Description

다기능성 접합유리 제조방법{Manufacturing method of Multi-functional laminated glass }Technical Field [0001] The present invention relates to a multi-functional laminated glass,

본 발명은 다기능성 접합유리 제조방법에 관한 것으로, 보다 상세하게는 유리부재의 표면에 단열, 자외선 차단, 적외선 차단, 빛반사 및 착색 등의 기능을 수행하는 코팅층을 각각 형성하거나 혹은 다기능의 단일 코팅층을 형성하고 이들 코팅층을 접합시트 등으로 접합시키는 구조로 이루어져 각 코팅층의 다양한 기능을 조합할 수 있으며, 코팅 조성물과 폴리비닐부틸랄(PVB) 시트와의 접합 성능이 향상된 다기능성 접합유리 제조방법에 관한 것이다.
More particularly, the present invention relates to a method for manufacturing a multi-functional laminated glass, which comprises forming a coating layer on the surface of a glass member for performing functions such as heat insulation, ultraviolet ray blocking, infrared ray blocking, light reflection and coloring, And bonding these coating layers with a bonding sheet or the like to combine various functions of the respective coating layers and to improve the bonding performance between the coating composition and the polyvinyl butyral (PVB) sheet .

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 열가소성 수지와, 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.

다만, 상기 공개특허의 중간막은 오로지 접합유리 전용으로만 사용해야하는 제한이 있으며, 기 제조된 코팅 유리에 적용하는 경우 접합 성능을 확인할 수 없어 호환성이 떨어지는 문제가 있다.However, the interlayer of the above-mentioned patent has a limitation in that it is used exclusively for the bonded glass, and when it is applied to the previously manufactured coated glass, the bonding performance can not be confirmed and the compatibility is poor.

In addition, the terms described below are defined in consideration of the functions of the present invention, and these may vary depending on the intention or precedent of the user. Therefore, the definition should be based on the contents throughout this specification.

도 1은 본 발명에 따른 다기능성 접합유리를 도시하는 단면도이다.1 is a cross-sectional view showing a multi-functional laminated glass according to the present invention.

도 1은 참조하면, 본 발명에 따른 다기능성 접합유리(10)는 크게 제1유리부재(11)와, 상기 제1유리부재(11)에 접합되는 제2유리부재(15)로 이루어진다.Referring to FIG. 1, a multi-functional bonded glass 10 according to the present invention comprises a first glass member 11 and a second glass member 15 bonded to the first glass member 11.

상기 제1유리부재(11)의 상면에는 제1코팅층(12)이 형성되고, 상기 제2유리부재(15)의 하면에는 제2코팅층(14)이 형성된다.A first coating layer 12 is formed on the upper surface of the first glass member 11 and a second coating layer 14 is formed on the lower surface of the second glass member 15.

상기 제1코팅층(12) 및 제2코팅층(14)은 각각 단열, 자외선 차단, 적외선 차단, 빛반사 및 착색 등을 수행하는 것을 예시할 수 있다.Examples of the first coating layer 12 and the second coating layer 14 may include heat insulation, ultraviolet blocking, infrared blocking, light reflection, and coloring, respectively.

상기 제1코팅층(12) 및 제2코팅층(14)은 동일한 기능을 수행할 수도 있고, 서로 다른 기능을 수행할 수도 있다.The first coating layer 12 and the second coating layer 14 may perform the same function or may perform different functions.

예를 들어, 상기 제1코팅층이 자외선 차단 기능을 하는 경우, 상기 제2코팅층은 착색 기능을 수행하도록 구성할 수 있으며, 상기 제1코팅층 및 제2코팅층이 모두 자외선 차단 기능을 수행할 수도 있다.For example, when the first coating layer has an ultraviolet shielding function, the second coating layer may be configured to perform a coloring function, and both the first coating layer and the second coating layer may perform an ultraviolet shielding function.

그리고 제1코팅층 또는 제2코팅층은 2가지 기능을 수행할 수도 있는데, 이를 위해 자외선/적외선 차단과 단열 기능을 동시에 수행할 수 있는 금속산화물 분말 또는 금속 분말을 함유하는 것을 예시할 수 있다.The first coating layer or the second coating layer may perform two functions. For example, the first coating layer or the second coating layer may contain a metal oxide powder or a metal powder capable of simultaneously performing an ultraviolet / infrared ray blocking and adiabatic function.

