The composite nonwoven fabric is used for manufacturing an adiabatic product such as a refrigerator door, Since the composite nonwoven fabric is firmly fixed to the case by providing the composite nonwoven fabric so that the nonwoven fabric comes into contact with the inner surface of the case and the foamed material is injected into the case to manufacture the heat insulating product, It is possible to prevent the case from being deformed even when the volume and the pressure increase due to the injection of the foam, This will be through the thermal insulation can provide excellent thermal insulation products.

본 발명에 따른 복합부직포의 제조 방법을 도1의 순서도를 참고하여 설명하면, 먼저, 종이 공급 단계(S1)는 종이(110)를 공급하는 단계로, 종이(110)는 내구성이 강한 종이(110)를 사용하며, 그 예로는 크라프트지가 있으며, 도2에 도시한 바와 같이, 공급하는 종이(110)는 자유회전하는 공급롤러(300)에 거치되어 풀리면서 공급되도록 한다.1, the paper feeding step S1 is a step of supplying paper 110. The paper 110 is a paper sheet 110 having a high durability As shown in FIG. 2, the paper 110 to be fed is placed on a freely rotating feed roller 300 and fed in a loose state.

참고로, 종이(110)로 적용하는 크라프트지(kraft paper)는 화학펄프의 일종인 미표백 크라프트펄프(kraft pulp, 황산염펄프, sulfate pulp)를 주원료로 제조된 종이(110)로, 강도가 우수하여 주로 포장용지로 이용된다.For reference, the kraft paper to be applied to the paper 110 is paper 110 made of kraft pulp (sulfate pulp), which is a kind of chemical pulp, And is mainly used as wrapping paper.

그리고 수지 도포 단계(S2)는 공급된 종이(110)에 용융된 수지(130)를 도포하는 단계로, 도포하는 수지(130)는 저밀도폴리에틸렌(LDPE, Low Density Polyethylene)을 적용하는데, 도2에 도시한 바와 같이, 수지(130)는 티다이(400)(T다이)의 내부에서 용융 온도로 스크류로 혼합하면서 배출(압출)하면서 종이(110)에 도포하는데, 티다이(400)에서 압출되는 수지(130)는 종이(110)의 폭에 맞게 균일한 두께로 용융된 수지(130)를 종이(110)에 도포한다.The resin applying step S2 is a step of applying the molten resin 130 to the supplied paper 110. The resin 130 to be applied is low density polyethylene (LDPE) As shown in the drawing, the resin 130 is applied to the paper 110 while being discharged (extruded) while being mixed with a screw at a melting temperature inside the T die 400 (T die) The resin 130 applies the melted resin 130 to the paper 110 at a uniform thickness corresponding to the width of the paper 110. [

한편, 티다이(400)는 균일한 양의 수지(130)를 압출하지만, 필요에 따라, 종이(110)에 도포된 수지(130)는 나이프(미도시)에 의해서 도포된 수지(130)의 두께를 더 얇게 균일한 두께로 펴면서 도포하는데, 도포하는 수지의 두께는 30∼40㎛ 정도로 도포한다.The resin 130 applied to the paper 110 is pressed against the resin 130 coated with a knife (not shown) The thickness of the resin to be coated is 30 to 40 占 퐉 or so.

그리고 냉각 단계(S3)는 종이(110)에 도포된 수지(130)를 180℃ 이하로 냉각하는 단계로, 티다이(400)로 압출되는 수지(130)는 고온으로 용융된 상태이므로, 일정시간 냉각시키는데, 용융된 수지(130)는 적절한 시간을 냉각한 뒤에 부직포(120)를 부착하여, 부직포(120)가 고온의 수지(130)에 의해 수축하는 것을 방지한다.The cooling step S3 is a step of cooling the resin 130 applied to the paper 110 to 180 ° C or lower. Since the resin 130 extruded by the TiDi 400 is in a molten state at a high temperature, The molten resin 130 adheres the nonwoven fabric 120 after cooling for a suitable period of time to prevent the nonwoven fabric 120 from being shrunk by the high temperature resin 130.

