摘　　要：通过低热法制备锶铁氧体(strontium ferrite,SF),将其加入到涂层中,研究磁粉不同磁性、添量、添加剂和含水率与防蜡率之间的关系。实验表明:随着磁粉磁性的增强,防蜡率逐渐增大,在850℃下煅烧所制磁粉磁性最强,防蜡率也最佳。磁粉添量为2%,防蜡率最大,达到了77.3%;再向体系中添加0.6%的聚乙二醇后,防蜡率达到80.1%。研究发现,蜡晶分子在磁粉颗粒的磁场作用下产生极化,导致蜡晶分子定向排列,不易聚集,从而使得防蜡率提升。The strontium ferrite （SF）powders were added into alkyd resin varnish,we studied the different magnetic properties and additions of the SF powders,water ratio of the stimulant oil to act on the SF coatings.The results showed the paraffin-control rate gradually increased with the magnetic properties of the SF powders increased.The additions of the SF powders were 2 %,the paraffin-control rate of magnetic coating could reach to 77.3 %.On this base,we added 0.6 % PEG to the coating,the paraffin-control rate reached to 80.1%.We considered the wax was effected by the magnetic field,and then the wax motion shifted to the directional movement.
