Description

TECHNICAL FIELD [0001] The present invention relates to a shoe box having a multi-layer resin sheet panel bonded with a composite panel,

The present invention relates to a shoe box to which a composite panel of a stone having a multi-layered resin sheet panel is bonded by using a method of manufacturing a composite composite panel of a stone. More particularly, Layered resin sheet panel having a thickness of 0.2 mm to 2 mm is manufactured by sequentially laminating the resin sheet having a multi-layer structure intersecting in a zigzag form so that the structure of the resin sheet is perpendicular to the upper and lower sides, By adhering to one side of a stone with a predetermined thickness using an adhesive, the stone can be horizontally cut and processed into a stone plate having a thickness of 1 mm to 3 mm, so that the exposed surface exposed to the outside is made of a stone plate It is excellent in lightness and durability while also faithfully expressing the original aesthetic of stone, and is excellent in flexibility and processing robustness. It is used for furniture, door, ceiling material, A multi-layered resin sheet panel-bonded stone composite using a manufacturing method of a stone composite panel manufactured to be used as various interior materials such as a decorative panel for interior, exterior and interior of a building, a desk, a desk lamp, a lighting lamp, a refrigerator door, To a shoe box with a panel attached thereto.

Recently, as interest in the residential environment has increased, there has been an increasing use of eco-friendly building stone as an interior and exterior material of a building.

Here, stone is a generic term of a raw material of a rock or a civil engineering and building material obtained by its processing.

The stone is easy to see from the surroundings, but it has a natural beauty and deep beauty. It is well suited to any place and has a unique beauty that does not bother over time.

Moreover, although the stone types are various, the texture of each stone is wide and the choice is wide.

For example, many kinds of marble such as granite, serpentinite, andesite, tuff, diorite, gabbro, slate, etc. have been actively used as interior materials for interior and exterior as well as marble widely used from the past.

In particular, natural marble, artificial marble and granite are widely used as interior and exterior materials for buildings.

As described above, such a stone is a highly desirable building material which not only exposes the building with high quality, but also has durability and is capable of maintaining the quality for a long time and does not emit harmful substances to the human body.

However, these stones are difficult to be collected and processed, and accordingly, they are not widely used because they are formed at a high price.

In particular, it is difficult to process a conventional stone in the form of a panel having a thickness less than a certain thickness due to an impact accompanied by a cutting process, and even if a thin panel form is obtained, it is likely to be broken easily.

In addition, there is a problem that economical efficiency and workability are deteriorated due to excessive weight at the time of construction. As a result, when natural stone such as marble is used as interior and exterior materials for construction, there is a problem that construction costs are incurred in addition to the cost of marble itself.

In order to solve such a problem, a method has been developed in which a stone such as marble has been cut to a predetermined thickness and the cut stone plate is adhered to a general synthetic resin panel.

In other words, a technique for providing a stone panel that is lightweight and improved in construction efficiency while securing economic efficiency by thinning stone is being researched and developed.

For example, Korean Patent Laid-Open Publication No. 2013-24456 (published on March 3, 2013) discloses a technique for implementing a composite door using marble in which a marble panel having a certain thickness is bonded to a honeycomb structure core made of a hollow structure At this time, it is suggested that the thickness of the marble is about 5 mm or so.

In addition, Korean Patent Registration No. 1244095 (published on Mar. 31, 2013) discloses a honeycomb panel having a profile structure and a stone composite panel equipped with the honeycomb panel. In this case, the stone is composed of a honeycomb panel and a profile structure It is proposed to finish the surface finishing work and the side finishing work by thinly putting it in a state of being attached to the surface of 1 mm to 10 mm.

As described above, the honeycomb structural cores (or honeycomb panels) are bonded to one side of the thin marble plate material to ensure sufficient rigidity while reducing weight, so that loading and transporting is easy, And a method for expecting the effect that facilitates the work is suggested.

However, in the above-mentioned prior arts, a method of thinly cutting marble (or stone) is not described in detail, but is exemplarily described only as being thinly cut to a level of 1 mm to 10 mm.

