Wall finishing paint containing nanomaterial

Abstract

The invention relates to a wall finishing paint containing a nanomaterial. The wall finishing paint contains the following ingredients: 10-25% of nano calcium carbonate, 5-10% of nano titanium dioxide, 20-30% of resin emulsion, 2-5 parts of thickener, 2-4% of propanediol and the balance of deionized water, wherein the grain diameter of the nano calcium carbonate and the nano titanium dioxide is 20-60 nm. The wall finishing paint containing the nanomaterial, provided by the invention, has the advantages of good color retention, excellent adhesive power, hydrophobicity, self-cleaning performance and super weatherability, a whole production process and a preparation method of products are simple in operation, and the industrial production is easy; and a nano-silicon wall finishing paint has the characteristics of good adhesive power, scrub resistance, weatherability, ageing resistance, antisepsis, ultraviolet resistance and the like, and the performances, such as self-cleaning performance, waterproof and anti-seepage performance, anticorrosion and color retention, of the paint are remarkably improved.

Description

technical field [0001] The invention relates to a wall paint, in particular to a nano material wall paint. Background technique [0002] Wall paint is a protective and decorative water-based paint applied to the walls of houses, apartments, hotels and other buildings. It has a wide range of applications, is easy to use, non-toxic and environmentally friendly. However, most wall paint coatings have insufficient stain resistance, are prone to aging, discoloration, and poor durability. Especially in the northern region, in order to prevent cracking of the base, many projects have adopted elastic exterior wall paint, but due to the elastic exterior wall The topcoat has poor air permeability and is prone to blistering and even peeling off of the paint film. Therefore, how to produce a kind of exterior wall paint with high color retention, super durability, self-cleaning, water repellency and good air permeability to replace existing exterior wall paints is a prominent techni...
