The water-based coating composition for the paper according to the present invention uses an aqueous solvent, while not only satisfying the water resistance, oil resistance, moisture permeability, dissociation degree, coating properties, anti-blocking properties, and heat sealing properties at the same time very well, but also providing the effect of improving the paper strength to be useful as an aqueous coating solution for the paper, such as food packaging paper, industrial product packaging paper, paper bags, paper boxes, corrugated cardboard, paper angles, paper pallets and the like.

Description

히트 실링, 안티블로킹성 등을 만족하는 종이용 수성 코팅 조성물 {Water-based coating composition for paper that satisfies heat sealing and anti-blocking properties}Water-based coating composition for paper that satisfies heat sealing and anti-blocking properties {Water-based coating composition for paper that satisfies heat sealing and anti-blocking properties}

본 발명은 내수도, 내유도, 투습도, 해리도, 코팅성, 안티블로킹성 및 히트 실링(heat sealing)을 동시에 매우 우수하게 만족할 뿐만 아니라, 종이에 코팅시 종이의 강도 역시 향상 효과가 있는 종이용 수성 코팅 조성물에 관한 것이다.The present invention not only satisfies water resistance, oil resistance, moisture permeability, dissociation degree, coating property, anti-blocking property and heat sealing at the same time very excellently, but also improves the strength of paper when coated on paper. It relates to an aqueous coating composition.

일반적으로 제과, 제빵, 축산물, 농산물, 수산물 등의 내용물들을 저장 또는 운반하기 위하여 제작되는 포장재는 대부분 종이, 골판지, 스티로폼 등 여러가지 재질로 제작하여 사용되고 있다. In general, packaging materials manufactured to store or transport contents such as confectionery, baking, livestock products, agricultural products, and marine products are mostly made of various materials such as paper, corrugated cardboard, and Styrofoam.

이와 같은 포장재를 스티로폼으로 제작할 경우에는 방수 및 보온, 보냉효과는 물론, 외부로부터 가해지는 충격으로부터 내부에 보관된 내용물을 보호할 수 있지만, 성형 제작된 박스체가 내용물을 담기 위해 일정한 부피를 유지하도록 압축 성형되는 것이므로, 보관과 운반에 많은 비용이 소요되고, 재활용이 불가능하여 환경 오염 문제가 있다.When such a packaging material is made of Styrofoam, it is possible to protect the contents stored inside from external impact as well as waterproof, thermal insulation, and cooling effects, but the molded box is compressed to maintain a constant volume to contain the contents. Since it is molded, it costs a lot for storage and transportation, and it is impossible to recycle, so there is a problem of environmental pollution.

반면, 종이와 골판지로 제작되는 포장재는 제작이 용이하고 펼쳐서 적층한 상태로 보관하다가 사용시 간단하게 조립하여 사용됨으로써, 물류 비용을 크게 절감시킬 수 있다는 장점은 있지만, 그 구성재료가 종이의 재질이기 때문에 방습성, 내수성, 내유성 등의 물성이 떨어지는 문제점이 있다. On the other hand, packaging materials made of paper and corrugated cardboard are easy to manufacture, and they are stored in an unfolded and stacked state, and then simply assembled and used when used, which has the advantage of greatly reducing logistics costs. There is a problem in that physical properties such as moisture resistance, water resistance, oil resistance are inferior.

종이와 골판지를 이용한 박스는 물성을 위하여 내부에 기능성 필름을 덧붙이는 경우 재활용을 위하여 필름층과 종이물질을 분리할 때, 그 분리가 쉽지 않아 쉽게 재활용을 할 수 없으며, 종이와 골판지에 붙여야 되는 기능성 필름이 낭비되는 문제점이 있었다.When a functional film is added to the inside of a box using paper and corrugated cardboard for physical properties, when the film layer and the paper material are separated for recycling, the separation is not easy, so it cannot be easily recycled. There was a problem that the film was wasted.

종이에 코팅액을 코팅을 한 다음 롤 형태로 보관하게 되는데, 이때 사용자는 롤에서 종이를 펼칠때 블로킹 현상이 발생하면 생산에 문제가 발생할 수 있어, 안티블로킹 효과를 충분히 만족할 필요성이 있다.After the coating solution is coated on paper, it is stored in a roll form. In this case, if a blocking phenomenon occurs when the user unfolds the paper from the roll, production problems may occur, so there is a need to sufficiently satisfy the anti-blocking effect.

최근 배달 수요가 급증하고 있어, 별도의 스키터나 접착제 없이 열접착기를 이용해 간단히 밀봉할 수 있는 물성이 대두되고 있다는 점에서, 종이용 코팅액 역시 히트 실링(heat sealing)을 만족할 경우 사용자의 만족도를 높일 수 있다.Recently, as the demand for delivery is rapidly increasing, the physical properties that can be easily sealed using a heat bonding machine without a separate skiter or adhesive are emerging. If the coating solution for paper also satisfies heat sealing, user satisfaction can be increased. have.

