양면 거울을 갖는 안전 접합유리 및 그 제조방법{LAMINATED GLASS HAVING SAFETY DOUBLE SIDE MIRROR AND MANUFACTURE METHOD THEREOF}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a safety laminated glass having a double-

본 발명은, 양면 거울을 갖는 안전 접합유리 및 그 제조방법에 관한 것으로, 보다 상세하게는, 양쪽의 투명유리 사이에 양면거울용 시트를 배치하고, 양쪽의 투명유리를 접합함으로써, 유리의 안전성을 확보하면서도 양면거울의 실용성을 제공할 수 있는 양면 거울을 갖는 안전 접합유리 및 그 제조방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a safety bonded glass having a double-sided mirror and a manufacturing method thereof, and more particularly, to a safety bonded glass having both- The present invention also relates to a safety bonded glass having a double-sided mirror capable of providing practicality of a double-sided mirror while ensuring safety.

일반적으로 접합유리란 두 장 이상의 판유리 사이에 투명하면서도 접착력이 강한 폴리비닐부틸랄(PVB)소재의 접합필름을 융착시켜 접합한 유리를 말한다.Generally, a laminated glass is a laminated glass obtained by fusing and bonding a polyvinyl butyral (PVB) laminated film having a high transparency and high adhesive strength between two or more glass plates.

이러한 접합유리는 외부의 충격에 대한 흡수력이 우수하여 쉽게 파손되지 않고, 설령 판유리가 파손된다 하더라도 접합필름이 파손된 판유리의 비산을 방지하며, 물체의 관통이 쉽지 않아 도난을 방지할 수 있기 때문에 기존 일반 강화유리를 대체하여 건축자재, 산업용 및 기타 용도로 사용되고 있다.Such a laminated glass is excellent in absorption ability against external impact and is not easily broken. Even if the laminated glass is broken, the laminated glass prevents scattering of the laminated plate glass. Also, since the penetration of the object is difficult, It is used for building materials, industrial and other purposes as an alternative to ordinary tempered glass.

이러한 접합유리와 관련하여, 대한민국 공개특허 제10-2012-0066007호에는 제1, 제2 접합 유리 구성 부재와, 상기 제1, 제2 접합 유리 구성 부재의 사이에 끼워 넣어진 중간막을 구비하되, 접합 유리용 중간막이 차열층과, 제1 자외선 차폐층을 구비하며, 상기 차열층이 열가소성 수지와, 차열 입자와, 프탈로시아닌 화합물, 나프탈로시아닌 화합물 및 안트라시아닌화합물 중 적어도 1종의 성분을 함유하고, 상기 제1 자외선 차폐층이 열가소성수지와, 자외선 차폐제를 함유하는 것을 특징으로 하는 접합 유리가 개시되어 있다.In connection with such a laminated glass, Korean Patent Laid-Open No. 10-2012-0066007 discloses a laminated glass having first and second laminated glass constituent members and an interlayer sandwiched between the first and second laminated glass constituent members, Wherein the interlayer for laminated glass comprises a heat insulating layer and a first ultraviolet shielding layer, wherein the heat insulating layer contains at least one of thermoplastic resin, heat shielding particles, phthalocyanine compound, naphthalocyanine compound and anthracene compound , And the first ultraviolet shielding layer contains a thermoplastic resin and an ultraviolet shielding agent.

최근에는 유리로 이루어지는 샤워부스의 경우에 안전성을 확보하기 위하여 전술한 바와 같은 구조의 접합유리를 사용하고 있다. In recent years, in order to ensure safety in the case of a shower booth made of glass, a laminated glass having the above-described structure is used.

