Description

The present invention relates to a coating material sample board using a novel base material.

Conventionally, when selecting and confirming the design and color tone of architectural finishing materials, a sample book or sample board made by painting the coating material actually used has been created and shown to the orderer, owner, etc. It was. In Chapter 15 “15.1.3 Sample” of “Public Building Construction Standard Specification (Building Construction) 2004 edition” which is a non-patent document, it is described that a sample book or a sample coated plate is used. Only. In addition, in the section of finish coating material finishing “15.5.3 Construction in general” in section 5 of this document, there is a description that the sample coating plate can be checked for the required amount or coating thickness for each confirmation process. As described above, in the specification or other patent documents, no reference was made to the material of the sample coating plate.

In the actual market, sample books with a plurality of patterns and colors are mainly made by pasting painted materials on paper. As sample plates, asbestos slate plates and MDF plates are used. (Medium fiberboard) and plywood were often used. Asbestos slate board, one of the materials of the sample board, is prohibited from using asbestos due to health problems, and the flexible board that obtains the specified strength is thicker than that containing asbestos, so it is easy to carry and store. In addition, in the case of plywood and MDF board, from the viewpoint of effective utilization of natural resources, the base material of the sample board that is coated directly on the substrate and discarded after use is used. It was a waste of resources to use a ˜6 mm plate only once.

In this invention, it replaces with the board | substrate material of the sample board conventionally utilized, and it is going to provide the form suitable for the use of only a coating film part suitable for recycling, using a new material further. .

The gist of the coating material sample plate according to claim 1 of the present invention is that it is composed of a coating material layer, an underlayer and a substrate.

Further, the gist of the coating material sample plate according to claim 2 is that the base layer and the coating material layer are configured to be easily peeled in the invention according to claim 1.

In the coating material sample plate according to claim 3, in the invention according to claim 1, the base layer is composed of a peelable sheet, and a part or all of the coating material layer and the base layer from the peeling position can be separated. It is the summary.

In the coating material sample plate according to claim 4, in the invention according to any one of claims 1 to 3, the underlayer has a hygroscopic property on the coating material layer side, and does not transmit in the middle or the substrate side. The gist is to have a conductive film.

The gist sample board according to claim 5 is characterized in that, in the invention according to any one of claims 1 to 4, the substrate is a multi-hole rigid board.

Since the sample board mount described in claim 6 is used for the coating material sample board described in any one of claims 1 to 5, it is composed of an underlayer and a substrate.

Hereinafter, the constituent elements of the present invention will be described in order.
The coating material layer said to this invention means the part only of the coating film by the finish coating material of a sample coating board. Finish coating materials are JIS A6909: 2003, thin finish coating materials, thick finish coating materials, lightweight finishing coating materials, multi-layer finishing coating materials, or flexible finishing finishing coating materials specified in architectural finishing coating materials. In addition, it is a layer composed of a coating that is used for finish coating with a design or material not specified in JIS. Therefore, it includes all of the cases from a case where it is composed of only one type of finishing coating material to a case where it is composed of a plurality of finishing coating materials such as an undercoat, a main material and a top coating material.

According to the present invention, the base layer is a portion that becomes the base of the coating material layer, which absorbs the moisture or solvent of the finish coating material and restricts or prevents the moisture and solvent of the coating material from permeating to the substrate. Say.

As the material used for this underlayer, coated printing paper including non-coated printing paper, lightweight coated paper, coated paper, art paper (for example, mirror coat: trade name of Oji Paper, Picasso coat: product of Daio Paper) Name, Esprit Coat: Nippon Paper Industries), high quality paper, medium quality paper, lower grade paper, unbleached kraft paper, bleached kraft paper, special paperboard, Manila ball, coated ball, cast coat, craft ball paper, paperboard Or paper, water-resistant and oil-resistant paper processed from paperboard, synthetic paper, plastic board, plywood, and aluminum board are exemplified, and among them, the surface (side contacting the coating material layer) is hygroscopic and the back side is not water permeable. Preferably used. However, as a result of moisture absorption, a material having difficulty in water resistance is not good because it swells and the base swells or the coating material layer coated thereon has problems such as swell and cracks.

