| Abstract: | A series of polyurethane prepolymer were prepared with IPDI and PCL1000.The propolymer reacted with acrylate and styrene to gain the acrylate-polyurethane hybrid emulsion.The influences of NCO/OH,the dosage of styrene and the species of acrylate on solvent-resistance,water-resistance,heat-resistance and weatherability were discussed,with the characterization of PUA films' swelling rate,water contact angle and running of TG and UV weathering test.The results indicated that the integrative property of PUA fil... |
