Description

칼라무늬 인조대리석 및 그 제조방법{ARTIFICIAL COLOR MARBLE AND A PROCESS FOR PREPARATION THEREOF}Collar pattern artificial marble and its manufacturing method {ARTIFICIAL COLOR MARBLE AND A PROCESS FOR PREPARATION THEREOF}

본 발명은 투명 유리나 투명 플라스틱판을 기판으로 하여 그 배면에 각종의 다양한 칼라무늬를 인쇄하여 정면에서 보아 천연대리석과 같은 무늬를 현출하면서 박리되지 않고 변색되지 않도록한 건축물 내외장용의 칼라무늬 인조 대리석 및 그 제조방법에 관한 것이다.The present invention prints a variety of color patterns on the back of the transparent glass or transparent plastic plate as a substrate, and the color pattern marble for interior and exterior of the building to prevent the peeling and discoloration while exhibiting the same pattern as the natural marble from the front and It relates to a manufacturing method.

종래에는 유리나 투명플라스틱을 이용한 칼라무늬 인조 대리석을 제조하려면 먼저 그라비아 인쇄나 실크 스크린 인쇄기법으로 각종 색상의 대리석 무늬가 인쇄된 무늬지를 유리면이나 투명플라스틱면의 일면(배면)에 접착제로 부착하여 타면(정면)에서 보아 천연대리석과 같은 효과를 내게하였으나 이 경우에 투명 유리면이나 투명플라스틱면으로된 기판을 통하여 현출되는 대리석 무늬층이 짧은 기간내에 태양광선의 자외선에 의하여 노화되어 변색되거나 탈색되므로 천연 대리석 무늬를 상실하게 되고 따라서 인조 대리석임이 금방 노출되게 되는 결점이 있었고 또한 이때 인쇄된 무늬지가 태양광선이나 수분의 영향으로 쉽게 유리면으로 부터 박리되기 쉬워서 내구성이 약한 결점도 있었다.Conventionally, in order to manufacture color-patterned artificial marble using glass or transparent plastic, first, a gravure printed or silk screen printing technique is used to attach a patterned paper on which a marble pattern of various colors is printed with an adhesive on one surface (back) of the glass surface or transparent plastic surface. From the front), it gave the same effect as the natural marble, but in this case, the marble pattern layer that appears through the substrate made of transparent glass or transparent plastic surface is discolored or discolored by ultraviolet rays of sunlight within a short period of time. There was a flaw that the artificial marble was quickly exposed, and the printed pattern was easily peeled off from the glass surface under the influence of sunlight or moisture, and thus had a weak durability.

상기한바와같은 투명기판을 이용한 칼라무늬 인조 대리석의 결점을 개선하기위하여 각종 색상의 인쇄잉크를 이용하여 유리면에 직접 실크 스크린 인쇄등의 방법으로 인쇄하여 인조 대리석을 제조하고져 시도한바 있으나, 이 경우에 유리속으로 인쇄 잉크가 흡수되지 못하기 때문에 여러가지 색상을 인쇄시에 인쇄된 망점(網点)들이 경화되기전에 퍼져서 인근의 다른 색상과 혼합되어 칼라무늬의 선명도가 약하고 섬세하지 못한 결점이 있게되어 천연대리석과 같은 효과를 얻을 수가 없었다.In order to improve the shortcomings of the color-patterned artificial marble using the transparent substrate as described above, the artificial marble was manufactured by printing silkscreen printing directly on the glass surface using printing inks of various colors. Because the printing ink is not absorbed into the glass, printed dots are printed before hardening in various colors and mixed with other nearby colors, resulting in a weak and unclear color pattern. Could not achieve the same effect as marble.

특히 종래 유리면에 칼라무늬를 인쇄하는 기술은 에나멜에 안료를 첨가하여 스크린 인쇄하거나 초자(유리)안료를 텔핀유에 교반하여 스크린 인쇄한 후 가열로에서 섭씨 450°∼-500°에서 서서히 가열하여 인쇄층이 유리에 고착되게 하였으나 이때 다색 인쇄의 경우에는 한가지색을 인쇄할때마다 가열경화과정을 거쳐야 하므로 매우 비 생산적이고 비능률적인 결점이 있었다.In particular, the technique of printing a color pattern on the glass surface is screen printing by adding a pigment to the enamel or screen printing by stirring the glass (glass) pigment with telpine oil, and then gradually heating the heating layer at 450 ° to -500 ° in a heating furnace. In the case of multi-color printing, heat curing was performed every time one color was printed, which was very unproductive and inefficient.

