Description
본 발명은 불소수지를 함유하는 내유제로 도포된 친환경성 내유지 및 그 제조 방법에 관한 것으로, 보다 자세하게는 특정한 구성의 불소 수지를 함유하는 내유제로 용지의 표면을 코팅함에 의해 통기성이 우수하면서도 발유 및 발수 성능이 개선될 뿐 아니라 용지에 대한 도포력이 양호하여 접힘 면과 끝 부분까지도 우수한 내유 성능을 나타내고, 또한 내유제의 성분이 인체에 전혀 무해한 친환경적인 성분으로 구성하여 환경오염을 방지하는 불소수지를 함유하는 내유제로 도포된 친환경성 내유지 및 그 제조 방법에 관한 것이다.The present invention relates to an environment-friendly oil-resistant oil coated with an oil-containing oil containing a fluorine resin and a method of manufacturing the same, and more particularly, by coating the surface of the paper with an oil-containing oil containing a fluorine resin of a specific configuration, excellent breathability and oil repellent and Not only does the water repellent performance improve, but the coating power to the paper is good, and it shows excellent oil resistance performance on the folded side and the end, and the fluorine resin prevents environmental pollution by constructing an eco-friendly ingredient that is harmless to the human body. It relates to an environmentally friendly oil-resistant oil coated with an oil-containing oil containing and a manufacturing method thereof.
기술의 발달에 부응하여 각종 재질의 식품 등의 포장용 일회용품의 사용이 급격히 늘어나고 있으며, 특히 그 우수한 장점으로 인하여 플라스틱 제품들이 가장 많이 발달되고 또한 널리 쓰이고 있다. 그러나, 상기 플라스틱 제품들은 우수한 장 점들을 가지고 있지만, 이들 장점에 반해 폐기 후 분해가 거의 되지 않아 심각한 환경오염을 유발하고 있어 그 사용에 제한을 받는다는 절대적인 단점이 또한 있는 실정이다. In response to the development of technology, the use of disposable products for packaging such as food of various materials is rapidly increasing, and in particular, due to its excellent advantages, plastic products are most developed and widely used. However, the plastic products have excellent advantages, but these advantages also have an absolute disadvantage that they are hardly decomposed after disposal, causing severe environmental pollution and thus being limited in their use.
따라서, 상기한 문제점을 해결하기 위한 해결 방안으로 일회용품 분야에서 플라스틱의 환경오염 문제를 해결할 수 있는 대체 재료가 제안되고 있다. 대표적인 예로 플라스틱에 생분해성을 부여한 생분해성 플라스틱과 펄프를 주원료로 한 일회용 종이 용기가 대두되고 있는데, 생분해성 플라스틱 제품은 비용이나 실용성 등의 문제점으로 인하여 만족할 만한 수준에 이르고 있지 못하고, 펄프를 이용하는 제품 또한 펄프의 수급에 있어 대기 및 수질 환경오염이 유발되고 원활한 원자재 공급을 위해 훼손되는 산림을 고려한다면 결코 지속적인 방안이 아니다. 따라서, 펄프를 이용하는 종이 제품으로서 두께를 얇게 하면서도 포장용지로서 제 기능을 할 수 있는 것이 하나의 대안으로 되고 있다. 이를 위해서는 포장용지로 사용되는 종이, 특히 프라이드치킨, 프라이드 포테이토나 도넛, 패스트푸드, 쿠키나 초콜릿 등 과자 제품, 버터나 크림 등 기름기 물기가 많은 식품 등을 포장하는 용지에는 기름이나 물기가 배어 찢어지거나 오염을 막기 위하여 내유성 및 내수성을 부여하는 것이 필수적이며, 이러한 내유성을 부가하기 위해 내유제와 같은 물질이 도포된 용지를 내유지라고 지칭한다.Therefore, in order to solve the above problems, alternative materials are proposed that can solve the environmental pollution problem of plastics in the field of disposable products. As a representative example, biodegradable plastics that give biodegradability to plastics and disposable paper containers based on pulp are emerging. Biodegradable plastic products have not reached satisfactory levels due to problems such as cost and practicality. In addition, the supply and demand of pulp is not a sustainable solution, considering the deteriorated forests that cause air and water pollution and the supply of raw materials. Therefore, as a paper product using pulp, being able to function as a wrapping paper while reducing the thickness has become one alternative. To do this, paper used for wrapping paper, especially fried chicken, fried potatoes or donuts, fast foods, cookies or chocolates such as confectionery products, or greasy foods such as butter or cream, may be splattered with oil or water. It is essential to impart oil resistance and water resistance to prevent contamination, and to add such oil resistance, a paper coated with a material such as an oil resistant agent is referred to as oil-resistant paper.
