| 摘 要： | 为改善双马来酰亚胺树脂(BMI)脆性过大、耐热性不足的缺点，以末端含有氨基的纳米SiO2(SiO2-NH2)为原料，通过溶剂法制备出结构中含有SiO2的苯并噁嗪树脂单体(SiO2-BOZ)，作为改性体系加入到BMI中进行共混，制备出一种耐热性能、韧性良好的新型SiO2-BOZ/BMI树脂材料，并详细研究了SiO2-NH2的添加对BMI固化反应动力学的影响。结果表明，当SiO2-BOZ添加量达到15.0wt%时，SiO2-BOZ/BMI树脂复合材料的表观活化能较纯BMI树脂得到了一定程度的降低，SiO2-BOZ/BMI的弯曲强度达到最大值166.12 MPa，较纯BMI 增加了32.3%，且具有比BMI更好的耐热性能。

| Abstract: | To overcome the excessive brittleness and lower thermal resistant of bismaleimide resins, the silicon dioxide with amino terminal groups(SiO2-NH2) was chosen as raw materials to prepare benzoxazine monomer containing SiO2(SiO2-BOZ). The SiO2-BOZ was then used as the modified system to modify bismaleimide(BMI), aiming to obtain a kind of new SiO2-BOZ/BMI composites with better processability and heat-resistant properties,while the influence of addition of SiO2-BOZ on curing reaction kinetics of BMI was also studied. The results show that when the content of SiO2-BOZ reaches 15.0 wt%, the apparent activation energy of SiO2-BOZ/BMI resin is reduced to a certain extent compared with that of pure BMI resin, and the bending strength of SiO2-BOZ/BMI reaches a maximum of 166.12 MPa, which is 32.3% higher than that of pure BMI, the SiO2-BOZ/BMI also possesses better heat resistance than that of BMI. |
