Description

크라프트 지대용 고지 재활용 포장용지의 제조방법{Manufacturing method of the old paper-recycled packaging paper using for a kraft paper sacks}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a recycled packaging paper,

본 발명은 크라프트 지대용 포장용지의 제조방법에 관해 보다 상세하게는 골판지 고지(故紙)를 재활용한 포장용지의 제조방법에 관한 것이다. More particularly, the present invention relates to a method for producing a wrapping paper for recycled corrugated cardboard paper.

일반적으로, 포장용지로는 크라프트지(kraft paper)가 주로 이용되는데, 이것은 지금까지 한겹뜨기(singleply-forming) 방식에 의해 제조됨으로써 종이의 양면이 동일한 원료(한겹)로 구성되어 용도가 제한적이고, 또한 크라프트지의 원료인 천연펄프는 전량 수입에 의존하고 있는 실정이므로 원료의 확보 및 제품의 제조에 많은 문제점이 있었다.Generally, kraft paper is mainly used as a wrapping paper. Since kraft paper is produced by a single-ply forming method, both sides of the paper are made of the same raw material (single layer) In addition, since natural pulp, which is a raw material of kraft paper, is entirely dependent on imports, there are many problems in securing raw materials and manufacturing products.

따라서, 천연펄프 대신 고지(故紙 : old paper 또는 old corrugated container)를 재활용하여 여러겹뜨기(multiply-forming) 종이 제조 방식으로 포장용지를 제조하면, 용도가 다양해질 뿐만 아니라 각 층간 저평량화에 의한 탈수능력 증대, 저농도작업에 의한 지합 개선으로 인쇄적성 향상, 여러겹뜨기에 의한 강도 향상 및 치수안정성 개선, 등으로 자원절약, 원가절감, 에너지절감 및 생산성향상을 도모할 수 있을 것이다.Therefore, when packaging paper is produced by multiply-forming paper manufacturing method by recycling old paper or old corrugated container instead of natural pulp, not only the applications are diversified, It will be possible to save resources, reduce cost, save energy, and improve productivity by improving durability and improving density by low concentration work, improving strength by multi-folding, and improving dimensional stability.

본 발명의 목적은 고지를 재활용하여 비용을 절감하면서도 강도 및 치수안정성이 우수한 여러겹뜨기 재활용 크라프트 지대용 포장용지의 제조방법을 제공하는 데 있다.It is an object of the present invention to provide a method for manufacturing a wrapping paper for a multi-folding recycled kraft paper having high strength and dimensional stability while reducing costs by recycling paper waste.

본 발명에 따르면, 크라프트 지대용 고지 재활용 포장용지는 펄프 또는 골판지 고지(OCC : old corrugated container)를 물과 적당량 혼합하여 3 ~ 15%의 농도로 펄핑(pulping)하는 단계와, 상기 펄핑된 재료를 크리나, 스크린, 리파이나를 통하여 이물질 제거, 분산 및 리파이닝 처리하는 단계와, 상기 리파이닝 처리된 재료를 원료 저장조에서 혼합하여 사이즈제, 정착제, 건조 지력증강제 및 기타 특수한 목적용 약품 및 염료를 용도에 따라 조정하여 첨가하는 단계 및 이를 60 ~ 110g/m2의 여러겹뜨기로 형성하는 단계로 제조된다.According to the present invention, the paper recycled paper for reclaiming paper of the Kraft Zone is produced by mixing pulp or old corrugated container (OCC) with water in an appropriate amount and pulping at a concentration of 3 to 15% Removing, dispersing and refining the refined material through a screen, a screen, and a refiner; mixing the refined material in a raw material reservoir to prepare a sizing agent, a fixing agent, a drying agent strength enhancer, By weight and adjusting it and forming it into several layers of 60 to 110 g / m < 2 & gt ;.

구체적으로 말해, 주원료의 100 건조 중량 %에 대하여 사이즈제 0.1 ~ 0.6 중량 %, 정착제 0.05 ~ 0.3 중량 %, 건조 지력증강제 0.1 ~ 2.0 중량 %를 첨가하여 지료를 조성하고 이를 초지기의 각 헤드 박스에 유입시켜 여러겹의 습지를 제조하고 압착 및 건조시켜 종이를 제조하는 것이다.Specifically, 0.1 to 0.6% by weight of a sizing agent, 0.05 to 0.3% by weight of a fixing agent, and 0.1 to 2.0% by weight of a dry strength agent are added to 100% by dry weight of the main raw material, To produce a plurality of layers of wetlands, and to pressurize and dry the paper to produce paper.

이하, 본 발명을 구체적으로 설명한다.Hereinafter, the present invention will be described in detail.

본 발명에 따른 제조방법은 종래의 방법에서처럼 천연펄프를 100% 사용하지 않고 고지를 대부분 사용하기 때문에 고지중의 이물질 제거 및 리파이닝 처리하고 표면층에 인쇄 등 요구 특성에 따라 물리적으로 이물질을 분산시키는 과정이 요구된다.Since the manufacturing method according to the present invention uses most of the high-grade paper without using 100% of the natural pulp as in the conventional method, the process of removing the foreign matter in the high paper and refining the paper and dispersing the foreign material physically according to the required characteristics such as printing on the surface layer Is required.

이 때, 본 발명에서 사용할 수 있는 사이즈제로는 강화 로진 사이즈제(rosin size), 에멀젼 사이즈제(emulsion size) 및 합성 사이즈제, 섬유 수지계 사이즈제, 중성 사이즈제 등이며, 정착제는 황산 알루미늄 (aluminium sulfate), 폴리알루미늄 클로라이드 (polyaluminium chloride), 폴리알루미늄 하이드록시클로로설페이트 (polyaluminium hydroxychlorosulfate) 등이며, 건조 지력증강제는 폴리아크릴아마이드(polyacrylamide), 폴리비닐 알코올(polyvinyl alcohol), 생전분, 양성전분, 효소처리전분, 폴리에틸렌 옥사이드(polyethylene oxide) 등이다.At this time, the sizing agent which can be used in the present invention is rosin size, emulsion size and synthetic sizing agent, fiber resin sizing agent and neutral sizing agent, and the fixing agent is aluminum sulfate ( aluminum sulfate, polyaluminium chloride and polyaluminium hydroxychlorosulfate. The dry strength agent may be selected from the group consisting of polyacrylamide, polyvinyl alcohol, starch, starch, Enzyme treated starch, and polyethylene oxide.
