在UMT?2型微摩擦试验机上分别测定邻苯二甲酸二异丁酯、邻苯二甲酸二正戊酯、邻苯二甲酸二正辛酯、邻苯二甲酸二异辛酯、邻苯二甲酸二壬酯、邻苯二甲酸二异癸酯在5～98 N载荷下的摩擦学性能。实验结果表明：在不同的载荷下，随着试验时间的延长，6种酯的摩擦因数都呈现下降趋势；邻苯二甲酸二异癸酯平均摩擦因数在各载荷下都最小，但是在低载荷下（5 N左右）波动较大；同一载荷下，直链酯的平均摩擦因数随着碳链长度的增加而降低，支链酯的平均摩擦因数变化无明显规律；同种酯的磨斑直径随载荷的升高而增加；同一载荷下，不同碳链长度的酯的磨斑直径变化没有明显的变化规律，醇碳链的延长并不能有效地控制磨损。

The tribological performances of diisobutyl phthalate, dipentyl phthalate, di?n?octyl phthalate, di ( 2?ethyl?hexyl) phthalate, dinonyl phthalate, and diisodecyl phthalate were investigated under the loads form 5 N to 98 N. The re?sults show that the friction coefficients of the six esters tend to decrease with the increasing of the time at the different loads. Among the six phthalate esters, diisodecyl phthalate shows the lowest friction coefficient under the all loads, howev?er whose friction coefficient is changed greatly under the low loads( about 5 N) . Under the same loads, the average friction coefficients of straight chain esters is decreased with the increasing of the carbon chain length, however the branched chain esters present different trend. The wear scar diameter of the esters is increased with the increasing of the loads. Under the same loads, the wear scar diameter of the different esters show no obvious change rule, indicating the extension of carbon chain length cannot contribute to reduce the wear scar diameter.
