Description
Technical field
The present invention relates to enameled wires, especially Inverter fed motor production of enamel wire method
Background technology
Electromagnetic wire is widely used in household electrical appliance, electronic product, motor, illumination, automobile and other industries at present.With science and technology
It is constantly progressive, various electric equipment products constantly upgrade, and need the kind of electromagnetic wire more and more, using in variable-frequency motor
In electromagnetic wire also in the product for gradually developing more excellent performance, it is original usually to use conventional polyester or polyesterimide, it is compound
The enameled wire of polyamide-imide resin production can get the paint of firm high fever and mechanical quality after japanning and solidification
Film, but polymer of these insulating layers itself itself is to the resistance very little of shelf depreciation, the spy on this On-line Discharge surface
Determine field strength or more to occur, variable-frequency motor is caused to have a serious life problem, main cause is that variable-frequency motor winding is born
High-frequency impulse pressure is very big, so that common enamel-cover line winding easily punctures, greatly shortens the service life of variable-frequency motor.
Chinese patent CN201010515475.6 provides a kind of preparation method and product of new Inverter fed motor enameled wire,
Bottom coating self-control polyester Inverter fed motor paint, is not discussed in detail its formula, and Inverter fed motor paint is because be added to nano material,
Adhesive force will substantially reduce, so bottom is not suitable for coating Inverter fed motor paint, and its speed of production is slow, and example 1.00mm only has
25m/min causes production cost to greatly improve.
JP 59 17 63 63 describes a kind of electric wire, by coated with the polyamides filled with calcined alumina and mica powder
The nickel plating Cu cores of imines enamel paint are constituted.Since the solid content of polyimides is low, complex process and enamel is uneconomical.
US patent 3,553,282, which describes, uses silicone modified polyamide acid.The polyamides of acquisition is sub-
The conducting wire of amine coating is excessively engineered for normal desired use, and very expensive.
EP 0 768 680 and EP 0 768 679 describe enameled wire, and it includes the binder components as wire enamel
By three-(2- ethoxys) isocyanurate triacrylates, 3- mercapto propyl methyl dimethoxy silanes, tetraethoxysilane
The thioether heterocycle silane prepared as filler with SiO 2.According to the record of the document, although the resistance of shelf depreciation is fine,
Heat and the mechanical performance for being it are the not at all possible requirements for reaching standard enameled wire.
EP 356929, United States Patent (USP) 4,935,302 is described contains Cr 2 O 3 and Fe 2 O 3 works with different adhesives
For the formula of filler.Two kinds of pigment all have high density, and preparation is intended to largely settle, this causes in coating process
Uneven distribution of the difficult and pigment in the enamel film of baking.
Invention content
In order to extend the service life of variable-frequency motor, meet professional standard to enameled wire heat and mechanical property requirements, this hair
It is bright that a kind of high-performance Inverter fed motor production of enamel wire method of Inverter fed motor life-span >=50 hour is provided.
In order to achieve the above objectives, high-performance Inverter fed motor production of enamel wire method of the invention is as follows：
It includes wire drawing, cleaning, annealing, natural cooling, and japanning bakes, lubrication, wire-drawing process, which is characterized in that is applying
It paints process stages to need to coat three-layer insulated coating on copper coin core wire surface, is the polyester coatings of bottom, intermediate addition respectively
The polyester imine resin layer of nano material, the polyamide-imide resin layer of the addition nano material of outer layer, three kinds of insulating layer thickness
Degree as needed coating than the bottom of to outer：4: 7: 3, coating road number is also 4: 7: 3 when production；
Above-mentioned prime paint is polyester resin, is market shaped article, and preferably this electrical insulating material (Zhuhai) of Alan's tower has
The Terester C series of limit company；
Above-mentioned inter coat is by 100 parts of polyester imine resin paints, 15 ± 2 parts of nano-titanium dioxide TiO2With 1.5 ±
0.5 part of nano silicon dioxide is uniformly mixed, then diluent is added to be transferred to viscosity needed for japanning；It is required that silica is to pass through heat
What solution was prepared；
Above-mentioned outer layer is by 100 parts of polyamide-imide resin paints, 10 ± 2 parts of nano-titanium dioxide TiO2；1 ± 0.5 part
Nanometer is uniformly mixed, then diluent is added to be transferred to viscosity needed for japanning；It is required that silica is prepared by pyrolysismethod
's.
200 grades of the Inverter fed motor enameled wire temperature resistant grade prepared by the above method；Breakdown voltage ＞ 12KV；Resistance to softening
Temperature height >=350 DEG C, 2min does not puncture；Film integrity 3000V, 30m≤1；Inverter fed motor >=50 hour.
