Manufacturing method of overlay veneer for furniture with furniture and furniture produced therefrom The present invention relates to a overlay overlay plate.

화장합판(Fancy plywood, Decorative plywood)은 통상 합판의 표면에 화장효과를 목적으로 하여 얇은 다판(찍기판) 주로 슬라이드 단판을 붙인 것을 일컫는 것 으로, 요즈음은 멜라민 수지 또는 디아릴프타레이트수지 함침 오버레이지나, 화장모양지 또는 화장모양 인쇄 염화비닐수지 필름등을 표면에 붙인 합판을 포함하는 개념으로 사용되고 있다.Fancy plywood (Decorative plywood) refers to attaching a thin multi-plate (cut board) mainly slide end plate on the surface of plywood for the purpose of cosmetic effect. It is used as a concept including plywood on which a cosmetic paper or a cosmetic printed vinyl chloride resin film is attached to a surface.

이와같이 일반적으로 알려진 화장판 또는 화장용 오버레이 합판은, 폴리비닐클로라이드 수지필름 또는 폴리에스테르피름에 무늬를 인쇄 또는 착색하고 이들 필름을 합판 및 경질섬유판상에 패스트화(pasting)하여 얻는 열가소성수지 화장판 및 화장용 오버레이 합판을 들 수 있다. Commonly known decorative plates or cosmetic overlay plywood is a thermoplastic resin decorative plate obtained by printing or coloring a pattern on a polyvinyl chloride resin film or polyester film and pasting these films onto plywood and a hard fiber board, and Cosmetic overlay plywood.

이와같이 여러 모양 또는 무늬가 인쇄, 착색된 여러재질의 필름 등의 비닐시트(Vinyl sheet)를 이용하는 화장판의 경우에 EVA 열가소성 접착제를 사용하여 필름층과 종이층간을 접착하게 되고, 그 필름 상면에 우레탄 도료등을 이용, 도포하여 얻게 되는데, 이와같이 얻게 되는 화장판의 경우 유연성을 갖으며 가공이 자유로운 장점이 있는 반면에, 표면경도·내열성 및 내화학역품성이 결여되는 문제점이 있고, 냉압으로 얇은 모양지와 필름코팅층을 접합한 후 도료층을 형성하게 되므로수분침투현상에 상당히 약하여, 소량의 수분침투시에도 접착층이 벌어지는 문제점이 있고, 햇빛등에 쉽게 변색되는 등의 취약점이 발견되고 있다.Thus, in the case of a cosmetic plate using a vinyl sheet such as a film of various shapes or patterns printed or colored, EVA thermoplastic adhesive is used to bond the film layer and the paper layer to the upper surface of the film. It is obtained by using a coating, etc., the decorative plate obtained in this way has the advantages of flexibility and free processing, while lacking surface hardness, heat resistance and chemical resistance properties, thin shape by cold pressure Since the coating layer is formed after bonding the paper and the film coating layer, it is very weak in water permeation phenomenon, there is a problem that the adhesive layer is opened even when a small amount of water infiltration, and a weakness such as discoloration in sunlight is found.

또한 상기한 화장판 이외에 착색 또는 무늬 인쇄된 무늬지나 직물의 시이트(sheet)를 멜라민수지, 벤조구아나민수지, 페놀수지 또는 불포화 폴리에스테르수지 등으로 수차례 함침시키거나, 동시에 이들 수지의 공중 축합 생성물로 수차례 함침시키고 이어서 함침 시이트(sheet)를 경화 시키는 것으로 이루어진 방법으 로 제조되는 열경화성수지 화장판 또는 이와 동일한 종이나 직물의 함침 시이트를 제조한 후 이들 시이트를 기질과 일체식으로 경화시키는 방법에 의해 제조된 열경화성수지 화장판·오버레이 화장판 등을 들 수 있다.In addition to the above-described decorative board, sheets of colored or patterned printed paper or fabrics are impregnated with melamine resin, benzoguanamine resin, phenol resin or unsaturated polyester resin several times, or at the same time, co-condensation products of these resins. And a method of curing the sheets integrally with the substrate after preparing a thermosetting resin decorative plate or an impregnated sheet of the same paper or fabric, which is produced by a method comprising impregnating with a number of times and then curing the impregnated sheet. Thermosetting resin board | plate, Overlay board | plate etc. which were manufactured by this are mentioned.

