実験手順

248.2 g of IPDI was slowly dropped into a mixture of 600 g of polytetramethylene ether glycol (PTMEG-1000) and 35 g of DMPA in a four-necked bottle equipped with a condensation tube. The resulting mixture was heated to 100° C. by heating mantle and was stirred for 3 hours by machine. After being cooled to 60° C., the mixture was diluted with 500 mL of acetone and then cooled to room temperature to obtain PTMEG/DMPA/IPDI/acetone type of aqueous polyurethane prepolymer. 100 g of said aqueous polyurethane prepolymer was put into a 250 mL beaker and stirred by machine. One drop of Triethylamine (TEA) was added inside as neutralizer. After continually stirring for 10 minutes, the well-mixed solution was dropped slowly into water, which was stirred at high speed (the amount of the water can be adjusted as requested). After dropping all the solution, the aqueous polyurethane prepolymer was dispersed uniformly into the water by continually stirring at high speed for 20 minutes. Then, acetone was withdrawn by using decompression concentrator to obtain aqueous polyurethane dispersion 2 with various solid contents.
