Mixed with traditional emulsifiers of sodium alkyl sulfate and alkyl phenol polyoxyethylene ether as a compound emulsifier, a BGMAH modified acrylate emulsion pressure-sensitive adhesive was prepared by semi-continuous seed emulsion polymerization. Effects of the structure and dosage of BGMAH on the emulsion particle size, water resistance and adhesion property of latex film were investigated. The results showed that when BGMAH accounted for 50% of the total mass of the compound emulsifier, the adhesive property and water resistance of the latex film were best: initial viscosity 14, sticky 36.4h, peel strength 412.3N/m, and water absorption 4.7%. Infrared spectroscopy results showed that the copolymerization crosslinking reaction of acrylic emulsion occurred in the modification process. DSC showed that the modified polymer system had good compatibility and the glass transition temperature of latex film increased from -33.6℃（before modification）to -28.7℃（afte
