Problems solved by technology
[0004] Aiming at the deficiencies of the prior art, the present invention provides a water-in-water multi-color paint and its production process, which solves the problem that the reaction time is very long, basically more than 24 hours, and the water-in-water multi-color paint is affected by the viscosity during actual use. The large pores between the coatings will cause the surface of the coating to appear rough and uneven, resulting in a small density between the molecules of the coating. After the coating is subjected to external impact or corrosive objects, it is prone to delamination, peeling, etc. phenomenon, thus affecting the tightness and aesthetics of the coating

Abstract
The invention discloses a water-in-water multicolor coating. The paint is prepared by mixing a component A, a component B and a component C, the component A is prepared from 45 percent to 65 percent of deionized water, 0.6 percent to 1.2 percent of polyacrylate, 1 percent to 3 percent of a water-based auxiliary agent, 5 percent to 15 percent of filler, 20 percent to 35 percent of a silicone acrylic emulsion and 0.2 percent to 1.0 percent of lithium magnesium silicate; the component B is prepared from 90 percent to 95 percent of deionized water, 5 percent to 8 percent of magnesium lithium silicate and 0.1 percent to 1 percent of sodium benzoate; the component C is prepared from a self-made silicone acrylic emulsion. The invention discloses the water-in-water multicolor coating and a production process thereof. According to the water-in-water multicolor coating and the preparation method thereof, the silicone acrylic emulsion is used in cooperation with other auxiliaries, so that when the water-in-water multicolor coating is prepared, the viscosity of the coating can be adjusted without adding any thickening agent, meanwhile, color particles in the multicolor coating are suspended inthe paint, the preparation efficiency of the coating is improved, and meanwhile, the water whiteness resistance and uniformity of the coating are improved.
Description
technical field [0001] The invention relates to the technical field of building exterior wall coatings, in particular to a water-in-water multicolor coating and a production process thereof. Background technique [0002] Water-in-water colorful paint is made of modified resin and pigment with good stability developed by high-tech. It is fully water-based, colorful granite paint for one-time spraying, and the color produced is more realistic and durable. According to the designer's requirements Granite samples, the degree of simulation can reach 99%, is the best product to replace granite for exterior walls. [0003] The water-in-water on the market basically adds a large amount of thickener to suspend the color particles in the system, resulting in water-resistant whitening, unstable storage or adding self-thickening emulsion to increase the viscosity of the system, but the reaction time is very long, basically need For more than 24 hours, the preparation progress of the wa...
