纳米磨料制备花岗石抛光磨具的研究

STUDY ON THE PREPARATION OF GRANITE POLISHING TOOLS WITH NANOSIZED ABRASIVE GRITS

以纳米三氧化二铝和纳米二氧化锡等作为复合纳米磨料 ,以酚醛树脂为粘结剂在 160℃和 8MPa的条件下预压 ,然后在硬化炉里硬化制备花岗石抛光磨具。磨削对比试验表明 :纳米磨料花岗石抛光磨具的磨削性能、耐磨性能、耐水性能均优于普通磨料花岗石抛光磨具 ,前者的抛光光洁度达

Granite polishing tools were prepared with nanomaterials(mixture of nano Al 2O 3 and nano SnO 2) as abrasive grits, phenolic resin as binder, pre pressed at 160℃ and 8MPa and then hardened in the hardening oven. The polishing experiment showed that the characteristics of nano abrasives granite polishing tools such as grinding performance, erosion resistance and water impermeability are higher than that of the conventional granite polishing tools. The polishing finish can attain to 98 0.
