본 발명은 입체소재가 내장된 아크릴 패널 제조방법 및 이에 의해 제조된 아크릴 패널에 관한 것이다. 더욱 상세하게는 내부에 장식용 입체소재를 넣고 액상의 아크릴수지를 주입하여 형성하는 입체소재가 내장된 아크릴 패널 제조방법에 있어서, 장식용 소재 주변에 기포나 플로우 마크가 발생되지 않고 투명하고 맑게 아크릴 패널이 형성되어 품질을 높일 수 있는 입체소재가 내장된 아크릴 패널 제조방법 및 이에 의해 제조된 아크릴 패널에 관한 것이다.The present invention relates to a method for producing an acrylic panel incorporating a three-dimensional material and an acrylic panel produced thereby. More specifically, in the method of manufacturing an acrylic panel in which a three-dimensional material is formed by inserting a decorative three-dimensional material therein and injecting a liquid acrylic resin, the acrylic panel is transparent and clear without bubbles or flow marks generated around the decorative material. The present invention relates to a method for manufacturing an acrylic panel having a three-dimensional material formed therein and improving quality thereof, and an acrylic panel manufactured thereby.

통상적으로 아크릴수지는 메틸 메타크릴레이트(MMA; Methyl Methacrylate)를 주원료로 하는 열가소성 합성수지로서, 유리보다 우수한 광투과율, 내열성, 파괴강도 및 가공성을 가지고 있어서, 판 형태로 성형되어서 간판, 조명, 진열장 등에 이용되며, 최근에는 항공기, 자동차, 대형수족관 또는 실내 인테리어 등에 다양하게 사용되고 있다.Typically, acrylic resins are thermoplastic synthetic resins containing methyl methacrylate (MMA) as the main raw material, and have excellent light transmittance, heat resistance, breaking strength, and workability than glass, and are formed in a plate shape to signboards, lighting, showcases, etc. In recent years, it is used in a variety of aircraft, cars, large aquariums or interiors.

이러한 아크릴수지로 이루어진 아크릴 패널은 일반적으로 성형방법에 따라 가압롤러를 통해 아크릴 패널을 가공하는 압출판과, 액상의 아크릴수지를 한 쌍의 금형판 사이에 주입하고 이를 냉각시켜 성형하는 캐스팅판으로 구분된다. The acrylic panel made of such acrylic resin is generally divided into an extrusion plate for processing the acrylic panel through a pressure roller according to a molding method, and a casting plate for injecting liquid acrylic resin between a pair of mold plates and cooling the molded sheet. do.

압출판은 대량생산은 가능하나 강도가 떨어지는 단점이 있고, 캐스팅판은 생산성은 떨어지나 강도의 저하가 없어 고급제품에 사용되고 있다. 이와 같은 아크릴 패널은 통상 그 표면이 매끄러우며 단일색상을 가지므로, 고급스러운 제품을 형성하기 위한 장식성을 부가할 필요가 있게 된다.Extruded plate is capable of mass production, but has a disadvantage of low strength, and casting plate is used in high-end products because of low productivity but no decrease in strength. Such acrylic panels are usually smooth on the surface and have a single color, so it is necessary to add decorative properties to form a high-quality product.

먼저, 압출판의 장식효과를 향상시키기 위해서는 프레스의 표면에 음양각의 무늬를 만들거나, 두 장의 아크릴 패널 사이에 얇은 박판의 장식용 소재나 인쇄물 등의 입체감이 없는 평면의 소재를 놓고 프레스를 사용하여 열을 가하면서 가압하여 두 장의 판을 접합시키게 된다.First, in order to improve the decorative effect of the extruded plate, make an embossed pattern on the surface of the press, or place a flat material without a three-dimensional effect such as a thin sheet of decorative material or printed material between the two acrylic panels and heat it using a press. Pressing while pressing will join the two sheets together.

그러나 이러한 방법에 의해 가공된 아크릴 패널은 강도가 약하여 접착면에 물리적인 힘을 가했을 때 떨어지거나, 두꺼운 판의 경우에는 접착면에 열전달이 어려워 제작에 어려움이 많았고, 특히 입체감이 큰 장식용 소재는 아크릴 패널 사이에 넣고 가압할 경우 압착되어 입체감을 나타낼 수 없는 문제점이 있었다.However, the acrylic panel processed by this method has a weak strength, so when the physical force is applied to the adhesive surface, the acrylic panel is hard to produce, or in the case of a thick plate, it is difficult to produce heat transfer to the adhesive surface. There was a problem in that it is not possible to represent the three-dimensional feeling when pressed between the panels when pressed.

