Zusammenfassung:PURPOSE:To obtain an epoxy resin emulsion adhesive composition having low viscosity and good workability, being capable of long-term storage, and retaining the inherent excellent properties by mixing a liquid epoxy resin with a high- molecular water-soluble polyamine and water. CONSTITUTION:This composition is an oil-in-water epoxy resin emulsion adhesive composition prepared by mixing 100 pts.wt. liquid epoxy resin with 20-50 pts.wt. high-molecular water-soluble polyamine and 10-80 pts.wt. water. This composition may optionally contain 0.5-10 pts.wt. water-soluble polymer and/or 5-20 pts.wt. cure accelerating aid. In order to reduce the viscosity of the epoxy resin, it is also possible to add at most 20 pts.wt. reactive diluent such as phenyl glycidyl ether or inert diluent such as dibutyl phthalate to 100 pts.wt. epoxy resin.
