Problems solved by technology

[0004] Since the water-based multi-color paint is a water-in-water multi-phase suspension system, the multi-color particles in the paint often appear bleeding, floating layer, sinking, shrinking, crushing, or excessive particle size during production and application, which directly leads to paint failure. The coating effect becomes poor and the color difference is large, which does not meet the production needs

Embodiment Construction

[0031] A kind of water-based colorful exterior wall paint, comprises the component of following percentage by weight:

[0032] Protective emulsion 45%, colorful particle suspension 55%;

[0033] The protective emulsion includes: 44.5% deionized water, 0.1% preservative, 2.0% film-forming agent Texanol, 0.2% defoamer A10, 0.2% pH regulator AMP-95, 2% propylene glycol, 50% silicone acrylic Emulsion, 1% thickener;

[0034] The colorful particle suspension is prepared by shearing and granulating the toning base material in the protective colloid solution;

[0035] Described protective colloid solution is the hydroxyethyl cellulose aqueous solution containing graphene oxide, and wherein graphene oxide content is 0.15%, and the content of hydroxyethyl cellulose is 3%;

[0036] The toning base material includes: 65% deionized water, 0.8% cellulose 250HBR, 1.5% propylene glycol, 0.2% dispersant 5040, 1% film-forming agent Texanol, 0.1% defoamer A10, 0.1% pH adjustment Agent AMP-95,...

Abstract

The invention discloses a water-based colorful outer wall coating. The water-based colorful outer wall coating is prepared from the following components in percentage by weight: 30 to 50% of protective emulsion, and 50 to 70% of colorful particle suspension liquid, wherein colorful particles are prepared by using a graphene oxide-containing hydroxyethyl cellulose water solution as protective glue; by adding the graphene oxide, the strength and dispersing stability of a hydroxyethyl cellulose protective film are greatly improved, and the color mixing, turbidity, extreme-pressure crushing and the like of the colorful particles are effectively overcome; by adopting a flaky structure of the graphene oxide, the thixotropic property of the protective glue solution is effectively improved, and the prepared colorful particle suspension liquid is clear and independent; the film forming matters in the continuous phase and dispersing phase of the protective emulsion using silicone acrylic emulsion as the main component are respectively acrylic resin with poor viscosity and poor density and is reasonable in distribution; the colorful particles are uniformly dispersed in the film forming matters, and the floating and settling conditions are effectively improved.

Description

technical field [0001] The invention relates to the technical field of water-based colorful paints, in particular to a water-based colorful exterior wall paint and a preparation method thereof. Background technique [0002] The main function of the exterior wall latex paint is to decorate and protect the building surface, so that the appearance of the building is neat and beautiful, so as to achieve the purpose of beautifying the urban environment, and at the same time, it can protect the exterior wall of the building and prolong its service life. [0003] Multi-color coatings are mainly used in imitation stone coatings, so they are also called liquid stone, also called imitation granite exterior wall coatings. When painting, luxurious, beautiful and colorful patterns can be obtained by one-time spraying. Water-based colorful paint is a new type of environmentally friendly architectural paint prepared by applying innovative colloid technology and a new color concept. It is ...
