Abstract
The invention relates to a composite copper-plated alclad varnished wire, and relative production, wherein the invention is formed by composite wire and composite insulated layer; the composite wire is a wire whose aluminum corn is coated with copper layer; the composite insulated layer is formed by coating medlin or modified Mylar on the copper layer as bottom layer, than coating polyamide-imides paint on the bottom layer as surface insulated layer. When in production, first, coat the copper band on the outer surface of aluminum rod, to form round copper aluminum-packed rod; then drawing said rod in the drawing machine; at last, using mould method to coat bottom paint and surface paint on the packing machine. The invention can improve conductivity, reduce weight and improve the resistance in high temperature and high pressure.
Description
Technical field
The application relates to electrical material, relates in particular to enamelled wire.
Background technology
Traditional enamelled wire all is to be conductor with the copper cash, and insulating barrier is done coated with polyurethane paint in the surface.This traditional enamelled wire is because the density of copper is big, and is big with product (as the transformer) weight of its making, uses very inconvenient.Suppose to do wire rod with the less aluminium of density, because the tensile strength of aluminium is low, electrical conductivity is lower than copper, so should not select for use.In addition, traditional enamelled wire temperature index only is 130 grades or 155 grades, is not suitable for high temperature and high pressure environment.
Summary of the invention
The application's purpose is the deficiency that overcomes existing enamelled wire, proposes a kind of compound paint copper-in-aluminum enameled wire and production method thereof.
The cross-section structure of the described compound paint copper-in-aluminum enameled wire of the application comprises: compound wire and composite insulation layer.Wherein:
(1) described compound wire is to be coated with the outer field lead of copper at the aluminium core;
(2) described composite insulation layer be the copper superficies scribble polyester-imide or modified polyester resin be the lacquer of base-material as prime coat, on the priming paint again polyamide coating acid imide lacquer as surface insulation layer.
The characteristics of this novel enamelled wire are: 1, according to conductor theory, electric charge flows at conductive surface and forms electric current, the conductor of copper cover aluminum just in time meets this theory, neither influence conductivity, reach the purpose of light weight again, 2, to adopt heat-resistance index be that 200 grades polyester-imide lacquer or modified poly ester is priming paint to the application, heat-resistance index is that 220 grades polyamidoimide lacquer is the table lacquer, two kinds of insulating varnish are as composite insulation layer, make the temperature coefficient of enamelled wire can reach more than 200 grades even can reach 220 grades, be applicable to high temperature and high pressure environment.
The production of this novel enamelled wire can be adopted following method:
1, high-quality copper strips is coated on the aluminium rod outer surface with one heart, forms circle copper cover aluminum bar, circle copper cover aluminum bar is the atomic bond metallurgical junction zoarium of two kinds of different metal materials.
2, above-mentioned copper cover aluminum bar be placed on carry out wire drawing on the wire drawing machine, require during wire drawing:
(1) tower of wire drawing machine joint is 1: 1.1 than (diameter of two-stage cone pulley ratio up and down), and the compression ratio of wire-drawing die is 12%, and line speed is 1000 meters/minute.
(2) lubricating fluid is made by 60 parts of mineral oil, 5 parts of polyethylene glycol, 5 parts of aliphatic acid, 5 parts of emulsifying agents, 5 parts of ethanol, 20 parts of additives and 8 parts of water;
Above-mentioned umber is parts by weight, and additive comprises anti-bubble, antibiotic and anticorrosive additive.
3, adopt die methods primer coating layer on enamelling machine, it is 200 grades polyester-imide lacquer or modified polyester resin lacquer that prime coat selects heat-resistance index, and the polyamidoimide lacquer that applies heat-resistance index on the priming paint again and be 220 grades is as surface insulation layer, the coating processes parameter:
Threading speed is: 28 meters/minute, and 360 ℃ of process annealings during threading, 400 ℃ of low temperature are coated with roasting, 450 ℃ of annealing when japanning is produced, 500 ℃ of high temperature cure, and the coating pass of priming paint is 11 times, and the coating pass of surface lacquer is 4 times.
Insulating varnish with two kinds of different qualities, through equality of temperature speed together, different japanning passes, compound being coated on the copper clad aluminum conductor, the production technology of this " low temperature threading-high temperature production ", the cracking that the coefficient of expansion caused that copper cover aluminum is different in the time of can effectively solving high temperature low speed reveals aluminium or copper combines bad phenomenon with aluminium.
Description of drawings
Fig. 1 is the application's an enamelled wire sectional drawing.
Marginal data: 1-aluminium core, 2-copper skin, 3-prime coat, 4-surface insulation layer.
Embodiment
As shown in Figure 1, the application's section structure comprises: compound wire and composite insulation layer.Wherein:
(1) described compound wire is the lead that is coated with copper skin 2 at aluminium core 1;
(2) described composite insulation layer be scribble on outer 2 surfaces of copper heat-resistance index be 200 grades polyester-imide or modified polyester resin be base-material lacquer as prime coat 3, on the priming paint 3 again heat-resistance index be that 220 grades polyamide coating acid imide lacquer is as surface insulation layer 4.
Production method is as described in the summary of the invention, and does following replenishing:
1, the copper cover aluminum bar processing of will detecting a flaw.
2, selecting coating apparatus for use is the DL280 enamelling machine that German AUMAN company produces, or Italian SICME company SV1000 and the SHM2-750 enamelling machine produced.The said equipment VD value is high, excellent catalytic effect, environmental protection and energy saving.
3, the paint material of selecting for use that is coated with is polyester-imide lacquer and the polyamidoimide lacquer that German A Ertana company produces.
4. comprise anti-foaming agent, antiseptic and corrosion inhibitor in the additive.
