Problems solved by technology

Not only does it require greater labor intensity and higher labor costs during construction, but there are also problems such as blooming and whitening caused by the matching difference between the real stone paint and the finish paint.
At the same time, the water resistance and stain resistance of the real stone paint prepared by the prior art are relatively poor, which seriously affects the decorative effect of the real stone paint as an exterior wall coating.

Abstract

The invention relates to a functional real stone paint building exterior wall coating material and a preparation method thereof. The functional real stone paint building exterior wall coating material is composed of the following components in parts by weight: deionized water, hydroxyethyl cellulose, an aqueous multifunctional addition agent, a real stone paint special silicone acrylic emulsion, a coalescing agent, an aqueous defoamer, a sterilizing corrosion remover, a hydrophobing agent and natural colored sand. The functional real stone paint building exterior wall coating material prepared by the invention is formed with one construction process and strong in covering power with surface covering-free performance, simultaneously is excellent in water resistance, stain resistance and weather resistance performance.

Description

technical field [0001] The invention relates to a coating for exterior wall decoration, in particular to a functional genuine stone paint building exterior wall coating and a preparation method thereof. Background technique [0002] Exterior wall coatings are used to paint the exterior walls of buildings. There are many types of exterior wall coatings. Among them, according to the decorative texture, it can be divided into thin exterior wall coatings, multi-layer pattern coatings, colored sand coatings and thick coatings. Real stone paint is one of the thick coatings. With the development in recent years, real stone paint can reduce the weight of the wall by 90%, save about 90% of the construction cost, and imitate the natural stone effect vividly, vividly, without the danger of falling, etc., as a building exterior wall Coatings are widely used. Now the real stone paint construction technology used on a large scale is mainly two coats of real stone paint, plus two coats o...
