Technical Field

The invention relates to the technical field of coatings, in particular to a high-performance waterproof antifouling real stone paint.

Background

In order to achieve the effect of natural stone materials in the existing buildings, natural stone materials are commonly used, but the natural stone materials are limited by natural ores, are not uniform in color and pattern after decoration, cannot be renovated, and are difficult to mine and process and expensive; the unit volume weight is large, the load on the wall body is large, the wall body is not suitable for the decoration of light buildings, in addition, the construction difficulty is large, particularly, corner parts need special processing treatment, joint sealing glue needs to be added into gaps among the stones, and the whole waxing needs to be carried out after the construction is finished.

The spraying effect of the real stone paint is solemn and elegant, rich texture of natural stone can be fully displayed, and the natural broken stone is adopted to display the characteristics that the color is never faded, the long-term beautiful texture of the wall body is kept, and the like. The stone-like paint has wide application, and the decorative effect is comparable to that of stone, and is more suitable for moulding various artistic models than that of stone, and can be used as exterior wall, relief, beam column and other special-shaped wall surface decorations, and is suitable for making exterior wall paintings, and has granite, marble and granite color effects, and can obtain the effect of being fake and unreal. The traditional stone paint adopts a cellulose thickener, and a large amount of hydroxyl functional groups on the surface of the thickener greatly reduce the water and stain resistance and the water resistance of the stone paint (Guoqingquan, Riyongjin, Chengju. the stain resistance and the influence factor [ J ]. green building, 2003, 19(5): 15-18.), so that the surface of the stone paint is easy to be polluted and easy to fall off from an outer wall cavity in a humid environment.
