Waterborne exterior-wall paint and its preparation method

Abstract

The invention relates to a waterborne exterior-wall paint and its preparation method. The paint comprises the following components: by weight, 20-50% of water, 15-45% of a nano-modified fluoropropionate emulsion, 1-20% of nano-modified polymer, 2-20% of rutile titanium dioxide, 1-10% of wollastonite powder, 1-10% of meerschaum powder, 0.2-10% of mica powder, 1-6% of glycol and a conventional auxiliary agent. The paint provided by the invention can be made into texture-type exterior-wall paint of different types and different colors. The paint film has characteristics of high weatherability, scrub resistance, stain resistance, high hardness, strong adhesion, good hydrophobicity, excellent ageing resistance and the like.

Description

Technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to a water-based exterior wall paint and a preparation method thereof. Background technique [0002] Wall brick is an effective decorative element of the wall. However, the state stipulates that high-rise buildings cannot use wall brick. Therefore, exterior wall paint has emerged to replace the decorative effect of wall brick. The exterior wall paint is mainly used to decorate and protect the exterior wall of the building, make the appearance of the building clean and beautiful, so as to achieve the purpose of beautifying the urban environment; at the same time, it can protect the exterior wall of the building, extend the use time, and obtain a good Decoration and protection effect. Because exterior wall coatings are directly exposed to nature and withstand the attack of wind, rain and sun, the coatings are required to have water resistance, color retention, pollution resistan...