상기한 열경화성수지 화장판 또는 오버레이 화장판(이하 화장판으로 통칭함)중 가장 많이 사용되는 대표적 화장판은 멜라민시이트(Melamin sheet)를 열압하여 접착시킨 LPM(Low presure melamin)을 들 수 있는데, 상기 LPM의 제조공정을 간략시 서술하면 롤상으로 권치된 무늬 인쇄된 무늬지나 직물 시이트를 요소수지조내에 함침시킨 후 멜라민수지조에 재차 함침 처리하고 건조시켜 얻은 제품을 합판 일면에 180℃의 온도와 20 kg/㎠으로 40초간 열압하여 형성하게 된다.Representative of the most popular of the thermosetting resin decorative plate or the overlay decorative plate (hereinafter referred to as the decorative plate) is a low presure melamin (LPM) bonded by hot-melting a melamine sheet (Melamin sheet), Briefly describing the manufacturing process of LPM, the product obtained by impregnating the rolled pattern printed pattern or fabric sheet into the urea resin tank, and then again impregnating and drying the melamine resin tank and drying the product obtained at a temperature of 180 ° C. and 20 kg on one side of the plywood It is formed by thermal pressure for 40 seconds at / cm 2.

이와같이 얻게 되는 LPM은 상기한 바와 같이 멜라민시트등을 열경화처리하여 얻게 되므로, 그로부터 얻게 되는 화장판은 내열성 및 내화학약품성에 있어서 뛰어난 효과와, 표면경도 등의 기계물리적 성질등이 우수한 효과를 발휘할 수 있으나 제품의 가격이 고가이고, 유연성이 결핍되어 있는 문제점이 지적되고 있다.Thus obtained LPM is obtained by heat-curing the melamine sheet and the like as described above, the cosmetic plate obtained therefrom exhibits excellent effects in heat resistance and chemical resistance, and mechanical and physical properties such as surface hardness. However, the problem is that the price of the product is expensive and lacks flexibility.

한편, 멜라민수지를 사용하여 제조되는 화장판 및 오버레이 합판등이 있는데 이와같은 경우 이들을 발포하는 과정에서 최적 조건하에서 경화시켰을 때 광택, 내수성 및 내화학약품성에 있어서 어느정도 개선을 나타내고 있으나, 그럼에도 불구하고 경화가 더 진행되게 되면, 내균열성이 저하되는 단점이 있음을 발견하게 되었다.On the other hand, there are decorative boards and overlay plywood manufactured using melamine resin, and in such a case, there is some improvement in gloss, water resistance, and chemical resistance when cured under optimum conditions in the process of foaming them. As it proceeds further, it has been found that there is a disadvantage that the crack resistance is lowered.

따라서 본 발명은 상기한 문제점을 해결하기 위해 안출한 것으로서,Therefore, the present invention has been made to solve the above problems,

비교적 저가의 오버레이 화장판을 제공하면서도 상당한 표면경도 및 강도를 갖도록 하여 외부로부터의 충격이나 접촉과정에서도 화장판의 표면층이 손쉽게 스크래칭되는 현상이 발생되는 것을 방지하여, 가구재등의 사용수명을 현저히 상승시킴은 물론, 광택·유연성·내광성·내청성·내수성·내화확약품성 및 내균열성에 있어서 뛰어난 가구재용 오버레이 화장판을 제공하는데 그 목적이 있다.
It provides a relatively low-cost overlay board, but has a considerable surface hardness and strength to prevent the surface layer of the board from being easily scratched during impact or contact from the outside, thereby significantly increasing the service life of furniture. In addition, the object of the present invention is to provide an overlay decorative plate for furniture having excellent gloss, flexibility, light resistance, rust resistance, water resistance, fire resistance and crack resistance.

상기한 목적을 달성하기 위한 본 발명은,The present invention for achieving the above object,

Resin layer coating step (S3) to have a resin layer 30,

상기 수지층도포공정(S3)으로부터 얻은 제품을 100~120 ℃를 유지하는 건조로(미도시)를 통과시켜 가건조시킨 후, 열압프레스(2)에서 120~140 ℃ 온도, 14~16 kg/㎠ 압력으로 열압 처리하는 열압프레싱 공정(S4)으로 이루어지는 것을 구성상 특징으로 한다.After drying the product obtained from the resin layer coating step (S3) through a drying furnace (not shown) maintaining 100 ~ 120 ℃, 120 ~ 140 ℃ temperature, 14 ~ 16 kg / in a hot press (2) It is characterized by the structure consisting of the thermopressurizing process S4 which carries out a hot pressurization by cm2 pressure.

