Abstract

The invention belongs to the technical field of photovoltaic module printing, and particularly relates to a method for improving weather resistance of a color layer on the surface of a photovoltaic module. Spraying the photovoltaic module by using an ink spray head and a transparent gloss oil spray head at the same time; and after the color and the gloss oil are simultaneously jetted on the surface of the photovoltaic module, performing ultraviolet curing on the surface of the photovoltaic module. The invention is suitable for the printing process of a color photovoltaic module, particularly suitable for the printing process of a color building photovoltaic integrated module, reduces the spraying frequency and curing frequency by simultaneously spraying color and transparent gloss oil, avoids the use of coating liquid, greatly reduces the time and economic cost of the printing process of the photovoltaic module, and improves the printing efficiency. And the working efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic assembly printing, and particularly relates to a method for improving the weather resistance of a color layer on the surface of a photovoltaic assembly. Background technique [0002] With the continuous development of photovoltaic technology, building photovoltaic integration has also become a clear development trend. Different from large-scale photovoltaic power generation equipment usually set in no-man's land, building photovoltaic integrated products usually require bright colors, and must be To ensure that the color will not fade for a long time in the wind and rain environment. At present, the most commonly used technology for color printing of photovoltaic modules is UV ink printing. UV printing is a printing process that dries and cures ink by ultraviolet light. The photosensitizer ink is matched with UV curing lamp. The application of UV printing is one of the most important content...