이상과 같은 종래의 유리를 이용한 인조대리석의 제조방법에서의 결점을 해소하기 위하여 최근에는 유리면에 인쇄된 인쇄잉크가 속성 건조되고 다양한 무늬를 인쇄하더라도 망점의 손상이 없이 각종 색상의 경계면이 뚜렸하고 선명하게 나타나면서 태양광선의 자외선에 의해서 변색이나 변질이 잘되지 않는 인조대리석을 얻기위하여, 솔벤트 나프타, 에틸-3-에톡시 프로피오네이트 및 사이크로헥사논으로 된 유기 혼합용제에 아크릴 수지와 비닐수지의 혼합물에 필요한 색상의 안료를 적량 혼합한 것을 인쇄 잉크로 하여 투명유리의 배면에 통상의 실크스크린 인쇄기법으로 다양한 색상을 차례로 인쇄한 후 그 인쇄층배면에 인쇄층 보호제 겸 자외선 흡수제를 도포하여 칼라무늬 인조대리석을 제조한 바 있으나, 이경우에는 아크릴수지와 비닐수지를 용해하기위해 용제를 여러가지 혼합해야하므로 공정이 복잡해지고 제조원가가 높아지게되는데 특히 용제이면서 변색방지를위해 안정제로서 사이크로헥산을 첨가하고 잉크의 속건을 위해 에틸-3-에톡시-프로피오네이트를 첨가하며, 순수용제용으로 솔벤트나프타를 별도로 각각 첨가해야하므로 제조공정의 복잡성과 재료비의 고가로 인한 비경제적인 결점이 있었다. 뿐만아니라 상기와 같은 인쇄 잉크 재료만으로는 접착력이 약하여 폴리 카보네이트나 아클릴 수지판과 같은 투명 플라스틱판을 기판으로 하여 인쇄무늬층을 인쇄하게되면 인쇄층이 인쇄된 대로 유지되지 못하기 때문에 기판을 유리로만 사용해야하는 결점이 있었고 자외선에 대한 안정성도 약하여 단시일내에 칼라무늬가 변색되어 천연무늬대리석과 같은 효과를 상실하게되는 결점이 있었다.In order to solve the shortcomings in the conventional method of manufacturing artificial marble using glass as described above, even though the printing ink printed on the glass surface has been rapidly dried and printed various patterns, the boundary of various colors is thick and clear without damaging the dots. In order to obtain artificial marble which is not easily discolored or altered by ultraviolet rays of sunlight, acrylic resin and vinyl resin in an organic mixed solvent of solvent naphtha, ethyl-3-ethoxy propionate and cyclohexanone A mixture of pigments of the required color in a proper amount is used as a printing ink, and various colors are sequentially printed on the back of the transparent glass by a conventional silkscreen printing method, and then a printing layer protective agent and an ultraviolet absorber are applied to the back of the printing layer. Patterned artificial marble was manufactured, but in this case acrylic resin and vinyl resin Since the solvent must be mixed in order to dissolve, the process is complicated and the manufacturing cost is increased. Especially, it is a solvent and adds cyclohexane as a stabilizer to prevent discoloration, and ethyl-3-ethoxy-propionate is added for quick drying of the ink. As solvent naphtha must be added separately for pure solvents, there was an uneconomical defect due to the complexity of the manufacturing process and the high cost of materials. In addition, only the printing ink material as described above has a weak adhesive force, and when the printed pattern layer is printed using a transparent plastic plate such as polycarbonate or an acrylic resin plate, the printed layer cannot be maintained as printed, so the substrate is made of glass only. There was a flaw that had to be used, and the stability against UV rays was also weak, so that the color pattern was discolored in a short time, so that the effect such as natural pattern marble was lost.

본 발명은 상기한 바와 같은 투명유리나 투명 플라스틱판을 기판으로 하여 거기에 각종 칼라 인쇄잉크로 인쇄한 인조 대리석을 제조함에 있어서, 인쇄잉크층의 취약한 접착력으로 인하여 인쇄과정에서나 인쇄후 표면 보호층 코팅 직전까지의 취급시에 인쇄층이 박리 및 훼손되는 결점을 해소하기 위하여 기판의 배면에 먼저 자외선차단겸 자외선 흡수용 프라이머층(하도층)을 형성한 다음 그배면에 자외선 차단용 합성수지로된 인쇄잉크로 칼라무늬 인쇄층을 형성하여 가열 경화시키므로서 인쇄층이 기판으로부터 쉽게 박리되지 않고 완전하게 고착되게하고 자외선 흡수 및 차단 물질에 의하여 칼라무늬 인쇄층이 자외선에의해 노출되지 않아 변색이나 변질이 일어나지 않게하며 인쇄층 배면에는 먼저 인쇄층 보호막을 도포한 다음 그 배면에 유연하거나 견고한 보호피막을 다시 형성하므로서 인쇄층을 완벽하게 보호하면서 기판이 깨지드라도 파편이 흩어지거나 비산되지 않고 부착된채로 유지되게 하여 공해를 일으키지 않게하는 칼라무늬 인조 대리석 및 그 제조방법을 제공코저 하는 것으로서 이를 실예를 들어 상세히 설명하면 다음과 같다.The present invention, in the manufacture of artificial marble printed with a variety of color printing ink on the transparent glass or transparent plastic plate as a substrate thereon, due to the weak adhesion of the printing ink layer in the printing process or immediately after the surface protective layer coating after printing In order to alleviate the defect that the printed layer is peeled off and damaged during the processing up to the first, a UV blocking and UV absorbing primer layer (undercoat) is formed on the back side of the substrate, and then a printing ink made of synthetic resin for blocking the UV rays is formed on the back side. By forming and curing the color pattern printing layer, the print layer is completely adhered to the substrate without being easily peeled off, and the color pattern printing layer is not exposed to ultraviolet rays by UV absorbing and blocking material so that discoloration or alteration does not occur. On the back of the printed layer, a protective layer of print layer is first applied and then flexible on the back. It provides a patterned artificial marble and its manufacturing method that completely protects the printed layer by forming a solid protective film and keeps the debris from being scattered or scattered even if the substrate is broken so as not to cause pollution. This will be described in detail by way of examples.

