적외선 반사 적층체{Infrared Ray Reflection Laminate}Infrared Ray Reflection Laminate

본 발명은 공압출 폴리카보네이트 적외선 반사 적층체 및 그 제조방법에 관한 것으로, 보다 구체적으로는 폴리카보네이트 수지와 적외선반사필름 조성물을 공압출공정에 의해 접착시킴으로써 적외선을 차단하는 효과를 갖는 적외선 반사 적층체 및 그 제조방법에 관한 것이다.The present invention relates to a coextruded polycarbonate infrared reflective laminate and a method of manufacturing the same, and more particularly, to an infrared reflective laminate having an effect of blocking infrared rays by adhering a polycarbonate resin and an infrared reflective film composition by a coextrusion process. And to a method for producing the same.

폴리카보네이트 수지는 투명도가 우수하고, 강도가 우수한 특성이 있는 수지로 유리 대용으로 사용되고 있으나, 적외선을 투과시켜 내부 온도를 상승시키게 되는 단점이 있었다. 특히, 천창(SKYLIGHT), 캐노피(CANOPY), 건축물의 연결통로(Walkway), 건물 및 거실, 공장 등의 채광판 및 지붕재, 고층 아파트의 창호 및 안전유리, 박물관, 병원의 창, 수영장, 실내체육관 지붕, 사격장, 수족관 및 식물원, 온실, 동물원의 울타리, 공중전화 박스 등에 주로 사용되었으나, 여름철에는 복사열에 의해 내부 온도가 상승하게 되는 단점이 있었다.Polycarbonate resin is a resin having excellent transparency and excellent strength and is used as a glass substitute, but has a disadvantage of increasing the internal temperature by transmitting infrared rays. In particular, skylights, canopies, walkways for buildings, skylights and roofing materials for buildings and living rooms, factories, windows and safety glass in high-rise apartments, museums, hospital windows, swimming pools, indoor gymnasiums Roofs, shooting ranges, aquariums and botanical gardens, greenhouses, fences of zoos, public telephone boxes, etc. were mainly used, but in summer, the internal temperature was increased by radiant heat.

이러한 단점을 해결하기 위하여 종래에는 적외선 반사입자를 폴리카보네이트와 혼련하여 시트를 제조하여 복사열을 차단하는 방법을 사용하였다. 그러나 폴리카보네이트와 적외선반사입자를 혼련하는 경우에는 상기 용도에 사용하는 5T, 10T 또는 15T 등의 두께의 투명수지를 제조하는 경우에 투명도가 감소되어 외부의 사물을 명확하게 볼 수 없는 단점이 있었다.In order to solve this disadvantage, conventionally, the infrared reflective particles were kneaded with polycarbonate to prepare a sheet to block radiant heat. However, when kneading polycarbonate and infrared reflecting particles, transparency is reduced when a transparent resin having a thickness of 5T, 10T, or 15T is used for the above application, so that external objects cannot be clearly seen.

본 발명은 상기한 문제점을 해결하기 위하여 안출된 것으로, 폴리카보네이트 수지와 적외선반사필름 조성물을 공압출하여 적외선반사필름층을 형성하여 필름이 시트상에 영구적으로 고착되게하고, 또한 적외선 반사 필름층을 ㎛단위로 적층함으로써 투명도를 유지하므로 제조 공정을 단순화 시키고, 제조 원가를 절감하는 적외선 반사 적층체의 제조방법을 제공하고자 한다.The present invention has been made to solve the above problems, coextruded polycarbonate resin and infrared reflecting film composition to form an infrared reflecting film layer so that the film is permanently fixed on the sheet, and also the infrared reflecting film layer Since the lamination is carried out by the μm unit to maintain transparency, to simplify the manufacturing process, to provide a manufacturing method of the infrared reflective laminate to reduce the manufacturing cost.

또한 본 발명의 다른 목적은 상기 방법으로 제조된 공압출 폴리카보네이트 적외선반사 적층체를 제공하고자 한다.Another object of the present invention is to provide a co-extruded polycarbonate infrared reflecting laminate prepared by the above method.

