Abstract
The invention discloses a double-layered silica gel protective film capable of being automatically adsorbed. The double-layered silica gel protective film comprises an upper base material layer and a lower base material layer, wherein one face of the upper base material layer is fitted with the lower base material layer through an adhesive layer; the upper base material layer is a PET (Polyethylene Terephthalate) polyester thin film; the lower base material layer is a PET release film; and the adhesive layer is a silica gel adhesive layer. With the adoption of the manner, the protective film disclosed by the invention has the function of automatically attaching and can automatically remove air bubbles; the protective film is flat to stick, is easy to peel and has no residual adhesive; the use effect is not influenced by repeatedly sticking the protective film; and the protective film is good in water resistance, can resist air temperature and corrosion, and has the good retentiveness under a high-temperature environment.
Description
Technical field
The present invention relates to the protective film of electronic product field, particularly relate to the silica gel protected film of a kind of double-deck automatic absorbing.
Background technology
At present, the LCD screen of some electronic products surface, in carrying and use procedure, the polishing scratch that easily is subject to the contact staining of some chemical substances or nail etc. scratches, and usually need to attach diaphragm on its surface and make it to avoid damage and pollution.
Protection for screen panels such as mobile phones; the general diaphragm that uses is to be combined by substrate layer and the adhesive-layer that is 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 generally is difficult to evenly, makes it easily stay bubble when attaching; and some greases, dust etc. are entered in pore; wall-attached surface is caused corrosion, and it can stay the vestige that is difficult to eliminate when tearing off, cull is serious.
Summary of the invention
The technical problem that the present invention mainly solves is: for the deficiencies in the prior art; provide a kind of double-deck automatic absorbing silica gel protected film; has the 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, but gasproof temperature, anti-corrosion have good confining force under hot environment.
For solving the problems of the technologies described above; the technical scheme that the present invention 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 the PET polyester film; described lower substrate layer is the PET mould release membrance, and described adhesive layer is the silica gel adhesive layer.
In a preferred embodiment of the present invention, the thickness of described upper substrate layer is 0.05-0.07mm.
In a preferred embodiment of the present invention, the thickness of described adhesive layer is 0.005-0.01mm.
In a preferred embodiment of the present invention, the light transmittance of described upper substrate layer and described lower substrate layer all reaches more than 93%.
The invention has the beneficial effects as follows: by after the low-viscosity silica gel adhesive layer of the coated on one side of the upper substrate layer take the PET polyester film as raw material; fit with lower substrate layer take the PET mould release membrance as raw material and form; make diaphragm have the 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; but gasproof temperature, anti-corrosion; good confining force is arranged under hot environment, be applicable to the surface protection of the glass baseplates such as electronic product.
Description of drawings
Fig. 1 is the structural representation of silica gel protected film one preferred embodiment of the double-deck automatic absorbing of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, upper substrate layer, 2, the adhesive layer, 3, lower substrate layer.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made more explicit defining.
See also shown in Figure 1ly, the embodiment of the present invention 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 the PET polyester film; described lower substrate layer 3 is the PET mould release membrance; described adhesive layer 2 is the silica gel adhesive layer, has the Automatic-exhausting pickle function, but automatic absorbing during 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 carry out the visual examination of blooming under the state of applying protective material.
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, the adhesion strength rheological parameters' change with time is little, can repeatedly paste.
The present invention has disclosed the silica gel protected film of a kind of double-deck automatic absorbing; by after the low-viscosity silica gel adhesive layer of the coated on one side of the upper substrate layer take the PET polyester film as raw material; fit with lower substrate layer take the PET mould release membrance as raw material and form; make diaphragm have the 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; but gasproof temperature, anti-corrosion has good confining force under hot environment, be applicable to the surface protection of the glass baseplates such as electronic product.
The above is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present invention.
