- Another object of the present invention is to provide a new covering or coating composition for use with ignition cable constructions or for other uses.
- FIG. 1 illustrates in perspective using cut-away portions, an ignition cable construction in accordance with the invention.
- the present invention concerns an ignition cable means having an improved construction comprising a flexible resistive conductor means for conducting electrical current to provide ignition, a flexible conductive coating means generally surrounding the resistive conductor means, said coating being made from a composition comprised of about 50 percent to about 90 percent by weight of fluoroelastomer means for providing the coating with sustained thermal stability for continuous exposure to temperatures of about 500F., and for shorter term exposure to temperatures of 600650F., about percent to about 50 percent by weight of conductive pigment means for providing conductivity to the coating, and zero to about percent by weight of flow control agent means for facilitating application usage of the coating, and said coating including about l percent to about 50 percent by weight total solids of the above in a solvent carrier.
- the invention also concerns a novel coating composition or covering material wherein through the unique combination of a fluoroelastomer material capable of resisting high temperatures and a special pigmentation means such as a conductive pigment or a fluorocarbon pigment, a highly useful product is obtained.
- FIG. .1 illustrates an ignition cable construction designated 10 which is comprised of graphite impregnated fiberglass conductors 12, a braid material 14 of rayon, cotton or the like woven around the elements 12 to hold same together. and a special covering material or coating composition 16 surrounding the core of the ignition cable formed by the conductors l2 and braid 14.
- the covering material or sheath 16 is a high temperature resistant special electrically conductive layer and will be described in more detail below.
- a strip coating 18 formed for example of a material which includes graphite.
- the strip coating 18 is optional. It may be used for the function of allowing a conventional overlying insulating material 20, further braid material 22 and insulating jacket 24 to be readily stripped or removed from the nonmetallic conductor means so that electrical connections with a terminal can be made as desired. It is to be understood that the strip coating, insulating layer and/or the insulatingjacket, as well as the braiding layers can be made from any number of different materials so long as they are suitably resistant to high temperature and so long as they do not detrimentally effect the necessary electrical properties of the ignition cable construction.
- the crux of the ignition cable construction in accordance with this invention lies in the enveloping of the flexible conductors 12 within the special covering or coating sheath 16.
- the braid material 14 may be applied prior to or subsequent to the application of the covering sheath 16, however, preferably the braid material 14 is applied to the flexible conductors 12 before the covering 16 is applied.
- the covering or coating 16 is applied to envelop the flexible conductors 12 using a suitable applicator which coats the covering 16 onto the ignition cable from a solvent solution with the solvent later being driven off or evaporated from the coating or layer 16.
- a suitable applicator which coats the covering 16 onto the ignition cable from a solvent solution with the solvent later being driven off or evaporated from the coating or layer 16.
- the coating or layer 16 is applied to the cable by dipcoating the cable in a solution of the coating which is maintained within the borad range of approximately about ZOO-5,000 centipoise and preferably within the range of about 5002,000 centipoise.
- the coating composition for forming the layer 16 contains total solids within the broad range of about 96 percent to about percent by weight of the total weight of the coating composition and preferably the percent solids is maintained within the range of about /2 percent to about 20 percent by weight.
- the fluoroelastomer material means used in the coating should be present within the broad range of about 8 percent to about 95 percent by weight of the coating solids and preferably from about 50 percent to about percent by weight, with best results being obtained in the range of 60-80 percent.
- This fluoroelastomer material provides the special function of endowing the coating with high temperature resistance or great thermal stability, that is, resistance to temperatures in excess of 400F. and, particularly this temperature resistance has been found to be effective and operative within the range of about 400F. up to about 600F. and higher.
- the fluoroelastomer material used in the invention should be one which provides this high temperature resistance and which is also sufficiently flexible for use in ignition cable constructions while at the same time possessing the property of being able to operate as an effective binder material for the applied coating.
- Particularly suitable material for use as the fluoroelastomer herein may be described as vinyl/olefinic fluoroelastomeric polymers, vinyl-fluorocarbon elastomeric copolymers, vinylidene/fluoro-olefinic elastomeric polymers, and C -C olefinic/fluorocarbon elastomeric copolymers.
