Abstract

The invention discloses acrylic resin paint capable of being quickly cured. The paint is a double-component curing system. Modified acrylic resin and alpha-(methyl)alkyl cyanoacrylate have good intersolubility and good adhesion, alpha-(methyl)alkyl cyanoacrylate can accelerate curing of a coating. The paint system can be quickly cured, and the environment-friendly coating which is good in weather resistance and high in adhesion can be obtained. The technology is simple, operation is easy, coating efficiency can be improved, and the good paint can be used for solar cell backplanes.

Description

technical field [0001] The invention relates to a fast-curable acrylic resin paint, which belongs to the technical field of material surface protection. Background technique [0002] Solar cell modules in photovoltaic power generation must meet the requirements of outdoor use for more than 25 years. The backsheet is located on the outermost layer of photovoltaic cell components to protect and support the cells. It must have reliable electrical insulation, moisture resistance and good weather resistance. [0003] At present, fluorine-containing polymer backsheets are mostly used in the manufacture of photovoltaic modules in my country. One is a glue-coated composite backsheet, which is composed of fluorine film or EVA film on both sides of PET and other polyester films. It has a three-layer structure, and the common ones are TPT and TPE. , KPK and other structures. This type of backsheet needs to be coated with an adhesive between the fluorine-containing film and PET and ado...
