摘　　要：针对目前大部分无取向电工钢处理液为含铬处理液、且需在较高温度下固化的情况，在分析成膜物质性质的基础上，试验研究了一种可低温快速固化的电工钢环保绝缘处理液，研究了其涂装工艺，并测定了涂层的附着性、绝缘性、耐热性、耐蚀性等性能。试验结果表明：该处理液可在150～250℃下快速烘干固化，涂层表面光滑且致密均匀，性能优良，可满足中小电机的使用要求。At present, most of the insulating fluid for nonoriented electrical steel contains chromium, and should be cured at high temperature. On the basis of analyzing the characteristics of the filmforming substance, a kind of ecofriendly insulating fluid with lower curing temperature for nonoriented electrical steel sheet was developed in the experiments. Then its coating process was studied, and the adhesive ness, insulativity, heat resistance, corrosion resistance and other properties of the coating was measured. The results show that the fluid can be rapidly dried and cured at 150℃ to 250 ℃, and the resulted smooth, compact and uniform coating with excellent performance can meet the application requirement of small and mediumsized motors.
