Description
본 발명은 유리섬유 강화 플라스틱 표면처리방법에 관한 발명으로, 더욱 상세하게는 유리섬유 강화 플라스틱 소재로 제조되는 제품에 대하여 이중패턴필름을 이용한 표면처리가 이루어지도록 구성함으로써 종래의 표면처리방식에 비해 공정을 간소화하고 제품의 심미감 및 고품질화를 가능하게 하는 기술에 관한 것이다.The present invention relates to a method for treating the surface of glass fiber reinforced plastic. More specifically, the present invention relates to a surface treatment method for glass fiber reinforced plastic, and more specifically, by configuring the surface treatment using a double pattern film for products made of glass fiber reinforced plastic material, the process is compared to the conventional surface treatment method. It is about technology that simplifies and enables the aesthetics and high quality of products.
일반적으로, 각종 제품의 외관을 구성하는 케이스 또는 커버는 제품의 심미성을 표출하고 타제품과의 차별성을 부여하는 요소로서 소비자의 선호도에 따른 최신 디자인 트렌드를 반영할 수 있으므로 케이스 또는 커버에 대한 표면처리 기술 역시 그 중요성이 커지고 있다.In general, cases or covers that make up the exterior of various products are elements that express the aesthetics of the product and differentiate it from other products, and can reflect the latest design trends according to consumer preferences, so surface treatment technology for cases or covers Its importance is also growing.
스마트폰, 태플릿PC, TV, 냉장고 등의 전자제품 케이스나 자동차의 대쉬보드 등의 제품은 대부분 플라스틱 사출물로 제조되는바, 이러한 플라스틱 제품의 표면처리방법에는 도장, 도금, 진공증착, 필름전사 등의 다양한 종류가 있다.Most products such as electronic product cases such as smartphones, tablet PCs, TVs, refrigerators, and automobile dashboards are manufactured with plastic injection molding. Surface treatment methods for these plastic products include painting, plating, vacuum deposition, and film transfer. There are various types of .
도장은 도료용제를 제품 표면에 스프레이 도장하여 제품 표면에 도막을 형성하는 처리 방식으로 색상 선택이 자유롭고 작업성이 간편한 이점이 있으나 내마모성이 취약하고 질감 형성을 위한 추가적인 처리가 요구되는 단점이 있다.Painting is a treatment method that forms a coating film on the surface of a product by spraying a paint solvent onto the product surface. It has the advantage of freedom in color selection and easy workability, but has the disadvantage of poor abrasion resistance and requiring additional processing to form texture.
도금은 제품 표면에 금속 피막을 형성하여 금속 광택 또는 질감을 형성하는 표면 처리 방식으로 내마모성 및 내식성을 향상하나 비도전성인 플라스틱 제품에 적용하기 번거롭고 작업 과정에서 각종 유해물질이 발생하는 단점이 있다.Plating is a surface treatment method that forms a metal film on the surface of a product to create a metallic luster or texture. It improves wear resistance and corrosion resistance, but has the disadvantage of being cumbersome to apply to non-conductive plastic products and generating various harmful substances during the work process.
진공증착은 전기도금의 단점을 개선하여 물리적으로 피막을 증착하는 표면 처리 방식으로 플라스틱 제품에 금속 피막을 형성 시 진공증착에 의한 표면 처리방식이 적용된다.Vacuum deposition is a surface treatment method that physically deposits a film by improving the shortcomings of electroplating. When forming a metal film on a plastic product, the surface treatment method by vacuum deposition is applied.
또한, 최근에는 플라스틱 제품을 성형하는 과정에서 금형에 필름을 공급한 상태로 수지를 사출하여 일체로 결합되도록 하는 인서트 인몰드 방식의 표면처리방법이 이용되고 있다.Additionally, recently, in the process of molding plastic products, an insert in-mold surface treatment method has been used in which resin is injected while supplying a film to a mold to be integrated into one piece.
공지된 종래 기술의 일례로서, 한국공개특허 제 10 - 2018 - 0082179 호에는 PET로 이루어지는 투명한 베이스 필름과, 베이스 필름의 일면에 적층되며 색상을 포함하는 컬러 UV도료층과, 컬러 UV도료층의 일면에 증착된 증착층을 포함하는 금속질감 필름을 구성한다.As an example of known prior art, Korean Patent Publication No. 10 - 2018 - 0082179 includes a transparent base film made of PET, a color UV paint layer laminated on one side of the base film and containing color, and one side of the color UV paint layer.

A home appliance consisting of a printing layer on which a design is printed, an adhesive layer applied on the printing layer and containing metal flakes, and a background layer made of opaque synthetic resin that adheres to the adhesive layer and promotes the color of the printing layer. Constructs a film for attaching transparent panels.
