Abstract
The invention provides an electrical steel environment-friendly high-insulation coating. The electrical steel environment-friendly high-insulation coating is characterized by being prepared from, by mass, 5%-20% of barium zirconate, 1%-10% of aluminum phosphate, 5%-20% of CaFeO3, 5%-30% of titanium dioxide, 1%-10% of barium sulfate, 10%-30% of waterborne acrylic emulsion, 1%-5% of wetting agent, pH modifier and defoaming agent, and the balance deionized water. The granularity of all the powder is larger than or equal to 1,000 meshes. The electrical steel environment-friendly high-insulation coating has the advantages of being environmentally friendly, low in price, excellent in comprehensive performance and large in economic and social benefits and being used for electrical steel surface coating.
Description
Technical field
The invention belongs to and the present invention relates to field of metal surface treatment technology, particularly a kind of electrical steel environment protecting high-insulating coating.
Background technology
Electric steel insulating paint field, will there be one deck insulating coating on electrical sheet surface, and to provide a surface resistivity, the power loss of the lamination that electrical sheet is formed interlayer is in use down to minimum.This insulating coating not only will have good insulativity, tack and solidity to corrosion, also needs good punching processibility, weldability and annealing thermotolerance etc.
Existing electric steel insulating coating has inorganic coating, organic coating and half inorganic coating three major types.Organic coating film forming and punching good, but heat-shrinkable is large, hardness is low, poor heat resistance and toxicity etc.; Inorganic coating good heat resistance, but punching and tack poor; Half inorganic coating has good over-all properties, is the current type generally adopted.As L, L2, L3 coating of Nippon Steel, AN, J coating of JFE, T4, T5 coating of Wuhan Iron and Steel Plant, A, H coating of Baosteel, the G2 of Taiyuan Iron and Steel Co., C6A, C6B coating of Korea S's Pu item and the TW1 coating etc. of Russian Xin Lipeicike are half inorganic coating, and mostly containing chromic salt.Part is not containing the environment-friendly coating of chromium, and as the H coating etc. except Taiyuan Iron and Steel Co. X4, H5 and Wuhan Iron and Steel Plant, its tack, punching, thermotolerance, solidity to corrosion and economy etc. are far below containing chromate coating.
Summary of the invention
The object of the present invention is to provide one not containing chromium, and the high insulation compound that tack, punching, thermotolerance, solidity to corrosion and economy are good, technical scheme of the present invention is:
A kind of electrical steel environment protecting high-insulating coating, described electrical steel environment protecting high-insulating coating is formulated by the component of following mass percent:
More than above-mentioned all powder particles >=1000 order.
The invention also discloses the preparation method of described electrical steel environment protecting high-insulating coating, comprise the following steps: after mixing under homogenizer, enter under sand mill is ground to fineness≤5 μm, filter and package.
This technology adopts zirconate, phosphoric acid salt, uhligite (CaFeO
3), water-base resin, auxiliary agent and deionized water etc. are main raw material, not containing heavy metals such as chromium, lead, cadmium, mercury, not containing organic solvent.Zirconate, phosphoric acid salt etc. form fine and close and complete film in metallic surface, impel metal passivation, prevent corrosion of metal; Uhligite (CaFeO
3) there is larger resistivity; Water-base resin ensure that the tack and processing characteristics etc. of coating.
Advantage of the present invention is: environmental protection is inexpensive, and for electrical steel surface-coated, properties of coating is excellent, has larger economic and social benefit.
