采用一步法合成聚氨酯,控制超细氧化铈的加入比例,用热重法和机械性能测试分析了聚氨酯的热稳定性和机械性能。结果显示,与普通聚氨酯相比,加入超细氧化铈后聚氨酯的耐热性能明显提高。
Polyurethane was synthesized by one-step method to control the adding proportion of ultra-fine cerium oxide. The thermal stability and mechanical properties of polyurethane were analyzed by thermogravimetric method and mechanical property test. The results show that, compared with ordinary polyurethane, the heat resistance of polyurethane increases significantly after adding ultra-fine cerium oxide.
