Problems solved by technology

This kind of real stone paint often has slow drying speed, high VOC content, and poor environmental protection performance; poor stain resistance, if the dust in the air is adsorbed on the surface of the real stone paint to be coated, it is difficult to be washed away by rain; poor weather resistance , the real stone paint film is difficult to achieve long-term protection effect on the protection and decoration of the painted buildings.

Abstract

The invention discloses an environment-friendly weather-proof fouling-proof stone-like paint and a preparation method thereof. By taking a hydrophilic type self-crosslinked pure acrylic emulsion as a main binder base stock, compounding an elastic emulsion, adding an ultraviolet light-shielded functional type nanomaterial including nanozinc oxide and nano titanium dioxide and grading natural colored sand, the weather resistance and stain resistance of the stone-like paint can be remarkably promoted. All performance indexes can achieve or exceed the requirement of the construction industrial industry standard JG / T24-2000, and key performances are far superior to the specified values of the standard.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to an environment-friendly weather-resistant and anti-fouling real stone paint and a preparation method thereof. Background technique [0002] Real stone paint, also known as imitation stone paint, colored glaze quartz sand paint, the construction industry standard is called synthetic resin emulsion sand wall architectural paint, which is based on synthetic resin emulsion and natural colored sand with different particle sizes as aggregate. Thick architectural coatings prepared with various additives. Its decorative effect is similar to white marble, marble or granite, with the natural luster of natural real stone, graceful and luxurious, solemn and elegant, and can fully display the rich texture of natural stone. Compared with traditional pasted tiles and dry-hanging stone materials, real stone paint is being developed more and more due to its remarkable advantages such...
