그러므로 가볍고 견고하여 다루기가 쉽고, 섬유 적층 소재로 만들어져 내구성과 가공성이 우수하며, 특히 가격이 싼 이유로 건축공사 비용의 절감은 물론, 환경친화형 제품으로 사용 이후 폐기물도 재활용이 되는 휀스가 절실하게 필요한 실정이었다.Therefore, it is light and strong, easy to handle, and made of fiber laminated material, which is excellent in durability and workability. Especially, due to the low price, it is necessary to reduce the cost of construction work and eco-friendly products. It was a situation.
이에 본 발명은 상기한 바와 같은 종래의 문제점을 해소시키기 위하여 안출된 것으로, 섬유폐기물의 폴리에스터 섬유와 기타 섬유를 합성하여 생산한 부직포를 재단하면서 열경화성 요소수지를 양면에 도포하고, 이를 건조한 후 다수 적층하면서 가열 가압 성형하여 냉각한 상태에서 재단 가공하여 휀스를 완성하도록 함으로써 섬유 적층 소재로 만들어져 내구성과 가공성이 우수하며, 가격이 싸서 건축공사 비용의 절감은 물론, 환경친화형 제품으로 사용 이후 폐기물도 재활용이 가능하도록 한 환경친화형 신소재 섬유를 이용한 휀스의 제조방법을 제공하는 것을 그 목적으로 한다.Therefore, the present invention was devised to solve the conventional problems as described above, while applying the thermosetting urea resin on both sides while cutting the nonwoven fabric produced by synthesizing the polyester fibers and other fibers of the fiber waste, and dried many of them It is made of fiber laminated material, which is made of fiber lamination material to be finished by cutting and heat processing under cooling and molding by lamination, and it is excellent in durability and workability. It is an object of the present invention to provide a method for manufacturing a fence using environmentally friendly new material fiber which enables recycling.
상기 목적을 달성하기 위한 본 발명의 환경친화형 신소재 섬유를 이용한 휀스의 제조방법은,Method for producing a fence using the environmentally friendly new material fibers of the present invention for achieving the above object,
섬유 제조업체 또는 봉제업체와 섬유 가공업체에서 제품생산 공정 중에 1년에 486,000톤 정도 발생하는 섬유폐기물을 소재로 한다.Textile manufacturers or sewing companies and textile processing companies use textile waste, which generates about 486,000 tons per year during the production process.
상기 소재 중 폴리에스터 섬유 75%와 기타 섬유 25%를 합성하여 신소재섬유 방음벽 제품 규격에 따른 60∼200Kg/m3의 밀도가 되도록 두께 8mm의 부직포를 생산한다.75% of the polyester fiber and 25% of the other materials are synthesized to produce a nonwoven fabric having a thickness of 8 mm so as to have a density of 60 to 200 Kg / m 3 according to the new material fiber soundproof wall product standard.
폭 1,300mm 길이 25m, 두께 8mm의 규격으로 생산된 부직포를 제품의 규격별로 재단하고, 재단된 부직포의 접착력을 강화하기 위하여 환경친화적인 열경화성요소수지를 비롯하여 메라민 또는 아크릴수지를 M2당 50g 정도로 양면에 도포한다.In order to cut nonwoven fabric produced in the specification of width 1,300mm length 25m and thickness 8mm according to the product's specifications and to strengthen the adhesive force of the cut nonwoven fabric, both sides of the environmentally friendly thermosetting urea resin, melamine or acrylic resin are about 50g per M 2 Apply to
도포한 부직포를 투입온도 100℃, 건조온도 120℃, 인출온도 100℃의 간접열을 발생하는 건조기에서 함수량이 15% 이하가 되도록 완전히 건조한다.The coated nonwoven fabric is completely dried so that the water content is 15% or less in a dryer that generates indirect heat of 100 ° C, 120 ° C and 100 ° C withdrawal temperature.
건조된 소재는 신소재 섬유 휀스 생산을 위하여 소재 8mm 제품 9장을 적층한 후, 성형 몰드 위에 열판온도 190 - 200℃, 양쪽이 90 - 100Kg/Cm2의 압력으로 열압 성형프레스에서 제품두께 1 Cm당 1분의 시간으로 가압 성형하여 성형프레스에서 두께 8mm의 소재가 1mm 정도로 줄어들도록 한다.The dried material is laminated with 9 sheets of 8mm material for the production of new material fiber fence.Then, the hot plate temperature is 190-200 ℃ on both sides of the mold and the pressure is 90-100Kg / Cm 2 on the mold. Press molding by the time of 1 minute to reduce the material of 8mm thickness to about 1mm in the molding press.