따라서, 상기한 종래의 환경오염을 유발하는 플라스틱의 사용에 따른 문제점을 해결하여 우수한 내유성을 갖는 포장용지를 제공하기 위해 다양한 제안들이 있어 왔는데, 예를 들어 대한민국 특허출원번호 제2004-0054254호의 "배리어 코팅 조 성물"은 "고형물을 포장하는 원지를 제조하기 위하여 코팅하는 베리어코팅 조성물은, 아크릴산부틸(Butylacrylate) 40 ~ 45 % 와, 스틸렌(Stylene) 40 ~ 45 % 와, 아크릴로니트릴(Acrylonitrile) 4 ~ 7 % 와, 메타크릴산(Methacrylic acid) 4 ~ 7 % 와, 나트륨 계면활성제 1 ~ 3 % 와, 암모늄 퍼스포네이트(Ammonium persulfonate) 0.1 ~ 1 % 와, 암모니아수(Ammonia water) 0.9 ~ 2 % 를 중합시킨 중합물 스틸렌-아크릴레이트 코폴리머 에멀젼(Styrene-Acrylate copolymer emulsion) 39.9 ~ 45 % 와; 암모니아수(Ammonia water) 0.1 ~ 5 % 와;물(Water) 50 ~ 60 % 로 이루어진 것을 특징으로 하는 베리어코팅 조성물"을 개시하고 있으며, 대한민국 특허출원 제2006-0083965호는 "에멀젼 타입의 폴리우레탄 55~65중량％, 불소 실리콘 2~5중량％, 연수 15~30중량％, 아크릴레이트 10~20중량％의 조성을 가진 것을 특징으로 하는 코팅조성액"를 개시하고 있다.Therefore, various proposals have been made to solve the problems caused by the use of plastics causing environmental pollution, and to provide a packaging paper having excellent oil resistance. For example, the "Barrier" of Korean Patent Application No. 2004-0054254 "Coating composition" is "barrier coating composition for coating to prepare the base paper for packaging the solid, butyl acrylate (Butylacrylate) 40 ~ 45%, Styrene (Stylene) 40 ~ 45%, Acrylonitrile 4 ~ 7%, methacrylic acid 4 ~ 7%,
그러나, 상기한 발명들의 코팅 조성액으로 도포된 용지의 내유성이 만족할 만한 정도를 나타내지 못할 뿐 아니라, 상기 종래의 코팅 조성액들은 그 조성분으로 아크릴레이트를 포함하여 통기성이 나빠 식품을 포장하였을 때 포장된 식품을 신선하게 보관할 수 없다는 단점이 있었다. 더욱이, 종래의 포장용지의 내유성 코팅액은 다양한 각종 구성을 포함하는데, 이들 물질들이 식품 포장시 환경 호르몬 발생등에 따라 인체에 유해할 수 있을 뿐 아니라 폐기시 자연환경을 오염시킬 우려가 있는 물질들이 사용되고 있어 인간 및 환경에 바람직하지 않다는 문제점 또한 제기되고 있는 실정이었다.However, not only the oil resistance of the paper coated with the coating composition of the above inventions is satisfactory, but the conventional coating compositions contain acrylate as the composition and thus have poor breathability. There was a disadvantage that it can not be kept fresh. In addition, the oil-resistant coating liquid of the conventional packaging paper includes a variety of configurations, these materials are not only harmful to the human body due to the production of environmental hormones in food packaging, but also used materials that may contaminate the natural environment when disposed of Problems that are undesirable for humans and the environment have also been raised.
따라서, 본 발명의 목적은 포장용기에 있어 상기한 종래의 문제점을 해결하기 위한 것으로, 종이에 우수한 내유성과 통기성을 제공하여 식품 등의 포장에 유용하게 이용될 수 있으면서도 인체에 유해하지 않고 폐기시 환경오염을 유발하지 않는 불소수지를 함유하는 내유제로 도포된 친환경성 내유지를 제공하기 위한 것이다. Accordingly, an object of the present invention is to solve the above-mentioned problems in a packaging container, and provides excellent oil resistance and air permeability to paper, and can be usefully used for packaging such as food, while not being harmful to a human body and being disposed of in an environment when disposed. It is to provide an environment-friendly oil-resistant oil coated with an oil-resistant containing a fluorine resin does not cause contamination.
