[0034] 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;

[0035] 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 a water-based environment-friendly colorful texture paint and a preparation method thereof to solve the problems that the existing colorful paint contains an organic solvent, which makes the product toxic, flammable and pollutes the environment. Its composition is calculated in parts by mass: 30-50 parts of emulsion, 20-40 parts of colored particles, 0.5-1.5 parts of thickener, 0.4-0.8 parts of dispersant, 0.2-0.4 parts of wetting agent, 0.5-2 parts of propylene glycol , 0.2-0.5 parts of defoamer, 1-3 parts of titanium dioxide, 3-5 parts of talcum powder, 1-5 parts of calcium carbonate, 0.1-0.3 parts of neutralizer, 10-40 parts of demineralized water. The invention uses modified starch and pigments as raw materials to prepare colored granules, and uses colored granules and compound modified starch emulsion as raw materials to prepare environmentally friendly colorful particle coatings, which have the characteristics of environmental protection, no bleeding, good compatibility, good repeatability and the like.

Description

technical field [0001] The invention belongs to the field of environmental protection coatings, in particular to a water-based environmental protection colorful texture coating and a preparation method thereof. Background technique [0002] Multi-color paint is a composite suspension dispersion paint composed of granular substances of different colors, sizes and shapes that are incompatible with the paint. It usually contains two or more color particles, forming various color patterns. One-time construction can get colorful patterns with different shades and levels, and can receive remarkable decorative effects after use. Multi-color paint can be used to paint surfaces that require multiple colors, and the state of wallpaper can be simulated by using multi-color paint. Moreover, many applications of colorful paint cannot be replaced by wallpaper. For example, colorful paint can easily paint irregular surfaces, and can also be used for exterior wall painting. It has the c...