상기의 가압 성형을 할 때 온도와 압력 및 시간에 의하여 합성수지의 일부가 녹으면서 섬유 소재가 용융 성형되고, 이 경우에 발생하는 가스에 의해 내부가 폭발하는 등의 안전 사고를 방지하기 위하여 성형프레스에 가스배출장치를 부착하여 초기제품 투입 후 1분에 3∼5회 가스를 배출하는 압력조절이 이루어지도록 한다.In the pressure molding, the fiber material is melt-molded by melting part of the synthetic resin by temperature, pressure and time, and in order to prevent safety accidents such as internal explosion by gas generated in this case, A gas discharge device is attached to control the pressure to discharge the gas 3 to 5 times a minute after the initial product is added.
성형이 완료된 제품의 뒤틀림과 변형을 방지하기 위하여 30℃ 이하의 온도에서 15Kg/Cm2이상의 압력이 주어지도록 한 상태에서 표면온도가 30℃ 이하가 되도록 냉각 몰드가 있는 프레스에서 10분 이상 급속 냉각시킨다.In order to prevent warping and deformation of the finished product, rapid cooling is carried out for 10 minutes or more in a press with a cooling mold at a surface temperature of 30 ° C or lower while applying a pressure of 15Kg / Cm 2 or higher at a temperature of 30 ° C or lower. .
상기의 급속 냉각이 완료된 제품을 제품 규격별로 원형 다이아몬드 톱으로 재단 가공하도록 함으로써 환경친화형 신소재 섬유 휀스 제품을 완성하도록 함을 특징으로 한다.The rapid cooling is completed by cutting the product with a circular diamond saw for each product specification characterized in that to complete the environmentally friendly new material fiber fence products.
이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.
본 발명에 따른 환경친화형 신소재 섬유를 이용한 휀스의 제조방법은,Method for producing a fence using environmentally friendly new material fibers according to the present invention,
합성섬유의 폐기물을 가로세로 5Cm의 크기로 절단하고 그 올을 풀어서 환경친화형 신소재 섬유 휀스를 제조하기 위하여 폴리에스터 75%, 나일론 및 아크릴 등의 기타 섬유 25%의 구성비와 8mm의 두께가 유지되는 고밀도 부직포를 생산하는 과정과,The composition ratio of 75% polyester, 25% other fibers such as nylon and acrylic, and a thickness of 8mm are maintained to cut the waste of synthetic fiber to a size of 5 cm in width and loosen it to produce new eco-friendly fiber fibers. Process of producing high density nonwoven fabric,
여기서 상기 섬유의 구성비는 폴리에스터 50%, 기타 섬유 50%의 비율도 가능하지만 프레스 성형을 할 때 압력이 120Kg/Cm2로 높아야 하고, 온도도 200℃ 이상으로 높아야 하기 때문에 제품의 표면이 타고 경제적이지 못하므로 상기 폴리에스터 75%, 나일론 및 아크릴 등의 기타 섬유 25%의 구성비가 바람직하다.The composition ratio of the fiber may be 50% polyester and 50% other fibers, but the pressure should be as high as 120Kg / Cm 2 when press molding, and the temperature should be higher than 200 ° C. As such, the composition ratio of 75% polyester, 25% other fibers such as nylon and acrylic is preferred.
폭 1,300mm 길이 25m, 두께 8mm의 규격으로 생산된 부직포를 제품의 규격별로 재단하는 과정과,The process of cutting the nonwoven fabric produced in the size of 1,300mm width 25m length and 8mm thickness according to the product standard,
상기의 재단된 부직포에 제품의 접착력과 강도유지를 위하여 일반적인 열경화성수지인 메라민 또는 아크릴 수지도 사용이 가능하지만 환경친화적인 열경화성 요소수지를 m2당 50g의 수지를 스프레이로 양면에 도포 하는 과정과,In order to maintain the adhesive strength and strength of the product on the cut nonwoven fabric, general thermosetting resin, such as melamine or acrylic resin can be used, but the process of applying 50g of resin per m 2 to each side by spraying with environmentally friendly thermosetting resin,
상기의 요소수지 외에 메라민 또는 아크릴수지를 도포하여도 무방하다.In addition to the urea resin described above, a melamine or an acrylic resin may be applied.
