Description
Technical Field
The utility model relates to a multi-functional protection film of electronic product, in particular to TPF protection film.
Background
While OLED cell phone panel shipments are increasing every year, LCD smart phone panel shipments are decreasing, SDCC anticipates that OLED cell phone panel shipments (including rigid, flexible, and foldable) will exceed LCDs for the first time in 2021. By means of the method, 12 AMOLED production lines are built at home at present, and the AMOLED production lines which are invested in the continental year 2020 are expected to be totally produced in mass. At present, Weixinuo (national development), Jingdong and Hui have realized the mass shipment of OLED panels. In the process of manufacturing a poled (plastic OLED) panel, a protective film including an OLED element and a sealing layer is required. In the prior art, the protective film has poor air exhaust performance and unstable viscosity, and influences the product quality.
SUMMERY OF THE UTILITY MODEL
For overcoming the used protection film air discharge of electronic components nature that exists among the prior art not good, and viscidity unstable, influence product quality's problem, the utility model provides a TPF protection film.
The specific technical scheme is as follows:
the utility model provides a TPF protection film, includes substrate layer, glue film and leaves the type layer, the laminating of glue film lower surface is being from type layer upper surface, the laminating of glue film upper surface has first substrate layer, the laminating of first substrate layer upper surface has antistatic coating, it has the second substrate layer to laminate from type layer lower surface, the laminating of second substrate layer lower surface has antistatic coating.
Preferably, the glue layer is a polyethylene terephthalate film, and the surface of the polyethylene terephthalate film is coated with an antistatic polyurethane pressure-sensitive adhesive.
Preferably, the substrate layer is a transparent polyethylene terephthalate film.
Preferably, the release layer is a polyethylene terephthalate film.
Preferably, the release layer is an antistatic release layer.
Compared with the prior art, the utility model following beneficial effect has:
the application provides a TPF protective film, which adopts a modified polyurethane adhesive, has no adhesive residue on an object to be pasted, is antistatic and has small climbing time; the polyethylene glycol terephthalate is used as a base material and a release film, so that the air-release property is high, the viscosity is stable (low-climbing), the pollution is low, the characteristics of good uniformity and good reliability are realized, and the special release film has the advantages of stable structure and excellent processability.
Drawings
Fig. 1 is the structure schematic diagram of the TPF protective film of the present invention.
In the figure, 1-antistatic coating, 2-first base material layer, 3-adhesive layer, 4-release layer and 5-second base material layer.
Detailed Description
The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
The utility model provides a TPF protection film, as shown in figure 1, including substrate layer, glue film 3 and from type layer 4, the laminating of 3 lower surfaces of glue film is from type layer 4 upper surface, and the laminating of 3 upper surfaces of glue film has first substrate layer 2, and the laminating of 2 upper surfaces of first substrate layer has antistatic coating 1, and the laminating of 4 lower surfaces of type layer has second substrate layer 5, and the laminating of 5 lower surfaces of second substrate layer has antistatic coating 1. Preferably, the adhesive layer 3 is a polyethylene terephthalate film, and the surface of the polyethylene terephthalate film is coated with an antistatic polyurethane pressure sensitive adhesive. The substrate layer is transparent polyethylene terephthalate membrane in this application. The release layer 4 is a polyethylene terephthalate film. Further preferably, the release layer 4 is an antistatic release layer 4.
The TPF protective film is of a multilayer structure consisting of an antistatic polyethylene terephthalate substrate, an adhesive layer 3 (a modified polyurethane pressure-sensitive adhesive layer 3) and a special release layer 4. The use and performance of the protective film are directly affected by the interlayer structure and the performance of the glue layer 3. The surface of the polyethylene glycol terephthalate substrate is subjected to antistatic treatment, and the antistatic layer is stable and has good weather resistance. The polyurethane adhesive layer 3 is formed by coating polyethylene glycol terephthalate with an antistatic polyurethane pressure-sensitive adhesive (one or more of lithium bis (trifluoromethyl) sulfonyl imide, polydimethylsiloxane containing polyether modified acrylic acid functional groups, polyether modified hydroxyl functional polydimethylsiloxane solution and bis (trifluoromethyl) sulfonyl imide salt are added into the polyurethane pressure-sensitive adhesive) to realize the design of no residual adhesive, static resistance and small climbing over time on an attached object.
The TPF protective film may be formed by a known method for manufacturing a double-sided tape, and may be formed by knife coating, roll coating, gravure coating, slot extrusion coating, spray coating, die coating, or the like. The utility model discloses in, the coating is extruded to preferred slit formula or scraper coating, and more excellent slit formula is extruded the coating.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
