る。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coating composition, and more particularly to a coating composition capable of forming a coating film having an appearance similar to natural stone and a soft surface feel.

Among these surface-coating paints, those that give the appearance of a natural stone pattern to the surface of the material have recently become widely preferred as exterior paints for building materials and interiors.

は未だ開発されていないのが現状である。[0004] However, although the conventional coating compositions are relatively excellent in giving an appearance close to that of natural stone, the coating efficiency and the coating operation when actually applying the coating are considered. It is not necessarily good enough in terms of point. This is considered to be due to the fact that material particles having a relatively large specific gravity such as silica sand and inorganic pigment (for example, natural colored sand or colored porcelain granules) are mixed into the coating composition. Furthermore, in the conventional paints, the main purpose is to impart a natural stone-like appearance to the formed coating film, and a coating material that has been sufficiently considered in terms of improving the texture or feel of the coating film surface itself has not yet been developed. It has not been developed yet.

It is an object of the present invention to provide a coating composition.

Both have been found to improve.

More specifically, the present invention relates to a coating composition which gives a coating film having an appearance similar to natural stone and a soft touch, and comprises a synthetic resin binder 20 To 55% by weight, 30 to 80% by weight of colored aggregate having a particle diameter of 400 μm or less, and 1 to 15 of transparent synthetic resin beads having a particle diameter of 10 to 100 μm.

It is desirable that these film-forming binders be selected in consideration of durability and weather resistance according to the application member and application of the paint. Specific examples of the synthetic resin binder include, for example, epoxy resin, urethane resin, acrylic resin, ethylene-vinyl acetate copolymer, styrene-acrylate copolymer, acrylate copolymer, vinyl acetate-acryl copolymer, Vegetable vinegar copolymer, acrylic-silicone copolymer and the like, and these reaction curable resins and their solutions and emulsions are preferably used.

くない。The synthetic resin binder is preferably contained in the range of 20 to 55% by weight based on the coating composition. When the amount is less than 20% by weight, the effect as a binder is hardly exhibited, and for example, cracks easily occur on the coating film surface. On the other hand, if it is added in an amount exceeding 55% by weight, the binder effect is saturated and the cost is disadvantageous, and the drying step after coating takes too much time, which is not preferable.

効率を改善することができる。As the colored aggregate, a material conventionally used for giving a natural stone pattern can be used.
In the present invention, it is particularly preferred to use inorganic particles such as silica sand whose surfaces are colored by a glaze, or colored resin particles colored with a pigment or dye. Among such colored aggregates, in particular, by using the surface of the inorganic resin particles colored by a glaze or the like, it is possible to obtain a coating film having an appearance more similar to natural stone, and to use the transparent synthetic resin beads described later. In combination with the effect of the combination, the coating efficiency at the time of coating can be improved.
【００１１】上記着色骨材の粒径は、特に４００μｍ以
下に制限することが、自然石に近い外観を発現させる上
において肝要である。さらに好ましい着色骨材の粒径範
囲は、１００〜４００μｍである。It is important to limit the particle size of the colored aggregate to 400 μm or less, in particular, in order to develop an appearance close to natural stone. A more preferred particle size range of the colored aggregate is 100 to 400 μm.

好ましくない。Further, the mixing range of the colored aggregate is 30
~ 80% by weight is preferred. When the amount is less than 30% by weight, it is insufficient to provide a good natural stone pattern. On the other hand, when the amount is more than 80% by weight, the coating efficiency is reduced and the strength of the formed coating film is also low. It is not preferable because the size becomes small, cracks occur in the coating film, and aggregate particles easily fall off from the coating film surface.
【００１３】上述した着色骨材の製造方法としては、た

重合することによって製造できる。In the case of an inorganic colored aggregate, an aggregate material such as silica sand and a glaze slurry are mixed and dried at 200 to 300 ° C. to give glaze slurry-coated aggregate particles. In the case of colored resin particle aggregate, the resin and the pigment are melt-kneaded and then pulverized, or the pigment is mixed with a monomer component constituting the resin, and the mixture is suspended. It can be produced by polymerization.

脂、エポキシ樹脂などの材料が好ましく用いられ得る。Further, in the coating composition of the present invention, it is one of the important features to add transparent synthetic resin beads in addition to the above components. Such transparent synthetic resin beads (preferably spherical) are not particularly limited. For example, acrylic resin, styrene resin, styrene-acrylic resin, acrylonitrile resin, urethane resin, polyamide resin, polyethylene resin, A material such as an epoxy resin can be preferably used.

If the amount is more than 15% by weight, beads overlap in the coating film to be formed, and this portion becomes a white spot, or the entire coating film becomes cloudy.
