본 발명은 건축용 실내 마감재, 각종 경량 구조물 및 조명기구 등에 사용되는 합성수지 패널의 제조방법에 관한 것으로, 투명 또는 반투명 투명합성수지판(10) 배면에 목제막체(木製膜體)(11)가 접착된 합성수지 패널을 구성하되, 목제막체(11)와 투명합성수지판(10)간에는 물 및 톨루엔(toluene)으로 희석된 저점도 EVA 접착액(12)이 함침되어 압착된 접착면이 형성되고, 목제막체(11)의 접착면 이면에는 합성수지 필름(15)이 라미네이트(laminate)되어, 한쌍의 투명합성수지판(10)을 샌드위치형으로 적층하지 않고도 목제막체(11) 부착형 합성수지 패널을 제조할 수 있도록 한 것이다.
The present invention relates to a method of manufacturing a synthetic resin panel for use in interior finishing materials for construction, various lightweight structures and lighting apparatuses, and more particularly to a method of manufacturing a synthetic resin panel using a transparent or semitransparent transparent synthetic resin plate 10 with a wooden film body 11 A joint surface between the wood film body 11 and the transparent synthetic resin plate 10 is formed by impregnating a low viscosity EVA adhesive liquid 12 diluted with water and toluene to form an adhered surface, The synthetic resin film 15 is laminated on the back of the adhesive surface of the body 11 so that the synthetic resin panel with the wooden film body 11 can be manufactured without stacking the pair of transparent synthetic resin plates 10 in a sandwich form .

합성수지판은 가공이 용이하고 경량일 뿐 아니라 비교적 자유로운 성형이 가능하므로 건축용 실내 마감재는 물론, 간판, 조명기구 및 각종 잡화의 제조에 널리 사용되고 있다.Synthetic resin plates are widely used in the manufacture of signboards, lighting fixtures and various kinds of miscellaneous goods as well as architectural interior finishing materials because they are easy to process, lightweight and relatively freely formable.

특히, 투명 또는 반투명 합성수지판의 경우 취성파괴 가능성이 상대적으로 낮은 특성이 있으므로 유리판의 대용품으로서 통용되고 있으며, 투명 또는 반투명 합성수지판의 표면에 합성수지 시트, 지물류 또는 박판 가공된 목재 등을 부착하여 다채로운 문양을 표현함으로써, 심미성 및 상품성을 확보한 다양한 가공품이 개발된 바 있다.In particular, transparent or translucent synthetic resin plates are used as a substitute for glass plates because they have a relatively low possibility of brittle fracture, and synthetic resin sheets, paper or wood-processed woods are attached to the surfaces of transparent or translucent synthetic resin plates, By expressing the patterns, a variety of processed products that have acquired esthetics and merchantability have been developed.

합성수지판 가공품 소재 중 원목을 미세한 두께로 절단한 목재 박판, 또는 목재 펄프를 주 원료로 생산되는 한지(韓紙) 등 지물류를 포함하는 목제막체(木製膜體)는 특유의 자연스럽고 미려한 무늬로 인하여 합성수지판 부착재로서 각광받고 있으며, 이러한 목제막체 부착 합성수지판 가공 기술로서 아크릴판이 적용된 특허 제916234호 및 실용신안등록 제400262호를 들 수 있다.
The wooden film body, which is made of synthetic resin plate processed wood, is made of wood thin sheet cut into small thickness of wood, or paper such as Hanji which is mainly made of wood pulp, has a unique natural and beautiful pattern As a processing technology for a synthetic resin plate having a wood film body, Patent No. 916234 to which an acrylic plate is applied, and Utility Model Registration No. 400262 can be cited.

특허 제916234호 및 실용신안등록 제400262호는 아크릴판에 접착되는 목제막체로서 각각 목재 박판 및 한지를 적용한 것이나, 목제막체의 구체적인 성상에만 차이가 있을 뿐 기본적인 적층 내지 부착방식은 사실상 동일한 것으로, 일단 목제막체의 양면에 속건성(速乾性) 접착제를 도포, 건조하여 고무층 또는 수지층 즉, 가열융착시의 용융층을 형성한 후, 한쌍의 아크릴판 사이에 적층하고 가열 압착하여 층간 융착이 이루어지도록 하는 것이다.Patent No. 916234 and Utility Model Registration No. 400262 disclose that a wooden film sheet adhered to an acrylic plate is made by applying a thin wooden plate and a paper sheet respectively but the basic lamination or attachment method is substantially the same , A quick drying adhesive is first applied to both sides of the neck of a neck wrapper and dried to form a rubber layer or a resin layer, that is, a melted layer at the time of heat fusion bonding, then laminated between a pair of acrylic plates, .

