The present invention relates to a method for decorating the surface of a building base material, and particularly to a method for forming a beautiful decorative surface with excellent wear resistance and heat resistance on the surface of a building base material such as concrete, board, or slate. Conventional methods for applying decoration to the surface of building materials are broadly divided into flooring, typified by vinyl chloride tiles and vinyl chloride floors, and flooring, which involves coating with urethane resin, synthetic rubber, or the like. PVC tiles are inexpensive and are used in large quantities as flooring materials, but because they lack durability, their use has been limited to offices, schools, etc. where durability is not particularly required. In addition, PVC tiles tend to collect dust in their joints, so
It cannot be used in places where cleanliness is required, such as hospitals. Vinyl chloride floors have become rapidly used in recent years due to their excellent design and functionality, as well as ease of installation, but they lack water resistance, heat resistance, and durability. . On the other hand, painted floors made of urethane resin or synthetic rubber are so durable that they are even used in gymnasiums, etc., but they cannot be decorated with patterns. Due to its lack of design, its uses are still limited. Considering the above points, several methods have already been proposed for applying patterns to painted floors to improve design, but each method has difficulties in terms of workability, pattern reproducibility, freedom, etc., and has not been put into practical use. There are still limits. For example, immediately after forming an uncured resin coating on the surface of a building base material, colored flakes with a thickness of 0.1 to 0.5 mm and an area of 1 to 100 mm2 are sprinkled, and the colored flakes are allowed to adhere to the base resin and harden. There are ways to form patterns. However, this method requires an overcoat to fix the flakes to the base, and also requires sanding to correct warping of the flakes. A method is also known in which colored granules are mixed with a transparent resin coating material and spread on the surface of the substrate to create a colored granular pattern. A sophisticated technique is required to mix uniformly, and furthermore, it is difficult to develop a reproducible pattern on the surface of the substrate because particulate matter settles or floats after the coating is formed. Next, there is a method of spreading a resin film forming material onto a base material and spraying different colored thixotropic resins on it before curing to form a pattern, but this method produces a pattern with a rich variety like a marble pattern. I can't do it. On the other hand, if two or more types of resin coating film-forming materials with different colors are coarsely mixed and then cast onto the surface of the substrate and cured, it is possible to obtain extremely varied patterns; There is a problem with reproducibility. Further, according to a method in which a resin coating film-forming material is spread and cured on a base material, and then a pattern is printed or painted, a pattern rich in variation can be obtained with good reproducibility.
The pattern easily disappears due to wear, and there is no way to repair it, so it is not practical. The present invention has been made in order to solve the various problems described above in methods for decorating the surface of building base materials, and provides beautiful, wear-resistant, heat-resistant, and deep patterns on the surface of building base materials. The purpose is to provide a makeup method that can give a pattern. The method of decorating the surface of a building base material according to the present invention involves applying a one-component urethane resin to the surface of the building base material to form an undercoat resin layer, and before this undercoat resin layer is completely cured, a colored two-component urethane resin is applied to the surface of the building base material. A polyurethane resin is applied to form an intermediate coating resin layer, and then, before this intermediate coating resin layer is completely cured, an impregnated film on which a pattern has been applied in advance is laid in close contact with the intermediate coating resin layer. Next, a urethane resin is applied to impregnate the impregnated film with the resin and an impregnated resin layer is formed, and before this impregnated resin layer is completely cured, a two-component urethane resin is applied to form an elastic protective layer. It is characterized by forming a protective layer on the surface by applying a one-component urethane resin. The present invention will be explained in detail below based on the drawings. First, as shown in FIG.