다음으로, 캐스팅판의 장식효과를 향상시키기 위해서는 아크릴판에 입체무늬를 만들거나, 금형으로 사용하는 유리판에 장식용 입체소재를 고정시킨 후 금형에 용융상태의 아크릴수지를 주입하여 냉각시키는 방법이 사용된다.Next, in order to improve the decorative effect of the casting plate, a method of making a three-dimensional pattern on an acrylic plate or fixing a decorative three-dimensional material on a glass plate used as a mold and then injecting an acrylic resin in a molten state into the mold and cooling is used. .

그러나 입체소재를 내장시켜 형성하는 아크릴판의 경우에는 장식용 입체소재의 주위에 기포가 발생되거나, 물결무늬와 같은 플로우 마크(Flow Mark)가 발생되어 인테리어 제품의 가치를 현저히 떨어뜨리는 치명적인 문제점이 있었다.However, in the case of an acrylic plate formed by embedding a three-dimensional material, bubbles are generated around a decorative three-dimensional material, or a flow mark such as a wave pattern is generated, which causes a fatal problem that significantly lowers the value of the interior product.

본 발명은 전술한 문제점을 해결하기 위해 안출된 것으로, 내부에 장식용 입체소재를 넣고 액상의 아크릴수지를 주입하여 형성하는 입체소재가 내장된 아크릴 패널 제조방법에 있어서, 장식용 소재 주변에 기포나 플로우 마크가 발생되지 않고 투명하고 맑게 아크릴 패널이 형성되어 품질을 높일 수 있는 입체소재가 내장된 아크릴 패널 제조방법 및 이에 의해 제조된 아크릴 패널을 제공하는 데에 그 목적이 있다.The present invention has been made to solve the above-described problems, in the method of manufacturing an acrylic panel with a built-in three-dimensional material formed by putting a decorative three-dimensional material therein and injecting a liquid acrylic resin, bubbles or flow marks around the decorative material It is an object of the present invention to provide a method for producing an acrylic panel with a built-in three-dimensional material that can be formed transparent and clear acrylic panel without increasing the quality and the acrylic panel produced thereby.

본 발명에 의한 입체소재가 내장된 아크릴 패널 제조방법에서는 대략 두께가 2~3 mm 이상되는 입체감있는 장식용 입체소재(230)를 금형판(210) 내부에 고정하고 이 금형판(210)을 가압 가열하는 1차중합반응 단계(S120)와, 이후 대기압으로 압력을 낮추고 가열하는 2차중합반응 단계(S140)를 거침으로써, 아크릴 패널의 내부에 장착된 장식용 입체소재(230)의 주변에 기포나 플로우 마크가 발생되지 않고 투명하고 맑은 상태를 유지하여 장식용 소재의 입체감이 살아나게 되는 특징이 있다.In the method of manufacturing an acrylic panel incorporating a three-dimensional material according to the present invention, the three-dimensional decorative three-dimensional material 230 having a thickness of approximately 2 to 3 mm or more is fixed in the mold plate 210 and the mold plate 210 is pressurized and heated. By passing through the first polymerization step (S120) and the second polymerization step (S140) to lower the pressure to atmospheric pressure and then heated, bubbles or flow around the decorative three-dimensional material 230 mounted inside the acrylic panel There is a feature that the three-dimensional appearance of the decorative material is alive by maintaining a clear and clear state without generating a mark.

여기서, 입체소재(230)는 꽃, 조개, 돌, 물고기, 곤충, 나뭇잎 등과 같은 자연소재와, 동전, 기념패, 메달 등과 같은 금속소재, 손톱, 머리카락, 뼈 등과 같은 인체소재, 사진, 옷감 등과 같은 인쇄물이 이용된다.Here, the three-dimensional material 230 is a natural material such as flowers, shells, stones, fish, insects, leaves, metal materials such as coins, commemorative plaques, medals, human body materials such as nails, hair, bones, photos, cloth, etc. Prints are used.

금형판(210)은 주로 유리판이 사용되며 상측과 하측의 한쌍으로 이루어지는데, 이들 금형판(210)의 사이에는 아크릴 패널을 장식하는 장식용 입체소재(230)가 삽입되고 이 주위에 씰링을 담당하는 가스킷(220)이 둘러싸여 설치된다.Mold plate 210 is mainly used for the glass plate and consists of a pair of upper and lower sides, between the mold plate 210 is a decorative three-dimensional material 230 for decorating the acrylic panel is inserted and responsible for sealing around it The gasket 220 is surrounded and installed.

