Description

Edge strip for furniture panel for imparting matte effect to PET substrate and method for manufacturing the same

[0001] The present invention relates to an edge strip for use on the edge of a furniture panel, and more specifically, to an edge strip for a furniture panel that implements a matte effect on a PET fabric (substrate) and a method for manufacturing the same.

[0002] For most wooden furniture, the edges of furniture panels such as particleboard or MDF (medium density fiberboard) are finished with edge strips.

[0003] The edge strip is largely composed of ABS (acrylonitrile butadiene styrene) resin, a transfer paper with an arbitrary pattern printed on one side of the ABS resin, and a primer applied to the opposite side of the ABS resin to increase adhesion.

[0004] And the transfer paper is composed of OPP (biaxially oriented polypropylene) or PET (polyethylene terephthalate) substrate, release agent, UV-curable paint, printing layer, and hot melt adhesive in that order, and all of these have a thickness of approximately 0.03 mm, making it a very thin structure.

[0005] Edge strips come in glossy, semi-matte, and matte finishes. Over time, edge strips can become scratched and fingerprints and other foreign substances can become lodged on their surface, resulting in an unsightly appearance. Therefore, matte finishes are often preferred. To produce matte finishes, an OPP substrate must be used instead of a PET substrate. This is because, with a PET substrate, only glossy or semi-matte finishes can be achieved, while only an OPP substrate can produce matte finishes.

[0006] Therefore, in order to manufacture a matte edge strip, only an OPP substrate must be used, but the problem is that when manufacturing a matte edge strip using an OPP substrate, the OPP substrate is weak to heat, so the OPP substrate melts at the transfer temperature (200°C) and deforms the substrate, and also, when heat of 200°C is applied, the OPP substrate sticks to the roller, reducing workability, and when the temperature is lowered to prevent the OPP substrate from sticking to the roller, the hot melt does not melt, so transfer does not occur.

[0007] Therefore, there is a need for a matte edge strip for use on the edge of furniture panels using PET substrate.

[0008] The present invention has been made in consideration of the above circumstances, and the problem to be solved is to provide a matte edge strip used for the edge portion of a furniture panel using a PET substrate and a method for manufacturing the same.

[0009] As a result of researching the above problem, the inventor of the present invention discovered that the above problem could be solved by making a specific configuration, and thus completed the present invention.

[0010] That is, the gist of the present invention is,

[0011] A method for manufacturing an edge strip for a furniture panel comprising a printing layer transfer paper, ABS resin, and a primer,

[0012] The above printed layer transfer paper,

[0013] A step (S1) of obtaining a matte PET substrate by coating a mixture of urethane, methyl ethyl ketone (MEK), and calcium carbonate (calcium carbonate) twice at a speed of 80 to 100 m / min on a gravure printer, then maintaining the mixture in a curing room at 75 to 85°C for 6 to 7 days and coating a release agent;

[0014] Step (S2) of coating the matte coated PET substrate obtained above with a mixture of a water-based urethane curing agent and water (weight ratio 100:50) at a speed of 40 to 45 m / min to a dry thickness of 1.5 to 2 ㎛; and

[0015] A method for manufacturing an edge strip for a furniture panel is provided, including a step (S3) of coating the PET substrate coated above with a UV-curable paint, treating it with an oil-based ink, and then applying an adhesive (hot melt) to print to form a printed layer.

[0016] A preferred embodiment of the present invention provides a method for manufacturing an edge strip for a furniture panel, wherein, in the step (S1), the weight ratio of urethane, methyl ethyl ketone, and calcium carbonate is 17 to 19: 5 to 7: 4 to 6, and the particle size of the calcium carbonate is 10 to 20 ㎛.

[0017] Another preferred embodiment of the present invention provides a method for manufacturing an edge strip for a furniture panel, characterized in that the above step (S1) is performed twice.

[0018] Another preferred embodiment of the present invention provides a method for manufacturing an edge strip for a furniture panel, characterized in that the step (S2) is sequentially performed at 140°C, 135°C, 110°C, 105°C, and 60°C.

[0019] The edge strip for furniture panels manufactured by the present invention can prevent damage to the appearance caused by foreign substances such as scratches and fingerprints formed on the surface.

[0020] Figure 1 is a cross-sectional view of the configuration of an edge strip for a furniture panel according to the present invention.

[0021] Figure 2 is a cross-sectional view of a printed layer transfer paper among the edge strips for furniture panels according to the present invention.

[0022] Hereinafter, the present invention will be described in detail with reference to the attached drawings. However, this description does not limit the present invention.

[0023] As illustrated in Fig. 1, the edge strip (10) for a furniture panel is largely composed of a printing layer transfer paper (1), ABS resin (2), and a primer (3). Since this is a widely known structure, its specific composition and manufacturing method are omitted.

[0024] The printing layer transfer paper (1), which is the core technology of the present invention, is composed of a hot melt (1a), a printing layer (1b), a UV-curable paint (1c), a release agent (1d), and a PET substrate (1e), as shown in Fig. 2.

