Definitions
- the invention relates to self-regulating cables of any structure in which the material having a PTC behavior, that is to say having a positive temperature coefficient, is an alloy of compatible polymers.
- the invention also relates to the method for manufacturing self-regulating cables in which the alloy with PTC behavior is implemented by extrusion without an additional crosslinking or heat treatment step around electrically conductive strands.
- the self-regulating cables currently on the market are of two types: either of the polyethylene type or of the fluoropolymer type as described in patent EP 40,537.
- self-regulating cables of the polyethylene type must be crosslinked, or else, as described in US Pat. No. 3,861,029, they must undergo an additional heat treatment of the annealed type, which increases their cost.
- Self-regulating cables of fluoropolymer type have the disadvantage of being fragile and of being of high cost.
- This self-regulating cable is characterized by the fact that the ma- material with PTC behavior is an alloy of compatible polymers comprising, the percentages being expressed by weight relative to the weight of said polymers:
- matrix polymer chosen from the group comprising poly (C ⁇ -C 4 alkylene) terephthalates, polyamides , polypropylenes, polycarbonates, copolymers of polyester and polyether, polyketones and polymethyl methacrylates,
- conductive fillers such as carbon black
- alloy of compatible polymers means a mixture of at least two polymers which are immiscible but which are compatible or a mixture of at least two polymers which are immiscible and not compatible but which are made compatible by addition of a compatibilization agent.
- the polar polyolefin used in the composition of the alloy with PTC behavior is very little crystalline.
- it is an elastomer and it is chosen from copolymers of ethylene / vinyl acetate, ethylene / alkyl acrylate C ⁇ ⁇ C 4 , or mixtures thereof. More preferably, an ethylene / ethyl acrylate or ethylene / methyl acrylate copolymer is used.
- CTP is chosen from polypropylenes, polyesters, and aliphatic polyketones, polyamides, polycarbonates, polyester and polyether copolymers or mixtures thereof.
- this polymer is a polyester, it is preferred to use poly (C 1 -C alkylene) terephthalates, such as polybutyleneterephthalate or polyethyleneterephthalate.
- polybutylene terephthalate is preferred.
- Examples of aliphatic polyketone include that marketed by SHELL under the CHIME ® brand and under the BP KETONEX ® brand. This matrix polymer has a high melting temperature, this melting temperature determining the maximum temperature for using the cable according to the invention.
- the polymer is generally crystalline with the exception of polyethylene terephthalate, which can be used in the present invention in crystalline or amorphous form.
- the alloy with PTC behavior can incorporate various additives, for example antioxidants and non-conductive fillers.
- additives for example antioxidants and non-conductive fillers.
- the choice of additives will of course depend on the end use envisaged for the self-regulating cable according to the invention.
- the conductive filler is preferably carbon black.
- any other electrical charge can be used alone or as a mixture, in particular with carbon black.
- the self-regulating cable according to the invention has an excellent ratio of the starting current intensity to the nominal current intensity and an excellent linear power as well as quite satisfactory aging characteristics.
- the self-regulating cables according to the invention have the following characteristics:
- FIG. 1 represents an exploded view of a self-regulating cable according to the invention
- FIG. 2 represents the curves of the linear power as a function of the temperature of a self-regulating cable according to the invention and of a self-regulating cable of the prior art
- FIGS. 3 and 4 represent photographs by electron microscopy showing the composite structure of the material of an alloy of compatible polymers used in a PTC cable according to the invention, after extraction of the polar olefin, at magnifications 1250 and 640 respectively.
- the self-regulating cable 1 consists of two strands 2 of wires 3 of nickel-plated copper. These strands are parallel to each other and arranged longitudinally in the cable 1 along the two opposite edges thereof. These strands are held in position by extrusion around them of a ribbon 4 made of an alloy of compatible polymers with PTC behavior as described above. Around this strip 4 is extruded a layer 5 of insulating material, such as flame retardant polypropylene or ethylene chlorotrifluoroethylene. A sleeve 6 consisting of a metal braid is placed around the layer 5 of insulating material. The whole is protected by an external insulating sheath 7.
- the mixture therefore comprises approximately 8% by weight of carbon black.
- the ribbon 4 thus obtained has the following characteristics:
- a 60/40 polyethylene-ethylene / ethyl acrylate mixture was extruded around two strands of copper wire and was then crosslinked.
