Problems solved by technology

However, most exterior 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 The wall and wall paint has poor air permeability, and it is prone to blistering and even peeling off of the paint film

Abstract

The invention relates to a nanometer silicon wall paint for an external wall, which is prepared by using the following raw materials by weight part: 20-40 parts of de-ionized water, 0.5-0.8 parts of dispersing agents, 0.1-0.3 parts of wetting agents, 0.1-0.3 parts of bactericides, 1-3 parts of anti-freezing agents, 0.1-0.2 parts of pH regulators, 0.2-0.4 parts of de-foaming agents, 15-25 parts of pigments, 15-25 parts of fillers, 5-8 parts of nanometer calcium carbonate, 0.2-0.4 parts of mildew preventives, 0.3-1.0 parts of thickening agents, 15-35 parts of silicone acrylic emulsions, 3-5 parts of organic silicon modified acrylic ester polymerized emulsions and 0.5-1.0 parts of film-forming auxiliaries. The nanometer silicon wall paint for the external wall has a hydrophobic self-cleaning effect and has super climate resistance.

Description

technical field [0001] The invention relates to a nano silicon exterior wall paint. Background technique [0002] At present, exterior wall paint is a kind of protective and decorative water-based paint applied to the exterior walls of buildings such as houses, apartments, hotels, etc. It has a wide range of applications, is convenient to use, is non-toxic, and is environmentally friendly. However, most exterior 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 and wall paint has poor air permeability, and it is prone to blistering and even peeling off of the paint film. [0003] 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...
