Description

A kind of optical release liner

Technical field

The utility model is related to thin film technique field, more particularly to a kind of optical release liner.

Background technology

Mould release membrance refers to the film that surface has separation property, after mould release membrance is contacted under limited conditions with specific material Without viscosity, or slight viscosity.

Mould release membrance, also known as stripping film, barrier film, seperation film, adhesive block film, fractal film, film, plastic sheeting, masking hole film, silicon Oil film, silicone oil paper, antiadhesion barrier, skidding film, that paper of day, release liners.Under normal circumstances in order to increase the off-type force of plastic sheeting, meeting Plastic sheeting is done into plasma treatment, or applies fluorine treatment, or apply silicon mould release on the top layer of film material, allow it for various Different organic pressure sensitive adhesives can show extremely light and stabilization off-type force.

Have the advantages that to isolate due to mould release membrance, fill, protect, be easily peeled off, therefore be widely used in various electricity In the fields such as son, communication, machinery.

With mobile phone, the popularization of the electronic product such as panel computer, the demand to the good mould release membrance of translucency is increasing, while The mould release membrance being fitted on electronic product can not influence to use feel and outward appearance, otherwise cause experience not good.

Additionally, mould release membrance accumulates a large amount of electrostatic charges during stripping and laminating, the accumulation of a large amount of electrostatic charges can be release Producing the generation of fatefulue destruction risk, a large amount of electrostatic charges during the use of film to electronic product can also adsorb dust grain Son, causes bad in electronic product production process, and being fitted with electronic product aeration of easily produce of mould release membrance is attractive in appearance.

Utility model content

In order to solve the problems of the prior art, the purpose of this utility model is to provide a kind of optical release liner.

To achieve these goals, the utility model is adopted the following technical scheme that：A kind of optical release liner, including antistatic Layer, substrate layer and release film layer, the antistatic backing are provided with a plurality of first grooves, and the antistatic backing outside is provided with base Material layer, the substrate layer is provided with the second groove in the first groove correspondence position, what first groove and the second groove were surrounded Space is filled with adhesive layer, and the substrate layer outside is provided with release film layer, is provided between the substrate layer and release film layer Intermediate layer.

Preferably, the substrate layer is pet layer.

Preferably, the adhesive that the adhesive layer is used is silica gel adhesive.

Preferably, the release film layer is silicon layer.

Preferably, the intermediate layer is Nano-meter SiO_2₂Layer.

Preferably, the Nano-meter SiO_2₂SiO in layer₂It is spherical nanoparticles, the SiO₂A diameter of 100- 200nm。

Preferably, the gross thickness of the optical release liner is 50-55 μm.

Compared with prior art, the beneficial effect that the utility model is realized：The utility model optical release liner is provided with One groove and the second groove, adhesive layer are arranged in the space that the first groove and the second groove are surrounded, two designs of groove So that the connection of antistatic backing and base material interlayer is more consolidated, the thickness of adhesive layer is reduced, while two design sections of groove Space has been saved, the thickness of whole optical release liner has been reduced, the translucency of optical release liner has been improve；The utility model optics from Type film is provided with antistatic backing so that optical release liner is antistatic, will not produce charge accumulated, it is to avoid electronic product is brought Infringement, while reducing the generation of dust；The utility model optical release liner sets intermediate layer between substrate layer and release film layer, in Interbed is Nano-meter SiO_2₂Layer, Nano-meter SiO_2₂Specific surface area is big, and absorption affinity is strong, and the interaction force with release film layer is big, optics from It is easily peelable, it is to avoid to leave cull when type film is peeled off.

Brief description of the drawings

The utility model is further described below in conjunction with the drawings and specific embodiments：

Fig. 1 is the structural representation of the utility model optical release liner.

Wherein：Antistatic backing 1, the first groove 1-1, substrate layer 2, the second groove 2-1, release film layer 3, adhesive layer 4, in Interbed 5.

Specific embodiment

Such as Fig. 1, a kind of optical release liner, including antistatic backing 1, substrate layer 2 and release film layer 3, the antistatic backing 1 set It is equipped with 3 the first groove 1-1, the outside of the antistatic backing 1 is provided with substrate layer 2, the substrate layer 2 is in the first groove 1-1 pairs Answer position to be provided with the space that the second groove 2-1, the first groove 1-1 and the second groove 2-1 surround and be filled with adhesive layer 4, the outside of the substrate layer 2 is provided with release film layer 3, and intermediate layer 5 is provided between the substrate layer 2 and release film layer 3.

The design of the antistatic backing 1 causes that optical release liner is antistatic, will not produce charge accumulated, it is to avoid to electronics Product brings infringement, while reducing the generation of dust.

The substrate layer 2 is pet layer.

Antistatic backing 1 is respectively arranged with the first groove 1-1 and the second groove 2-1 with substrate layer 2 in correspondence position, and first is recessed The space that groove 1-1 and the second groove 2-1 are surrounded is used to accommodate adhesive layer 4, saves the space of the occupancy of adhesive layer 4, reduces The thickness of whole optical release liner.

The adhesive that the adhesive layer 4 is used is silica gel adhesive.

The release film layer 3 is silicon layer.

The intermediate layer 5 is Nano-meter SiO_2₂Layer, the Nano-meter SiO_2₂SiO in layer₂It is spherical nanoparticles, the SiO₂ A diameter of 100-200nm, this Nano-meter SiO_2₂Layer has larger specific surface area, and the absorption affinity to release film layer 3 is strong, in optics When mould release membrance is peeled off, release film layer 3 is easily peeled off, and avoids leaving cull.

The gross thickness of the optical release liner be 50-55 μm, the translucency of optical release liner is good, and the gross thickness light Learn mould release membrance and do not interfere with feel and outward appearance, it is ensured that experience effect of the client to electronic product.

Above-mentioned specific embodiment is exemplary, is to preferably make skilled artisans appreciate that originally Patent, it is impossible to be not understood as including this patent the limitation of scope；As long as according to disclosed in this patent spirit made appoint How with change or modification, the scope that this patent includes is each fallen within.
