Abstract

PURPOSE:To form a three-dimensional surface with the edge sharpened by coating the surface of a body to be coated with the substrate film of an adhesive medium formed on the part corresponding to the protrusion of the three- dimensional surface with a powder paint and removing the powder paint at the part not having the substrate film by utilizing the difference in adhesion. CONSTITUTION:The surface of a body 1 to be coated consisting of a soft-steel sheet is chemically converted, and the surface is brush-coated with an adhesive medium such as ethylene glycol monobutyl ether in a desired pattern to form a substrate film 2. A powder paint 3 is then applied to form a coating film in a specified thickness without impressing an electrostatic voltage, and the applied powder paint 3 is sucked with the suction nozzle 4 of a vacuum cleaner. Consequently, the powder paint on the substrate film 2 remains as such by the adhesion of the substrate. The powder paint on the part not coated with the substrate film 2 is sucked and removed, and a desired pattern is formed as a protrusion 5. The protrusion 5 is irradiated with IR and melted, and a protruding film 6 is formed.

However, recently, it has been said that the use of a solvent type paint which discharges an organic solvent which causes air pollution in connection with environmental problems is not preferable, and the film thickness obtained by one coating is a solvent type paint. 4 to 5μ for paint
Since it is possible to make the thickness as thick as 0 to 150 μm, attention has been paid to powder coatings capable of forming a high-grade appearance finish and a tough protective film that is hard to be scratched. The powder coating material is a composition containing powder such as resin as a constituent component and is applied to an object to be coated. The coating method is such that each particle of the powder coating material is charged and An object to be coated, such as a plate or the like, is grounded, powder is attached to the surface of the object by electrostatic attraction, and then baked to form a film. There are widely known and well-known methods such as a sprinkling method of spraying a powder coating on the surface, and a fluidized dipping method of putting a preheated object in the spray of powder coating rising from a fluidized bed for coating. There is. Such powder coatings
It is used in many metal baking coating fields in place of solvent-based paints.For example, epoxy resin powder coatings are used for electrical insulation coatings, outer coatings of buried steel pipes, metal furniture, and acrylic resins. BACKGROUND ART Powder coatings based on polyester and polyester resins are used for exterior coatings of household electric appliances and for coating gates, fences, and the like. Recently, coating with powder paint
For example, in the field of cosmetics such as electric refrigerators, metal furniture, building materials, etc.
Three-dimensional patterns, multicolor patterns, and precision printed patterns are required to increase added value.

In the case of coating with a powder coating, it is easy to form a transparent or monochromatic coating film on the entire surface of an object to be coated, but when a transparent or monochromatic pattern is formed or multicolor coating is performed. For example, as described in JP-A-5-104056, in a method of electrostatically coating a powder coating material using a masking material and removing the masking material before baking, the above-mentioned masking material is used. In the method in which the paint adheres to the surrounding coating film and the masking material is removed after baking, the coating material applied on the masking material becomes integral with the surrounding coating film, making it difficult to remove the masking material. However, if it is attempted to remove it forcibly, the surrounding coating film will be peeled off, and in each case, a sharp edge pattern cannot be obtained, and there is a problem that the boundary line cannot be clearly painted. Therefore, when a sharp edge pattern is to be formed, it is said that it is convenient to apply a solvent-based paint which is less problematic. It should be noted that the same publication also describes a method of applying a powder coating material, scraping off an unnecessary portion of the powder coating material with a rubber spatula, and baking the remaining coating material to form a pattern. The edge portion of the coating film that remains when scraping with a spatula or the like rises, and in this case too, a sharp edge pattern cannot be obtained.

In the present invention, the object to be coated means a metal base material, a wood base material, concrete, a casting, a ceramic product,
It is possible to use a porous substrate such as a paper product or any other substrate which can be coated with powder coating material such as coating by electrostatic coating or spraying, which will be described later. Forming a three-dimensional surface on the surface of the object to be coated means forming an uneven surface, and the purpose thereof is not only decoration but also any other purpose such as increasing the surface strength. The surface of the object to be coated may be the surface of the material itself, but it may be the surface that has already been coated, and this coating is not limited to powder coating, but may be solvent coating. Also, in the case of a porous material such as a wood base material, sealing with a sealer, polishing with sandpaper, etc., so-called blanking, followed by application of an intermediate coating paint to make the surface smooth preferable. As the sealer and the intermediate coating, a lacquer type used as a woodworking coating, an aminoalkyd clear type, a urethane type, a polyester type or the like can be used, but for low temperature curing, work efficiency, etc., an ultraviolet curing type coating or Electron beam curable paints are preferred. UV-curable coating materials include polyester-based, urethane-based, epoxy-based, polyether-based, acrylic-based oligomers,
Monovinyl-based, divinyl-based, trivinyl-based, tetravinyl-based, etc. reactive diluents and acetophenone, benzoin ether-based, benzyl ketal-based, and those obtained by blending a ketone-based photopolymerization initiator, and the like. It is more preferable that the coating film is resistant to heating during the formation of the powder coating film and that does not release volatile components such as solvents and monomers from the coating film during heating.

