Description

A kind of Electrostatic Absorption composite membrane

Technical field

The utility model relates to a kind of 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.

Printing when being printed on the PE Electrostatic Absorption film of the prior art, generally in surface layer coating antistatic printing ink formation Layer, printing layer is exposed for a long time in air, and printing effect is gradually deteriorated.

Utility model content

The purpose of the utility model is to provide a kind of Electrostatic Absorption composite membrane, having, which reduces printing effect, weakens the excellent of speed Point.

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

A kind of Electrostatic Absorption composite membrane, including set gradually PE film, EVOH film one, PET film, printing layer and EVOH film two, PE film, EVOH film one, PET film and EVOH film two thickness be respectively 0.02,0.02,0.04 and 0.03mm。

Using the above structure, to endure, power is good and the PET(polyester of dimensionally stable) printing layer is arranged at it as carrier film On, situations such as damaged or fold occurs for printing layer in use process is reduced, printing effect is kept；PET film surfacing is bright and clean, PET film and ink (generally oil-soluble) binding force in printing layer are strong, and printing layer and PET film active force are strong, are not easy to take off From.

EVOH(ethylene-vinyl alcohol copolymer) excellent blocking effect is presented to gas, solvent film, with PET film Stickiness is strong and the two it is compound after be still able to maintain excellent barrier to gas and solvent, so gas and moisture in external environment A possibility that entering printing layer from a kind of two sides of Electrostatic Absorption composite membrane is extremely low, reduces the corruption of moisture and air to printing layer Erosion, improves the service life of printed matter.

In use, PE film is inside, with the very smooth surface such as glass, eyeglass, bloom plastic rubber surface and acrylic It directly contacts, a kind of Electrostatic Absorption composite membrane Electrostatic Absorption plays the role of insulation blocking on article surface, and easy because of PET The electrostatic adsorption force of a kind of Electrostatic Absorption composite membrane and article surface can be improved in static electrification, reduces and is detached from possibility.

Further preferably are as follows: PVA film one, EVOH film two and printing are provided between EVOH film one and PET film PVA film two is provided between layer, and the thickness of PVA film one and PVA film two is respectively 0.02 and 0.03mm.

Using the above structure, PVA(polyvinyl alcohol) it can be used as between EVOH film one and PET film and EVOH film two Adhesive between printing layer exists, and improves bonding strength, while its gas and solvent barrier height can further improve resistance Every property.

Further preferably are as follows: nano-sized magnesium hydroxide thin layer one is provided between EVOH film one and PVA film one, EVOH is thin Nano-sized magnesium hydroxide thin layer two, nano-sized magnesium hydroxide thin layer one and nano-sized magnesium hydroxide are provided between film two and PVA film two The thickness of thin layer two is 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 EVOH film and PVA film, good dispersion.

Further preferably are as follows: the side on EVOH film two far from nano-sized magnesium hydroxide thin layer two is provided with PP film, PP Film with a thickness of 0.07mm.

Using the above structure, play the role of preferable moulding and fluid partitioning.

Further preferably are as follows: the side on PP film far from EVOH film two is provided with cellulose diacetate film, two vinegar Cellulose acetate films with a thickness of 0.03mm.

Using the above structure, cellulose diacetate (CA) film surface is bright and clean, less scaling, using it as outside, keeps whole It is clean；CA film is arranged close to PP film, and the junction of the two is fine and close, further increases barrier property.

Further preferably are as follows: PP film include crystallinity be 58% PP film one, crystallinity be 65% PP film two and crystallization The PP film three that degree is 58%, the thickness of PP film one, PP film two and PP film three is respectively 0.02,0.03 and 0.02mm；Extremely from PE film On the direction of EVOH film two, 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, on the one hand it is located at the PP film of two sides One and PP, three fusing points of film are slightly lower, are conducive in conjunction with EVOH film two, CA film, on the other hand use symmetrical structure, reduce and become A possibility that shape.

In conclusion the utility model has the following beneficial effects:

It can play a protective role by Electrostatic Absorption on smooth surface；Printing layer is isolated with external environment, water proof trapping Property it is excellent, the printing fastness of printing layer is strong, and printing effect is good and effect keeps long.
