中文摘要:
      采用超声波辅助混合手段，制备中空玻璃微珠（HGB）/蓖麻油基聚氨酯脲复合材料，并对其性能进行探讨。结果表明：当HGB用量为15份时，复合材料物理性能较好；HGB的加入提高了聚氨酯弹性体第二热降解阶段的热降解温度；HGB的增韧机理以其阻止裂纹继续扩展和聚氨酯的“海-岛结构”为主。
英文摘要:
      The hollow glass bead（HGB）/polyurethane-urea（PUU） composite was prepared by ultrasonic wave assistant mixing way，and the properties of the composites were studied.The results showed that，when the addition level of HGB was 15 phr，the physical properties of HGB/PUU composite were better.The second stage thermal decomposition temperature of the composite was increased after adding HGB. The experimental results also indicated that both the crack growth prevention of the HGB and “sea-island structure” of PU were the main toughening mechanism of HGB toughened PUU.