따라서, 목제막체를 합성수지판에 부착하는 공정에 있어서 가열이 필수적으로 수반될 수 밖에 없으며, 일반적으로 열가소성 수지가 압출 또는 사출성형되어 제조되는 합성수지판의 특성상 가열시 휨 및 비틀림 등의 구조적 변형이 유발될 수 있음은 물론, 설령 구조적 변형이 최소화된다 하여도 합성수지판 표면의 열변성으로 인한 불요(不要) 경화, 광택 및 투명도 저하가 발생되는 심각한 문제점이 있었다.Therefore, in the step of adhering the wood film to the synthetic resin plate, heating is inevitably accompanied. In general, due to the characteristics of a synthetic resin plate produced by extrusion or injection molding of a thermoplastic resin, a structural deformation such as warping and twisting occurs And even if the structural deformation is minimized, there is a serious problem that unnecessary curing, gloss and transparency are lowered due to thermal deformation of the surface of the synthetic resin plate.

이러한 문제점을 해결하기 위하여 목제막체와 아크릴판 등 합성수지판을 열 융착하는 것이 아니라 상용 접착제를 도포하여 접착하는 방안을 고려할 수 있으나, 이는 합성수지 필름 등을 사용한 일반적인 표면 마감 처리인 래핑(wrapping)과 일맥상통하는 기법으로서, 접착면내 기포 잔류 및 접착불량 등의 문제가 빈발할 뿐 아니라, 접착공정 자체 또는 후처리 공정인 접착제의 건조 및 경화공정간 접착대상 필름에 불필요한 응력이 발생되고 이러한 응력이 합성수지판에도 전달되어 합성수지판이 변형되는 심각한 문제점이 발생될 수 있다.In order to solve such a problem, it is possible to consider a method of applying and bonding a commercial adhesive agent instead of thermally fusing a synthetic resin plate such as a wood film body and an acrylic plate. However, this is a general surface finishing treatment using a synthetic resin film, There is a problem that not only the bubble remains in the adhesive surface and problems such as adhesion failure occur frequently but also an unnecessary stress is generated in the adhesive film between the adhesive process itself and the drying and curing process of the adhesive which is a post- So that the synthetic resin plate is deformed.

즉, 아크릴판 등 합성수지판에 필름을 접착함에 있어서 필름을 평활하게 전개하기 위하여 필름의 외곽부에 인장력을 가하게 되는데 이때 인장 변형된 필름이 접착후 수축 복원되면서 합성수지판이 휘거나 비틀리게 되는 것이다.That is, when a film is adhered to a synthetic resin plate such as an acrylic plate, a tensile force is applied to the outer periphery of the film in order to smoothly expand the film. In this case, the tensile deformed film is shrunk and restored after the adhesion so that the synthetic resin plate is bent or twisted.

또한, 목재 박판 및 한지(韓紙) 등의 목제막체(木製膜體)는 조직 특성상 완전히 평활한 표면을 형성할 수 없으므로, 종래와 같은 접착 방식으로는 긴밀하고 균일한 접착상태를 형성할 수 없을 뿐 아니라, 접착과정에서 목제막체가 파단되는 등의 문제가 발생될 수 있다.In addition, since the wooden film body such as the wooden thin plate and the Korean paper can not form a completely smooth surface due to the nature of the tissue, a uniform and uniform bonding state can be formed by the conventional bonding system And there is a problem that the neck of the neck is broken during the bonding process.

