摘　　要：用UMT-2MT摩擦试验机测试了9种常用实木地板对橡胶和440C不锈钢的摩擦磨损性能.结果表明:橡胶对多数地板的摩擦系数大于0.5,满足安全标准,且均大于钢球对地板的摩擦系数.钢球对地板漆层的摩擦系数介于0.1～0.6之间,而钢球对地板木材的摩擦系数基本相同,处于0.55左右.橡胶对地板磨损试验未能得到可测的磨损量(试验时间为1 h).钢球对地板漆层和木材层的磨损不同,漆层的抗磨损能力普遍高于木质层.每种地板都有临界载荷,载荷小于临界载荷时,随着载荷的增加磨损量几乎不变;载荷大于临界载荷后,随着载荷的增加磨损明显加快.The friction and wear properties of nine kinds of typical solid wood floorings were investigated using the tribometer of UMT -2MT. The coefficients of friction （COFs） between rubber shoe sole and floor were much higher than that between stainless steel ball and floor. For the nine different solid wood floorings, the COFs between stainless steel ball and lacquer for floor varied significantly from 0.1 to 0.6, while the COFs between stainless steel and solid wood of floors were nearly a constant around 0.55. The wear of floors was un - detectable when rubber shoe sole was experimented with floor for one hour. As stainless steel ball rubbed on the floorings, the anti - wear properties of lacquer for floors were better than that of solid wood. And a critical loading for each floorings was set up. As loads were lower than the critical one, the wear of floors was negligible, while higher than the critical load, the wear was much higher and increased quickly with increasing load. The experiments raise a possibility to evaluate the anti - wear properties of lacquer for floor and how to protect the floors from early wear by using right shoes.
