And the substrate of photographic film etc., it is also applied to the electricity such as electrical insulating material, capacitor films, flexible printed circuit board and thin film switch
Subdomains and machinery field.But poly-vinegar temperature tolerance is poor.In the higher situation of operating temperature, poly-vinegar film will appear mechanics
The phenomenon that performance decline, overall shrinkage, to affect the range and safety that it is used.On the other hand, outdoor long-time service
Requirement of the poly-vinegar membrane product for ultraviolet light stability and hydrolytic resistance it is higher and higher.And GW-770, GW-622, GW-540 are deposited
The facile hydrolysis the problem of, its photostability is lost under the influence of rainwater faster outdoors.GW-622 belongs to polymerized hindered
Amine light stabilizer, but molecular weight is less than 4000 and susceptible to hydrolysis.At present, solar cell backboard is commonly used two-way
Stretching poly-vinegar film is substrate, and surface coats fluoropolymer or carries out with fluoro-containing copolymer film compound to improve backboard in length
Weatherability in phase use process.Wherein, uvioresistant performance is one of key index of weatherability.Fluoropolymer can assign
The excellent weatherability of solar energy backboard, but due to prices of raw materials height, and processing and forming is relatively difficult, makes fluorine-containing solar-electricity
Pond backboard cost is high.Thus provide that a kind of high temperature resistance is good and the demand of ultraviolet light stability is more more and more intense.
