Abstract

The invention relates to the technical field of lithographic printing, and discloses a zero-VOC offset printing alcohol-free fountain solution. The solution comprises the following components in parts by weight: 2-8 parts of aromatic sodium sulfonate, 1-6 parts of citric acid, 1-5 parts of ammonium nitrate, 1-5 parts of sodium gluconate, 0.1-0.6 part of branched sodium alkyl sulfate, 0.5-4 parts of modified gum arabic, 2-8 parts of lauryl alcohol polyoxyethylene ether, 0.1-0.2 part of 2,4,7,9-tetramethyl-5-decyne-4,7-diol, 0.05-0.2 part of benzotriazole, 0.02-0.15 part of an anti-corrosion and bactericidal agent, 2-4 parts of a compound functional agent and 60-70 parts of water.The zero-VOC offset printing alcohol-free fountain solution has the beneficial effects that excellent cleaning and wetting effects are realized, volatile matter can be prevented from being generated during use, the zero-VOC offset printing alcohol-free fountain solution is environmentally friendly, the concentration of the zero-VOC offset printing alcohol-free fountain solution is stable in the working process, the replenishing frequency and the replenishing quantity of the fountain solution are greatly reduced, and the labor cost and the printing cost are reduced.

Description

technical field [0001] The invention relates to the technical field of lithographic printing, in particular to an alcohol-free fountain solution for zero-VOC offset printing. Background technique [0002] Printing is identified as a high-pollution industry. In order to reduce the volatilization of organic compounds, alcohol-free dampening solutions must be used for green printing. At present, almost all so-called alcohol-free fountain solutions in the industry use organic solvents such as alcohol ethers to replace alcohols. In fact, some alcohol ethers are more volatile or volatile than alcohol or isopropanol. The original purpose of removing alcohol or isopropanol has not been achieved. Generally, the volatility of alcohol ether solvents is lower than that of ethanol or isopropanol, so the amount added to the fountain solution can be reduced, but it cannot be free of organic matter volatilization, so it also causes greater pollution to the air.