상기 금속산화물 분말은 ATO(Antimony Tin Oxide), WO3, MoO3, AZO(Aluminium Zinc Oxide) 및 ITO(Indium Tin Oxide)인 것을 예시할 수 있다.The metal oxide powder may be ATO (Antimony Tin Oxide), WO 3 , MoO 3 , AZO (Aluminum Zinc Oxide), or ITO (Indium Tin Oxide).

상기 금속 분말은 백금 분말, 백금 분말의 표면을 실리카로 피복한 입자, 팔라듐 분말 및 팔라듐 분말의 표면을 실리카로 피복한 분말을 예시할 수 있다.The metal powder may be platinum powder, particles obtained by coating the surface of the platinum powder with silica, palladium powder and powder obtained by coating the surface of the palladium powder with silica.

상기 제1코팅층(12) 또는 제2코팅층(15)은 무기계 또는 유기계 안료 분말을 포함하는 것을 예시할 수 있다.The first coating layer 12 or the second coating layer 15 may include an inorganic or organic pigment powder.

한편, 상기 접합층(13)은 접합 시트, 예를 들어 폴리비닐부틸랄(PVB) 시트로 이루어져 열압착을 통해 상기 제1코팅층 및 제2코팅층과 밀접하게 접합된다.On the other hand, the bonding layer 13 is composed of a bonding sheet, for example, a polyvinyl butyral (PVB) sheet, and is tightly bonded to the first and second coating layers through thermocompression bonding.

따라서 상기 제1코팅층, 제2코팅층 및 폴리비닐부틸랄의 접합 성능을 향상시키는 것이 바람직한데, 이를 위해 본 발명에 따른 제1코팅층 및 제2코팅층은 코팅액과, 바인더를 포함하는 코팅 조성물로 이루어진다.Therefore, it is preferable to improve the bonding performance between the first coating layer, the second coating layer, and the polyvinyl butyral. To this end, the first coating layer and the second coating layer according to the present invention are formed of a coating composition comprising a coating liquid and a binder.

상기 코팅액은 상기 분말, 용제, 분산제로 이루어진다.The coating liquid is composed of the powder, solvent, and dispersant.

상기 바인더는 복수의 실란계 커플링제, 메톡시프로판올, 물, 에탄올, 에폭시 수지, 질산, Alkylol ammonium salt 및 Acrylate copolymer로 이루어지는 것이 바람직하다.The binder is preferably composed of a plurality of silane-based coupling agents, methoxypropanol, water, ethanol, epoxy resin, nitric acid, Alkylol ammonium salt, and acrylate copolymer.

여기서, 대한민국 등록특허 제10-1261204호에는 Tetraethoxy silane, 3-Glycidoxypropyltrimethodxy silane, 3-Methacryloxypropyltrimethodxy silane, Phenyltrimethoxy silane, Octyltriethoxy silane 등을 포함하는 복수의 실란계 커플링제가 개시되어 있으며, 그 중 Octyltriethoxy silane는 유리표면의 소수성을 강화하여 수분의 침투방지와 오염 방지를 위한 것이다. 따라서 본 발명과 같이 외부로 코팅층이 외부로 노출되지 않는 경우에는 Octyltriethoxy silane의 수분 침투방지와 오염 방지 기능은 불필요하고, 오히려 강화된 소수성 처리로 인해 접합성능을 저하시킬 수 있기 때문에 사용하지 않는 것이 바람직한데, 폴리비닐부틸랄(PVB)과의 접합력을 강화하기 위해 Octyltriethoxy silane 대신 바인더의 조성에 Alkylol ammonium salt 및 Acrylate copolymer를 추가하는 것이 바람직하다.Korean Patent No. 10-1261204 discloses a plurality of silane-based coupling agents including tetraethoxy silane, 3-glycidoxypropyltrimethodoxy silane, 3-methacryloxypropyltrimethodoxy silane, phenyltrimethoxy silane, and octyltriethoxy silane. Among them, The hydrophobic property of the surface is strengthened to prevent the penetration of water and the prevention of contamination. Therefore, in the case where the coating layer is not exposed to the outside as in the present invention, it is preferable not to use octyltriethoxy silane because it prevents the moisture penetration and the pollution prevention function of the octyltriethoxy silane and may lower the bonding performance due to the enhanced hydrophobic treatment. However, it is preferable to add Alkylol ammonium salt and acrylate copolymer to the composition of the binder instead of octyltriethoxy silane in order to strengthen the bonding strength with polyvinyl butyral (PVB).

