Abstract

The invention discloses an anti-fading coating. The anti-fading coating comprises the following raw materials by weight: 30-50 parts of waterborne emulsion, 35-50 parts of alcohol solvent, 5-10 partsof sodium gualenate, 4-8 parts of nanometer-sized neodymium oxide, 2-5 parts of cationic poly-alkylamine dye fixing agent, 2-5 parts of filter mud, 1-3 parts of nanometer silicon nitride, 2-4 parts ofpowdered borax, 1-3 parts of nano-zinc oxide, 1-5 parts of zeolite powder, 2-6 parts of nickel powder, 1-2 parts of coalescing agent, and 2-5 parts of boehmite powder. The coating is excellent in adhesive force, impact resistance, acid-base resistance property, ageing resistance, curing rate, water resisting property and ultraviolet radiation resistance property; the coating does not crack or fade easily, the color lasts for long, and meanwhile, the preparation method is simple, and is higher in economic value and market value.

Description

technical field [0001] The invention relates to an architectural coating, in particular to an anti-fading coating and a preparation method thereof. Background technique [0002] Paint is a material that can be well bonded to the base material and form a complete and tough protective film on the surface of an object, called a paint. Paint and paint are the same concept. Paint is a customary name that people have used for a long time. After it was introduced into my country, it has been used in the construction industry. The role of coatings can be summarized into three aspects: protection, decoration, and special functions. [0003] Architectural coatings can protect the exterior walls of buildings that have been exposed to wind, sun, and rain for years. They must have good enough water resistance, weather resistance, stain resistance, and freeze-thaw resistance to ensure good performance. Decorative effect and durability. However, existing coatings still have shortcoming...
