장식용 안전 복합유리{Safety Complex Glass for Decoration} Safety Complex Glass for Decoration             

도 1 은 본 발명에 따른 안전 장식유리.1 is a safety decorative glass according to the present invention.

도 2 는 도1의 A-A선 단면도.2 is a cross-sectional view taken along the line A-A of FIG.

*도면중 주요부분에 대한 부호의 설명** Description of the symbols for the main parts of the drawings *

1,1' : 유리층 2 : 지류1,1 ': glass layer 2: feeder

3,3' : PVB 용융접착필름 4 : 함침지3,3 ': PVB melt adhesive film 4: impregnated paper

본 발명은 수용성 잉크로 인쇄된 지류에 유리와 접착력이 우수한 폴리비닐부티랄수지(PVB)를 함침시킨 PVB 함침지를 상하 양면의 유리층과 PVB필름을 접착층으로하여 적층한 장식용 안전 복합유리에 관한 것이다.The present invention relates to a decorative safety composite glass laminated with a PVB-impregnated paper impregnated with polyvinyl butyral resin (PVB) having excellent adhesion to glass and a paper printed with a water-soluble ink by using an adhesive layer of glass layers on both upper and lower surfaces and a PVB film. .

일반적으로 유리의 일면이나 양면에 각종 무늬층을 형성하여 장식용 인조대리석을 제조하거나 유리의 일면에 인쇄층을 형성한 다음 그 인쇄층 위에 접착제로 또하나의 유리면을 접착시켜 복합유리층으로된 건축물 내외장용이나 장식용 인조대리석을 제조하는 방법에 관한 특허 및 실용신안이 많이 출원되어 등록되고 시판되고 있는 예가 많으나 그것들은 모두 접착층과 인쇄층이 취약하여 충격에 의해 파손되게되면 인쇄층과 유리층이 파편이 되어 비산되므로 인체에 엄청난 위해를 끼칠 수 있는 위험이 있고 제조공정도 유리면에 인쇄, 그 인쇄면위에 보호층, 그 보호층위에 접착층, 그 접착층위에 유리층등을 형성하는 복잡한 과정을 일일이 거쳐야하므로 많은 종류의 재료준비와 여러단계의 제조공정 과정을 거쳐야하므로 높은 재료비, 과다한 인건비, 많은 제조시간 소요등의 요인으로 제조원가가 높아지고 단시간에 양산하기가 어려운 폐단이 있었고, 파손시에 안전성 보장도 취약한 결점이 있었다.In general, a variety of patterned layers are formed on one or both sides of glass to produce decorative artificial marble, or a printing layer is formed on one side of glass, and then another glass surface is bonded on the printed layer with adhesive to form a composite glass layer. Many patents and utility models related to manufacturing exterior or decorative artificial marble have been filed and marketed. However, all of them have a weak adhesive layer and a print layer, and if they are damaged by impact, the print layer and the glass layer will have debris. There is a danger that it can cause enormous harm to the human body.Manufacturing process also has to go through the complicated process of printing on the glass surface, protective layer on the printing surface, adhesive layer on the protective layer, glass layer on the adhesive layer, etc. High material cost and excessive phosphorus due to various material preparation and several steps of manufacturing process Rain, there was a lot of preparation time consuming factors such as increasing production costs evils that are difficult to mass production in a short time with the, there were safety defects during the warranty vulnerable to damage.

본 발명은 상기한 바와같은 복합유리나 단층유리로된 인조대리석 형태의 건축물 내외장용 및 일반 장식용의 유리로된 인조대리석과 같은 복합유리의 결점을 해소하여 상하 양면의 복합유리 사이에 수용성 잉크로 인쇄된 지류에 유리와 접착력이 강한 합성수지가 함침된 함침지의 양면에 상기 지류에 함침시킨 재질과 동일 재질의 합성수지로된 상하 용융접착필름에의해 상하 양면 유리를 접착하므로서 함침지에 함침시킨 합성수지와 그 수지가 동일재질의 필름의 접착력에 의하여 유리와의 접착력이 강하여 파손시에도 유리파편이 비산되지 않고 지류에 부착된 채로 유지되게되며, 지류에는 합성수지 접착제 함침전에 수용성 인쇄잉크로 대리석무늬나 기타 장식효과를 얻을 수 있는 각종의 다양한 무늬가 인쇄되어 있으므로 그 수용성인 잉크가 함침 합성수지나 동일 재질 용융접착필름에의해 용해되거나 와해되지 않고 선명하게 유지되어 다양한 무늬에의해 다양한 장식효과를 얻을 수가 있고 함침지와 용융접착필름에의해 내열성, 내후성 및 보온성이 우수하므로 건축물 내외장용은 물론 일반 장식품 제품으로 다양하게 이용될 수 있는 장식용 안전 복합유리를 제공코저하는 것으로서 이를 첨부된 도면을 참조하면서 실례를 들어 상세히 설명하면 다음과 같다.

