[0028] 3. The preparation process of acid hydrolyzed hydroxypropyl starch is as follows: in deionized water, add a swelling inhibitor relative to the starch mass ratio of 13%, add sodium hydroxide accounting for 1.0% of the starch mass, mix and stir until dissolved, and add the step (1) Adjust the prepared acid-thinned starch into 35% starch milk, stir and alkalinize for 40 minutes, heat up to 42°C, add propylene oxide accounting for 5% of the starch mass, etherify for 14 hours, add 10% hydrochloric acid to adjust the pH to 7.0, after centrifugal dehydration, drying and sieving, the acid hydrolyzed hydroxypropyl starch can be obtained;

[0029] 4. The preparation process of acid-thinned starch used in the preparation process of acid-thinned carboxymethyl starch and acid-thinned hydroxypropyl starch is as follows: add HCl solution with a mass percentage concentration of 0.6% to the starch, and prepare starch with a concentration of 38%. Milk, heated to 50°C, acidolysis for 2 ho...

Abstract

The invention discloses biomass environment-friendly water-based color paste and a preparation method thereof, and aims to solve the problems of single function, poor storage stability and low color keeping degree in the conventional water-based color paste. The preparation method of the biomass environment-friendly water-based color paste comprises the following steps: dispersing an inorganic or metal pigment, a composite modified starch emulsion, a dispersing agent, a biomass stabilizer, a moistening agent, aluminum starch dodecenyl succinate and a pH adjusting agent for a certain period of time, and grinding the mixture; and adding an antifoaming agent, stirring the mixture uniformly at a low speed, filtering the mixture, and packaging the filtered mixture to obtain a biomass water-based color paste product. The product prepared by using the preparation method can be applied to coating, printing and advertising ink jet, and has the characteristics of environmental friendliness, stability, high color retention and the like.

Description

technical field [0001] The invention belongs to the field of latex paint color paste preparation, and in particular relates to a biomass environment-friendly water-based color paste and a preparation method thereof. Background technique [0002] Water-based color paste refers to the concentrated pigment paste formed by organic or inorganic pigments under the wetting and dispersing action of surfactants, which is uniform and stable, has certain fluidity or thixotropic fluidity, and strong coloring strength. Water-based color paste is used for coloring, and its application fields include coatings, printing, papermaking, textiles and other industries. At present, it is mainly used in the paint industry, and the pigment exists in a liquid state, which makes the paint production simple and easy to operate. [0003] Existing water-based color pastes generally have single functions: they can only be used for water-based paints, mainly for factory coloring of latex paints; they hav...
