Preparation of Cationic Water-based Polyurethane Emulsion
阳离子型水性聚氨酯乳液的合成

A water-based cationic polyurethane emulsion was prepared. This emulsion was mainly composed of polyester glycol, trimethylol propane, toluene diisocyanate (TDI) and N-methyl-diethanolamine. The influences of the reaction temperature, content of each agent and stirring speed on the mechanical properties of the water-based polyurethane were investigated, giving its optimum composition. The polyurethane emulsion with good performance was prepared. And mechanical properties of the product are very good.
