Problems solved by technology

[0002] At present, most exterior wall paints are mainly organically synthesized emulsions, which are easy to construct, rich in decoration and color, but harmful substances volatilize during production and construction, and have excellent performance in weather resistance, heat and humidity resistance and adhesion. Poor, easy to be affected by ultraviolet rays and aging
Moreover, the dense coating seals the wall and prevents water vapor from penetrating, causing shedding.
However, pure inorganic coatings have disadvantages such as poor stability and poor decoration, which is not convenient for large-scale promotion and use.
[0003] CN101117477A discloses a preparation method of organic-inorganic composite waterproof paint, but there are many raw materials involved in the reaction, the content of components is not easy to control, and the process steps are relatively complicated
[0004] CN104559507A discloses an organic-inorganic composite coating and its preparation method, which has good water resistance, alkali resistance and stain resistance, but other performance needs to be further improved

Abstract

The invention provides organic and inorganic compound waterborne paint for exterior walls and a preparation method thereof. The paint comprises waterborne synthetic resin, an inorganic cementitious material, a stabilizing agent, an auxiliary agent, a pigment and filler, and water, wherein the waterborne synthetic resin is pure acrylic emulsion modified by ultraviolet crosslinking, the inorganic cementitious material is a mixer of silicate and silica sol, and the stabilizing agent is siloxane. The organic and inorganic compound waterborne paint for exterior walls has good film forming effects, appropriate flexibility, extremely good adhesive force for surface of an object, good stability, as well as extremely good weatherability, wear resistance, and moisture and heat resistance; and the paint can satisfy demands of multiple respects.

Description

technical field [0001] The invention relates to the field of chemical materials, in particular to the field of coatings, in particular to an organic-inorganic composite exterior wall water-based coating and a preparation method thereof. Background technique [0002] At present, most exterior wall paints are mainly organically synthesized emulsions, which are easy to construct, rich in decoration and color, but harmful substances volatilize during production and construction, and have excellent performance in weather resistance, heat and humidity resistance and adhesion. Poor, easy to receive ultraviolet light and aging. Moreover, the dense coating seals the wall and prevents water vapor from penetrating, resulting in shedding. However, pure inorganic coatings have the disadvantages of poor stability and poor decoration, which are not convenient for large-scale promotion and use.
