摘　　要：采用一次成膜和程序升温法,制备了以聚酰亚胺为基底的氧化铝新型磨片(Al2O3/PI),可用于硬脆性机件表面的精加工和抛光。扫描电镜(SEM)显示,Al2O3/PI磨片为双层膜型,磨料层厚度约50μm,基底厚度约150μm。差热分析(DSC/TGA)、拉伸强度和断裂伸长率测试表明显示,Al2O3/PI磨片的热分解温度大于500℃,并具有PI膜的高强度和良好的柔韧性。对磨片制备过程的主要影响因素及铜片的抛光效果进行了讨论。By using the method of the procedure heat and once filming, a new grinding material of Al2O3/PI was prepared. This grinding material can be used into polishing of the firm and brittle material. Scanning electron microscope （SEM） showed that Al2O3/PI was a double-layer-film, The top-layer full of Al2O3 was about 50μm thick. The under-layer which was PI was about 150μm thick. DSC/TG data and tension test displayed that Al2O3/PI grinding slice maintained the excellent properties of PI. The preparation process and polished effect of sheet copper were also discussed.
