A self-cleaning real stone paint with glass beads as aggregate and preparation method thereof

Abstract

The invention relates to a self-cleaning real stone paint with glass microspheres as aggregates and a preparation method thereof, comprising: 15-25% of water-based carbon-titanium cage resin; 60-70% of natural quartz sand and modified glass microspheres; superhydrophobic nano Silicon dioxide 1‑2%; organic surface modified nano-titanium dioxide 1‑2%; expanded vitrified bead insulation mortar 2‑3%; wetting agent 0.01‑0.1%; dispersant 0.01‑0.5%; defoamer 0.01‑0.05%; coalescent 0.05‑0.5%; thickener 0.1‑0.3%; water balance. In the present invention, water-based carbon-titanium cage resin, modified glass beads are used for modification, modified nano-titanium dioxide is used for modification, and bacteria liquid containing Bacillus pasteurium is sprayed on the surface of natural quartz sand to cooperate, thereby effectively avoiding the use of hydroxyl Ethyl cellulose, the obtained real stone paint still has good viscosity and rheological properties. The real stone paint of the present invention has excellent stain resistance, excellent water whitening resistance, can overcome the phenomenon of rain marks, and has good color retention and durability, no blooming phenomenon, easy construction, no obstacles in spraying, and small film-forming shrinkage , not falling.

Description

technical field [0001] The invention relates to the technical field of architectural coatings, in particular to a self-cleaning real stone paint with glass beads as aggregate and a preparation method thereof. Background technique [0002] With the acceleration of industrialization and urbanization and the rapid increase of various vehicles, the air pollution is becoming more and more serious. The air contains a lot of dust, oil and other pollutants. These pollutants are easy to adhere to the outer walls of buildings. The exterior wall of the building becomes gray and old; and the pollutants deposited on the plane structure of the building such as window sills, terraces, etc. will also pollute the exterior wall of the building under the action of rainwater, seriously affecting the appearance of the building and the quality of decorative materials. Decorative effect increases the cost of building wall cleaning and maintenance. At present, a large amount of financial, material...

Problems solved by technology

However, cellulose has poor water resistance and is prone to mildew, which causes the real stone paint film to turn white when exposed to water, and makes the real stone paint easy to mildew and deteriorate during storage; Thinning, small sand particles and emulsions move closer to the bottom layer, and large sand particles gradually protrude from the surface, causing the decorated wall to bloom due to the color difference between coarse and fine sand particles