또한, 바인더를 가수분해하여 실란계 커플링제의 분자량이 1,500~1,800 범위로 제한하는 것이 바람직하다. 왜냐하면, 상기 실란계 커플링제의 분자량이 1,500 미만인 경우에는 바인더의 점성이 작아 유리부재 표면에서 흐르기 때문에 균일한 두께로 분사하는 것이 어렵고, 1,800을 초과하는 경우에는 코팅층의 경도는 증가하나 소수성이 강화되어 폴리비닐부틸랄(PVB)과의 접합 성능이 저하되기 때문이다.It is also preferable to hydrolyze the binder to limit the molecular weight of the silane coupling agent to the range of 1,500 to 1,800. If the molecular weight of the silane-based coupling agent is less than 1,500, the viscosity of the binder is low and it flows on the surface of the glass member, so that it is difficult to spray uniformly. When the molecular weight exceeds 1,800, the hardness of the coating layer is increased but the hydrophobicity is strengthened This is because the bonding performance with polyvinyl butyral (PVB) decreases.

상기 용제는 코팅 조성물이 유리에 코팅될 때 적절한 흐름성과 건조 특성을 가져 대면적의 유리에 코팅하더라도 균일한 두께로 코팅될 수 있도록 PGMEA(Propylene Glycol Monomethyl Ether Acetate), 아세틸아세톤(Acetylaceton, 2-4-Pentandion), MEK(Methyl Ethyl Ketone), 이소프로폭시에탄올(Iso-Propoxyethanol), 에톡시에탄올(Ethoxyethanol) 및 메톡시에탄올(Methoxyethanol) 중 적어도 하나인 것이 바람직하다.The solvent has a proper flow property and drying property when the coating composition is coated on the glass, so that it can be coated with a uniform thickness even if it is coated on a large-area glass. The solvent is preferably selected from the group consisting of PGMEA (Acetlacetone) -Pentanion, Methyl Ethyl Ketone, Iso-Propoxyethanol, Ethoxyethanol, and Methoxyethanol.

상기 분산제는 질산을 포함하는 것을 예시할 수 있다.The dispersant may include nitric acid.

이와 같이 본 발명의 다기능성 접합유리는 각 유리부재에 형성된 한 쌍의 코팅층에서 서로 다른 기능을 수행하도록 구성할 수 있을 뿐만 아니라, 각 코팅층과 접합층의 접합 성능도 향상시킬 수 있는 장점이 있다.
As described above, the multifunctional laminated glass of the present invention can be configured to perform different functions in a pair of coating layers formed on each glass member, and the bonding performance between the respective coating layers and the bonding layer can be improved.

이하에서는 본 발명에 따른 다기능성 접합유리 제조방법의 바람직한 실시예를 상세히 설명한다. 다만, 앞서 설명한 구성요소와 동일 내지 유사한 구성요소에 대해서는 그 자세한 설명을 생략한다.Hereinafter, preferred embodiments of the method for producing a multi-functional bonded glass according to the present invention will be described in detail. However, the same or similar components as those described above will not be described in detail.

본 발명에 따른 다기능성 접합유리 제조방법은 크게 코팅 조성물을 마련하는 S1단계와, 제1유리부재의 일면에 상기 코팅 조성물을 이용하여 제1코팅층을 형성하고, 제2유리부재의 일면에 상기 코팅 조성물을 이용하여 제2코팅층을 형성하는 S2단계와, 상기 제1코팅층 상에 접합부재를 적층하고, 상기 접합시트 상에 상기 제2코팅층이 접하도록 상기 제2유리부재를 적층하는 S3단계와, 상기 제1유리부재 및 제2유리부재를 가열 및 가압하여 상기 접합부재를 상기 제1코팅층 및 제2코팅층과 열융착시키는 S4단계를 포함할 수 있다.A method for manufacturing a multi-functional bonded glass according to the present invention comprises the steps of: S1 providing a coating composition; forming a first coating layer on the first glass member by using the coating composition; A step S2 of forming a second coating layer by using a composition, a step S3 of laminating a joining member on the first coating layer and laminating the second glass member on the joining sheet so that the second coating layer is in contact with the joining member, And heating and pressing the first glass member and the second glass member to thermally fuse the bonding member with the first coating layer and the second coating layer.