그 뿐 아니라, 열융착 및 접착을 막론하고 종래의 목제막체 부착 합성수지 판재에 있어서는 접착제의 유효 성분으로 융착층 또는 접착층을 형성하는 고무 또는 수지 용질이 실질적 접착력을 발현하게 되는데, 이들 고무 또는 수지 용질은 전형적인 가연성 물질인 바, 해당 판재를 이용한 최종 제품 제작시 절단과정에서 절단공구의 마찰로 인하여 쉽게 연소되므로 절단부위가 변색되거나 절단부위에 과도한 스크랩(scrap)이 형성되어 사상(仕上)작업 등 별도의 후처리 공정이 소요되는 심각한 문제점이 있다.In addition, in a conventional synthetic resin sheet material having a wood film body, regardless of thermal fusion bonding and adhesion, rubber or resin solute which forms an adhesive layer or an adhesive layer as an effective component of an adhesive exhibits substantial adhesive force. These rubber or resin solute Is a typical combustible material. It is burned easily due to the friction of the cutting tool during the cutting process when the final product is manufactured using the plate material. Therefore, the cutting part is discolored or an excessive scrap is formed at the cutting part, There is a serious problem that a post-treatment process is required.

특히, 절단 선형의 자유로운 설정 및 신속한 작업이 가능하여 최근 각광받고 있는 레이저절단에 의한 가공시, 접착제내 고무 및 수지 용질이 맹렬하게 연소되면서 변색 및 열변형이 과도하게 확대되고 결국 심각한 제품 불량이 유발되는 문제점이 있다.In particular, it is possible to freely set the cutting linear shape and to perform the rapid work, so that the rubber and the resin solute in the adhesive are fiercely burned during the processing by the laser cutting, which has recently been spotlighted, so that the discoloration and thermal deformation are excessively enlarged, .

한편, 전술한 종래의 목제막체 적용 합성수지판은 모두 샌드위치형 즉, 한쌍의 합성수지판 사이에 목제막체가 적층된 구조를 가지는 것으로, 완성된 패널의 양면에 합성수지판이 구성되는데, 목제막체 적용 합성수지판은 건축용 마감재 등 대부분의 용처에서 양면이 아닌 어느 일면만이 외부로 노출되는 바, 양면에 합성수지판이 구성될 필요는 없음에도 불구하고, 열 융착과정에서 목제막체 표면이 손상되는 것을 방지하고 완성품의 배면 방수성 등을 확보하기 위하여 불가피하게 양면에 합성수지판을 구성하고 있는 실정이며, 이로 인하여 과도한 제조비용이 소요될 뿐 아니라, 완제품의 경량화 및 박판화에도 한계가 있을 수 밖에 없었다.
Meanwhile, the conventional synthetic resin plates for use in the above-described conventional wooden film assemblies have a structure in which a wooden film body is sandwiched between a pair of synthetic resin plates, and a synthetic resin plate is formed on both sides of the completed panel. It is possible to prevent the surface of the wood film body from being damaged during the heat welding process and to prevent the damage of the finished product In order to secure the back waterproofness of the back side, a synthetic resin plate is inevitably formed on both sides. In addition to this, excessive manufacturing cost is required and there is a limit to the weight reduction and thinning of the finished product.

도시된 실시예에서는 목제막체(11)로서 원목을 미세하게 박판 가공한 목재 판재가 적용되었으며, 목제막체(11)가 부착되는 판재로는 투명 또는 반투명 합성수지판이 적용되어 완성된 합성수지 패널에 자연스러운 나뭇결 무늬가 표현될 수 있도록 구성된다.In the illustrated embodiment, a wood plate material in which the wood is thinly processed as a wood film body 11 is applied, and a transparent or translucent synthetic resin plate is used as a plate material to which the wood film body 11 is attached, And a grain pattern can be expressed.

본 발명에 있어서 구조체 역할을 수행하는 투명합성수지판(10)으로는 투명 폴리카보네이트(polycarbonate), 투명 PVC(Polyvinyl Chloride), 투명 아크릴 또는 투명 PET(PolyEthylene Terephthalate)를 적용하는 것이 바람직하며, 이로써 우수한 내충격성을 확보할 수 있다.As the transparent synthetic resin plate 10 that serves as a structural body in the present invention, transparent polycarbonate, transparent PVC (polyvinyl chloride), transparent acrylic or transparent PET (PolyEthylene Terephthalate) is preferably applied, The impact resistance can be ensured.

