Description

A kind of containing APCF layer polaroid two-sided shading rubber belt and preparation method thereof
Technical field
The present invention relates to adhesive tape field, particularly relate to a kind of containing APFC layer polaroid two-sided shading rubber belt and preparation method thereof.
Background technology
Display panels (LiquidCrystalDisplay, LCD) there is the advantages such as high image quality, low-work voltage, low consumpting power, Low emissivity, light weight, therefore the electronicss such as portable TV, mobile telephone, computer display screen, counter are applied to by wide model, and progressively replace cathode tube (CRT), become the main flow of indicating meter.Traditional liquid-crystal display framework mainly comprises housing, liquid crystal panel, circuit card and backlight module, and backlight module generally comprises several parts such as support, reflector plate, light guiding plate, blooming.Generally speaking, display panels on the market and the assembling of backlight module, shading rubber belt is often adopted to be attached at the edge of liquid crystal panel and backlight module, make not easily to produce displacement between liquid crystal panel and backlight module, thus prevent from occurring friction between display panels and backlight module, avoid the blooming piece of scratch backlight module, guaranteed the display quality of display panels.In addition, shading rubber belt can also cover the unnecessary light sent from liquid crystal panel, in case leak-stopping light.
In practical combinations process, liquid crystal display and backlight module often have laminating shifting phenomena, need again to peel off to fit again.Universal along with what apply in liquid crystal display containing APCF layer polaroid, common shading rubber belt has the performance be permanently fixed, its initial stage clinging power is often higher, directly paste APCF layer, easily damage APCF layer or residual colloid when peeling off on APCF, causing that liquid crystal display imaging effect is not good even cannot imaging again.
Summary of the invention
First technical problem to be solved by this invention provides a kind of to containing when APFC layer polaroid is peeled off again without the vinylformic acid Adhesive composition that cull, nothing are damaged.
Second technical problem to be solved by this invention provides a kind of containing the two-sided shading rubber belt of APFC layer polaroid, this adhesive tape can not only be permanently fixed liquid crystal display and backlight module, and damages without cull, nothing when peeling off containing APFC layer polaroid again.
3rd technical problem to be solved by this invention is the preparation method providing a kind of above-mentioned two-sided shading rubber belt for prior art.
The present invention solves the technical scheme that first technical problem adopt: a kind of heavy industry type has the vinylformic acid Adhesive composition of UV activity, it is characterized in that, it is made up of following component and mass fraction thereof:
Its molecular weight of multipolymer that described oligopolymer and acrylate monomer copolymerization are formed is 10 ~ 1,000,000, dispersity Mw/Mn is 3 ~ 10, and wherein said oligopolymer is the combination of one or more in unsaturated polyester, carbamate, acrylate, urethane acrylate, epoxy acrylate, polyester acrylate; Described acrylate monomer is the combination of one or more of tripropylene glycol diacrylate, tetrahydrofurfuryl acrylate THFA, 2-phenoxyethyl acrylate, ethoxyethoxyethyl acrylate; Described toughner is the one or more combination in polymeric amide, phthalic acid ester or acrylic elastomer.
