Description
Technical field
The present invention relates to a kind of coating, relate in particular to a kind of oriented silicon steel coating of environmental protection.
Background technology
Nineteen fifty, U.S. Armco company has proposed the C-5 coating the earliest, and this is a kind of inorganic phosphate magnesium coating.1973, Kawasaki, Japan system iron proposed to add on this basis the D coating of aluminum nitrate and chromic acid again.Then, Japanese Nippon Steel has proposed stress coating T-2 coating, and its composition is colloid silica, aluminium dihydrogen phosphate and chromic trioxide.Armco has also proposed the stress coating, and main ingredient is aluminum phosphate, trimagnesium phosphate, gluey SiO
2And chromic acid, be called the Carlite-3 coating.
Japanese Patent No.: clear 52-25296, clear 53-143737 disclose the stress coating of Kawasaki Steel, and component is colloid SiO
2, primary magnesium phosphate and chromic acid form, and add SiO
2, Al
2O
3Or TiO
2Fine powder takes place bondingly when preventing stress relieving, and propose to improve water tolerance with boric acid and vitriol replacement chromic acid.
All have chromic acid in the above-mentioned oriented silicon steel insulating coating, be used to improve rust-preventing characteristic, the water tolerance of vitriol coating and make phosphoric acid salt more stable, yet chromic acid is the material to environment and human body harmful.
On February 13rd, 2003, EU Committee and European Parliament issued two stereotyped commands, that is: the instruction (ROHS) of some objectionable impurities of restriction use in instruction of electronic and electrical equipment waste (WEEE) and the electronic and electrical equipment.Command request, the index that played harmful element in the electric equipment products of selling on the European Union market on July 1st, 2006 must be up to specification, and promptly the objectionable impurities that will limit has: cadmium, lead, mercury, sexavalent chrome, Polybrominated biphenyl, polymerization bromination biphenyl ether etc.Promptly taken the lead in requiring to enter in its regional electrical sheet containing the chromium element, will have more and more countries and area to propose similar requirement from now on.
In order to overcome the shortcoming that contains the harmful coating of chromium, silicon steel manufacturer considers to come the substitute chromium acid anhydrides with the material of other form both at home and abroad.External other material of interpolation that mostly is that adopts comes the substitute chromium acid anhydrides, but because the limitation of the new character of additive own has caused coating performance to have certain defective.
Japanese Patent No.: the spy opens flat 2000178760, Te Kaiping 2000169973, Te Kaiping 2000169972, it discloses Nippon Steel and has proposed to come the substitute chromium acid anhydrides with the organic acid metal-salt, for example: calcium formiate, zinc formate, formic acid manganese, tin acetate, oxalic acid and manganous tartrate etc., the result who applies shows that the coating tack is better, but solidity to corrosion and to improve the magnetic property ability general.
Japanese Patent No. spy opens that the Kawasaki Steel proposes to come the substitute chromium acid anhydrides respectively with lithium tetraborate, lime borate, aluminum borate, Tai-Ace S 150, ferric sulfate, manganous sulfate and aluminum oxide and zirconia solid particle in flat 2005068493, the result who applies shows that the coating tack is general, but solidity to corrosion, outward appearance and to improve the magnetic property ability better.The coating that this class does not contain chromium has satisfied environmental protection requirement really, but its weak point is: owing to lacked chromic trioxide in masking liquid, both caused liquid to become relatively poor for the wettability of substrate, and caused appearance of coat not good; Make the corrosion resisting property of coating become unsatisfactory again,, can't on comprehensive evaluation, obtain satisfied result so can only satisfy a certain or several performances of coating preferably.
Japanese Patent No.: the spy opens and puts down 10015484, and the spy opens flat 10015485 and discloses the chromium-free environment-friendly coating that is applied to non-oriented electrical steel.Propose in these patents to substitute dichromate, thereby when satisfying performance, reach environmental requirement with a large amount of different organism.But oriented silicon steel insulating coating also has the process of a step high temperature sintering after the low-temperature bake drying, so all inefficacies of carbonization at high temperature of the organism in such non-oriented electrical steel coating, and then has lost the characteristic of original coating.Moreover the inorganics component concentration is few and can not be after oven dry the substrate of oriented silicon steel be formed tension force in the environmental protection masking liquid of non-oriented electrical steel, so reach the basic demand that relies on coating to reduce iron loss, improve magnetic strength.
