The invention discloses an emulsion pressure-sensitive adhesive for a polarizer protective film and a polarizer protective film thereof. The pressure-sensitive adhesive is prepared from the following raw materials in parts by weight: 100-200 parts by weight of deionized water, 0.5-1.5 parts by weight of sulfonate-reactive emulsifier, 1-4 parts by weight of quaternary ammonium containing double bonds Salt monomer, 15-40 parts by weight of soft monomer, 5-10 parts by weight of hard monomer, 2-5 parts by weight of functional monomer, 1-4 parts by weight of blocked water-based isocyanate. The pressure-sensitive adhesive of the present invention can be directly coated on the surface of the polyester film without adding an antistatic agent, the resistance of the adhesive layer is below 10 9 Ω, and has antistatic performance. When the adhesive layer of the polarizer protective film of the present invention is attached to the surface of the polarizer, after a high temperature and high temperature and high humidity test for 500 hours, the protective film is closely attached to the polarizer, no bubbles bulge, and no residual glue or shadow is left when the protective film is removed. etc. ills. |
