Abstract

In this study, aqueous acrylic emulsion adhesives were prepared using various surfactants and their properties were also investigated. Solids content, conversion, particle size distribution and initial adhesion properties of the prepared adhesives were compared with each other. The solid content of the adhesives was evaluated 60% and the conversion rate of the emulsion polymerization was 97% at 2 wt% concentration of synthesized surfactants. The particle size distribution analysis revealed that the size distribution of adhesive particles was 290~470 nm when the synthesized cationic surfactant was added. The initial adhesion and adhesion time were also improved. The maximum adhesive strength was found to be 2.55 kgf when using a single surfactant (POE 23), and superior to that of using other surfactants. It was confirmed that the corrosion inhibition of the adhesive prepared by adding the cationic gemini surfactant was maintained for 48 hours.