한편, 통상적인 합성수지에 유리섬유를 결합하여 형성하는 유리섬유 강화 플라스틱(GLASS FIBER REINFORCED PLASTIC, GFRP)은 경량성, 고강도 특성에 의해 최근 적용 분야를 확대하고 있다.Meanwhile, glass fiber reinforced plastic (GLASS FIBER REINFORCED PLASTIC, GFRP), which is formed by combining glass fiber with a typical synthetic resin, has recently been expanding its application areas due to its lightweight and high strength characteristics.
이와 같은 유리섬유 강화 플라스틱 제품에 대한 표면처리는 주로 도장이나 도금에 의해 이루어지고 있는바, 예컨대 한국등록특허 제 10 - 1993805 호에는 삼차원 곡면 또는 평면형상이고, 유리섬유 강화 플라스틱을 포함한 섬유강화 복합소재로 형성되고, 외면에 프라이머 도포층, 반투명 코팅층, 그라데이션 코팅층 및 클리어 코팅층이 순차적으로 적재된 그라데이션 도장층을 포함하는 휴대단말 케이스를 구성한다.The surface treatment of such glass fiber reinforced plastic products is mainly done by painting or plating. For example, in Korean Patent No. 10 - 1993805, it has a three-dimensional curved or flat shape and is made of a fiber reinforced composite material including glass fiber reinforced plastic. It is formed and constitutes a mobile terminal case including a gradient coating layer in which a primer coating layer, a translucent coating layer, a gradient coating layer, and a clear coating layer are sequentially stacked on the outer surface.
다른 예로서, 한국등록특허 제 10 - 2451792 호에는 합성수지와 유리섬유를 혼합하여 강화 합성수지 사출물을 형성하고, 사출물의 표면을 망간에칭, 중화, 글래스에칭, 클리닝, 컨디셔닝, 활성화, 엑셀러레이터, 1차도금, 동도금, 프리딥, 파라듐촉매, 2차도금, 후처리하는 단계를 거쳐 처리하는 일련의 에칭 및 도금방법을 구성한다.As another example, in Korean Patent No. 10 - 2451792, synthetic resin and glass fiber are mixed to form a reinforced synthetic resin injection molded product, and the surface of the injection molded product is subjected to manganese etching, neutralization, glass etching, cleaning, conditioning, activation, accelerator, and primary plating. It consists of a series of etching and plating methods that go through the steps of copper plating, pre-dip, palladium catalyst, secondary plating, and post-processing.
상술한 바와 같이 각종 전자제품의 외관을 구성하는 케이스나 커버 등의 플라스틱 제품에 대한 표면처리방법은 도장, 도금, 진공증착, 필름전사 등의 다양한 종류가 있으며, 최근에는 필름을 이용한 인서트 인몰드 방식의 표면처리방법이 주로 이용되고 있다.As mentioned above, there are various types of surface treatment methods for plastic products such as cases and covers that make up the exterior of various electronic products, such as painting, plating, vacuum deposition, and film transfer. Recently, the insert in-mold method using film has been used. Surface treatment methods are mainly used.
종래 기술에 따른 인몰드 방식의 표면처리에 적용되는 필름은 PET로 이루어지는 기재층과, 기재층의 일면에 적층되는 인쇄층과, 인쇄층의 일면에 증착층과, 사출물의 외면에 부착하는 접착제층을 형성하도록 구성한다.The film applied to the surface treatment of the in-mold method according to the prior art consists of a base layer made of PET, a printed layer laminated on one side of the base layer, a deposition layer on one side of the printed layer, and an adhesive layer attached to the outer surface of the injection product. It is configured to form.
그러나, 이와 같은 종래의 플라스틱 기재층을 베이스로 구비하는 필름은 경질의 플라스틱 기재의 사용으로 인해 필름 전체의 두께를 증대하여 피착물의 곡면 부위에 부착성을 현저히 저하하고 컬링 및 박리 현상을 초래하는 문제점이 있다.However, the film having such a conventional plastic base layer as a base increases the overall thickness of the film due to the use of a hard plastic base layer, significantly reduces adhesion to the curved area of the adherend, and causes curling and peeling phenomena. There is.
아울러, 종래의 플라스틱 기재층을 베이스로 구비하는 필름은 최근 스마트폰의 후면 커버와 같이 테두리 형상이 없는 얇은 평판 플라스틱 사출 제품에 부착 시 플라스틱 기재의 두께 및 장력으로 인해 제품이 휘어지는 현상이 발생하게 되어 제품 품질 및 완성도를 현저히 저하하는 문제점이 있다.In addition, when a film based on a conventional plastic base layer is attached to a thin flat plastic injection product without a border shape, such as the back cover of a smartphone, the product bends due to the thickness and tension of the plastic base layer. There is a problem that significantly reduces product quality and completeness.
