강화유리의 컬러/무늬 코팅방법 {Method for Coating of Color/Design on Tempered Glass} Color / pattern coating method of tempered glass {Method for Coating of Color / Design on Tempered Glass}

본 발명은 유리에 컬러 또는 무늬를 형성시키는 방법에 관한 것으로서, 강화유리의 후면에 원하는 컬러 또는 무늬가 들어 있는 전사지를 코팅함으로써 외관이 미려한 강화코팅유리를 제조하는 방법에 관한 것이다.The present invention relates to a method of forming a color or pattern on the glass, and to a method of manufacturing a strengthened coated glass with a beautiful appearance by coating a transfer paper containing a desired color or pattern on the back of the tempered glass.

근래 기술의 향상 및 소득증가 등의 영향으로 가전제품, 가구 등에서 기술적인 면 보다는 디자인이 차지하는 비중 내지는 중요성이 점점 더 커지고 있다.Recently, due to the improvement of technology and the increase of income, the proportion or importance of design rather than technical aspect is increasing in home appliances and furniture.

근래 제품의 내부가 들여다보이는 소위 누드 디자인 계열의 가전제품들이 많이 선보이고 있는데, 이러한 경향의 한 예라고 할 수 있다.Recently, many household appliances of the so-called nude design line that show the inside of the product are introduced, which is an example of this trend.

그러나, 이와 같은 디자인의 발전도 최근에는 어느 정도 한계에 도달해 있어서 더 이상의 새로운 디자인들을 개발해내지 못하고 있는데, 이러한 시점에서 새로운 디자인 경향으로 대두할 가능성이 큰 것이 바로 유리라고 할 수 있다.However, the development of such a design has recently reached a certain limit, so that no new designs can be developed. At this point, it is the glass that is likely to emerge as a new design trend.

지금까지 유리는 주로 건축물의 내, 외장재로 주로 사용되어 왔으며, 실내에서는 책상, 장식장 등의 덮개로 사용됨으로써 가구의 부속자재로만 주로 사용되거나, 식탁 등 일부 제한된 품목에서만 주 자재로 사용되어 오던 것이 전부였다.Until now, glass has been mainly used as an interior and exterior material of buildings, and it is mainly used as an accessory for furniture by being used as a cover of a desk or a cabinet in an interior, or used as a main material only in some limited items such as a dining table. It was.

사실, 내염성, 내스크라치성, 내마모성 등 여러 가지 장점을 가지고 있고 청소가 용이하다는 장점이 있음에도 불구하고 유리가 냉장고, 세탁기, 김치냉장고, 전자렌지, 식기세척기 등 가전제품의 외부 마감장식재로서, 또한 장롱, 장식장, 싱크대 등 가구의 외부 마감장식재로서 사용되지 못하였던 것은, 사용시 또는 필요에 따른 이동시 깨질 염려가 있고 맑고 투명한 것 이외에 여러 가지 색상, 무늬 등 다양하고 미려한 외관을 갖출 수 없다는 것 때문이었다.In fact, despite its advantages such as flame resistance, scratch resistance and abrasion resistance, and easy cleaning, glass is also used as an external finishing material for household appliances such as refrigerators, washing machines, kimchi refrigerators, microwave ovens and dishwashers. It could not be used as exterior finishing material of furniture such as cabinets, sinks, sinks, etc., because it could be broken when using or moving as needed, and it could not have various and beautiful appearances such as various colors and patterns other than clear and transparent.

물론, 단순하게 유리의 후면에 스프레이 도장을 하는 방법이나 실크스크린 인쇄법 등이 유리에 적용되어 무늬나 컬러를 갖추고자 한 예가 없었던 것은 아니나, 스프레이 도장법의 경우 다양한 디자인을 구형하는 것이 불가능하고, 실크스크린 인쇄법의 경우 동일 디자인을 반복적으로 인쇄할 때 그 반복되는 동일한 디자인이 동일한 색상으로 인쇄되지 못하게 됨으로써, 동일한 컬러 무늬가 인쇄된 컬러 판유리를 대량으로 생산할 수 없다는 문제점을 가지고 있었다.Of course, the method of simply spray coating on the back of the glass or the silk screen printing method has not been applied to the glass to have a pattern or color, but in the case of the spray coating method, it is impossible to form various designs and silk In the case of the screen printing method, when the same design is repeatedly printed, the same design that is repeated cannot be printed in the same color, thereby having a problem in that a large quantity of color plate glass having the same color pattern is printed cannot be produced.

따라서, 컬러 또는 무늬가 다양하게 적용 가능함으로써 미려한 외관을 가질 수 있고, 반복적으로 제조할 시에도 재현성이 커서 대량생산이 가능할 뿐만 아니라, 사용시 또는 이동시에 깨질 염려도 없으며, 이에 따라 새로운 가전제품 및 가구 마감장식재로서 다양하게 적용할 수 있는 컬러 또는 무늬의 판유리가 제공되어야 할 시점이라고 할 수 있다.Therefore, it is possible to have a beautiful appearance by applying a variety of colors or patterns, it is possible to mass production because of the reproducibility is large, even when repeatedly manufactured, there is no fear of breaking during use or moving, accordingly new appliances and furniture As a decorative material, it can be said that it is time to provide colored or patterned sheet glass that can be variously applied.