An undercoat resin layer 2 is formed thereon. The purpose of the undercoat resin layer 2 is to provide adhesiveness between the base material surface 1 and the intermediate coat resin layer 3, and to prevent exudation of substances from the base material, such as alkaline substances in the case of a concrete base material. A moisture-curable one-component urethane resin is generally used as the undercoat resin. In addition to concrete, which is a typical base material, it has excellent adhesion to various materials such as plastic and wood, so it is suitable. The undercoat resin may be colored in advance using a suitable toner. Before this undercoat resin layer 2 is completely cured, a colored intermediate coat resin is applied thereon. The intermediate coating resin layer 3 eliminates irregularities on the surface 1 of the building base material to form a smooth surface, sufficiently hides the color tone peculiar to the building base material, and further provides cushioning properties as necessary. 0.1~20mm, preferably 0.5~
Preferably it has a thickness of 5 mm. A two-component urethane resin is used as such an intermediate coating resin. The coloring of the intermediate coating resin is appropriately selected depending on the pattern and color tone to be applied, and may be transparent or translucent in order to give depth to the pattern. Next, before the intermediate coating resin layer 3 is completely cured, an impregnated film 5 having a picture pattern 4 is laid on the intermediate coating resin layer 3. This impregnable film 5
Alternatively, the sheet is a nonwoven fabric, paper, etc. that is transparent itself or becomes substantially transparent when impregnated with a resin, and the pattern 4 is previously applied thereon. As will be described later, this impregnable film 5 is laid on the intermediate resin layer 3 and impregnated with resin, so that
It is necessary to not be attacked by the impregnating resin or its diluting solvent, and to have air permeability so that air bubbles between the intermediate coating resin layer and the film can be easily defoamed during impregnation, and to be easily impregnated. Further, when a rotary printing press is used to apply a pattern onto an impregnated film, it is necessary to have appropriate mechanical strength and ink transferability. Therefore, in the present invention, a nonwoven fabric made of rayon, polyester, urethane, glass, etc. and having a weight of about 15 to 100 g/m 2 , preferably about 25 to 50 g/m 2 is preferably used. When using paper as the impregnable film, for example, so-called transparent paper that does not contain titanium oxide is preferably used in order to give depth to the pattern after application. The appropriate basis weight is 20 to 150 g/m 2 , preferably 30 to 80 g/m 2 . As the so-called impregnated film with a pattern, for example, woven fabrics of natural fibers such as cotton and linen, synthetic fibers such as rayon, nylon, and polyester, and mineral fibers such as glass fiber and asbestos can be used. , foamed sheets can also be used. The pattern 4 is usually applied to the impregnated film 5 by gravure printing, but other conventional printing methods such as offset printing, letterpress printing, and silk screen printing are also used to print in a single color or in multiple colors. If it is difficult to print on the impregnated film 5 or if printing is inappropriate, transfer onto the impregnated film using a transfer paper on which a so-called pattern has been applied in advance. You can also do it. In this case, a heat seal layer made of a thermoplastic resin may be provided on the surface resin layer of the transfer paper. The impregnable film 5 as described above is laid in contact with the intermediate resin layer 3 described above and impregnated with the resin. The surface of the impregnated film with a pattern may be brought into contact with the intermediate coating resin layer, or the surface without a pattern may be brought into contact with the intermediate coating resin layer. When using an impregnated film with a pattern applied by a transfer method, it is preferable to bring the surface with the pattern into contact with the intermediate resin layer. During impregnation, air bubbles between the impregnable film 5 and the intermediate coating resin layer 3 are sufficiently defoamed, and the film is brought into close contact with the intermediate coating resin layer. Therefore, the impregnating resin is required to have low viscosity, easy air bubble movement, long pot life, no skin formation on the impregnated resin surface, and low solvent content to suppress the generation of air bubbles. However, it is desirable to use a two-component urethane resin that satisfies these requirements. The impregnating resin is usually applied at a rate of 50 to 500 g/m 2 , preferably 100 to 300 g/m 2 . Since the impregnated film 5 is impregnated and embedded in the resin layer 6 in this way, the ink that forms the pattern on the impregnated film needs to have strong adhesion to both the impregnated film and the impregnated resin. It is. Therefore, when a urethane resin is used as the impregnating resin, a polyol is preferable as the ink vehicle. Polyisocyanate is not suitable for use because it reacts with moisture in the air and gels, which may cause printing defects. Specific examples of polyols used as vehicles include polyvinyl chloride having a hydroxyl group at the end, acrylic resin, polyvinyl acetate, polyester resin, and copolymers of these, and these may be used alone or in a mixture of two or more. used as. The adhesion strength between the impregnated resin layer 6 and the ink is determined by selecting the hydroxyl equivalent of these vehicles,
Alternatively, it can be adjusted by selecting the mixing ratio of polyol and non-polyol. Next, a transparent top coat resin layer 7 is formed on the impregnated resin layer 6 before the impregnated resin is completely cured. This top coat resin layer 7 is composed of an elastic protective layer 8 in contact with the impregnated resin layer 6 and a surface protective layer 9 in contact with this elastic protective layer. In detail, the elastic protective layer 8 is formed by applying a two-component urethane resin in the same manner as the intermediate resin layer 3, and is made of a material that provides appropriate elasticity to the decorative surface but does not cause yellowing. is desirable. The thickness of the elastic protective layer 8 is appropriately selected depending on the required physical properties. A one-component moisture-curing urethane resin is applied onto the elastic protective layer 8 to form a surface protective layer 9. The one-component moisture-curing urethane resin has sufficient abrasion resistance to protect the surface, heat resistance that does not cause thermal deformation or discoloration even when exposed to cigarette smoke, and the adhesiveness of the elastic protective layer 8. If erasing is desired, esbon processing can be performed before the surface protective layer 9 is completely cured. Esbon processing is carried out, for example, by using an embossing roll on the semi-cured resin surface having thixotropy, by using a spray method, or by removing the chips after curing the surface protective layer in the presence of chips. be able to. Cosmetics that have design or fashion properties are generally required to be reapplicable. In the present invention, at least one release layer may be provided between the undercoat resin layer and the surface protective layer. This release layer refers to a layer in which the adhesiveness between this layer and other layers is minimized compared to that between any other layers. This release layer may be newly provided between the undercoat resin layer and the surface protective layer,
Alternatively, any layer between the undercoat resin layer and the surface protective layer may also serve as this release layer. A specific example of providing a release layer is shown in FIG. 2, for example. this is,
A release layer 1 is provided between the intermediate coating resin layer 3 and the impregnated resin layer 6.
