Description
Technical field
The present invention relates to a kind of non-crystaline amorphous metal special non-solvent epoxy mass-impregnation paint and preparation method thereof.
Background technology
Non-crystaline amorphous metal is by 80%Fe and 20%Si, category-B metallic element formed, it has high saturated magnetic induction (1.54T), the everyways such as magnetic permeability, magnetizing current and iron loss are better than the feature of siliconized plate, particularly iron loss low (1/3-1/5 for grain-oriented Si steel sheet), replaces silicon steel to do substation transformer and can save energy 60-70%.The thickness of strip of non-crystaline amorphous metal is about 0.03mm, is widely used in substation transformer, high power switching power supply, pulse transformer, magnetic amplifier, intermediate frequency transformer and invertor iron core, is applicable to below 10kHz frequency usage.Due to super quench solidification, during alloy graining, atom has little time ordered arrangement crystallization, and the solid alloy obtained is longrange disorder structure, does not have the crystal grain of crystal alloy, crystal boundary, is referred to as non-crystaline amorphous metal, is called as a revolution of metallurgical material.This non-crystaline amorphous metal has the performance of many uniquenesses, as the magnetic of excellence, solidity to corrosion, wear resistance, high intensity, hardness and toughness, and high resistivity and electromechanical coupling performance etc.Because its excellent performance, technique are simple, from the eighties, just become the research and development emphasis of domestic and international material supply section educational circles.
Mass-impregnation paint is the indispensable important materials of motor and transformer industry, current solvent impregnating varnish is also in a large amount of use, these are rich in the impregnating varnish of organic solvent, in transport and use procedure, capital gives out harmful gas, and then causes human body dizzy, irritated, poisoningly wait detrimentally affect, mishandlingly very easily cause security incident.Therefore, how to reduce VOC volatilization, developing low-cost, high performance solvent-free immersion paint becomes focus and the emphasis in this field.
Current Amorphous Metal Motor or transformer producer use the impregnating varnish of epoxy Dyhard RU 100 series, and its shortcoming is that viscosity is large, cause the mobility of paint and wetting property poor, the number of dropouts of paint is large; Stability in storage is poor, must separate packing and storing, component A and B component mixture 40 degree of storages 6 days, and viscosity can increase 4-5 doubly, even produces gel.
Also have some producers to use the impregnating varnishes such as AS6701, AS6702, such impregnating varnish belongs to few solvent polyester modification vinylformic acid impregnating varnish, has good mechanical property, electric property and resistance toheat.But there is following shortcoming: (1), in actual production process, production technique is comparatively complicated, in production process, energy consumption is large, and preparation cost is higher; (2) in actual use, the hot dielectric loss of paint is bigger than normal, and cohesive force is on the low side, easily produces the phenomenons such as discrete piece, be difficult to advantage of competing in cost in cutting process.
