Problems solved by technology

[0002] Currently used oil-based paints usually have better performance, but 1) solvent-based paints contain a large amount of volatile organic compounds (VOC), which pollute the environment very seriously, and waste resources and energy; The requirements for matching materials are high, the coating is rigid, does not have good elasticity, and is easy to crack and peel;
[0003] The water-based coatings currently used are convenient for construction, but 1) the appearance of the coating film is poor, and there are many dirty spots, large orange peels, etc.; 2) the performance of general decorative coatings is poor, and it is easy to appear in a short period of time Discoloration; 3) easy to be polluted, poor long-term decoration, poor corrosion resistance
