Problems solved by technology

[0002] Water-in-water multi-color paint is a new paint product in recent years, which solves the problems of single color of traditional paint, high price of natural stone, heavy weight, and environmental pollution of oil-in-water colorful stone-like paint products. It has been widely used. However, in the construction of water-in-water multi-color stone-like coatings on the market, it is necessary to roll the colored primer and then spray the water-in-water multi-color paint to obtain the appearance of stone-like coatings. This process includes two constructions. The process, the construction process is complicated, and the construction period is long
[0003] China No. 201410401213.5, the patent titled "a kind of bottom-surface-in-one exterior wall latex paint" provides a coating with excellent alkali resistance and salt-out resistance, but the color of the bottom-surface-in-one exterior wall latex paint can only be It is a single color and cannot imitate the effect of natural stone
[0004] China No. 201310361127.1 patent titled "A Water-in-Water Multicolor Paint" provides a water-in-water multicolor paint whose continuous phase is a transparent emulsion without any hiding power, and must be constructed before applying the water-in-water multicolor paint The supporting latex paint can only show the imitation stone effect as a colored primer, which cannot solve the technical problems of the stone imitation effect of the existing paint and the construction process

preparation example Construction

[0094] Other embodiments of the present invention provide a method for preparing a bottom-surface-in-one water-in-water multicolor paint, the bottom surface-in-one water-in-water multicolor paint is the bottom surface-in-one water-in-water colorful paint described in any of the above-mentioned embodiments coating, comprising the steps of:

[0095] (1) Preparation of toning base paint for dispersed phase

[0096] Mix water, protective rubber powder, wetting agent, dispersant, defoamer, and bactericide, stir until uniform, slowly add titanium dioxide and filler, and disperse at a speed of 1000-1500 rpm for 10-15 minutes. Then add anionic emulsion, organic silicon surfactant, water, and film-forming aids, adjust the viscosity to 100-105 KU with a thickener, and prepare the toned base paint for later use;

[0097] (2) Preparation of protective colloid solution

[0098] Add the retarder to water, disperse until completely dissolved, then add the protective gel powder, disperse at...

Embodiment 1

[0106] The bottom surface of the present embodiment combines water-in-water multi-color paint, is made up of the toning base paint of dispersed phase, protective colloid solution and continuous phase color paint, the color between described toning base paint, protective colloid solution and continuous phase color paint The weight ratio is 30:40:30.

[0107] Components and weight ratio of the toning base paint of the dispersed phase: 3 parts of protective rubber powder, 0.2 part of wetting agent, 0.2 part of dispersant, 0.3 part of defoamer, 0.1 part of fungicide, 2 parts of titanium dioxide, filler 10 parts, 45 parts of elastic pure acrylic emulsion, 6 parts of silicone surfactant, 2 parts of coalescent, 0.2 parts of thickener, 31 parts of water.

[0108] Components and weight ratio of the protective colloid solution: 11 parts of protective colloidal powder, 4 parts of retarder calcium chloride, and 85 parts of water.

[0109] The synthetic emulsion in the continuous phase pa...

Embodiment 2

[0124] The main difference between this example and Example 1 is that the anionic emulsion of the toning base paint uses a modified silicon acrylic emulsion, and the continuous phase color paint uses a fluorocarbon emulsion, which can further improve the weather resistance of the coating.

[0125] In the bottom-surface-in-one water-in-water multicolor paint of this embodiment, the weight ratio between the toning base paint of the dispersed phase, the protective colloid solution and the continuous phase color paint is 30:35:35.

[0126] The components and parts by weight of the toning base paint of the dispersed phase are: 50 parts of modified silicone acrylic emulsion, 3 parts of protective rubber powder, 0.2 part of wetting agent, 0.2 part of dispersant, 0.3 part of defoamer, and 0.1 part of bactericide 1 part, 1 part of titanium dioxide, 12 parts of filler, 10 parts of hollow covering polymer, 2 parts of film-forming aid, 0.2 part of thickener, 21 parts of water.

Abstract

The invention provides a multicolor water-in-water primer-topcoat coating and a preparation method thereof. The coating comprises disperse-phase color matching basic paint, a protection glue solution and continuous-phase colored paint in the weight ratio being (30-40): (30-40): (20-30). According to the multicolor water-in-water primer-topcoat coating, colored primer is not required to be applied in advance, a multicolor continuous coating with a stone-simulating effect can be obtained only through one-time spraying, and the coating is an ideal alternative of decorative stone materials such as marble, granite and the like. The coating is an all water-based product, contains few VOCs (volatile organic compounds), doesn't contain APEO (alkylphenol ethoxylates), is environment-friendly and free of pungent smell and has excellent weather fastness, and the performance of the product meets the requirements of the HG/T4343-201 water-based multicolor building coating standard.

Description

technical field [0001] The invention relates to an architectural coating for interior and exterior walls, and more specifically relates to a bottom-surface-integrated water-in-water multicolor coating and a preparation method thereof. Background technique [0002] Water-in-water multi-color paint is a new paint product in recent years, which solves the problems of single color of traditional paint, high price of natural stone, heavy weight, and environmental pollution of oil-in-water colorful stone-like paint products.
