Problems solved by technology

[0003] FEVE fluorocarbon coating: ①Formulation: processed by fluorine-modified polymer resin, pigments, additives, solvents, etc. ②Process: Base treatment→spraying the first layer of primer→surface drying→spraying the second layer of primer→spraying topcoat→ High-temperature sintering (430°C) → finished product; ③ Existing problems: a. Not environmentally friendly: the water is highly polluted, the gas emitted is difficult to handle, and it is harmful to the human body. The hidden chemicals can cause harm to the human body after 30 years; b. Unsafe: thick smoke will be generated when encountering an open flame, which will cause great harm to the human body; c. Not energy-saving: the sintering temperature should be above 420°C, 30 minutes); d. Complicated processing: three layers of spraying, high loss rate; d. Hardness Low
[0004] Enamel (enamel): ①Formulation: quartz, silicate, potassium feldspar, kaolin; borax, sodium nitrate, soda ash, lithium carbonate, calcium carbonate, magnesium oxide, zinc oxide, titanium dioxide, antimony oxide, zirconium dioxide, cobalt oxide , nickel oxide, manganese dioxide, iron oxide, etc.; ②Process: glaze preparation→body preparation→enamelling→sintering (850℃)→firing→inspection, etc.; ③Existing problems: a. Difficult processing: processing technology Complicated, with many processes; b. Not environmentally friendly and energy-saving: high temperature sintering is required (850 ° C, more than 30 minutes); c. Fragile and poor flexibility

Description

Technical field [0001] The invention relates to a coating formulation and a method for coating building material substrates using the formulation. Background technique [0002] Metal materials have the properties of light weight, high strength, and good fire resistance, and are widely used in modern buildings. As metal materials come into contact with air or water vapor in the air, they are easy to oxidize and rust, and are not resistant to acids and alkalis. Therefore, when used in building materials, they will be coated with anti-oxidation coatings on the metal substrate. Most of the existing technologies use FEVE Fluorocarbon paint or enamel: [0003] FEVE fluorocarbon coating: ①Formulation: fluorine-modified polymer resin, pigments, additives, solvents, etc. ②Process: basic treatment→spray the first layer of primer→surface drying→spray the second layer of primer→spray topcoat→ High temperature sintering (430℃)→finished product; ③Problems: a. Not environmentally friendly: the ...
