The invention discloses an emulsion polymerization pressure-sensitive adhesive with ultra-low emulsifier dosage and high water resistance and weather resistance. It is composed of four categories of components: unsaturated monomer, water, emulsifier and water-soluble initiator. The unsaturated monomer includes but is not limited to: acrylic acid, methacrylic acid, methyl methacrylate, styrene, vinyl acetate , one or more of butyl acrylate, isooctyl acrylate, acrylamide, and N-methacrylamide. The present invention uses the polymer obtained by the method of emulsion polymerization, so the molecular weight is much higher than that of the oily solution polymerization method, and the performance is also better; The substance is comparable to oily polymers in water resistance. |
