DETAILED DESCRIPTION OF THE INVENTION
The coating film structure of the uneven surface of the present invention is a coating material in which a coating material and a colored aggregate of 10 μm to 150 μm are mixed on the surface of an object having an uneven surface where the height difference of the uneven portion is 0.5 mm to 15 mm. A coating film formed by the composition is laminated.
[0014]
First, a paint containing a colored aggregate of 10 μm to 150 μm can be finished in a variety of ways using an uneven surface, and is composed of a paint and a colored aggregate of 10 μm to 150 μm.
Examples of the paint include enamel paint by pigmentation, matte paint, transparent clear paint or color clear paint obtained by adding a pigment to the clear paint. The coating film formed by these paints is a thin film and can make use of the uneven surface.
[0015]
A transparent clear paint or a color clear paint obtained by adding a pigment to a clear paint is composed of a synthetic resin and other components. This synthetic resin is an acrylic resin, urethane resin, epoxy resin, melamine resin, alkyd resin, vinyl chloride resin, silicone resin, vinyl acetate resin, polyester resin, styrene resin, fluororesin or the like, Those obtained by dissolving these resins in an organic solvent or those dispersed in water as an emulsion are used. Synthetic resin emulsions are preferably used because of ease of use, ease of manufacture, and availability of paints .
[0016]
The synthetic resin emulsion may be a general one that can be produced by a conventional polymerization technique such as emulsion polymerization. Of these, acrylic synthetic resin emulsions and acrylic styrene synthetic resin emulsions prepared from acrylic resins and styrene resins are preferred from the viewpoints of paint suitability, physical properties of the coating film, and availability. You may select suitably according to the use and performance of a coating material .
[0017]
In the case of a color clear paint, a color pigment is used for coloring. The coloring pigments may be known ones, and inorganic and organic pigments and both can be added, and it is desirable to use those having good weather resistance.
[0018]
The amount of the color pigment added is preferably more than 0.0% by weight and 15% by weight or less of the active ingredient of the color pigment with respect to the resin solid content in the paint. If no color pigment is added, it is a clear paint. In that case, it is possible to make full use of the color tone of the colored aggregate and finish it in various ways. On the other hand, when the amount is more than 15% by weight, the hiding power is increased, the color tone of the colored aggregate described later cannot be utilized, and it may not be possible to finish in various ways.
[0019]
As other components, components generally blended in coating production such as low boiling point alcohol, high boiling point solvent, surfactant, thickener, pH adjuster, preservative and the like can be used. High-boiling solvents are used as film-forming aids and anti-freezing agents, and surfactants are used as antifoaming agents, dispersing agents, wetting agents and the like. A thickener is used for viscosity and viscosity adjustment.
[0020]
The paint preferably has a low hiding power. Those having a low hiding power can make full use of the texture and color tone of colored aggregates of 10 to 150 μm contained in the paint. Furthermore, it is possible to make use of the color tone of the surface of the object to be coated, and to obtain a more colorful finish.
[0021]
Those having a low hiding power are those having a dry coating film of 150 μm, preferably having a hiding ratio in the range of 0.00 to 0.50, and more preferably in the range of 0.00 to 0.30. When the dry coating thickness is 150 μm and the hiding power is 0.00, the color tone of the surface of the object to be coated and the color tone of the colored aggregate can be fully utilized. On the other hand, if it is larger than 0.50, the color tone of the colored aggregate described later cannot be utilized due to the concealment of the coating film, and it may not be possible to finish in various ways.
[0022]
The clear paint or the color clear paint has a solid content of 15 to 50% by weight, preferably 20 to 45% by weight. When the solid content of the clear paint or the color clear paint is less than 15% by weight, sufficient strength may not be given to the coating film. On the other hand, if it is larger than 50% by weight, it is difficult to paint, and spots may occur on the painted surface.
[0023]
The colored aggregate of 10 μm to 150 μm gives a colorful feeling to the surface to be coated having an uneven surface with a height difference of 0.5 mm to 15 mm in the height difference of the applied uneven portion by being included in the clear paint or the color clear paint. be able to. The colored aggregate is an aggregate having a color tone, and includes an aggregate having high transparency to an aggregate having high hiding power, an aggregate having gloss, and an aggregate having no gloss. A totally colorless and transparent aggregate has no color and is not a colored aggregate. However, a transparent colored aggregate having a color is a colored aggregate.
[0024]
These colored aggregates include those obtained by pulverizing colored natural stones, those obtained by pulverizing stones and ceramics, and those produced industrially. Colored natural stone pulverized materials include granite, serpentine, obsidian, fluorite, canary, white ball, cold water, small cherry blossoms, lacquered snow, Mino Pass, serpentine, etc. Sand).
[0025]
In addition, as a material obtained by artificially coloring a crushed stone, there is a method of coating a pulverized colored natural stone or quartz sand, cold water sand, or ceramic granule with a pigment, paint or glaze. Examples of industrially produced glass beads include glass beads having a substantially spherical glass shape, and plastic beads having a substantially spherical synthetic resin such as an acrylic resin. These can be colored from the inside in the manufacturing process of the aggregate.
[0026]
Compared with those obtained by pulverizing colored natural stones, artificially colored ones and industrially produced ones are preferred because both the particle size and color tone are stable, and the color tone when contained in a paint is also stable. In particular, artificially colored silica sand, cold water sand, and ceramic granule are more preferably used because they are easily available and have excellent miscibility with synthetic resins.
[0027]
Silica sand is mainly composed of silicon dioxide, and there are two types of natural sands, such as river sand and sea sand, and ones that have been sized by pulverizing silica stone. Is a pulverized cryogenic stone and adjusted in particle size. Ceramic granule is obtained by pulverizing ceramics, and is used after the particle size is adjusted after pulverization. Further, natural stones such as marble and granite that have been crushed to adjust the particle size can also be used. Glass beads are made of glass in a substantially spherical shape, and plastic beads are made of a resin such as an acrylic resin in a substantially spherical shape.
[0028]
The particle size of the colored aggregate is in the range of 10 μm to 150 μm, and preferably in the range of 45 μm to 150 μm. When the particle size is smaller than 10 μm, the particle diameter of the colored aggregate is too small, so that it is difficult to give a colorful feeling to the coating film, and it is difficult to contain it in the paint.
[0029]
When it is larger than 150 μm, the concave and convex portions of the concave and convex portions are filled and the concave and convex portions cannot be utilized. In addition, when painting with a spray gun, the spray gun may become clogged, or when painting with a painting roller, painting may be difficult, for example, it may be difficult to disperse aggregates larger than 150 μm without spots.
[0030]
The content of the colored aggregate of 10 μm to 150 μm is 10 to 50 parts by weight, preferably 15 to 30 parts by weight, based on 100 parts by weight of the clear paint or the color clear paint. When the amount is less than 10 parts by weight, it may not be possible to give a variety of feelings. When the amount is more than 50 parts by weight, the coating film becomes thick, the uneven surface cannot be utilized, and painting may be difficult. is there.
[0031]
