Lithium silicate interior and exterior wall coating and preparation method thereof

Abstract

The application discloses a kind of lithium silicate inner and outer wall paint and preparation method thereof, comprising the following raw materials: water, hydroxyethyl cellulose, dispersing agent, wetting agent, defoaming agent, attapulgite, diatomite, calcined kaolin, heavy calcium carbonate, titanium white, humectant, acrylic emulsion, modified lithium silicate resin, thickening agent and film-forming aid.Modified lithium silicate resin is modified lithium silicate resin after silane coupling and hydrolysis, with high strength, high strength and self-drying film-forming characteristics, fundamentally avoiding the phenomenon of efflorescence caused by wall surface efflorescence caused by paint itself.The lithium silicate-based inorganic paint produced with the emulsion as base material fully reaches the performance indicators of inorganic paint, significantly improves the aesthetic effect of wall, and also improves the weather resistance and stability of the paint.The preparation method of the paint has simple steps and mild reaction conditions, and is suitable for large-scale production and preparation.
