摘　　要：磁性光整磨具由基体(载体和辅助添加剂)、磁介质相和磨粒相组成,在磁场中能更好地发挥磨具的自适应性,有利于解决细长管、窄槽(键槽、油沟等)、曲面等异型表面光整加工的实际生产难题。载体选用低粘度硅胶、PVC和PVC糊树脂,根据其不同特性利用相应机理制得基体,然后通过一定工艺方法制得磁性光整磨具。对载体的性能(流动性、导热性、腐蚀性、分散性和环保方面)分析,表明PVC糊树脂载体制备的磨具的综合性能要优于低粘度硅胶和PVC,为进一步研究和提高磨具的性能奠定了基础。Magnetic finishing abrasive is composed of matrix （carrier and auxiliary additive）, magnetic medium and abrasive particle phase. In magnetic field, magnetic finishing abrasive can exert its adaptability better and be conducive to solve the finishing processing problems existing in elongated tubes, narrow slots （ keyway, oil groove, etc. ）, curved surfaces and other special-shaped surfaces in the practical production. Respectively,low viscosity silicone rubber, PVC and PVC paste resin are used as carriers of matrixes. According to their different characteristics, and based on relevant mechanisms magnetic finishing abrasives are prepared. Based on analysis of the carriers’ performances including mobility, thermal conductivity, causticity, dispersion and environmental protection, the result shows that the comprehensive performance of PVC paste resin as abrasive carrier is better than that of low viscosity silicone rubber and PVC, providing a reference for further studying and improving the performance of this kind of abrasive.
