In order to improve the adhesion of water-based adhesive, gemini type nonionic reactive surfactants were synthesized and applied to water-based adhesives. Gemini type nonionic reactive surfactants were synthesized by using maleic acid and polyoxyethylene cetyl ether having different length of ethylene oxide. The synthesized surfactants were confirmed by FT-IR and 1H-NMR. Their appearance was light yellow wax. The cloud point of the compound was more than 78 ℃. The measured critical micelle concentration(c.m.c) was 1.0×10-4∼7.0×10-4 mol/L and surface tension at c.m.c was 25.9∼32.0 mN/m. As the number of ethylene oxide increased, the emulsifying power was improved. Foaming height of the compound by Ross-Miles method was 1.4∼4.5 cm.
The synthesized surfactants in this research was used as emulsifier in emulsion polymerization of water-based adhesives and its physical properties were evaluated. The solid contents of prepared adhesives 59 %. The average particle size of the prepared adhesives was 164 ∼297 nm. Initial tackiness of prepared adhesives was ball no. 20∼32. The peel strength was 1.8∼2.1 Kgf/mm. The retention rate of adhesives viscosity was evaluated to 99 % during 30 days. So synthesized gemini type nonionic reactive surfactants are expected to be applied as emulsifier for high adhesive force.