한편, 냉각은 자연 냉각이나 팬(fan, 냉각팬)(미도시) 등에 의해 냉각할 수 있는데, 자연 냉각은 수지(130)가 도포된 종이(110)를 18∼22초, 바람직하게는 20초 정도를 그냥 두어 냉각하는데, 수지(130)가 도포된 종이(110)를 부직포(120)와 합지되기 전까지 상온에서 18∼22초 이동하도록 하여 냉각하는거나, 이 과정에서 팬으로 에어(공기, 바람)를 불어내면 냉각에 필요한 시간을 단축할 수 있다.On the other hand, the cooling can be performed by natural cooling or by a fan (not shown) (not shown), and the natural cooling is performed by heating the paper 110 coated with the resin 130 for 18 to 22 seconds, preferably 20 seconds Cooling is performed by allowing the paper 110 coated with the resin 130 to move for 18 to 22 seconds at room temperature until it is joined with the nonwoven fabric 120. In this process, ) Is blown, the time required for cooling can be shortened.

다음으로, 부직포 공급 및 일체화 단계(S4)는 수지(130)가 도포된 종이(110)에 부직포(120)를 공급하면서 열과 압력으로 일체화하는 단계로, 도2에 도시한 바와 같이, 공급하는 부직포(120)는 자유회전하는 공급롤러(310)에 거치되어 풀리면서 공급되도록 하며, 종이(110)와 부직포(120)의 일체화는 같이 회전하는 히팅롤러(500)와 밀착롤러(510)를 통과하면서 이루어지도록 한다.Next, the nonwoven fabric supplying and integrating step S4 is a step of integrating the nonwoven fabric 120 with heat and pressure while supplying the nonwoven fabric 120 to the paper 110 coated with the resin 130. As shown in FIG. 2, The paper 110 and the nonwoven fabric 120 are integrated with each other by passing through the rotating heating roller 500 and the close contact roller 510 .

추가로, 와인딩 단계(S6)는 제조한 복합부직포(100)를 감아 내는 것으로, 도3에 도시한 바와 같이, 제조하는 복합부직포(100)는 지관(720)이나 롤 등에 일정 길이를 감아 제품으로의 제조가 완료되며, 도2에 도시한 바와 같이, 복합부직포(100)의 와인딩은 모터(710)에 의해 회전하는 와인딩롤러(700)에 지관(720)이나 롤을 설치하고 제조되는 복합부직포(100)을 감고, 일정량이 감기면 감긴 복합부직포(100)를 수거한다.3, the composite nonwoven fabric 100 to be manufactured is wound around a core tube 720 or a roll for a predetermined length to form a product 2, the winding of the composite nonwoven fabric 100 is performed by winding a composite nonwoven fabric (a nonwoven fabric) 710 which is produced by installing a paper tube 720 or rolls on a winding roller 700 rotated by a motor 710 100) is wound around the wound composite nonwoven fabric 100, and a certain amount of the wound composite nonwoven fabric 100 is wound.

이렇게 제조한 복합부직포(100)는 강도가 우수한 종이(110)와 부직포(120)가 견고하게 부착된 구조에 의해서 다양한 분야에 적용이 가능한데, 예를 들어, 단열패널, 냉장고문과 같이 케이스(210)에 발포체(220)(플라스틱 발포체, plastic foaming body, 대표적으로는, 발포폴리우레탄이 있다)을 주입하여 제조하는 단열제품(200)에 적용할 수 있으며, 이 예를 도4의 순서도와 도5를 참고하여 설명하면, 케이스 준비 단계(G1)는 제조하려는 단열 제품 형태를 가지는 케이스(210)를 준비하는 단계로, 케이스(210)는 금속(예를 들어, 스틸)이나 수지(130)의 재료로 성형되어 만들어지며, 제품의 외관의 형태를 가지며, 내부는 공간을 형성한다.The composite nonwoven fabric 100 thus manufactured can be applied to various fields by firmly attaching the paper 110 and the nonwoven fabric 120 having high strength. For example, the case 210, such as the heat insulating panel and the refrigerator door, The present invention can be applied to an adiabatic product 200 manufactured by injecting a foam 220 (a plastic foaming body, typically a foamed polyurethane) into the insulating material 200, The case preparing step G1 is a step of preparing a case 210 having a heat insulating product form to be manufactured. The case 210 is made of a metal (for example, steel) It is molded and made into the shape of the appearance of the product, and the interior forms a space.

