도시된 바와 같이 통상적인 접합유리는 충격에 대한 흡수력이 우수하여 쉽게 파손되지 않고, 설령 판유리가 파손되더라도 접합필름에 의해 파손된 판유리의 조각이 비산되는 것을 방지하는 기능을 가진다. As shown in the drawing, conventional laminated glass has an excellent absorbing force against impact and is not easily broken, and even if the glass is broken, the laminated glass has a function of preventing the pieces of broken glass from being scattered by the laminated film.

또한, 물체의 관통이 쉽지 않아 도난을 방지할 수 있는 조건으로 인해 기존 일반 강화유리를 대체하여 건축자재, 산업용 및 기타 다양한 용도로 사용되고 있다. In addition, due to the conditions that can not easily penetrate the object to prevent theft, it is being used for building materials, industrial and other various uses in place of the existing general tempered glass.

그러나 접합유리는 안전성을 확보할 수 있었으나, 그 이외의 기능을 기대할 수 없는 단점을 가진다. However, the laminated glass was able to secure the safety, but has the disadvantage that other functions can not be expected.

상기한 문제점을 해결하기 위하여 종래에도 접합유리에 거울과 같은 기능을 갖도록 하는 기술이 제안된 바 있으나, 그 다양한 소재가 요구될 뿐만 아니라 그로 인해 제조과정이 상당히 번거롭고 불편한 단점을 가진다. In order to solve the above problems, there has been conventionally proposed a technique of having a mirror-like function in laminated glass, but not only the various materials are required but also the manufacturing process is quite cumbersome and inconvenient.

본 발명은 최소한의 간단한 접착 또는 접합 소재가 요구됨은 물론 그로 인한 제조공정이 간단하게 이루어짐과 아울러 필요로 하는 다양한 형상의 양면 거울이 형성되도록 하는 데 있다. The present invention provides a simple double-sided mirror having a variety of shapes required as well as a simple manufacturing process is required, as well as the resulting simple process.

본 발명에 따른 접합유리의 제조과정은 다음과 같다. The manufacturing process of the laminated glass according to the present invention is as follows.

먼저, 공지된 방식에 의해 필요한 용도에 맞는 크기로 절단된 2~8㎜의 두께를 가지는 한 쌍의 유리(10)를 통상적인 방식에 의해 표면으로 오염된 부분을 제거하도록 세척하는 단계(S1)를 수행한다. 상기 세척이 완료된 후에는 표면으로 물 등을 포함하는 세정제가 남아있지 않도록 통상적인 건조과정을 세정제가 남아있지 않도록 한다. First, washing the pair of glass 10 having a thickness of 2 to 8 mm cut to a size suitable for the required use by a known method to remove the contaminated portion to the surface by a conventional method (S1). Perform After the cleaning is completed, a conventional drying process is performed so that no cleaning agent remains, so that no cleaning agent containing water or the like remains on the surface.

그런 다음 상기 세척된 하나의 유리(10) 표면에 형성하고자 하는 거울 디자인(12) 부분을 제외한 필름층(20)을 형성하는 단계(S2)를 행한다. Then, a step (S2) of forming the film layer 20 except for the portion of the mirror design 12 to be formed on the surface of the cleaned glass 10 is performed.

상기에서, 거울 디자인 부분은 적용되는 대상에 따라 적정한 디자인 선택하여 적용할 수 있어, 적용되는 대상에 가장 이상적인 디자인을 적용할 수 있는 것이다. In the above, the mirror design portion can be applied by selecting the appropriate design according to the object to be applied, it is possible to apply the most ideal design to the object to be applied.

여기서, 상기 필름층(20)은 대략 30~100㎛ 두께를 가지는 통상적인 PET 시트를 부착하거나 공지된 인쇄기법에 의해 실리콘 잉크를 인쇄하는 것 중의 어느 하나이다. 상기 PET 시트는 상기한 범위 내의 두께 중 생산성이 우수한 리무브(remove) 점착 50㎛ 필름이 가장 이상적인 것이나, 일반적인 시트를 사용하여도 무방하다. 허나 일반적은 점착 필름을 사용시에는 점착제로 인한 불량률이 높을 수 있는 관계로, 리무브(remove) 점착 50㎛ 필름을 사용하는 것이 바람직하다. Here, the film layer 20 is any one of attaching a conventional PET sheet having a thickness of about 30 ~ 100㎛ or printing a silicon ink by a known printing technique. The PET sheet is ideally a 50 μm film of a removable adhesive having excellent productivity among the thicknesses within the above range, but a general sheet may be used. However, when using a pressure-sensitive adhesive film in general, since the defect rate due to the pressure-sensitive adhesive may be high, it is preferable to use a 50 μm remove adhesive film.

