Abstract

PURPOSE:To obtain a gorgeous and durable coated film by forming a desired rugged pattern on the substrate to be coated in a pearl tone and providing a pearl-toned coat layer so that the rugged pattern remains. CONSTITUTION:In the coating to form a colorful pearl-toned coated film, a base coating material for undercoating is coated on a wall surface 1 to form a substrate 3 having a rugged pattern on the surface. Then a pearl-toned coating matching to the color of the substrate is applied to the upper surface of the substrate 3 to form a coat layer 4 on which the rugged pattern 2 of the substrate 3 is made almost to remain. Consequently, a shade pattern is provided to the pearl-toned surface gloss of the coated film depending on the lines of light and sight, hence the pearl tone is varied, gorgeousness is enhanced and the resistance to weather and water is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] This invention relates to a coating method for producing a variety of pearl-like coating films.

[Conventional technology]

In the conventional pearl-like coating method, a base coating material for the base is applied to the wall surface to form a smooth base, and a pearl-like coating material is applied on top of this base to form a coat layer.

[Problem that the invention seeks to solve]

However, because the surface of the coated surface created using this pearlescent coating method is flat, the pearlescent tone does not change depending on the angle of incidence of the light beam or the direction of the line of sight, resulting in a simple burl effect. .

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention provides a desired uneven pattern on the surface of the base, and forms a coat layer so that the uneven pattern of the base remains.

[Effect]

In the burl-like coating film applied according to this invention, light rays are reflected in various directions on the uneven surface of the base, so this reflected light passes through the pearl-like coating layer and its complementary color appears, giving it a beautiful shading pattern. At the same time, the pearl tone changes in various ways depending on the angle of incidence of the light rays and the angle of the viewer's line of sight.

〔Example〕

Embodiments of the invention will be described based on the accompanying drawings. In the burl-like painting method of the present invention, a base coating material colored, for example, silver, is applied to an existing wall surface 1 to form a base 3 having a desired thickness and having a desired uneven pattern 2 on the surface. The uneven pattern 2 of the base 3 is created by applying, for example, a white bary-like coating material corresponding to the base color to the upper surface of the base 3.
The coating layer 4 is formed and constructed so that substantially .

The base coating material is an aggregate of 70 to ♂0, such as Kansui Tsumugi crushed stone! 20 to 30 parts by weight of a cold-curing synthetic resin emulsion such as acrylic resin IIM as a binder, and small parts by weight of a dispersant, PH stabilizer, antifoaming agent, viscosity modifier, preservative, coloring pigment, etc. It is what was done. In addition, the base coating material may also use an inorganic material such as white cement or Portland cement as a binding material; in this case, aggregate 50 to 7
The mixing ratio is changed so that 0 parts by weight and 30-jOJt parts by weight of the inorganic binder are mixed. In addition, this base coating material is
Although white and black are the base colors, various colors other than these are used.

In order to obtain various color changes depending on the angle of incidence of the light rays, the base 3 is formed into various patterns in which the height of the unevenness and the size of the pattern are varied.

The bar μ tone coating material contains 3 to lθ parts by weight of an iris-colored bar pigment (manufactured by Merck Japan Co., Ltd., trademark registered Iriodin) of a desired light color mainly white;
It is mixed with 90 to 7 parts by weight of acrylic μ resin, which has excellent transparency, as a binder. In addition, as a binding material for this coating material, acrylic-polyurethane resin (-liquid type, two-liquid type), polyurethane resin (-liquid type, two-liquid type),
Room temperature curing fluororesins (-liquid type, two-liquid type), etc. are also used. When using a room temperature curing fluororesin, a coating film that is extremely weather resistant can be obtained. It is also possible to use the above resins in an emulsion form.

The coating layer 4 is formed by diluting the bar μ tone coating material with a special thinning solution to an extent that can be coated, and then spraying, painting or brushing.

The coating film applied by the bar/l/interval coating method according to the present invention can be applied to a variety of existing coatings, including those using lead-based pigments that are harmful to the human body, weather resistance, water resistance, and acid resistance. Compared to those using shell powder, which has poor alkali resistance and chemical resistance, and those using organic pigments, which have poor UV resistance and fade quickly, they are harmless to the human body and have good weather and water resistance. It has excellent properties such as durability and chemical resistance, and can be used not only for constructing the exterior walls of buildings, but also for manufacturing boards for building materials.

This painted surface has a necessary uneven pattern on the surface of the base, so the reflected light rays reflected in various directions on this uneven surface are transmitted through the coating layer 4 and their complementary colors appear, creating an even more diverse burl tone. It becomes shiny, and depending on the base color, you can get a layered color.

〔effect〕

As described above, according to the pearl-like coating method according to the present invention, a desired uneven pattern is formed on the surface of the base, and a burl-like coating layer is provided so that the uneven pattern remains on the surface of the base. This paint film has a pearl-like surface luster and is further given a shading pattern depending on the direction of the light rays and the direction of the line of sight, making the pearl-like color change in various ways, making it extremely luxurious and weather resistant. It also has excellent properties such as durability, water resistance, and chemical resistance.

Claims (1)

[Claims] In the pearlescent painting method, in which a base coating film is applied to the wall surface to form a base, and a pearlescent coat coating material is applied to the top surface of this base to form a coat layer, a desired uneven pattern is formed on the surface of the base. This pearlescent coating method is characterized by forming a coating layer so that the uneven pattern of the base remains.
