Description
Technical field
The invention belongs to functional polyester thin film technique field, be specifically related to uvioresistant coating fluid and preparation method and application for a kind of polyester film.
Background technology
In prior art, the anti-ultraviolet function of glass adopts the method for pad pasting or glass coating to solve conventionally, and pad pasting can effectively intercept ultraviolet ray and reach more than 90%.For automotive glass, the people in car, by excessive uviolizing, can accelerate skin aging, skin ambustion, and the facility in car has also been accelerated aging by uviolizing, shortened work-ing life, therefore, is badly in need of the application of high anti-UV pad pasting.
What at present the base material of pad pasting generally adopted is biaxially oriented polyester film, and biaxially oriented polyester film BOPET film has that intensity is high, good rigidly, transparent, glossiness high; Odorless, tasteless, colourless, nontoxic, outstanding obdurability; Its tensile strength is PC film, nylon membrane 3 times, shock strength be BOPP film 3-5 doubly, have fabulous wear resistance, folding resistance, pinhole resistance, tear strength and good static resistance etc.
At present, the problem of the active and poor heat resistance of commercially available BOPET film ubiquity uvioresistant, and along with the more and more high request of people to quality product,, and also more and more receives publicity for the film of high-end field increasing to the demand of polyester film.The general employing of pad pasting manufactured at plastics film surface sputtering metallic membrane and inorganic oxide film, yet the method complicated process of preparation of sputter, need vacuum system and high-tension unit, and sputtering technology need to just can complete under hot conditions, cause equipment and product cost all very high.
Also there is the waterborne polyurethane resin of employing as matrix resin, add therein nano-indium stannum oxide powder, thereby the ink of the uvioresistant infrared resistant making, although the excellent optical performance of this type of ink, but because matrix resin is common waterborne polyurethane resin, the easy yellowing of rete after its film-forming, and tin indium oxide cost is higher, is not suitable for marketing.
Summary of the invention
