상기 판재(100)는 상단에 알루미늄시트(110)가 형성되고, 상기 알루미늄시트(110)의 하단에는 외측라이너(120)가 형성되며, 상기 외측라이너(120)의 하단에는 골심지(130)가 형성되고, 상기 골심지(130)의 하단에는 내측라이너(140)가 형성되며, 상기 내측라이너(140)의 하단에는 철재시트(150)가 형성되되, The plate 100 is formed of an aluminum sheet 110 at the top, the outer liner 120 is formed at the lower end of the aluminum sheet 110, the core core 130 is formed at the lower end of the outer liner 120. The inner liner 140 is formed at the lower end of the corrugated core 130, and the steel sheet 150 is formed at the lower end of the inner liner 140.

상기 외측라이너(120), 골심지(130) 및 내측라이너(140)는 펄프 100중량부 당 마 40 중량부 및 목화 10 중량부로 구성된다. The outer liner 120, the core core 130 and the inner liner 140 is composed of 40 parts by weight and 10 parts by weight of cotton per 100 parts by weight of pulp.

상기 판재(100)는 모서리부분을 사선으로 절단하고, 이를 연결하여 관형상으로 형성한다. The plate 100 is cut in the corner portion diagonally, and connected to form a tubular shape.

상기 판재(100)는 하단의 철재시트(150)가 내부로 향하도록 형성하여 관의 내벽은 철재시트(150)가 관의 외벽은 알루미늄시트(110)가 위치하도록 형성된다. The plate 100 is formed such that the lower steel sheet 150 is directed toward the inside, so that the inner wall of the tube is an iron sheet 150 and the outer wall of the tube is an aluminum sheet 110.

상기 판재(100)의 가운데에 형성되는 골판지(200)는 외측라이너(120), 골심지(130) 및 내측라이너(140)로 구성된다. Corrugated cardboard 200 formed in the center of the plate 100 is composed of the outer liner 120, the corrugated core 130 and the inner liner 140.

상기 골심지(130)는 일반적으로 형성하는 골판지(200)의 제조과정과 동일하게 단면형상을 기어형상으로 연속하여 접어서 공간부가 형성되도록 제작한다.The corrugated core 130 is manufactured so as to form a space portion by continuously folding the cross-sectional shape in a gear shape in the same manner as the manufacturing process of the corrugated cardboard 200 to be generally formed.

상기 골심지(130)는 다단으로 형성될 수 있는데, 각각의 골심지(130)의 사이에는 내측라이너(140)를 형성하여 다단으로 형성할 수 있다. The corrugated core 130 may be formed in multiple stages, and the inner liner 140 may be formed between the corrugated cores 130 and formed in multiple stages.

상기 내,외측라이너(140,120) 및 골심지(130)는 모두 펄프 100중량부당 마 40 중량부, 목화 10 중량부를 혼합하여 형성한다.The inner and outer liners 140 and 120 and the core wick 130 are formed by mixing 40 parts by weight of hemp and 10 parts by weight of cotton per 100 parts by weight of pulp.

상기 마(麻)는 삼베 등의 원료인 삼을 가리키는 말로, 섬유질이 잘 발달하여 펄프와 같이 페이퍼를 구성할 경우 더욱 견고하고 가공성을 좋게 한다. The hemp refers to hemp which is a raw material such as burlap, and the fiber is well developed to form a paper like pulp, making it more robust and workable.

상기 목화는 목화속 식물에서 섬유를 뽑아서 만든 것으로, 섬유질이 잘 발달되어 마와 비슷한 역할을 수행하나, 마보다 섬세하고 부드러워서 갈라지거나 쉽게 찢어지는 것을 방지할 수 있다.The cotton is made by pulling the fibers from the plant in the cotton, the fiber is well developed and plays a role similar to hemp, it is more delicate and softer than hemp can prevent cracking or easy tearing.

상기 내,외측라이너(140,120) 및 골심지(130)를 제조하는 방법은 펄프 100중량부당 마 40중량부, 목화 10중량부로 페이퍼를 형성하고, 상기 형성된 페이퍼는 바트에 형성된 코팅액으로 코팅한 후에 에어스프레이(74)로 에어커팅 후 열풍건조하여 형성한다.The inner and outer liner (140, 120) and the core wick 130 is a method of manufacturing a paper by 40 parts by weight per 100 parts by weight of pulp, cotton 10 parts by weight of the cotton, the formed paper is coated with a coating liquid formed in the bart air spray After the air cutting with 74 to form a hot air drying.

