Because of the powerful functions, the plastic film is widely applied to industry products such as plastic products, decorative plates, electronic components, electric appliance circuit screen display equipment and the like at present, and the common product application is as follows: the surface protection of high-grade materials such as plastic lenses, liquid crystal displays, aluminum sheets, stainless steel plates, cold-rolled plates, circuit boards, loudspeaker boxes, PC panels, titanium plates and the like avoids the damage of the product surface due to collision and the influence of grinding and rubbing on the normal use of the product or the selling point in the transportation or production and manufacture and terminal use processes.

However, the surface adhesion of the existing blue protective film is poor, the surface of the existing blue protective film is not easy to be printed by ink or coated by functional coating, and the appearance and the function of the product are influenced by the falling off of the surface printing layer or the coating.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome above-mentioned prior art's defect, provide a blue protection film of the high adhesion of multi-functional type BOPP, can effectively provide the surface of blue protection film to the adhesive force of printing layer or coating, make the protection film surface easily by the printing or paint the functional layer to the printing layer or the coating of formation are difficult for droing.

In order to realize the purpose, the utility model provides a technical scheme does: the provided multifunctional BOPP high-adhesion blue protective film comprises a first blue polypropylene film layer, a material core supporting layer, a second blue polypropylene film layer and a high-adhesion function realizing layer from bottom to top, wherein the high-adhesion function realizing layer is prepared from a modified high-adhesion material, a fine and ordered concave-convex structure layer is further arranged on the surface of the high-adhesion function realizing layer, the concave-convex structure layer is composed of uniformly distributed silica particles adhered to the high-adhesion function realizing layer, and the particle size of the silica particles is 5-8 mu m.

Preferably, the high adhesion function realization layer is composed of a copolymer of acrylates and vinyl acetate.

Preferably, the first blue polypropylene film layer and the second blue polypropylene film layer are both made of modified polypropylene.

Preferably, the first blue polypropylene film layer and the second blue polypropylene film layer further contain a blue color masterbatch.

Preferably, the core support layer of the material is comprised of a film grade proprietary polypropylene.

Preferably, the surface roughness of the textured layer is 0.6 to 1.0 μm.

Preferably, the thickness of the first blue polypropylene film layer is 1-3 μm, the thickness of the core support layer in the material is in the range of 30-50 μm, the thickness of the second blue polypropylene film layer is 2-5 μm, and the thickness of the high adhesion function realization layer is 1-3 μm.

The utility model has the advantages that: (1) the adhesive force of the surface of the protective film to the printing layer or the coating can be effectively improved, so that the surface of the protective film is easier to print, paint or compound other functional layers, and the printing layer or the coating is not easy to fall off. Lead to through being provided with the concave-convex structure layer that silica particle constitutes, except guaranteeing that the due opening nature of protection film prevents the rolling adhesion, can effectively improve the roughness on film surface, the concave-convex constitutional mode that leads to of this silica particle is favorable to increasing the effective area of contact with printing ink or functional coating to improve the adhesion function and realize the adhesive force of layer to printing or other functional coatings. (2) The copolymer of the acrylate and the vinyl acetate has high adhesion, and the adhesion of the surface of the material to a printing layer or a coating can be improved by combining the copolymer with a concave-convex structure layer formed by the silica particles. (3) The material middle core supporting layer is made of special polypropylene of film grade, has good stability, good fluidity and high film forming rate, has excellent binding force with a surface blue polypropylene film layer, and is not layered or peeled.
