Description

내유지 및 그의 제조 방법Oil-resistant fat and its manufacturing method

본 발명은 내유지 및 그의 제조 방법에 관한 것으로서, 더욱 상세하게는 내유지 원지에 내유제 침투 향상제를 더욱 첨가하므로서, 내유성 및 습윤강도가 월등히 향상된 내유지를 제조하는 방법에 관한 발명이다.The present invention relates to oil-resistant oils and a method for producing the same, and more particularly, to a method for producing oil-resistant oils with significantly improved oil resistance and wet strength by further adding oil-proof agent penetration enhancer to oil-resistant oil paper.

일반적으로 내유지란 종이에 내유성을 갖는 약품을 처리하여 기름이 침투하기 어렵도록 만든 종이를 말한다. 이와 같은 내유지를 제조하는 방법으로는 크게 내첨법과 표면처리법이 있다. 내첨법은 건량펄프에 대하여 0.3∼1.0중량 %의 내유제를 펄프 또는 헤드박스등에 첨가하여 내유지를 제조하는 방법으로서, 이 때 내유 효과가 상쇄됨을 방지하기 위하여, 통상 사이징 처리시 알람이나 로진사이즈제 등의 산성 사이징 처리는 하지 않는다. 표면 처리법은 쇄목 펄프와 재생 펄프를 사용하지 않고 100% 화학 펄프만을 사용하여, 탈크, 탄산칼슘, 크레이 등의 충전물을 첨가하지 않은 원지위에 내유제를 코팅하여 내유지를 제조하는 방법으로서, 이 때 사이징 처리는 로진 사이즈제 계통의 산성 사이징을 피하고 주로 중성 사이징을 하며, 통상 여기에 사용되는 원지는 사이즈도가 낮고, 습윤 강도가 높으며, 내유제의침투가 용이한 원지여야만 한다.In general, oil-resistant paper refers to a paper made by treating oil-resistant chemicals on paper so that oil is difficult to penetrate. As a method of manufacturing such oil-resistant oil, there are largely an internal additive method and a surface treatment method. The internalization method is a method for producing oil-resistant oil by adding 0.3-1.0% by weight of an oil-resistant agent to a pulp or a headbox, based on dry pulp.In order to prevent the oil-proof effect from being canceled at this time, an alarm or rosin size is usually applied during sizing There is no acid sizing treatment such as agent. The surface treatment method uses 100% chemical pulp without using groundwood pulp and recycled pulp, and manufactures oil-resistant fat by coating oil-resistant on raw paper without adding fillers such as talc, calcium carbonate and crayfish. The sizing treatment avoids acid sizing of the rosin sizing system and is mainly neutral sizing, and the base paper generally used here should be of low size, high wet strength and easy penetration of oil-resistant oil.

일반적으로 종이를 제조함에 있어서는, 잉크 또는 물의 흡수도를 조절하기 위하여 사이징 처리를 한다. 그러나, 내유지를 제조함에 있어서는 알람을 사용하여 로진 사이징한 산성지는 내유제를 침전시키는 역할을 하므로 이들을 이용하여 내유지를 제조할 때에는 킬레이트 에이전트를 사용해야만 한다는 단점이 있어, 이와 같은 로진 사이징한 종이는 내유지 재조에 있어서는 바람직하지 못하다. 또한 충전제를 함유한 종이는 내유제의 침투가 용이하지 못하여 내유지를 제조함에 이써서는 충전제의 함량을 최소로 유지시키고 사이즈도를 최대한으로 낮추어야만 하는 문제점이 있다.In general, in manufacturing paper, a sizing treatment is performed to control the absorbency of ink or water. However, in manufacturing oil-resistant oil, the acidic paper rosin sized using alarm plays a role of precipitation of oil-resistant oil, so when manufacturing oil-resistant oil using these, there is a disadvantage that a chelating agent must be used. Is not desirable for oil-resistant preparations. In addition, the paper containing the filler is not easy to penetrate the oil-resistant in manufacturing the oil-resistant, there is a problem in that the content of the filler to be kept to a minimum and the size should be reduced to the maximum.

종래에는 이와 같은 문제점을 해결하기 위하여 내첨 사이징 처리에는 셀룰로오스 반응성 사이즈제를 이용한 중성 사이징을 주로 실시하고, 충전물 함량을 최소로 하여 내유제의 침투를 용이하게 하는 방법이 채택되어 왔다. 그리고, 표면 처리시에 지절을 방지하기 위하여 요소 포름알데히드 수지, 멜라민 포름알데히드 수지, 에폭시화 폴리아미드 수지 등을 내첨하는 방법이 채택되어 왔다. 그러나 이와 같은 방법 역시 원지위에 내유제 처리를 할 때 내유제의 침투에 한계가 있어 내유성이 높은 내유지를 제조할 수 없다는 문제점이 있다.Conventionally, in order to solve such a problem, the method for facilitating the penetration of the oil-resistant agent is mainly carried out for the neutralizing sizing using the cellulose reactive sizing agent in the internal addition sizing treatment, and the filling content is minimized. And in order to prevent a trouble at the time of surface treatment, the method of incorporating urea formaldehyde resin, a melamine formaldehyde resin, an epoxidized polyamide resin, etc. has been employ | adopted. However, such a method also has a problem in that the oil-resistant oil-resistant oil can not be produced because there is a limit to the penetration of the oil-resistant agent when the oil-resistant treatment on the original site.

