Brief description
Fig. 1 is structural representation of the present utility model；
Wherein, the 10th, inner wire, the 21st, Teflon turning band wrapping insulation layer, the 22nd, polytetrafluoroethylraw raw material band wrapping insulation layer, the 30th, ptfe emulsion coating, the 40th, wear-resistant coating.
Detailed description of the invention
With specific embodiment, the technical solution of the utility model is further described below in conjunction with the accompanying drawings, but protection domain of the present utility model is not limited to this.
As it is shown in figure 1, the Wear-resistant, high-temperature resistant electric wire of a kind of softness, including the inner wire setting gradually from inside to outside the 10th, Teflon turning band wrapping insulation layer the 21st, polytetrafluoroethylraw raw material band wrapping insulation layer the 22nd, ptfe emulsion coating 30 and wear-resistant coating 40.
Inner wire 10 is the multiply flexible conductor being closed by the single silver-plated of many a diameter of 0.08mm or nickel plating circular copper wire bundle, and inner wire single line number of share of stock can be the 7th, the 14th, the 21st, the 30th, the 42nd, the 62nd, the 75th, 85 or 105 etc..Owing to inner wire line diameter is little and closes structure for bundle, so conductor flexibility is good.Same electric wire, in conductor, the single line number of share of stock of same diameter is more, and electric wire current-carrying capacity is bigger, but number of share of stock is more, and wire size and weight can be bigger.Silver-plated copper conductor temperature resistant grade is 200 DEG C, nickel plated copper conductor temperature resistant grade is 260 DEG C, and nickel plated copper conductor resistance to elevated temperatures is better than silver-plated copper conductor, selects nickel plated copper conductor to be favorably improved electric wire current-carrying capacity, but nickel plated copper conductor can not weld as silver-plated copper conductor, can only crimp.Suitable conductor coating and conductor number of share of stock can be selected according to actual needs.
Wrapping insulation layer is Teflon turning band wrapping insulation layer 21 and polytetrafluoroethylraw raw material band wrapping insulation layer 22 from inside to outside.Teflon turning band wrapping insulation layer 21 uses that dieletric strength and mechanical strength are high but semi-directional Teflon turning band that film adhesion strength is relatively low, polytetrafluoroethylraw raw material band wrapping insulation layer uses dieletric strength and mechanical strength is relatively low but Low Density PTFE Unsintered Tape that film adhesion strength is higher, this structure i.e. ensure that electric wire insulation layer has enough dieletric strength and mechanical strength, makes electric wire insulation layer be not easy peeling again loose.For ensureing the dieletric strength of insulating barrier, and make insulating barrier smooth outer surface, also need to be controlled the rate of putting up of Transposed wind, turning band wrapping insulation layer put up rate preferably 50%～53%, raw material band wrapping insulation layer put up rate preferably 49%～50%.After wrapping insulation layer high temperature sintering, semi-directional Teflon turning band can occur directional retraction so that turning band wrapping insulation layer fits tightly with conductor, and high temperature also can make the adjacent turning band in insulating barrier and raw material band be bonded together.Polytetrafluoroethylene (PTFE) temperature resistant grade can reach 260 DEG C, it is ensured that the temperature resistant grade of electric wire.Low Density PTFE Unsintered Tape density is low, and nominal density is from conventional 2.2g/cm3Fall below 1.6g/cm3, greatly reduce the weight of electric wire.Semi-directional Teflon turning band and Low Density PTFE Unsintered Tape preferred white (true qualities), because color ribbon can add pigment in process, can make its dieletric strength reduce.Turning band and the film thickness of raw material band, the use voltage according to electric wire selects, preferably 0.03mm or 0.05mm etc..
It is coated with ptfe emulsion coating 30 and wear-resistant coating 40 outside electric wire, make electric wire outer surface more smooth.Ptfe emulsion coating connects wrapping insulation layer and wear-resistant coating, the preferred 0.01mm～0.05mm of thickness of ptfe emulsion coating as intermediate layer.Wear-resistant coating uses modified abrasion resistant teflon coating, and the preferred 0.01mm～0.05mm of its coating layer thickness, wear-resistant coating can be substantially improved the anti-wear performance of polytetrafluoroethylene (PTFE) wrapped electric wire.
The coating material of the utility model electric wire is made by polytetrafluoroethylene (PTFE), and temperature resistant grade is high, and environmental resistance is excellent, good flame resistance.