When plastics such as polyethylene and polypropylene are used as they are for the underlayer or when oil-resistant and water-resistant paper is used, it is not preferable because sufficient adhesion with the coating material layer cannot be obtained. Similarly, when high quality paper is used, the substrate and the base layer are peeled off due to water absorption, which is not preferable. In addition, when an aluminum plate is used, the raw material is expensive, and it is not preferable because it takes time and labor for separation when it is recycled.

Furthermore, the underlayer preferably has a hygroscopic property on the coating material layer side, and has an impermeable film on the middle or substrate side. By constructing in this way, when creating the coating material sample, the ground can absorb the moisture or solvent in the coating material, the coating material can be soaked into the ground, and an anchoring effect can be obtained, and It is possible to prevent moisture or solvent from permeating to the substrate side. By preventing the moisture or solvent from permeating, adverse effects on the substrate or the adhesive that bonds the substrate and the underlayer can be prevented. As a material having such a function, a paperboard that has been subjected to moisture-proofing or laminating is preferably used.

For the substrate of the present invention, the same material as that of the underlayer can be used. Paperboard, plastic board, plywood and aluminum board can be used. Above all, when it is made of a laminate of paperboard, it is lightweight and it is easy to obtain the required strength, and it can be used efficiently when separating the coating material layer and underlayer and using it for recycled paper. is there. Other materials have the inconvenience that it takes time to reuse and recover resources after separating the coating material layer or the coating material layer and the base layer.

As a means for reducing the weight of the substrate, it is preferable to make a hole in the substrate to make a multi-hole rigid plate. The multi-hole rigid plate is a plate in which a large number of holes are regularly opened. Various shapes such as circles, ellipses, triangles, squares, pentagons, hexagons, stars, etc. can be adopted as the shape of the hole, but it is easy to set up, easy to manufacture the device, and move the device. From the viewpoint of the amount of power for this, a circular hole is desirable.

The arrangement and quantity of the holes are set within a range in which the coating material layer is formed on the substrate and the strength to prevent bending is ensured. Usually, it is economical to set the hole size in the range of 3 to 50 mm. If it is 3 mm or less, the labor for perforation becomes large and the efficiency of weight reduction becomes worse. In the case of 50 mm or more, it is difficult to set the position of the hole with respect to the coating material sample plate, and the strength of the substrate is reduced, which is not good. The number of holes is determined by the arrangement on the substrate, and the distance between the holes is preferably in the range of 1 to 10 mm. When the size of the hole is small, there is no problem in strength even with a small value, and when it is large, it is necessary to increase the interval in order to ensure the strength of the substrate. In addition, it is easy to design the hole arrangement at the lattice point position. However, as a staggered position, all the circular holes can be equidistant.

The multi-hole rigid plate provided with holes is 50% to 70% of the weight of the flat plate without holes. When a multi-hole rigid board made of 4 mm thick laminated paperboard was created, the weight before drilling was 230 g in terms of A4 plate equivalent, and 145 g when holes with a diameter of 15.5 mm were opened at intervals of 4 mm. It was. Similarly, A4 plate equivalent weight is comparable to plywood (5.5mm thickness) 185g, MDF board (medium fiber board, 4.0mm thickness) 204g, asbestos slate board (4.0mm thickness) 406g. Thus, the burden on the person who manufactures and uses the sample plate can be reduced.

In this invention, the coating material sample board is not used only for design and color tone selection and confirmation, but can be easily stored after confirmation of a part of the sample board, or a sample board mount. We are also trying to make it easier to recycle.

One of them is that the base layer and the coating material layer can be easily peeled off. By comprising in this way, it becomes possible to store a coating material sample by making only a coating material layer independent. When storing as a coating material sample, a part of the sample plate area, if not all, can be cut out and stored. In order to make it easy to peel, an easily peelable surface can be obtained by applying silicone coating on the surface or laminating a resin film such as polyethylene or polypropylene.