In the present invention, the adhesive medium having adhesiveness means a medium which is applied to the surface of the object to be coated and has adhesiveness, and it may be a fluid or a powder. Having adhesiveness mainly means adhering the powder coating to the surface of the object to be coated, and the liquid includes liquid, and the adhesiveness of the coating layer causes the powder coating to adhere to the surface of the object to be coated. However, in the case of powder, it is necessary that the adhesive property is produced by, for example, heating, application of a solvent or the like after being applied to the surface of the object to be coated. The fluid may be a melt such as a resin or an oligomer. This adhesiveness needs to be at least some time before the powder coating material is attached to the object to be coated and the powder coating material that does not pass through another attachment medium is removed, but it may be permanent. When this adhesion medium dissolves the powder coating material well, when the adhesion medium is, for example, a solvent, bubbles are generated in the coating film due to the heat of the subsequent baking step, like the solvent type coating material. When the generation is not preferable, an adhesion medium having low solubility is preferable, and a non-dissolving medium for powder coating is more preferable. However, it can be used in that case because it has some solubility and in some cases the powder coating can adhere well to the surface of the article to be coated. In the present invention, “not having solubility” includes not only the case of non-solubility but also the case of having a little solubility but close to non-solubility.

From these facts, a high boiling point solvent can be mentioned as an adhering medium which is a liquid at room temperature and atmospheric pressure, but its solubility in the powder coating material differs depending on the powder coating material used. The boiling point may be lower than or higher than the baking temperature of the powder coating material, or higher, but the latter case is preferable in that the adhesive force can be maintained until the baking. As the boiling point of the solvent, for example, since powder coating is usually baked at 130 ° C or higher, a low-volatile solvent having a vapor pressure of 5 mmHg or lower at 150 ° C or higher and 170 ° C or higher is preferable. Glycol monobutyl ether (boiling point 1
71 ° C.), ethylene glycol dibutyl ether (boiling point 201 ° C.), propylene glycol monobutyl ether acetate (boiling point 192 ° C.) and other glycol ethers, isophorone (boiling point 214 ° C.) and other ketones, Solvesso 150 (Exxon Chemical Co. product) And other organic solvents such as hydrocarbon-based solvents such as cyclohexanol, alcohol-based solvents such as cyclohexanol, and ketone / alcohol-based solvents such as diacetone alcohol. These may be used alone or as a mixture, and other similar boiling points and vapors may be used. It can also be used in admixture with pressure solvents and other solvents with different boiling points and vapor pressures. The mixing and use in this way are from the viewpoint of adjusting the solubility of the powder coating material, the ease of wetting the surface of the object to be coated, adjusting the volatility, non-combustibility, cost and the like. When a liquid is used as the attachment medium, the powder coating applied is not attached to the surface of the object to be coated, but rises from the gap of the powder coating particles to the upper layer due to the capillary phenomenon due to the surface tension,
Since the particles are strongly bonded to each other, thick film coating can be performed, and when removing the excess powder coating material, the end face of the pattern can be held and a sharp edge can be obtained. At this time, the powder coating material may be pressurized to exude the solvent or may be heated.

A viscous liquid is more effective as an adhesion medium, and if this is done, the amount of solvent applied to the surface of the object to be coated will also increase, so the adhesion of the applied powder coating material. The amount to be applied increases, and a thick film coating film having a thickness of more than 300μ can be formed. Examples of the viscous liquid include ethylene glycol (boiling point 197 ° C.).
In addition, any kind of high boiling point may be used,
If it is compatible with the powder coating, it may change the gloss of the coating film or may impair the physical properties of the coating film, and therefore it is preferable that the coating composition is not compatible. In the present invention, the adhesion medium is also preferably a high-boiling point solvent that does not dissolve the powder coating material and has a boiling point higher than the melting point of the powder coating material. It is also preferred that the solvent is an organic solvent.

As the adhesion medium which exhibits fluidity when heated, a hot melt type adhesive may be mentioned, and specifically, an ethylenically unsaturated compound such as an ethylene vinyl acetate copolymer and vinyl acetate or further Examples thereof include compounds obtained by copolymerizing other unsaturated compounds, rosin, and rosin derivatives, and these may be used alone or as a mixture with a solvent and other additives. In this case, if the same hot-melt adhesive as the resin component of the powder coating material is used, it may be well compatible with the powder coating material and may be preferable in terms of adhesiveness and the like.
