制备了粉煤灰微珠/环氧树脂复合材料,并利用磨耗仪和邵氏硬度计测试了涂层试样的磨耗量和硬度。通过分析磨损表面微观形貌,探讨了固化工艺、固化剂和微珠添加量等对涂层试样磨耗性能的影响。结果表明,固化剂聚酰胺650的添加量显著影响涂层试样的硬度,当固化剂的含量增加时,涂层试样硬度随之增加,其表现出来的磨耗量也随之减少。试样的磨耗量也随固化工艺的不同而不同,在固化工艺为120℃1 h 时,试样的耐磨耗性能最好。随微珠添加量的增加,试样的磨耗量呈现先减少后增加的趋势,当粉煤灰微珠质量分数为20%时,试样的磨耗性能最好。

Epoxy resin composite filled with fly ash cenospheres were synthesized.The abrasion loss and hard-ness of specimens were measured using an abrasion tester and a Shore hardness tester,respectively.And the effect of curing process,curing agent content and cenospheres content on abrasion performance of specimens was discussed by analyzing the micrographs of the worn surfaces.The results show that the amount of polyam-ide 650 obviously affects the hardness of specimens.And with the increase of polyamide 650,the hardness of specimens increases and the abrasion loss decreases.The abrasion loss of specimens are different with the differ-ent curing process.The composite obtained at the curing temperature of 120 ℃ and curing time of 1 h has the better abrasion performance.With the increase of amount of fly ash cenospheres,the abrasion loss of the speci-men decreases first and then increases.When the mass fraction of cenospheres is 20wt%,the composites exhibit the best abrasion performance.
