Background technology
High transparent liquid crystal screen protecting film is the complex optics plated film coating that is formed by the transparent pad pasting three laminated that superpower anti-scratch damage is processed; middle main lipid material matter is biaxially oriented polyester film PET ethylene glycol terephthalate; the top layer is low-density polyester resin layer, and bottom is the compound silica gel material.The basic principle of high transparent antifouling liquid crystal screen protection paste is also basic identical with high transparent liquid crystal diaphragm; but its difference is the top layer UV curing polyester resin that its middle main lipid material matter is biaxially oriented polyester film PET and adds an amount of Organic fluoride formation, therefore has more oil-stain-preventing and the characteristic that comprises fingerprint than general high transparent liquid crystal diaphragm.
Although common high transparent liquid crystal diaphragm has good anti-scratch effect on the market; but the poor performance of its oil-stain-preventing and fingerprint; although and high transparent its antifouling property of antifouling liquid crystal protective film is strong; but because its raw material Organic fluoride expensive, so the cost of raw material exceeds more than 5 times of common high transparent liquid crystal diaphragm.
In order to solve the problem that exists in the above technology, the present invention has made following technical solution.
Summary of the invention:
Such as Fig. 1, the present invention is comprised of PET protection stripping film 1, PET low viscosity diaphragm 2, PET stripping film 3.
Such as Fig. 2, described PET low viscosity diaphragm 2 is comprised of the anti-scraping coating 21 of UV, the low sticking protective film 22 of PET and silica-gel coating 23.Being PET protection stripping film 1 on PET low viscosity diaphragm 2, is PET stripping film 3 below it.
Such as Fig. 2, the anti-scraping coating 21 of UV is comprised of the transparent UV coating 211 of height and common UV coating layer 212, and its feature is as follows:
1, first at the mylar of polyester film pet sheet layer coating 3-4 micron, carries out behind the compo with the mylar that is coated with again the 1-3 micron behind the UV photocuring and Organic fluoride solidifying the second time.
2, its gross thickness is 4 microns-7 microns after twice coating.
3, full light light transmittance reaches more than 91%.
4, the oil-stain-preventing effect is for streaking 10 times without the printing ink vestiges with the oil pen at same place.
5, ground floor mylar and PET's is then good, and hundred lattice test I SO standards occur without degumming phenomenon more than 1 grade or 1 grade.
6, the second layer has good adhesion by coating layer and the ground floor mylar that the coating of the compo of mylar and Organic fluoride forms, and 1 grade of iso standard of hundred lattice test I SO standards occurs without degumming phenomenon more than 1 grade or 1 grade.
7, case hardness is 2H-5H.
8, bottom is the compound silica gel material, and its thickness is 10 microns to 50 microns.
The invention has the beneficial effects as follows the change manufacture technology, change twice UV coating into by UV coating, and keep high transmission rate and anti-scratch colored effect constant.Manufacture engineering although increased, can reduce the cost of raw of 30%-70%, can descend more than 50% thereby make product manufacture cost.
The specific embodiment:
Such as Fig. 1, the present invention is comprised of PET protection stripping film 1, PET low viscosity diaphragm 2, PET stripping film 3.
Such as Fig. 2, described PET low viscosity diaphragm 2 is comprised of the anti-scraping coating 21 of UV, the low sticking protective film 22 of PET and silica-gel coating 23, is PET protection stripping film 1 above it, is PET stripping film 3 below it.
Such as Fig. 3, the anti-scraping coating 21 of UV is comprised of the transparent UV coating 211 of height and common UV coating 212, at the mylar of polyester film pet sheet layer coating 3-4 micron, carry out behind the compo with the mylar that is coated with again the 1-3 micron behind the UV photocuring and Organic fluoride solidifying the second time first.
