Problems solved by technology

[0003] There are some alcohol-free dampening solutions on the market, but the technology is immature. For example, the amount and alcohol dampening changes greatly, and it is difficult for operators to control; the stability is not strong, and the frequency of replacing dampening solutions and cleaning water buckets is too high. , increased auxiliary time, etc.

Abstract

The invention discloses an alcohol-free fountain solution and a preparation method thereof. The alcohol-free fountain solution is prepared by emulsifying a mixture formed by polyethylene glycol, glycerol, potassium oxalate, natural bone glue, oleic acid diethanolamide, coconut oil fatty acid diethanolamide, alkanolamide, sodium benzoate, fatty alcohol polyoxyethylene ether sodium sulfate, polyglycol ether, sodium oxalate and water at the temperature of 30-55 DEG C. By using the alcohol-free fountain solution, the aims of realizing safety and environmental friendliness, saving energy and reducing emission can be fulfilled, and a printing operator can be protected from chronic poisoning of alcohol or isopropanol; the original quality of the alcohol-free fountain solution is kept on the aspect of the quality of printed matters, and meanwhile the using amount can be controlled conveniently by operating personnel.

Description

technical field [0001] The invention belongs to the technical field of lithographic printing fountain solution, and in particular relates to an alcohol-free fountain solution and a preparation method thereof. Background technique [0002] Lithographic printing is the current mainstream technology, which uses the principle of "oil and water are immiscible" to carry out printing, so fountain solution is an important printing material. Alcohol fountain solution has been used in lithography for many years. Adding alcohol (or isopropanol) to the fountain solution reduces the surface tension, which not only improves the dampening speed, but also improves the quality of printed products. However, there are also many problems in alcohol dampening, such as because alcohol (or isopropanol) volatilizes quickly and the printing machine adds a cooling device, which makes the machine structure complicated and the manufacturing cost increased; because alcohol (or isopropanol) has a low fla...