특히, 유리섬유 강화 플라스틱(GFRP) 제품의 표면처리에 종래의 플라스틱 기재층을 베이스로 구비하는 필름을 적용할 경우 사출 과정에서 유리섬유가 노출되는 문제를 야기하고 결국 추가적인 표면 샌딩 공정을 불가피하게 실시해야 하므로 생산성 저하 문제로 인해 대부분 도장이나 도금에 의한 표면처리가 이루어지고 있다.In particular, when a film based on a conventional plastic base layer is applied to the surface treatment of a glass fiber reinforced plastic (GFRP) product, it causes the problem of glass fibers being exposed during the injection process and ultimately requires an additional surface sanding process. Due to the problem of low productivity, most surface treatments are done through painting or plating.
그러나, 유리섬유 강화 플라스틱 제품의 도장 또는 도금 처리방법 역시 상기 종래 기술에서와 같은 일련의 복잡한 공정을 수반하는바, 결국 GFRP가 가진 경량성, 고강도 등의 이점에도 불구하고 그 활용 범위가 매우 제한적인 실정에 있다.However, the painting or plating method of glass fiber reinforced plastic products also involves a series of complex processes as in the prior art, and ultimately, despite the advantages of GFRP such as lightness and high strength, its application range is very limited. It is in reality.
이에 본 발명에서는 상술한 바와 같은 종래 기술의 문제점을 해결하기 위하여 발명한 것으로서,Accordingly, the present invention was invented to solve the problems of the prior art as described above.

따라서, 본 발명은 종래의 인몰드 사출에 의한 표면처리에 사용되는 플라스틱 기재층을 베이스로 구비하는 필름에 비해 필름 전체의 두께를 현저히 감소하여 피착물의 코너부 또는 곡면 부위에 부착성을 현저히 증대하고 컬링 및 박리 현상을 방지하여 불량률을 저감할 수 있는 이점이 있다.Therefore, the present invention significantly reduces the overall thickness of the film compared to a film based on a plastic base layer used for surface treatment by conventional in-mold injection, significantly increases adhesion to corners or curved surfaces of the adherend, and It has the advantage of reducing the defect rate by preventing curling and peeling.
특히, 기존에 플라스틱 기재층을 베이스로 구비하는 필름 사용시 복잡한 공정 및 낮은 수율로 인해 대부분 도장이나 도금에 의한 표면처리가 적용되었던 유리섬유 강화 플라스틱 제품에 대하여 무기재 이중패턴필름을 인서트 인몰드 또는 접합 방식으로 간편하게 적용할 수 있으므로 종래의 표면처리방식에 비해 공정을 대폭 간소화하고 생산성을 향상할 수 있는 효과가 있다.In particular, for glass fiber reinforced plastic products that were mostly surface treated by painting or plating due to the complex process and low yield when using a film with a plastic base layer as a base, an inorganic double pattern film can be inserted, in-molded or bonded. Because it can be easily applied, it has the effect of greatly simplifying the process and improving productivity compared to conventional surface treatment methods.
아울러, 본 발명은 이중 필름층에 의해 필요에 따라 단일 패턴 또는 이중패턴의 구현이 용이하여 다양한 심미감 및 입체감을 제공하므로 제품의 고품질화가 가능함에 따라 GFRP 제품을 보다 다양한 분야에 활용 가능하도록 하는 효과를 기대할 수 있다.In addition, the present invention provides a variety of aesthetics and three-dimensional effect by making it easy to implement a single pattern or a double pattern as needed by the double film layer, thereby enabling high quality of the product, which has the effect of allowing GFRP products to be used in a wider range of fields. can be expected.

특히, 종래에 도장이나 도금에 의한 복잡한 공정을 거쳐 표면처리가 이루어졌던 유리섬유 강화 플라스틱 제품에 대하여 무기재 이중패턴필름을 인서트 인몰드 또는 접합 방식으로 간편하게 적용할 수 있으므로 공정을 대폭 간소화하고 생산성을 향상할 수 있는 효과가 있다.In particular, the inorganic double pattern film can be easily applied by insert in-mold or bonding method to glass fiber reinforced plastic products that had previously been surface treated through complex processes such as painting or plating, greatly simplifying the process and increasing productivity. There is an effect that can be improved.
또한, 본 발명은 이중 필름층에 의해 필요에 따라 단일 패턴 또는 이중 패턴의 구현이 용이하여 다양한 심미감 및 입체감을 제공하므로 제품의 고품질화가 가능함에 따라 GFRP 제품을 보다 다양한 분야에 활용 가능하도록 하는 등의 효과가 있으므로 산업상 이용 가능성이 매우 클 것으로 기대된다.In addition, the present invention provides a variety of aesthetics and a three-dimensional effect by making it easy to implement a single or double pattern as needed by using a double film layer, so it is possible to improve the quality of the product, allowing GFRP products to be used in a wider range of fields, etc. Because of its effectiveness, it is expected to have great potential for industrial use.
