Abstract

The invention relates to a heavy industry type acrylic acid adhesive composition with UV activity, which is prepared from the following components in parts by mass: 100 parts of copolymer formed by a low polymer and an acrylate monomer through copolymerization, 4 to 10 parts of photoinitiator, 0.5 to 0.8 part of first cross-linking agent and 1 to 2 parts of flexibilizer; the invention also relates to a double-sided shading tape for a polaroid containing an APCF layer which applies the adhesive composition and a preparation method of the double-sided shading tape. Compared with the prior art, the double-sided shading tape provided by the invention not only can permanently fix a liquid crystal display screen and a backlight module, but also has no adhesive residues and no damage to the polaroid containing the APCF layer which is stripped again within 48h under the observation of a microscope with 200 times, the tape preparation method is simple, and by applying the tape provided by the invention, the reject ratio of novel polaroids in a using process can be obviously reduced, and the heavy industry working efficiency is improved.

Description

technical field [0001] The invention relates to the field of adhesive tapes, in particular to a double-sided light-shielding adhesive tape for a polarizer containing an APFC layer and a preparation method thereof. Background technique [0002] Liquid Crystal Display (LCD) has the advantages of high image quality, low operating voltage, low power consumption, low radiation, light weight, etc., so it is widely used in portable TVs, mobile phones, computer monitors, calculators, etc. Electronic equipment, and gradually replace the cathode ray tube (CRT), become the mainstream of the display. The structure of a traditional liquid crystal display mainly includes an outer frame, a liquid crystal panel, a circuit board, and a backlight module. The backlight module generally includes several parts such as a bracket, a reflector, a light guide plate, and an optical film. Generally speaking, in the assembly of LCD panels and backlight modules on the market, light-shielding tapes are ...