- a preferred material is the vinylidene fluoride/hexafluoropropene copolymer fiuoroelastomer.
- Commercially available fiuoroelastomers which may be used are Viton (DuPont trademark) and Fluorel (3M Company trademark).
- Still further fluoroelastomers which may be used herein are described in U.S. Pat. Nos. 2,968,649, 3,051,677, and 3,172,124, the disclosures of which are incorporated herein by refcrcncc.
- the pigment means or particles for use in the coating 1 16 should be present within the broad range of about 5 percent to about 92 percent by weight of the total solids of the coating and preferably this range should be from about percent to about 50 percent by weight, with best results being obtained in the range of 20-40 percent.
- Particularly suitable pigments for use in the coating are various finely particulated pigments such as graphite, conductive carbon black, silver particles, copper particles, noble metal particles, tin oxide, and fluorocarbon polymer particle pigments.
- Particularly suitable conductive pigments are finely divided graphite, silver and, copper particles.
- the fluorocarbon pigment particles add lubricity to the finished coating.
- the flow control agent used in the coating may be present broadly within the range of zero up to about percent by weight of the coating solids and preferably the flow control agent is present in the range of about 0.05 percent up to about 10 percent by weight of the coating solids.
- Particularly suitable materials for use as the flow control agent are finely divided materials selected from the group consisting of silicas, finely di-' vided clays, and silicates. Specific materials for this case are Cab-o-sil and Bentone.
- the solvent or carrier material used for forming a fluid dispersion of the coating solids may satisfactorily be selected from any number of different solvents such as methyl-ethyl ketone, acetone, various other ketone type solvents, dimethylformamide, and numerous other organic solvent materials.
- the solvent forms the balance of the coating composition when the coating is formulated in a solution having a total solids content between about k percent and 50 percent by weight solids as referred to above.
- the solvent is essentially driven off or evaporated leaving the applied coating.
- a curing agent may also optionally be used in the coating although it is not preferred.
- various amino type curing agents and the like may be used.
- the continuous operating temperature for coatings formed in accordance with the above is about 500F.
- coatings withstand temperatures as high as about 600650F and higher.
- coatings so formed are highly useful in under-the-hood applications for the newly specified automotive engine requirements, where under-the-hood temperature specifications for automotive usage are in excess of 400F.
- under-the-hood temperature specifications for automotive usage are in excess of 400F.
- specifications for such under-thehood applications require that ignition cable constructions be operative at temperatures in excess of 400F. for sustained periods of time.
- Coating compositions suitable for use in manufacture of thermally stable ignition cables are prepared by dispersing the graphite or conductive carbon particles in solutions of the selected fluoroelastomer.
- the amount of solvent used should be suflicient to provide a suitable dispersing medium for the solid particles.
- the particlesv may be dispersed in all or part of the elastomer solution, for example by means such as use of ball or pebble mills, double blade mixers, or impeller mixers. Adjustment of the consistency of the composition to that suitable for application to the cable may be effected by such means as adjusting the proportion of solvent, adjusting the temperature, or incorporating a bodying agent or flow control ingredient in suitable amount.
- the electrical resistance of the coating formed in the ignition cable structure is determined by the coating thickness, by the particular conductive particles used, and the ratio of conductive particles to elastomer, i.e., the pigment: binder ratio. The exact level selected will be dependent on the core resistance as well as on other characteristics of the cable, such as the elastomer covering, the dimensions, etc. Generally, coatings in the resistance range between 500 ohms and 30,000 ohms per square, as evaluated by the technique herein described, can be adapted to produce ignition cables having desirable electrical characteristics.
- Resistance character of coating compositions can be evaluated by forming dried or cured coatings under uniform conditions, upon which the electrical resistance measurements can be made. It is convenient to deposit the coatings from compositions containing about 13.5 percent total solids by use ofa blade coating device which will form on a glass plate layers of predetermined thickness. Measurements herein have been made at a dry coating thickness of 0.0005 inch, after curing for 10 minutes at 300F.
