Description

A panel for furniture with improved durability, and an edge processing method for it

The present invention relates to a panel for furniture with improved durability, a method and a processing apparatus for processing the same therefor, and provides a processing method for forming an edge with enhanced unity on the edge of a panel for furniture, and also efficiently processing the same It relates to a processing device for automation that can do this.

Wood is widely used in furniture and architectural interiors. However, if raw wood is used as it is, the wood grain is alive and eco-friendly, but deformation may occur due to contraction and expansion depending on temperature and humidity, and there is a limit to its use due to its high price. Therefore, furniture panels using PB or MDF instead of solid wood are widely used. PB is compressed at high temperature and high pressure by mixing adhesive with wood shavings, and MDF is compressed in the same way using finer wood particles than PB. However, since the outer surface of MDF and PB is not smooth, a separate finishing material must be attached to the outer surface. In addition, there is a method of bonding a band-shaped edge band made by extruding plastic materials such as PVC, PP, ABS resin, and PMMA (acrylic resin) to the edge using an adhesive, but there is a gap between the edge of the edge and the wood. Contamination of foreign substances is easy, and moisture is easy to penetrate, so peeling of the edge occurs a lot.

Alternatively, there is a method of forming an edge on the edge of the furniture panel 10 by mounting a furniture panel to form the edge finishing layer inside the mold, filling the edge with a thermosetting resin or urethane resin through an injection machine, and foaming and curing it. However, when thermosetting resins such as unsaturated polyester are used, they are easily sharply broken by impact, which may cause safety problems. Since this is a necessary system, there is a problem in that the cost is excessively generated. In the case of urethane foam, it is difficult to express the various aesthetic senses of the product because the colors are simple, such as black and gray. The urethane edge part and the joint part of the middle panel are not clean, so it is not aesthetically beautiful. In addition, the urethane foamed edge is a soft, semi-rigid material, and has a disadvantage in that it cannot be used for a long time due to its weak durability when using a plate material.

Accordingly, the inventors of the present invention have focused on a frame finishing material and a finishing method capable of improving moisture resistance and durability between the wood panel provided between the upper finishing material and the lower finishing material, and the edge finishing material.

The furniture panel 10 of the present invention,

An intermediate panel 11 used as a base of the furniture panel 10 is provided, and an upper surface finishing material 12 and a lower surface finishing material 13 are adhered to both surfaces of the intermediate panel 11 . Since the adhesive used between the intermediate panel 11, the upper surface finishing material 12, and the lower surface finishing material 13 contains harmful components such as carcinogens, the edge and the upper surface of the intermediate panel 11 to prevent the adhesive component from leaking. It is required to form a sealing rim finishing layer 14 so as not to form a gap between the finishing material 12 and the lower surface finishing material 13 . In this case, in order to maintain durability even for a long period of time, it is preferable to select a material for finishing the edges that can be tightly sealed. In general, for the intermediate panel 11, particle board (PB), medium-density fibrous wood (MDF), other honeycomb boards, and plywood with a thickness of 3mm to 30mm are suitable for the intermediate panel 11, and the upper surface finishing material 12 and the lower surface finishing material 13 are intermediate panels. It can have various thicknesses depending on the type of (11).

The upper surface finishing material 12 and the lower surface finishing material 13 are respectively attached to the upper surface and the lower surface of the intermediate panel 11 with an adhesive to make the appearance of the intermediate panel beautiful. The size of the top finishing material and the bottom finishing material can be exactly the same as the size of the middle panel to match the edges, but as in the embodiment of FIG. It can be configured, and in particular, it can be bonded so that the cross-section is U-shaped.

A gel finishing material is spray-coated on the edge formed by the upper surface finishing material 12, the lower surface finishing material 13, and the intermediate panel 11 to form the edge finishing layer 14, but is formed integrally with the edge. The gel finishing material is spray applied to the edge of the intermediate panel, and the nozzle for spraying the gel finishing material is moved in an up-and-down arc shape in a state that is spaced apart from the edge of the intermediate panel by a predetermined interval. By applying the gel finishing material, the edge finishing layer (14) may be formed in a semi-circle or semi-ellipse shape on the edge of the intermediate panel.

The upper surface finishing material 12 and the lower surface finishing material 13 may be in the form of a film having a thickness of usually less than 1 mm or a sheet having a thickness slightly thicker than 1 mm. Since the upper surface finishing material or the lower surface finishing material is approximately 0.1 to 30 mm larger in all directions than the size of the intermediate panel 11, the rim can form a U-shape. By doing so, the gel finishing material sprayed between the top finishing material 12 and the bottom finishing material 13 is evenly applied to form the edge finishing layer 14 while the top finishing material 12, the bottom finishing material 13, and the middle panel ( 11) will be formed integrally with the frame. At this time, the edge does not necessarily have to be a C-shape, and it is sufficient if the upper surface finishing material 12 and the lower surface finishing material 13 can wrap the intermediate panel 11 from above and below.

On the other hand, the gel finishing material forming the edge finishing layer 14,

Preferably, a gel finishing material obtained by mixing at least one of cork powder and coffee powder with an acrylic resin base is used. The gel finishing material for the edge finishing layer 14 is applied to the edge of the furniture panel by spraying it with a spray nozzle 410 . The spray-applied acrylic resin base has elasticity even after drying, and the flame resistance is strengthened by allowing the coffee powder or cork powder to be mixed. In addition, other powders may be used. For example, coffee silver skin powder, copper powder, mulberry bark powder, mulberry bark cod powder, natural soil powder, stone powder, wood powder, grain powder, inorganic powder, Korean paper powder, waste paper powder, glass fiber powder, glass fiber powder , glass powder, carbon powder or lacquer powder. In addition, coffee powder or cork powder can be dyed to a desired color after decolorization using an oxidative bleach and fluorescent dye if necessary according to the purpose of the product.

As a preferred embodiment, with respect to 100 phr (parts per hundred rubber) of the acrylic base resin, 1 to 300 phr of powder, 1 to 100 phr of curing agent, 10 to 20 phr of pigment, 1 to 10 phr of additives such as antibacterial agent, fragrance, flame retardant, fluorescent pigment, and photoluminescent pigment to form a gel finishing material.

In addition, the intermediate panel 11 is a commonly used wood compression panel, PB, MDF. Since wood compression panels are made by compressing wood chips together with an adhesive, the adhesive components are exposed through the edges and the appearance of the edges is not beautiful. and the carbonized edge of the middle panel has a luxurious appearance. Therefore, even if the edge finishing layer 14 is separated after long use, it is possible to prevent the rim of the carbonized intermediate panel 11 from revealing the unsightly appearance of the intermediate panel 11 as it is. Alternatively, the intermediate panel 11 may be formed of a honeycomb board, and coffee foil may be filled in the inner space of the honeycomb board to have an upcycling and antibacterial effect.
