摘　　要：用丙烯海松酸聚酯多元醇(AAPP)、聚醚N-210及甲苯二异氰酸酯为原料,合成了丙烯海松酸型水性聚氨酯(AAWP),对所得产品进行了红外光谱、热失重、镜面光泽、摆杆硬度、耐冲击强度、附着力、柔韧性、耐水性测试和表征。结果表明:当丙烯海松酸聚酯多元醇的加入量为丙烯海松酸聚酯多元醇与聚醚N-210总质量的40%时,产品的综合性能优良,分别达到:镜面光泽为131.6,摆杆硬度为0.80,耐冲击强度为80 kg.cm,热失重5%时的温度260.3℃,耐水性合格,柔韧性为0.5 mm,附着力1级。Acrylpimaric acid-based waterborne polyurethane （AAWP） was prepared from acrylpimaric acid polyester polyols （AAPP）, polyether glycol （N-210） and toluene diisocyanate. The properties of the products were characterized by FT-IR spectra, thermogravimetric analysis （TGA）, testings on specular glossiness, pendulum hardness, impact strength, adhesion, flexibility and water-resistance. The results indicated that when the dosage of acrylpimaric acid polyester polyols is 40 % （relative to total weight of acrylpimaric acid polyester polyols and polyether glycol ）, acrylpimaric acid-based waterborne polyurethane has good performances with specular glossiness of 131.6, pendulum hardness of 0.80, impact resistance of 80 kg·cm, 5 % weight-loss temperatures of 260.3 ℃ , adhesion of the first grade and flexibility of 0.5 mm.
