Abstract

The invention provides a preparation method of a water-based ink vehicle. The preparation method comprises the following steps: (1), mixing nanometer silicon dioxide, molybdenum disulfide, vinyltriethoxysilane, gamma-aminopropyltrimethoxysilane and ethyl acetate, and stirring for 20-40 minutes at the speed of 300-500 r / min; (2), adding fructone-B, dispersing rosin size and ethylene glycol diglycidyl ether, and performing ultrasonic shearing for 5-10 minutes; (3), adding hydroxypropyl methylcellulose, casein, lauramidopropyl betaine, sodium dodecyl benzenesulfonate, dihydroxymethyl butyric acidand distilled water, heating to 40-70 DEG C, and stirring for 10-30 minutes; and (4), standing for defoaming, sieving by using a 100-mesh sieve to remove a filter residue to obtain the water-based ink vehicle. By the preparation method of the water-based ink vehicle, the prepared ink vehicle has very strong adhesion, high hardness performance and high water resistance.

Description

technical field [0001] The invention relates to a preparation method of water-based ink binder. Background technique [0002] Ink has a great impact on the environment, and harmful ingredients in ink will directly endanger human health. Water-based ink is a low-toxicity ink, which is mainly composed of water-based binders, organic pigments, water and related additives through physical and chemical processes. become. As the most important component of water-based ink, the quality of water-based ink binder directly affects the performance of water-based ink. Initially, natural resins such as dextrin, shellac and starch were mainly used as water-based ink binders. The prepared water-based inks were mainly used for printing low-end products, and the gloss, water resistance and adhesion of printed products were poor. With the advancement of science and technology and the improvement of ink performance requirements in various industries, it has become an irresistible trend to re...