상기 목적을 달성하기 위한 본 발명의 공압출 폴리카보네이트 적외선반사 적층체의 제조방법은 펠렛 또는 분말의 폴리카보네이트 수지, 적외선반사 필름을 제조하기 위한 수지조성물을 각각의 압출기에 넣고 용융 압출시킨 다음, 하나의 압출 다이를 통하여 공압출시키는 것을 특징으로 한다.Method for producing a co-extruded polycarbonate infrared reflecting laminate of the present invention for achieving the above object is a pellet or powder polycarbonate resin, a resin composition for producing an infrared reflecting film into each extruder and melt extrusion, then It is characterized by co-extrusion through the extrusion die of.

본 발명의 공압출 폴리카보네이트 적외선반사 적층체는 1) 폴리카보네이트 수지층; 2) 상기 폴리카보네이트 수지층의 상부에 적층되며, 투명수지와 적외선반사입자로 구성되는 적외선반사필름층; 으로 이루어진다.The coextruded polycarbonate infrared reflecting laminate of the present invention comprises: 1) a polycarbonate resin layer; 2) an infrared reflecting film layer laminated on the polycarbonate resin layer and composed of a transparent resin and infrared reflecting particles; Is done.

이와 같이 폴리카보네이트 수지를 이용한 적층체 필름 또는 쉬트를 한번의 공정에 의한 공압출 적층체로 제조하기 위해 가장 중요한 점은 폴리카보네이트 수지가 적외선반사필름과 잘 접착이 되어야 하며, 박리현상이 발생하지 않아야 한다. 또한, 공압출 적층체로 적용하기 위해서는 두개 이상의 압출기를 통해서 폴리카보네이트 수지, 적외선반사 필름을 제조하기 위한 수지조성물 등을 각각의 압출기에서 용융시킨 후 캐스팅이나 관 형태의 하나의 다이를 통해서 순간적으로 접착시켜야 한다.As such, the most important point for producing a laminate film or sheet using a polycarbonate resin into a coextruded laminate by one process is that the polycarbonate resin should be well adhered to the infrared reflecting film and there should be no peeling phenomenon. . In addition, in order to apply as a co-extruded laminate, polycarbonate resin, resin composition for manufacturing infrared reflecting film, etc. through two or more extruders must be melted in each extruder, and then instantaneously bonded through a die of casting or tube form do.

본 발명은 적외선반사 필름 수지조성물로 적층될 수 있는 적절한 수지 조성물을 선택한 다음, 폴리카보네이트 수지, 적외선반사 필름 수지조성물을 동시에 용융 압출하여 하나의 캐스팅 다이를 통해 적층체를 제조함으로써 본 발명의 공압출 폴리카보네이트 적외선반사 적층체의 제조방법을 완성하였다.The present invention selects a suitable resin composition that can be laminated with an infrared reflecting film resin composition, and then simultaneously melt-extrudes a polycarbonate resin and an infrared reflecting film resin composition to produce a laminate through one casting die to co-extrude the present invention. The manufacturing method of the polycarbonate infrared reflecting laminated body was completed.

It is prepared using 0.1 to 3 parts by weight of infrared reflecting particles based on 100 parts by weight of the transparent resin.

상기 투명수지로는 폴리카보네이트를 포함하여 에폭시계, 멜라민계, 페놀계, 아크릴계, 우레탄계 및 폴리에스테르계에서 선택되는 어느 하나이상을 사용할 수 있으나 기재인 폴리카보네이트와 동이한 투명수지인 폴리카보네이트가 가장 좋다.As the transparent resin, any one or more selected from epoxy, melamine, phenol, acryl, urethane, and polyester may be used, including polycarbonate, but polycarbonate, which is the same transparent resin as the base polycarbonate, is most good.

상기 적외선반사입자로는 티타늄산화물, 티탄산칼륨(Potassium Titanate), 프탈로시아닌(Phthalocyanine)계, 시아닌(Cyanine)계, 나프탈로시아닌(Naphthalocyanine)계, 퀴논(Quinone)계, 상기 티탄산 칼륨과 상기 프탈로시아닌계와 상기 시아닌계와 상기 나프탈로시아닌계 및 상기 퀴논계의 변형된 금속배위결합화합물, 니켈 디티올계(Nickel Dithiol) 및 암모늄염(Ammonium Salt)중에서 선택되는 어느 하나이상의 적외선 반사입자를 사용한다. The infrared reflecting particles include titanium oxide, potassium titanate, phthalocyanine, cyanine, naphthalocyanine, quinone, quenched titanate and the phthalocyanine.

If the particles are too small, the particles are aggregated to make the dispersion nonuniform. If the particles are large, the surface of the molded article is not smooth, and there is a problem of being opaque.