그러나, 이러한 접합유리는 안전성은 확보될 수 있었으나 그 이외의 기능을 기대할 수 없었다. 예를 들면, 샤워부스에는 거울이 구비되어야 했으나, 접합유리에는 거울 기능이 구비되어 있지 않았기 때문에 거울을 별도로 부착해야 하는 문제점이 있었고, 접합유리의 일부분을 반투명 또는 불투명으로 구성하기 위해서 별도의 반투명 또는 불투명 재질의 시트지를 부착해야 하는 불편함이 있었던 것이다.However, such a bonded glass could secure safety, but other functions could not be expected. For example, a mirror must be provided in the shower booth. However, since the mirror glass is not provided in the mirror glass, there is a problem that a mirror must be attached separately. In order to make a part of the mirror glass translucent or opaque, There was an inconvenience to attach a sheet of opaque material.

As shown in Figs. 1 and 3, a safety bonded glass 10 having a double-sided mirror according to the present invention has a first adhesive sheet 30 laminated on a surface of a first glass plate 20, Aluminum vacuum deposition is performed on both surfaces or one side of a sheet of transparent polyester (PET) having a thickness of 0.05-0.15 mm on the surface of the sheet 30 to form a mirror layer 42 having a thickness of 0.05-0.1 μm The second adhesive sheet 50 is laminated on the surface of the double-sided mirror member 40 and the second glass plate 60 is laminated on the surface of the second adhesive sheet 50, Bonded structure.

이와 같은 안전 접합유리(10)는, 제1,2 유리판(20,60) 사이에 양면거울부재(40)가 적층된 상태로 제1,2 유리판(20,60)가 제1,2 접착시트(30,50)에 의해 접합됨으로써 양면 거울로 사용할 수 있음은 물론, 제1,2 접착시트(30,50)에 의해 파손시에도 유리 파편이 비산되지 않는 안전성을 확보할 수 있게 된다.In the safety bonded glass 10 as described above, the first and second glass plates 20 and 60 are bonded to the first and second glass sheets 20 and 60 in a state in which the both-side mirror member 40 is laminated between the first and second glass sheets 20 and 60, The first and second adhesive sheets 30 and 50 can be used as double-sided mirrors by being joined together by the first and second adhesive sheets 30 and 50. In addition, safety can be ensured such that glass fragments are not scattered even when the first and second adhesive sheets 30 and 50 are broken.

특히, 양면거울부재(40)가 0.05 - 0.15mm의 두께를 갖는 투명한 폴리에스테르(PET : polyethyleneterephthalate)로 된 시트지의 양면 또는 어느 한 면에 알루미늄 진공증착을 실시하여 0.05 - 0.1㎛ 두께의 거울층(42)이 형성됨으로써, 양면거울부재(40)의 크기와 형상을 다양하게 구성할 수 있을 뿐만 아니라, 저렴한 비용으로 제조할 수 있다. In particular, the double-sided mirror member 40 is subjected to aluminum vacuum deposition on both sides or one side of a sheet made of transparent polyethylene (PET) having a thickness of 0.05 to 0.15 mm to form a mirror layer 42 are formed, the size and shape of the double-sided mirror member 40 can be variously configured, and the manufacturing cost can be reduced.

이러한 양면 거울을 갖는 안전 접합유리 제조방법을 설명하기로 한다. A method of manufacturing a safety bonded glass having such a double-sided mirror will now be described.

. 양면거울부재 제조단계(S1,S2). The double-sided mirror member manufacturing step (S1, S2)

0.05 - 0.15mm의 두께를 갖는 투명한 폴리에스테르(PET)로 된 시트지의 양면 또는 어느 한 면에 알루미늄 진공증착을 실시하여 0.05 - 0.1㎛ 두께의 거울층(42)을 형성하고, 거울층(42)이 형성된 시트지를 선택된 형상으로 컷팅하여 양면거울부재(40)를 제조한다. 이때, 거울층(42)은, 시트지의 양면이나 어느 한 면에 형성될 수 있는 것으로, 본 실시예에서는 한 면에만 형성된 것을 기준으로 설명한다. 이와 같이, 거울층(42)이 시트지의 면에만 형성되어도 시트지가 투명하므로 양쪽에서 거울층(42)을 볼 수 있다. Aluminum is vacuum-deposited on both sides or one side of a sheet made of transparent polyester (PET) having a thickness of 0.05 - 0.15 mm to form a mirror layer 42 having a thickness of 0.05 - 0.1 탆, The double-sided mirror member 40 is manufactured by cutting the formed sheet paper into a selected shape. At this time, the mirror layer 42 may be formed on both sides or one side of the sheet, and in this embodiment, the mirror layer 42 is formed on only one side. Thus, even if the mirror layer 42 is formed only on the surface of the sheet, the mirror layer 42 can be seen from both sides because the sheet is transparent.

