Problems solved by technology

[0003] At present, the mainstream solution for the protective layer of solar backplanes is transparent fluorine film, that is, transparent PVDF, but the transparent fluorine film depends on imports. Compared with imported transparent fluorine films, domestic transparent fluorine films have lower light transmittance and insufficient weather resistance. , directly lead to higher price of imported transparent fluorine film

Abstract

The invention belongs to the technical field of protective films, and particularly relates to a solar backboard protective film and a preparation process thereof.The solar backboard protective film comprises a base layer, the surface of the base layer is coated with a composition protective layer, and the base layer comprises one of PET or PUE; wherein the composition protective layer is composed of the following material components: 10-30 parts of polyurethane acrylate; 10 to 30 parts of epoxy acrylate; 10 to 30 parts of polyester acrylate; 10 to 30 parts of polyacrylate; an antioxidant: 0.01 to 0.5 part of BASF; 0.01 to 0.1 part of an ultraviolet light absorber; 0.01 to 0.1 part of a light stabilizer; 0.01 to 0.1 part of a leveling agent; and 0.01 to 0.1 part of a defoaming agent; and poor weather resistance caused by residual double bonds can be avoided, the double bond conversion rate of electron beams is higher from performance comparison, and better hardness, wear resistance and chemical resistance are achieved.

Description

technical field [0001] The invention belongs to the technical field of protective films, and in particular relates to a solar back panel protective film and a preparation process thereof. Background technique [0002] At present, the car window film and architectural window film are all based on PET, and a layer of UV light-cured protective layer is coated on the surface. Since it is UV-cured, the amount of ultraviolet light absorber added directly affects the curing degree of the protective layer. And performance, resulting in the aging resistance of automotive window films and architectural window films has always been a pain point in the industry. [0003] At present, the mainstream solution for the protective layer of solar backplanes is transparent fluorine film, that is, transparent PVDF, but the transparent fluorine film depends on imports. Compared with imported transparent fluorine films, domestic transparent fluorine films have lower light transmittance and insuffi...
