Abstract

The invention provides a weather-resistant ultraviolet curing ink and a preparation method thereof, and the weather-resistant ultraviolet curing ink is composed of 28-35 parts of urethane acrylate, 40-45 parts of an LED reactive diluent, 10-18 parts of styrene-maleic anhydride copolymer resin, 5-10 parts of a photoinitiator, 1-3 parts of an auxiliary agent and 3-4 parts of a filler. The polyurethane acrylate and the styrene-maleic anhydride copolymer resin are blended to serve as a prepolymer, urethane bonds on the polyurethane acrylate and high-activity maleic anhydride groups on the styrene-maleic anhydride copolymer resin are subjected to a chemical reaction to form firmly-combined covalent bonds, and interface combination of the ink is improved; therefore, the tensile property, the bending property, the toughness and other mechanical properties of the material are improved, the water resistance, the heat resistance and the adhesive force to a polar base material of a film layer can be obviously improved, high gloss is kept, and the weather resistance is very high when the material is applied to outdoor advertising ink.

Description

technical field [0001] The invention belongs to the technical field of UV-LED inks, and in particular relates to a weather-resistant ultraviolet light curing ink and a preparation method thereof. Background technique [0002] Outdoor advertising is one of the main publicity channels. Outdoor advertising will be damaged by harmful factors such as ultraviolet rays, acid and alkali, sand and air for a long time. Therefore, the weather resistance of outdoor inks used for printing outdoor advertising is very important. The four-color dot ink used in the traditional advertising industry is solvent-based, and each color of printing must be dried before another color can be overprinted. The drying is slow and the working hours are long, resulting in low production efficiency; on the other hand, the solvent-based ink printing process A large amount of volatile compounds are released into the air, causing air pollution in the printing workshop and seriously affecting the health of wor...
