A kind of high transparency polyether-type bimirror face TPU film

The invention belongs to field of material technology, and in particular to a kind of high transparency polyether-type bimirror face TPU film and preparation method thereof.The TPU film, raw material by weight, including following components；TPU resins：100 parts；Antioxidant：0.1 ~ 0.8 part；Light stabilizer：0.1 ~ 1.8 part；Lubricant：0.01 ~ 0.05 part.Its preparation method comprises the following steps：Each component raw material according to formula consumption is put into stirrer for mixing uniform, be then pumped into dehumidifying heat pump drying, then high transmittance film polyether film product is obtained to pressure, cooling, shear, winding of pressurizeing by extrusion curtain coating, minute surface.The high transparency polyether-type bimirror face TPU film prepared by the present invention, overcomes poor transparency, and plasticizing is uneven, is also easy to produce fisheye, the critical technological point of easy roll banding, production capacity is improved, uniform with thickness, and the high grade of transparency, surface gloss is high, the characteristic such as color inhibition.
