Description

Technical Field

[0001] The present invention relates to decorative papers and decorative boards, and a method for manufacturing decorative papers and decorative boards.

Background Art

[0002] Conventionally, there has been a decorative board in which a thermosetting resin such as a melamine resin is impregnated into a decorative paper and the impregnated thermosetting resin is cured. Such a decorative board has a high surface hardness and is excellent in stain resistance, abrasion resistance, heat resistance, water resistance, etc., and is therefore used as a surface material for furniture such as desks and as a surface material for fixtures such as store counters. In addition, in order to impart a visual three-dimensional effect to the surfaces of decorative papers and decorative boards, there are decorative papers and decorative boards in which the gloss of the resin layer on the surface is adjusted with a matting agent or the like.

[0003] As a decorative paper with gloss adjustment and a decorative board in which the decorative paper is impregnated with a resin, there are a decorative paper for a resin-impregnated decorative board and a resin-impregnated decorative board described in Patent Document 1. The decorative paper for a resin-impregnated decorative board and the resin-impregnated decorative board described in Patent Document 1 include a base paper, a pattern layer formed by printing a pattern on the base paper, and a liquid-repellent cured film provided on the pattern layer. The liquid-repellent cured film is composed of a first liquid-repellent cured film covering the entire pattern layer and a second liquid-repellent cured film provided on a part of the first liquid-repellent cured film. The first liquid-repellent cured film and the second liquid-repellent cured film have different glossinesses to realize a design with gloss adjustment.

[0004] However, in the decorative paper for a resin-impregnated decorative board and the resin-impregnated decorative board described in Patent Document 1, since the liquid-repellent cured film penetrates into the base paper, a desired design with gloss adjustment cannot be obtained, and there is a risk of poor designability.

[0005] The decorative sheet described in Patent Document 2 and the decorative board provided with the decorative sheet include a decorative layer provided on a paper base material, a release layer provided on the decorative layer and formed in synchronization with a region where a low gloss of a pattern of the decorative layer is desired, and a surface layer formed in a region adjacent to the release layer and having a high gloss. The decorative sheet described in Patent Document 2 and the decorative board provided with the decorative sheet achieve a design with gloss adjustment by having a difference in gloss between the release layer and the surface layer. The surface layer is formed of a melamine resin impregnated into the decorative sheet and cured.

[0006] The decorative sheet described in Patent Document 2 and the decorative board provided with the decorative sheet have a coating layer between the surface layer and the release layer and the decorative layer.

Modes for Carrying Out the Invention

[0021] An embodiment of the present invention will be described with reference to the drawings.

[0022] FIG. 1 is a cross-sectional view schematically showing the configuration of the decorative paper 10 according to the present embodiment. FIG. 2 is a cross-sectional view schematically showing the configuration of the decorative board 100 according to the present embodiment.

[0023] In the present embodiment, as shown in FIGS. 1 and 2, the thickness direction of the decorative paper 10 and the decorative board 100 is defined as the "vertical direction V", the side where the base ply 1 of the decorative paper 10 is provided is defined as the "lower side LO" in the vertical direction V, and the side opposite to the lower side LO is defined as the "upper side UP" in the vertical direction V.

[0024] The decorative board 100 includes a decorative paper 10 and an impregnated resin 5. The decorative board 100 is formed by impregnating the decorative paper 10 with the impregnated resin 5 and curing the impregnated resin 5 that has been impregnated.

[0025] By impregnating the decorative paper 10 with the impregnated resin 5, the impregnated resin 5 penetrates into the interior of the decorative paper 10. The impregnated resin 5 that has penetrated into the interior of the decorative paper 10 cures covering the surface of the decorative paper 10 as shown in Fig. 2. The decorative board 100 impregnated with the impregnated resin 5 and cured has excellent properties such as high surface hardness, solvent resistance, stain resistance, abrasion resistance, heat resistance and water resistance.

[0026] The impregnated resin 5 is a known thermosetting resin used for resin-impregnated decorative boards. As the impregnated resin 5, a melamine resin, an epoxy resin, a diallyl phthalate resin, a benzoguanamine resin, a urethane resin, an alkyd resin, an unsaturated polyester resin, a phenolic resin or a urea resin, etc. can be adopted.

