| 摘 要： | 采用两步法由二元醇、二元酸酐和甲苯二异氰酸酯(TDI)合成了一种不饱和聚酯型聚氨酯(UPPU)。第一步由二元醇和二元酸酐合成出以-OH封端的不饱和聚酯(UP);第二步利用UP的-OH与TDI的-NCO的高反应活性由UP与TDI合成UPPU。同时研究了反应温度、反应时间、原料配比等对UPPU涂膜性能的影响。结果表明,当乙二醇:邻苯二甲酸酐:顺丁烯二酸酐摩尔比为1.2:0.7:0.3,反应温度为205℃,反应时间8h,酸值在40mgKOH/g以下时,得到UPPU涂膜性能较好,硬度6H,附着力1级,柔韧性0.5mm,抗冲击性35cm。 |

| Abstract: | An unsaturated polyester/polyurethane(UPPU) was synthesized by two steps,from di-alcohol,di-anhydride and toluene-2,4-di-iso-cyanate(TDI).The effect of reaction temperature,reaction time and material proportion on properties of UPPU coating was studied.The test results show that the coating was excellent,hardness(6H),adhesion(1),flexility(0.5mm) and resistance to impulsion(35cm) while the proper reaction conditions were the molar ratio of ethylene glycol to phthalandione to maleic anhydride is 1.2:0.7:0.3,r... |
