Problems solved by technology

Although fluorine materials have the above advantages, the difficulty of processing has always been a difficulty that plagues the promotion of fluorine materials. For example, tetrafluoro compounds are insoluble in conventional solvents. As coatings, they must be sintered to form thin polymers. This method is used in construction. Difficult to popularize and apply in
In addition, the excellent heat resistance, weather resistance and chemical medium resistance of fluorine materials are closely related to their fluorine content, but the fluorine coatings used today generally have low fluorine content

Description

technical field [0001] The invention belongs to the field of coatings, in particular to the field of UV-cured water-based coatings. Background technique [0002] Light-curing water-based coatings combine the advantages of water-based coatings and light-curing solvent coatings, and have developed rapidly in recent years. Light-curing water-based coatings solve the shortcomings of water-based coatings such as inherent low hardness, high energy consumption, and high requirements for cleanliness in the construction process and material surfaces; solve the problems of unsafe light-curing solvent coatings, curing shrinkage, etc., and realize water-based environmental protection. Low cost and high efficiency application. With the further development of research on photocurable hydrophilic coatings, the application range of photocurable hydrophilic coatings is becoming wider and wider, and can be coated on metals, wood, plastics, leather, glass, ceramics and other substrates, so th...