아크릴수지는 액상으로 금형판에 주입전 개시제가 첨가되어 일정 이상의 점도를 유지하는 예비중합을 하여 사용하며 금형판에 주입시 아크릴수지에 첨가되어 주입되는데, 이에 사용되는 개시제는 모노머를 중합시키는 AIBN(아조비스이소부틸로니트릴) 등과 같은 라디칼 개시제로 산업 전반에서 사용되는 것이므로 이하 상세한 설명은 생략하기로 한다.Acrylic resin is used as pre-polymerization to maintain the viscosity above a certain amount by adding the initiator before injection into the mold plate in the liquid phase and is added to the acrylic resin when injected into the mold plate, and the initiator used is AIBN (polymerization monomer) Since a radical initiator such as azobisisobutylonitrile) is used throughout the industry, the following detailed description will be omitted.

입체소재(230)는 도 2a에 도시된 것처럼 금형판(210) 위에 입체소재(230)를 아크릴수지를 이용해 부착하여 고정하거나, 도 2b에 도시된 것처럼 금형판(210) 위에 소정의 두께를 갖는 아크릴판(235)을 놓고 이 아크릴판(235)에 입체소재(230)를 아크릴수지를 이용해 부착하여 고정하게 된다.The three-dimensional material 230 is fixed by attaching the three-dimensional material 230 on the mold plate 210 using an acrylic resin as shown in Figure 2a, or has a predetermined thickness on the mold plate 210 as shown in Figure 2b The acrylic plate 235 is placed and the three-dimensional material 230 is attached to the acrylic plate 235 by fixing with acrylic resin.

아크릴수지 주입 단계(S110)는 금형판(210) 내부에 장식용 입체소재(230)를 직접 고정시키거나 아크릴을 이용해 고정시키고 이 입체소재의 주위에 제작할 아크릴 패널의 크기를 감안하여 가스킷(220)을 설치하고, 상측과 하측으로 이루어진 한쌍의 금형판(210) 내부에 액상의 아크릴수지를 주입하여 클램프(215)로 금형판(210)을 고정시키게 된다.Acrylic resin injection step (S110) is fixed to the decorative three-dimensional material 230 directly in the mold plate 210 or fixed using acrylic and considering the size of the acrylic panel to be manufactured around the three-dimensional material gasket 220 The mold plate 210 is fixed by the clamp 215 by injecting a liquid acrylic resin into the pair of mold plates 210 formed of upper and lower sides.

고정된 금형판(210)은 거치대(240) 등을 이용하여 가압 가열 탱크(250)에 넣고, 금형판이 잠길정도로 물을 채운 상태에서 액상의 아크릴수지를 아크릴판으로 경화시키는 1차중합반응 단계(S120)를 거치게 된다.The fixed mold plate 210 is placed in a pressurized heating tank 250 by using a holder 240, and the first polymerization reaction step of curing the liquid acrylic resin into an acrylic plate while the mold plate is filled with water so that the mold plate is locked. It goes through S120).

1차중합반응 단계(S120)는 12~20 시간 정도 지속되는데, 이 때 압력을 3~10 kg/㎠ 로, 온도를 30~70 ℃로 가압 가열함으로써 아크릴수지가 내부에서 발열반응과 점도 상승으로 인해 비중이 증가되며 부피가 감소하여 수축이 일어날 때, 장식용 입체소재(230)의 주위에 기포나 플로우 마크가 발생되는 것을 방지하게 된다.The first polymerization reaction step (S120) lasts about 12 to 20 hours, when the pressure is heated to 3 to 10 kg / cm 2 and the temperature to 30 to 70 ° C., so that the acrylic resin is exothermic and the viscosity rises inside. Due to the increase in specific gravity and decrease in volume, shrinkage occurs to prevent bubbles or flow marks from being generated around the decorative three-dimensional material 230.

여기서, 1차중합반응 단계(S120)는 압력을 4~6 kg/㎠ 로, 온도를 50~60 ℃로 가압 가열하여 12~14 시간동안 유지하는 단계를 포함함으로써, 장식용 입체소재(230)의 주위에 기포나 플로우 마크가 발생되는 것을 최소화하게 된다.Here, the first polymerization step (S120) is a pressure of 4 ~ 6 kg / ㎠, by pressing the temperature to 50 ~ 60 ℃ by heating for 12 to 14 hours, by including the step of the decorative three-dimensional material 230 Minimization of bubbles or flow marks around is generated.

