preparation example Construction

[0050] A preparation method of the water-based multi-color paint of the drawing, specifically comprising the following steps:

[0051] Step 1. Preparation of base paint:

[0052] 1) Inject deionized water into the disperser and heat to 80-90°C;

[0053] 2) Start the disperser, adjust the rotation speed to 400-800r / min, weigh and add polyvinyl alcohol, and disperse evenly. The dispersion time is 10-20 minutes, and the polyvinyl alcohol is completely dissolved;

[0054] 3) Weigh and slowly add kaolin and titanium dioxide in sequence, adjust the speed of the disperser to 1400-1600r / min, and disperse evenly for 15-25 minutes;

[0055] 4) Weigh and slowly add the resin emulsion, and adjust the speed of the disperser to 800-1200r / min, and disperse for 4-6 minutes;

[0056] 5) Weigh and slowly add a protective glue solution with a mass fraction of 9%, and disperse evenly for 10-20 minutes to obtain a white base primer;

[0057]6) Take out the white basic primer, add an appropriate...

Abstract

The invention discloses cobwebbing waterborne colorful coating and a preparation method thereof. The cobwebbing waterborne colorful coating is prepared from mixing of base coating, protective colloidal solution with a mass fraction of 5% and a continuous phase. The base coating is prepared from, by weight, 35-50 parts of deionized water, 5-10 parts of polyvinyl alcohol, 0.5-2 parts of kaolin, 0.1-1 part of titanium dioxide, 20-30 parts of resin emulsion, 25-40 parts of protective colloidal solution with the mass fraction of 9% and 0.5-2 parts of color paste. The continuous phase is prepared from, by weight, 40-60 parts of resin emulsion, 40-60 parts of deionized water, 2-5 parts of a coalescing agent, 0.1-0.5 part of functional additives and 0.5-1 part of alkali swelling thickening agent.A mass ratio of the base coating, the protective colloidal solution with the mass fraction of 5% and the continuous phase is (1-2):(1-2):1. The cobwebbing waterborne colorful coating is excellent in performances of thixotropy, thickening, leveling and the like.

Description

technical field [0001] The invention relates to a water-based colorful paint in a drawing shape and a preparation method thereof. Background technique [0002] Multi-color coatings are mainly used in imitation stone coatings, so they are also called liquid stones, also called imitation granite exterior wall coatings. They are composed of incompatible two-phase components, one of which is a continuous phase and the other is a dispersed phase. When painting, luxurious, beautiful and colorful patterns can be obtained by one-time spraying. The particles of conventional colorful paints are mainly round dots, forming the final paint film shape mainly in dots. [0003] At present, the market is basically presented in the form of such round particles, which causes visual fatigue to consumers, and generally multi-color coatings require a large amount of powder-supported base paint, resulting in high cost; Formed a sense of abruptness. [0004] Therefore, in the colorful paint mark...
