Description
이 발명은 내유지 원지 제조시 소정의 고분자 물질을 사용하여 내유제의 침투성이 균일하고, 발수성이 높으며 습윤 강도가 우수한 내유지 원지 및 이를 사용한 내유지에 관한 것이다.The present invention relates to an oil-resistant paper and oil-resistant paper using the same, using a predetermined polymer material in the production of oil-resistant paper, having a uniform permeability of the oil-resistant agent, high water repellency, and excellent wet strength.
내유지란 종이에 내유성을 갖는 약품을 처리하여 기름이 침투하기 어려운 종이를 말한다.Oil-resistant paper refers to paper which is difficult to penetrate oil by treating chemicals having oil resistance on paper.
이의 제조 방법으로서 약품의 처리 방법에 따라 펄프와 약품을 함께 혼합하는 내첨법, 원지를 만들고 원지 위에 내유제를 도포하는 표면처리법으로 통상 실시되고 있다.As a manufacturing method thereof, it is usually carried out by an internal method of mixing pulp and drug together according to a chemical treatment method, and a surface treatment method of making a base paper and applying an oil resistant agent on a base paper.
일반적으로 종이를 제조함에 있어서 잉크나 물의 흡수도를 조절하기 위하여 명반, 로진 사이즈(Rosin size)제, 셀룰로오스 반응성 사이즈제, 자기 정착형 양이온 폴리머 사이즈제와 같은 물질로 사이징한다.Generally, in the manufacture of paper, in order to control the absorbency of ink or water, it is sized with materials such as alum, rosin size agent, cellulose reactive size agent, and self-fixing cationic polymer size agent.
내유지 제조에 있어서는 이들 첨가제들이 내유제와 화학적 반응을 하지 않도록 사이징제의 선택에 주의하여야 한다.In oil-resistant preparations, care must be taken in the selection of sizing agents such that these additives do not chemically react with the oil-resistant agent.
내첨법에 의한 내유지 제조는 내유제를 건량 펄프에 대하여 0.3∼1.0중량%를 제지공정중 펄프(pulper) 또는 헤드 박스(head box) 단계에 투입함으로써 이루어진다. 따라서 내유제와 결합하기 쉬운 명반 또는 로진 사이징제와 같은 산성 첨가제의 사용은 내첨법에 의한 내유지 제조에 바람직하지 않다.Production of oil-resistant oil by the internalization method is achieved by adding 0.3 to 1.0% by weight of the oil-resistant agent to the pulp or head box stage in the papermaking process. Therefore, the use of acidic additives such as alum or rosin sizing agents that are easy to bind with oil-resistant agents is undesirable for the production of oil-resistant oils by the internalization method.
표면 처리법은 상기한 바와 같이 원지위에 내유제를 코팅하는 방법으로서 표면 처리법으로 제조될 수 있는 원지의 사이즈도가 낮고, 습윤강도가 높으며, 내유제의 침투가 균일하여야 하는 특성을 지녀야 하므로, 이러한 특성을 구비하기 위하여서는 표면 처리법에 사용되는 원지는 고가의 화학 펄프만으로 제조되어져야 했다.As described above, the surface treatment method is a method of coating an oil-resistant agent on the base material, and thus, the base paper that can be produced by the surface treatment method has a low size, high wet strength, and uniform penetration of the oil-resistant agent. In order to have the characteristics, the base paper used for the surface treatment method had to be made only of expensive chemical pulp.
따라서 내유지 제조시 이와 같은 문제점들을 해결하기 위하여 내첨법에 의한 사이징에서는 사이징제를 중성 계통의 셀룰로오스 반응성 사이징제를 사용하고, 충전물의 함량을 최소로하여 내유제의 침투를 용이하게 하는 방법들이 제안되었다.Therefore, in order to solve these problems in the production of oil-resistant oils, sizing agents using neutral cellulose-reactive sizing agents have been proposed in the internalization method, and methods for facilitating penetration of oil-resistant agents by minimizing the content of fillers are proposed. It became.