[0027] The impregnated resin 5 is impregnated into the decorative paper 10 as an aqueous impregnating liquid dissolved or dispersed in water. As the impregnated resin 5, it is preferable to adopt a melamine resin having high strength and excellent solvent resistance, stain resistance, abrasion resistance, heat resistance and water resistance.

[0028] The decorative paper 10 includes a base layer 1, a pattern printing layer 2, a high-design protection layer 3, and a high-design resin layer 4.

[0029] The base layer 1 is a layer provided on the lower side LO of the decorative paper 10. The base layer 1 is a known fibrous sheet that can be impregnated with the impregnated resin 5. As the base layer 1, for example, titanium paper, tissue paper, fine paper, unbleached kraft paper or bleached kraft paper, etc. can be adopted.

[0030] As the base layer 1, it is preferable to adopt titanium paper having excellent printing suitability and resin impregnation suitability. There is no restriction on the thickness of the base layer 1. Generally, those with a basis weight of 20 g / m 2 or more and 200 g / m 2 or less are used.

[0031] The pattern printing layer 2 is a layer provided on the upper side UP of the base material layer 1, and is formed by performing printing such as wood grain, stone grain, or sand grain. As a printing method for the pattern printing layer 2, known printing methods such as gravure printing, offset printing, flexographic printing, silk screen printing, or inkjet printing can be adopted.

[0032] For the pattern printing layer 2, known printing inks suitable for the adopted printing method can be adopted. It is preferable to adopt water-based ink for the pattern printing layer 2. Since water-based ink is more compatible with the aqueous solution of the impregnating resin 5 compared to oil-based ink, when impregnating the decorative paper 10 with the impregnating resin 5, it can be impregnated quickly and uniformly, and further, it can have excellent strength by integrating with the impregnating resin 5.

[0033] As the water-based ink adopted for the pattern printing layer 2, it is preferable to adopt an ink whose binder resin is mainly casein or emulsion resin. Since the binder resin mainly composed of casein or emulsion resin has the property of becoming water-insoluble after going through a drying process after printing the ink, in the process of impregnating with the impregnating resin 5, it is difficult to redissolve in the aqueous solution of the impregnating resin 5, suppressing the damage of the pattern on the pattern printing layer 2, and suppressing the contamination of the impregnating resin 5 to the dissolved pattern printing layer 2.

[0034] As the emulsion resin contained in the binder resin, for example, acrylic-based, vinyl acetate-based, styrene-based, urethane-based, etc. can be adopted. As the binder resin, for the purpose of improving the stability of the ink, for example, a combination of water-soluble resins such as polyvinyl alcohol or polyacrylamide, water-soluble polymers such as polysaccharides or cellulose derivatives, etc. may be adopted.

[0035] The high-design protection layer 3 is a layer provided on the upper side UP of the pattern printing layer 2. As shown in FIG. 1, the high-design protection layer 3 is partially provided on the upper side UP of the pattern printing layer 2. The coating amount of the high-design protection layer 3 is 1.0 g / m 2 or more and 5.0 g / m 2 or less. Here, the coating amount indicates the dry coating amount.

[0036] It is preferable to adopt a transparent or translucent material for the high-design protection layer 3 to such an extent that the pattern of the pattern printing layer 2 can be seen through. The material of the high-design protection layer 3 is not limited, but it is preferable to adopt a thermosetting resin. Examples of the resin used for the high-design protection layer 3 include casein resin and urethane resin.

[0037] As a method for forming the high-design protection layer 3, known printing methods such as gravure printing, offset printing, flexographic printing, silk screen printing, or inkjet printing can be adopted. Also, the high-design protection layer 3 may be formed using a known coating device.

[0038] The high-design resin layer 4 is a layer provided on the upper side UP of the high-design protection layer 3. The coating amount of the high-design resin layer 4 is 0.5 g / m 2 or more and 3.0 g / m 2 or less. Here, the coating amount indicates the dry coating amount.

[0039] The high-design resin layer 4 is provided at a position synchronized with the high-design protection layer 3. The high-design resin layer 4 is preferably provided at a position synchronized with the pattern of the pattern printing layer 2. In that case, the high-design protection layer 3 and the high-design resin layer 4 are provided at positions synchronized with the pattern of the pattern printing layer 2.

