Description

Electrostatic Absorption composite membrane

Technical field

The utility model relates to Electrostatic Absorption composite membranes.

Background technique

One kind not coating glue film, adheres on article by product itself Electrostatic Absorption when electrostatic film, plays protection article Effect, be generally chiefly used in being chiefly used in adhesive or glue residual than more sensitive surface glass, eyeglass, bloom plastic rubber surface and The very smooth surface such as acrylic.Electrostatic film external sensation is self-adhesive film less than electrostatic, when PE electrostatic film common electrostatic Film.

The Chinese patent that Authorization Notice No. is CN202965379U, authorized announcement date is on June 5th, 2013 discloses one kind PE Electrostatic Absorption film is compounded with adsorption layer in PE substrate layer upper surface, there is adhesive layer, PE base between PE substrate layer and adsorption layer Material layer with a thickness of 0.04mm, adsorbent layer thickness 0.005mm, adhesive layer with a thickness of 0.005mm.

PE Electrostatic Absorption film is adsorbed on the article of smooth surface using Electrostatic Absorption, the work of protection article can be played With；However when electrostatic force is too strong, air-borne dust is easily adsorbed far from article smooth surface side on Electrostatic Absorption film, it is easy to pollute.

Utility model content

The purpose of the utility model is to provide Electrostatic Absorption composite membrane, have the advantages that reduce outside Electrostatic Absorption.

The above-mentioned technical purpose of the utility model has the technical scheme that

A kind of Electrostatic Absorption composite membrane, including PE film, PET film, printing layer, PP film and two acetic acid set gradually Cellophane, PE film, PET film, PP film and cellulose diacetate film thickness be respectively 0.02,0.04,0.06 And 0.02mm；Side on the cellulose diacetate film far from the PP film is coated with one layer of silicon layer.

In use, PE(polyethylene) film directly contacts with article to be protected, and Electrostatic Absorption rises on article to be protected To the effect of protection；PE film is isolated with the environment in outside by cellulose diacetate (CA) film, and isolation electrostatic interaction is played, Electrostatic force separately is further decreased by coating one layer of silicon layer on cellulose diacetate film, Electrostatic Absorption can on the outside of reduction Energy property, keeps clean surface.

To endure, power is good and the PET(polyester of dimensionally stable) printing layer is disposed thereon by film as carrier, and reduction used Situations such as damaged or fold, occurs for printing layer in journey, keeps printing effect；PET film surfacing is bright and clean, PET film and printing Ink (generally oil-soluble) binding force on layer is strong, and printing layer and PET film active force are strong, are not easily disconnected from.In printing layer two PET film and the good PP(polypropylene of moulding effect is respectively set in side) film, effect is kept with excellent printing.

Further preferably are as follows: be provided with multiple indents on the Electrostatic Absorption composite membrane, indent is thin from cellulose diacetate It is recessed inwardly at film to PET film.

Using the above structure, the coated area for increasing silicon layer further decreases the electrostatic force on surface.

Further preferably are as follows: the cross section of the indent is circle.

Using the above structure, in the identical situation of perimeter, circular area is maximum, further increases the coating of silicon layer Area.

Further preferably are as follows: nano-sized magnesium hydroxide thin layer one is provided between PE film and PET film, printing layer and PP are thin It is provided with nano-sized magnesium hydroxide thin layer two between film, the thickness of nano-sized magnesium hydroxide thin layer one and nano-sized magnesium hydroxide thin layer two is equal For 0.01mm.

Using the above structure, nano-sized magnesium hydroxide has excellent anti-flammability, can protect the article surface of Electrostatic Absorption；It will It is arranged between PE film and PET film, between printing layer and PP film, and PE film, PP film can be first coated in by it On be further processed again, be conducive to by technique substepization, controllably.

Further preferably are as follows: PP film include crystallinity be 58% PP film one, crystallinity be 60% PP film two and crystallization The PP film three that degree is 62%, the thickness of PP film one, PP film two and PP film three is 0.02mm；From PE film to cellulose diacetate On the direction of film, PP film one, PP film two and PP film three are set gradually.

For PP, the more high then strand arrangement of crystallinity is more regular.Using the above structure, be conducive to PP film and printing layer Combination.

Further preferably are as follows: the side Electrostatic Absorption on the PE film far from the PET film has release paper.

The removable setting of release paper, the Electrostatic Absorption composite membrane are thin in PE by release paper Electrostatic Absorption in storage or transport On film, play the role of insulation blocking, reduces the case where PE film electrostatic adsorption power weakens in storage and transportational process and PE is thin Film surface is stained with the case where dirt causes subsequent electrostatic adsorption to die down；Before use, release paper is removed, then electrostatic is inhaled Attached composite membrane Electrostatic Absorption is on article to be protected.

Further preferably are as follows: the side in the release paper far from PE film is stained with by adhesive takes the scraps of paper.

Using the above structure, by taking the scraps of paper to take release paper, the contact for picking and placing release paper process to PE film, side are reduced Just.

In conclusion the utility model has the following beneficial effects:

It can play a protective role by Electrostatic Absorption on smooth surface；Electrostatic Absorption is negligible on the outside of film, keeps Clean surface.
