Abstract

The invention discloses a pressure sensitive adhesive, a preparation method thereof and protective films using same. The formula of the pressure sensitive adhesive comprises 20 to 30 parts of butyl methacrylate, 20 to 30 parts of 2-ethylhexyl acrylate, 5 to 10 parts of methyl methacrylate, 2 to 5 parts of hydroxypropyl acrylate, 0 to 15parts of silicon-modified acrylic resin, 0 to 1 parts of trimethylol propyl triacrylate or 0 to 1 part of polyethylene glycol diacrylate, 0.2 to 5.0 parts of polyether-modified polyisocyanate and 50 to 60 parts of ester solvent. The pressure sensitive adhesive is coated on a PE or PP protective film substrate for manufacturing the protective films of optical thin films. The protective films can be directly used for processing raw films of the optical thin films, functional optical films, backlight modules and liquid crystal displayers. The protective films can protect the optical thin films from being polluted and scraped by dust and avoid damaging the intrinsic optical property of the optical thin films.