즉, 상기 골판지(200)를 제조하는 방법은 펄프 100중량당 마 40중량부 및 목화 10중량부로 형성된 페이퍼를 롤형태로 준비하는 준비단계(51)와; That is, the method for manufacturing the corrugated cardboard 200 is prepared step (51) for preparing a roll of paper formed of 40 parts by weight and 10 parts by weight of cotton per 100 weight pulp;

상기 페이퍼를 로울러(72)에 의해 코팅액이 포함된 바트(73)를 통과시키는 코팅단계(52)와;A coating step (52) of passing the paper through the bart (73) containing the coating liquid by the roller (72);

상기 코팅단계(52) 후에 에어스프레이(74)로 표면을 에어커팅하는 표면평탄단계(53)와;A surface leveling step 53 of air cutting the surface with an air spray 74 after the coating step 52;

상기 표면평탄단계(53) 후에 건조기(75)에서 열풍건조하여 롤페이퍼(70)를 완성하는 열풍건조단계(54)와; A hot air drying step 54 of completing the roll paper 70 by hot air drying in the dryer 75 after the surface flattening step 53;

상기 롤페이퍼(70)를 3단으로 형성된 롤에 각각 거취하고, 압착롤로 통과시키되, 가운데의 롤페이퍼(70)는 기어형태롤을 형성시켜 절곡하여 압착롤에 삽입될 수 있도록 형성하는 압착단계(55)로 구성되는 것을 특징으로 한다.
The roll paper 70 is taken in rolls formed in three stages, respectively, and passed through a pressing roll, wherein the middle roll paper 70 forms a gear-shaped roll to be bent to be inserted into the pressing roll. And 55).

상기 코팅액은 물 100중량부당 분산제 1중량부, 수산화알루미늄 40중량부, 실리카 5 중량부, 산화티타늄 10 중량부, 폴리우레탄 20 중량부 및 소포제 1 중량부를 혼합하여 형성한다. The coating solution is formed by mixing 1 part by weight of a dispersant, 40 parts by weight of aluminum hydroxide, 5 parts by weight of silica, 10 parts by weight of titanium oxide, 20 parts by weight of polyurethane, and 1 part by weight of an antifoaming agent.

상기 코팅액에는 난연재로 알려져 있는 수산화알루미늄과 실리카로 형성되어 난연효과가 발생할 수 있도록 형성된다. The coating solution is formed of aluminum hydroxide and silica, which is known as a flame retardant, and is formed to cause a flame retardant effect.

상기 각각의 수치한정은 공조덕트를 제연덕트로 활용할 수 있도록 골판지(200)가 열에 강한 난연성을 띄기 위해서 한정된 것이다.Each numerical limitation is limited so that the corrugated cardboard 200 exhibits flame retardant resistance to heat so that the air conditioning duct can be utilized as a ventilation duct.

상기 수산화알루미늄의 양을 40중량부 이상 넣을 경우에는 제품성과 가공성이 떨어지고, 이하를 넣을 경우에는 난연효과가 떨어진다. When the amount of the aluminum hydroxide is added 40 parts by weight or more, the productability and workability are inferior, and when the amount is added, the flame retardant effect is inferior.

상기 실리카를 5 중량부이상 넣을 경우에는 가공시 가루가 날려서 제품성이 떨어지게 되고, 이하를 넣을 경우에는 역시 난연효과가 떨어진다.
When the silica is added in 5 parts by weight or more, the powder is blown off during processing, resulting in poor productability.

이하, 본 발명의 바람직한 실시예로 형성된 골판지로 형성된 공조덕트의 제조방법 및 작용을 설명하면 다음과 같다.Hereinafter, the manufacturing method and operation of the air conditioning duct formed of corrugated cardboard formed by the preferred embodiment of the present invention.

상기 골판지(200)의 한쪽 면에는 알루미늄시트(110)를 접착하고, 다른 면에는 철재시트(150)를 접착한다. One side of the corrugated cardboard 200 is bonded to the aluminum sheet 110, the other side is bonded to the steel sheet 150.

이후, 일정한 크기로 절단하고, 양 측면은 대각선으로 절단한 후에 서로 접착하여 사각관형상으로 형성한다. Then, cut to a constant size, both sides are cut diagonally and then bonded to each other to form a square tube shape.

이때, 철재시트(150)가 내부에 형성될 수 있도록 형성하고, 각각의 절단면을 접착할 때 연결구 등을 활용할 수 있다. In this case, the steel sheet 150 may be formed to be formed therein, and a connector or the like may be utilized when bonding the respective cut surfaces.

상기 골판지(200)의 내부에는 공간이 많이 형성되고, 페이퍼에는 목화와 마가 형성되므로, 열전도율은 공기가 0.024(W/mK) 이고, 목화 및 마는 0.03(W/mK) 밖에 되지 않으므로 열전도율이 떨어져서 보온성이 강하다. Since a lot of space is formed inside the cardboard 200, and cotton and hemp are formed on the paper, the thermal conductivity is 0.024 (W / mK) of air, and cotton and hemp are only 0.03 (W / mK). This is strong.

또한, 본 발명의 골판지(200)는 코팅제에 의해서 내열이 180℃까지 가능하고, 내벽이 철재시트(150)로 형성되기 때문에 제연덕트로 활용이 가능하다.
In addition, the corrugated cardboard 200 of the present invention can be used as a dehumidification duct because the heat resistance is up to 180 ℃ by the coating agent, the inner wall is formed of the steel sheet 150.

본 발명은 첨부된 도면을 참조하여 바람직한 실시예를 중심으로 기술되었지만, 당업자라면 이러한 기재로부터 후술하는 특허청구범위에 의해 포괄되는 본 발명의 범주를 벗어남이 없이 다양한 변형이 가능하다는 것은 명백하다.While the invention has been described with reference to the accompanying drawings, preferred embodiments of the invention, it will be apparent to those skilled in the art that various modifications are possible without departing from the scope of the invention covered by the following claims.
