Abstract

The invention discloses a preparation method of a real stone lacquer not prone to fall sands. The method comprises the following steps: (1) flushing natural color sands with water, immersing the flushed natural color sands in a modification solution, and performing filtration to obtain modified natural color sands; (2) adding nonenylsuccinic anhydride into a silicone acrylic emulsion, performing mixing and uniform stirring, and standing the obtained solution; and (3) adding a polyurethane leveling agent, an antifoaming agent and a film forming additive into deionized water, performing mixing and uniform stirring, adding the obtained solution into the silicone acrylic emulsion, uniformly stirring the obtained solution by a mixer, adding the modified natural sands, and performing mixing andstirring to prepare the finished product. The preparation method of the real stone lacquer not prone to fall sands has the advantages of simplicity in operation, and low cost, and the prepared real stone lacquer has the advantages of strong stability, no layering phenomenon in the storage process, excellent construction performances, excellent resistance to water, corrosion and aging, no sand falling especially after being dried, and maintenance of the decoration and protection effects for a long time.

Description

technical field [0001] The invention belongs to the technical field of preparation of real stone varnish, and in particular relates to a preparation method of real stone varnish which is not easy to drop sand. Background technique [0002] Real stone paint is based on one or more synthetic resin emulsions, adding a small amount of film-forming aids as bonding materials, using different grades of natural colored sand or artificial sand as aggregates, and adding dispersants and defoamers in a quantitative manner. A series of additives such as fungicides, multifunctional additives, thickeners, etc., are prepared by adding quantitative deionized water to a high-quality, high-performance architectural coating with a decorative effect similar to marble, granite and other stone materials. The color of the finished product of real stone paint comes from the color of natural colored sand. The color of the product can be adjusted through the matching of different meshes of colored san...
