Description
Technical Field
The utility model relates to a plastic film technical field, concretely relates to selfreparing protection film.
Background
The plastic film has low wear resistance and surface hardness, and the surface of the film is easy to scratch after long-term use to influence the performances of optical transparency, decoration and the like. In order to solve the problem of poor wear resistance of the plastic film, the surface of the plastic film is mainly hardened at the present stage, and a hardened layer is mainly coated by a wet method.
The general hardening treatment of the surface of the plastic film is helpful for reducing the degree of scratching of the surface and prolonging the service life, but the surface cannot be reversibly restored or repaired once the surface is contacted with a sharp object or the scratch caused by friction is generated. Therefore, the design of coating the self-repairing layer on the plastic film carrier layer can further prolong the service life of the material and endow the material with special functional applicability.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a self-repairing membrane that physical properties and chemical properties are good to the weak point among the prior art.
To achieve the purpose, the utility model adopts the following technical proposal:
a self-repairing protective film comprises a high-transmittance polyester film, a polyurethane curing self-repairing coating and a hardened polyester film; the high-transmittance polyester film, the polyurethane curing self-repairing coating and the hardened polyester film are sequentially laminated and compounded; the inner side of the high-transparency polyester film is provided with a concave-convex surface, and the concave-convex surface is uniformly filled with the polyurethane curing self-repairing coating.
In a further aspect, the uneven surface is formed by dot-shaped raised particles or diagonal raised particles.
More specifically, the thickness of the high-permeability polyester film is 95-105 μm.
In a further aspect, the polyurethane cured self-healing coating has a thickness of 25 to 35 μm.
More specifically, the thickness of the hardened polyester film is 35 to 45 μm.
The utility model has the advantages that: the utility model discloses a selfreparing protection film, the light transmissivity is good, and the outward appearance is good, has fine anti nail fish tail nature, and little mar self-repairing nature. The utility model discloses mainly used cell-phone protective housing, the non-rubber coating face pressfitting of polyester film is passed through to the height tears the polyester film that hardens outside the cell-phone protective housing for the cell-phone protective housing has the function of selfreparing, can resist the nail fish tail, and the selfreparing of mar a little.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic overall structure diagram of an embodiment of the present invention;
wherein: the high-transmittance polyester film 1, the polyurethane curing self-repairing coating 2 and the hardened polyester film 3.
Detailed Description
The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.
As shown in fig. 1, the self-repairing protective film comprises a high-transmittance polyester film 1, a polyurethane curing self-repairing coating 2 and a hardened polyester film 3; the high-transmittance polyester film 1, the polyurethane curing self-repairing coating 2 and the hardened polyester film 3 are sequentially laminated and compounded; the inner side of the high-transparency polyester film 1 is provided with a concave-convex surface, and the concave-convex surface is uniformly filled with the polyurethane curing self-repairing coating 2.
The high-transparency polyester film 1 is used as a substrate, and has excellent optical properties such as good transparency, low haze and high glossiness besides the excellent physical and mechanical properties of the common polyester film. The material is used as a base material, so that the light transmittance of a finished product can be improved, and the appearance is better. The polyurethane curing self-repairing coating 2 is a UV curing self-repairing coating, and a cured coating film has good fingernail scratch resistance and micro scratch self-repairing property. The paint film has particularly good flexibility and bending resistance, and the scratch resistance of the surface of the film material can be greatly improved by coating the high-transparency polyester film surface 1. The hardened polyester film 3 is used as the back film composite adhesive surface, so that the adhesive surface is smoother without foaming, and the adhesive surface is better protected before use by customers. The inner side of the high-transparency polyester film 1 is provided with a concave-convex surface, so that the polyurethane curing and self-repairing coating 2 can be coated more conveniently, the combination of the two is tighter, and the self-repairing characteristic of the polyurethane curing and self-repairing coating 2 is fully exerted.
In a further aspect, the uneven surface is formed by dot-shaped raised particles or diagonal raised particles.
The concave-convex surface formed by the point-shaped convex particles or the twill can form uniform concave for coating the polyurethane curing self-repairing coating, and simultaneously, the performance of the high-transparency polyester film can not be influenced.
More specifically, the thickness of the high-permeability polyester film is 95-105 μm.
The high-transparency polyester film with the thickness of less than 95-105 μm cannot provide enough physical and mechanical bearing capacity, and the high-transparency polyester film with the thickness of more than 95-105 μm influences the overall thickness of the self-repairing protective film, so that the cost is increased.
In a further aspect, the polyurethane cured self-healing coating has a thickness of 25 to 35 μm.
The polyurethane curing self-repairing coating needs to fully cover the high-transparency polyester film, the polyurethane curing self-repairing coating with too low thickness is difficult to cover the concave-convex surface of the high-transparency polyester film, and the polyurethane curing self-repairing coating with too high thickness affects the cost.
More specifically, the thickness of the hardened polyester film is 35 to 45 μm.
The utility model discloses a selfreparing protection film mainly used cell-phone protective housing is outside the cell-phone protective housing to the non-rubber coating face pressfitting of high polyester film that passes through during the use, tears the polyester film that hardens for the cell-phone protective housing has the function of selfreparing, can resist the nail fish tail, little mar selfreparing. The hardened polyester film is mainly used for protecting the self-repairing protective film before use and is discarded after use, so that the thickness of the hardened polyester film is set to be 35-45 mu m in consideration of both the protection effect and the cost.
The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the description should not be construed as a limitation to the present invention.
