Problems solved by technology

[0003] The binder in the ink plays the role of dispersing the colorant and spreading the auxiliary material, and there are two kinds of solvent-based adhesives and water-based adhesives, but the solvent-based adhesive is the main reagent because the water-based adhesive has a large surface tension. , low solid content, slow drying speed, insufficient bonding strength, etc. have not been well resolved, and solvent-based adhesives are an environmentally friendly coating resin, environmentally friendly and non-toxic, and have excellent comprehensive properties of coating films. It has a good application prospect in decoration and other fields. Among them, modified alcohol-soluble polyacrylate is the main solvent-based adhesive. Its characteristic is that the temperature of the substrate must be higher than 3°C. When the temperature of the substrate is lower than 5°C, the paint film will not cure. , but the modified alcohol-soluble polyacrylate contains a large number of hydrophilic groups, its adhesion and water resistance are relatively poor, and frequent touches can easily cause ink to fall off

Abstract

The invention discloses a method for utilizing acetylacetone titanium in printing ink and paint. According to the method, acetylacetone titanium is effectively added into a modified alcohol solubility polyacrylic ester solution drop by drop, so that a stable polymer is formed. The method has the advantages that the adhesive force and waterproof property of the paint are improved, the possibility of a printing ink peeling phenomenon is lowered, and the drying time is effectively shortened.

Description

technical field [0001] The invention relates to a method for using titanium acetylacetonate in ink and paint. Background technique [0002] Ink is a common material in coatings and an important material for printing. It mainly prints ink on some outer packaging by printing, and ink mainly includes linking materials, pigments, fillers, additives and solvents. It is widely used in outer packaging, books and magazines, exterior walls, daily necessities and other products. With the development of science and social needs, different inks represent different characteristics. [0003] The binder in the ink plays the role of dispersing the colorant and spreading the auxiliary material, and there are two kinds of solvent-based adhesives and water-based adhesives, but the solvent-based adhesive is the main reagent because the water-based adhesive has a large surface tension. , low solid content, slow drying speed, insufficient bonding strength, etc. have not been well resolved, and s...
