Synthesis and characterization of water based acrylic Pressure sensitive adhesive of surface protection tape

摘要

The water based acrylic pressure sensitive adhesive was synthesized by seeded pre-emulsion polymerization, the influence of the amount of seeded pre-emulsion, and tri-functional aziridine crosslinker on the properties of the adhesive were studied. It was found that with the increase of the amount of seeded pre-emulsion, latex particle size decreases, contrasted with the increase of the viscosity, surface tension and contact angle of the emulsion;;The aging performance of the adhesive can be significantly improved with the increase of the content of the crosslinker;;compared with high temperature, high humidity has a more worse negative effect on the aging performance of the adhesive.
