The Effect of Offset Ink Formulation on Deinking of Old Newspaper

초록

본 논문은 옵셋 잉크가 국내 신문고지의 탈묵에 미치는 영향을 조사하기 위해 국내신문 옵셋잉크의 조성분과, 그들 잉크로 옵셋 인쇄된 시료를 10, 30, 90, 180일 동안 열화시킨 후, 이들의 탈묵성을 비교하였다. 인쇄잉크의 조성분을 다르게 하여 인쇄한 시료는 열화기간이 증가될 수록 수율과 백색도가 감소되었다. 특히 아마인유의 첨가량이 많은 시료의 경우, 열화기간에 따라 많은 수율의 감소와 백색도의 저하를 가져왔다. 따라서 아마인유의 첨가량은 탈묵에 결정적인 역할을 한다는 결론을 얻었다. 또한 로진변성페놀수지와 길소나이트가 포함된 시료는 열화과정을 통해 상대적으로 백색도의 감소가 있었다. 강도 측면에서 볼 경우, 열화기간에 따라 대체로 인장지수와 파열지수는 감소하였고, 인열지수는 증가했 다. 그러나 아마인유만을 비이클 성분으로 사용한 시료의 경우 다른 시료에 비해 모든 강도가 낮았는데, 이것은 잉크와 섬유간의 강한 가교결합이 형성되어 초지 시 해리가 어렵기 때문이다.

In this paper, to investigate the effect of the offset ink formulation on deinking of Korean old newspaper, the samples printed with five different types of offset ink were aged naturally for 10, 30, 90, 180 days, and then yield, brightness, fiber length, physical properties(tensile, tear, burst index) were evaluated according to aging time. As the aging time increased, the yield and brightness of respective samples decreased. Particially, as the addition amounts of linseed oil increased, those of samples decreased. Therefore, linseed oil is thought to reduce the deinkability of ink. Also, containing rosin-modified phenolic resin and gilsonite seem to reduce brightness of samples according aging time. In physical properties, tensile index and burst index were roughly decreased, but tear index was increased according to aging time. However, the three indexes of the sample containing only linseed oil as the vehicle component were considerably reduced in comparison with those of other samples, as once crosslinked a strong bond between the ink and fibers was produced and made it difficult to defibrate in producing sheets.
