WATER-SOLUBLE EPOXY RESIN WITH EXCELLENT WATER UPTAKE AND WATER RETENTIONABILITY, A MANUFACTURING METHOD THEREOF AND A BLOCK INCLUDING THE SAME

摘要

PURPOSE: A water-soluble epoxy resin with excellent water uptake and water retentionability, a manufacturing method thereof and a block including the same are provided to discharge moisture slower.;CONSTITUTION: A water-soluble epoxy resin is manufactured by reacting polyether glycol with epichlorohydrin. The polyether glycol is polyethylene glycol. The polyethylene glycol and epichlorohydrin react at the weight ratio of 82-86 : 8-10. A water-soluble epoxy resin composition comprises the water-soluble epoxy resin manufactured by reacting polyether glycol with epichlorohydrin; one or more curing agents selected from water-soluble amines and polyimine, one or more additives selected from a group] consisting of antifoaming agent, leveling agent, a viscosity modifier and an antioxidant.;COPYRIGHT KIPO 2013
