Problems solved by technology

However, alkali-swellable thickeners are highly hydrophilic, which will affect the water resistance of colorful coatings, and the coatings will appear whitening and foaming when exposed to water.
There are also some colorful paints that use acrylic emulsion to thicken the continuous phase to increase the viscosity. However, the thickening effect of acrylic emulsion is difficult to control, which is not conducive to the stable storage of colorful paints.

preparation example Construction

[0059] The preparation method of the self-thickening colorful paint includes the following steps S100-S300.

[0060] Step S100: Mix and granulate the base paint and the granulation solution to prepare color dots.

[0061] Step S200: thickening the colored dots by mixing with the self-thickening continuous phase.

[0062] Step S300: mixing the inactive continuous phase with the colored dots thickened by mixing and the self-thickening continuous phase.

[0063] The above-mentioned self-thickening colorful paint includes base paint, granulation liquid, self-thickening continuous phase and inactive continuous phase, and the color dots are mixed with self-thickening continuous phase and inactive continuous phase step by step, and the protective glue can be formed with the continuous phase Directional and controllable self-thickening reaction, controllable viscosity of coating, good storage stability. The matting powder and talcum powder in the self-thickening continuous phase and...

Abstract

The invention relates to self-thickening multicolor coating and application thereof. The self-thickening multicolor paint comprises base paint, a granulation liquid, a self-thickening continuous phase and a non-active continuous phase according to a specific component ratio, color points prepared from the base paint and the granulation liquid are mixed with the self-thickening continuous phase and the non-active continuous phase step by step, protective glue and the continuous phase can be subjected to a directional controllable self-thickening reaction, the viscosity of the paint is controllable, and the storage stability is relatively good. Matting powder and talcum powder in the self-thickening continuous phase and the non-active continuous phase have relatively good dispersion suspension property and can play a synergistic role with an emulsion in a coating system, so that the storage stability of the coating is improved, and the problems of storage layering, construction sagging and the like of the multi-color coating are solved. According to the self-thickening multi-color paint, an alkali swelling thickening agent is not used, so that the paint is good in water resistance, and is not easy to whiten and blister when meeting water.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a self-thickening colorful coating and its application. Background technique [0002] Water-in-water multicolor paint keeps pace with real stone paint in the field of building exterior walls. It is one of the two most widely used exterior wall paints at present. It has the advantages of high cost performance, environmental protection, light weight, and realistic imitation of stone effects. [0003] Colorful paint is a metastable multi-phase system obtained by uniformly dispersing color dots in the continuous phase. In order to simulate the stone effect and facilitate granulation, pigments and fillers such as titanium dioxide are added to the color dots; while the continuous phase requires uniformity and transparency. The color and shape of the colored dots can be displayed to the maximum extent, so the proportion of the colored dots is higher than that of the continuous phase. ...