그리고 복합부직포 설치 단계(G2)는 케이스(210) 내부에 복합부직포(100)를 설치하는 단계로, 케이스(210) 내부면에 부직포(120) 면이 닿고 종이(110)가 드러나도록 복합부직포(100)를 설치하는데, 케이스(210)의 형태나 형상에 따라 복합부직포(100)는 적절히 재단하여 사용하며, 기본적으로는 복합부직포(100)의 설치에서 접착제를 사용하지 않지만, 케이스(210) 내부면이나 복합부직포(100)에 접착제(바인더)를 도포하여 복합부직포(100)가 떨어지지 않도록 한다.The composite nonwoven fabric installation step G2 is a step of installing the composite nonwoven fabric 100 in the case 210. The composite nonwoven fabric 100 is formed in such a manner that the nonwoven fabric 120 faces the inner surface of the case 210 and the paper 110 is exposed. The composite nonwoven fabric 100 is appropriately cut and used according to the shape and the shape of the case 210. Basically, an adhesive is not used for the installation of the composite nonwoven fabric 100. However, An adhesive (binder) is applied to the surface or composite nonwoven fabric 100 to prevent the composite nonwoven fabric 100 from falling off.

또한, 발포체 포밍 단계(G3)는 케이스(210)에 발포체(220)를을 주입하는 단계로, 포밍하는 폴리우레탄을 케이스(210) 내부을 모두 메우도록 주입하고, 주입이 끝나면 주입 부분도 밀폐하며, 발포체(220)로는 발포폴리우레탄이 있으며, 단열제품(200)의 사양에 따라 그 외의 발포체(220)를 사용할 수 있다.The foam forming step G3 is a step of injecting the foam 220 into the case 210. The foaming polyurethane is injected to fill the inside of the case 210. When the injection is completed, The foam 220 is a foamed polyurethane, and other foam 220 may be used according to the specification of the heat insulating product 200.

한편, 발포체(220)는 케이스(210)에 주입되면서 발포로 인해 부피가 증가하는데, 케이스(210) 내부에서 부피가 증가하여도, 복합부직포(100)가 케이스(210)의 형태를 단단히 잡아주기 때문에 케이스(210)의 휨이나 부분 돌출과 같은 변형을 방지한다.Meanwhile, the foam 220 increases in volume due to foaming as it is injected into the case 210. Even if the volume of the foam 210 increases in the case 210, the composite nonwoven fabric 100 may securely hold the shape of the case 210 Thereby preventing deformation such as warping or partial protrusion of the case 210. [

마지막으로, 경화 단계(G4)는 케이스(210)에 주입된 발포체(220)를 시간을 두어 경화하여 단열제품(200)을 완성하는 단계로, 케이스(210)에 주입된 발포체(220)는 대부분 일정 시간을 두면 경화하며, 이 경화를 통해 단열제품(200)이 완성되고, 또한, 이 단열제품(200)이 제품의 부품에 적용되기 위해서 기타 필요한 가공이나 처리는 다르게 진행된다.Lastly, the curing step G4 is a step of curing the foamed material 220 injected into the case 210 for a predetermined time to complete the heat insulating product 200. The foamed material 220 injected into the case 210 is mostly The cured product is cured by a certain amount of time. The cured product completes the heat insulating product 200, and other necessary processing and processing are performed differently in order for the heat insulating product 200 to be applied to parts of the product.

이와 같이, 복합부직포(100)가 단열제품(200)의 제조에 사용됨에 따라, 발포체(220)의 주입에 따른 부피 및 압력 증가에도 케이스(210)가 변형을 방지하는 있으므로, 발포체(220) 주입의 최대화를 통해서 단열성이 우수한 단열제품(200)을 제공할 수 있으며, 복합부직포(100)의 제조 과정에서 냉각 단계(S3)의 포함으로, 고온으로 압출된 수지(130)를 저융점 섬유의 부직포(120)와 바로 부착하지 않으므로, 부직포의 수축 및 그 수축으로 인한 변형을 방지할 수 있는 특징이 있다.As the composite nonwoven fabric 100 is used for manufacturing the heat insulating product 200, the case 210 is prevented from being deformed even when the volume and the pressure increase due to the injection of the foam 220, It is possible to provide the adiabatic product 200 having excellent thermal insulation through maximization of the thermal expansion coefficient of the nonwoven fabric 100. The resin 130 extruded at a high temperature in the process of manufacturing the composite nonwoven fabric 100, Since it is not directly attached to the nonwoven fabric 120, it is possible to prevent the nonwoven fabric from shrinking and deformation due to its shrinkage.
