Summary of the invention
To overcome crystal film surface in the prior art easily to be scratched, the problem of injured surface structure, proposing one kind has
Super permeable epitaxial of scratch resistant function and preparation method thereof, including hardened layer, acrylic, polyester film, polyurethane and EVA resin,
So being coated with acrylic on the outside of polyester film, the hardened layer is attached on the mylar for being coated with acrylic, and polyester
Polyurethane is coated on the inside of film, the mylar is compounded with one layer of EVA resin by polyurethane, and the hardened layer is plating anti-scratch
Hurt film, and the inside of hardened layer is equipped with thermal insulation layer, is coated with nanometer on four peripheral walls of the super permeable epitaxial for having scratch resistant function
Zinc oxide, hygroscopic agent is added in the EVA resin mixing, and hygroscopic agent is evenly distributed on the bottom of EVA resin.
Preferably, the hardened layer is clear hard coating, clear hard coating is using phosphocreatine as raw material
Solidfied material, and clear hard coating is solidified using UV, and the thickness range of clear hard coating is between 0.01-0.05 μm.
By using above-mentioned technical proposal, clear hard coating uses epoxy resin to carry out what UV was solidified to form for raw material
The features such as thin slice of hard has closely knit, water resistant, anti-leakage good, and intensity is high, the cementation zone as crystal film have good
Attribute, while light transmittance with higher.
Preferably, the hardened layer, using plating anti-scratch film, the plating anti-scratch film passes through nanometer by fluoro-containing coating
Technology film made of substrate surface, the fluoro-containing coating are 17 fluorine certain herbaceous plants with big flowers ethyl triethoxy silicane alkane.
By using above-mentioned technical proposal, coating, coating tool are carried out using containing 17 fluorine certain herbaceous plants with big flowers ethyl triethoxy silicane alkane
There is water proof anti-soil, insulate the functions such as acidproof, wear-resisting scratch-resisting trace, the superior performances such as adhesive force, the thin property of film forming and light transmittance.
