Abstract

The invention relates to finish-coat paint for real stone paint, wherein the finish-coat paint is prepared from the following components in parts by weight: water, a germicidal and anti-corrosion agent, bentonite, an aqueous solution of 2-amino-2-methyl-1-propanol with mass concentration of 90-95%, a defoamer, a dispersant, a wetting agent, a lotus leaf hydrophobing agent, lotus-leaf-effect organosilicone hydrophobic emulsion, a coalescing agent, a cosolvent, the defoamer, a thickening agent and a rheological auxiliary. The finish-coat paint for the real stone paint overcomes the defects that the existing finish-coat paint for the real stone paint is poor in stain resisting effect and is free from self-cleaning ability, and has the advantages that excellent hydrophobicity, excellent stain resistance and a photocatalystic self-cleaning function are achieved, and the service life of the real stone paint can be prolonged.

Description

technical field [0001] The invention relates to a finish paint for real stone paint and a preparation method thereof, which are applied in the field of paint for architectural decoration. Background technique [0002] Due to the poor surface density and large mechanical pores of the real stone paint, the coating is easily stained, and the pollutants easily penetrate into the paint film, so it is difficult to remove it by secondary cleaning. In addition, styrene-acrylic emulsion is often used as a film-forming material in real stone paint, and the paint film has poor weather resistance and is prone to yellowing and chalking after being irradiated by ultraviolet rays. In order to improve the aging resistance of real stone paint, it is generally necessary to use varnish for finishing. Existing varnishes for real stone paints have poor stain resistance and self-cleaning ability. Therefore, it has become urgent to provide a finish paint for real stone paint with good hydrophobi...
