Problems solved by technology

[0003] However, most of the traditional fountain solution contains alcohol, and the alcohol is mainly composed of isopropanol, which is a low-boiling, highly volatile flammable organic solvent, which is harmful to the human body. In addition, alcohol also affects the gloss of the ink. impact, and damage to the rubber roller
What's more, isopropanol emissions can also pollute the environment
Therefore, the use of isopropyl alcohol is unfavorable to the environment, the human body, printing equipment and product quality. Therefore, a kind of alcohol-free fountain solution is urgently needed

Abstract

The invention discloses an alcohol-free fountain solution. The alcohol-free fountain solution is prepared from, 1%-5% of hydroxyethyl cellulose, 0.5%-5% of sodium dihydrogen phosphate, 0.5%-5% of trisodium phosphate, 5%-20% of ethylene glycol, 5%-20% of propylene glycol, 0.1%-3% of polyvinyl chloride dehydrated sorbitan laurate, 0.1%-3% of polyvinyl chloride glyceryl ether, 0.01%-1% of 5-chloro-2-methyl-4-isothiazolin-3-one bactericide, 0.01%-1% of antifoaming agents and 50%-70% of deionized water. A production method of the alcohol-free fountain solution comprises the steps of S1, material preparation; S2, stirring for the first time; S3, stirring for the second time; S4, filtering; and S5, filling. According to the alcohol-free fountain solution, the formula is simple, the production process is simple, and the effect can be well achieved.

Description

technical field [0001] The invention relates to the technical field of fountain solution, in particular to an alcohol-free fountain solution and a production method thereof. Background technique [0002] Fountain solution, also known as wetting solution, sink solution, bucket solution. Fountain solution contains wetting agent, which changes the surface tension of the printing plate surface, and PREMIER FOUNT, which adds wetting control ingredients, can also help reduce the amount of ink while obtaining clear dots and vivid colors. Its pH buffer system can provide a constant and stable pH value (4.5-5.5), and is suitable for all kinds of water quality (the problem of soft and hard water has been solved by a unique method that can make both soft water and hard water reach an intermediate state. Solved by the chemical formula, which makes it easier to control the conductivity), the anti-corrosion composition helps to protect your machine. It is a highly concentrated product a...