On the other hand, as described above, there have been many difficulties in manufacturing the stone panel by the conventional technique. In other words, it was very difficult to produce a thick stone panel (eg natural marble) on a primary basis, cut the produced stone panel to produce a panel with a certain thickness, and then adhere to a synthetic resin panel.

Particularly, when the stone panel is cut, when the panel thickness is thin, the panel is broken or the periphery of the panel is broken, and various research and development are continuing to solve the problem.

The following prior art documents can be found from the prior art regarding a method for thinly cutting a stone panel.

That is, Korean Patent Registration No. 1228982 (published on Feb. 15, 2013) discloses a technique relating to a stone panel, a manufacturing method thereof, and a door panel using the stone panel. In the stone panel manufacturing method disclosed in the above- As shown in Fig. 1, (a) preparing a plate-like stone; (b) attaching a stiffener to at least one side of the stone; (c) horizontally cutting the stone into at least two slices; (d) removing the reinforcing material to obtain a stoneportion having a predetermined thickness; (e) at least one reinforcing plate made of a synthetic resin material having a melting point of 200 DEG C or higher is passed through a plurality of holes aligned in the longitudinal direction so as to have a regular cell structure of polygonal or circular in cross section perpendicular to each longitudinal direction ; (f) attaching the reinforcing plate in two or more turns on one side of the lining plate using an adhesive so that the holes cross each other; And (g) attaching a separate outer plate to one side of the reinforcing plate using an adhesive, wherein after step (d) and before step (g) And joining the edge bars of the wood to the edges of the trial.

Here, as a method for horizontally cutting a conventional stone, as shown in FIG. 2, a stone 12 prepared in the form of a plate having a sufficient thickness of 20 mm or more, such as a gypsum board, a metal or a honeycomb panel The stones 12 are horizontally cut in the direction of the arrows using a dedicated cutter device such as a grinder with vibration and separated into two or more slices, It is described that the stiffener 60 can be removed to obtain a stone plate having a thickness of 2 mm to 10 mm.

In addition, prior art references for embodiments using stiffeners attached to stones prepared for horizontal cutting of stones are disclosed in Korean Patent Publication No. 0815267 (published on March 20, 2008) and No. 0815269 (issued on March 3, 2008). 20th Announcement), and Patent Publication No. 0886256 (published on March 2, 2009).

Korean Patent Registration No. 1277887 (published on June 21, 2013) discloses a method for manufacturing a panel for natural stone ornamental finishing and a technique for a decorative finishing material for building using the panel produced therefrom.

The method for manufacturing a decorative panel for natural stone decoration disclosed in the above-mentioned Japanese Patent No. 1277887 is a method for manufacturing a decorative panel for natural stone ornamental finishing, which comprises one kind selected from the group consisting of polyethylene (PE), polypropylene (PP), polystyrene (PS) and polyphenylene oxide And 50 to 95 wt% of a thermoplastic resin having a length of 0.1 to 50 mm, and 5 to 50 wt% of inorganic fibers of carbon fiber are mixed and extruded to put into a mold having a panel shape protruding a honeycomb-shaped rib, An inorganic fiber-reinforced plastic panel having a honeycomb-shaped rib integrally formed on one or both sides of the panel is manufactured, and an adhesive in the form of a urethane, an epoxy oily or water-based adhesive alone or a fiber- And then it is fixed to natural stone such as marble or granite and fixed. Then, it is turned on by using a stone saw with a desired marble thickness, It is said to be finished by minimizing the gem stone part and then polishing it to match the final thickness.

As described above, the natural stone decorative finishing panel disclosed in Patent Registration No. 1277887 is characterized in that, in order to lower the price and weight of the natural stone, a plastic material having a small specific gravity and excellent shock absorbing property is attached, and then the stone is thinned, In order to minimize the number of users.

