| Abstract: | Silicane(γ-aminopropyl triethoxysilane(KH550),γ-glycidoxypropyl trimethoxysilane(KH560)) has been utilized to modify waterborne polyurethane(WPU) emulsion,and the change of the adhesive properties after the modification has been investigated.WPU modified by KH560 had higher adhesive ability to the inorganic surfaces.The film’s adhesive abilitiy to the glass plate in dry state could reach 1 level and the adhesive abilitiy to the tin plate could reach 1～2 level.In water state,the film on the glass plate has better adhesive ability of 1～2 level,while in water state,the adhesive ability to the tin plate could remain about 3～4 level. |
