Definitions
- the present invention relates to a fireproof insulating material for an electric cable, as well as an electric cable obtained using this material.
- Such materials are used in particular for the insulation of electrical conductors providing static connections in a telephone exchange. They must satisfy many conditions of dielectric strength and mechanical strength, especially when hot, and in addition, in the event of a fire in the central, they must on the one hand burn with difficulty, that is to say have an index of high oxygen, and on the other hand, if they burn, do not generate excessively corrosive vapors.
- IOL limiting oxygen index
- the insulating material consists of a matrix formed by an organic polymer and optional additives, in particular flame retardants.
- Crosslinked polyethylene can also be used, but crosslinking requires significant investment if the material is to be extruded at high speed.
- Copolymers of propylene and ethylene, high density polyethylene and thermoplastic polyesters can also be satisfactory in terms of mechanical properties and hot aging, but this type of material like the previous one requires effective fireproofing to be used.
- the original IOL of propylene and ethylene copolymers with a low ethylene content is indeed close to 18, whereas an IOL of 27 should be obtained.
- alumina trihydrate and organic materials containing chlorine or bromine have been used, for example hexabromocyclododecane, tetrabromoethane or halogenated aromatic compounds.
- the object of the present invention is to produce a fire-retardant insulating material for an electric cable which has both a high oxygen index, a low chemical aggressiveness of the vapors given off during combustion, good mechanical and electrical qualities, hot and cold (winding), good resistance to thermal aging and low cost price.
- the flame retardant insulating material according to the invention is characterized in that the synthetic matrix polymer is a member of the group consisting of copolymers of propylene and ethylene, high density polyethylene and thermoplastic polyesters, and in that the flame retardant is a cyclic derivative of pentaerythritol, an aliphatic derivative or a cycloaliphatic derivative, halogenated and stable at the extrusion temperature of the matrix, and decomposing at a higher temperature, and in which at least the majority of the halogenated substituents are bromine atoms.
- the synthetic matrix polymer is a member of the group consisting of copolymers of propylene and ethylene, high density polyethylene and thermoplastic polyesters
- the flame retardant is a cyclic derivative of pentaerythritol, an aliphatic derivative or a cycloaliphatic derivative, halogenated and stable at the extrusion temperature of the matrix, and decomposing at a higher temperature, and in which at least the
- the invention further extends to an electric cable comprising at least one sheath made of a material as defined above, and preferably an internal sheath and an external sheath made of said material, separated by a glass fiber envelope or of mica.
- flame retardant A In the case of a matrix consisting of polypropylene or of a thermoplastic polyester, it will preferably be used as flame retardant 3.9 - bis (2,2 - dibromcmethyl-3 - chloropropoxy) - 2,4,8,10 - tetraoxa -3.9 - diphosphaspiro (5.5) undecane -3.9 - dioxide, which will be designated hereinafter flame retardant A. It will be noted that this compound contains phosphorus in its molecule. The role of phosphorus appears to be to slow the spread of the flame, whether it is incorporated into the molecule of the organic flame retardant or added to it in the form of red phosphorus.
- thermoplastic polyester forming the matrix it is possible in particular to use polybutane-1,4-diol and tetramethylene glycol terephthalate marketed under the trade designation Hytrel by the company DU PONT DE NEMOURS or that marketed under the designation 1010-5 by the KOPPERS Company.
- a mixture of polypropylene and 12.5% by weight of the flame retardant A intimately mixed in a kneader and then subjected to an injection molding, gives an oxygen index IOL of 25.5 to the test according to the American standard ASTMD-2863 of 1970. After adding 0.5 part by weight of 2,3-2,3-dimethyl-diphenylbutane (free radical generator) an oxygen index of 30 is obtained.
- An oxygen index of 27 is generally considered to be very satisfactory.
- a mineral antimony compound such as antimony oxide, should be added to the mixture to fix the bromine, chlorine, hydrobromic acid or hydrochloric acid released by the decomposition of the flame retardant.
- a matrix consisting of a copolymer of propylene and ethylene in which the proportion of ethylene is preferably less than 10% by weight, preferably used as flame retardant 3.9 - bis ( 2,2 - dibromomethyl) - 3 chloro-propoxy) 2,4,8,10 - tetroxa - 3,9 - diphosphaspiro (5,5) undécane-3,9 - dioxide, which will be designated below the flame retardant B, or the hexabromocyclododecane of formula which will be designated below the flame retardant C.
- a mixture of 100 parts of a copolymer of propylene and ethylene with 2.8% of ethylene, of 15 parts of the flame retardant B or C and 10 parts of antimony oxide, added with the known antioxidants and anticoppers necessary for the processing and good aging of the material for example the phenolic derivatives marketed under the names Irganox 10 -10 or 10-76 by the company CIBA GEIGY
- the known antioxidants and anticoppers necessary for the processing and good aging of the material for example the phenolic derivatives marketed under the names Irganox 10 -10 or 10-76 by the company CIBA GEIGY
- Oxygen indices of 24.5 are obtained with the flame retardant B and 29 with the flame retardant C.
- oxygen indices of 25 are obtained when the mixture does not include a free radical generator, and of 31 when 0.4% by weight of 2 is added , 3 - 2,3 - dimethyl - diphenylbutane.
- Drip resistance when required, can be improved by adding carbon black.
- the material can be made cellular by the addition of very fine grains of a chemical compound which decomposes at its extrusion temperature with the release of a gas, in particular azodicarbonamide, and possibly of a nucleating agent.
