ELECTRICAL SHEET STEEL WITH INSULATION COATING |
摘要 |
FIELD: metallurgy.SUBSTANCE: insulation coating is obtained as a result of application of a surface treatment agent at least to one side of electrical sheet steel and drying of the surface treatment agent. The surface treatment agent contains trialkoxysilane and/or dialkoxysilane (A), in which a substituent fixed with Si is formed only with at least one nonreactive capable substituent chosen from a group consisting of hydrogen, an alkyl group and a phenyl group; and a silane binding agent (B) at weight ratio of (A/B) in the range of 0.05 to 1.0.EFFECT: providing excellent formability, an adhesive ability of the coating, properties of the coating film after annealing, weldability at gas-tungsten welding, corrosion resistance and resistance to pressure slides even without any content of any chrome compound in an insulation coating.4 cl, 4 tbl |