In particular, the use of too soft plastics can not reinforce marbles with high hardness, so there is a risk of breakage when handling slabs or marbles made of thinner. Therefore, in order to use plastic that maintains the basic stiffness (modulus), thermoplastic resin 50 To 95% by weight of the inorganic fibers and 5 to 50% by weight of the inorganic fibers are mixed and extruded to produce an inorganic fiber-reinforced plastic, and then the panel is manufactured. At this time, ribs are formed on the panel so as to protrude from one side or both sides, ) To form a repeated rectangular plate shape having a honeycomb shape or a hollow shape, or to maintain a hollow shape to minimize warpage.

In the above patent documents, natural stone is described as marble or granite having a thickness of 0.1 mm to 10 mm. However, it is said that processing of a natural stone stone having a thickness of 0.1 mm disclosed in the above patent publication is almost impossible to realize in terms of stone characteristics .

Practically, it is known that polishing can be performed up to about 0.5 mm when polishing the surface of a lime board to realize the texture of the stone surface. In order to process a lime stone plate having a thickness of 0.1 mm, , It is necessary to cut at least a natural stone slab to a thickness of 0.6 mm. However, the technology possessed by the stone processing industry known so far does not have a device and a technique for processing natural stone into a slab of 0.6 mm thickness.

In other words, although it is described that it is possible to process the stone with a 0.1 mm thick gemstone stone plate, it is theoretically possible to make it thin like paper, but the stone component is formed by the grain (silicon, alumina, magnesium, sodium, So that it is impossible to make it as thin as paper.

On the other hand, Korean Patent Laid-Open Publication No. 2011-20680 (published on March 3, 2011) discloses a technique relating to a high hardness stone panel manufacturing apparatus.

As shown in FIGS. 3 to 4, the high hardness stone panel manufacturing apparatus disclosed in the above-mentioned Japanese Patent Laid-Open Publication No. 2011-20680 includes a cutting blade 30 moving on a horizontal guide rail 20 fixed to the ground, At least one jig plate 43 protruding at a predetermined distance from the front surface of the support base 42 and a support plate 42 fixed to one side of the upper side of the movement plate 41 formed at the lower end of the cutting blade 30, At least one clamping jig 60 movably fixed to the front surface of the jig plate 43 and a center portion of the stone plate 55 being fixed between the jig plate 43 and the clamping jig 60 3, the cutting blade 30 has a structure in which a synthetic resin plate 51, a stone plate 55 and a synthetic resin plate 51 are sequentially bonded to each other, (43) and the clamping jig (60) The stone panel 50 is aligned at the center of the stone plate 55 of the stone panel 50 which is clamped between the stones 55 and 55 to produce two stone panels at the same time.

That is, the stone panel manufacturing apparatus provides a device capable of simultaneously producing two stone panels each having a thickness of 2 mm to 3 mm, A synthetic resin plate 51 is adhered to the jig plate 43 and then fixed vertically between the jig plate 43 and the clamping jig 60 and then cut through the cutting blade 30 to produce two stone panels .

However, the synthetic resin plate 51 disclosed in the above-mentioned Japanese Patent Laid-Open Publication No. 2011-20680 does not disclose the specific material and the structure of the synthetic resin plate 51. Therefore, the synthetic resin plate 51 having a known honeycomb structure, It would be appropriate to judge it as.

In addition, since the above-mentioned stone panel manufacturing apparatus has been a goal that can not be achieved by conventionally processing a panel having a thickness of about 2 mm to 3 mm, an object of providing such a device capable of producing such a stone panel has been described It is difficult to apply it to an apparatus for producing a stone panel having a thickness of 2 mm to 3 mm or less.

That is, in the stone panel manufacturing apparatus, the stone plate 51 cut to a thickness of 6 mm to 7 mm needs to be prepared. In the state where the synthetic resin plate 51 is attached thereto, the center of the stone plate 51 is cut, It is necessary to prepare the stone plate 51 cut to a thickness of 6 mm to 7 mm in advance in order to manufacture a stone panel having a thickness of 2 mm to 3 mm since the two stone panels having a thickness of 3 mm can be produced, This was cumbersome and uncomfortable and had many drawbacks.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In order to explain the preferred embodiments of the present invention, the thicknesses of the lines and the sizes of the components shown in the attached drawings may be exaggerated or omitted for clarity and convenience of description, Terms to be given are terms defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator.