한편, 투명한 폴리에스테르(PET)로 된 시트지에 거울층(42)을 형성하는 과정은 다음과 같다. Meanwhile, the process of forming the mirror layer 42 on a sheet of transparent polyester (PET) is as follows.

먼저, 진공챔버 내부에 투명한 폴리에스테르(PET)로 된 시트지를 배치하고, 진공챔버의 내부에서 알루미늄을 가열하면 알루미늄이 증발하면서 증발분자가 발생되며, 증발분자를 증기온도보다 저온인 기본재(시트지)의 표면에 부착시키면 시트지의 표면에서 증기가 응축되어 박막, 즉 알루미늄으로 된 거울층(42)이 형성되는 것이다. 이러한 거울층(42)을 이루는 박막은 0.05 - 0.1㎛ 두께를 갖는다. 한편, 진공증착시간은 대략 8-10초이다. 여기서 진공증착시간을 10초 이상으로 하게 되면 거울층(42)의 두께가 0.1㎛ 이상이 되어 알루미늄의 과다 소모 문제가 발생되고, 8초 이만으로 하게 되면, 거울층(42)의 두께가 0.05㎛ 이하로 형성되어 너무 얇게 되므로 8-10초 사이에서 진공증착을 실시하여 거울층(42)의 두께를 0.05 - 0.1㎛로 형성하는 것이 바람직하다.First, a sheet of transparent polyester (PET) is placed inside a vacuum chamber, and when aluminum is heated in the vacuum chamber, evaporation of aluminum occurs and evaporation molecules are generated in the base material ), The vapor is condensed on the surface of the sheet paper to form a thin film, that is, a mirror layer 42 made of aluminum. The thin film constituting the mirror layer 42 has a thickness of 0.05 - 0.1 탆. On the other hand, the vacuum deposition time is approximately 8-10 seconds. If the vacuum deposition time is set to 10 seconds or more, the thickness of the mirror layer 42 becomes 0.1 mu m or more and the problem of excessive consumption of aluminum occurs. When the vacuum deposition time is shortened to 8 seconds, the thickness of the mirror layer 42 becomes 0.05 mu m The thickness of the mirror layer 42 is preferably in the range of 0.05 to 0.1 占 퐉.

그리고, 폴리에스테르(PET)로 된 시트지의 두께를 0.05mm 이하로 형성하면 형태성이 떨어져 취급이 곤란하고, 0.15mm 이상의 두께로 형성하면 중량이 증가하여 제조비용이 상승하고, 안전 접합유리의 전체 두께가 두꺼워져 취급이 곤란하게 되는 문제가 발생되므로 바람직하게는 0.1mm의 두께로 형성한다. If the thickness of the sheet made of polyester (PET) is set to 0.05 mm or less, it is difficult to handle because of the lack of formability. If the thickness is made 0.15 mm or more, the weight increases and the manufacturing cost increases. The thickness becomes thick and the handling becomes difficult. Therefore, the thickness is preferably 0.1 mm.

