The invention relates to emulsion pressure-sensitive adhesive which has better plasticizer transport resistance and is applied to the manufacturing of soft polyvinyl chloride (SPVC) electric gluing belt. The emulsion pressure-sensitive adhesive is made by co-mixing specially synthesized acrylate copolymer emulsion and other resin emulsion and/or rubber latex. Special soft monomers and special functional monomers are adopted in the acrylate copolymer emulsion synthesis formulation. And a Core-Shell emulsion copolymerization method is adopted in the acrylate copolymer emulsion synthesis technology.