As shown in FIGS. 5 and 6, the stone composite panel 100 to which the multilayer resin sheet panel according to the present invention is bonded comprises a multilayer resin sheet panel 120 having a thickness of 0.2 mm to 2 mm, Mm thick stone plate 110 is bonded with an adhesive layer 130.

The stone composite panel 100 to which the multilayered resin sheet panel according to the present invention is bonded may be used for various purposes such as furniture, door, ceiling material, sink, receptacle, illumination lamp, refrigerator door, fire door, general door, Can be used as various interior materials.

Here, the multi-layered resin sheet panel 120 has a structure in which the structure of the resin sheet 121 having a thickness of 0.04 mm to 0.5 mm in the process of manufacturing the resin sheet 121 using one type of synthetic resin is perpendicular to the upper and lower sides And a multilayer structure crossing in a zigzag form so as to have a predetermined thickness.

The synthetic resin made of the resin sheet 121 may be a synthetic resin such as polyethylene (PE), polypropylene (PP), polystyrene (PS), polypropylene copolymer (PPC), polyethylene terephthalate (PPO), modified polyphenylene oxide (MPPO), polyvinyl chloride (PVC), polyketone, ethylene vinyl alcohol copolymer (EVOH), and the like.

The above-mentioned synthetic resins are thermoplastic resins and flame-retardant resins, and are widely used as reinforcing plate materials bonded to stone panels used as interior and exterior materials for construction.

The multilayer structure of the resin sheet 121 for manufacturing the multilayer resin sheet panel 120 is such that the resin structures are stacked in a zigzag form so as to have a structure in which the resin structures are vertically orthogonal to each other, However, it is most preferable to manufacture the third to fifth layers in consideration of the complexity of the manufacturing process and the production cost.

The thickness of the resin sheet 121 used for manufacturing the multilayer resin sheet panel 120 may be in the range of 0.04 mm to 0.5 mm and in the range of 0.2 mm to 2 mm, It is needless to say that the manufacturer is appropriately selected in consideration of the thickness of the resin sheet 121 and the number of layers of the resin sheet 121 to be laminated.

Here, the crossing of the structure of the resin sheet 121 means that the resin sheet 121 is formed into a very thin thickness (for example, a resin sheet having a thickness of 0.04 mm to 0.5 mm in the present invention) by a drawing process or an extrusion process When the sheet is pulled out, the sheet is formed by alternately arranging the sheet in a pulling direction, that is, a direction in which a fiber structure is formed at the pulling, and then thermally pressing the sheet again in a laminated state.

As described above, when the resin sheet 121 is laminated in multiple layers crossing each other and thermally pressed to form the multilayer resin sheet panel 120, the tensile strength, tensile elongation , Flexural modulus, and impact absorbability were significantly improved.

Particularly, since the multilayer resin sheet panel 120 is excellent in shock absorbability, when the stone 101 to be described later is horizontally cut with the stone processing saw 200 to form a very thin stone plate 110, the stone plate 110 is not broken (Modulus) that can be supported firmly and firmly.

The stone plate 110 is generally and preferably used with natural stone such as natural marble, artificial marble, granite, etc., but it is not limited to the above-mentioned stones, , Specifications and the like, as well as stone which can be processed to a thickness of 1 mm to 3 mm according to the present invention and has a unique texture of stone and can be used as an interior material. .

The reason why the thickness of the slab plate 110 is limited to 1 mm to 3 mm in the present invention is that the working limit in the cutting process of the stone 101 and the use of the manufactured stone composite panel 100 This is because lightweight and economic efficiency of the shoe box are considered.

That is, the reason why the working thickness of the slab plate 110 is limited to a minimum of 1 mm is because the range in which the slab plate 110 can be processed as thin as possible according to the present invention is at a level of 1 mm, The reason for limiting the thickness of the stone composite panel 100 to a maximum of 3 mm is that the thickness of the stone plate 110 is 3 mm or more depending on the use of the stone composite panel 100 according to the present invention. This is because it is not desirable from the viewpoint of pursuing light weight and economic efficiency of a shoe box.

