Abstract

The invention belongs to the technical field of liquid fluorine coatings for photovoltaic packaging adhesive films, and particularly relates to an electron beam cured weather-resistant fluorine coating, a weather-resistant fluorine coat, a photovoltaic packaging adhesive film and a preparation method thereof. The weather-resistant fluorine coating comprises the following raw materials in parts byweight: 40 to 65 parts of matrix resin, 20 to 50 parts of a pigment filler, 10 to 20 parts of an active diluent, 2 to 6 parts of a conventional auxiliary agent, 1 to 4 parts of a rheological additive,and 0.5 to 3 parts of down-conversion nano powder. Fluororesin and an ultraviolet conversion material are used, so that the weather fastness and durability of the coating can be effectively guaranteed; and meanwhile, by improving the rheological property and the crosslinking property of the weather-resistant coating, the coating is fully infiltrated on the surface of the adhesive film and forms effective chemical bond bonding through curtain-shaped electron beam radiation, and the weather-resistant coating is suitable for being used for printing in a grid region of the photovoltaic packagingadhesive film. According to the weather-resistant fluorine coat formed after electron beam cross-linking curing and corona treatment, the coat and an adhesive film matrix are not prone to layering, and the weather-resistant fluorine coat has the advantages of being uniform in thickness, good in adhesive force, excellent in aging performance and the like.

Description

technical field [0001] The invention belongs to the technical field of liquid fluorine coatings for photovoltaic encapsulation adhesive films, and in particular relates to an electron beam-cured weather-resistant fluorine coating, a weather-resistant fluorine coating, a photovoltaic adhesive film and a preparation method thereof.
