Water-based colorful architectural coating and preparation method thereof

Abstract

The invention relates to a water-based colorful architectural coating and a preparation method thereof, belongs to building materials, can enable an external wall to obtain a marble visual effect through painting the water-based colorful architectural coating, and overcomes the defects that through the conventional coating, the marble visual surface cannot be obtained, and during dry hanging of a marble slab, the cost is high, and the safety is poor. The water-based colorful architectural coating comprises protecting rubber powder, latex, titanium white pulp, water, a plural gel, kaolin, a film-forming additive, a thickening agent and proper quantities of high-grade water dispersible pigments, wherein the plural gel comprises a suspending agent, a sizing agent and a gel according to corresponding proportion. The preparation method comprises the following steps: preparing protecting rubber solution, preparing a base coating, preparing a continuous phase, and pelleting to obtain the water-based colorful architectural coating. The water-based colorful architectural coating and the preparation method have the positive effects that the water-based colorful architectural coating is suitable for wall outer layer decorative surfaces, has high simulation, can not only simulate granite, but also embody the decorative effects of natural marbling and lines through adjusting the content of the protecting rubber solution and kaolin, and meanwhile has the advantages of low cost, environmental protection, energy conservation, superstrong self-cleaning function, cracking resistance, short construction period and long service life.

Description

technical field [0001] The invention belongs to the field of architecture, and in particular relates to a coating for exterior walls of buildings. Background technique [0002] Domestic existing water-in-water coatings for exterior wall decoration can only imitate simple decorative patterns such as granite, and complex and rich decorative patterns and lines such as natural marbles have not yet been released. In order to obtain the decorative effect of marble on the exterior wall of the building, only dry-hanging marble slabs are available. Not only is the cost high and the construction is difficult, but it is also used in the exterior surface decoration of the wall with the EPS exterior wall insulation layer. Damage to the insulation layer or fall off by itself poses a safety hazard.
