Description
Technical field
The present invention relates to a kind of automatic exhaust-type protective films.
Background technology
With the rapid development of the products such as smart mobile phone and tablet computer, also formed in recent years in the accessory in these fields
Huge industrial chain, the electronic curtain protective film for these products is exactly one of typical case.Screen protecting film currently on the market
Type is various, but is typically all the transparent thin-film material by electrostatic or adhesive attachment on the screen.This type products
The disadvantage is that easy to fall off, blistering, short life is not anti-scratch, not antidetonation, is not easy to paste.
Invention content
For the shortcomings of the prior art, the present invention provides a kind of automatic exhaust-type protective film.
Technical scheme of the present invention is summarized as follows：
A kind of automatic exhaust-type protective film comprising have exhaust level and PET base material layer；
Wherein, the exhaust level includes the material of following parts by weight：
Preferably, the automatic exhaust-type protective film, wherein further include having 1-2 parts by weight in the exhaust level
Sodium methyl silicate.
Preferably, the automatic exhaust-type protective film, wherein further include having 1-2 parts by weight in the exhaust level
Ethylene glycol dimethacrylate.
Preferably, the automatic exhaust-type protective film, wherein further include having 1-2 parts by weight in the exhaust level
Poly- D- lactides.
Preferably, the automatic exhaust-type protective film, wherein the number-average molecular weight of the poly- D- lactides is
5000-6000g/mol。
Preferably, the automatic exhaust-type protective film, wherein the number-average molecular weight of the dimethyl silicone polymer is
16000-18000g/mol。
Preferably, the automatic exhaust-type protective film, wherein the number-average molecular weight of the silane modified polyether resin
For 8000-9000g/mol.
The beneficial effects of the invention are as follows：This case is improved by the exhaust layer component to existing automatic exhaust protective film,
To improve automatic row's bubble ability of exhaust level so that exhaust level can still have outstanding row after tearing patch repeatedly and steep ability, drop
The fitting difficulty of minimum living cuticula；Light transmittance, adhesion strength and the weather resistance for also ensuring protective film simultaneously, effectively reduce residual
Glue rate；The automatic exhaust-type protective film of this case is suitable for the fields such as electronic curtain.
Specific implementation mode
With reference to embodiment, the present invention is described in further detail, to enable those skilled in the art with reference to specification
Word can be implemented according to this.
The automatic exhaust-type protective film of an embodiment is listed in this case comprising has exhaust level and PET base material layer；
Wherein, exhaust level includes the material of following parts by weight：
Based on dimethyl silicone polymer, amino silicone is used to cooperate with oneself for improving dimethyl silicone polymer exhaust level
Dynamic row's bubble ability；Hexamethyldisiloxane is used to improve the cohesive force of dimethyl silicone polymer system, to reduce the residual of exhaust level
Rate, that improves exhaust level tears patch number repeatedly；The hydrophobic performance of dimethyl silicone polymer can be improved in silane modified polyether resin, with
Absorption rate of the exhaust level to moisture in air is reduced, so that exhaust level has metastable row's bubble within a certain period of time
Performance, in order to leave pad pasting for, person's time enough goes to operate, and will not lead to exhaust level in the short time tearing patch repeatedly
Bubble ability is arranged to decline.A small amount of silane modified polyether resin can be additionally used in the integral rigidity for improving exhaust level, reduce exhaust level
Shrinkage stress can be linearly evenly bonded forward, in order to which exhaust level with screen when being bonded without causing local patch
Sum velocity is inconsistent, causes in fit area producing bubbles inside.
Wherein, in exhaust level further include the sodium methyl silicate for there are 1-2 parts by weight.Sodium methyl silicate can improve exhaust level and exist
Toughness under ultraviolet and ageing resistance so that protective film has more longlasting service life.
Wherein, in exhaust level further include the ethylene glycol dimethacrylate for there are 1-2 parts by weight.Dimethacrylate second two
The effect of alcohol ester is the cohesive strength for improving exhaust level entirety and coated integral rigidity after curing.
Wherein, in exhaust level further include the poly- D- lactides for there are 1-2 parts by weight.Poly- D- lactides can adjust exhaust level with
The closely sealed rate of screen, the row to improve exhaust level steep effect, reduce remaining number of bubbles.In addition, poly- D- lactides are also
It can effectively inhibit dimethyl silicone polymer in the rate of decay of the viscosity after being bonded repeatedly, to improve exhaust level repeatedly
Tear patch ability.It will be than poly- with the modification power of the Poly L-lactide of molecular formula but various configuration in this respect with poly- D- lactides
Weak more of D- lactides, also, preferably, the number-average molecular weight of poly- D- lactides is preferably 5000-6000g/mol, with
Obtain more preferably modified effect.
Wherein, the number-average molecular weight of dimethyl silicone polymer is preferably 16000-18000g/mol.
Wherein, the number-average molecular weight of silane modified polyether resin is preferably 8000-9000g/mol.
Table one lists the exhaust layer formula of different embodiments and the performance test parameter of automatic exhaust-type protective film obtained：
Table one
Although the embodiments of the present invention have been disclosed as above, but its is not only in the description and the implementation listed
With it can be fully applied to various fields suitable for the present invention, for those skilled in the art, can be easily
Realize other modification, therefore without departing from the general concept defined in the claims and the equivalent scope, the present invention is simultaneously unlimited
In specific details.
