Description
Technical Field
The invention relates to the field of coatings, and particularly relates to a hydrophobic stone-like paint and a preparation method thereof.
Background
With the development of society, people pay more attention to the decorative performance of the paint while paying attention to the environmental protection performance of the building paint, so that the vigorous development of emulsion paint, real stone paint, texture paint, granite paint and multicolor paint is promoted. However, the corrosion and pollution of the coating surface become more and more serious due to the increased environmental pollution and frequent acid rain. Therefore, how to improve the stain resistance and self-cleaning performance of the exterior wall becomes a critical problem to be solved by coating practitioners. The current self-cleaning approaches include 2 types: a superhydrophilic coating and a superhydrophobic coating. The super-hydrophilic coating utilizes the principle of titanium dioxide photocatalysis and super-hydrophilic characteristics, so that rainwater can form film-shaped scouring on the surface of a paint film on the premise of sufficient rainwater, thereby having the self-cleaning characteristic. The contact angle between the surface layer of the super-hydrophobic coating and water is more than 150 degrees, the sliding angle is less than 5 degrees, because water drops are difficult to adhere to the surface of the coating, the water drops easily roll and slide on the surface and take away pollutants, the self-cleaning effect can be achieved, and the self-cleaning function is also called as the lotus effect "
How to further improve the hydrophobic property, improve the adhesive force of the coating, and avoid the phenomenon that the real mineral varnish turns white when meeting water is an urgent technical problem to be solved in the industry.