아울러, 상기 PET 시트에 형성되는 거울 디자인(12) 부분은 그 PET 시트에 통상적인 방식에 의해 거울 디자인(12)을 마킹(marking) 후 그 마킹된 부분을 통상적인 커팅칼을 이용하여 제거하거나 통상적인 인쇄기법에 의해 실리콘 잉크를 인쇄 시 거울 디자인(12) 부분을 제외한 부분을 인쇄하는 것 중의 어느 하나이다. In addition, the portion of the mirror design 12 formed on the PET sheet may be marked or removed using a conventional cutting knife after marking the mirror design 12 in a manner conventional to the PET sheet. It is any one of printing parts except the mirror design 12 part when printing a silicon ink by the printing method.

그리고 나서 상기 거울 디자인(12) 부분을 포함하여 필름층(20) 전체 면에 공지된 알루미늄 진공증착(30) 하는 단계(S3)를 행한다. Thereafter, a step S3 is performed for the known aluminum vacuum deposition 30 on the entire surface of the film layer 20 including the mirror design 12 portion.

상기에서, 알루미늄 진공증착(30)은 통상적인 진공챔버 내에서의 진공증착 하는 방식보다는 불량률이 현저히 적은 컨베이어형 진공증착 방식을 적용하여 진공증착 하는 것이 바람직하다. 특히, 알루미늄 진공증착에서의 주요 불량은 기포, 증착 불량, 거울과 유리 라인 불량 등이 발생하는바, 이를 최소화할 수 있도록 컨베이어형 진공증착 방식을 적용하는 것이 바람직하다. In the above, the aluminum vacuum deposition 30 is preferably vacuum-deposited by applying a conveyor-type vacuum deposition method with a significantly lower defect rate than a vacuum deposition method in a conventional vacuum chamber. In particular, the main defects in the vacuum deposition of aluminum, such as bubbles, deposition failures, mirror and glass line failures occur, it is preferable to apply a conveyor-type vacuum deposition method to minimize this.

또한, 알루미늄 진공증착은 통상적인 0.05~01㎛ 두께를 가진다. In addition, aluminum vacuum deposition has a typical thickness of 0.05 ~ 01㎛.

그 후 상기 거울 디자인(12) 부분에 알루미늄 진공증착(30) 된 양면 거울층(40)을 제외한 알루미늄 진공증착 된 필름층(20)을 통상적인 방식에 의해 제거하는 단계(S4)를 행한다. Thereafter, the step S4 of removing the aluminum vacuum-deposited film layer 20 except for the double-sided mirror layer 40 on which the aluminum vacuum deposition 30 is carried out on the mirror design 12 is performed (S4).

다시 말해서, 상기 알루미늄 진공증착 된 부분은 양면 거울로 사용할 수 있는 부분이다. In other words, the aluminum vacuum deposited portion can be used as a double-sided mirror.

마지막으로, 상기 필름층이 제거되어 알루미늄 진공증착 된 양면 거울층(40) 측에 통상적인 접착시트(50)를 올려놓은 후 세척된 다른 하나의 유리를 올려 1차와 2차에 거쳐 접합하는 단계(S5)를 수행함에 따라 접합유리(1)의 모든 제조과정이 완료된다. Finally, after the film layer is removed, a conventional adhesive sheet 50 is placed on the aluminum vacuum-deposited double-sided mirror layer 40 side, and then the other glass is cleaned and bonded through the first and second steps. By carrying out (S5) all the manufacturing process of the laminated glass (1) is completed.

상기에서, 접착시트(50)는 통상적인 PVB, EVA 또는 UV resin 중의 어느 하나이며, 0.38~1.2㎜의 두께를 가지는 것이 바람직하며, 그 중에서도 PVB를 적용하는 것이 바람직하다. 상기 PVB는 폴리비닐알코올에 산 촉매하에서 부틸알데히드를 반응시켜서 합성되는 수지로, 유리, 금속, 플라스틱, 목재, 피혁 등의 접착용으로 사용되는 것이므로 가정 적정하다 할 것이다. In the above, the adhesive sheet 50 is any one of the conventional PVB, EVA or UV resin, preferably has a thickness of 0.38 ~ 1.2mm, and among them, it is preferable to apply PVB. The PVB is a resin synthesized by reacting polyvinyl alcohol with butylaldehyde under an acid catalyst, and is suitable for home, because it is used for adhesion of glass, metal, plastic, wood, leather, and the like.