이와 같이, 알루미늄 진공증착도금 공정으로 폴리에스테르(PET)로 된 시트지의 한 면에 거울층(42)이 형성되면, 시트지를 선택된 형상으로 컷팅하여 양면거울부재(40)를 완성한다. 양면거울부재(40)는, 도 4 내지 도 7에 도시된 바와 같이 매우 다양한 크기와 형상으로 컷팅되어 사용될 수 있다. 즉 롤러에 감긴 양면거울부재(40)를 프레스 컷팅 금형으로 한장씩 컷팅하는 것이다. As described above, when the mirror layer 42 is formed on one side of the sheet made of polyester (PET) by the aluminum vacuum vapor deposition process, the sheet is cut into a selected shape to complete the double-sided mirror member 40. The double-sided mirror member 40 can be cut and used in a wide variety of sizes and shapes, as shown in Figs. That is, the double-sided mirror member 40 wound on the roller is cut one by one into a press-cutting mold.

. 예열처리 단계(S3). The preheating process step (S3)

전술한 양면거울부재(40)의 제조가 완료되면, 반투명 또는 투명한 제1 유리판(50)과 제2 유리판(60)을 예열 오븐(도시되지 않음)에서 50 - 80℃로 예열처리한다. When the above-described production of the double-sided mirror member 40 is completed, the semitransparent or transparent first glass plate 50 and the second glass plate 60 are preheated to 50 - 80 캜 in a preheating oven (not shown).

이러한 예열처리 공정은, 제1,2 유리판(20,60)을 예열 오븐으로 예열하여 제1,2 접착시트(30,50)의 접착이 용이하게 이루어지도록 하기 위한 것이다. 즉, 제1,2 접착시트(30,50)에 의해 제1,2 유리판(20,60)이 접착될 때, 제1,2 접착시트(30,50)의 접착성을 높이기 위한 것이다.The preheating process is for preheating the first and second glass plates 20 and 60 with a preheating oven so that the first and second adhesive sheets 30 and 50 can be easily adhered. That is, the first and second adhesive sheets 30 and 50 are intended to increase the adhesiveness of the first and second adhesive sheets 30 and 50 when the first and second glass sheets 20 and 60 are adhered by the first and second adhesive sheets 30 and 50.

. 제1 접착시트 적층단계(S4). The first adhesive sheet laminating step (S4)

제1 접착시트(30)를 적층하는 단계는, 예열 오븐에 의해 예열된 제1 유리판(20)의 표면에 제1 접착시트(30)를 적층시키는 공정이다. 이 공정에서, 제1 접착시트(30)를 제1 유리판(20)에 적층시킬 때 제1 접착시트(30)와 제1 유리판(20) 사이에 공기층이 형성되지 않도록 한다. 만약 공기층이 형성될 경우에 제1 접착시트(30)의 접착력이 약화될 수 있다. 이를 위해서, 제1 유리판(20)의 표면 한 쪽에 제1 접착시트(30)를 접착시킨 후 가압 로울러를 이용하여 제1 접작시트(30)를 순차적으로 가압하면서 전체를 접착시킨다. The step of laminating the first adhesive sheet 30 is a step of laminating the first adhesive sheet 30 on the surface of the first glass plate 20 preheated by the preheating oven. In this process, when the first adhesive sheet 30 is laminated on the first glass sheet 20, an air layer is not formed between the first adhesive sheet 30 and the first glass sheet 20. If the air layer is formed, the adhesive strength of the first adhesive sheet 30 can be weakened. To this end, the first adhesive sheet 30 is adhered to one surface of the first glass plate 20, and then the entire first adhesive sheet 30 is pressed while sequentially pressing the first adhesive sheet 30 using a pressure roller.

이러한 제1 접착시트(30)는 제1 유리판(20)과 양면거울부재(40)를 결합시키기 위한 것이다.The first adhesive sheet 30 is for joining the first glass plate 20 and the double-sided mirror member 40 together.

