Abstract

The invention provides a protection film used on display screens. The protection film comprises a film base material layer, wherein the lower surface of the film base material layer is bonded with a release film by a pressure sensitive adhesive layer; the pressure sensitive adhesive layer comprises the following components in parts by weight: 80 parts of methyl methacrylate, 35 parts of ethyl acrylate, dimethyldiethoxysilane, solvents, nano SiO2 powder, nano Al2O3 powder, micron SiO2 powder, micron Al2O3 powder, isocyanate, rosin resin, terpene resin, an azo compound, an N-nitroso compound and a coupling agent. The protection film has the advantages that sedimentation of the SiO2 powder and the Al2O3 powder in a system is avoided; the adhesion with a base material is improved.

Description

Display screen protection pad pasting
Technical field
The present invention relates to a kind of protective membrane, particularly a kind of display screen protection pad pasting.
Background technology
Acrylic ester adhesive is that a class is using the esters monomer containing acrylic or methacrylic acid building stone as body material, adding solidifying agent, initiator, promotor and facilitate fast setting by coordinating, just can reach the thermoset structure tackiness agent of certain bonding strength and adhesive effect in a short time.In order to avoid electronic product screen surface is subject to scratch or wearing and tearing, affect result of use, generally can paste screen protecting film in the screen surface of electronic product.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 display screen protection pad pasting, this protection pad pasting 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 display screen protection pad pasting, and described protection pad pasting comprises a thin film based sheet material layers, and this thin film based sheet material layers lower surface is by formation of pressure-sensitive adhesive layer and a release film adhering junction;
Described formation of pressure-sensitive adhesive layer is made up of following parts by weight of component: methyl methacrylate 80 parts, ethyl propenoate 35 parts, dimethyldiethoxysilane 16 parts, solvent 41 parts, nano level SiO 2powder 3 parts, nano level Al 2o 3powder 1.4 parts, micron order SiO 2powder 0.25 part, micron order Al 2o 3powder 0.3 part, isocyanic ester 1 part, Gum Rosin 5 parts, terpine resin 4 parts, azo-compound 1.4 parts, N-nitroso compound 6 parts, coupling agent 1 part.
The technical scheme improved further in technique scheme is as follows:
In such scheme, described solvent is at least one in toluene, ethyl acetate and butanone.
Because technique scheme is used, the present invention compared with prior art has following advantages and effect:
1. display screen protection pad pasting of the present invention, it adopts nano level and micron order SiO 2powder, Al 2o 3powder and methyl methacrylate 80 parts, ethyl propenoate 35 parts, dimethyldiethoxysilane 16 parts 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 1.4 parts, adding of N-nitroso compound 6 parts, it also avoid SiO 2powder, Al 2o 3the sedimentation of powder in system, improves and base material bonding force.
2. display screen protection pad pasting of the present invention, it comprises Gum Rosin 5 parts, and terpine resin 4 parts and methyl methacrylate 80 parts, ethyl propenoate 35 parts, dimethyldiethoxysilane 16 parts of actings in conjunction, avoid 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.
Embodiment
