Example Embodiment
[0036] Example 1
[0037] The structure diagram of the nano anti-glare, anti-fingerprint and anti-peeping screen protective film of this embodiment is as follows figure 2 As shown, the nano anti-glare, anti-fingerprint and anti-peeping screen protective film is attached to the glass screen 11, which includes a silicone layer 10, a polarized anti-peep film layer 9, an adhesive layer 8, and a PET film layer from the inside to the outside. 7 and anti-glare anti-fingerprint nano coating 6. The preparation is as follows:
[0038] Step 1: Prepare a polarized anti-peep film layer 9 on the organic silica gel layer 10;
[0039] The structure and preparation method of the polarized anti-peep film image 3 As shown, the details are as follows:
[0040] 1) Coat a layer of photoresist 13 (polyvinyl laurate) on the organic silica gel layer 10, and control the thickness of the coating to 200-1500 microns; then irradiate the coating with ultraviolet light through the grating 12, The pitch of the ...
Example Embodiment
[0047] Example 2
[0048] This embodiment is the same as embodiment 1, the difference lies in:
[0049] In step 1), the photoresist is epoxy-based ultraviolet negative photoresist; the thickness of the photoresist coating is 200 microns; the pitch of the grating 12 is 100 microns; in step 2), ethyl acetate is used to dissolve the Cross-linked photoresist; in step 1 3), fill the cavities with opaque titanium dioxide; pre-disperse ultra-fine titanium dioxide in a room temperature curable low-viscosity resin (a combination of glycidyl ester epoxy resin and fatty amine) Mixed)
[0050] Step 3. The fluorosilicone polymer is polydimethylsiloxane-b-polyheptafluorobutyl methacrylate; adding 2.5% by weight to the total weight of the fluorosilicone polymer and a particle size of 700 nanometers of dioxide Silicon: The thickness of the anti-glare and anti-fingerprint nano coating is 0.2 microns.
Example Embodiment
[0051] Example 3
[0052] This embodiment is the same as embodiment 1, the difference lies in:
[0053] In step 1), the photoresist is cyclized polyisoprene-bisazide ultraviolet photoresist; the thickness of the photoresist coating is 500 microns; the pitch of the grating 12 is 250 microns; in step 3) , Fill the cavities with opaque pigment particles; pre-disperse the opaque pigment particles in a low-viscosity resin curable at room temperature (the polycondensation of phthalic anhydride and propylene glycol is a linear high resin with ester bonds and unsaturated double bonds). Molecular compound);
[0054] Step 3. The fluorosilicone polymer is a blend of polytrifluoropropylmethyl cyclotrisiloxane and polytrifluoropropylmethyldichlorosilane; the content of the weight percentage of the total weight of the fluorosilicone polymer is 5 %, silica with a particle size of 1000 nanometers; the prepared anti-glare and anti-fingerprint nano coating has a thickness of 3.0 microns.
