Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, technical solution of the present invention is described in further detail, can better understand the present invention to make those skilled in the art and can be implemented, but illustrated embodiment is not as a limitation of the invention.
A preparation method for peep-proof film, its concrete preparation process is as follows:
S01: it is resin-coated shaping to carry out UV on pet layer 1, for the ease of distinguishing, by this UV resin called after first transparent resin, obtained the first transparent resin layer 2 of covering on pet layer 1 and some row are evenly distributed on the protrusion unit 3 on the first transparent resin layer 2, as shown in Figure 1, wherein protrusion unit 3 can be cuboid, prism, also can be as shown in Figure 1, the cross section of protrusion unit 3 is trapezoidal, and upper base is less than and goes to the bottom, and this kind shape manufacturing process is easier, result of use is also best, to be follow-uply all described in detail with this kind of structure.Be evenly spaced between protrusion unit 3, after step S01, form gap 4 between two between protrusion unit 3, the cross section in gap 4 is trapezoidal, and upper base is greater than and goes to the bottom.
S02: wet black or grey filler in the space between protrusion unit 3, the mixture of such as nano ink, epoxy resin or acrylic resin and solvent and carbon black/titanium dioxide/White Carbon black, as shown in Figure 2, gap 4 becomes opaque filler cells 5.Structure due to peep-proof film is very meticulous small, and therefore black or grey filler can form one deck thin layer in the outermost of peep-proof film, i.e. superficial layer 6.Wet is a kind of by the base material of rolling, as: paper, cloth, leather, aluminium foil, plastic sheeting etc., be coated with the glue of the solvent-laden specific function of last layer, coating or ink etc., and the technique of rolling after drying removal solvent.
S03: remove superficial layer 6, wipe the structure after superficial layer 6 as shown in Figure 3.
S04: baking: allow the solvent in filler vapor away, the solid constituent in filler is deposited on the bottom in space, the opaque integument of space side attachment one deck.Baking can discharge black between protrusion unit 3 or grey filler, now black or grey filler are liquid states, after discharging black or grey filler, only remain black or grey filler with the contact surface of protrusion unit 3, its structure as shown in Figure 4, solvent volatilizees, opaque bottom 7 is formed on the bottom in the space that black or grey filler are deposited between protrusion unit 3, and the thin layer of black or grey filler formation is also adhered in the side in space, i.e. opaque integument 71, the scope of its thickness is depending on the colourity of the color of added filler, the more black thickness of color is thinner, scope can be lower than 5 microns.The top in space or opaque bottom 7 be cavity 8 above.