여기서, 제1,2 접착시트(30,50)는 폴리비닐부티랄(PVB : Polyvinylbutyral)로 이루어진다. 폴리비닐부티랄은, 폴리비닐알코올에 산 촉매하에서 부틸알데히드를 반응시켜서 합성되는 수지로서, 유리, 금속, 플라스틱, 목재, 피혁 등의 접착용으로 사용된다. Here, the first and second adhesive sheets 30 and 50 are made of polyvinyl butyral (PVB). Polyvinylbutyral is a resin synthesized by reacting polyvinyl alcohol with butylaldehyde under an acid catalyst, and is used for adhesion to glass, metal, plastic, wood, leather and the like.

. 양면거울부재 적층단계(S4). The double-sided mirror member laminating step (S4)

양면거울부재(40)를 적층시키는 단계는, 제1 접착시트(30)가 제1 유리판(20)에 적층되어 가 접착된 상태에서, 제1 접착시트(30)의 표면에 거울층(42)을 구비한 양면거울부재(40)를 적층시키는 것이다. The step of laminating the double-sided mirror member 40 is performed by stacking the mirror layer 42 on the surface of the first adhesive sheet 30 in a state in which the first adhesive sheet 30 is laminated and adhered to the first glass sheet 20, Sided mirror member 40 having the above-described structure.

본 실시예에서 양면거울부재(40)는, 폴리에스테르(PET)로 된 시트지의 양면또는 일면에 알루미늄 진공증착에 의해 거울층(42)이 형성된 것을 설명하였으나, 이에 국한되는 것은 아니고, 알루미늄 양면거울시트, 스테인레스 거울 또는 아크릴 거울로 이루어질 수 있다. In the present embodiment, the double-sided mirror member 40 has been described in which the mirror layer 42 is formed by aluminum vacuum deposition on both sides or one side of a sheet made of polyester (PET), but the present invention is not limited to this, A sheet, a stainless steel mirror, or an acrylic mirror.

. 제2 접착시트 적층단계(S4). The second adhesive sheet laminating step (S4)

When the double-sided mirror member 40 is laminated on the surface of the first adhesive sheet 30 in the above-described process, the second adhesive sheet 50 is laminated on the surface of the double-sided mirror member 40.

제2 접착시트(50)는 제2 유리판(60)과 양면거울부재(40)를 결합시키기 위한 공정이다. The second adhesive sheet 50 is a process for bonding the second glass plate 60 and the double-sided mirror member 40 together.

전술한 제1,2 접착시트(30,50)는 다양한 두께로 이루어질 수 있으나, 본 실시예에서는 0.38t의 두께로 이루어진 것을 기준으로 설명한다. Although the first and second adhesive sheets 30 and 50 may have various thicknesses, the thickness of the first and second adhesive sheets 30 and 50 is 0.38 t in the present embodiment.

. 제2 유리판 적층단계(S4). The second glass sheet laminating step (S4)

양면거울부재(40)에 제2 접착시트(50)가 적층되면, 제2 접착시트(50)의 표면에 예열된 제2 유리판(60)을 적층시킨다. When the second adhesive sheet 50 is laminated on the both-side mirror member 40, the second glass sheet 60 preheated on the surface of the second adhesive sheet 50 is laminated.

. 완성단계(S5). The completion step (S5)

전술한 과정으로 제1 접착시트(30)를 제1 유리판(20)에 적층하고, 제1 접착시트(30)의 표면에 양면거울부재(40)를 적층하며, 양면거울부재(40)의 표면에 제2 접착시트(50)를 적층한 후 제2 접착시트(50)의 표면에 제2 유리판(60)을 적층하는 단계(S3)가 완료되면, 서로 적층된 제1 유리판(20), 제1 접착시트(30), 양면거울부재(40), 제2 접착시트(50) 및 제2 유리판(60)을 결합하여 일체화시킨다. The first adhesive sheet 30 is laminated on the first glass plate 20 and the double-sided mirror member 40 is laminated on the surface of the first adhesive sheet 30, The step of stacking the second adhesive sheet 50 on the second adhesive sheet 50 after the step of stacking the second adhesive sheet 50 on the first adhesive sheet 50 is completed, The first adhesive sheet 30, the double-sided mirror member 40, the second adhesive sheet 50, and the second glass plate 60 are combined and integrated.