[0040] It is preferable to adopt a transparent or translucent material for the high-design resin layer 4 to such an extent that the pattern of the pattern printing layer 2 can be seen through the high-design protection layer 3. As the high-design resin layer 4, a thermosetting resin, an ionizing radiation-curable resin, an ultraviolet-curable resin, or a mixture thereof can be adopted.

[0041] As the high - design resin layer 4, for example, thermosetting resins such as melamine - based resins, epoxy - based resins, urea - based resins, phenol - based resins, unsaturated polyester - based resins, diallyl phthalate - based resins, benzoguanamine - based resins, urethane - based resins, aminoalkyd - based resins, silicone - based resins, etc., or ionization radiation - curable resins such as (meth)acrylate - based resins, unsaturated polyester - based resins, etc. can be adopted. It is preferable to add a release agent for the purpose of excluding the impregnating resin 5 to the high - design resin layer 4.

[0042] As a method for forming the high - design resin layer 4, known printing methods such as gravure printing, offset printing, flexographic printing, silk - screen printing, or ink - jet printing can be adopted. Also, the high - design resin layer 4 may be formed using a known coating device.

[0043] The coating area of the high - design protective layer 3 is preferably 0.5 times or more and 1.5 times or less with respect to the coating area of the high - design resin layer 4. The coating area refers to the area in a plan view as seen from the upper side UP in the decorative paper 10.

[0044] Not all of the resin forming the high - design resin layer 4 needs to be disposed on the upper side UP of the high - design protective layer 3. It is sufficient that at least a part of the resin forming the high - design resin layer 4 is provided on the upper side UP of the high - design protective layer 3.

[0045] For example, when the coating area of the high - design protective layer 3 is smaller than the coating area of the high - design resin layer 4, a part of the high - design resin layer 4 is disposed on the upper side UP surface of the pattern printing layer 2.

[0046] The gloss of the high - design resin layer 4 may be adjusted to impart a gloss - matte design to the decorative paper 10 and the decorative board 100. For example, by adding a matting agent (mat agent) to the high - design resin layer 4, the gloss can be adjusted, and a gloss - matte design can be imparted to the decorative paper 10 and the decorative board 100.

[0047] By adding a matting agent to the high-design resin layer 4, the gloss of the high-design resin layer 4 can be lowered and adjusted to a desired gloss. By adjusting the gloss of the high-design resin layer 4, a difference can be created between the gloss of the portion where the high-design resin layer 4 is provided and the gloss of the portion where the high-design resin layer 4 is not provided in the decorative paper 10 and the decorative board 100. Due to this gloss difference, it is possible to visually create a three-dimensional feeling by utilizing the illusion of the human eye.

[0048] As the matting agent added to the high-design resin layer 4, for example, fine particles composed of inorganic substances such as silica, alumina (such as α-alumina), calcium carbonate, barium sulfate, kaolinite, aluminosilicate, and organic substances such as polycarbonate, nylon, urethane resin, acrylic resin, styrene resin, silicone resin, etc. can be adopted.

[0049] The average particle diameter of such a matting agent is preferably about 1 to 30 μm, and the addition amount of the matting agent can be appropriately selected according to the desired gloss (matte property).

[0050] Also, a three-dimensional feeling due to touch can be imparted to the decorative paper 10 and the decorative board 100 by the thickness in the vertical direction V of the high-design protective layer 3 and the high-design resin layer 4. For example, when the pattern of the pattern printing layer 2 is wood grain and the high-design protective layer 3 and the high-design resin layer 4 are provided above the conduit portion of the wood grain (UP), a three-dimensional feeling due to touch can be imparted to the conduit portion of the wood grain by the thickness in the vertical direction V of the high-design protective layer 3 and the high-design resin layer 4.

[0051] By realizing a three-dimensional feeling due to vision and a three-dimensional feeling due to touch by the high-design protective layer 3 and the high-design resin layer 4, the decorative paper 10 and the decorative board 100 can have an excellent design.

[0052] Since the high-design resin layer 4 is provided above the high-design protective layer 3 (UP), it is difficult to penetrate into the base material layer 1. That is, the high-design protective layer 3 has a caulking effect of suppressing the penetration of the high-design resin layer 4 into the base material layer 1.