또한 표면 처리법에서는 원지의 지절 현상 및 강도감소를 최소화하기 위하여 우레아 포름 알데하이드 수지, 멜라민 포름 알데하이드 수지, 에폭시화 폴리아미드 수지 등을 내첨하고 내유제와 전분 또는 폴리비닐 알콜을 코팅하는 방법들이 사용되었다.In addition, in the surface treatment method, urea formaldehyde resin, melamine formaldehyde resin, epoxidized polyamide resin, and the like, and coating of oil-resistant agent and starch or polyvinyl alcohol were used in order to minimize the paper phenomena and the decrease in strength.
그러나 이들 방법으로 제조된 내유지 원지들은 원지 위에 내유제를 처리할 때 내유제의 침투가 불륜일하며 습윤강도가 낮아 지절 현상이 많이 발생하는 문제점이 여전히 존재한다.However, the oil-resistant papers produced by these methods still have a problem in that the penetration of the oil-resistant agent is uneven when the oil-resistant agent is treated on the paper and the wet strength is low.
이 발명은, 상기와 같은 문제점들을 해결하기 위하여 안출된 것으로서, 내유제의 침투성이 균일하고, 발수성이 높이며, 습윤강도가 우수한 내유지 원지 조성물 및 이를 이용한 내유지의 제조 방법을 제공하는 것을 목적으로 한다.The present invention has been made to solve the above problems, and an object of the present invention is to provide an oil-resistant paper base composition having a uniform permeability of oil-resistant agent, high water repellency, excellent wet strength and a method for producing oil-resistant oil using the same. do.

[평가방법][Assessment Methods]
1)내유도1) oil resistance
TAPPI Um-557 방법에 의한 KIT 테스트 변형하여 표1의 등급으로 나타내었다.Modified KIT test by TAPPI Um-557 method is shown in the grade of Table 1.
2)내유도 편차2) oil resistance deviation
제조된 내유지의 폭방향으로 10등분하여 1)의 방법으로 내유도를 측정하여 최고값과 최소값의 차이로 하였다.The oil resistance was measured by the method of 1) by dividing into 10 widthwise directions of the produced oil-resistant oil, and it was set as the difference between the highest value and the minimum value.
3)발수도3) water repellency
KS M7057 규격에 의하여 평가하였다.Evaluation was made according to the KS M7057 standard.
4)습윤강도4) wet strength
TAPPI Om-81 규격에 의하여 평가하였다.Evaluation was made according to the TAPPI Om-81 standard.
상기 결과에서 이 발명에 따라 제조된 내유지는 내유도가 9∼13, 내유도 편차가 3이하, 발수도 등급이 최소한 R4 등급이상, 습윤강도가 1.4 이상으로 종래 아크릴 니트릴 공중합체의 사용이 없는 방법에 의하여 제조된 내유지가 갖는 내유도 2∼11, 내유편차 9이상, 발수도 R3 등급이하, 습윤강도 1.1이하에 비하여 내유도 및 발수도가 우수하고 습윤강도가 크며 내유도의 편차가 적음을 알 수 있다.In the above results, the oil-resistant prepared according to the present invention has an oil resistance of 9 to 13, an oil resistance deviation of 3 or less, a water repellency grade of at least R4 grade, and a wet strength of 1.4 or more, without using the conventional acrylonitrile copolymer. Compared with oil resistance 2-11, oil resistance 9 or more, water repellency R3 or less, wet strength 1.1 or less, excellent oil and water repellency, large wet strength and less oil resistance, It can be seen.
즉 이 발명에 따라 제조된 내유지는 내유제의 성분인 불화인산 화합물과의 호화성이 크고 물에 대한 저항성이 큰 아크릴로 니트릴 공중합체를 내유지 원지 중에 첨가함으로써 내유제의 표면 코팅시 내유제가 내유지 원지내로의 침투를 용이하게 하고, 내유제 침투를 균일하게 하여 내유제의 분포가 균일하며, 습윤강도가 개선된 물성을 갖을 수 있게 되었다.In other words, the oil-resistant oil produced according to the present invention is added to the oil-resistant paper by adding an acrylonitrile copolymer having high gelatinization ability and water resistance to the fluorinated phosphate compound which is a component of the oil-resistant oil in the oil-resistant paper. It is easy to penetrate into oil-resistant paper, and the oil-proof agent penetration is uniform, so that the distribution of oil-resistant agent is uniform, and the wet strength can be improved.