즉, 서로 적층되어 가 결합된 상태의 안전 접합유리를 가열로(도시되지 않음) 내부로 투입하여 소정온도로 가열함과 동시에 양쪽의 제1 유리판(20)과 제2 유리판(60)을 서로 마주보는 방향으로 가압하여 결합한다.That is, the safety bonded glass in a state of being stacked and joined to each other is injected into a heating furnace (not shown) and heated to a predetermined temperature, and both the first glass plate 20 and the second glass plate 60 face each other Press in the viewing direction to join.

이를 보다 구체적으로 설명한다. This will be described in more detail.

먼저, 제1 유리판(30)과 제2 유리판(60) 사이에, 제1 접착시트(30)와 양면거울부재(40) 및 제2 접착시트(50)가 차례로 적층된 상태에서 가열로(도시되지 않음) 내부로 투입하여 110 - 150℃로 가열하면서 제1 유리판(20)과 제2 유리판(60)을 서로 마주보는 방향으로 가압하여 제1,2 접착시트(30,50)의 용융으로 제1 유리판(20)과 양면거울부재(40) 및 제2 유리판(60)을 접합시키는 가열 접합단계를 수행한다. First, a first adhesive sheet 30, a double-sided mirror member 40, and a second adhesive sheet 50 are sequentially stacked between a first glass plate 30 and a second glass plate 60, And the first glass plate 20 and the second glass plate 60 are pressed in mutually opposing directions while being heated at 110 to 150 ° C. to melt the first and second adhesive sheets 30 and 50 1, a heat bonding step of bonding the glass plate 20 to the double-sided mirror member 40 and the second glass plate 60 is performed.

이와 같이, 제1 유리판(30)과 제2 유리판(60) 사이에, 제1 접착시트(30)와 양면거울부재(40) 및 제2 접착시트(50)가 차례로 적층된 상태에서 제1,2 유리판(20.60)을 가열로에 투입하여 제1,2 접착시트(30,50)를 용융시키고 프레스 장치를 이용하여 제1,2 유리판(20,60)을 서로 마주보는 방향으로 가압함으로써 제1 유리판(30)과 양면거울부재(40) 및 제2 유리판(60)은 서로 견고하게 접착되어 일체화가 된다. The first adhesive sheet 30, the double-sided mirror member 40 and the second adhesive sheet 50 are stacked in this order between the first glass sheet 30 and the second glass sheet 60, 2 glass plate 20.60 is put in a heating furnace to melt the first and second adhesive sheets 30 and 50 and the first and second glass plates 20 and 60 are pressed in directions opposite to each other by using a press apparatus, The glass plate 30, the double-sided mirror member 40 and the second glass plate 60 are firmly adhered to each other and integrated.

이어서, 가열 접합단계의 진행으로 제1,2 유리판(20,60)이 양면거울부재(40)를 사이에 두고 서로 접합이 되면, 안전 접합유리(10)를 상온에서 서서히 냉각하는 냉각단계를 수행한다. 이때, 가열되었던 안전 접합유리(10)를 냉각수에 넣거나 냉각수를 뿌려 금속하게 냉각시키게 되면 제1,2 유리판(20,60)이 급격한 온도변화에 따른 수축 작용에 따라 파손될 수 있으므로, 반드시 상온에서 서서히 냉각시킨다. Next, when the first and second glass plates 20 and 60 are bonded to each other with the double-sided mirror member 40 interposed therebetween by the progress of the heating and bonding step, a cooling step of slowly cooling the safety bonded glass 10 at room temperature is performed do. At this time, if the safety bonded glass 10 that has been heated is put into the cooling water or sprinkled with cooling water to cool the metal, the first and second glass plates 20 and 60 may be broken due to the shrinking action according to the rapid temperature change. Therefore, And cooled.

