Abstract

The invention discloses a water white resistant stone-like coating which is prepared from the following components: water-based acrylic emulsion, a film forming auxiliary, a defoaming agent, cellulose ether, color sand, silicon sol, corn hydroxypropyl starch and modified calcined clay. The stone-like coating disclosed by the invention is high in film forming property and cannot crack; under conditions of low temperature (4 to 6 DEG C) and high humidity (70 to 80 percent), the stone-like coating has outstanding advantages that the coating can be dried after being constructed within a short period of time (1.5 hours) and is not whitened in water.

Description

technical field [0001] The invention belongs to the technical field of real stone paint, and in particular relates to a water-resistant white real stone paint. Background technique [0002] At present, there are many kinds of decorative coatings. Real stone paint is a kind of imitation stone paint formulated with various colors of stone powder, emulsion and additives. It not only has a decorative effect similar to marble and granite, but also has strong decorative properties. , wide application, good durability, not easy to fade and other characteristics, so it is a kind of popular exterior wall decoration paint. In the construction and application of real stone paint, some problems that affect the quality and decorative effect often appear, such as the coating becomes white when it meets water, which reduces the surface decoration and service life of real stone paint. Contents of the invention [0003] The object of the present invention is to provide a water-resistant w...
