ABSTRACT

This study worked on the synthesis of waterborne polyurethane/epoxy hybrid resins containing aminosilane compound to replace conventional phenol resins used for a coating material for loudspeaker dampers, which are not harmful to human being. Waterborne polyurethane resins were synthesized from two diisocyanate of 4,4'- diphenylethane diisocyanate and toluene diisocyanate, two polyols of polyester polyols(PEP), polycarbonatediol(PCD), including and anionic center of dimethylol butanoic acid, a chain extenders of ethylenediamine(EDA), and a neutral agent of triethylamine. Synthesized polyurethane resins and commercially available bisphenol A type waterborne epoxy resin were blended in weight ratios of 80:20 to prepare polyurethane/epoxy hybrid resins. The synthesized waterborne polyurethane/epoxy hybrid resins were reacted with aminosilane compound to improve mechanical properties. Aminosilane-treated polyurethane/epoxy hybrid resins showed better mechanical properties.
