満足させるためには多大な労力および時間を要した。For example, concrete base materials are often exposed to the atmosphere, and synthetic resins are required to have water resistance and acid resistance to prevent damage to the base materials from acidic rainwater caused by sulfur oxides, nitrogen oxides, etc. in the atmosphere. Coatings such as these are used. When coating the surfaces of concrete base materials, steel materials, etc. with synthetic resins, it is important to completely cover the exposed surfaces of the concrete base materials, steel materials, etc. so that no pinholes remain. Since there are many large and small pores on the surface of the concrete base material, it took a great deal of effort and time to satisfy the above requirements.

時間を要する等施工上に難点があった。In order to completely protect the substrate surface and provide complete corrosion protection by coating with a conventionally used coating composition, the substrate surface must be in a dry state when coating. In particular, when applying organic solvent-based paint or molten resin to concrete products, it is necessary to go through a sufficient drying process, which poses difficulties in construction, such as the long time required for the work process. .

径が大きすぎると得られる組成物の高粘度化、流動性の
低下等によ）作業性が低下する。By mixing a synthetic resin powder with a color vehicle, it is possible to obtain a coating composition that exhibits excellent adhesion to substrates, water resistance, and acid resistance, as well as excellent workability. The synthetic resin powder can be prepared by any known method, preferably about 200 μm or less, more preferably FJ5 to 100 μm.
It is used after adjusting to μ. That is, if the particle size of the synthetic resin powder is too large, the workability of the resulting composition decreases (due to increased viscosity, decreased fluidity, etc.).

ない。If the amount of synthetic resin powder blended is too small, water resistance and acid resistance will decrease, which is not preferable. If too much synthetic resin powder is blended, the resulting composition will have a high viscosity, which will cause problems in the application process, and the formed coating will lack a color vehicle, causing problems such as concrete, steel, and metal. This is not preferable because sufficient adhesion to the base material such as material cannot be obtained.

ができるが作業環境上好ましくない。The coating composition of the present invention is prepared by stirring and mixing a color vehicle and water, dispersing or emulsifying the color vehicle in water in the presence or absence of a dispersant or emulsifier, and then adding synthetic resin powder. By adding and stirring and mixing, it is made into a paint. In this case, if necessary, conventional additives such as viscosity modifiers and antifreeze agents, and organic fibers such as vinylon fibers and polyethylene fibers can be blended to prevent cracking of the coating film and adjust fluidity.