상기 S1단계의 코팅 조성물은 적어도 1종의 분말과, 용제와, 분산제를 포함하는 코팅액을 마련하는 S1-1단계와, 실란계 커플링제, 메톡시프로판올, 물, 에탄올, 에폭시 수지, 질산, Alkylol ammonium salt 및 Acrylate copolymer를 이용하여 바인더를 제조하는 S1-2단계와, 상기 바인더를 가수분해하는 S1-3단계와, 상기 가수분해된 바인더에 에폭시 수지 및 상기 코팅액을 혼합하는 S1-4단계를 통해 제조되는 것이 바람직하다.The coating composition of the step (S1) is characterized by comprising a step S1-1 of providing a coating liquid containing at least one kind of powder, a solvent and a dispersing agent, and a step of adding a silane coupling agent, methoxypropanol, water, ethanol, a step S1-2 of producing a binder using ammonium salt and an acrylate copolymer, a step S1-3 of hydrolyzing the binder, and a step S1-4 of mixing the epoxy resin and the coating solution with the hydrolyzed binder It is preferable to be produced.

상기 S1-1단계의 상기 분말은 상술한 바와 같이, ATO(Antimony Tin Oxide), WO3, MoO3, AZO(Aluminium Zinc Oxide) 및 ITO(Indium Tin Oxide) 중 적어도 하나의 금속산화물 분말 또는 안료 분말인 것을 예시할 수 있다.As described above, the powder of the step S1-1 may be at least one of metal oxide powder or pigment powder of ATO (Antimony Tin Oxide), WO 3 , MoO 3 , AZO (Aluminum Zinc Oxide) and ITO (Indium Tin Oxide) Can be exemplified.

그리고 금속산화물 분말은 습식 분쇄 및 분산기를 이용하여 얻을 수 있고, 예를 들어 ATO, AZO 및 ITO의 각 입경이 50~60 nm가 되도록 분쇄 및 분산시킬 수 있는데, 입경을 50~60 nm로 한정하는 이유는 입경이 50 nm 미만에서는 가공의 어려움으로 인해 생산성이 저하될 수 있고, 60 nm를 초과하는 경우 빛이 투과될 때 미세하게 굴절이나 왜곡 현상이 발생될 수 있기 때문이다. 여기에서, 분쇄 및 분산 시간은 습식 분쇄 및 분산기와 그 평균 입경을 측정한 결과에 따라 적절히 조절할 수 있다.The metal oxide powder can be obtained by using a wet grinding and dispersing machine. For example, ATO, AZO and ITO can be pulverized and dispersed so as to have a particle diameter of 50 to 60 nm. The particle size of the metal oxide powder is limited to 50 to 60 nm If the particle diameter is less than 50 nm, productivity may be deteriorated due to difficulty in processing. If the particle diameter exceeds 60 nm, refraction or distortion may occur finely when light is transmitted. Here, the pulverizing and dispersing time can be appropriately adjusted according to the results of measurement of the average particle size of the wet pulverizing and dispersing machine.

한편, 금속산화물 분말 중 ATO, AZO, ITO 등의 금속산화물 코팅액을 제조할 경우 ATO, AZO 및 ITO 중 선택된 분말을 30~40 중량%로, 용제를 54.99~66.99 중량%로 분산제를 3.01-5.01 중량%로 혼합할 수 있으며, WO3, MoO3를 이용하여 금속산화물 코팅액을 제조할 경우 WO3 또는 MoO3 분말을 15~60 중량%로, 용제와 분산제를 40~85 중량%로 혼합할 수 있고, 이 경우 용제를 29.98~78.98 중량%로 분산제를 6.02~10.02 중량%로 혼합하는 것을 예시할 수 있다.Meanwhile, when metal oxide coating liquids such as ATO, AZO, and ITO in the metal oxide powder are prepared, the powder selected from ATO, AZO, and ITO is added to 30 to 40 wt%, the solvent to 54.99 to 66.99 wt%, the dispersant to 3.01 to 5.01 wt% When WO 3 or MoO 3 is used to prepare a metal oxide coating solution, WO 3 or MoO 3 powder may be mixed in an amount of 15 to 60 wt%, and a solvent and a dispersant may be mixed in an amount of 40 to 85 wt% , In which case the solvent may be mixed in an amount of 29.98 to 78.98% by weight and a dispersant in an amount of 6.02 to 10.02% by weight.

