| 中文摘要: |
| 通过单因素实验和正交实验,以涂膜的拉伸强度为依据,确定了用有机硅和环氧树脂复合改性聚氨酯涂料时,制备聚氨酯预聚体的单体甲苯二异氰酸酯(TDI)和聚醚二元醇(DL2000)的恰当配比,有机硅、环氧树脂和增塑剂的恰当添加量,以及恰当的反应时间和反应温度。对复合改性涂膜进行了红外光谱分析和热重分析,对比检测了未改性涂料、有机硅改性涂料、有机硅和环氧树脂复合改性涂料的各方面性能。结果表明,有机硅和环氧树脂复合改性的聚氨酯涂料各方面性能良好,涂膜具有较高的力学强度、良好的附着力、较低的吸水率、较好的热稳定性和耐酸碱性能。 |

| By single factor experiment and the orthogonal experiment, organosilicon and epoxy resin modified polyurethane coating was prepared.According to the tensile strength of film, the optimum ratio of TDI and DL2000 of polyurethane was determined, appropriate additive quantity for organosilicon, epoxy resin and plasticizer was obtained, included suitable reaction time and reaction temperature. Infrared spectrum analysis and thermogravimetric analysis were tested for compound modification film, comparing various aspects of the performance with unmodified coating, organsilicone-modified coating and organosilicon and epoxy resin modified polyurethane coating. The result shows that organosilicon and epoxy resin modified polyurethane coating has high strength and adhesion force, low water adsorption rate, high thermal stability and corrosive acid and base resistance. |
