Abstract
The utility model relates to the technical field of PVD (physical vapor deposition) coating, and discloses a PVD (physical vapor deposition) anti-overflow plating high-temperature-resistant protective film, which comprises a PET (polyethylene terephthalate) substrate layer and a special coating, wherein the special coating is uniformly coated on the lower surface of the PET substrate layer, and is matched with the PET substrate layer for use.
Description
Technical Field
The utility model relates to the technical field of PVD coating, in particular to a PVD anti-overflow plating high-temperature resistant protective film.
Background
PVD refers to a process of transferring substances by a physical process and transferring atoms or molecules from a source to the surface of a base material, and has the function of spraying certain particles with special properties (high strength, wear resistance, heat dissipation, corrosion resistance and the like) on a matrix with lower properties, so that the matrix has better properties. The existing PVD anti-overflow plating high-temperature resistant protective film has the following problems: in the prior art, the PVD technology can be adopted to coat the film in the camera hole, but the problem of excessive plating is easy to occur in the process of coating the film in the camera hole, and the yield of the coating film is greatly influenced. Therefore, a PVD anti-overflow plating high-temperature resistant protective film is designed.
Disclosure of Invention
Aiming at the defects in the prior art, the utility model provides a PVD (physical vapor deposition) anti-overflow plating high-temperature-resistant protective film, which solves the problems in the background art.
In order to achieve the purpose, the utility model adopts the technical scheme that: the utility model provides a PVD anti-overflow plates high temperature resistant protection film, includes PET substrate layer and special coating, special coating has evenly been paintd to PET substrate layer lower surface, and special coating and PET substrate layer cooperate the use, and special coating can promote the temperature toleration of protection film, has restrained the protection film the condition of wrinkling appearing when the shrink simultaneously, plays fine anti-overflow and plates the effect.
Furthermore, the upper surface of the PET substrate layer is provided with a high-temperature-resistant adhesive layer, the high-temperature-resistant adhesive layer is bonded with the PET substrate layer, the high-temperature-resistant adhesive can keep good bonding performance and corrosion resistance at high temperature, and the service life of the high-temperature-resistant adhesive can be prolonged.
Further, high temperature resistant glue film layer upper surface is equipped with from the type rete, from the type rete and glue with high temperature resistant glue film layer and splice, is used for distinguishing the film that the PET substrate layer surface set up from the type rete.
Furthermore, the size and the thickness of the release film layer and the high-temperature resistant adhesive layer are consistent.
Furthermore, the release film layer is matched with the PET substrate layer for use.
The utility model has the beneficial effects that: the utility model discloses a, through improving, make the staff increase special coating on PET substrate layer surface, coating main part resin composition is polyurethane, ya keli and polyester, and the existence of coating can promote the temperature toleration of protection film, has restrained the protection film the condition of wrinkling appearing when the shrink simultaneously, plays fine anti-overflow and plates the effect, the effectual yield that has promoted the coating film.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a PVD anti-overflow plates resistant high temperature protection film, including PET substrate layer 3 and special coating 4, special coating 4 has evenly been paintd to 3 lower surfaces of PET substrate layer, and special coating 4 cooperatees with the PET substrate layer 3 and uses, and special coating 4 can promote the temperature toleration of protection film, has restrained the protection film the condition of wrinkling when the shrink simultaneously, plays fine anti-overflow and plates the effect.
Wherein, 3 upper surfaces of PET substrate layer are equipped with high temperature resistant glue film 2, high temperature resistant glue film 2 splices with PET substrate layer 3, high temperature resistant glue can keep good bonding performance and corrosion resistance under high temperature, can prolong its life simultaneously, high temperature resistant glue film 2 upper surfaces is equipped with from type rete 1, splice from type rete 1 and high temperature resistant glue film 2, be used for distinguishing the film that 3 surfaces of PET substrate layer set up from type rete 1, from type rete 1 and high temperature resistant glue film 2 size, thickness is all unanimous, use from type rete 1 and PET substrate layer 3 cooperatees.
Referring to fig. 2, the special coating 4 includes polyurethane 5, acrylic 6 and polyester 7, the polyurethane 5, the acrylic 6 and the polyester 7 are used in cooperation, the polyurethane 5 can improve the wear resistance of the special coating 4, the service life of the special coating 4 is prolonged, the acrylic 6 enables the special coating 4 to be easily dyed and processed, the plasticity of the special coating 4 is improved, and the polyester 7 improves the flexibility of the special coating 4.
In conclusion, when the anti-overflow plating protective film is used, a worker adds the special coating 4 on the surface of the PET substrate layer 3 through improvement, the main resin components of the coating are polyurethane 5, acrylic 6 and polyester 7, and the existence of the coating can improve the temperature resistance of the protective film, inhibit the wrinkling condition of the protective film during shrinkage, play a good anti-overflow plating effect and effectively improve the yield of the plated film.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