여기서, 상기 용제는 PGMEA 100중량부를 기준으로 아세틸아세톤은 15-20 중량부의 비율로, MEK는 30-35 중량부의 비율로, 이소프로폭시에탄올은 15-20 중량부의 비율로, 에톡시에탄올은 130-135 중량부의 비율로, 메톡시에탄올은 30-35중량부의 비율로 혼합될 수 있다. 그리고 상기 분산제는 질산 100 중량부를 기준으로 알킬암모늄염 600-1000 중량부의 비율로 혼합될 수 있다.Here, the solvent is used in an amount of 15-20 parts by weight of acetylacetone, 30-35 parts by weight of MEK, 15-20 parts by weight of isopropoxy ethanol, 130 parts by weight of ethoxyethanol, -135 parts by weight, methoxyethanol may be mixed in a proportion of 30-35 parts by weight. The dispersant may be mixed in a ratio of 600-1000 parts by weight of an alkylammonium salt based on 100 parts by weight of nitric acid.

상기 S1-2단계의 실란계 커플링제는 Tetraethoxy silane 100 중량부를 기준으로 3-Glycidoxypropyltrimethodxy silane 20~25중량부, 3-Methacryloxypropyltrimethodxy silane 3~5중량부, Phenyltrimethoxy silane 1~2중량부의 비율로 혼합될 수 있다.The silane coupling agent in the step S1-2 may be mixed with 20 to 25 parts by weight of 3-glycidoxypropyltrimethodoxy silane, 3 to 5 parts by weight of 3-methacryloxypropyltrimethodoxy silane and 1 to 2 parts by weight of phenyltrimethoxy silane based on 100 parts by weight of tetraethoxy silane have.

상기 S1-3단계는 상기 Tetraethoxy silane의 분자량이 1,500~1,800이 되도록 상기 바인더를 30~35℃의 온도 조건으로 20~30시간 동안 숙성시켜 가수분해하는 것이 바람직하다. 왜냐하면 상술한 바와 같이, 20~30시간을 초과 숙성하는 경우에는 Tetraethoxy silane의 분자량이 1,800을 초과하게 되어 소수성이 강화되어 접합 성능이 저하되기 때문이다.In the step S1-3, the binder is preferably hydrolyzed by aging the binder at a temperature of 30 to 35 DEG C for 20 to 30 hours so that the molecular weight of the tetraethoxy silane is 1,500 to 1,800. This is because, as described above, in case of aging for more than 20 to 30 hours, the molecular weight of tetraethoxy silane exceeds 1,800 and the hydrophobicity is strengthened, so that the bonding performance is lowered.

상기 S1-4단계는 상기 가수분해된 바인더에 에폭시 수지 및 상기 코팅액을 혼합하는 단계로서, 여기서 에폭시 수지는 분자량이 500~5,000 보다 바람직하게는 1,000~1,500이며, 바인더 100 중량부를 기준으로 1.0~10 보다 바람직하게는 5~6.5 중량부의 비율로 혼합할 수 있다.The step S1-4 is a step of mixing the hydrolyzed binder with an epoxy resin and the coating solution, wherein the epoxy resin has a molecular weight of 500 to 5,000, preferably 1,000 to 1,500, and 1.0 to 10 And more preferably 5 to 6.5 parts by weight.

상기 코팅액은 상기 바인더 및 에폭시 수지 혼합물과 1 : 0.8~1.2 중량비로 혼합될 수 있으며, 여기에 질산을 첨가 및 교반하여 PH가 3-4가 되도록 안정화시키면 코팅 조성물의 제조가 완료된다.The coating solution may be mixed with the binder and the epoxy resin mixture at a weight ratio of 1: 0.8-1.2, and nitric acid is added thereto and stirred to stabilize PH to 3-4, thereby completing the preparation of the coating composition.

상기 S2단계는 마이크로 그라비아 코팅법 등을 이용하여 상기 코팅 조성물을 제1유리부재 및 제2유리부재 표면에 코팅하여 제1코팅층 및 제2코팅층을 형성할 수 있다.In the step S2, the first coating layer and the second coating layer may be formed by coating the coating composition on the surfaces of the first glass member and the second glass member using a micro gravure coating method or the like.

상기 S3단계에서 제1유리부재, 접합부재(폴리비닐부틸랄 시트) 및 제2유리부재를 순차적으로 적층한 다음, S4단계를 통해 열융착하게 되면 다기능성 접합유리의 제조가 완료된다. 여기서 S3단계 및 S4단계는 이미 접합유리 제조 분야에서 공지된 사항이므로 그 자세한 설명은 생략한다.
If the first glass member, the joining member (polyvinyl butyral sheet), and the second glass member are sequentially laminated in step S3 and then heat-sealed in step S4, the production of the multi-functional bonded glass is completed. Here, steps S3 and S4 are already known in the field of manufacturing a bonded glass, so detailed description thereof will be omitted.