도 2는 본 발명의 단면을 도시한 것으로 동 도면의 타원내 확대부에서와 같이, 목제막체(11) 조직이 압축된 상태로 경화된 접착액(12)과 함께 평활한 접착면을 형성하면서 투명합성수지판(10) 배면에 접착됨을 알 수 있으며, 이와 같은 긴밀하고 평활한 접착 상태는 도 3에서와 같은 과정의 처리를 통하여 달성될 수 있는데, 이를 상세히 설명하면 다음과 같다.Fig. 2 shows a cross section of the present invention. As in the enlarged part in the ellipse in Fig. 2, the structure of the neckline 11 is formed in a compressed state with the cured adhesive liquid 12 It can be seen that the transparent synthetic resin sheet 10 is adhered to the back surface of the transparent synthetic resin sheet 10. Such a tight and smooth adhesion state can be achieved through the process as shown in FIG. 3, which will be described in detail as follows.

도 3에서와 같이, 우선 도면상 상면으로 도시된 투명합성수지판(10) 배면에 목제막체(11)를 접착하여 투명합성수지판(10) 접착체를 구성함으로써 본 발명이 개시되는데, 투명합성수지판(10)과 목제막체(11)의 접착에는 저점도 접착액(12)이 사용되며, 목제막체(11)의 조직내에 접착액(12)이 함침된 상태로 투명합성수지판(10)과 접착된다.As shown in FIG. 3, the present invention is first disclosed by bonding a wooden film body 11 to the rear surface of a transparent synthetic resin plate 10, which is shown as an upper surface in the drawing, to form an adhesive body of the transparent synthetic resin plate 10, Viscosity adhesive liquid 12 is used for adhering the wood film 11 and the transparent synthetic resin plate 10 in a state in which the adhesive liquid 12 is impregnated in the structure of the wooden film body 11, .

이때, 접착액(12)의 도포는 투명합성수지판(10) 또는 목제막체(11) 어느 쪽에 실시하여도 무방하나, 박판체인 목제막체(11)의 유연성을 감안하여 투명합성수지판(10)에 접착액(12)을 분무 도포한 후 목제막체(11)를 접착하는 방식이 우선적으로 고려될 수 있다.At this time, the adhesive liquid 12 may be applied to either the transparent synthetic resin plate 10 or the wooden film body 11, but the transparent synthetic resin plate 10 may be applied in consideration of the flexibility of the wooden film body 11, A method of spraying the adhesive liquid 12 on the wood film body 11 and then adhering the wood film body 11 may be preferentially considered.

수성(水性) EVA(Ethylene Vinyl Acetate copolymer) 접착액(12)인 본 발명의 접착액(12)은 유기용제와 고무 또는 수지 용질이 혼합된 통상의 유성 접착제는 물론, 다량의 수용성 수지 또는 수지 분산체가 함유된 일반 수성 접착제와 그 성상에 있어서 차이가 있는 것으로, 다량의 물이 함유되어 저점성 액상체를 형성함으로써 목제막체(11)의 조직내 용이한 침투가 가능하도록 하면서도, 소량의 톨루엔(toluene)이 첨가되어 접착면 형성 및 접착층 양생을 촉진할 수 있도록 한 것이다.The adhesive liquid 12 of the present invention, which is an aqueous ethylene-vinyl acetate copolymer (EVA) adhesive liquid 12, can be used not only as a conventional oil-based adhesive in which an organic solvent and a rubber or a resin solute are mixed, The present invention is different from the general water-based adhesive containing a sieve body in that a small amount of water is contained to form a low-viscosity liquid body, thereby allowing easy penetration into the tissues of the wood film body 11, toluene) is added to facilitate the formation of the adhesive surface and the curing of the adhesive layer.

즉, 다량의 물과 혼합된 에멀젼(emulsion) 상태의 EVA에 톨루엔을 첨가하여 유동성 및 침투성이 우수한 저점성 접착액(12)을 형성한 것으로, EVA 30중량% 내지 50중량%와, 물 45중량% 내지 65중량%와, 톨루엔 5중량% 내지 10중량%가 혼합되어 접착액(12)을 구성하게 된다.That is, toluene is added to EVA in an emulsion state mixed with a large amount of water to form a low-viscosity adhesive liquid 12 having excellent flowability and permeability. The EVA is composed of 30% by weight to 50% by weight of EVA, To 65% by weight and toluene 5% by weight to 10% by weight are mixed to constitute the adhesive liquid 12.