Particularly, in the present invention, the minimum thickness capable of machining the stone plate 110 can be up to 1 mm, for example, when the stone 101 prepared to have a thickness of about 20 mm to 50 mm as shown in FIG. 7, It is possible to firmly fix the compression sheet 210 on the basis of the excellent impact absorbability and rigidity (modulus) of the multi-layer resin sheet panel 120 bonded to the lower end surface of the stone 101 when horizontally cutting using the processing saw 200 The seismic resistance against the vibration generated during the processing of the stone 101 and the fragility possessed by the stone itself are reinforced so that the cutting of the stone plate 110 can be performed down to a level of a minimum of 1.5 mm, The surface of the stonewall 110 is polished to a maximum of 0.5 mm through a polishing process.

The adhesive used for the adhesive layer 130 may be any one of a 1-type adhesive, a 2-type adhesive, and an aqueous adhesive.

Fig. 7 schematically shows a manufacturing process of a stone composite panel to which a multilayer resin sheet panel according to the present invention is bonded.

A method of manufacturing a stone composite panel to which a multilayer resin sheet panel according to the present invention is bonded has a step of preparing a multilayer resin sheet panel 120 first.

That is, the thermoplastic resin and flame-retardant resin types such as polyethylene (PE), polypropylene (PP), polystyrene (PS), polypropylene copolymer (PPC), polyethylene terephthalate (PET), polyphenylene oxide A synthetic resin selected from the group consisting of polypropylene (PPO), modified polyphenylene oxide (MPPO), polyvinyl chloride (PVC), polyketone, ethylene vinyl alcohol copolymer (EVOH) A resin sheet 121 having a thickness of 0.04 mm to 0.5 mm is laminated so as to have a structure in which the resin structures are perpendicular to each other so as to cross each other in a staggered manner, .

Then, there is a step of joining the pre-prepared stone and the multi-layered resin sheet panel.

That is, the multi-layered resin sheet panel 120 prepared as described above is bonded to the lower end surface of the stone 101 having a predetermined thickness (for example, 20 mm to 50 mm thickness) . At this time, it is preferable that the stone 101 is selected from natural marble, artificial marble, and granite.

The adhesive applied to the lower end surface of the stone 101 may be selected from among a 1-type adhesive, a 2-type adhesive and an aqueous adhesive in consideration of the adhesive property between the stone 101 and the multi- .

When the multilayer resin sheet panel 120 is bonded to the lower surface of the stone by an adhesive and cured, the stone plate 110 having a predetermined thickness is cut and removed from the stone 101.

At this time, in order to cut and remove the stone plate 110 having a predetermined thickness from the stone 101, it is necessary to firstly fix the stone 101 to be firmly fixed so as to catch vibration generated in the cutting process of the stone 101 .

To this end, the multi-layered resin sheet panel 120 on the pedestal 220 is pressed through the upper compression plate 210 to firmly reinforce and fix the multi-layer resin sheet panel 120 so as to cope with vibrations and the like.

The horizontal cutting operation is performed in a state in which the manufacturer prepares the stone processing saw 200 prepared in accordance with the thickness of the stone plate to be processed (that is, predetermined thickness 102) horizontally on one side of the stone 101 .

At this time, the stone processing saw 200 uses an artificial diamond saw that is usually used for cutting stone.

Particularly, according to the present invention, a stone plate 110 having a thickness of 1.5 mm from the stone 101 having a predetermined thickness (for example, 20 mm to 50 mm thickness) is repeatedly It can be cut off and removed.

That is, the multi-layer resin sheet panel 120 is bonded to the lower end surface of the stone 101 having a thickness of 20 mm to 50 mm, which is prepared in advance, and the predetermined thickness 102, for example, , A 1.5 mm thick stone plate 110 is first horizontally cut and removed and then the top face of the cut stone 101 is smoothly polished or otherwise polished. It is possible to repeatedly cut the stone plate 110 with a thickness of 1.5 mm.
