Description
(54) INSULATED ELECTRICAL CONDUCTOR
(71) We, INTERNATIONAL STANDARD ELECTRIC CORPORATION a corporation organised and existing under the laws of the State of Delaware, United States of
America, of 320 Park Avenue, New York 22, State of New York, United States of America, do hereby declare the invention for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement:
This invention relates to an insulated electrical conductor having a two-layer crosslinked polymeric coating.
The performance requirements at elevated temperatures of insulated wires are becoming increasingly more demanding. For certain military requirements, the insulating properties of polyethylene are excellant. However, at elevated temperatures, the polyethylene undergoes thermal oxidative degradation. A second polymeric coating, of e.g. polyvinylidene fluoride, has been used to protect the polyethylene from thermal degradation, but while this has provided a certain measure of protection. the elevated temperature properties of such insulated conductors are still not acceptable for many of the more demanding insulation requirements.
Other fluorocarbon polymers useful as wire insulation are known, including copolymers of ethylene and chlorotrifluoroethylene. However, the elevated temperature properties, and particularly the deformation resistance of the latter copolymers are not significantly different than those of polyvinylidene fluoride. There has therefore been a continuing need for an improved jacketing insulation for polyethylene coated wire.
We have now discovered that considerably improved elevated temperature properties are achieved in an insualted electrical conductor comprising a primary coating of a crosslinked polyolefin jacketed in a crosslinked copolymer of ethylene and chlorotrifluoroethylene containing from 1 to 10%, preferably 2 to 6% of certain crosslinking coreactants and from 1 to 10%, preferably 2 - 5% of certain stabilizers. Such insulated conductors equal or surpass the military specifications for insulated electrical wire for continued operation at temperatures as high as 150"C. In addition, such insualated conductors also have excellent subambient or low temperature properties. The invention is specific to the use of ethylene/chlorotrifluoroethylene copolymers.Equivalent results are not obtained with other chemically similar fluorocarbon polymers, including for example, copolymers of ethylene and tetrafluoroethylene.
The outer or jacketing layer contains, in addition to the fluorocarbon copolymer, a crosslinking coreactant and a stabilizer. The crosslinking coreactants used possess high temperature stability, and are not prone to polymerization at elevated temperatures and especially during extrusion processing. The useful crosslinking coreactants used possess high temperature stability, and are not prone to polymerization at elevated temperatures and especially during extrusion processing. The useful crosslinking coreactants are selected from the group consisting of (a) diallyl, dimethyallyl and triallyl esters of aryl polycarboxylic acids, (b) diallyl and dimethallyl esters of alkyl, cycloalkyl and aralkyl dicarboxylic acids, (c) dimethacrylate glycol esters and (d) blends of said crosslinking coreactants.The stabilizer is selected from the group consisting of alkaline earth metal oxides and lead salts. Suitable stabilizers are, for example, basic lead silicate, lead phthalate, magnesium oxide and calcium oxide.
Diallyl and dimethallyl esters of aryl polycarboxylic acids useful as crosslinking coreactants are typified by the diallyl and dimethyallyl esters of sulfonyl dibenzoic acid and the diallyl ester of 4,4'- dicarboxydiphenyl ether. The use of the diphenyl ethers as crosslinking coreactants is more fully disclosed in U.S. Patent 3,970,770. The triallyl esters of aryl polycarboxylic acids useful as a crosslinking coreactant are typified by triallyl trimesate and triallyl mellitate.
The use of these and other triallyl esters as crosslinking coreactants for fluorocarbon polymers is more fully disclosed in U.S. Patent 3,840,619. Typical diallyl and dimethallyl esters of alkyl dicarboxylic acids useful in the present process are the diallyl and dimethallyl esters of dodecandioic and brassylic acid. These and other useful esters of alkyl and cycloalkyl dicarboxylic acids are disclosed in U.S. Patent 4,051,003. Useful diallyl and methallyl esters of aralkyl dicarboxylic acids are the esters of phenyl indan and these esters are more fully disclosed in U.S. Patent 3,839,261. A preferred dimethacrylate ester is decamethylene glycol dimethacrylate. The dimethacrylate esters are preferably esters of a glycol containing at least 10 carbon atoms, as more fully disclosed in U.S. Patent 3,894,118.Reference to the foregoing patents should be made for a more complete description of the crosslinking coreactants.
The use of stabilizers with fluorocarbon polymers is known. However, the presence of the foregoing stabilizers in the extruded fluorocarbon coatings of the present products is unique in that many fluorocarbon polymers can't be successfully extruded when such stabilizers are present. It has been found that copolymers of ethylene and chlorotrifluoroethylene can be extruded with these stabilizers and that the resultant dual coating on wire forms an insulated wire of outstanding high temperature properties.
The copolymers useful as the jacketing layer are alternating copolymers of ethylene and chlorotrifluoroethylene having a mole ratio of monomeric units ranging from 40/60 to 60/40. Such copolymers and their use in irradiation crosslinked form as wire coatings is shown in U.S. Patent Re. 28628 and reference to that patent should be made for a more complete description of the copolymers and their preparation. The polyolefin coating is preferably polyethylene and even more preferably high density polyethylene. The polyethylene primary coating may optionally contain up to 60% of chlorinated polyethylene and in addition flame retardant agents such as antimony oxide, antioxidants and known polyethylene crosslinking agents.
In preparing the insulated wires of the invention, a powder blend of each of the polymeric coatings is prepared, rod extruded, pelletized and extruded onto wire. The polyolefin coating is extruded onto wire at temperatures of about 1700 to 182"C. The copolymeric jacketing material is rod extruded at 230"C to 2500C. and extruded onto wire at 270 to 300"C. The coated wire is then subjected to irradiation of from about 1 to 25 megarads with high energy electrons employing standard techniques.
The following examples illustrate the practice of the invention. Unless otherwise indicated, all parts are by weight.