상기 접착시트가 0.38㎜ 이하일 경우에는 기포 발생 확률이 높고, 접착시트의 레벨링 문제로 인하여 고른 접착이 이루어지지 않아 불량률이 높은 단점을 가지며, 접착시트가 1.2㎜ 이상일 경우에는 접착필름의 가격이 비싸므로 경제성이 떨어지며 제조시간이 상대적으로 길어져 생산 효율성이 떨어지는 관계로, 상기한 범위 내의 접착시트를 적용하는 것이 바람직하다. When the adhesive sheet is less than 0.38㎜, the probability of bubble generation is high, and evenly adhesion is not made due to the leveling problem of the adhesive sheet, and the defect rate is high. When the adhesive sheet is more than 1.2㎜, the adhesive film is expensive. It is preferable to apply the adhesive sheet within the above range because the economic efficiency is low and the production time is relatively long and the production efficiency is low.

상기에서, 1차와 2차에 거쳐 접합하는 방식을 종래 통상적인 접합유리를 제조시 접합하는 방식과 대응소유한 것으로, 상기 1차 접합은 180~200℃에서 30~300초의 열 건조에 의해 이루어지며, 상기 2차 접합은 100~300℃의 진공상태에서 3~5시간 통상적인 오토클레이브(autoclave) 내에서 가압에 의해 이루어진다. In the above, the method of laminating through the primary and the secondary is corresponding to the method of laminating at the time of manufacturing conventional conventional laminated glass, the primary lamination is made by thermal drying of 30 to 300 seconds at 180 ~ 200 ℃ The secondary bonding is carried out by pressurization in a conventional autoclave for 3 to 5 hours in a vacuum at 100 to 300 ° C.

상기 1차 접합에서의 상기 온도와 시간 이하 또는 이상일 때에는 PVB 접착시트의 융점에 도달하지 못하여 접착력이 현저히 떨어지거나 기포 발생 및 레벨링이 나오지 못하여 불량률이 높아지며, 물리 및 화학적인 신뢰성을 갖춘 제품을 제조할 수 없는 것이므로 상기한 조건이 적정하다. When the temperature and time in the primary bonding is less than or equal to or more than the melting point of the PVB adhesive sheet does not reach the adhesive strength is significantly reduced or the bubble generation and leveling does not come out to increase the defective rate, and to manufacture a product having physical and chemical reliability The above conditions are appropriate because it is impossible.

또한, 상기 2차 접합 역시 상기 온도와 시간 이하일 때, 전력 소비는 물론 제조시간이 걸어지므로 생산효율이 매우 낮아지고 생산원가도 높아지며, 온도와 시간이 이상일 때에도 접착시트의 화학적 물성이 변화하여 접착력 및 내구성이 떨어지는 관계로, 상기한 범위 내의 조건이 적정하다 할 것이다. In addition, when the secondary junction is also below the temperature and time, the power consumption as well as the manufacturing time is long, the production efficiency is very low and the production cost is also high, even when the temperature and time is more than the change in the chemical properties of the adhesive sheet and the adhesive strength and Since the durability is inferior, the conditions within the above range will be appropriate.

상기와 같이 본 발명은 접합유리(1)를 제조하는 과정에서 그 접합유리가 가지는 안전성을 확보하는 기능 이외에 양면 거울(1A)을 형성하는 기술적 구성 또한 복잡하거나 번거로운 것이 아니라 간단하면서 신속하게 이루어질 수 있을 뿐만 아니라 특히 최소한의 소재로 원하는 형태의 양면 거울을 형성할 수 있는 것이다. As described above, the present invention, in addition to the function of securing the safety of the laminated glass in the process of manufacturing the laminated glass 1, the technical configuration of forming the double-sided mirror (1A) can also be made quickly and simply, not complicated or cumbersome. In addition, it is possible to form a double-sided mirror of the desired shape, especially with a minimum of material.

그로 인해 생산성을 높일 수 있을 뿐만 아니라 특히 우수한 품질을 가지는 제품을 제공할 수 있는 것이다. As a result, it is possible not only to increase productivity, but also to provide a product having particularly high quality.
