BACKGROUND ART The surfaces of inorganic products are generally hygroscopic or water-absorbing, so it is not very appropriate to use them as they are in construction board materials etc. from the viewpoint of waterproofness. Therefore, for exterior wall materials, roofing materials, etc., surface painting is performed in order to eliminate the above-mentioned problems and at the same time provide decorative properties.

However, when the above-mentioned inorganic products contain organic fibers as reinforcing fibers, if the surface of the product is polished or drilled prior to painting, the fibers will become loose, and since these fibers have flexibility, when applying the paint, There was a problem in that the fibers would fall down and stand up immediately after application, resulting in pinhole-like uncoated areas where the fibers had fallen down.

The technology that led to solving the problem The method of painting an inorganic product containing organic fibers of the present invention involves polishing or cutting the inorganic product containing organic fibers, and then applying a flame to the surface of the inorganic product before applying an undercoat. The product surface is preheated by direct contact with the product, and then the undercoat and topcoat are applied.

Function The inorganic products containing organic fibers to which this invention is applied are as follows:
Refers to an inorganic product manufactured using cement, gypsum, etc. as the main raw material, and which includes organic synthetic fibers such as vinylon fibers or natural organic fibers such as pulp fibers as reinforcing fibers.

Normally, this type of inorganic product is polished or cut, then preheated with warm air, etc., and then an undercoat is applied while the surface is in a high temperature state. However, in the present invention, As part of this preheating process, the flame from a gas burner is brought into contact with the surface of the product after polishing or cutting.
The heat generated at this time heats the surface of the product.

During this preheating process, the fuzzed organic fibers caused by the polishing process are burned off and disappear.

Moreover, at this time, the surface becomes temporarily heated, so
The air contained in the product surface layer also undergoes rapid thermal expansion and is expelled, so if you apply the undercoat immediately in this state, there is no risk of pinholes caused by air bubbles, and a uniform coating film will be created. is obtained.

そして、この下塗後、乾燥を行ない、次いで、必要回数

After this undercoating, it is dried, and then the final coat and drying process are repeated as many times as necessary to paint the product.

以下、この発明の方法を実施例により説明する。The method of the present invention will be explained below using examples.

Example 1 A cement board containing vinylon fibers and polypropylene fibers as organic fibers and having a thickness of 5 sheets and a width of 30 crIL in each direction was manufactured using the following composition.

Calcined gypsum 45 parts by weight Perlite 45 parts by weight Pulp fiber 6.7 parts by weight Vinylon fiber 2 parts by weight Polypropylene fiber 0.3 parts by weight Example 1
When the surfaces of the samples obtained in Example 2 and Example 2 were polished after curing, fluffing due to organic fibers was observed on the surfaces.

Next, flame was sprayed uniformly over the entire surface of the sample using a gas burner to burn off the protruding fibers, and the remaining burnt marks were lightly brushed with a spatula to remove them, and then an undercoat was applied with a solvent-based acrylic resin paint. , drying, then topcoating and drying were repeated once to complete the coating.

When the surfaces of these samples were observed with a magnifying glass, it was found that there were no defects such as bottle balls, and the painted surfaces were uniform and beautiful.

Effects As explained above, when painting an inorganic product containing organic fibers, which tend to become fluffy, this invention can wipe away the fluffy fibers by simply applying flame directly to the product as a preheating process. Moreover, at this time, the air on the surface of the product can also be removed, which prevents the occurrence of pinholes caused by air bubbles, and has the advantage that all processes, such as the treatment of fluffy fibers, can be completed in the second preheating process. .
