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.

Means for Solving the Problems In the present invention, when applying a synthetic resin-based floor material to a floor base surface, after applying a primer containing a synthetic resin as a main component to the floor base surface, an essential component is contained in the synthetic resin. As a pigment, and / or a powdered colored fiber having a maximum size of 5 to 500 μm as a mixture, and a coated floor material prepared by mixing the powder and the coated surface to a dried surface. It is a construction method on the floor.

To explain further below, in the primer coating step, for the purpose of improving the adhesion of the coating floor material to the smooth floor base surface made of concrete or asphalt on the road surface or the floor surface inside or outside the building. The synthetic resin that constitutes the primer is a solution or emulsion type primer (sealer paint) of a synthetic resin such as an epoxy resin, a urethane resin, or an acrylic resin. Epoxy resin is most suitable in terms of adhesion, water resistance, chemical resistance, etc. 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.

As the synthetic resin constituting the floor coating material used in the step of coating the floor coating material, a chemical resistant epoxy resin, F.I. R. P. There are polyester resins, vinyl ester resins, elastic urethane resins, and acrylic resins with good workability, which are used as solvent-free type, solvent type, emulsion type, etc.

As a substance which gives a pointillistic feeling as an essential component mixed in a synthetic resin, an average particle size of 20 to 400
Pigment made of μm colored synthetic resin and maximum size 5 to 50
Examples include powdery colored fibers treated to 0 μm, and one or more kinds of colored 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 imparting the pointillistic feeling include, for example, the trade name Love Color [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 powdery colored fibers which give a feeling of pointillism 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 feeling of pointillism include, for example, trade name Cell Color (manufactured by Kojin Co., Ltd.), trade name Illumin (manufactured by Diamond Industry Co., Ltd.) and the like. Examples include powdery or needle-shaped colored fibers.

The amount of these pigments and / or colored fibers mixed is 0.1 to 150 parts by weight, and usually 5 to 50 parts by weight, based on 100 parts by weight of the synthetic resin for floor coating materials.

In addition to pigments and / or colored fibers which give a punctuation feeling, known coloring pigments for the purpose of coloring the floor coating material, for example, fine powdery coloring materials 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 for applying the floor coating material, it is desirable to apply a single color on a smooth surface to a uniform thickness using an application tool such as a trowel or a roller. The standard coating amount is about 1.5 kg / m ² , but it is determined by the desired appearance and function.

EFFECTS OF THE INVENTION According to the method for applying a coated floor surface of the present invention, a specific pigment and / or colored fiber that imparts a stippling sensation of mixing into the coated floor material gives a coated floor surface with excellent design. .

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

Further, as compared with the coated flooring material in which the lightweight aggregate is mixed, since the hollow body is not contained, the strength of the surface and the whole layer is excellent. From the above, it is useful as a construction method for a floor of a house or a store where aesthetics are required.
