Abstract
Disclosed is a manufacturing method of polarizer release film automatic peeling adhesive belt, which uses PET film or BOPP film as the substrate; the adhesive layer is composed of pieces of cut rubber mixed by natural rubber and synthesized rubber; part by weight, 100 portions of rubber is taken as the reference, 100 portions of rubber, 30-100 portions of acrylic ester monomers, 5-20 portions of anti-aging agent, 10-20 portions of solvent oil and methyl benzene are melted together for reaction after the temperature is increased; and then 50-100 portions of tackifying resin, 5-10 portions of curing agent are added to the mixture after the mixture is cooled to the normal temperature, and then the mixture is stirred and filtered; the pressure-sensitive adhesive prepared by the adhesive solution is coated evenly on the BOPP or PET through the doctor coating method; the temperature of the coating process is controlled to be under 90 DEG C to 150 DEG C and the coating process is maintained for 3 min to 15 min. the adhesive belt prepared by the manufacturing method has the advantages of good weatherability, good solubility resistance, high peeling strength, avoiding the adhesive overflow on the end surface under normal temperature, preventing the residual adhesive on the surface of the adhered object after repeated tearing and adhesion and stable performance.
Description
Technical field: the present invention relates to Thin Film Transistor-LCD, particularly relate to the method for manufacture of the polarizer relase film automatic stripping tape on the Thin Film Transistor-LCD.
Technical background: Polarizer is the main parts size on the Thin Film Transistor-LCD; Need stick Polarizer on liquid-crystalline glasses sheet two sides in its manufacturing processed; Polarizer one side before use is the PET protective membrane; Another side is the PET dicing film, and automatic stripping tape is used for peeling off the PET dicing film on the Polarizer when Polarizer and glass gluing.Present polarizer relase film automatic stripping tape weathering resistance is bad, and anti-dissolubility is bad, and stripping strength is low, and adhesive tape normal temperature lower surface is prone to the glue that overflows, and after repeating to tear subsides, there is cull on the adherend surface, unstable properties.
Summary of the invention: the present invention is exactly the method for manufacture that a kind of polarizer relase film automatic stripping tape will be provided, and it can overcome the problem that present polarizer relase film automatic stripping tape exists well.The objective of the invention is to realize like this, the method for manufacture of polarizer relase film automatic stripping tape is as base material with PET or BOPP film; Glue-line is that tree elastomer and viton (like the stupid rubber of fourth, paracril, SBS, the SIS) rubber after mixing is cut into fragment; By proportioning (is benchmark with 100 parts of rubber): 100 parts of rubber, acrylate monomer 30-100 part, anti-aging agent 5-20 part, solvent oil 10-20 part add the toluene dissolving and heat up 80 ℃-90 ℃, reaction 2h-4h blending and modifying; Add tackifying resin 50-100 part, solidifying agent 5-10 part after being cooled to normal temperature, stir, filter; The pressure-sensitive adhesive that above-mentioned glue is processed adopts the blade coating formula to be coated in equably on BOPP or the PET, and the coating process temperature is controlled under 90 ℃-150 ℃, keeps 3min-15min, promptly processes adhesive tape.The adhesive tape good weatherability that the present invention processes, anti-dissolubility can be good, and stripping strength is high, the excessive glue in adhesive tape normal temperature lower surface, after repeating to tear subsides, the adherend surface is cull not, stable performance.

Description of drawings: Fig. 1 is a process flow sheet of the present invention
Embodiment: the present invention is described further below in conjunction with accompanying drawing;
In the drawings, the method for manufacture of polarizer relase film automatic stripping tape of the present invention is as base material with PET or BOPP film; Glue-line is that tree elastomer and viton (like the stupid rubber of fourth, the paracril etc.) rubber after mixing is cut into fragment; By proportioning (is benchmark with 100 parts of rubber): 100 parts of rubber, acrylate monomer 30-100 part, anti-aging agent 5-20 part, solvent oil 10-20 part add the toluene dissolving and heat up 80 ℃-90 ℃, reaction 2h-4h blending and modifying; Add tackifying resin 50-100 part, solidifying agent 5-10 part after being cooled to normal temperature, stir, filter; The pressure-sensitive adhesive that above-mentioned glue is processed adopts the blade coating formula to be coated in equably on BOPP or the PET, and the coating process temperature is controlled under 90 ℃-150 ℃, keeps 3min-15min, is evenly coated on BOPP or the PET, promptly processes adhesive tape.During practical implementation, selecting the 1Kg tree elastomer for use or adding part styrene-butadiene rubber(SBR) is base-material, it is broken into fritter places the reactor drum that has chuck and whisking appliance; Add toluene 3Kg successively, TEB 3K 300g, vinylformic acid 50g; Lucidol 5g; Solvent oil 10g is warming up to 85 ℃, reaction 3h; Fully dissolve to rubber, add terpine resin 800g again, cooling is filtered the back and is added trimeric cyanamide (7110 first, self-control) 40g, allocates an amount of dilution with toluene to suitable coating glue into; Adopt the blade coating formula evenly to be applied on the PET film above-mentioned pressure-sensitive adhesive, the about 30um of thickness, the coating process temperature is controlled under 130 ℃, keeps 3min, oven dry afterwards tape product, carry out rewinding again, cut, pack.
