Abstract

The present invention relates to a method of dramatically increasing the water resistance of disposable paper products, and more specifically, to a method of manufacturing novel eco-friendly water-resistant disposable paper products, which makes use of an existing disposable paper product manufacturing facility. In addition, by not employing a polymer coating on the inside, which is an existing method of ensuring water resistance, the method of the present invention can fundamentally prevent substances harmful to the human body, such as environmental hormones, from being eluted due to hot water. The disposable paper products according to the present invention are not at all different from conventional products in terms of shape, and since no polymer is used as water repellent, which cause problems for recycling used disposable paper products, it is possible to recycle the used disposable paper products and there is no risk of chemical substances harmful to the human body being eluted. Thus, the disposable paper products of the present invention can be used for various purposes, and especially, cause no problem in terms of waste disposal.

Description

내수성이 향상된 일회용 종이 제품의 제조 방법 {How to manufacture disposable paper products with improved water resistance}How to manufacture disposable paper products with improved water resistance

본 발명은 건조시 내수성이 대폭 향상된 세라믹 바인더 제조 및 일회용 종이 제품의 표면에 이를 코팅하여 내수성 확보 목적으로 폴리머를 코팅할 필요가 없는 내수성이 대폭 향상되고, 재활용이 가능한 일회용 종이 제품의 제조에 관한 것이다.The present invention relates to the manufacture of a ceramic binder and a water-resistant significantly improved drying resistance and the coating of the surface of the disposable paper products to improve the water resistance without the need to coat the polymer for the purpose of securing water resistance, and to the manufacture of disposable paper products that can be recycled .

일회용 종이 제품은 커피컵, 일회용 도시락통, 일회용 접시 및 식품 용기 등 다양한 목적으로 사용되나, 대부분의 경우 물과 접촉하는 부위의 내수성 확보를 위하여 내부에 폴리머 등과 같은 내수성 화학 물질을 사용한다. 따라서 일회용 종이 제품을 사용할 때마다 사람들은 혹시 모를 인체에 해로운 화학 물질의 용출 가능성에 대하여 불안해하며 특히 사용한 일회용 종이 제품은 이들 코팅된 폴리머로 인하여 재활용이 거의 불가능하다. 땅에 매립할 경우 코팅된 폴리머로 인하여 썩는데 오랜 시일이 필요하고, 소각시 유해 물질의 방출이 우려된다.Disposable paper products are used for various purposes, such as coffee cups, disposable lunch boxes, disposable plates and food containers, but in most cases, water resistant chemicals such as polymers are used to secure water resistance of water contacting areas. Therefore, every time a disposable paper product is used, people are anxious about the possible dissolution of chemicals which may be harmful to the human body. Especially, the disposable paper product used is almost impossible to recycle due to these coated polymers. When landfilled, the coated polymer requires a long seal to rot and concerns about the release of hazardous substances during incineration.

이에 세계적인 커피 프랜차이즈 본부에서는 인체에 무해하고, 사용한 제품의 재활용 또는 매립을 포함한 소각시에도 환경에 부담을 주지 않는 일회용 종이 제품의 개발을 추구하고 있으나, 현 시점까지도 이들 제품의 개발이 성공(여기서 성공이라 함은 합리적인 가격에 제조 및 판매가 가능한 제품의 생산을 의미함)이 되었다는 뉴스는 접하지 못하고 있는 실정이다.The global coffee franchise headquarters is pursuing the development of disposable paper products that are harmless to the human body and do not burden the environment during incineration including recycling or landfilling used products. This means that the production of products that can be manufactured and sold at a reasonable price) is not heard.

이들 일회용 종이 제품에 대한 수요는 지속적으로 증가하고 있으며, 특히 프랜차이즈 점에서 발생하는 일회용 종이 제품의 수거 및 폐기에 상당한 비용을 지불하고 있다. 더구나 몇 년 이내에 일회용 종이 제품뿐만 아니라 일회용 플라스틱 용기도 사용에 대하여 규제를 할 것으로 예상된다. The demand for these disposable paper products continues to increase, and in particular, significant costs are paid for the collection and disposal of disposable paper products that occur at franchises. Moreover, within a few years, disposable plastic containers as well as disposable plastic containers are expected to be regulated.

이러한 관계로 이들 일회용 종이 제품 및 플라스틱 용기를 대체할 수 있는 기술 개발이 시급한 실정이며, 특히 폐기 시에 환경에 부담을 줄이는 것이 대단히 중요한 문제로 대두되었다.In this regard, it is urgent to develop technologies to replace these disposable paper products and plastic containers, and in particular, it is very important to reduce the burden on the environment at the time of disposal.

이와 같은 문제를 해결하기 위한 경제성이 확보된 새로운 기술 개발이 필요하다.To solve these problems, there is a need to develop new technologies with economic feasibility.

본 발명은 건조시에 수분에 강한 무기바인더 및 이 무기바인더를 코팅한 내수성이 확보된 일회용 종이 제품의 제조하는 것이다.The present invention is to manufacture an inorganic binder which is resistant to moisture during drying and a disposable paper product having a water resistance which is coated with the inorganic binder.

본 발명은 코팅시 내수성을 확보할 수 있는 일회용 종이 제품 및 무기 코팅액을 제공한다. 일회용 종이 제품을 다양한 목적으로 사용하기 위하여 내수성 코팅이 필수이며, 또한 코팅시 유해물질이 방출되지 않도록 해야 한다.The present invention provides a disposable paper product and inorganic coating liquid which can ensure water resistance during coating. In order to use disposable paper products for various purposes, a water-resistant coating is necessary, and the coating must be free of harmful substances.

청구항 1에 의하면 종이 제품에 코팅된 내수 코팅면으로부터 유해물질이 녹아나오지 않는다.According to claim 1, no harmful substances are melted from the water-resistant coated surface coated on the paper product.

청구항 2에 의하면 코팅액의 주 성분이 세라믹이므로 뜨거운 물에 접해도 유해 물질이 녹아나오지 않는다.According to claim 2, since the main component of the coating liquid is ceramic, harmful substances do not melt even when contacted with hot water.

청구항 4에 의하면 코팅 방식으로 특별히 어려운 문제는 없으며, 일반적으로 쉽게 적용할 수 있는 관계로 일회용 종이 제품의 단가를 특별히 많이 올리지는 않는다.According to claim 4, there is no particular problem with the coating method, and in general, the unit price of the disposable paper product is not particularly high because it is easily applicable.

청구항 6 및 7에서 세라믹 무기 바인더는 코팅 후 단순한 열풍 건조 또는 전자레인지를 이용한 건조를 하면 되며, 특별히 무기 바인더를 고온에서 열처리를 할 필요가 없으므로 일회용 종이 제품의 단가를 특별히 많이 올리지는 않는다.In claim 6 and 7, the ceramic inorganic binder may be dried by using simple hot air drying or microwave oven after coating, and in particular, the inorganic binder does not need to be heat-treated at a high temperature, and thus does not increase the unit cost of the disposable paper product much.

이상 상술한 바와 같이 세라믹 무기 바인더를 코팅한 일회용 종이 제품은 내수성이 우수하며, 제조 공정이 기존 비닐과 같은 화학물질을 코팅한 일회용 종이 제품의 생산과 특별히 다른 제조 공정을 거치지 않으므로 기존 일회용 종이 제품을 생산하는 공정에서 생산이 가능하며, 생산 단가도 기존 방식에 비하여 크게 차이가 나지 않을 것으로 생각된다. 특히 기존 화학물질이 코팅된 일회용 종이 제품의 폐기시에 발생하는 문제는 없으며, 환경 친화적으로 처리가 가능하다. 따라서 본 발명이 적용된 일회용 종이 제품은 생산 및 폐기에 별다른 환경적인 문제를 야기하지 않으므로, 폐기물 처리에 별다른 애로 사항은 없다.As described above, the disposable paper product coated with the ceramic inorganic binder is excellent in water resistance, and the existing disposable paper product is not manufactured because the manufacturing process does not go through a manufacturing process that is particularly different from the production of the disposable paper product coated with a chemical such as vinyl. Production is possible in the production process, and production costs are unlikely to be significantly different from existing methods. In particular, there is no problem occurring in the disposal of the disposable paper products coated with the existing chemicals, it can be treated environmentally friendly. Therefore, the disposable paper product to which the present invention is applied does not cause any environmental problems in production and disposal, and thus there is no problem in waste disposal.

본 발명에 따른 세라믹 바인더를 이용한 내수성 일회용 종이 제품의 제조 방법은 다음과 같다.The manufacturing method of the water resistant disposable paper product using the ceramic binder which concerns on this invention is as follows.

인체에 무해한 이산화규소(SiO2) 또는 삼산화알루미늄(Al2O3)를 주성분으로 하는 무기질 세라믹 바인더를 적절한 농도로 조정한다. 이때 농도는 적용할 일회용 종이 제품의 목적 및 사용 종이의 특성에 따라 다를 수 있으나, 대체로 이소프로필알콜(IPA) 또는 물을 첨가하여 바인더 농도가 10%내지 90%가 되도록 조절하면 된다. 농도가 너무 낮으면 내수성에 문제가 있을 수 있고, 농도가 너무 높으면 제조 원가가 상승하고, 세라믹 코팅막의 두께가 필요 이상으로 두꺼워질 수 있기 때문이며, 특이한 경우를 제외하고는 대체로 농도가 50%가 적절하다.An inorganic ceramic binder composed mainly of silicon dioxide (SiO 2 ) or aluminum trioxide (Al 2 O 3 ), which is harmless to the human body, is adjusted to an appropriate concentration. At this time, the concentration may vary depending on the purpose of the disposable paper product to be applied and the characteristics of the paper used, but is generally adjusted to the binder concentration is 10% to 90% by adding isopropyl alcohol (IPA) or water. If the concentration is too low, there may be a problem in water resistance. If the concentration is too high, the manufacturing cost may increase, and the thickness of the ceramic coating may be thicker than necessary, and in exceptional cases, the concentration is generally 50%. Do.

이소프로필알콜은 코팅후 건조시에 회수하는 장치를 추가할 경우 거의 100% 회수가 가능하며, 이소프로필알콜은 산업에서 다양하게 사용되고, 70% 농도의 이소프로필알콜은 피부 소독약으로도 사용된다.Isopropyl alcohol can be recovered almost 100% by adding a device to recover the drying after coating, isopropyl alcohol is used in various industries, and isopropyl alcohol of 70% concentration is also used as a skin antiseptic.

기존 일회용 종이 제품의 원료 종이에 상기와 같이 준비된 무기질 세라믹 바인더를 적절한 스프레이 장치를 이용하여 한쪽면에 무기질 세라믹 바인더를 코팅한다. 여기서 코팅이라 함은 단순히 스프레이 장치를 이용하여 분무하는 것을 의미한다. 분무량이 너무 많으면 종이에 다량의 수분 및 무기질 세라믹 바인더가 묻어서 건조시에 시간이 많이 걸리고, 또한 종이의 형태가 변형될 수 있으므로 적절한 양을 도포하는 것이 제품 품질 관리에 중요한 요소이다.The inorganic ceramic binder prepared as described above on the raw paper of the existing disposable paper product is coated with an inorganic ceramic binder on one side using an appropriate spray apparatus. Coating here means simply spraying using a spray device. If the amount of spray is too high, a large amount of moisture and inorganic ceramic binders are applied to the paper, which takes a long time when drying, and the shape of the paper may be deformed, so applying an appropriate amount is an important factor in product quality control.

상기와 같이 무기질 세라믹 바인더가 코팅된 종이를 열풍 건조기 또는 고주파 건조로를 통과시키면 일회용 종이 제품을 만들기 위한 재료가 만들어지며, 이와같이 코팅된 종이를 기존 일회용 종이 제품을 만드는 공정에 그대로 적용시키면 내수성 일회용 종이 제품이 만들어진다.When the paper coated with the inorganic ceramic binder is passed through a hot air dryer or a high frequency drying furnace, a material for making a disposable paper product is made. When the coated paper is applied to a process for making a disposable paper product as it is, a water-resistant disposable paper product is applied. This is made.