본 발명은 이와 같은 종래기술의 문제점을 극복하고자 하는 것으로, 그 목적은, 컬러 또는 무늬가 다양하게 적용 가능함으로써 미려한 외관을 가질 수 있고, 반복적으로 제조할 시에도 재현성이 커서 대량생산이 가능할 뿐만 아니라, 사용시 또는 이동시에 깨질 염려도 없으며, 이에 따라 새로운 가전제품 및 가구 마감장식재로서 다양하게 적용할 수 있는, 컬러 또는 무늬를 가진 판유리 제조방법을 제공하고자 하는 것이다.The present invention is to overcome the problems of the prior art, the object of the present invention is that the color or pattern can be applied in a variety of ways to have a beautiful appearance, it is possible to mass-produce large repeatability even when repeatedly produced There is no fear of breakage during use or movement, and accordingly to provide a method for manufacturing a plate glass having a color or pattern, which can be variously applied as a new home appliance and furniture finishing material.

이를 위한 본 발명은, 코팅할 강화유리를 깨끗하게 세척하는 세척단계와, 에어스프레이를 이용하여 세척된 강화유리의 일면에 10-20㎛의 두께로 균일하게 접착제를 분무, 도장하는 하부도장단계와, 70-90℃의 온도에서 5-15분 동안 건조시키는 1차건조단계와, 110-130℃의 온도로 유지되는 가열롤러를 이용하여 하부도장의 상면에 전사지를 가압, 전사함으로써 컬러 또는 무늬를 전사하는 전사단계와, 에어스프레이를 이용하여 전사면의 상면에 25-35㎛의 두께로 균일하게 페인트와 UV경화성 도료중 어느 하나를 분무, 도장하는 상부도장단계와, 페인트 도장의 경우 70-90℃의 온도에서 5-15분 동안 건조시키고 UV경화성 도료 도장의 경우 2-3초 동안 자외선을 조사함으로써 건조시키는 2차건조단계가 순차적으로 이루어지는 것으로 구성되는, 강화유리의 컬러/무늬 코팅방법을 제공하는 것으로 구현된다. To this end, the present invention, the washing step to clean the tempered glass to be coated, the lower coating step of uniformly spraying, coating the adhesive to a thickness of 10-20㎛ on one surface of the tempered glass cleaned using an air spray, Transfer the color or pattern by pressing and transferring the transfer paper to the upper surface of the lower coating by using the first drying step of drying for 5-15 minutes at a temperature of 70-90 ℃ and a heating roller maintained at a temperature of 110-130 ℃ A transfer step of spraying, an upper spraying step of spraying and painting one of paint and UV curable paint uniformly to a thickness of 25-35 μm on the upper surface of the transfer surface by using an air spray, and 70-90 ° C. in the case of paint coating Color / pattern of tempered glass, consisting of a second drying step sequentially consisting of drying for 5-15 minutes at a temperature of 5 seconds and drying by irradiating ultraviolet light for 2-3 seconds in the case of UV-curable paint coating It is implemented to provide a coating method.

본 발명은 유리에 컬러 또는 무늬를 형성시키는 방법에 관한 것으로서, 강화유리의 후면에 원하는 무늬가 들어 있는 전사지를 코팅함으로써 외관이 미려한 강화코팅유리를 제조하는 방법에 관한 것이다.The present invention relates to a method of forming a color or pattern on the glass, and to a method of manufacturing a tempered coated glass with a beautiful appearance by coating a transfer paper containing a desired pattern on the back of the tempered glass.

본 발명에서는 코팅되는 유리로서 강화유리(Tempered Glass)를 사용하였고, 컬러 또는 무늬를 가지는 전사지로는 인쇄층을 UV 경화성 도료로 보호하는 보호층이 형성된 것을 사용되었으며, 전사지를 강화유리에 접착하기 위한 접착제로는 속건형 아크릴 우레탄 재질에 외관의 미려함까지 고려하여 펄을 혼합한 것이 사용되었고, 전사지 접착후 후면처리를 위한 마감코팅재로는 초속건형 아크릴 우레탄 재질의 것을 사용하였다.In the present invention, tempered glass was used as the glass to be coated, and a transfer layer having a color or pattern was used as a protective layer for protecting the printing layer with a UV curable paint. As an adhesive, a mixture of pearls was used in consideration of the beauty of appearance in a quick-drying acrylic urethane material, and a fast-drying acrylic urethane material was used as a finish coating material for the back treatment after the transfer paper was bonded.

