A kind of phosphorus-free fountain solution and preparation method thereof

Abstract

The invention discloses a phosphorus-free fountain solution, which is characterized in that it is composed of the following raw materials in parts by weight: hydroxyethyl-β-cyclodextrin 2-6, cetearyl glucoside 1-4, triglyceride Oleate 1‑4, Terpineol 1‑2, Menthone 1‑3, Tartaric Acid 0.5‑1, Imidazolidinyl Urea 1‑3, Sodium Lauryl Amphoacetate 1‑3, Sodium Xylene Sulfonate 1‑2 , benzalkonium chloride 0.5‑1, Span 60 0.2‑1, additives 5‑10, water 30‑50. The raw material of the dampening solution of the present invention does not contain phosphorus, which can effectively avoid adverse effects of phosphorus-containing substances on equipment, is beneficial to equipment maintenance, and reduces costs; at the same time, water quality deterioration caused by phosphorus-containing discharges is avoided, meeting the requirements of environmental protection.

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...

Problems solved by technology

The phosphorus contained in the traditional fountain solution will lead to the deterioration of the metal in the key parts of the equipment. At the same time, the discharge of phosphorus-containing sewage into the water body will cause eutrophication of the water body and cause the deterioration of water quality, thus threatening the natural environment.
