摘　　要：采用添加低表面能填料的方法制备出不同表面性质的环氧涂层,在循环管道试验装置上评价环氧清漆、环氧色漆对3种不同黏度油品的减阻效果。结果表明:环氧清漆、环氧色漆对测试油品均有明显的减阻效果,其中添加低表面能填料的环氧色漆减阻效果较好;在雷诺数为3475时,3%PTFE环氧色漆涂层对3号油品的最大减阻率达到23.1%;涂层对油品的减阻效果与油品黏度和涂层表面性能有关,油品的黏度越大,涂层的表面张力越小,涂层对油品的减阻效果越明显。<正>Pipeline wall with resin coating can significantly reduce the resistance of its delivery. Epoxy coatings with various surface properties were prepared by adding different amounts of low surface energy filler. The drag reduction effect of epoxy varnish and epoxy color paints was evaluated in a circulation pipeline testing equipment in the laboratory using three oil samples having various viscosities. Results show that all the prepared coatings exhibit drag reduction function on the samples tested, and coatings containing low surface energy filler have better drag reduction effect,in which epoxy color paint with 3 ~ PTFE shows the maximum drag reduction rate of 23.1% at a Reynolds number of 3 475. However,the drag reduction effect of epoxy coatings on oil samples is related to the oil viscosity and the surface property of coating,with the increase of oil viscosity and the decrease of coating surface tension, the drag reduction rate of coating increases.
