Abstract

The invention provides a protection film used on electronic product screens. The protection film is characterized in that the lower surface of a film base material layer is bonded with a release film by a pressure sensitive adhesive; the pressure sensitive adhesive is obtained by the following steps: adding micron SiO2 powder, micron Al2O3 powder and a silane coupling agent to a first solvent to obtain a pre-dispersion solution; adding nano SiO2 powder, nano Al2O3 powder and isocyanate to the pre-dispersion solution to obtain a prepared pre-dispersion solution; adding 70-80 parts of methyl methacrylate, 25-38 parts of ethyl acrylate and 15-18 parts of dimethyldiethoxysilane to a second solvent to obtain a polymer solution; mixing the prepared pre-dispersion solution with the polymer solution and adding rosin resin, terpene resin, an azo compound and an N-nitroso compound in sequence, thus obtaining the pressure sensitive adhesive. The protection film has the advantage and effect that sedimentation of the SiO2 powder and the Al2O3 powder in a system is avoided; the adhesion and the high temperature resistance are improved.

Description

For the protective membrane of electronic product screen
Technical field
The present invention relates to a kind of protective membrane, particularly a kind of protective membrane for electronic product screen.
Background technology
Prior art is subject to scratch or wearing and tearing in order to avoid electronic product screen surface, affects result of use, generally can paste in the screen surface of electronic product and foretell screen protecting film.Protective membrane is generally made up of substrate layer and the adhesive layer be coated on this substrate layer.This is also more and more higher to the requirement of adhesive tape, usually need clinging power strong and thickness at thinner adhesive tape.For electronic product or other products, once use adhesive tape, then need this adhesive tape can maintain viscosity when difference variation is large always, and can easily sizing agent be peeled off from film.
Summary of the invention
The invention provides a kind of protective membrane for electronic product screen, this protective membrane improves vinylformic acid sizing agent roughness when not increasing particle diameter, avoid cluster, it also avoid SiO 2powder, Al 2o 3the sedimentation of powder in system, improves and base material bonding force.
For achieving the above object, the technical solution used in the present invention is: a kind of protective membrane for electronic product screen, described protective membrane comprises a thin film based sheet material layers, this thin film based sheet material layers applied atop primary antibodie scraping coating, and this thin film based sheet material layers lower surface is by pressure-sensitive adhesive and a release film adhering junction;
Described pressure-sensitive adhesive is obtained by following steps, comprises the following steps:
Step 1. is by 0.2 ~ 0.5 part of micron order SiO 2powder, 0.2 ~ 0.5 part of micron order Al 2o 3powder and 0.5 ~ 2 part of silane coupling agent add in the first solvent and carry out ultrasonication and obtain pre-dispersed liquid;
Step 2. is by 2 ~ 3 parts of nano level SiO 2powder, 1.2 ~ 1.8 parts of nano level Al 2o 3powder and isocyanic ester 0.6 ~ 1 part add in pre-dispersed liquid carry out ultrasonication obtain modulation after pre-dispersed liquid;
Methyl methacrylate 70 ~ 80 parts, ethyl propenoate 25 ~ 38 parts and dimethyldiethoxysilane 15 ~ 18 parts add in the second solvent by step 3. carries out mechanical stirring acquisition polymers soln;
The mixing of the polymers soln of pre-dispersed liquid, step 3 after the modulation of step 2 is also added Gum Rosin 4 ~ 6 parts by step 4. successively, note olefine resin 3 ~ 6 parts, azo-compound 1 ~ 1.5 part, N-nitroso compound 4 ~ 6 parts, carry out mechanical high-speed stirring and ultrasonic stirring, thus obtain described pressure-sensitive adhesive.
The technical scheme improved further in technique scheme is as follows:
1. in such scheme, described Nano-meter SiO_2 2powder mean diameter is 12nm, described nanometer Al2O 3powder is on average 30nm so far.
2., in such scheme, described silane coupling agent chemical formula is: CH 2=CH-Si(OC 2h 5) 3.
Because technique scheme is used, the present invention compared with prior art has following advantages and effect:
1. the present invention is used for the protective membrane of electronic product screen, and it adopts nano level and micron order SiO 2powder, Al 2o 3powder and methyl methacrylate, ethyl propenoate, dimethyldiethoxysilane and silane coupling agent, isocyanic ester acting in conjunction, relatively single use nano level or micron order SiO 2powder, Al 2o 3powder, improves vinylformic acid sizing agent roughness, is also conducive to SiO 2powder, Al 2o 3powder is uniformly distributed and dispersion in system, avoids cluster; Secondly, azo-compound part, adding of N-nitroso compound, it also avoid SiO 2powder, Al 2o 3the sedimentation of powder in system, improves and base material bonding force.
2. the present invention is used for the protective membrane of electronic product screen, and Gum Rosin, note olefine resin and methyl methacrylate, ethyl propenoate, dimethyldiethoxysilane acting in conjunction, avoids knowing clearly by SiO 2powder, Al 2o 3powder adds the decline of the resistance to elevated temperatures caused, and improves resistance to elevated temperatures, and the stability of viscosity under difference variation, thus improves the reliability of product.
