Abstract

The invention discloses an alcohol-free printing fountain solution and a preparation method of the alcohol-free printing fountain solution. The alcohol-free printing fountain solution comprises, by weight, 10-15% of propylene glycol monomethyl ether, 2-4% of ethylene glycol, 4-8% of a citric acid, 0.5-1.5% of sodium hydroxide, 15-25% of glycerinum, 0.1-0.3% of sodium carboxymethyl cellulose, 0.05-0.1% of lauroyl diethanol amine, 0.4-0.6% of liquid tea saponin, 0.3-0.6% of dodecyl dimethyl benzyl ammonium chloride, 0.5-1% of dodecyl glucoside, 0.05-0.1% of 2-ethyl hexanol and 50-55% of water. The alcohol-free printing fountain solution does not contain isopropyl alcohol and is low in toxicity, safe, environmentally friendly, good in printing effect and low in cost, thereby having huge economic benefit 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 printing fountain solution and a preparation method thereof. Background technique [0002] At present, alcohol fountain solution is commonly used on offset printing machines, and isopropanol is one of the main additives of fountain solution. Compared with the traditional water dampening system, alcohol dampening solution can greatly reduce the amount of water, and avoid paper deformation and ink excessive emulsification caused by excessive water, thereby greatly improving the printing effect. However, during the use of alcohol fountain solution, isopropanol is easy to volatilize and produce toxic alcohol vapor, which will pollute the environment and cause harm to human health. Nowadays, printing factories all over the world are trying to create environmentally friendly printing and reduce printing costs, replacing isopropyl alcohol ...
