Fountain solution and preparation method thereof

Abstract

The invention discloses a fountain solution which comprises the following components in parts by weight: 2-6 parts of fatty alcohol-polyoxyethylene ether, 1-5 parts of alkyl glucoside, 10-20 parts of Arabic gum, 8-10 parts of citric acid, 3-10 parts of sodium gluconate, 5-24 parts of sulfonated phthalein glucosamine, 9-10 parts of phosphoric acid, 1-8 parts of disodium hydrogen phosphate, 0.01-0.1 part of anticorrosive fungicide, 0.1-2 parts of defoaming agent, 1-5 parts of antioxidant and 10-15 parts of water. The invention also discloses a preparation method of the fountain solution. The preparation method comprises the following steps: weighing the fatty alcohol-polyoxyethylene ether, the alkyl glucoside, the Arabic gum, the citric acid, the sodium gluconate, the sulfonated phthalein glucosamine, the phosphoric acid, the disodium hydrogen phosphate, the anticorrosive fungicide, the defoaming agent, the antioxidant and the water according to certain proportion; dissolving solid raw materials into solution; diluting liquid with water; then respectively feeding the raw materials into a reaction kettle and stirring for 30-45 minutes to obtain the fountain solution. The fountain solution disclosed by the invention has no alcohol and isopropanol, and is convenient to use; the water is only added into the fountain solution to obtain 1-10 percent solution. The fountain solution also has the advantages of low possibilities of hardening and oxidizing.

Description

technical field [0001] The invention relates to a printing fountain solution, in particular to a fountain solution and a preparation method thereof. Background technique [0002] With the continuous development of printing technology, this ancient industry has also transformed from a technology that blindly pursues efficiency to an industry that focuses on sustainable development and lower production costs. However, the dampening solution currently on the market needs to consume a large amount of alcohol or isopropanol or other organic solvents. The tension of the liquid surface is reduced by alcohol and isopropanol, so that the water becomes more "wet" to facilitate its affinity on the printing plate. The water part spreads; while increasing the viscosity of the dampening solution, the alcohol can also sterilize the dampening solution. But alcohol and isopropanol are volatile, and 40% of the added alcohol will evaporate in the air. Alcohol is a very expensive additive. A ...
