Embodiment 1

[0041] Aluminum-zirconium coupling agent can be obtained according to the following methods:

[0042] A. Dissolve 15 parts of glyoxal and 10 parts of diethanolamine in 90 parts of water in parts by weight, heat to 60°C, react for 60 minutes and cool to room temperature, then add 30 parts of absolute ethanol to precipitate white crystals, Dry in an oven at 50°C to obtain intermediate product A;

[0043] B. Stir 7 parts of basic aluminum chloride and 10 parts of water in a three-necked flask with a stirring and reflux device in parts by weight until basic aluminum chloride is completely dissolved, and drop 1 1 part of hydrochloric acid with a concentration of 36%, then add 15 parts of methanol, add 1 part of 1,2-propanediol after heating to reflux, react for 50 minutes, distill methanol at 60°C, and then dry it in an oven at 100°C to obtain intermediate product B;

[0044]C. Mix 1.1 parts by weight of zirconium oxychloride, 10 parts of 1,2-propanediol and 2.5 parts of intermed...

Abstract

The invention relates to a new application of an aluminum-zirconium coupling agent, in particular to the application of the aluminum-zirconium coupling agent as a quick-drying additive for printing products in fountain solutions of water offset printing machines. During application, 0.5-2.0% by weight of aluminum-zirconium coupling agent is added to the fountain solution of water offset printing machine. Or add 1.5% by weight aluminum-zirconium coupling agent and 1.0% cobalt sulfate to the fountain solution of the water offset printing machine. The present invention has the advantages that: the use of aluminum-zirconium coupling agent as the dampening solution additive for water offset printing machines to make printed products dry quickly can properly reduce the amount of desiccant used in inks, facilitate machine printing, and shorten the production cycle of products and improve It improves the water resistance of the paper and the binding fastness of the paper and the ink, enhances the physical and chemical resistance of the printed matter, and is especially beneficial to improve the machine washing resistance of the banknote printing products.

Description

technical field [0001] The invention relates to a new application of an aluminum-zirconium coupling agent, in particular to the application of the aluminum-zirconium coupling agent as a quick-drying additive for printing products in fountain solutions of water offset printing machines. Background technique [0002] Because the water offset printing plate uses the technology of oil-water separation, the pattern area is inked, and the non-pattern area is filled with water fountain solution. Due to the large amount of fountain solution used, this requires an increase in the amount of ink desiccant. Water offset printing The content of desiccant in machine ink is generally increased to 1.5% to 3%, and dry offset printing ink is generally around 0.5%, otherwise the drying cycle of printed products is too long, and the next step of printing cannot be performed. However, the increase in the amount of ink desiccant will cause ink skinning problems to the ink fountain, rubber roller ...