이하 본 발명의 바람직한 실시예를 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail.

(제1공정 - 접착제도포공정 ; S1)(Step 1-Adhesive Coating Process; S1)

본 발명에서 먼저 PB, MDF, HDF 등 고·중·저밀도 압축강화목으로되는 패널 (10)이나 또는 일반 합판등으로 되는 패널(10) 일면 또는 양면에 접착제층(11)을 형성하게 된다.In the present invention, first, the adhesive layer 11 is formed on one or both surfaces of the panel 10 made of high, medium and low density compressed hardened wood such as PB, MDF, HDF, or general plywood.

이때 본 발명에서 채택·채용되는 접착제는 가구재의 특성을 감안하여 장시간 사용시에도 접착력 및 내수성·내열성·내한성 등을 유지할 수 있도록 하는 것이 바람직한데, 이와같은 특성을 갖도록 하기 위해 열경화성수지계열인 요소수지 계열(UREA계)의 접착제를 이용하는 것이 바람직하다.At this time, it is preferable that the adhesive adopted and employed in the present invention can maintain the adhesive strength, water resistance, heat resistance, cold resistance, etc. even in the long-term use in consideration of the characteristics of the furniture, in order to have such characteristics, urea resin series of thermosetting resin series It is preferable to use the adhesive of (UREA type).

이때, 상기한 접착제에 티탄계의 충진제를 2% 중량부 혼합하여 접착시공함으로써, 접착제와 혼화되어 후술하는 PAPER 접착공정(S2)시 PAPER(20) 조직의 미세구멍을 메우면서 오버레이 화장판의 표면층에 미려한 질감효과를 발현할 수 있다.At this time, by mixing 2% by weight of a titanium-based filler to the adhesive, the adhesive layer is mixed with the adhesive to fill the micropores of the PAPER 20 tissue during the PAPER bonding process (S2) described later, the surface layer of the overlay decorative plate Beautiful texture can be expressed.

(제2공정 - PAPER 접착공정 ; S2)(2nd process-PAPER bonding process; S2)

본 공정은 패널(10) 상면에 접착제층(11)을 형성하는 제1공정인 접착제도포공정(S1)을 통해 얻은 패널(10) 접착제층(11) 상면에 무늬나 모양 등이 인쇄된 PAPER(20)를 접착하기 위한 공정으로, 상기 PAPER(20)는 먼저 표면마감재로서의 유연성·강도·내수성 등을 보강하기 위해 UREA 계열의 수지를 7~8 g/ft2 가량 함침시킨다. 이와같은 조건에 의해 함침처리함으로써 PAPER(20)층이 패널(10)로부터 박리되는 현상을 방지할 수 있다.This process is the first step of forming the adhesive layer 11 on the upper surface of the panel 10, the PAPER (printed pattern or shape, etc. are printed on the upper surface of the adhesive layer 11 of the panel 10 obtained through the adhesive coating process (S1) ( 20) In the process for bonding, the PAPER 20 is first impregnated with about 7 ~ 8 g / ft 2 of the UREA-based resin to reinforce the flexibility, strength, water resistance and the like as a surface finish material. By the impregnation treatment under such conditions, the phenomenon that the PAPER 20 layer is peeled from the panel 10 can be prevented.

이와같이 선 함침처리되어 얻은 PAPER(20)를 패널(10)의 접착제층(11)에 접착시키기 위해 120~140℃의 온도로 14~16 kg/㎠ 의 압력이 제공되는 롤프레스(Roll press)(1)로 1차 접착시켜 완전한 내수성 및 접착력을 부여한다.In order to bond the PAPER 20 obtained by the pre-impregnation process to the adhesive layer 11 of the panel 10, a roll press provided with a pressure of 14 to 16 kg / cm 2 at a temperature of 120 to 140 ° C ( Primary bonding with 1) gives complete water resistance and adhesion.