종래의 유성 접착제는 인체에 유해한 다량의 유기용제가 적용되어 제조 및 유통과정에서 심각한 환경오염을 유발할 수 있으나, 본 발명의 접착액(12)은 실질적 주성분이 물이라 할 수 있으므로, 유해성을 크게 저감할 수 있으며, 종래의 수성 접착제는 용제의 휘발성이 낮고 접착면의 형성이 불량한 단점이 있으나, 톨루엔이 함유된 본 발명의 접착액(12)은 접착층의 양생간 용제의 건조를 촉진할 뿐 아니라 양생 초기 접착 대상 투명합성수지판(10) 표면을 미세하게 용해하여 양호한 접착면을 형성하게 된다.Conventional oily adhesives can cause serious environmental pollution during manufacture and distribution due to the application of a large amount of organic solvent harmful to human body. However, since the adhesive liquid 12 of the present invention can be regarded as substantially a main component thereof, And the conventional aqueous adhesive has a disadvantage in that the volatility of the solvent is low and the formation of the adhesive surface is poor. However, the adhesive liquid 12 of the present invention containing toluene not only promotes the drying of the solvent during curing of the adhesive layer, The surface of the transparent synthetic resin plate 10 to be initially bonded is finely dissolved to form a good bonding surface.

또한, 종래의 수성 접착제는 용질 및 용제의 조성비가 각각 70중량% 내지 80중량% 및 20중량% 내지 30중량%로서 점성이 클 뿐 아니라 비교적 다량의 용질이 함유되어 접착후 건조시 접착면에 과도한 고형물이 형성되는 특성이 있으나, 본 발명에서는 다량의 물이 함유된 저점성 접착액(12)을 적용함으로써 접착후 과도한 고형물 형성을 억제할 수 있을 뿐 아니라 접착액(12) 도포시 목제막체(11) 조직내로 용이한 침투가 가능하다.In addition, the conventional aqueous adhesive is composed of 70% by weight to 80% by weight and 20% by weight to 30% by weight of solute and solvent, respectively, and has a relatively large viscosity and contains a relatively large amount of solute, In the present invention, by using the low-viscosity adhesive liquid 12 containing a large amount of water, it is possible to suppress the formation of excessive solids after the adhesion, 11) Easy penetration into the tissue is possible.

본 발명의 접착액(12)은 종래의 접착제에 비하여 유효 성분인 수지 용질의 함량이 상대적으로 낮으므로 접착력이 저하될 것으로 오해될 수 있으나, 접착대상물이 치밀하고 평활한 표면을 가지는 판체가 아니라, 도 3의 좌측 타원내 확대부에서와 같이, 공극비가 높고 느슨한 조직 및 불규칙한 표면을 가지는 목제막체(11)임을 감안할때, 오히려 용질이 저감된 본 발명의 저점성 접착액(12)이 목제막체(11)의 조직내 원활한 침투가 가능하고 후술할 압착프레스(30) 처리 등을 통하여 조직내 신속한 확산 및 고도로 평활한 접착면의 형성에 유리하므로, 소기의 접착력 발현에는 전혀 지장이 없게 된다.The adhesive liquid 12 of the present invention may be misunderstood to be lowered in adhesive strength because the content of the resin solute is relatively low as compared with the conventional adhesive. However, the adhesive object is not a plate having a dense and smooth surface, 3, the low viscosity adhesive liquid 12 of the present invention, in which the solute has been reduced, is inferior to the wood film 11 having a loose structure and an irregular surface, It is possible to smoothly penetrate the structure of the sieve 11 and to perform rapid spreading in the tissue and formation of a highly smooth adhesive surface through a pressing press 30 process or the like to be described later.

이렇듯, 투명합성수지판(10)에 목제막체(11)가 접착되어 투명합성수지판(10) 접착체가 완성되면, 투명합성수지판(10) 접착체를 라미네이터(20)에 투입하여, 목제막체(11) 표면 즉, 목제막체(11)의 접착면 이면에 합성수지 필름(15)을 라미네이트함으로써, 투명합성수지판(10), 목제막체(11) 및 합성수지 필름(15)이 순차적으로 적층된 투명합성수지판(10) 피복체를 구성하게 된다.When the laminating body 11 is adhered to the transparent synthetic resin plate 10 and the adhesive agent for the transparent synthetic resin plate 10 is completed, the adhesive agent for the transparent synthetic resin plate 10 is put into the laminator 20, 11, the wooden film body 11 and the synthetic resin film 15 are sequentially laminated by laminating the synthetic resin film 15 on the front surface of the wood film body 11 Thereby forming a cover body of the synthetic resin plate 10.