본 발명의 다른 목적은 상기한 우수한 특성을 갖는 불소수지를 함유하는 내유제로 도포된 친환경성 내유지의 용이한 제조방법을 제공하기 위한 것이다. Another object of the present invention is to provide an easy manufacturing method of environmentally friendly oil-resistant oil coated with an oil-resistant agent containing a fluorine resin having the above excellent characteristics.
또한, 상기한 명확한 목적 이외에 이러한 목적 및 본 명세서의 전반적인 기술로부터 이 분야의 통상인에 의해 용이하게 도출될 수 있는 다른 목적을 달성함을 그 목적으로 할 수 있다.In addition, it may be aimed at achieving other objects which can be easily derived by those skilled in the art from these and other general descriptions of the present specification.

이하, 본 발명을 첨부도면을 참고로 바람직한 일 실시형태에 의해 보다 자세하게 설명한다.Hereinafter, with reference to the accompanying drawings, the present invention will be described in more detail by a preferred embodiment.
본 발명의 바람직한 실시형태에 따라, 종이 재질의 포장 용지 표면에 내유성을 부여하기 위해 사용되는 내유제는 일본의 아사히 글라스 주식회사에서 제조되어 시판되고 있는 상품명 "AG-E060"의 불소수지 수용액, PVA(polyvinyl alcohol), 에 탄올 및 물을 적절한 비율로 혼합하여 사용하였다. 상기 상품명 "AG-E060"의 불소수지 수용액은 불소함유중합체, 초산 및 물로 이루어진 혼합물이다.According to a preferred embodiment of the present invention, the oil-resistant agent used for imparting oil resistance to the surface of paper packaging paper is PVA (aqueous solution of fluororesin under the trade name "AG-E060" manufactured by Asahi Glass Co., Ltd., Japan). polyvinyl alcohol), ethanol and water were mixed and used in an appropriate ratio. The aqueous solution of fluororesin under the trade name "AG-E060" is a mixture consisting of a fluorine-containing polymer, acetic acid and water.
본 발명의 다른 실시형태에 따르면, 상기 내유제의 각 구성성분의 혼합비율은 상기 불소수지 수용액 AG-E060; 5 내지 10중량부, 10% PVA; 30 내지 50 중량부, 에탄올; 20 내지 40중량부 그리고 물; 20 내지 30중량부의 비율로 되도록 한다. According to another embodiment of the present invention, the mixing ratio of each component of the oil-resistant agent is the fluororesin aqueous solution AG-E060; 5 to 10 parts by weight, 10% PVA; 30 to 50 parts by weight of ethanol; 20 to 40 parts by weight and water; The ratio is 20 to 30 parts by weight.
상기 불소수지 혼합물이 5중량부 이하이면, 내유성능이 현저하게 저하하여 바람직하지 않고, 반대로 10중량부 이상에서는 특성의 향상에 비하여 제조원가가 상승하여 바람직하지 않다. 또한, 상기 10% PVA 및 상기 에탄올의 함량이 상기 하한 중량부 이하이면 도포 상태가 열악하여 코팅이 벗겨질 우려가 있으며, 반대로 상한 중량부 이상으로 되면 내열성이 열악해지는 단점이 있어 바람직하지 않다. If the fluororesin mixture is 5 parts by weight or less, the oil resistance performance is remarkably lowered, which is not preferable. In addition, when the content of the 10% PVA and the ethanol is less than the lower limit by weight, the coating state is poor and there is a risk that the coating may be peeled off.
한편, 물의 함량이 20중량부 미만에서는 도막상태가 균일하게 되지 않고 30중량부 이상에서는 건조시간이 증가하여 코팅이 불완전하게 되어 바람직하지 않다.On the other hand, when the content of water is less than 20 parts by weight, the coating state is not uniform, and at 30 parts by weight or more, the drying time is increased, resulting in incomplete coating.
다음으로, 상기 본 발명에 따라 제조된 코팅액을 그라비아 코팅 장치를 사용하여 종이의 일면에 도포하는 방법을 설명한다.Next, a method of applying the coating solution prepared according to the present invention to one surface of the paper using a gravure coating device will be described.