즉, 도 3b에서 보는바와 같이 제1공정에 의한 접착제층(11)이 상기 PAPER(20)가 패널(10) 상면에 가접된 상태에서 롤프레스(1)를 통과하게 되면, 접착제층(11)의 접착제가 PAPER(20)의 미세한 조직사이로 침투되면서 가건조, 경화되므로 접착력이 상당히 강화되는 효력이 있으므로 PAPER(20)가 손쉽게 박리되지 못한다.That is, as shown in FIG. 3B, when the adhesive layer 11 according to the first process passes the roll press 1 in a state where the PAPER 20 is welded to the upper surface of the panel 10, the adhesive layer 11 is formed. Since the adhesive penetrates between the microstructures of the PAPER 20 and is temporarily dried and cured, the adhesive force is significantly enhanced, so that the PAPER 20 cannot be easily peeled off.

한편 도 3c에서 보듯이 상기 무늬 등이 인쇄된 PAPER(20)를 음각(陰角)으로 부식시켜 엠보싱(Embossing) 처리된 표면을 갖는 스틸롤(Steel roll)(4)을 이용, 통과시키면서 PAPER(20) 내부에 UREA계 수지를 함침시켜 종래와 같이 PAPER(20)층이 패널(10)로부터 분리되는 결점을 보완하고, 상기 PAPER(20) 자체에 내수성 및 표면강도, 표면경도를 지닐 수 있도록 별도 가공처리할 수 있다.Meanwhile, as shown in FIG. 3C, the paper is printed using a steel roll 4 having an embossed surface by corroding the printed paper. 20) Impregnating a UREA-based resin inside to compensate for the defect that the PAPER (20) layer is separated from the panel 10 as in the prior art, and to separate the PAPER (20) itself to have water resistance, surface strength, surface hardness It can be processed.

여기서 미설명부호 3은 함침로울러를, 미설명부호 4는 스틸롤을 표시한다.Reference numeral 3 denotes an impregnation roller, and reference numeral 4 denotes a steel roll.

(제3공정 - 수지층도포공정 ; S3)(Step 3-Resin Layer Coating Process; S3)

본 공정은 상기한 각 공정을 거쳐 얻은 제품인 패널(10)의 PAPER(20) 상면에 다시 수지층(30)을 도포처리하게 되는데, 패널(10)에 수분침투에 의한 표면변색, 변형, 이물질등에 의한 오염을 방지하고, 내수성·내열성·내한성을 갖도록 하기 위해 멜라민계열의 수지에 3 % 중량부의 실리콘계열 수지를 혼합하여 상기 PAPER 접착공정(S2)에 의해 얻은 1차 제품의 PAPER(20) 상면에 4~5 g/ft2 으로 도포처리하여 수지층(30)을 갖도록 한다.In this process, the resin layer 30 is applied to the upper surface of the PAPER 20 of the panel 10, which is a product obtained through the above-described processes, and the panel 10 is subjected to surface discoloration, deformation, foreign matters, etc. due to moisture penetration. In order to prevent contamination by water and to have water resistance, heat resistance, and cold resistance, 3% by weight of silicone-based resin is mixed with melamine-based resin to the upper surface of the PAPER 20 of the primary product obtained by the PAPER bonding step (S2). The coating is performed at 4 to 5 g / ft 2 to have the resin layer 30.

상기 실리콘계열 수지를 혼합처리하게 되면, 패널(10) 제품의 표면의 슬립성 및 열판 내부에서의 이형성을 향상 시킬 수 있다.When the silicon-based resin is mixed, the slip property of the surface of the panel 10 product and the releasability inside the hot plate may be improved.

(제4공정 - 열압프레싱공정 ; S4)(Step 4-Hot Pressing Process; S4)

상기와 같이 PAPER(20) 상면에 재차 수지층(30)을 도포 처리하는 제3공정을 통해 얻은 패널(10)을 건조, 열압 처리하여 완전한 제품을 얻는 단계로, 상기 공정에 의해 얻은 제품을 100~120℃의 온도를 유지하는 도시하지 않은 별도의 건조로에 투입, 통과되도록 하여 가건조시킨 다음, 120~140℃의 온도를 갖으며 14~16 kg/㎠ 의 압력을 갖는 열압프레스(2)에서 열압프레싱하여 완전한 가구용 화장판의 패널(10)을 얻을 수 있었다. As described above, the panel 10 obtained through the third process of applying the resin layer 30 to the upper surface of the PAPER 20 is dried and hot-pressed to obtain a complete product. Into a separate drying furnace (not shown) to maintain a temperature of ~ 120 ℃ to pass through the drying, and then in a thermo-pressure press (2) having a temperature of 120 ~ 140 ℃ and a pressure of 14 ~ 16 kg / ㎠ The hot pressing was able to obtain a panel 10 of a complete furniture decorative plate.

