Description
Technical field
The invention belongs to paint field, particularly to a kind of ultraviolet light polymerization fluorine carbon solar battery
Back-protective coating.
Background technology
In recent years, due to environmental pollution and petroleum-based energy exhaustion two large problems, solaode is made
For a kind of renewable and clean energy resource increasingly by consumers.Solaode is typically by such as
Lower structure forms: front is the glass substrate of light, is sandwiched between multiple plate-shaped solar battery
Element, the back side is then protecting film.Solaode disclosure satisfy that in outdoor application decades
Electrical equipment, and back protection film is exposed in atmosphere, stands long-term rain drop erosion and the sun
Irradiation, thus back protection film must possess certain weatherability, abrasion resistance, moisture resistance and
Thermostability.But, single protecting film is difficult to be provided simultaneously with these functions, therefore need be at the back of the body
A kind of coating with above-mentioned functions of application on surface protective film.
The most mostly use traditional coating as the sealer of back protection film, example
Such as patent documentation 1(CN101805578A) disclose a kind of polyester coating, by hydroxyl
Polyester resin and hexamethylene diisocyanate trimer carry out chemical reaction of becoming film；Patent documentation 2(is special