도 1은 마이크로 그라비아 코팅장치를 사용하여 포장용지에 내유제를 코팅하는 상태를 개략적으로 나타내는 개략 측면도이다.Figure 1 is a schematic side view schematically showing a state in which the oil-resistant coating on the packaging using a micro gravure coating device.
먼저, 불소수지 수용액(상품명; AG-E060), 10% PVA(polyvinyl alcohol), 에탄올 및 물을 적절한 비율로 혼합하여 제조한 내유제를 상기 그라비아 코팅장치의 코팅액 조(1)에 사입한다. 이때, 그라비아 롤(4)의 하단 약 1/3 정도가 잠기는 정 도로 사입될 수 있게 오버플로우 라인을 조절하고 과잉의 코팅액은 오버플로우 조(5)로 오버플로우되고, 그런 다음 통상적인 펌프(F)에 의해 코팅액 조(1)로 공급되어 코팅액이 순환된다. 그라비아 롤(4)과 백 롤(2)의 회전에 의해 이들 롤 사이에서 이동하는 용지(3)에 내유제의 코팅액 도포된다. First, an oil-resistant agent prepared by mixing an aqueous fluorine resin solution (trade name; AG-E060), 10% PVA (polyvinyl alcohol), ethanol and water in an appropriate ratio is injected into the
본 발명의 바람직한 실시형태에 따르면, 상기 내유제 코팅량은 일 면 코팅인경우는 14g/㎡ 이상, 바람직하기로는 16g/㎡ 이상의 양으로 코팅되도록 한다. 만일 14g/㎡ 이하로 되면 내유성능이 떨어져 바람직하지 않다. 또한, 20g/㎡를 넘으면 제조비용이 증가하여 바람직하지 않다.According to a preferred embodiment of the present invention, the oil-resistant coating amount is to be coated in an amount of 14g / ㎡ or more, preferably 16g / ㎡ or more in the case of one side coating. If it is 14 g / m 2 or less, the oil resistance is poor, which is not preferable. Moreover, when it exceeds 20 g / m <2>, manufacturing cost increases and it is unpreferable.

또한, 상기와 같이 그라비아 인쇄 방식에 의한 동판 롤을 이용한 코팅 가공 후 약 100℃ 이상에서 건조한다.In addition, after the coating process using a copper plate roll by the gravure printing method as described above is dried at about 100 ℃ or more.
이렇게 제조된 내유제가 도막된 본 발명의 친환경성 내유지는 내열성이 우수한데, 특히 전자레인지 사용시에는 250℃까지 사용 가능하다.The environmentally friendly oil-resistant paper of the present invention having the oil-resistant coating prepared therein is excellent in heat resistance, and in particular, when using a microwave oven, it can be used up to 250 ° C.
또한, 본 발명에 따른 친환경성 불소계 내유지는 통기성이 우수하여 식품포장용도로 사용시 뛰어난 특성을 가진다.In addition, the environmentally friendly fluorine-based oil and fat according to the present invention is excellent in breathability and has excellent characteristics when used for food packaging.
상기와 같이 구성되는 본 발명의 내유지는 본래 용지의 외관 통기성이 상실하지 않게 하면서도 뛰어난 내유성 및 내수성을 용지에 부여하고, 이렇게 제조된 본 발명의 친환경성 내유지는 과자류, 유제품 부식 및 냉동식품 패스트푸드 등 유지류를 포함된 모든 식품 제품의 포장용도에 적합하다.The oil-resistant paper of the present invention configured as described above imparts excellent oil resistance and water resistance to the paper while not losing the appearance breathability of the original paper, and the eco-friendly oil-resistant paper of the present invention thus prepared is confectionary, dairy products corrosion and frozen food fasteners. It is suitable for the packing of all food products including oils and foods.
특히, 본 발명에 따라 특정한 불소수지 수용액을 함유하는 불소계 내유제로 가공한 내유지는 다른 형태의 내유지에 비해서 많은 특유의 장점이 있어 폭넓은 지지를 얻고 있는데, 예를 들어 본 발명에 따른 불소계 내유지는 기름이나 물이 전혀 배지 들지 않을 정도로 내유 및 내수성이 탁월하고, 또한 용지를 접었을 경우 접은 부분이나 또한 용지의 끝 부분으로도 기름이나 물이 배지 않고, 본 발명에 따라 코팅된 내유지는 내구성 또한 우수하여 장시간의 시간이 경과한 후에도 내유 및 내수성능을 유지한다. 또한, 내열성이 우수하여 고온이나 가열 중에도 기름이나 물이 배지 않아 전자레인지 가열에도 사용이 가능하다.In particular, oil-resistant oils processed with a fluorine-based oil-containing oil containing a specific aqueous solution of fluorine resins according to the present invention has a number of unique advantages over other types of oil-resistant oils, and has gained wide support. The oil and fat is excellent in oil and water resistance so that no oil or water is discharged at all, and when the paper is folded, oil or water is not discharged to the folded portion or the end of the paper, and the oil-resistant coating coated according to the present invention is durable. It is also excellent and maintains oil and water resistance even after a long time. In addition, it is excellent in heat resistance, so oil and water do not discharge even at high temperatures or heating, and thus it can be used for microwave heating.
