摘　　要：通过熔融共混法和超分散技术制备了氧化锆改性聚氨酯基复合材料,研究了氧化锆的加入对复合材料的微相结构、摩擦性能及阻尼性能的影响。结果表明,氧化锆粒子的加入可以使复合材料微相分离程度增加,从而使材料阻尼温域显著增加,材料的摩擦去除率也随之提升。当氧化锆质量分数达到3.0%时,材料的阻尼温域达到69℃,与纯聚合物基体相比去除率提升了19.5%,且抛光稳定性良好。Zirconia modified polyurethane matrix composite were prepared by melt blending and hyperdispersion technology, and the effects of zirconia on the microstructure, friction and damping properties of the composites were studied.The results show that the addition of zirconia particles can increase the degree of microphase separation of the composite, and the effective damping temperature range and friction removal rate of the composites also increase significantly.When the content of zirconia reaches 3.0%,the effective damping temperature range of the composite is broadened to 69 ℃,the removal rate is increased by 19.5%comparing with the pure polymer matrix, and the perfect polishing stability can be obtained.