유리는 기본적으로 내염성, 내스크라치성, 내마모성 등에서 장점을 가지고 있고 쉽게 오염되지 않을 뿐만 아니라 청소가 용이하다는 또 다른 장점을 가지고 있으나, 충격에 의해 깨질 염려가 있기 때문에 가전제품 또는 가구의 외부 마감재로서 사용하기가 쉽지 않은 물질이다.Glass has the advantages of flame resistance, scratch resistance, and abrasion resistance, and has another advantage of not only being easily contaminated but also easy to clean.However, glass can be broken by impact, so it is used as an external finishing material for home appliances or furniture. It is not easy to do.

이러한 면에서 볼 때, 본 발명에 강화유리를 사용한 것은 가전제품 및 가구의 외부 마감장식재로 사용된다는 특성을 반영한 것으로 쉽게 깨지거나 긁히지 않는 내구성을 가져야 하기 때문이다.In view of this aspect, the use of tempered glass in the present invention reflects the property of being used as an external finishing material for home appliances and furniture, because it must have durability that is not easily broken or scratched.

본 발명에서 컬러 또는 무늬를 가지는 전사지로는 시중에서 소위 UV바니쉬?라는 이름으로 불리우는 UV 경화성 도료가 코팅된 것이 사용되었는데, 이는 UV 경화성 도료가 내마모성, 내스크라치성, 내약품성 등이 우수하여 보호층으로서 장점을 가지고 있기 때문이다.In the present invention, the transfer paper having a color or a pattern is called UV varnish ? The coating with UV curable paint called "name" was used, because UV curable paint has an excellent wear resistance, scratch resistance, chemical resistance and the like as a protective layer.

이와 같은 전사지는, 도 1에 나타낸 바와 같이, 전사후 박리될 박리지로 사용되는 폴리에스터 필름(11) 일면에 보호층(12)으로서 UV바니쉬?를 도포하고 그 위에 원하는 컬러 또는 무늬를 인쇄하여 인쇄층(13)을 형성시킨 것으로서, 강화유리에 전사된 후 박리지는 박리되고 인쇄층과 UV바니쉬 보호층만이 남는 구성이다.As shown in Fig. 1, such a transfer paper is a UV varnish ? As a protective layer 12 on one surface of the polyester film 11 used as a release paper to be peeled off after transfer . The coated layer 13 was formed by applying and printing a desired color or pattern thereon, and after the transfer to the tempered glass, the release paper was peeled off and only the printed layer and the UV varnish protective layer remained.

전사지를 강화유리에 접착하기 위한 접착제로는 투명한 속건형 아크릴 우레탄 재질에 펄을 혼합한 것이 사용되었는데, 아크릴 우레탄이 사용된 것은 유리에 사용된다는 특성상 후면 인쇄층의 컬러 또는 무늬가 보일 수 있도록 투명해야 하기 때문이며, 여기에 외관의 미려함까지 고려하여 펄이 혼합된 것을 사용하였다.The adhesive for bonding the transfer paper to the tempered glass was a mixture of pearl and a transparent quick-drying acrylic urethane material. Acrylic urethane should be transparent so that the color or pattern of the back printing layer can be seen due to the nature of the glass. This is because, in consideration of the beauty of the appearance here, a mixture of pearl was used.

본 발명에서 실제 사용된 접착제는 이미 제품화되어 상용되고 있는 것으로서 크리스탄 투명(GL)?이라는 이름으로 판매되고 있는 것에 펄을 혼합한 것이다.The adhesive actually used in the present invention has already been commercialized and used as a Christian transparent (GL) ? The pearl is mixed with what is sold under the name.

한편, 본 발명에서 전사지 전사후 도료를 이용 후면처리함으로써 전사된 컬러 또는 무늬의 보호층을 형성하기 위한 마감코팅재로는 불투명한 일반 페인트 또는 불투명한 초속건형 아크릴 우레탄 재질의 유색 도료를 사용할 수 있는데, 아크릴 우레탄의 경우 전사지의 보호층과 마찬가지로 UV 경화성 물질로서, 내열성, 내약품성, 내마모성, 내식성 등이 커서 인쇄층의 손상을 방지하는 효과가 극대화된 제품이며, 불투명한 재질을 사용한 것은 후면에 사용된다는 특성상 광이 투과되어 인쇄층 컬러 또는 무늬의 미려함에 영향을 주는 것을 방지하기 위해서이다.On the other hand, in the present invention, as a finish coating material for forming a protective layer of the color or pattern transferred by the post-treatment of the transfer paper after the transfer paint can be used opaque general paint or opaque ultra-fast drying acrylic urethane colored paint, Acrylic urethane, like the protective layer of transfer paper, is a UV-curable material, which has a high heat resistance, chemical resistance, abrasion resistance, and corrosion resistance, and thus maximizes the effect of preventing damage to the printed layer, and an opaque material is used on the back side. This is to prevent light from being transmitted and affecting the beauty of the printed layer color or pattern due to its characteristics.

이하, 도면을 참고로 하여 본 발명을 더 구체적으로 설명하고자 하나, 본 발명을 이에 제한하고자 하는 것은 아니다.Hereinafter, the present invention will be described in more detail with reference to the drawings, but the present invention is not intended to be limited thereto.
