Abstract

The invention relates to a flexible true stone paint which comprises the following components: water, non-ionic water soluble cellulose ether, a waterborne multifunctional additive, a defoaming agent, a dispersing agent, a wetting agent, acrylic composite emulsion modified by organo-siloxane, elastic acrylate emulsion, a coalescing agent, a complex solubilizer, an antibacterial preservative, a rheological agent and aggregates. The flexible true stone paint disclosed by the invention overcomes the defects of relatively insufficient toughness, high cracking possibility of a paint film and poor stain resistance of an existing true stone paint, and has the advantages of outstanding flexibility, good cracking resistance, and excellent water resistance, weather resistance and stain resistance.

Description

technical field [0001] The invention relates to a flexible real stone paint and a preparation method thereof, which are applied in the field of architectural decoration paints. Background technique [0002] Due to its safety, environmental protection, low price, and rich colors, the share of real stone paint in the field of exterior wall decoration protection has been increasing year by year. At present, the polymer emulsion used in general real stone paint is mostly styrene-acrylic emulsion with high glass transition temperature. The film has high strength, but its relative toughness is not enough. It tends to be brittle at low temperature and after long-term use. There is a risk of freezing and cracking after repeated impacts by the stress of the base layer, especially in areas with significant cold and temperature differences. In addition, the paint film of real stone paint has poor compactness, large mechanical pores, low glass transition temperature of flexible emulsion...
