Abstract
The utility model provides a multi-coating high performance varnished wire, comprising a metal conductor and characterized in that the metal conductor is successively covered by a modified polyamide-imide primer layer, a polyesterimide layer, a polyamide-imide layer and a nylon finish paint layer which commonly form a total paint film. The multi-coating high performance varnished wire possesses good adhesion performance, mechanical property, high temperature resistance, heat shock resistance, hydrolytic resistance, etc. The polyamide-imide layer is used as a second paint film and has high heat resistance, high cut-through temperature, excellent electricity performance, flexibility and adhesiveness. The nylon finish paint layer can reduce surface friction coefficient, the surface possessing good smoothness.
Description
Technical field
The utility model belongs to Production of Enamel Wires field, and the material that is specifically related to a kind of overbrushing floor height performance enamelled wire forms component.
Background technology
Enamelled wire is a kind of winding wire, by conductor and insulating barrier, formed, the enamelled wire that conventional production methods is produced is generally on the conductor for preparing copper cash or aluminum steel, to apply one deck or two-layer insulating varnish pasta paint, cause enamelled wire machinery performance and the surperficial slip of traditional mode of production general, flexibility is lower, the as easy as rolling off a log cracking phenomena that causes paint film of common stretching, for the production of in make product disqualification rate high, especially reprocessabilty with stretch in paint film easily cause damage, and may cause the rotor of manufacture to occur the bad or short circuit of turn-to-turn.Along with the continuous variation of applied environment and the progress of science and technology, the quality requirement of enamelled wire is progressively improved.Three coating enamelled wires are on the basis of two coatings (polyester-imide+polyamide-imide insulating varnish), and surface increases by 1 layer of self-lubricating polyamide acid imide insulating varnish, can improve surperficial slip and the resistance to wear of enamelled wire.But, when producing large specification enamelled wire or being coiled into amount of tension products bigger than normal such as being similar to reactor, because paint film adhesion is not enough, be easy to occur the great quality hidden danger of paint film cracking.How improving elongation and the lubrification of insulating varnish adhesive force and the paint film of enamelled wire, is the problem that in producing at present, urgent need is researched and solved.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of composition structure that improves the tensile strength of overbrushing floor height performance enameled wire coat, resistance to pessimum, extensibility and surperficial slip.Strengthen the adhesive force of enameled wire coat, and meet after enamelled wire Uniform Tension 20%, then carry out the test of 1D coiling, enameled wire coat there will not be the requirement of cracking.
The technical scheme that the utility model overcomes the above problems is, a kind of overbrushing floor height performance enamelled wire, comprise metallic conductor, it is characterized in that: metallic conductor is coated with modified polyamide imide prime coat, polyester-imide layer, polyamidoimide layer and nylon face enamelled coating outward successively the total paint film of the common formation of modified polyamide imide prime coat, polyester-imide layer, polyamidoimide layer and nylon face enamelled coating.
The thickness of described modified polyamide imide prime coat is 0.75-1.5 μ m.
The thickness of described polyester-imide layer is 9-18 μ m.
The thickness of described polyamidoimide layer is 4.5-9 μ m.
The thickness of described nylon face enamelled coating is 0.75-1.5 μ m.
Described metallic conductor is copper material or aluminum material.
The cross section of described metallic conductor is rounded.
1. the coating structure of optimizing modification has more outstanding property.Use modified polyamide imide as priming paint, there is good adhesion property and mechanical performance.
2. use polyester-imide as second layer paint film, there is high-fire resistance, high cut through temperature, good electrical property, pliability and tack.
3. use polyamidoimide as the 3rd layer of paint film, have high temperature resistant, heat shock resistance, the chemical properties such as hydrolytic resistance and good mechanical performance.
4. use nylon as finish paint, reduce skin-friction coefficient, surface has good slip.
Accompanying drawing explanation