라미네이터(20)를 통하여 투명합성수지판(10) 피복체가 완성되면, 투명합성수지판(10) 피복체를 압착프레스(30)로 압착함으로써, 도 3의 우측 타원내 확대부에서와 같이, 목제막체(11) 조직을 압축하여 투명합성수지판(10)과 목제막체(11)간 접착면을 평활화하고 접착면내 잔류 기포를 배제하게 되는데, 이 상태를 소정 시간 유지하여 접착액(12)을 건조 및 경화시킴으로써, 도 5에서와 같이 견고하게 일체화되고 미려한 문양이 표현된 목제막체(11) 부착형 합성수지 패널이 제조된다.When the clad body of the transparent synthetic resin plate 10 is completed through the laminator 20, the clad body of the transparent synthetic resin plate 10 is squeezed by the pressing press 30, (11) is compressed to smooth the bonding surface between the transparent synthetic resin plate (10) and the wood film body (11) to eliminate residual bubbles in the bonding surface. The bonding liquid (12) By curing, a wood-film-body-attachable synthetic resin panel 11, which is firmly integrated and has a beautiful pattern as shown in Fig. 5, is manufactured.

또한, 도 3에 도시된 바와 같이, 생산성 확보를 위하여 다수의 투명합성수지판(10) 피복체를 적층한 상태로 압착프레스(30)에 투입할 수 있는데, 이 경우 적층된 각각의 투명합성수지판(10) 피복체 사이에는 이형지(離形紙)(19)를 투입하여 압착과정에서 불필요한 접착이 발생되지 않도록 하는 것이 바람직하다.As shown in FIG. 3, in order to secure productivity, a plurality of transparent synthetic resin plates 10 can be put into a press press 30 in a laminated state. In this case, the transparent synthetic resin plates 10) It is preferable to insert a release paper 19 between the cover bodies so as to prevent unnecessary adhesion in the pressing process.

한편, 도 4는 본 발명의 변형된 실시예로서, 라미네이트 처리를 최종 단계에서 수행하는 것으로, 이를 상세히 설명하면 다음과 같다.Meanwhile, FIG. 4 is a modified embodiment of the present invention in which the lamination process is performed in the final stage, which will be described in detail as follows.

우선 도 3의 실시예에서와 같이, 도 4의 실시예 또한 투명합성수지판(10) 배면에 목제막체(11)를 접착하여 투명합성수지판(10) 접착체를 구성함으로써 개시된다.As in the embodiment of Fig. 3, the embodiment of Fig. 4 is also started by bonding the wooden film body 11 to the back surface of the transparent synthetic resin plate 10 to construct the adhesive body of the transparent synthetic resin plate 10. [

이후, 상기 투명합성수지판(10) 접착체를 압착프레스(30)로 압착함으로써 목제막체(11) 조직을 압축하여 투명합성수지판(10)과 목제막체(11)간 접착면을 평활화하고 접착면내 잔류 기포를 배제한 상태에서 접착액(12)을 건조하여 투명합성수지판(10) 압착체를 구성하는 단계가 수행되는데, 이때 도 4에 도시된 바와 같이 다수의 투명합성수지판(10) 접착체를 적층하여 압착프레스(30)에 투입하는 경우, 각각의 투명합성수지판(10) 접착체 사이에는 반드시 이형지(19)를 적층하여야 투명합성수지판(10) 접착체간 불요(不要) 접착을 방지할 수 있다.Thereafter, the bonding agent of the transparent synthetic resin plate 10 is pressed by a pressing press 30 to compress the structure of the wood film body 11 to smooth the bonding surface between the transparent synthetic resin plate 10 and the wood film body 11, The step of drying the adhesive liquid 12 in the state where the in-plane residual bubbles are excluded is carried out to form the compressed synthetic resin plate 10 pressed body. At this time, as shown in FIG. 4, It is possible to prevent unnecessary bonding between adhesive materials of the transparent synthetic resin plate 10 by stacking the release papers 19 between the adhesive materials of the respective transparent synthetic resin plates 10 .