As shown in FIG. 3, the layer above the impregnated resin layer 6 containing the impregnated film 5 can be peeled off from the intermediate resin layer and reapplied. The material forming the release layer 10 is preferably a resin material that inhibits the adhesion between the intermediate coating resin layer and the impregnated resin layer, and when the intermediate coating resin and the impregnating resin are urethane resins as described above, The resin material for forming the release layer 10 is a mixture of urethane resin and acrylic resin or nitrocellulose resin. In the present invention, "complete hardening of the resin" refers to a state in which the adhesiveness of the resin surface disappears and the resin to be applied next can be sufficiently adhered to the resin without any special surface treatment. According to the present invention, as described above, an impregnable film on which an arbitrary picture pattern is printed or transferred is laid on the surface of the building base material coated with an intermediate coating after undercoating, impregnated with resin, and then transparent film is applied on top of this. By forming an overcoat resin layer, the above-mentioned pattern can be made beautiful and clear, and
It can be made to appear on the surface of the base material with glass-like depth. In particular, since a one-component urethane resin is used for the undercoat resin layer, it has good adhesion to the building base material and has excellent water resistance and alkali resistance against moisture and alkaline substances exuding from concrete. In addition, since a two-component urethane resin is used for the intermediate coating resin layer, and a one-component or two-component urethane resin is used for the impregnated resin layer and the elastic protective layer, it has good cushioning properties, a large optical refractive index, and high transparency. It's so good that the pattern looks beautiful. Furthermore, since a one-component urethane resin is used as the surface protective layer, it has excellent abrasion resistance, heat resistance, and chemical resistance. Furthermore, each layer uses urethane resin, and the next resin is applied on top of the applied layer before it is completely cured, so there are no boundaries between each layer, making it possible to create a durable makeup. . Further, according to the present invention, an impregnated film with a picture pattern applied in advance is laid down and then urethane resin is applied to impregnate the film with the resin, so that the film is integrated with the surrounding resin and the picture pattern is formed. Not only is it clearly visible, but the film elastically deforms together with the resin layer when a load is applied to the floor surface due to walking, etc., so the cushioning properties when walking are not impaired. Therefore, the cosmetic method of the present invention is rich in design and fashion, and is suitable for public buildings, hospitals, department stores,
Suitable for decorating concrete surfaces such as gymnasiums and other surfaces. EXAMPLES The present invention will be explained in more detail with reference to Examples below. In the examples, all "parts" indicate "parts by weight." Example 1 40 parts of polyvinyl chloride, 10 parts of acrylic resin, 45 parts of polyvinyl chloride having a hydroxyl group equivalent to 0.5 g, and 5 parts of urethane plasticizer were added to 40 g/m 2 of polyester nonwoven fabric (Japan Vilene Co., Ltd., H8104). An impregnated film was created by printing a wood grain pattern with an ink using the mixture as a vehicle.

