SHEET OF MAGNETIC STEEL WITH SEMI-ORGANIC INSULATION COATING

摘要

FIELD: metallurgy.SUBSTANCE: invention relates to metallurgy, particularly, to sheet of magnetic steel with semi-organic insulation coating. Said coating comprises inorganic component and organic resin. Inorganic component contains Zr compound in amount of 20-70 wt % (per ZrO), Si compound containing plate-like silicon dioxide in amount of 10-50 wt % (per SiO) per dry coating and compound B in amount of 0.1-5 wt % (per BO) per dry coating.EFFECT: high corrosion and water resistance, high resistance to chalking, scoring and sticking.5 cl, 1 dwg, 10 tbl, 2 ex
