| 摘 要： | 研究了甲基丙烯酸甲酯(MMA)和三水合氧化铝(ATH)含量对聚氨酯甲基丙烯酸酯(UM)树脂性能的影响,比较了不饱和聚酯(UP)树脂、乙烯基(VE)树脂和UM树脂的固化反应活性。结果表明,MMA和ATH含量对UM树脂的粘度、固化反应活性、力学性能、硬度和阻燃性能均有显著影响;用DTA法测得UM树脂、UP树脂、VE树脂的表观固化反应活化能分别为45.5kJ/mol、56.7kJ/mol和75.8J/mol。证实UM树脂比UP和VE树脂具有更高的固化反应活性。

| Abstract: | The effects of MMA and alumina trihydrate (ATH) on properties of oligourethane methacrylate (UM) resins were investigated. And the curing reactivities of unsaturated polyester (UP) resin, vinyl ester (VE) and UM resin were compared by various methods. The results show that the effects of MMA and ATH on viscosity, curing reactivity, mechanical properties, hardness, and flame resistance of UM resin are obvious. The apparent values of the curing activation energy of UM resin, UP resin and VE resin are obtained by DAT method. The results are as follows: 45.5 kJ/mol, 56.7 kJ/mol and 75.8 kJ/mol respectively. Experimental results are confirmed that the curing reactivity of UM resin is higher than UP and VE resin. |
