Problems solved by technology

[0008] The present invention aims at the current situation that the tinting strength of the existing non-oriented silicon steel insulating coating is insufficient, by adding water-based organic color paste into the raw materials for the preparation of the current non-oriented silicon steel insulating coating, and coating the non-oriented silicon steel plate on the non-oriented silicon steel plate after being coated by a coating machine. The surface is coated, and the coating is cured by the curing and drying oven, and the color paste is used to color the coating, so as to obtain good coloring power

Embodiment 1

[0030] Take the above 100 parts of zinc chromate semi-inorganic paint, add 0.5 parts of phthalocyanine blue water-based organic color paste, stir for more than 20 minutes to ensure uniform mixing, and then apply it to the surface of non-oriented silicon steel sheet through a coating machine, and then implement according to the comparison The curing process of Example 1 is cured, and the non-oriented silicon steel with the insulating coating containing the organic colorant can be prepared.

Embodiment 2

[0034] Get 100 parts of magnesium chromate semi-inorganic coatings, add 0.5 parts of phthalocyanine water-based organic color paste, stir for more than 20 minutes to ensure uniform mixing, and then apply it to the surface of non-oriented silicon steel by a coating machine, and then according to Comparative Example 2 After the curing process is cured, the non-oriented silicon steel containing the organic colorant in the magnesium chromate insulating coating can be prepared. The scanning electron microscope morphology of the coating is as follows figure 1 shown. The colorant particles are mainly distributed on the surface of the coating, which can improve the punching performance and welding performance of the coating.

Embodiment 3

[0036] Get 100 parts of zinc chromate semi-inorganic coatings, add 0.2 parts of fruit green water-based organic color paste, stir for more than 20 minutes to ensure uniform mixing, and then apply it to the surface of non-oriented silicon steel by a coating machine, and then according to Comparative Example 1 The non-oriented silicon steel with insulating coating containing organic colorant can be prepared after curing by advanced curing process.

Abstract

The invention discloses a preparation method of non-oriented silicon steel with an insulating coating containing an organic coloring agent and the non-oriented silicon steel. A water-based organic color paste is added to the preparation raw material of the insulating coating of the existing non-oriented silicon steel, and the strong coloring of the insulating coating is realized through the enrichment of the color paste on the surface of the insulating coating after the insulating coating is dried and solidified, so that good hiding power is obtained; the color of the water-based organic color paste can be common colors, such as orchid, green, yellow, red and black, in the market, and the preferred color is blue and green; the addition amount of the water-based organic color paste is 0.1-15 percent by weight. According to the invention, the coating mode of the insulating coating is not limited; the coating added to the water-based organic color paste needs that the plate temperature is ensured to achieve 200-350 DEG C in a dried solidification furnace, and the organic color paste is enriched on the surface of the insulating coating and finally solidified in the insulating coating; because the organic coloring agent is enriched on the surface of the insulating coating, the coloring power is outstandingly enhanced, so that the coloring of the insulating coating of the non-oriented silicon steel can be realized by adding a small amount of the organic coloring agent.

Description

[0001] technical field [0002] The invention belongs to the field of non-oriented silicon steel, and particularly relates to a non-oriented silicon steel using an organic colorant in an insulating coating and a preparation method thereof. The organic colorant is added in the form of water-based organic color paste. [0003] Background technique [0004] Non-oriented silicon steel is an important magnetic material used in motor cores. In order to reduce the iron loss during motor operation and achieve energy saving and consumption reduction, it is necessary to prepare an insulating coating on the surface of the silicon steel sheet. Therefore, according to the non-oriented silicon steel products provided on the market, it can be divided into two categories, one is non-oriented silicon steel products without insulating coating, called semi-process non-oriented silicon steel, and the other is non-oriented silicon steel coated with insulating coating. Non-oriented silicon stee...
