Description

240310

The present invention relates to a solution for forming electrotechnical coatings having amorphous metal magnetic materials.

The magnetic properties of amorphous metal ferromagnets are largely determined by the chemical composition and the physical structure of the metal magnetics and the physico-chemical properties of the surface of the metal magnet. Both of these factors overlap in their effects and determine the resultant magnetic properties, that is to say, the pre-magnetizing losses of the ferromagnetic metal, the physicochemical properties of the surface ferromagnetic being significantly affected by the composition of the electrical coating. When studying the chemical composition of amorphous metal strips prepared by extremely rapid cooling, the Auger electron spectroscopy method was found to be amorphous on the surface and inwardly. metal tapef. the segregated zones of the individual elements are found. The etching of the amorphous metal band surface by the various aggressive solvents of the carbonate effect has the effect of etching and the size of the premagnetic losses. Also, while observing the gradual etching of the surface of the amorphous metal strips by the aggressive solvent-potentiometric method, it has been found that not only segregated zones are present at the surface of the fluffy stripes, but also the oxidic layers reacting with the coating solutions in the electrotechnical coating process and At the coating interface, compounds form suitable physicochemical properties that affect the measured magnetic properties of the metal ferromagnets. V čs. AO No. 221 182 phosphate and phosphate nanoborate coating solutions for amorphous metal materials contained only small ionic radii.

The composition of the described dihydrophosphate and dihydrophosphonate coating solutions did not provide the possibility of using ions with larger ionipolymers and did not respond to the influence of the presence of other substances in the coating solutions, or other substances which are present in the coating solutions. in order to prevent the formation of coarse precipitates, for example, non-magnetizing losses in amorphous metal-magnetics.

These drawbacks are eliminated by the solution for producing electrotechnical devices on amorphous metal magnetic materials, which is based on the fact that it consists of 0.05 to 5 wt. parts of a surfactant based on alkylbenzene sulfenates and / or based on alkylene and / or nitrogen-based ethylene oxide condensates with triethanolamine and / or salts of organic phosphate esters and from 5 to 80 wt. parts of a water-miscible organic solvent such as methyl alcohol and / or ethyl alcohol and / or n-propanol and / or isopropyl alcohol and / or acetone and / or dioxane and from 1 to 4 wt. parts of aqueous phosphoric acid and sodium dihydrogen phosphate and / or potassium phosphate in an amount of 1 to 600 wt. of zinc dihydrate or zinc dihydrate in an amount of 1 to 200 wt. and / or magnesium dihydrogen phosphate and / or aluminum in an amount of 1 to 100 wt. all the phosphates are in the form of an aqueous solution. The solution may still contain other ingredients, 0.01 to 5 wt. parts of sodium borate and / or lithium and / or 0.01 to 1 wt. part of boric acid, and / or 0.005 to 10 wt. parts of nitromethane and / or nitroethane, and / or 0.005 to 2 wt. parts (oraldehyde and / or acetaldehyde, and / or 0.005 to 7.5 parts by weight of sulfuric acid and / or salts thereof and / or 0.01 to 3 parts by weight of sulfuric acid and / or salts thereof and / or hydrochloric acid] and / or its salts in an amount of from 0.01 to 5 parts by weight and / or from the nitric acid or its salts in an amount of 0.1 to 1.5 parts by weight, the salts of said chromic, ferrous, ferric, cadmium, nickel, manganese, titanium, sodium, potassium, ammonium, and / or 0.01 to 5 wt.% formic and / or acetic and / or ammonium, potassium, aluminum, magnesium, lithium and sodium; and / or 0.01 to 0.5 parts by weight of complexes I and / or III and / or IV, and / or 0.01 to 5 parts by weight of ethethanolamine and / or diethanolamine and / or triethanolamine, and / or or 0.01 to 4 parts by weight of ammonium, chromium and / or barium ammonium, ammonium, potassium and sodium carbonate / or bicarbonate in an amount of 0.001 to 3 parts by weight; parts of ammonium, potassium, lithium, sodium, magnesium hydroxides.

A solution for generating electrotechnical coatings on amorphous metal materials means that coatings simultaneously increase magnetic saturation induction, increase initial maximum permeability, and reduce pre-magnetization losses in their alternating pre-magnetization by electromagnetic fields.

A further advantage of the solution for forming electrotechnical coatings on amorphous magnetic materials is that the electro-technical coatings formed from the solutions of the invention, especially in their two-phase firing, have good adhesion to the material and can produce high quality films. Considering their mechanical properties, their thickness being uniform, they increase the chemical resistance of the surface of the amorphous metal strips to the external influences and at the same time they can stimulate the electrical properties (electrical resistance) of the formed coatings.

The material was biphasic at 240 ° C and at 360 ° C, the evaporation was always the same, 5 minutes, Example 5 8 The procedure was as in Example 3, 4, 5,7, 9 or 11 sec. except that as much hydroxamide ammonium was added to the coating solution to be 0.3 (half weight, in weight of hydroxyl ions, and total weight), the material was biphasic at 240 ° C and 360 ° C; Example 5 9 The procedure was as in Examples 1, 2, ... 11 or 12 except that so much sodium hydroxide was added to the loading solution. to a concentration of 0.01 parts by weight, drawn to the weight of hydroxyl ions and to the mass of the whole solution, the material was biphasic at 240 ° C and at 360 ° C, the evaporation was always the same for 5 minutes. HPV was tested on amorphous metal strips prepared by extremely rapid cooling of various chemical compositions. The chemical composition of the amorphous Fe4NiO4BBoO metal bands resulted in a reduction of more than 50% of the premagnetization losses, with a reduction of more than 55% of the premagittation losses in the chemical composition of the amorphous metal strips (Co85Fe5Cr9) 78SieBi4 and CoseFee-NiioSinBi5. and for amorphous strips of the chemical composition FesOnija-CrioMo2Si15Bi5, the reduction of the premagination losses was more than 60% in comparison to the training stavoro. This different reduction in premagnetisation losses, which was measured at the time of the finding that it is premagnetized by electromagnetic field 50, 145 and 190 Hz, as well as the difference in color of the resulting electrotechnical coatings using the same coating solutions in the firing process for the individual materials. confirms that in the process of creating! In the case of electrotechnical devices at the interface of coatings, chemical compounds of suitable physico-chemical properties, which influence the magnetic properties of the metal materials, arise. The electrical resistance of the insulating layers, which is also dependent on the composition of the coating solutions and the processing technology of these coating strips for electrical trains, measured between the yard metal electrodes attached to the tape surface of 1.5 cm in width, may be greater than the IQ -ďQ. přďmeτ A solution for forming electrotechnical coatings on smorphous metal magnetic materials, characterized in that it comprises 0.05 to 9 wt. tertiary benzene sulphonate and / or alkyl phenol / alpbo based surfactants based on nitrogen ethylene oxide condensates with triethanol aninine (or based on propylene oxide and olefin addition products and / or organic phosphate ester salts); 5 to 80 parts by weight of a water-miscible organic solvent such as methanol and / or ethyl alcohol or n-propanol and / or isopropanol and / or acetone and / or dioxane; of d-phosphoric acid in the free solution and sodium and / or potassium hydrogen phosphate in an amount of 1 to 603 wt. and / or zinc dihydrogen phosphate in an amount of 1 to 200 wt.% and / or magnesium dihydrate and / or aluminum in an amount of 1 to 109 wt. all the phosphates are in the form of an aqueous solution. 2.