본 발명은 상기한 바와 같은 종래 기술의 문제점을 해결하기 위하여 안출된 것으로서, 본 발명의 목적은 표면 처리 방법에 의하여 내유지를 제조할 때, 내유제의 침투를 용이하게 하므로서 습윤강도 및 내유성이 우수한 내유지 및 그의 제조 방법을 제공하는데 있다.The present invention has been made to solve the problems of the prior art as described above, an object of the present invention is to provide excellent wet strength and oil resistance while facilitating the penetration of the oil agent when preparing the oil-resistant fat by the surface treatment method. It is to provide a fat and oil resistance and a manufacturing method thereof.

상기한 바와 같은 본 발명의 목적을 달성하기 위하여 본 발명은, 펄프 슬러리에 사이즈제, 정착제, 보류제 및 습윤지력 증강제 등으로 구성된 내유지용 첨가제를 첨가하여 제조한 내유지 원지에 있어서, 상기한 내유지용 첨가제가 내유제 침투 향상제를 더욱 포함하는 것을 특징으로 하는 내유지 원지 및 그의 제조 방법을 제공한다. 상기한 방법으로 제조된 내유지 원지에 공지의 내유제 코팅액을 코팅한 뒤, 건조, 카렌다링하여 본 발명의 내유지를 제조할 수 있다. 상기한 내유제 침투 향상제로는 아크릴산과 에틸아크릴산 공중합체를 에틸렌글리콜 디그릴사이딜 에테르와 가교 결합시킨 폴리머를 사용하는 것이 바람직하고, 사용하는 내유제 침투 향상제의 첨가양은 전건펄프에 대하여 0.1 중량 % 내지 0.9 중량%로 하는 것이 바람직하다.In order to achieve the object of the present invention as described above, the present invention, in the oil-resistant base paper prepared by adding an additive for oil-resistant fat composed of a size agent, a fixing agent, a retention agent and a wet strength enhancer, etc. An oil-resistant fat paper and a manufacturing method thereof are provided, wherein the oil-resistant fat additive further comprises an oil-resistant penetration enhancer. The oil-resistant fat paper prepared by the above method is coated with a known oil-resistant coating liquid, and then dried and calendered to prepare the oil-resistant fat of the present invention. It is preferable to use the polymer which crosslinked acrylic acid and ethyl acrylic acid copolymer with ethylene glycol diglycidyl ether as said oil-proof agent penetration improving agent, and the addition amount of the oil-proof agent penetration improving agent used is 0.1 weight% with respect to a total dry pulp. It is preferable to set it as 0.9 weight%.

상기한 내유제 침투 향상제를 0.9 중량% 초과하여 첨가할 경우에는, 내유성 및 내유제의 침투성이 향상은 되지만 원지의 발수성이 떨어지는 문제점이 발생하고, 그 양을 0.1 중량% 미만으로 할 경우 내유제의 침투성이 향상되는 효과를 얻을 수 없는 문제점이 있다.When the oil-proof agent penetration enhancer is added in excess of 0.9% by weight, the oil resistance and the oil-proof agent's permeability are improved but the water repellency of the base paper is inferior. When the amount is less than 0.1% by weight, There is a problem that the effect of improving the permeability is not obtained.

상기한 바와 같은 본 발명의 내유지 원지 조성물을 이용하여 내유지를 제조하는 방법의 대표적인 예는 다음과 같다.Representative examples of the method for producing oil-resistant oil using the oil-resistant paper base composition of the present invention as described above are as follows.

이소프로필 알콜 90 중량%에 물 10중량%를 첨가한 이들 알콜과 물을 합한 중량에 대하여 내유제 (ASABI GUARD AG 530)를 5 중량%, 병용제(MINEX SO)를 1중량% 첨가하여 제조한 내유제 코팅액을, 상기한 실시예와 비교예에서 제조한 내유지 원지 위에, 그라비아 인쇄기로 습윤 픽업량이 50 중량%가 되도록 코팅한 뒤 100℃로 건조시키고, 카렌더에서 온도 50℃, 압력 110 ㎏/㎠로 조절하여 카렌다링 하여 내유지를 제조하였다.To 90% by weight of isopropyl alcohol and 10% by weight of water, 5% by weight of the oil-resistant agent (ASABI GUARD AG 530) and 1% by weight of the combined agent (MINEX SO) were added. The oil-resistant coating liquid was coated on the oil-resistant paper prepared in the above-mentioned Examples and Comparative Examples, coated with a gravure printing machine so that the amount of wet pick-up was 50% by weight, and then dried at 100 ° C. The temperature was 50 ° C in the calender and 110 kg / Adjusting to cm 2 calendered to prepare an oil-resistant.

이와 같이 제조한 내유지의 내유도, 발수도, 습윤 강도를 측정하여 그 결과를 표 2에 나타내었다.The oil resistance, water repellency, and wet strength of the oil-resistant fat thus produced were measured, and the results are shown in Table 2.

상기한 표 2에서 발수도는 KS M 7057 규격에 의하여 측정하였고, 습윤강도는 TAPPI om-81 규격에 의하여 측정하였으며, 내유도는 표 3에 나타난 바와 같이 TAPPI um-557에 의한 KIT test 변형 규격을 사용하여 측정하였다.In Table 2, the water repellency was measured according to the KS M 7057 standard, the wet strength was measured by the TAPPI om-81 standard, and the oil resistance was measured by the KIT test modified standard according to the TAPPI um-557, as shown in Table 3.