여기서 상기의 열경화성 수지를 m2당 50g 이상 도포 할 경우 프레스 성형시 수지가 녹아서 밀려나오고 제품상태가 너무 단단해져서 가공성이 떨어지므로 m2당50g 정도의 수지를 도포하는 것이 바람직하다.Here, since the workability haejyeoseo out the resin press molding melt state pushed product becomes too hard to fall When applying the thermosetting resin at least 50g per m 2 is preferably coated with a resin of about 50g per m 2.
상기의 제품의 접착력과 표면색상과 박리 등의 불량방지를 위하여 수지가 도포된 부직포를 투입온도 100℃, 건조온도 120℃, 인출온도 100℃의 간접열을 발생하는 건조기에서 함수량이 15% 이하가 되도록 건조하는 과정과,In order to prevent defects such as adhesion, surface color and peeling of the above products, the resin-coated nonwoven fabric has a water content of 15% or less in a dryer that generates indirect heat of 100 ° C, 120 ° C and 100 ° C withdrawal temperature. Drying process if possible,
여기서 상기 부직포의 함수량이 15% 이상이 되면 수분으로 인한 얼룩이 제품 표면에 생기고 제품 결합력이 떨어지는 문제점이 있으므로 함수량이 15% 이하가 되도록 한다.In this case, when the water content of the nonwoven fabric is 15% or more, stains due to moisture are generated on the surface of the product and the product bonding strength is lowered, so that the water content is 15% or less.
완전히 건조된 부직포 소재를 8mm 소재 9장을 한 장씩 적층하면서 몰드(금형) 위에 열판의 표면온도가 190-200℃가 되도록 하고, 프레스의 압력이 90 - 100Kg/Cm2로 하여 제품두께 평균 1Cm당 1분의 시간으로 성형하여 두께 8mm의 소재가 1mm 정도로 줄어들도록 하는 과정과,Laminate the dried non-woven fabrics with 9 sheets of 8mm materials one by one and make the surface temperature of the hot plate be 190-200 ℃ on the mold (mold), and press pressure is 90-100Kg / Cm 2 . Molding in 1 minute to reduce the thickness of 8mm material to about 1mm,
상기의 가열 압착 성형에 의하여 환경친화형 신소재 섬유 휀스를 9mm 정도 두께의 제품으로 제작할 수 있도록 한다.By heat-compression molding, the environmentally friendly new material fiber fence can be manufactured into a product having a thickness of about 9 mm.
상기의 열을 가하는 상태에서 성형할 경우 특히 PTA 섬유의 경우 140 - 160℃ 온도의 용융 과정에서 포화증기와 가스가 방출되므로 일반적인 가스배출장치를 반드시 부착하여 제품 투입 후 초기 1분에 3∼5회 가스를 배출시키는 압력조절을 수행하도록 하여 내부의 압력으로 인해 폭발이 발생하는 등의 안전사고를 방지할 수 있도록 하는 과정과,In the case of molding in the state of applying the above heat, especially in case of PTA fiber, saturated steam and gas are released during the melting process at 140-160 ℃, so a general gas discharge device must be attached and 3 ~ 5 times in the first minute after the product is put in. To control the discharge of gas to prevent safety accidents such as explosion due to internal pressure;
상기의 성형이 완료된 제품에 대해 30℃이하의 온도에서 15Kg/Cm2이상의 압력이 주어진 상태에서 냉각 몰드(금형) 표면온도가 30℃ 이하가 되도록 급속 냉각시켜 생산제품의 뒤틀림과 변형을 방지하도록 하는 과정과,For the finished product, the cooling mold (mold) surface temperature is 30 ℃ or less under a pressure of 15Kg / Cm 2 or more at a temperature of 30 ℃ or less to prevent warping and deformation of the product. Process,
여기서 압력이 없는 자연상태이거나 급속 냉각을 하지 않을 경우 소재의 관성이 제 각각으로 다른 사유로 뒤틀림과 변형이 발생하는 문제점이 있게 된다.If there is no natural pressure or rapid cooling, there is a problem that the inertia of the material is distorted and deformed due to different reasons.
