Abstract
The utility model relates to the technical field of enamelled wires, in particular to an enamelled wire with a polyester coating priming coat film, which comprises a metal conductor core wire and an insulating coating coated on the periphery of the core wire, wherein the insulating coating comprises a polyester coating priming coat, a polyester imide coating rough coat and a polyamide imide coating skin coat from inside to outside sequentially. The coating film formed by the polyester coating has good flexibility and conductor adhering capacity, in addition, the viscosity of the polyester coating is easily adjusted into an appropriate viscosity in the process of preparation and is obviously smaller than that of the same amount of polyester imide coating, thereby the polyester coating has good levelling property so as to be favorable for pulling the coating film to be a round shape, accordingly, the enamelled wire with the polyester coating priming coat film has small non-roundness, good adhesiveness of the coating film, and high flexibility of the coating film.
Description
Technical field:
The utility model relates to the enamelled wire technical field, particularly has the enamelled wire of polyester lacquer prime coat paint film.
Background technology:
Enamelled wire applies the insulation enamelled coating outward by metal core wire and constitutes.Existing enamelled wire, the coated insulation enamelled coating of its heart yearn outer rim generally adopts the paint film structure of polyester-imide lacquer (PEI) composite polyamide acid imide lacquer (PAI), mainly there is following defective in the enamelled wire of this structure: 1, the deviation in roundness of paint film is big, core shift degree height; 2, the paint film tack is relatively poor, and the lacquer that very easily contracts when breaking experiment is done in performance; 3, paint film flexibility is relatively poor.Paint film cracking easily takes place when finishing the stretching and winding experiment, and the corner is easy to crack when using the enamelled wire coiling motor coil of wire.
The utility model content:
The purpose of this utility model is to provide a kind of enamelled wire with polyester lacquer prime coat paint film at the deficiencies in the prior art, and this enamelled wire deviation in roundness is little, and the paint film tack is good, the pliability height.
For achieving the above object, the utility model adopts following technical scheme:
Have the enamelled wire of polyester lacquer prime coat paint film, it comprises the metallic conductor heart yearn and is coated in the insulation enamelled coating of described heart yearn outer rim; Described insulation enamelled coating comprises polyester lacquer prime coat, polyester-imide lacquer bottom and polyamidoimide lacquer painting layer from the inside to the outside successively.
Further technical scheme of the present utility model comprises:
The thickness of described polyester lacquer prime coat accounts for 8%～12% of described insulation enamelled coating gross thickness.
The thickness of described polyester-imide lacquer bottom accounts for 63%～72% of described insulation enamelled coating gross thickness.
The thickness of described polyamidoimide lacquer painting layer accounts for 20%～25% of described insulation enamelled coating gross thickness.
Described heart yearn is an aluminium matter heart yearn.
Or described heart yearn is copper heart yearn.
Also can be that described heart yearn is many metal composite conductor core wire.
The utility model beneficial effect is: the utility model comprises the metallic conductor heart yearn and is coated in the insulation enamelled coating of described heart yearn outer rim; Described insulation enamelled coating comprises polyester lacquer prime coat, polyester-imide lacquer bottom and polyamidoimide lacquer painting layer from the inside to the outside successively; Described polyester lacquer is to carry out polycondensation reaction and the class wire enamel made by dimethyl terephthalate (DMT) and polyalcohol, formed paint film has good pliability and the ability of adhering to conductor, in addition because the polyester lacquer more easily is adjusted to appropriate viscosity in the preparation process medium viscosity, viscosity than the polyester-imide of same amount lacquer is obviously low, so its levelability will be got well, when producing, more help the circle that draws of paint film; Therefore, have the enamelled wire of described polyester lacquer prime coat paint film, its deviation in roundness is little, and the paint film tack is good, the paint film flexibility height.
Description of drawings:
Accompanying drawing 1 is a schematic cross-section of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described, sees shown in the accompanying drawing 1, this is a better embodiment of the present utility model.
Enamelled wire with polyester lacquer prime coat paint film, it comprises metallic conductor heart yearn 1 and is coated in the insulation enamelled coating 2 of described heart yearn 1 outer rim; Described insulation enamelled coating 2 comprises polyester lacquer prime coat 21, polyester-imide lacquer bottom 22 and polyamidoimide lacquer painting layer 23 from the inside to the outside successively.
Production stage of the present utility model mainly comprises: 1, metal base is drawn into needed conductor core wire 1 on the wire drawing board; 2, described heart yearn 1 is carried out annealing softening, cooling; 3, apply the polyester lacquer in cooled heart yearn 1 outer rim, and dry, cool off; 4, in the 22 also oven dry of described polyester lacquer prime coat 21 surface-coated polyester-imides lacquer bottom, cooling; 5, in described polyester-imide lacquer bottom 22 also oven dry of surface-coated polyamidoimide lacquer painting layers 23, cooling.
Polyester described in the utility model lacquer is to carry out polycondensation reaction and the class wire enamel made by dimethyl terephthalate (DMT) and polyalcohol.Its main component is branched linear polyester resin, all has activity hydroxy on its end of the chain and side chain, in being coated with line process, bakes and banks up with earth through high temperature, and diluent and solvent are progressively evaporated, and further polymerization of mylar and cracking form the thermosetting polyester paint film; Because the unique linear structure of polyester paint film, therefore the polyester paint film has good pliability and the ability of adhering to conductor, in addition because polyester paint more easily is adjusted to appropriate viscosity in the preparation process medium viscosity, viscosity than the polyester-imide of same amount paint is obviously low, so its levelability will be got well, when producing, more help the circle that draws of paint film.
Wherein, the thickness of described polyester lacquer prime coat 21 accounts for 8%～12% of described insulation enamelled coating 2 gross thickness.
The thickness of described polyester-imide lacquer bottom 22 accounts for 63%～72% of described insulation enamelled coating 2 gross thickness.
The thickness of described polyamidoimide lacquer painting layer 23 accounts for 20%～25% of described insulation enamelled coating 2 gross thickness.
The utility model compared with prior art, its effect comparison sees Table 1, wherein, adhesive force be with jerk have no progeny contract the lacquer length consider, paint film flexibility is to consider with the stretching and winding paint film cracking.
Table 1:
| Deviation in roundness | Adhesive force | Pliability | |
| Prior art | 0.005mm | 3.0-7.0mm | The 2D cracking of reeling |
| The utility model | 0.002mm | 0.5-2.0mm | Stretching 20%, 2D reel and do not ftracture |
Wherein, described heart yearn 1 can be aluminium matter heart yearn, copper heart yearn; Also can be that described heart yearn 1 is many metal composite conductor core wire, as the copper cover aluminum composite conductor.
The above only is a better embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