[0025] The edge strip (10) for conventional furniture panels has a glossy or semi-matte printing layer transfer paper (1), but in the present invention, a method for manufacturing a matte printing layer transfer paper (1) that has never been used before is specifically described.

[0026] The method for manufacturing a printed layer transfer paper (1) according to the present invention is as follows:

[0027] A step (S1) of obtaining a matte PET substrate (1e) by coating a mixture of urethane, methyl ethyl ketone (MEK), and calcium carbonate twice at a speed of 80 to 100 m / min on a gravure printer, then maintaining the mixture in a curing room at 75 to 85°C for 6 to 7 days and coating a release agent (1d) of 10 μm;

[0028] Step (S2) of coating the matte coated PET substrate (1e) obtained above with a mixture of a water-based urethane curing agent and water (weight ratio 100:50) at a speed of 40 to 45 m / min to a dry thickness of 1.5 to 2 ㎛; and

[0029] It includes a step (S3) of coating the PET substrate (1e) coated above with a UV-curable paint (1c), treating it with an oil-based ink, and then applying an adhesive (hot melt) (1a) to print to form a printed layer (1b).

[0030] In the above step (S1), first, a mixture of urethane, methyl ethyl ketone (MEK), and calcium carbonate is coated twice on a semi-matte PET substrate (1e) in a gravure printer at a speed of 80 to 100 m / min. Here, if the coating speed is less than 80 m / min, there is a problem that haze occurs on the coating surface, and if the coating speed exceeds 100 m / min, there is a problem that the coating is not sufficiently dried.

[0031] At this time, the coating temperature must be maintained in a curing room at 75 to 85°C for 6 to 7 days. If the coating temperature in the curing room is below 75°C, there is a problem of the PET substrate not being cured, and if it exceeds 85°C, there is a problem of wrinkling.

[0032] Next, a release agent (1d) is coated to obtain a matte PET substrate (1e) having fine irregularities formed on the surface. Acrylic is one of the release agents used in the present invention.

[0033] Then, the matte coated PET substrate (1e) obtained above should be coated with a mixture of a water-based urethane curing agent and water (weight ratio 100:50) at a speed of 40 to 45 m / min to a dry thickness of 1.5 to 2 ㎛ (step S2).

[0034] Next, the matte PET substrate (1e) coated above is coated with a UV-curable paint (1c), then treated with oil-based ink, and then an adhesive (hot melt) (1a) is applied and printed to form a printed layer (1b) (step S3).

[0035] Acrylic is an example of a UV-curable paint used in the present invention.

[0036] In a preferred embodiment of the present invention, in the step (S1), the weight ratio of urethane, methyl ethyl ketone, and calcium carbonate is 17 to 19: 5 to 7: 4 to 6. If this range is exceeded, there is a problem in that the surface is not flat during the work process. At this time, the particle size of the calcium carbonate should be 10 to 20 ㎛. If the particle size of the calcium carbonate is less than 10 ㎛, micro-unevenness is not formed, and if the particle size of the calcium carbonate exceeds 20 ㎛, printing is not performed well.

[0037] In one embodiment of the present invention, it is preferable to perform the above step (S1) twice. This is because the surface coating is stably formed.

[0038] In another preferred embodiment of the present invention, the step (S2) is performed five times while sequentially lowering the temperature to 140°C, 135°C, 110°C, 105°C, and 60°C. This is because the surface coating is stably formed.

[0039] Example

[0040] Hereinafter, a method for manufacturing an edge strip for a furniture panel according to the present invention will be described by way of example.

[0041] In a gravure printer, a mixture of urethane, methyl ethyl ketone (MEK), and calcium carbonate (particle size 15 ㎛) (weight ratio 18:6:5) was coated twice at a speed of 100 m / min on a semi-matte PET substrate (length 660 mm x width 19 mm), and then maintained in a curing room at 85°C for 7 days, and urethane was coated as a release agent to obtain a matte PET substrate.

[0042] The matte coated PET substrate obtained above was sequentially coated 5 times at 140°C, 135°C, 110°C, 105°C, and 60°C with a mixture of a water-based urethane curing agent and water (weight ratio 100:50) at a speed of 45 m / min to a dry thickness of 2 μm.

[0043] The resulting coated PET substrate was coated with 10 g of D100 (manufactured by Burim Chemical Co., Ltd.) as a UV-curable paint, then treated with 10 g of gravure ink (manufactured by Burim Chemical Co., Ltd.) as an oil-based ink, and then 10 g of ABS 320 (manufactured by Sungbo Ink Co., Ltd.) as an adhesive was applied and printed to form a printed layer, thereby obtaining a printed layer transfer paper.

[0044] The printed layer transfer paper obtained above was placed on one side of the ABS resin, pressed against a roller, and then 10 g of Rakoll (manufactured by HB Fuller) was applied as a primer to the opposite side to manufacture an edge strip for a furniture panel intended for the present invention.

[0045] Above, although the preferred embodiments of the present invention have been described in detail, the present invention is not limited to the above embodiments, and various modifications are possible by a person having ordinary knowledge in the art within the scope of the technical idea of ​​the present invention.