이상과 같이 구성되는 본 발명 칼라무늬 인조대리석은 기판인 유리나 플라스틱판의 배면에 자외선 방지제인 PVDF및 자외선 흡수제인 DP-P-MBDMT가 첨가된 프라이머(3)가 도포되어 있어서 그 배면에 칼라색상으로 인쇄된 인쇄층(2)의 노화, 변색등 변질을 완벽하게 보호 예방할 수가 있으면서 인쇄층의 색상과 색상끼리의 경계면을 선명하게 해주는 효과가 있고, 또 상기 프라이머에 내포된 실리카나 규사분은 열에의해 기판(1)에 가열 융착되어 있으므로 인쇄층(2)과 기판을 잡고 있어서 인쇄층이 기판으로부터 박리되는 것을 예방하게 되고 상기 인쇄층(2)배면에는 유연한 폴리우레탄수지로된 인쇄층 보호막(4)이 도포되어 있어서 인쇄층의 박리나 훼손을 완벽하게 보호하게되며 상기 인쇄층 보호막(4)배면에는 FRP나, 유리섬유판에 유연한 폴리우레탄수지나 견고한 에폭시수지를 도포한것이 피복되어 있기 때문에 유리나 플라스틱으로된 기판이 파손되어 파편이 발생하드라도 떨어져서 흩어지거나 비산되는 일이 없이 그 파편들을 잡고 원래의 상태대로 유지하게 되어 공해 방지 효과가 있게 되는 것이다.The colored patterned artificial marble of the present invention constituted as described above is coated with a primer (3) to which PVDF, which is a UV-protective agent, and DP-P-MBDMT, which is an ultraviolet absorber, is applied to the rear surface of a glass or plastic plate, which is a substrate. While it is possible to completely prevent and prevent deterioration such as aging and discoloration of the printed printed layer 2, it is effective to sharpen the interface between the colors and colors of the printed layer, and silica or silica powder contained in the primer is heated by heat. Since it is heated and fused to the board | substrate 1, the printing layer 2 and the board | substrate are hold | maintained, and the printing layer is prevented from peeling from a board | substrate, The printed layer protective film 4 which consists of a flexible polyurethane resin on the back of the said print layer 2 is carried out. The coating layer is completely protected from peeling or damage of the printing layer, and the back surface of the printing layer protection film 4 is made of flexible polyurethane resin or silk on FRP or glass fiber board.

상기에서 보강충전제의 입자크기나 첨가량은 상기 주어진 범위가 가장바람직하며 그 범위 이하이면 기판에 고착되는 강도가 약해지고 그 이상이면 프라이머층이 너무 거칠어서 인쇄층이 균일하지 못한 결점이 생기게되며, 흡수제의 양 역시 상기 주어진 범위이하가 되면 자외선 흡수효과가 약하여 인쇄층이 변색되기 쉽고 그 범위 이상이 되면 오히려 인쇄층의 선명성을 저해 하게되는 결점이 있게 된다. 인쇄층(2)과 프라이머층(3)이 형성된 기판(1)을 터널로에서 가열하는 온도는 120℃이하이면 경화속도가 너무 느리고 250℃이상이되면 인쇄면이 소결되어 타버리거나 변색 및 변질되는 결과가 오게 된다.The particle size or the amount of the reinforcing filler in the above range is most preferred, and if the above range is less than that, the strength of the reinforcing filler is weakened. If the amount is also below the given range, the ultraviolet absorbing effect is weak, so that the printed layer is easily discolored. When the substrate 1 on which the print layer 2 and the primer layer 3 are formed is heated in a tunnel furnace, the curing speed is too slow when the temperature is 120 ° C. or lower, and when the temperature is 250 ° C. or higher, the printed surface is sintered, burned or discolored and deteriorated. Will come.
