白炭黑/浇注型PU复合材料的性能研究Keywords: [浇注型PU,白炭黑,原位聚合,补强, 浇注型PU,白炭黑,原位聚合,补强,cast PU,silica,in-situ polymerization,reinforcement] Abstract: 采用原位聚合法制备白炭黑/浇注型PU复合材料，研究炭黑品种对复合材料性能的影响。试验结果表明，亲水型的白炭黑AEROSIL 200和疏水型的白炭黑AEROSIL R972在聚己内酯二醇（PCL）中的分散性和稳定性较好，对PCL浇注型PU复合材料有显著补强、增韧和提高材料高温使用性能的作用。;The effects of the silica type on the properties of silica/cast PU composites prepared by insitu polymerization were investigated.The test results showed that the dispersibility and stability of hydrophilic silica AEROSIL 200 and hydrophobic silica AEROSIL R972 in poly（ε-caprolactone） （PCL） were better；they could be used to strengthen and toughen silica/cast PU composites and improve the high temperature performance of the composites
