摘　　要：介绍了马钢无取向电工钢用M11含铬绝缘涂层的开发过程及工艺流程。并对其性能进行了检测分析,结果表明,M11含铬绝缘涂料是一种主要由丙烯酸树脂乳液、重铬酸锌水溶液、硼酸、甘油等组成的半有机涂料,其性能满足电工钢连续退火生产线高速辊涂的需要;通过涂层工艺的合理控制,M11含铬绝缘涂层,其层间电阻在150Ω.mm2/片以上,综合性能满足电工钢用户的需要。The development, performance and application of Mll chromate-containing insulation coating on non-oriented electrical steels of Masteel was presented. The M11 paint developed by Masteel is a semi-organic material, mainly composed of acrylic resin emulsion, zinc dichromate solution, boric acid and glycerol. It can be applied in the high speed roll coating of electrical steels made by continuous annealing lines. The interlamination resistance of Mll chromate-containing insulating coating is above 150Ω.mm^2 per piece; and its comprehensive properties can satisfy the requirements of users.
