    • 본발명은, 습수액본연의역할을향상시켜환경유해물질인 I.P.A,MeOH, EtOH등의사용량을최소화하거나사용하지않아도우수한인쇄품질및 작업적성이나오도록친환경저알콜인쇄습수액의개발을목적으로하는친환경저알콜인쇄습수액에관한것이다. 친환경저알콜인쇄습수액을이용함으로서, 현재인쇄시사용되는환경유해물질인 I.P.A(이소프로필알콜)을대부분인쇄시 7% ~ 10% I.P.A의사용량을최소화하여사용하고있으나, 개발제품의경우는 I.P.A를 2% 미만사용할수 있는친환경저알콜인쇄수습액을제공하는것에있다. 국내외휘발성유기화학물질의사용량규제에대처할수 있으며거의대부분수입에의존하는습수액을국산화하여수입대체에도기여할수 있을것으로판단된다.이번연구는 Alcohol Type 습수액의장단점을분석하고또한각 원료의특성과조성에대해새로이분석하고친환경원료의도입등으로습수액자체의친환경화를실현하였으며 IPA 사용량감소로인한표면장력관련문제및 판오염관련문제들을개선하였고또한 pH 완충능력을향상할 수있었다.

    • PURPOSE: A fountain solution for offset printing is provided to make isopropyl alcohol not to be used to have a low VOC(Voltaic Organic Compound) figure, thereby preventing the generation of air pollution and a harmful work environment. CONSTITUTION: A fountain solution for offset printing is composed of, in wt%: ethylene glycol 4, 2.8-3.2 of two-butoxyethanol, 5 of gum, 2.4-2.6 of buffer acid, 1.9-2.1 of ammonium nitrate, 0.45-0.55 of surfactant, 13 of propylene glycol, 20 of glycol ether, 48 of water and sodium, 1.9 of sodium hexametaphosphate. The gum includes at least one group selected from the group of Arabian gum, cellulose, carboxymethyl cellulose, guar gum and xanthan gum.
    • 目的:提供胶印用润版液,使异丙醇不能用于低VOC(伏特有机化合物)数字,从而防止空气污染的产生和有害的工作环境。 构成:用于胶印的润版液由以下组成:乙二醇4,2.8-3.2的双丁氧基乙醇,5的胶,2.4-2.6的缓冲酸,1.9-2.1的硝酸铵,0.45-0.55的 表面活性剂,13份丙二醇,20份乙二醇醚,48份水和钠,1.9份六偏磷酸钠。 口香糖包括选自阿拉伯胶,纤维素,羧甲基纤维素,瓜尔胶和黄原胶中的至少一种。
