Abstract
The utility model discloses a double-layer automatic adsorption silica gel protective film. The double-layer automatic adsorption silica gel protective film comprises an upper base material layer and a lower base material layer, wherein one surface of the upper base material layer is glued to the lower base material layer through an adhesive layer, the upper base material layer is a PET (polyethylene terephthalate) film, the lower base material layer is a PET release film, and the adhesive layer is a silica gel adhesive layer. By the manner, the protective film provided by the utility model has an automatic adhesion function, is capable of automatically eliminating air bubbles, can be flatly adhered and is easy to peel off without adhesive residue, the using effect of the double-layer automatic adsorption silica gel protective film is not affected after the protective film is repeatedly adhered, and the double-layer automatic adsorption silica gel protective film is good in water resistance, air temperature resistance and corrosion resistance and has good retention force in high temperature environments.
Description
Technical field
The utility model relates to protective film of electronic product field, particularly relates to the silica gel protected film of a kind of double-deck automatic absorbing.
Background technology
At present, the LCD screen surface of some electronic products, in carrying and use procedure, the polishing scratch that is easily subject to contact staining or the nail etc. of some chemical substances scratches, and conventionally need to attach diaphragm on its surface and makes it to avoid damage and pollute.
For the protection of the screen panels such as mobile phone; the general diaphragm using is to be combined by substrate layer and the adhesive-layer being coated on this substrate layer; the common acrylic glue of the general employing of existing adhesive-layer; belong to solvent-borne type acrylic glue adhesive, its coating is generally difficult to evenly, makes it in the time attaching, easily leave bubble; and some greases, dust etc. are entered in pore; wall-attached surface is caused to corrosion, and its in the time tearing off, can stay be difficult to eliminate vestige, cull is serious.
Utility model content
The technical problem that the utility model mainly solves is: for the deficiencies in the prior art; provide a kind of double-deck automatic absorbing silica gel protected film; there is automatic laminating function; and can automatically get rid of bubble, and adhere to smooth, easily peel off, without cull; repeatedly paste and do not affect result of use; water-tolerant, can gasproof temperature, anti-corrosion, has good confining force under hot environment.
For solving the problems of the technologies described above; the technical scheme that the utility model adopts is: provide a kind of double-deck automatic absorbing silica gel protected film; comprise: upper substrate layer and lower substrate layer; the one side of described upper substrate layer fits by adhesive layer and described lower substrate layer; described upper substrate layer is PET polyester film; described lower substrate layer is PET mould release membrance, and described adhesive layer is silica gel adhesive layer.
In preferred embodiment of the utility model, the thickness of described upper substrate layer is 0.05-0.07mm.
In preferred embodiment of the utility model, the thickness of described adhesive layer is 0.005-0.01mm.
In preferred embodiment of the utility model, the light transmittance of described upper substrate layer and described lower substrate layer all reaches more than 93%.
The beneficial effects of the utility model are: after the low-viscosity silica gel adhesive layer of coated on one side by the upper substrate layer take PET polyester film as raw material; fit and form with the lower substrate layer take PET mould release membrance as raw material; make diaphragm there is automatic laminating function; and can automatically get rid of bubble; and adhere to smooth, easily peel off; without cull; repeatedly paste and do not affect result of use; water-tolerant; can gasproof temperature, anti-corrosion; under hot environment, there is good confining force, be applicable to the surface protection of the glass baseplates such as electronic product.
Accompanying drawing explanation
Fig. 1 is the structural representation of silica gel protected film one preferred embodiment of the double-deck automatic absorbing of the utility model;
In accompanying drawing, the mark of each parts is as follows: 1, upper substrate layer, 2, adhesive layer, 3, lower substrate layer.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Refer to shown in Fig. 1, the utility model embodiment comprises:
The silica gel protected film of a kind of double-deck automatic absorbing; comprise: upper substrate layer 1 and lower substrate layer 3; the one side of described upper substrate layer 1 fits by adhesive layer 2 and described lower substrate layer 3; described upper substrate layer 1 is PET polyester film; described lower substrate layer 3 is PET mould release membrance; described adhesive layer 2 is silica gel adhesive layer, has Automatic-exhausting pickle function, can automatic absorbing when attaching.
Wherein, the thickness of described upper substrate layer 1 is 0.05-0.07mm, and quality is harder, relatively scratch resistance, and water-tolerant, not easy to wear, good hand touch, is quick on the draw.
The thickness of described adhesive layer 2 is 0.005-0.01mm.
The light transmittance of described upper substrate layer 1 and described lower substrate layer 3 all reaches more than 93%; its mechanical performance is good, and rigidity, hardness and toughness are high, puncture-resistant, rub resistance, heatproof, corrosion-resistant; and transparency is good, can under the state of laminating protective material, carry out the visual examination of blooming.
The adhesion strength of described adhesive layer 2 is 3-20 g/25.4mm, and its viscosity is low, and adhesiveness is good, easily pastes easily openable, and after attaching, adhesion strength rheological parameters' change with time is little, can repeatedly paste.
The utility model has disclosed the silica gel protected film of a kind of double-deck automatic absorbing; after the low-viscosity silica gel adhesive layer of coated on one side by the upper substrate layer take PET polyester film as raw material; fit and form with the lower substrate layer take PET mould release membrance as raw material; make diaphragm there is automatic laminating function; and can automatically get rid of bubble; and adhere to smooth, easily peel off; without cull; repeatedly paste and do not affect result of use; water-tolerant; can gasproof temperature, anti-corrosion, under hot environment, there is good confining force, be applicable to the surface protection of the glass baseplates such as electronic product.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