상기한 공정을 통해 얻은 제품 즉, 화장판을 이용하여 각종 가구재, 음향기기 케이스, 주방가구 등에 채택, 적용하여 시공하게 되면 패널(10)에 접착되는 PAPER(20)간 접착력의 강화로 쉽게 박리되는 현상을 완벽하게 방지될 수 있고, PAPER(20) 상면으로 다시 수지층(30)이 형성되므로 본 발명의 패널(10)을 이용한 화장판에 의해 각종 가구등을 생산, 사용하였을 경우 장기간 사용에 따른 외부로부터의 수분침투등에 의한 변색, 탈색, 변형, 오염등을 미연에 방지할 수 있었으며, PAPER 의 표면층이 강한 표면경도, 표면강도 및 내수성, 내한성, 내마모성 등의 물성을 취득하게 되어, 외부로부터의 충격 또는 스크래칭 등에 의한 표면의 손상, 손괴 등이 발생되지 않았다. When the product obtained through the above process, that is, using a makeup plate, is adopted and applied to various furniture materials, acoustic device cases, kitchen furnitures, and the like, it is easily peeled off by reinforcing the adhesive force between the PAPERs 20 adhered to the panel 10. The phenomenon can be completely prevented, and since the resin layer 30 is formed on the upper surface of the PAPER 20, when various furnitures are produced and used by using a decorative plate using the panel 10 of the present invention, it can be used for a long time. It is possible to prevent discoloration, discoloration, deformation, and contamination due to moisture penetration from the outside, and the surface layer of PAPER acquires physical properties such as strong surface hardness, surface strength and water resistance, cold resistance, and abrasion resistance. No damage or damage to the surface due to impact or scratching occurred.

따라서 본 발명에 의하면, 패널 일면 또는 양면으로 열경화성수지계열인 요소수지 계열의 접착제를 도포하고, 그 접착제층 상면에 UREA계열 수지에 함침 처리된 각종 무늬나 문양등이 인쇄된 PAPER를 롤프레스에 의해 적정 온도 및 압력으로 롤링프레싱 처리한 후, 재차 PAPER 상면에 멜라민계 수지를 도포 처리하여 수지층을 형성한 다음 건조로와 열압프레싱 가공에 의해 화장판을 얻게 되므로, 그 가공공정이 간단하고 종래와 같은 LPM 화장판과 같은 고가의 제품을 대체할 수 있는 저 가의 제품 생산이 가능한 효과를 기대할 수 있다.Therefore, according to the present invention, by applying a urea resin-based adhesive that is a thermosetting resin series to one or both sides of the panel, and printing various patterns or patterns impregnated with UREA resin on the upper surface of the adhesive layer by roll press After rolling pressing at the proper temperature and pressure, melamine-based resin is again applied to the upper surface of the paper to form a resin layer, and then a drying plate and a hot plate pressing are obtained to obtain a decorative plate. It is expected to produce low-cost products that can replace expensive products such as LPM boards.

또한 본 발명에 의해 얻은 화장판의 표면경도 및 강도에 의해 화장판의 표면층이 손쉽게 스크래칭되는 현상이 발생되는 것을 방지할 수 있고, 장시간 사용하더라도 오버레이 화장판의 PAPER 층이 박리되거나 수분침투에 의한 표면변색, 변형, 오염등을 완벽하게 방지할 수 있어, 가구재등의 사용수명을 현저히 상승시킴은 물론, 광택·유연성·내광성·내청성·내수성·내화확약품성 및 내균열성에 있어서 뛰어난 가구재용 오버레이 화장판을 제공할 수 있는 장점이 있다.
In addition, it is possible to prevent the phenomenon that the surface layer of the makeup plate is easily scratched by the surface hardness and strength of the makeup plate obtained by the present invention, and even if it is used for a long time, the PAPER layer of the overlay makeup plate is peeled off or the surface by moisture penetration Discoloration, deformation and contamination can be completely prevented, which greatly increases the service life of furniture materials, as well as overlay material for furniture that is excellent in gloss, flexibility, light resistance, blue resistance, water resistance, fire resistance chemical resistance and crack resistance. There is an advantage in providing a floor covering.