[0053] Since the high-design protection layer 3 has a caulking effect, it is possible to suppress a decrease in the area of the high-design resin layer 4 formed on the upper side UP of the high-design protection layer 3 from becoming smaller than the desired area due to seepage, and to suppress a decrease in design quality.

[0054] The coating amount of the high-design protection layer 3 is 1.0 g / m 2 or more and 5.0 g / m 2 or less, and the coating amount of the high-design resin layer 4 is 0.5 g / m 2 or more and 3.0 g / m 2 or less, by which it is possible to achieve both sufficient impregnation properties of the impregnating resin 5 with respect to the decorative paper 10 and excellent design quality by the high-design protection layer 3 and the high-design resin layer 4.

[0055] Also, the coating amount of the high-design protection layer 3 is 1.0 g / m 2 or more and 5.0 g / m 2 or less, and the coating amount of the high-design resin layer 4 is 0.5 g / m 2 or more and 3.0 g / m 2 or less, by which it is possible to suppress variations in the penetration of the high-design resin layer 4 into the base fabric layer 1 and to realize the decorative paper 10 and the decorative board 100 having sufficient design stability.

[0056] Next, a method for manufacturing the decorative paper 10 and the decorative board 100 will be described. FIG. 3 is a flowchart showing an example of a process for manufacturing the decorative paper 10 and the decorative board 100 by a decorative board manufacturing system. Here, the decorative board manufacturing system is a system that executes the manufacture of the decorative paper 10 and the decorative board 100.

[0057] (Step S1) First, the decorative board manufacturing system performs step S1 (pattern printing process). In step S1, a pattern is printed on the upper side UP of the base fabric layer 1 to form a pattern printing layer 2.

[0058] (Step S2) Next, the decorative board manufacturing system performs step S2 (protective layer printing process). In step S2, a high-design protective layer 3 is formed on the upper side UP of the pattern printing layer 2. At this time, the high-design protective layer 3 is partially formed on the upper side UP of the pattern printing layer 2. Also, the coating amount of the high-design protective layer 3 is 1.0 g / m 2 or more and 5.0 g / m 2 or less.

[0059] (Step S3) Next, the decorative board manufacturing system performs step S3 (surface resin layer printing process). In step S3, a high-design resin layer 4 is formed on the upper side UP of the high-design protective layer 3 to obtain the decorative paper 10. At this time, the high-design resin layer 4 is provided at a position synchronized with the high-design protective layer 3. Also, the coating amount of the high-design resin layer 4 is 0.5 g / m 2 or more and 3.0 g / m 2 or less.

[0060] (Step S4) Next, the decorative board manufacturing system performs step S4 (resin impregnation process). In step S4, the impregnating resin 5 is impregnated into the decorative paper 10 obtained in step S3.

[0061] In step S4, the impregnating resin 5 may be impregnated from the upper side UP of the decorative paper 10, or may be impregnated from the lower side LO. Also, it may be impregnated in multiple times from the upper side UP or the lower side LO, or may be impregnated simultaneously from the upper side UP and the lower side LO.

[0062] (Step S5) Next, the decorative board manufacturing system performs step S5 (pressing process). In step S5, the decorative paper 10 impregnated with the impregnating resin 5 in step S4 is sandwiched from the upper side UP and the lower side LO by a press plate such as a metal plate, and the decorative paper 10 is pressed and heated from the upper side UP and the lower side LO.

[0063] By pressing and heating the decorative paper 10 impregnated with the impregnating resin 5, the thermosetting resin forming the impregnating resin 5 hardens, and the decorative board 100 is formed. As a method of heating and pressing the decorative paper 10, a method of pressing flat by contacting a metal plate, a circular pressure continuous lamination method, or the like can be adopted.

[0064] According to the decorative paper 10 and the decorative board 100 of the present embodiment, it includes a base material layer 1, a pattern printing layer 2 provided on the upper side UP of the base material layer 1, a high-design protection layer 3 partially provided on the upper side UP of the pattern printing layer 2, and a high-design resin layer 4 provided on the upper side UP of the high-design protection layer 3 in synchronization with the high-design protection layer 3.

