Abstract

The utility model discloses a PE electrostatic adsorption film which comprises a PE base material layer, an adsorption layer compounded on the upper surface of the PE base material layer and an adhesion layer between the PE base material layer and the adsorption layer, wherein the thickness of the PE base material layer is 0.04mm; the thickness of the adsorption layer is 0.005mm; the thickness of the adhesion layer is 0.005mm; the adsorption layer is a mixture layer of main body resin, tackifying resin and a stripping force stabilizer; and the adhesion layer is a layer of mixture of adhesive resin and an ethylene-vinyl acetate copolymer. According to the utility model, since adhesive resin and a stripping force stabilizer are added to the adsorption layer, the PE electrostatic adsorption film has the advantage of adhesion stability, can keep firm adhesion at high temperature, avoids residual adhesive after torn off, and also realizes good initial adhesion at low temperature.

Description

A kind of PE Electrostatic Absorption film

Technical field

The utility model relates to a kind of display screen protection film, particularly a kind of PE Electrostatic Absorption film.

Background technology

PE Electrostatic Absorption film is a kind of display screen protection film of electronic product; it can make film body with electrostatic charge in early stage during sided corona treatment; therefore; can utilize Electrostatic Absorption effect between itself and display screen surface to be attached to the display screen surface of the products such as panel computer, smart mobile phone, television set, with avoid display screen in transportation, preserve or the Surface During that uses is damaged or scratches.

Existing PE Electrostatic Absorption film or PE are unstable with the attaching of the low mucous membrane of glue; after being attached on display screen; As time goes on; particularly in greater than the hot environment of 60 degrees centigrade; the peeling force of diaphragm often has rising in various degree; can occur diaphragm when serious and be difficult to take off and fall the problem such as glue, affect the outward appearance of electronic product.

In addition, existing PE Electrostatic Absorption film or PE are not strong with the low temperature tack of the low mucous membrane of glue, usually occur attaching not firm phenomenon when using in low temperature environment.

The utility model content

For solving the problems of the technologies described above, the utility model provides a kind of PE Electrostatic Absorption film, and to reach stable performance, it is firm also to keep attaching under higher temperature, and takes the purpose without cull off.

For achieving the above object, the technical solution of the utility model is as follows: a kind of PE Electrostatic Absorption film, comprise the PE substrate layer, and described PE substrate layer upper surface is compounded with adsorption layer, between described PE substrate layer and described adsorption layer, adhesive linkage is arranged; Described PE substrate layer thickness is 0.04mm; Described adsorbent layer thickness is 0.005mm; Described thickness of adhibited layer is 0.005mm.

Pass through technique scheme, a kind of PE Electrostatic Absorption film that the utility model provides, be with electrostatic charge in the sided corona treatment in early stage, the adsorption layer surface need not to use the viscose glue material, utilize the Electrostatic Absorption effect to be attached to the display surface of electronic product, add and added the peeling force stabilizing agent in adsorption layer, make peeling force stable, avoided peeling force to increase the problem that improves with the overlay film time, have advantages of that attaching is stable, make it also can keep attaching firm under higher temperature, and take off without cull.

Description of drawings

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or description of the Prior Art.

Fig. 1 is the disclosed a kind of PE Electrostatic Absorption film cross-sectional schematic of the utility model embodiment.

The represented corresponding construction title of numeral in figure:

1, PE substrate layer 2, adhesive linkage 3, adsorption layer

The specific embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.

According to Fig. 1, the utility model provides a kind of PE Electrostatic Absorption film, comprise that thickness is the PE substrate layer 1 of 0.04mm, and to be compounded in PE substrate layer 1 upper surface thickness be the adsorption layer 3 of 0.005mm, be provided with bonding adhesive linkage 2 both between PE substrate layer 1 and adsorption layer 3, adhesive linkage 2 is that thickness is adhering resin and the ethylene-vinyl acetate copolymer mixture layer of 0.005mm, have good flexibility, and chemical stability is strong.

adsorption layer 3 is matrix resin, the mixture layer of tackifying resin and peeling force stabilizing agent, wherein, tackifying resin can be Petropols, (hydrogenation) rosin and ester thereof, (hydrogenation) terpenes and modifier thereof, low molecular mass polyisobutene (PIB), low molecular mass polybutene (PB) and low molecular mass polyisoprene (PIP), adding of tackifying resin can make PE Electrostatic Absorption film that better low temperature tack is arranged, even during first the use, environment temperature is hanged down also can stablize and is attached to display screen surface, the peeling force stabilizing agent can be polyethylene glycol, polyethyleneimine: peace derivative, chain alkyl salt or other and matrix resin have the surfactant of compatibility, the peeling force stabilizing agent can form the discontinuous non-sticky tympan of one deck between adsorption layer 3 and display screen surface, thereby stop the rising of peeling force, and, the area of this tympan increases gradually with the increase of the time of attaching, until reach steady state value.

A kind of PE Electrostatic Absorption film that the utility model provides, die body has been with electrostatic charge in the sided corona treatment in early stage, adsorption layer 3 surfaces need not to use the viscose glue material, utilize the Electrostatic Absorption effect to be attached to the display surface of electronic product, added the peeling force stabilizing agent in adsorption layer 3, avoided peeling force to increase the problem that improves with the overlay film time, made it also can keep attaching firm under higher temperature, and taken off without cull.

In addition, also added tackifying resin in adsorption layer 3, the utility model has been used under low temperature environment also have good tack.

To the above-mentioned explanation of disclosed a kind of PE Electrostatic Absorption film embodiment, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from spirit or scope of the present utility model, realization in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
