Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of applying a coated flooring material having a fine stippling feeling on the floor surface. It should be noted that the pointillistic tone uses the effect that fine color points are mixed in the visual sense in terms of appearance, and refers to the appearance in which the three-dimensional effect, soft feeling, depth feeling, etc., look slightly different depending on the viewing direction and angle. .

2. Description of the Related Art Painted pavement made of a coated floor material mainly composed of a synthetic resin such as an epoxy resin or a urethane resin for the purpose of improving functions such as waterproofness and chemical resistance on a road surface or a floor surface of a building or a rooftop. Has been applied.

In recent years, in addition to the above-mentioned demands for physical and chemical functions, there is a demand for appearance or function in terms of design, and pigments, colored aggregates, and colored lightweight bones are contained in resins for floor coating materials. There is also an increasing demand for a multi-layered pattern finish using a color-painted floor material in which a single color or two or more colorants such as wood (hollow body) is mixed.

[0004]

However, the color pavement in which the pigment is mixed in the resin is monotonous because it is monochromatic. Therefore, in the floor coverings that use colored aggregate for finishing the composite pattern, is the aggregate settling and the storage stability is poor?
The composition was likely to be non-uniform, and color unevenness was likely to occur in the appearance after construction. In addition, since the colored lightweight aggregate (hollow body) is used, since the aggregate is a hollow body, the aggregate easily cracks when the aggregate is mixed in the resin or when the coating material is applied to the floor surface. However, there was a problem in storability and workability.

An object of the present invention is to provide a method for applying a painted floor surface which has good storability of the painted floor material, has a uniform composition at the time of application, and is excellent in appearance and surface physical properties after application. It is in.

[0006]

According to the present invention, in constructing a stippled coating floor surface, the first step is to apply a primer containing a synthetic resin as a main component to the floor base surface, and as a second step. Coating a synthetic resin with a modifying agent or a coloring material to prepare a smoothing surface, and as a third step, the synthetic resin is a pigment made of a colored synthetic resin having an average particle size of 20 to 400 μm, and / Or the maximum dimension 5-500μ
This is a construction method for a pointillistic painting floor surface, which is characterized by finishing coating with a top coating material mixed with m powdered colored fibers and combining the above three steps.

More specifically, in the primer coating step of the first step, a smooth floor base surface made of concrete, asphalt, or the like is formed on the road surface or the floor surface inside or outside the building.
The purpose of this is to improve the adhesion of the coated flooring material.The synthetic resin constituting the primer is a solution or emulsion type primer (synthetic resin) of synthetic resin such as epoxy resin, urethane resin and acrylic resin. Among them, epoxy resin is most suitable in terms of adhesion, water resistance, chemical resistance and the like. Further, a color pigment, a filler (inorganic filler), etc. are appropriately mixed as necessary.

The primer coating method is concrete
After flattening the lower ground such as the gut, apply it by rubbing with an applicator such as a roller or brush. Reapply in areas where suction is severe. The standard coating amount is about 0.2 kg / m ² , but it is desirable to treat a smooth surface of a single color.

The synthetic resin constituting the undercoat material used in the second undercoating step is a chemical resistant epoxy resin,
There are low-viscosity unsaturated polyester resins for FRP, vinyl ester resins, rubber-elastic urethane resins, and acrylic resins with good workability, and they are used as solvent-free type, solvent type, emulsion type and the like.

For the purpose of imparting a function as a coating material, a defoaming agent, a plasticizer, a reactive diluent, a filler (such as an inorganic filler), and a modifier such as a coloring agent are added to the coating material. What is usually used as a floor covering is used. As a method of applying the undercoat material, a spatula, a trowel, a roller, or the like is used to prevent the generation of pinholes on the primer-coated surface, smooth the uneven surface, and make the hue uniform. The standard coating amount is about 1.0 kg / m ² , but it is desirable to finish it on a smooth surface.

As the synthetic resin constituting the top coat material used in the third top coat finish coating step, the synthetic resin and the modifying agent constituting the above base coat material are used.

Further, as a substance which gives a pointillistic feeling as an essential component mixed in the synthetic resin, an average particle diameter of 20 to
Pigment made of 400 μm colored synthetic resin and maximum size 5
Powdered colored fibers treated to ~ 500 μm can be mentioned,
One or more kinds of color substances are appropriately selected depending on the intended use and the desired design. The pigment that imparts a punctuation sensation has a larger particle size than pigments (titanium white, red iron oxide, etc.) used for ordinary coloring, and generally has an average particle size of 20 μm or more. If the particle size is too large, the pigment tends to settle and the storage stability is poor, so an average particle size of 400 μm or less is suitable. On the other hand, if the average particle size is less than 20 μm, the dot-spotting point is too small, and it is difficult to provide the designability as a dot-spotting tone.

Specific examples of the pigment that imparts the feeling of pointillism include, for example, Love Color (trade name, manufactured by Dainichi Seika Kogyo Co., Ltd.
Manufactured], spherical tyrone (manufactured by Tyoxiside), silica capsule giant particle pigment (manufactured by Sakai Chemical Industry Co., Ltd.), spherical polyester (manufactured by Kyoei Calcium), and so-called spherical pigments composed of colored synthetic resin. .

The powdered colored fibers which give a feeling of pointillization are powdered by treatments such as cutting, crushing and dry crushing, and those having a maximum size of 5 to 500 μm can be used. If the maximum dimension exceeds 500 μm and the maximum dimension is less than 5 μm, it is difficult to exhibit a design as a pointillistic tone. Since powdered colored fibers colored with a dye have a problem in weather resistance, it is preferable to use a pigment that can be dyed with a pigment. Those to which the property is imparted are listed.

Specific examples of the powdery colored fiber which imparts a punctuation feeling include, for example, trade name Cell Color (manufactured by Kojin Co., Ltd.) and trade name Illumin (manufactured by Diamond Industry Co., Ltd.). Examples include powdery or needle-shaped colored fibers.

The amount of the pigment and / or colored fiber that imparts the pointillistic feeling is mixed in the above-mentioned synthetic resin for floor coating materials 10
It is 0.1 to 150 parts by weight, and usually 5 to 50 parts by weight, relative to 0 parts by weight.

In addition to pigments and / or colored fibers which impart a punctuation feeling, known coloring pigments for the purpose of coloring the floor coating material, for example, fine powdery coloring agents such as titanium white, carbon and red iron oxide. It is also possible to mix and use, but in order to impart the desired pointillistic feeling, a coating resin in which only the pigment and / or colored fiber imparting the pointillistic feeling is mixed in an uncolored clear resin without addition is added. It is desirable to use floor materials.

If necessary, defoaming agents, preservatives, antifungal agents, and other known additives can be used.

As a method of applying the top coat material in the third step, it is desirable to apply it to a uniform thickness using an applicator such as a trowel or a roller. The standard coating amount is about 1.0 kg
/ m ² , but is determined by the desired appearance and function.

EFFECT OF THE INVENTION In the construction method of the stippled floor surface of the present invention,
A specific colored pigment and / or colored fiber mixed in the overcoat material applied to the surface smoothed with the colored undercoat material to give a pointillistic feeling can provide a coated floor surface with excellent design.

In addition, since the pointillistic feeling is imparted only in the topcoat material, the pointillistic feeling can be achieved even if the amount of the pointillistic tone imparting material is small compared to the finished appearance caused by mixing in the conventional mixed coating floor material. Appears clearly.

Further, since the specific gravity of the above-mentioned specific pigment and / or colored fiber imparting a pointillistic feeling is about the same as the specific gravity of the synthetic resin for floor coating material, it does not settle during storage and has good storability.