PC5500 mixed at a weight ratio of 1:1) at a coating amount of 2Kg/m 2
(thickness: 1.6 mm). Furthermore, after 14 hours, the impregnated film was placed on the semi-cured two-component resin layer with the pattern side facing up, and one-component urethane resin (Takeda Pharmaceutical Co., Ltd.,
Takenate M605N and ethyl acetate in a weight ratio of 3:1
(mixed in ) was cast and impregnated with a roll while carefully defoaming. After 3 hours, a transparent two-component urethane resin (Takenate Pharmaceutical Co., Ltd., Takenate F134 and Takerac MPKA in a weight ratio of 7.5:4) was added as an elastic protective layer.
After 14 hours, a one-component urethane resin (Takenate M605N, Takeda Pharmaceutical Co., Ltd.) was applied as an elastic protective layer at a coating amount of 0.05 kg/m 2 to eliminate surface stickiness. It was applied by spraying to give a weight of Kg/ m2 . The thus obtained decorative surface exhibits a beautiful wood grain pattern, has practically sufficient abrasion resistance and heat resistance, and has an appearance and physical properties suitable for use as a flooring material for a gymnasium, for example. Example 2 A solid layer made of 100 parts of polyamide resin was provided on thin paper 23 g/m 2 (Sanko Paper Co., Ltd.) by gravure printing, and a marble pattern was printed on this using the same ink as in Example 1, A transfer paper was prepared by providing a solid layer using a thermoplastic urethane resin as a vehicle as a heat-sealing layer. Using this transfer paper, 30g/
roll heat transfer (150 °C, 10
Kg/m 2 , 2m/min) to prepare an impregnated film. When this film was used to apply decoration to a concrete surface in exactly the same manner as in Example 1, a decorative surface with clear pattern density and good resin impregnation was obtained. Example 3 0.3g on white transparent paper 50g/m 2 (Kojin Co., Ltd., OLP)
A decorative sheet was prepared by grapia printing a tile pattern using an ink containing 75 parts of polyvinyl chloride having an equivalent amount of hydroxyl groups and 25 parts of acrylic resin as a vehicle. Using this decorative sheet, decoration was applied to a concrete surface in the same manner as in Example 1 to obtain a beautiful decorative surface. The cosmetic stains were almost the same as those with conventional painted floors. Example 4 A one-component urethane resin (Takenate XF100, Takeda Pharmaceutical Co., Ltd.) was applied as an undercoat resin layer on the mortar-finished floor surface using a roller bucket at a coating amount of 0.1 kg/m 2 . It was dried for 5 hours. Next, two-component urethane resin (Takeda Pharmaceutical Co., Ltd., Takenate F4-332 colored)
was applied at 2 kg/m 2 to erase the irregularities on the base mortar surface, and at the same time form an elastic intermediate coating layer with an average thickness of about 1.5 mm. A decorative sheet with wood grain printing produced by the method of Example 1 was placed on top of this intermediate coating layer so that the printed surface was the top surface. From this top surface, apply a xylene-ethyl acetate solution (Takenate XF350, Takeda Pharmaceutical Company Limited) of a non-yellowing polyurethane polyisocyanate consisting of xylylene diisocyanate, trimethylolpropane, and polyethylene adipate at a rate of 200 g/m 2 using an impregnating roller. Using a roller or the like, it was adhered evenly without wrinkles or air bubbles. After 6 hours have passed after applying this impregnated adhesive, a topcoat layer is applied on top of the non-yellowing polyurethane brepolymer (Takeda Pharmaceutical Co., Ltd. Co., Ltd., Takenate XF400A) and trimethylolpropane,
Mixed polyol of polypropylene ether glycol and polytetramethylene ether glycol (Takenate XF400B, Takeda Pharmaceutical Company Limited)
were mixed at a weight ratio of A/B = 55/30, and applied at a rate of 1 kg/m 2 using a metal trowel so that the surface was smooth and uniform in thickness. After 20 hours of application, the topcoat layer remained clear and colorless, and the wood grain pattern was clearly emphasized. This decorative surface shows no discoloration, no change in gloss, and no change in sheet properties even after long-term outdoor exposure tests.
It has extremely high durability, and along with the other benefits of urethane, it has performance suitable for general flooring. Example 5 When applying decoration to the surface of a building base material made of plywood using the decorative sheet printed by the method of Example 3, the following method was used to enable re-application. The intermediate coating resin used in Example 4 (Takenate XF200A, B, Takeda Pharmaceutical Co., Ltd.) was mixed with 12 parts of acrylic resin and applied. The other steps were performed in the same manner as in Example 4. After all the resins were completely cured, a sample was cut from the treated floor surface and the adhesive strength between each layer was measured. The results are shown in Table 1.