최근 신선식품 새벽배송이나 당일배송 이용자가 급증하면서 관련시장이 급성장세이지만 배송과정에서 스티로폼 박스나 은박보냉팩, 에어백, 포장비닐 등 1회용품이나 재활용 불가 포장재가 과도하게 사용되는 문제점이 있다. 폐기되는 국내 식품포장재가 160만 톤에 이르는데, 전량 재활용이 가능하다면 포장재 Kg당 약 3 Kg의 온실가스 감축효과가 있다는 연구결과를 비추어 보면 사용 후 재활용이 가능한 즉, 재활용성 소재로 된 식품포장재가 개발될 경우 결국 국내기준 연간 480만 톤에 이르는 거대한 양의 온실가스감축이 가능하다는 측면에서 매우 유망한 해결방안으로 대두되고 있다Recently, as the number of users for early morning delivery or same-day delivery of fresh food has increased rapidly, the related market is rapidly growing, but there is a problem in that single-use or non-recyclable packaging materials such as Styrofoam boxes, silver foil cold packs, air bags, and plastic packaging materials are used excessively during the delivery process. Domestic food packaging materials that are discarded amount to 1.6 million tons, and if the entire amount is recycled, it is possible to reduce GHG emissions by about 3 kg per kg of packaging material. In light of the research results, food packaging materials made of recyclable materials can be recycled after use. If developed, it is emerging as a very promising solution in that it will eventually reduce a huge amount of greenhouse gas emissions up to 4.8 million tons per year in Korea.

현재 국내에서 생산되는 식품 포장재의 경우, 유기용매에 고분자물질을 녹여서 종이 또는 박스 위에 코팅하는 방법은 우수한 물성과 우수한 작업성 때문에 선호하는 방법이기는 하지만 유기용제 사용시 배출되는 유기물질들로 인해 대기오염의 주요인으로 인식되고 있으며 인체에 유해하며 가연성이기 때문에 화재의 위험성이 높은 실정이다.In the case of food packaging materials currently produced in Korea, the method of dissolving a polymer material in an organic solvent and coating it on paper or box is the preferred method because of its excellent properties and excellent workability, but it is a method of reducing air pollution due to the organic substances emitted when using organic solvents. It is recognized as a major cause, is harmful to the human body, and has a high risk of fire because it is flammable.

이러한 단점을 해결하기 위한 방법으로 제안되는 것들 중 하나가 물을 용매 혹은 분산매로 사용하여 제조한 수성 코팅제를 사용하는 것으로 유기용매에 기초한 코팅제와는 달리 인체에 무해하며 화재나 폭발의 위험성도 없는 장점을 가지고 있다.One of the proposed methods to solve this disadvantage is to use an aqueous coating agent prepared using water as a solvent or dispersion medium. Unlike coatings based on organic solvents, it is harmless to the human body and there is no risk of fire or explosion. has a

즉, 종이용 코팅액은 수성 용매를 사용하되, 내수도, 내유도, 투습도, 해리도, 코팅성, 안티블로킹성 및 히트 실링(heat sealing)을 동시에 매우 우수하게 만족할 뿐만 아니라 부가적으로 종이 강도 향상 효과까지 나타내면 더욱 좋은데, 현재까지 시중에 판매되는 종이용 코팅액 중에는 이를 만족하는 제품이 없는 실정이다.That is, the coating solution for paper uses an aqueous solvent, but it not only satisfies water resistance, oil resistance, moisture permeability, dissociation degree, coating property, anti-blocking property and heat sealing at the same time, but also improves paper strength. It is even better if it shows an effect, but there is no product that satisfies this among the coating solutions for paper sold on the market so far.

이에, 본 발명자들은 물을 용매 혹은 분산매로 사용한 종이용 수성 코팅 조성물에 관하여 연구하던 중, 제1액(아크릴 에멀젼)에서 아크릴계 모노머들의 최적 함량비, 제1액(아크릴 에멀젼)과 제2액(왁스/실리콘 에멀젼)의 최적 함량비, 제2액에서 왁스 에멀젼과 실리콘 에멀젼의 최적 중량비를 도출하여, 내수도, 내유도, 투습도, 해리도, 코팅성, 안티블로킹성 및 히트 실링(heat sealing)을 모두 매우 우수하게 만족할 뿐만 아니라, 부가적으로 종이 강도 역시 향상되는 효과가 있음을 확인하고, 본 발명을 완성하였다.Therefore, the present inventors were researching on the aqueous coating composition for paper using water as a solvent or dispersion medium, the optimal content ratio of acrylic monomers in the first liquid (acrylic emulsion), the first liquid (acrylic emulsion) and the second liquid ( By deriving the optimum content ratio of wax/silicone emulsion) and the optimum weight ratio of wax emulsion and silicone emulsion in the second liquid, water resistance, oil resistance, moisture permeability, dissociation degree, coating property, anti-blocking property and heat sealing In addition to satisfying all of them very excellently, it was confirmed that there is an effect of additionally improving the paper strength, and the present invention was completed.