  If comprised in this way, in reusing a board | substrate and a base layer, isolation | separation with a coating material will become easy, and it will become easy to prevent mixing of the pigment, filler, and binder which are the main components of a coating material.

Another method is that the base layer is composed of a sheet that can be peeled off. Since the base layer is peelable, a part of the coating material layer and the base layer is separated from the peeling position, and a coating film sample in which a part of the base layer is integrated is obtained. As for the peeling position, if the base layer is a laminated surface of the base layer or the base layer is a laminate, and an easy peeling surface is formed between the layers, a part or all of the coating material layer and the base layer can be separated from the substrate.

The separation of only the coating material layer, which is the invention of claim 2 described above, breaks the coating material layer unless the coating material layer has toughness or elasticity, but the underlayer is separated together. If so, the possibility is small.

In order for the underlayer to be delaminated, the underlayer is achieved by performing papermaking a plurality of times. Further, when the papermaking itself has a thickness of about 0.5 mm, the subsequent delamination can be easily performed.

As for the case where a part of the coating material layer and the base layer is separated, similarly to the previous example, the storage of the coating material sample can be facilitated, and the reuse of the substrate and the base layer can be facilitated. .

According to the first aspect of the present invention, the separation and collection after use as a coating material sample plate can be facilitated by having the base layer.

In the invention of claim 2, in addition to the effect of the invention of claim 1, after being used as a coating material sample plate, a sample of only the coating material can be stored, or a separated substrate and underlayer can be reused. Making it easy.

In the invention of claim 3, in addition to the effect of the invention of claim 1, there is a part or all of the underlayer even if the sample of the coating material is not separable only by the method of claim 2. Thus, it is possible to obtain a thin sample in which only a necessary portion of the coating material sample is stored in a light weight.

According to the invention of claim 4, in addition to the effects of the invention of any one of claims 1 to 3, the base layer is excellent in adhesion to the coating material layer and does not adversely affect the substrate or the bonded portion of the substrate and the base layer. be able to.

In the invention of claim 5, in addition to the effects of the invention of any one of claims 1 to 4, the substrate is reduced in weight while ensuring the necessary strength.

In the invention of claim 6, since the effect of the invention of any one of claims 1 to 5 can be obtained, an optimum substrate and underlayer without problems as a coating material sample plate are provided.

Examples of the present invention will be shown and described in detail below.

In the embodiment, the multi-hole rigid plate as the substrate 1 is bonded with five sheets of non-coated paper having a basis weight of 460 g / square meter and further bonded with 450 to 480 g / square meter of coated paper on both sides. The thing of thickness 4mm when match | combining was utilized. This substrate has a size of 42.5 cm × 23.6 cm, and is regularly provided with 20 circular holes 4 in the long side direction and 11 circular holes 4 in the short side direction. The maximum hole size is 16mm and the minimum is 14mm. This is caused by the angle of the cutting edge of the punch when drilling holes in paperboard. A taber is attached to make it easy to remove the punched parts after the holes have been drilled. It is also a thing. The apparent basis weight in this multi-hole state was 2260 g / square meter.

For the underlayer, cast coated paper having a continuous amount of 210 kg is used in Example 1, and press-coated paper having a continuous amount of 180 kg is used for non-coated paper in Example 2, and an acrylic ester copolymer is used for the substrate. It was bonded together with an adhesive consisting of The base used in Example 2 used a surface drawn with vinyl on the substrate side, and was able to absorb moisture in the coating material on the side where the coating material was applied.

The coating material layer was coated with a coating material of a multi-layer finishing coating material defined in JIS A6909 “Finishing coating material for construction” over three steps. The products used were an undercoat “Kikusui Primer Super E”, a main material coating “Kikusui Tile Emaruna”, and a top coat “Ultra Dry” manufactured by Kikusui Chemical Co., Ltd.
