Problems solved by technology

The coating mainly uses ultraviolet absorbers to improve the weather resistance of the coating. However, the weather resistance of architectural coatings depends on many factors, and UV aging resistance is only one of them. The resulting aging effect cannot be ignored either. The surface of the coating is not ideal in terms of ozone aging resistance and infrared reflection, so the overall weather resistance effect is not good

Abstract

The invention provides a high-weatherability aqueous wall coating. The high-weatherability aqueous wall coating is prepared from, by weight, 30-38 parts of a pure acrylic emulsion, 18-24 parts of a PEVE emulsion, 8-10 parts of CPVC, 4-6 parts of a pigment, 10-16 parts of a filler, 15-21 parts of water, 0.2-0.4 parts of a wetting agent, 0.2-0.5 parts of a dispersant, 2-2.5 parts of a film forming assistant, 0.1-0.6 parts of a thickener, 0.1-0.3 parts of a mildew inhibitor, 0.5-0.6 parts of glycol and 9-14 parts of aluminum doped zinc oxide. The invention also provides a preparation method of the high-weatherability aqueous wall coating. The high-weatherability aqueous wall coating has the advantages of very good ozone ageing resistance, very good infrared reflection performance, and very good weatherability.

Description

Technical field: [0001] The invention relates to a wall paint, in particular to a high weather resistance water-based wall paint and a preparation method thereof. Background technique: [0002] Wall coating refers to the coating used for decoration and protection of building walls, making the building walls beautiful and tidy, and at the same time protecting the building walls and prolonging their service life. According to the classification of building walls, wall coatings include interior wall coatings and exterior wall coatings. Interior wall paint focuses on decoration and environmental protection, while exterior wall paint focuses on protection and durability. In addition to its own decorative and protective functions, wall paint is also developing towards a colorful, fashionable, healthy and environmentally friendly trend. People hope that the decorative effect will be radiant, beautiful, noble, elegant, romantic, and warm; they also hope that the material itself is...
