Description
Technical field
The present invention relates to steel plate coating, belong to definitely the oriented silicon steel Chrome-free insulation coating, be in particular a kind of environment-friendly type insulated dope that can improve the oriented silicon steel surface brightness.
Background technology
EU Committee in 2003 and European Parliament have promulgated two stereotyped commands, that is: the instruction (ROHS) of some objectionable impurities is used in restriction in the instruction of electronic and electrical equipment waste and the electronic and electrical equipment.Command request, the index of harmful element must be up to specification in the electric equipment products that on July 1st, 2006 rose to sell on the EU market, and the objectionable impurities that namely will limit has; Cadmium, lead, mercury, sexavalent chrome, Polybrominated biphenyl, polymerization bromination biphenyl ether etc.Namely taken the lead in requiring to enter in its regional electrical sheet containing the chromium element, will have from now on increasing countries and regions to propose the requirement that class is.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.
After containing chromium coating and be coated on directional silicon steel originally, although its surperficial luminance brightness is more than 30, because not environmental protection namely contains harmful element chromium, so must eliminate.
In recent years, the domestic and international technician of this area has carried out a large amount of experimental study work in line with environmental protection spirit, from the situation of retrieval, although cloth has contained chromium, but surface brightness is poor, the highlyest is no more than 15, and is of light color and inhomogeneous, use impact on the user is very large, lamination is difficult to arrangement, affects the preparation efficiency of iron core, and user satisfaction is poor.Such as following existing technology, the problem under all existing:
Korean Patent Application No. is the patent documentation of KR20010082119, discloses a kind of Chrome-free oriented electrical steel and insulating coating thereof, and its insulating coating comprises: zinc phosphate; Trimagnesium phosphate; 0.5-12% boric acid or contain a kind of in the borate of Na, Al, Ca, Li, Mg.The existing deficiency of the document is: the coating erosion resistance is relatively poor, and the appearance of coat luminance brightness is no more than 10, lighter color, and inhomogeneous, friction is difficult for arrangement greatly when the iron core of preparation transformer, and preparation is surperficial with the duration oriented silicon steel.
Japanese patent application No. is the patent documentation of JP19790150688, has introduced a kind of insulating coating for the Chrome-free oriented silicon steel, and its content comprises: 7-60 part trimagnesium phosphate; 8-40 part one or two kind of vitriol; 20 parts of silica gel.The result of coating shows that the coating tack is general, and the appearance of coat luminance brightness is no more than 10 equally, and the corrosion resistance nature of coating is relatively poor.
China Patent No. is the patent documentation of ZL200610030717.6, and it discloses a kind of oriented silicon steel chromium-free environment-friendly insulating coating.Its chemical ingredients mass percent is: 0.01% ~ 3% block polyether nonionic surface active agent, 0.2% ~ 3% boric acid, 9% ~ 30% aluminium dihydrogen phosphate, 8% ~ 20% colloid silica.Its deficiency is: the coating non-refractory, cause corrosion-resistant, and the appearance of coat luminance brightness is no more than 10 equally.
Chinese patent application number is 201110410686.8 patent documentations, the insulation compound of the inorganic chromium-free environment-friendly that a kind of oriented silicon steel uses is disclosed, it adopts vitriol and molybdate to replace chromic anhydride, although it is all better that coating insulation, solidity to corrosion, tack and magnetic are improved situation, but still exist the coating luminous degree lower, namely be no more than 15, coating color is partially shallow and homogeneity is relatively poor, so large owing to rubbing when the iron core of preparation transformer, cause being difficult for arrangement, make preparation iron core duration, inefficient deficiency can't satisfy user's demand.Therefore the surface quality problems that solves oriented silicon steel becomes instant thing.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of insulating coating of oriented silicon steel guaranteeing environmental protection, under insulativity, solidity to corrosion, tack and the prerequisite that has excellent magnetic characteristics, make surface brightness at least 25, frictional coefficient is little, color and luster is dark and evenly, the easy environment-friendly type insulated dope that can improve the oriented silicon steel surface brightness of operation and arrangement during the iron core of preparation transformer.
Realize the measure of above-mentioned purpose:
