The mucigel of existing silica gel protected film is usually what is be made up of acrylic glue, is easily inhaled after being taken off from screen Attached grease, dust etc., and cull is easily left on screen, this kind of silica gel protected film can only be disposable, it is impossible to is posted, makes Into the waste of diaphragm.In consideration of it, be necessary exploitation one kind can be posted, reusable silica gel protected film.
The content of the invention
To solve the deficiencies in the prior art, can easily it be posted it is an object of the invention to provide one kind, nonexpondable Silica gel protected film.
In order to realize above-mentioned target, the present invention is adopted the following technical scheme that：
The silica gel protected film that can be posted, including substrate layer, adhesive layer and the release layer set gradually, the adhesive layer is by such as The each component of lower parts by weight is made：20-50 parts of organosilicon adhesive, 3-8 parts of curing agent, 5-10 parts of catalyst, 1-3 parts of coupling agent And 5-15 parts of dihydric alcohol.
Preferably, aforementioned substrates layer is PET film, and thickness is 80-120 μm.
It is highly preferred that foregoing release layer is PET mould release membrances, thickness is 10-100 μm.
More preferably, the thickness of foregoing adhesive layer is 50-150 μm.
It is highly preferred that aforementioned curing agent is DOW CORNING Syl-off 7028.
Preferably, Above-mentioned catalytic agent is spherical nano TiO 2 or spherical nano-silicon dioxide, and average grain diameter is 50- 120nm。
It is highly preferred that aforementioned coupling agents are Silane coupling agent KH550.
More preferably, foregoing dihydric alcohol is ethylene glycol or condensation ethylene glycol.
More preferably, the silica gel protected film 1-3min of ultraviolet light, can more rapidly, high-quality be realized silica gel protected before being posted Film is posted.
It is further preferred that the preparation method of foregoing adhesive layer is：Dihydric alcohol is placed in a container and ultrasonic magnetic force Stirring, will put into dihydric alcohol after catalyst grinding distribution, is warming up to 40-60 DEG C, adds organosilicon gluing into container successively Agent and curing agent, persistently stir 3-6h, are cooled to 30 DEG C, add coupling agent, stir.
The present invention is advantageous in that：Noresidue when the silica gel protected film of the present invention is torn from screen, and film surface It is difficult to be stained with the pollutants such as dust, it is possible to achieve be posted；Being posted the silica gel protected film 1-3min of preceding ultraviolet light can then optimize It is posted effect；Catalyst in adhesive layer is vital for the effect that is posted of silica gel protected film.
Embodiment
Make specific introduce to the present invention below in conjunction with specific embodiment.
Embodiment 1
The present embodiment turns the silica gel protected film of note, including the substrate layer, adhesive layer and the release layer that set gradually, wherein： Substrate layer is PET film, and thickness is 80-120 μm；Release layer is PET mould release membrances, and thickness is 10-100 μm；The thickness of adhesive layer Spend for 50-150 μm, be made by each component of following parts by weight：40 parts of organosilicon adhesive, 5 parts of curing agent, 8 parts of catalyst, idol Join 10 parts of 2 parts of agent and dihydric alcohol.
The preparation method of adhesive layer is：Dihydric alcohol is placed in a container and ultrasonic magnetic agitation, catalyst is ground After scattered in input dihydric alcohol, 40-60 DEG C is warming up to, organosilicon adhesive and curing agent is added into container successively, persistently stirs 3-6h is mixed, 30 DEG C are cooled to, coupling agent is added, stirs.
Wherein, curing agent is DOW CORNING Syl-off 7028, and catalyst is spherical nano TiO 2 or ball shaped nano two Silica, average grain diameter is 50-120nm, and coupling agent is Silane coupling agent KH550, and dihydric alcohol is ethylene glycol or condensation ethylene glycol.
Embodiment 2
The silica gel protected film for turning note of the present embodiment, its structure and preparation technology are identical with embodiment 1, and the main distinction exists In the constituent content of adhesive layer, it is specially：20 parts of organosilicon adhesive, 3 parts of curing agent, 5 parts of catalyst, 1 part of coupling agent and 5 parts of dihydric alcohol.
Embodiment 3
The silica gel protected film for turning note of the present embodiment, its structure and preparation technology are identical with embodiment 1, and the main distinction exists In the constituent content of adhesive layer, it is specially：50 parts of organosilicon adhesive, 8 parts of curing agent, 10 parts of catalyst, 3 parts of coupling agent and 15 parts of dihydric alcohol.
Comparative example
The silica gel protected film of this comparative example, including substrate layer, adhesive layer and the release layer set gradually, wherein：Substrate layer is PET film, thickness is 80-120 μm；Release layer is PET mould release membrances, and thickness is 10-100 μm；The thickness of adhesive layer is 50- 150 μm, it is made by each component of following parts by weight：40 parts of organosilicon adhesive, 5 parts of curing agent, 2 parts of coupling agent and dihydric alcohol 10 Part.
