[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...

Embodiment 1

[0035] Example 1. Aggregate (red) for texture paint preparation:

[0036] The amount of raw materials for the aggregate is as follows: 50 kg of cement, 10 kg of lime, 15 kg of gypsum, 10 kg of fine sand (100 mesh), 20 kg of biomass binder, 8 kg of red water-based color paste, and 8 kg of demineralized water.

[0037] Aggregate preparation method:

[0038] a) Mix the water-based color paste and the biomass binder uniformly in parts by mass to obtain a mixed solution, which is set aside;

[0039] b) Add cement, lime, gypsum and fine sand into the mixer in parts by mass, and stir the mixture evenly;

[0040] c) Add the mixture obtained in step b to the water-based color paste and binder mixture prepared in step a, and stir well; d) Granulate the substance obtained in step c with a rotary granulator to prepare a granule with a particle size of 2.5 mm. Granules, dried, sized and sieved to obtain aggregate.

Abstract

The invention discloses a texture coating and a preparation method thereof and aims to solve the problems that the existing texture coatings are produced by using artificial color sand and are bad in weather resistance. The texture coating disclosed by the invention is made from aggregate, emulsion and other auxiliaries. The preparation method comprises the following steps: uniformly mixing cement, lime, gypsum, fine sand, waterborne color paste and biomass adhesive, and granulating to obtain the aggregate; and adding softened water, a thickener and a dispersing agent, uniformly stirring and dispersing in a dispersion machine, sequentially adding the emulsion, a film forming auxiliary, the aggregate, propylene glycol, a defoamer and preservative, uniformly stirring and dispersing to obtain the texture coating. The texture coating is friendly to environment and free of formaldehyde and has the characteristics of fire prevention, damp prevention, sound insulation, high strength, good weather resistance and the like.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a textured coating and a preparation method thereof. Background technique [0002] The development direction of architectural exterior wall coatings is high decoration, strong stain resistance, high durability, resource saving, energy saving, pollution-free and pollution-free. From the perspective of decoration, stain resistance and durability, solvent-based coatings are relatively easy to meet the requirements, but their air permeability and environmental protection requirements are difficult to meet. From the perspective of environmental protection, the generally accepted approach is water-based, but the stain resistance and aging resistance of water-based coatings are usually difficult to compare with solvent-based coatings. [0003] With its infinitely varied three-dimensional textures, textured paints can be matched with multiple choices of personality. It can replace s...