다만, 이는 일반적으로 사용되는 입체소재가 내장된 인테리어용 아크릴 패널의 두께가 20~25mm 내외인 경우를 말하는 것으로 반드시 이에 한정되는 것은 아니며, 아크릴 패널의 두께가 30mm 이상인 특수한 경우에는 두께가 커질수록 1차중합반응 단계의 소요시간은 늘어날 수도 있고, 아크릴 패널의 두께가 20mm 이하인 특수한 경우에는 두께가 작아질수록 1차중합반응 단계의 소요시간이 줄어들수도 있을 것이다.However, this generally refers to a case in which the thickness of the interior acrylic panel having a built-in three-dimensional material is about 20 to 25 mm, and is not necessarily limited thereto. In a special case where the thickness of the acrylic panel is 30 mm or more, the larger the thickness, 1 The time required for the polymerization step may be increased, and in special cases where the thickness of the acrylic panel is 20 mm or less, the time required for the first polymerization step may be reduced as the thickness decreases.

1차중합반응 단계(S120)를 거친 가압 가열 탱크(250)의 내부에서 물을 빼내고 압력을 대기압으로 낮추는 감압 단계(S130)를 거쳐서, 2차중합반응 단계(S140)로 진행된다.After the water is removed from the inside of the pressurized heating tank 250 that passed through the first polymerization reaction step S120 and the pressure is reduced to atmospheric pressure, the process proceeds to the second polymerization step S140.

2차중합반응 단계(S140)는 감압 단계(S130)를 거친 한쌍의 금형판(210)을 가압 가열 탱크(250)에서 온도를 80~130 ℃로 가열하여 1~5 시간 유지하게 되는데, 이렇게 2차중합반응 단계(S140)를 거침으로써 1차중합반응 단계(S120)에서 중합반응시 잔존하는 아크릴수지 모노머를 최대한 반응시키게 되어, 아크릴 패널의 물성 을 향상시키게 된다. In the secondary polymerization reaction step (S140), a pair of mold plates 210, which have undergone the depressurization step (S130), are heated in a pressurized heating tank 250 at a temperature of 80 to 130 ° C. and maintained for 1 to 5 hours. By passing through the secondary polymerization step (S140), the acrylic resin monomer remaining during the polymerization reaction in the primary polymerization step (S120) is allowed to react as much as possible, thereby improving physical properties of the acrylic panel.

여기서 2차중합반응 단계(S140)는 대기압하에서 90~110 ℃로 가열하여 2~4 시간동안 유지하는 단계를 포함함으로써 잔존하는 미반응된 아크릴수지 모노머를 최소화하게 된다.Here, the second polymerization step (S140) includes a step of heating at 90 to 110 ° C. under atmospheric pressure for 2 to 4 hours to minimize remaining unreacted acrylic resin monomer.

2차중합반응 단계(S140)를 거친 한쌍의 금형판(210)은 이를 냉각시키고 금형판(210)을 제거하는 탈형 단계(S150)를 거치고, 제조할 크기에 맞추어 절단하면서 가스킷(220)을 제거하게 되면 입체소재가 내장된 아크릴 패널이 완성되게 된다.The pair of mold plates 210, which have undergone the second polymerization reaction step (S140), undergoes a demoulding step (S150) for cooling them and removing the mold plates 210, and removes the gasket 220 while cutting to a size to be manufactured. This will complete the acrylic panel embedded with a three-dimensional material.

이렇게 완성된 아크릴 패널은 세면대, 욕조, 변기 등과 같은 욕실 및 화장실의 인테리어 용품으로 사용되거나, 열쇠고리, 목걸이, 휴대폰 걸이, 메달, 기념패 등과 같은 각종 기념품으로 사용될 수 있다.The finished acrylic panel may be used as interior items in bathrooms and toilets, such as sinks, bathtubs, toilets, or various souvenirs such as key chains, necklaces, cell phone hangers, medals, and memorial plaques.

상술한 바와 같은 본 발명에 의하면 내부에 장식용 입체소재를 넣고 액상의 아크릴수지를 주입하여 형성하는 입체소재가 내장된 아크릴 패널 제조방법에 있어서, 장식용 소재 주변에 기포나 플로우 마크가 발생되지 않고 투명하고 맑게 아크릴 패널이 형성되어 품질을 높일 수 있는 효과가 있게 된다.According to the present invention as described above, in the method of manufacturing an acrylic panel in which a three-dimensional material is formed by inserting a decorative three-dimensional material therein and injecting a liquid acrylic resin therein, bubbles or flow marks are not generated around the decorative material and are transparent.