[0065] The coating amount of the high-design protection layer 3 is 1.0 g / m 2 or more and 5.0 g / m 2 or less. The coating amount of the high-design resin layer 4 is 0.5 g / m 2 or more and 3.0 g / m 2 or less.

[0066] The decorative paper 10 and the decorative board 100 have excellent design properties because the high-design protection layer 3 suppresses the penetration of the high-design resin layer 4 into the base material layer 1. Also, since the high-design protection layer 3 does not inhibit the impregnation of the impregnating resin 5 into the decorative paper 10, the decorative paper 10 and the decorative board 100 have excellent impregnation properties.

[0067] As a result, it is possible to provide a decorative paper 10 and a decorative board 100 with excellent design properties and impregnation properties, and a method for manufacturing the decorative paper 10 and the decorative board 100.

[0068] As described above, one embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and design changes and the like within the scope not departing from the gist of the present invention are also included. Also, the components shown in the above-described one embodiment and the modification examples shown below can be configured by appropriately combining them.

[0069] (Modification Example 1) In the above embodiment, the decorative board 100 includes the decorative paper 10 and the impregnated resin 5, but the form of the decorative board is not limited thereto. The decorative board may include a core paper or a base material on the lower side LO of the decorative paper 10.

[0070] As the core paper laminated on the lower side LO of the decorative paper 10, for example, titanium paper, bleached kraft paper, unbleached kraft paper, glass fiber non-woven fabric, etc. can be adopted. Also, a core paper impregnated with a thermosetting resin may be laminated on the lower side LO of the decorative paper 10 and then pressed and heated.

[0071] As the thermosetting resin to be impregnated into the core paper, for example, melamine resin, epoxy resin, diallyl phthalate resin, benzoguanamine resin, urethane resin, alkyd resin, unsaturated polyester resin, phenolic resin, urea resin, etc. can be adopted.

[0072] As the base material laminated on the lower side LO of the decorative paper 10, a wood-based material such as particle board or medium density fiberboard (MDF), a metal plate-like member such as aluminum or stainless steel, a composite board in which a metal such as aluminum is attached to both sides of a core material made of a resin such as polyethylene, etc. can be adopted.

[0073] When laminating a core paper or a base material on the lower side LO of the decorative paper 10, it may be laminated via an adhesive. By laminating a core paper or a base material on the lower side LO of the decorative paper 10 to form a decorative board, any functions such as improvement of rigidity and adjustment of thickness can be imparted to the decorative board.

[0074] The present invention will be described in detail with the following examples. The present invention is not limited to the following examples.

[0075] (Example 1) As the original layer 1, titanium paper with a basis weight of 80 g / m 2 was prepared.

That is, five decorative boards using the decorative papers of Examples 1-7 and Comparative Examples 1-10 were prepared respectively.

[0098] In the design stability evaluation test, in Examples 1-7 and Comparative Examples 1-10, a sensory test was carried out on five decorative boards by 10 testers, and the evaluation was made focusing on the appearance rate at which the gloss on the surface of the decorative board changed partially and selectively.

[0099] The evaluation criteria were divided into three levels, and ○ was regarded as passing. 〇 (Good): Seven or more people evaluated that the design stability was good. △ (Fair): Five or more and six or less people evaluated that the design stability was good. × (Poor): Four or less people evaluated that the design stability was good.

[0100] (Test 3) The impregnation property evaluation test was carried out on the decorative papers of Examples 1-7 and Comparative Examples 1-10. In the impregnation property evaluation test, for the decorative paper cut into a 5 cm square, with the side where the high-design resin layer was laminated facing down, it was floated on the liquid melamine resin, and the time taken for the melamine resin to penetrate the entire surface of the side where the base fabric layer was laminated was evaluated.

[0101] The evaluation criteria were divided into three levels, and ○ was regarded as passing. 〇 (Good): 20 seconds or less. △ (Fair): 21 seconds or more and 30 seconds or less. × (Poor): 31 seconds or more.

[0102] (Test Results) The results of Tests 1-3 are shown in Table 1. Table 1 also shows the comprehensive evaluation results of comprehensively evaluating the results of Tests 1-3 for the cosmetic papers of Examples 1-7 and Comparative Examples 1-10. The evaluation criteria for the comprehensive evaluation were three levels: ○ (Good), △ (Fair), and × (Poor), and ○ was considered passing.
