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

Abstract

The invention discloses an external wall applied water-based low temperature ultraviolet-curing coating, and belongs to the field of coatings, in particular to the field of ultraviolet-curing water-based coatings. The external wall applied water-based low temperature ultraviolet-curing coating consists of the following raw materials: a film-forming substance, a solvent, talcum powder, a dispersant, a leveling agent, a photoinitiator and white carbon black. The cured product of the fluorine-containing coating is good in performance, and samples obtained after curing are excellent in adhesion, scratch resistance and stain resistance.

Description

Technical field [0001] The invention belongs to the field of coatings, in particular to the field of water-based coatings cured by ultraviolet light. 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 inherent disadvantages of water-based paints such as low hardness, high energy consumption, and high requirements for the cleanliness of the construction process and the surface of the material; it solves the problems of unsafe light-curing solvent coatings and curing shrinkage, and realizes water-based environmental protection. Low cost and high efficiency application. With the further development of the research on light-curing hydrophilic coatings, the application range of light-curing hydrophilic coatings is becoming more and more extensive. It can be coated on metal, wood, plastic, leather, glass,...
