Non-phosphorus fountain solution and preparation method thereof

Abstract

The invention discloses a non-phosphorus fountain solution which is characterized by comprising, by weight, 2-6 parts of 2-hydroxyethyl-beta-cyclodextrin, 1-4 parts of cetearyl glucoside, 1-4 parts of glycerol trioleate, 1-2 parts of terpineol, 1-3 parts of menthone, 0.5-1 part of tartaric acid, 1-3 parts of imidazolidinyl urea, 1-3 parts of sodium lauroamphoacetate, 1-2 parts of sodium xylene sulfonate, 0.5-1 part of benzalkonium chloride, 0.2-1 part of span 60, 5-10 parts of addition agents and 30-50 parts of water. The fountain solution contains no phosphorus, can effectively avoid the adverse effect of phosphorus containing materials on a device, is favorable for device maintenance and reduces cost; deterioration of water quality caused by phosphorus containing emissions is avoided, and the environmental protection requirements are met.

Description

technical field

[0001] The invention relates to a printing fountain solution, in particular to a non-phosphorus fountain solution and a preparation method thereof. Background technique

[0002] Fountain solution is an indispensable chemical additive in the printing process of color printing machines. It forms a uniform water film on the blank part of the printing plate to resist the infiltration of ink on the graphic and text to the blank part and prevent dirty plates. Fountain solution is composed of various components, which can not only generate inorganic salts stably, continuously replenish the worn hydrophilic layer on the blank part of the plate, but also clean the oil on the plate and reduce the temperature of the plate, so that the image and text on the printing plate The ink and the water in the blank part remain relatively balanced and stable to achieve the expected printing effect. The phosphorus contained in the traditional fountain solution will lead to the det...