상기 본 발명에 따라 친환경성 불소계 내유제로 가공한 내유지는 그 내부까지 내유제가 침투하여 가공이 되므로 용지의 끊어진 곳과 접어 금(선)이 형성된 곳에도 내유성이 유지된다. 이에 반해 종래의 방법에 따라 불소계 내유제가 아닌 아크릴 코팅이나 라미네이트 용지의 경우는 그 표면만 내유성이 유지되어 끊어진 곳이나 접은 금은 내유성이 없어 사용에 불편을 초래한다. Oil-resistant oil processed by the environmentally friendly fluorine-based oil according to the present invention is oil-resistant to penetrate the inside of the oil is processed because the oil is maintained even in the place where the crack (fold) is formed. On the other hand, in the case of acrylic coating or laminated paper which is not a fluorine-based oil according to the conventional method, oil resistance is maintained only on the surface thereof, and broken or folded gold does not have oil resistance, resulting in inconvenience in use.
특히, 본 발명에 따라 불소수지 수용액을 함유하는 내유제는 가솔린, 알코올, 기름, 물 뿐 아니라 실리콘, 나이론, 셀룰로스에 비하여 월등히 낮은 표면장력을 지니므로 내유특성이 특히 우수하다.In particular, the oil-resistant agent containing an aqueous solution of the fluorine resin according to the present invention has a particularly low surface tension compared to gasoline, alcohol, oil, water, as well as silicon, nylon, cellulose, so the oil resistance is particularly excellent.
또한, 상기와 같이 우수한 내유 및 내수성을 용지에 부여하면서도, 본 발명의 내유 가공지는 원래 용지의 장점을 그대로 유지한다. 따라서, 본 발명에 따른 내유지는 사용된 용지의 외관 부드러움과 통기성을 그대로 유지하면서, 기름기를 차단하고 증기는 통하게 한다. 또한, 이와 더불어 봉지에 충전성을 유지한다.Further, while imparting excellent oil and water resistance to the paper as described above, the oil-resistant processed paper of the present invention retains the advantages of the original paper. Thus, the oil-resistant paper according to the present invention keeps the smoothness and breathability of the used paper intact, while blocking the oil and allowing steam to pass through. In addition, the filling property is maintained in the bag.
이와 같이 본 발명에 따른 불소수지 수용액을 함유한 내유제로 처리된 내유지는 통기성을 양호하게 하여, 이들 내유지로 포장된 식품은 갓 만들어낸 상태를 유지하게 한다. 따라서, 종래의 아크릴코팅 라미네이트 등의 내유지 봉투가 통기성이 불량하여 내용물인 식품이 서로 엉겨붙어 신선함을 저해하는 문제점도 해결할 수 있는 것이다. In this way, the oil-resistant oil treated with the oil-resistant agent containing the aqueous solution of fluorine resin according to the present invention improves breathability, so that the food packaged with these oil-resistant oils is kept fresh. Therefore, it is also possible to solve the problem that the oil-resistant bags such as acrylic coating laminates are poor in breathability and the foods as contents are entangled with each other to inhibit freshness.
상기한 바와 같이 본 발명의 내유제는 불소수지 수용액, PVA(polyvinyl alcohol), 에탄올 및 물로 구성되어 종래의 석유계 원료를 전혀 사용하지 않아 친환경적이며, 이는 FDA 및 BFR이라고 하는 세계 기준에 적합한 정도의 친환경성 제품이다.As described above, the oil-resistant agent of the present invention is composed of a fluorine resin solution, PVA (polyvinyl alcohol), ethanol, and water, which is eco-friendly because it does not use any conventional petroleum-based raw materials, which is suitable for the global standards such as FDA and BFR. It is an eco-friendly product.