Even if the PVB impregnated paper (4) is passed through the PVB solution dissolved in the organic solvent, the printed layer is not dissolved or destroyed and is maintained as the original printed pattern. Invention decorative safety suit laminated on middle layer of Glass is located within the exterior panel or in number thoroughly enjoy a variety of indoor and outdoor decorative products for a variety of safety and damage to the composite glass yeoseo strength, excellent thermal insulation and cold storage building benefits.

상기 PVB용액 제조시에 PVB를 MEK 또는 TCE로만 용해하면 용해성이 약하여 쉽게 용해가 되지 않고 DMF로만 용해하면 인쇄지의 잉크를 용해할 우려가 있으므로 MEK와 TCE중 어느 하나를 DMF와 4:1의 중량비로 배합하여 사용하므로서 PVB의 용해성이 우수하면서도 상기 용제가 유기용제여서 수용성인 인쇄잉크는 용해하지 않는 특징이 있으므로 무늬가 인쇄된 함침지(4)를 PVB용액에 통과시키드라도 선명한 인쇄층을 유지하게되고 특히 상기 용제중 TCE는 난연성이어서 화재의 위험에도 견딜 수 있는 특징이 있다.When the PVB solution is prepared by dissolving PVB only with MEK or TCE, the solubility is weak so that it is not easily dissolved. When dissolving only with DMF, the ink of printing paper may be dissolved. As it is used in combination, the PVB has excellent solubility but the solvent is organic solvent, so the printing ink which is water soluble is not dissolved. Therefore, even if the printed impregnated paper 4 is passed through the PVB solution, a clear printing layer is maintained. In particular, the TCE of the solvent is characterized by being flame retardant to withstand the risk of fire.

또한 PVB를 유기용제 전체중량에 대하여 10~15wt% 첨가하는 것은 그 범위내에서 PVB가 가장 빠른시간에 쉽게 용해되고 그 이하에서는 용해성이 느리고 그 이상에서는 농도가 약하여 지류에 대한 PVB의 함침력이 약한 결점(적게 함침)이 있기 때문이며, 60~70℃의 가열온도와 30~40분간의 가열시간 역시 그 범위이하에서는 용해속도가 늦고 그 범위 이상에서는 완전 용해이전에 용제가 과량으로 휘발되어 용해력이 약해지게 된다.In addition, the addition of 10-15 wt% of PVB to the total weight of the organic solvent is easy to dissolve PVB in the fastest time within that range, and the solubility below is slow and the concentration is weak at above, so that the impregnation force of PVB on paper is weak. This is because there is a flaw (less impregnation), the heating temperature of 60-70 ℃ and the heating time of 30-40 minutes also have a slow dissolution rate under the range, and the solvent is volatilized excessively before the complete dissolution at that range, so the solvent is weak. You lose.

또 오토클레이브에서의 가열시에는 상기 135~155℃의 온도와 8~15기압 및 0.5~5시간 이하에서는 가열경화속도가 너무 느리고 그 이상에서는 유리면과 인쇄층이 열에의해 손상되기 쉬우나, 상기 조건에서는 PVB 함침지(4)와 상하 유리층(1)(1')이 그 사이에 게래된 PVB필름과의 접착력에 의하여 가장 효과적으로 단시간 에 접착되게 된다.When heating in an autoclave, the heat curing rate is too slow at temperatures of 135 to 155 ° C., 8 to 15 atm, and 0.5 to 5 hours or less, and above the glass surface and the printed layer are easily damaged by heat. The PVB impregnated paper 4 and the upper and lower glass layers 1, 1 'are most effectively adhered in a short time by the adhesion force between the PVB film introduced therebetween.

이상과 같은 본 발명 장식용 안전복합유리는 지류(2)에 PVB가 함침된 함침지(4)를 양면 유리층(1)(1') 사이에 적층된 용융접착필름(3)(3')에의해 용융접착되도록 적층하였으므로 함침지(4)에 다양하게 인쇄된 무늬에의해 인조대리석이나 기타 다양한 건축물 내외장 및 기타 장식품으로 이용할 수 있어서 용도가 다양한 효과가 있고, PVB가 유리와의 접착력이 우수하여 충격에의해 파괴되드라도 파편이 비산되지 않으므로 안전하게 사용할 수 있는 효과가 있으며, 제조공정이 간편하고 재료가 복잡하지 않아 저렴한 원가로 단시간에 양산할 수 있는 효과가 있다.As described above, the decorative safety composite glass of the present invention includes a sheet of impregnated paper 4 impregnated with PVB on the two-sided glass layer 1, 1 'to a molten adhesive film 3, 3'. Since it is laminated to melt-bonded, it can be used as artificial marble or other various building interior and exterior and other ornaments by various printed patterns on impregnated paper (4), and it has various effects, and PVB has excellent adhesion with glass. Debris is not scattered even if it is destroyed by impact, so it can be used safely. The manufacturing process is simple and the material is not complicated, so it can be mass-produced in a short time at low cost.
