The molecular structure of the carbon-fluorine bond contained in the fluorine resin is a known strong molecular bond, with a bond energy as high as 110 kg/mol, and the length of the carbon-fluorine bond is shorter. Therefore, the fluorine resin has far better acid resistance than ordinary resins. , alkali resistance, corrosion resistance, weather resistance and small friction coefficient, hydrophobic, oil repellent, anti-sticking, anti-pollution and other excellent properties. However, it is insoluble in solvents. As a coating, it must be sintered to form a paint film, and its transparency is low. , the adhesion to the base material is poor, the pigment is difficult to disperse, and this method is also difficult to apply during construction. This coating uses fluororesin. By introducing some monomers with functional groups into the main chain of the fluororesin, the resulting copolymer can be soluble in solvents, can be cured at room temperature, and has good aging resistance and salt spray performance. It has passed Technical appraisal by the State Administration of Petroleum and Chemical Industry.
