Alcohol-free fountain solution for printing and preparation method thereof

Abstract

The invention discloses an alcohol-free fountain solution for printing and a preparation method thereof. The alcohol-free fountain solution is composed of, by weight, 2-4% of apricot glue, 4-6% of dipropylene glycol methyl ether, 3-5% of sodium metasilicate, 0.5-1% of octadecyl dimethyl benzyl ammonium chloride, 1-3% of cocamidopropyl betaine, 0.5-1% of lauryl dimethyl amine oxide, 1.5-2.5% of lanolin alcohol polyoxyethylene ether, 2-4% of triethanolamine phosphate, 1.5-2.5% of liquid citric acid, 1-2% of zinc nitrate and the rest water. The alcohol-free fountain solution is free of adding of any alcohol, completely free of containing of VOC substances, completely environment friendly and harmless to human body, has the advantages of low surface tension, good wettability and stable chemical performance, is an ideal fountain solution for a high-speed multicolor offset press, can remarkably improve printing effect and quality, is simple in preparation process and low in production cost, and has important economic and social benefit.

Description

technical field [0001] The invention relates to a printing fountain solution and a preparation method thereof, in particular to an alcohol-free fountain solution for printing and a preparation method thereof. Background technique [0002] Fountain solution is an indispensable chemical additive in the printing process of the printing machine. It forms a uniform water film on the blank part of the printing plate to resist the infiltration of the ink on the graphic to the blank part and prevent the plate from being dirty. However, the alcohol component in the currently used fountain solution is mainly isopropanol, which is a low-boiling, highly volatile flammable organic solvent, which is harmful to the human body. The rollers are also damaged. What's more, isopropanol emissions can also pollute the environment. Therefore, the use of isopropanol is harmful to the environment, human body, printing equipment and product quality. It is an inevitable trend to avoid using isopropa...
