatings are required. Therefore, it is desirable to use a resin component having a low elasticity as the non-elastic resin component for paint. However, as long as the final coating film hardness can be obtained, the elasticity of the resin itself is appropriately changed. I can do it. Incidentally, the coating film hardness may be 60 or more, preferably 70 or more, but if it is too hard, the flexibility of the heat insulating coating layer is lost, and the ability to follow the distortion of the substrate and the adhesion to the undercoat layer are reduced, In consideration of cracking of the coating layer, it is preferably 100 or less, more preferably 90 or less.

ない。Examples of the heat insulating material include inorganic fine foams such as perlite, volcanic rubble, and perculite; fine hollow foams such as shirasu balloons, glass balloons, and silica balloons; and resin foams such as expanded polystyrene, expanded polyethylene, and expanded polyurethane. And fine hollow particles made of resin such as vinylidene chloride-acrylonitrile resin and acryl-styrene resin. One or more of these materials can be selected and used. As the heat insulating material, it is desirable to use a material that is harder than the styrofoam particles. However, as described above, the hardness of the coating film containing the heat insulating material is a durometer hardness tester (measured in JIS K6253) type. If the E-type measuring device can achieve 60 or more, preferably 70 or more, the hardness of the heat insulating material itself can be changed as appropriate. Although the heat insulating material increases the heat insulating property by increasing the blending amount, if the blending amount is too large, the hardness of the coating film decreases or the coating film formation becomes difficult. It is appropriate to mix the volume%, but it is not necessarily limited to this as long as the appropriate heat insulating property is obtained and the coating film hardness is obtained.

Adhesive strength is measured by applying an epoxy adhesive to the surface of the coating, bonding a metal jig, cutting the coating along the jig until the coating reaches the base material, The film was pulled until peeled off, and the load was evaluated at the time of peeling. The impact resistance was evaluated by visually evaluating the appearance of the coating film after the ball drop test.

である。As described above, according to the present invention, not only can the poor heat insulating property of the stone-like coating layer be improved, but even if the hard stone-like coating layer is applied as the overcoat layer, the heat-insulating coating layer is not distorted. Providing a heat-insulating coating structure with a stone-like appearance that is less likely to occur, suppresses cracking and peeling in the stone-like coating layer that is the overcoat layer, and does not require labor in terms of material management such as pot life Is what I was able to do.
