摘　　要：油田管道腐蚀和结垢造成了巨大的损失,防腐、防结垢比较困难,而且涂料在热镀锌管上难以附着,为此进行了大量的研究工作,首先,通过合成固化剂,解决了涂料在热镀锌管上附着力差的问题;其次,合理选用颜填料以及纳米S iO2和纳米TiO2,同时选用有效降低表面张力的助剂,使表面结垢得到了比较好的控制。另外,通过控制混合溶剂的挥发速率,使产品能较好地适应长管道、小直径的特殊施工工艺及设备,并使产品施工固体分高,施工产生的漆雾少,具有很好的环保性能。In view of the significant loss by the heavy corrosion and scaling of the pipe linings in oil fields,especially poor adhesion on hot-dipping galvanized pipes,a great number of concerns have been paid on development of new technology.A new curing agent is developed to solve the poor adhesion on hot-dipping galvanized pipes;careful selection of pigments and fillers and utilization of nano SiO_(2) and TiO_(2) and additives that will reduce the surface tension enable better control of the scaling on linings;adjustment of evaporation rate of the blended solvent can improve the applicability of coatings,by use of special application facilities,on pipes with small diameter and long length;and high solid of the coatings will reduce the spray mist and provide food environmental protection performance.
