Abstract
The utility model relates to the field of industrial cable products and preparation technology, and particularly discloses a thin PTFE (Poly Tetra Fluoro Ethylene) material belt for cables. The thin PTFE material belt adopts the structure that a shaped PTFE layer with micropores is provided; an unshaped PTFE layer is arranged on one side of the shaped PTFE layer; and the shaped PTFE layer serves as the substrate layer, so the thin PTFE material belt has high strength and toughness and is convenient to process; when the thin PTFE material belt is sintered after being wrapped on a conductor, the temperature is higher than the PTFE melting temperature; as the unshaped PTFE layer has smaller bonding fore among molecules, the molecules are in a free melting state; and owing to the micropores of the shaped PTFE layer, the molecules of the melting PTFE layer enable the whole thin PTFE material belt to be effectively wound on the conductor material or insulating material, thereby forming a good insulating layer after the thin PTFE material belt is sintered, so that the product quality is improved.
Description
Technical field
The utility model relates to industrial cable articles for use and preparing technical field, refers in particular to a kind of cable with the thin strip of PTFE.
Background technology
The insulating barrier that present industrial cable is used roughly has following several kinds: metallic conductor is carried out enamel-cover handle, form enamel insulated wire; A kind ofly in addition coat, form thick insulating barrier or batch clad can through the shedder hot extrude; Also having a kind of is outside conductive surface or functional layer, to twine the thin strip of PTFE to twine lapped insulation or protection processing, uses in space flight equipment, medical equipment or other precision equipment instrument usually.Twine the conductor material after wrapped for the thin material of PTFE, also need pass through 360～420 ℃ of sintering processes, let the thin material of PTFE twine to be fitted in and carry out good insulation performance on the conductor material.
Yet, in the production process of the thin material of PTFE (polytetrafluoroethylene),, after the thin material calendering of PTFE, generally all carry out thermal finalization and handle in order to keep good intensity and toughness; Treatment temperature is generally 340～370 ℃; The melt temperature of PTFE is 327～347 ℃, in type-approval process, has generally surpassed the melt temperature of PTFE; Therefore arrange the arrangement that intermolecular formation is more stable again between the products molecule after the typing.When sintering once more, be difficult to the rock-steady structure combination that forms between the saboteur, the hot melt effect of sintering is relatively poor, can not well twine to be fitted in to carry out good insulation performance or protection on conductor material or the coating layer, has a strong impact on the quality of product.
Yet the thin material of the heat treated PTFE of prepattern is because intensity is relatively poor, and thickness is difficult to control, is difficult in and carries out the use of lapped insulation material on the conductor material.
The utility model content
The utility model is to approach the deficiency that strip exists at wrapped conductor to the cable after the typing at present with PTFE, and provides a kind of cable that overcomes the above problems with the thin strip of PTFE.
For achieving the above object, the utility model adopts following technical scheme:
A kind of cable is with the thin strip of PTFE, and the thin strip of said PTFE is provided with the typing PTFE layer of micropore, in a side of typing PTFE layer prepattern PTFE layer is set.
The opposite side of wherein said typing PTFE layer is provided with also prepattern PTFE layer
Fill unshaped PTFE material in the micropore of wherein said typing PTFE layer.
The beneficial effect of the utility model is: a kind of cable of the utility model is with the thin strip of PTFE, at the thin strip of PTFE the typing PTFE layer of micropore is set, and in a side of typing PTFE layer prepattern PTFE layer is set; Typing PTFE layer is as substrate layer, makes the thin strip of PTFE of the utility model have good intensity and toughness is convenient to processing, behind wrapped conductor; Carry out sintering; Temperature surpasses the melt temperature of PTFE, because the intermolecular adhesion of unshaped PTFE layer is less, and the intermolecular hot melt state freely that is in of unshaped PTFE layer; Micropore through typing PTFE layer; The PTFE layer molecular energy of hot melt effectively makes the thin strip of whole PTFE twine and is fitted in conductor material or insulating material, and shape good insulation performance layer improves the quality of products behind the sintering.

Embodiment
Below in conjunction with accompanying drawing the utility model is done further to set forth:
Embodiment 1, and is as shown in Figure 1, and a kind of cable is with the thin strip of PTFE, and the thin strip of PTFE is provided with the typing PTFE layer 1 of micropore 11, in a side of typing PTFE layer 1 prepattern PTFE layer 2 is set, and in the micropore 11 of typing PTFE layer, fills unshaped PTFE and expect.
Embodiment 2, and is as shown in Figure 2, and a kind of cable is with the thin strip of PTFE; The typing PTFE layer 1 that the thin strip of PTFE is provided with micropore 11 is provided with prepattern PTFE layer 2 as base material in the both sides as typing PTFE layer 1, and in the micropore 11 of typing PTFE layer, fills unshaped PTFE material; The two-sided prepattern PTFE layer 2 that is provided with of base material can effectively strengthen the thin hot melt effect of strip when thermal sintering of PTFE, strengthens the applying ability of the thin strip coiled conductor of PTFE; And the reinforced insulation effect, improve the quality of products.
The utility model cable comprises that with the preparation method of the thin strip of PTFE following technology goes on foot mule:
(1), the PTFE film is carried out micropore stretching and thermal finalization processing;
(2), the base material strip of web-like film is cut and be wound into to step 1 typing PTFE film, the base material strip that cuts into rolling is convenient to following coating operation;
(3), preparation coat raw material: organic solvent is sneaked into formation paste coat raw material in the teflon resin powder; As better organic solvent; Generally select kerosene, naphtha or aviation fuel for use; In the de-oiling operation, need not too high temperature and can these oil plant solvent releases can not caused the too high initiation coat of temperature high-temperature shaping;
(4), with the coat raw material of a coating step of the base material strip in the step 23 configurations, coating method generally can select coating machine to apply or artificial blade coating or other modes apply, and evenly applies to get final product;
(5), the strip of the coat that applies in the step 4 heated de-oiling handle, the de-oiling temperature is 120～230 ℃, effectively de-oiling, and prevent that coat high temperature from causing typing;
(6), step 5 strip is carried out roll-in, the coat material is pressed in the micropore;
(7), the strip of step 6 is cut into the fines band and carry out rolling and process product.
Above operation is the operation of the one-sided coating prepattern of base material PTFE layer; Can also produce the product of two-sided prepattern PTFE layer: the material band individual layer after the step 6 is provided with the strip of coat; Coat raw material in a side coating step 3 configurations of the uncoated coat of base material strip; And repeat the PROCESS FOR TREATMENT of step 5, step 6, carry out the PROCESS FOR TREATMENT of step 7 at last.Just obtain two-sided the utility model product that prepattern PTFE layer faciola shape is set.
In order better the coat material to be pressed in the micropore, in the actual production can also with pass through strip after the step 4 can also carry out step 6 earlier in roll-in, the coat material is pressed in the micropore, and then the de-oiling of carrying out step 5 is handled.
The above embodiment; It is the preferred embodiments of the utility model; Be not to limit the utility model practical range,, all should be included in the utility model patent claim so all equivalences of doing according to the described structure of the utility model claim, characteristic and principle change or modify.