이와 같이, 제1,2 유리판(20,60) 사이에, 양면거울부재(40)가 배치된 상태에서, 제1 유리판(20)과 양면거울부재(40) 및 제2 유리판(60)이 제1,2 접착시트(30,50)에 의해 접착됨으로써, 양면거울을 갖는 안전 접합유리(10)의 제조가 완료된다. As described above, the first glass plate 20, the double-sided mirror member 40 and the second glass plate 60 are disposed between the first and second glass plates 20, 1 and 2 adhesive sheets 30 and 50, thereby completing the production of the safety bonded glass 10 having both-side mirrors.

전술한 과정으로 제조된 양면 거울을 갖는 안전 접합유리(10)는, 제1,2 유리판(20,60) 사이에 양면거울부재(40)가 배치되어 제1,2 유리판(20,60)과 일체화됨으로써 안전 접합유리(10)의 양쪽에서 거울의 기능을 사용할 수 있음은 물론, 제1 유리판(20)과 양면거울부재(40) 및 제2 유리판(60)이 제1,2 접착시트(30,50)에 의해 접착되어 일체화되어 있기 때문에, 안전 접합유리(10)가 파손되더라도 유리 파편이 비산되지 않게 되어 안전성이 확보될 수 있다. The safety bonded glass 10 having a double-sided mirror manufactured by the above-described process has a double-sided mirror member 40 disposed between the first and second glass plates 20 and 60 to form the first and second glass plates 20 and 60, The first glass plate 20 and the double-sided mirror member 40 and the second glass plate 60 can be used as the first and second adhesive sheets 30 , 50, so that even if the safety bonded glass 10 is broken, the glass fragments are not scattered, and safety can be ensured.

특히, 최근에 욕실의 샤워부스의 중간 벽체나 도어를 강화 유리 등으로 구성하는 경우에, 유리 벽체가 충격이나 자파현상(자연파손현상)에 의해 파손되면서, 날카로운 유리파면이 비산되어 사용자의 안전을 위협하고 있었으나, 본 발명에 의한 양면거울부재(40)를 구비한 안전 접합유리(10)를 샤워부스의 벽체로 사용함으로써 유리 벽체의 안전성을 확보할 수 있게 된다. Especially, when the middle wall of the shower booth of the bathroom and the door are made of tempered glass or the like, the glass wall is damaged by impact or natural phenomenon (natural breakage phenomenon), sharp glass wavefront is scattered, The safety of the glass wall can be ensured by using the safety bonded glass 10 provided with the double-sided mirror member 40 according to the present invention as a wall of the shower booth.

즉, 본 발명에 따른 안전 접합유리(10)는, 양면거울부재(40)의 양쪽 면에 제1,2 유리판(20,60)이 제1,2 접착시트(30,50)에 의해 접착되어 일체화됨으로써, 충격에 의한 파손시에 유리 파편이 제1,2 접착시트(30,50)에 의해 접착된 상태를 유지하게 되므로 비산되지 않게 되고, 따라서 유리 벽체의 파손에 의해 안전사고를 미연에 방지할 수 있게 된다. That is, in the safety bonded glass 10 according to the present invention, the first and second glass plates 20 and 60 are bonded to both sides of the double-sided mirror member 40 by the first and second adhesive sheets 30 and 50 As a result, the glass pieces are held by the first and second adhesive sheets 30, 50 at the time of breakage due to the impact, so that they are not scattered. Therefore, the glass wall is prevented from being damaged .

그리고, 제1,2 유리판(20,60) 사이에 배치되는 양면거울부재(40)가 폴리에스테르(PET)로 된 시트지로 이루어짐으로써, 제1,2 접착시트(30,50)와 더불어 안전 접합유리(10)가 충격에 견딜 수 있는 강성을 향상시킬 수 있게 된다. Since the double-sided mirror member 40 disposed between the first and second glass plates 20 and 60 is made of a sheet made of polyester (PET), the first and second adhesive sheets 30 and 50, The rigidity of the glass 10 that can withstand the impact can be improved.
