Die Erfindung betrifft ein Hitzeschild zur thermischen Abschirmung temperaturempfindlicher Bauteile in Verbrennungskraftmaschinen gegenüber der vom Motor im Betrieb ausgehenden Wärmestrahlung, bestehend aus mit Wärmeisoliermaterial beschichtetem Metallblech oder Metallfolie.The invention relates to a heat shield for thermal Shielding of temperature sensitive components in Internal combustion engines compared to that of the engine in Operation outgoing heat radiation, consisting of with Heat insulating material coated metal sheet or Metal foil.

Bei Verbrennungskraftmaschinen können sich im Betrieb benachbart zu den heißgehenden Motorteilen angeordnete Bauteile durch die vom Motor ausgehende Wärmeabstrahlung überhitzen. Temperaturempfindliche elektrische oder elektronische Bauteile oder die Kraftstoffleitungen können bei Überhitzung ausfallen, und es kann dann zum Ausfall des gesamten Motors kommen.Internal combustion engines can be in operation arranged adjacent to the hot engine parts Components from the engine Overheat heat radiation. Temperature sensitive electrical or electronic components or the Fuel lines can fail in the event of overheating, and then the entire engine may fail come.

Es ist daher in der Praxis bekannt, solche temperaturempfindlichen Bauteile vor der Wärmeeinstrahlung besonders zu schützen, indem man die Bauteile mit Hitzeschildern abschirmt. Als Material dafür verwendet man herkömmliche Wärmeisolierplatten oder mit Wärmedämmstoffen belegte Aluminiumfolien oder -bleche.It is therefore known in practice to do so temperature sensitive components before To protect heat radiation especially by the Shields components with heat shields. As a material conventional thermal insulation panels are used for this or aluminum foils covered with thermal insulation materials or -sheets.

Nach der DE-OS 19 62 625, dem DE-GM 87 09 034, dem DE-GM 87 05 294, der EP-PA 03 42 661, der GB-PS 20 81 643, der US-PS 32 31 401, der DE-OS 23 00 724, nach Automobiltechnische Zeitschrift 90 (1988), Seite 108 und der JP-PA 1 63 947 bestehen derartige Schallisolationsstoffe und Wärmeisolationsstoffe aus porösen Platten oder Formkörpern mit anorganischen Fasern und/oder pulverigen bis feinkörnigen Füllstoffen mit anorganischen Bindemitteln. Die Platten oder Formkörper können dabei mit beidseitig aufgespritzten, galvanisch abgeschiedenen oder aufgeklebten Metallschichten versehen sein. Nach der US-PS 26 14 055, der US-PS 20 36 913 und der JP-PA 1 65 841 verwendet man für Schallisolationszwecke oder Wärmeisolationszwecke Glimmerplattenmaterial aus Gemischen von Glimmerpulver mit anorganischen oder organischen Bindemitteln, die gegebenenfalls auch durch Imprägnieren in Glimmerplattenmaterial eingebracht sein können.According to DE-OS 19 62 625, DE-GM 87 09 034, the  DE-GM 87 05 294, EP-PA 03 42 661, GB-PS 20 81 643, US-PS 32 31 401, DE-OS 23 00 724, according to automotive engineering magazine 90 (1988), Page 108 and JP-PA 1 63 947 exist Sound insulation materials and heat insulation materials porous plates or moldings with inorganic Fibers and / or powdery to fine-grained Fillers with inorganic binders. The Plates or moldings can be used on both sides sprayed on, galvanically deposited or glued metal layers. After US-PS 26 14 055, the US-PS 20 36 913 and the JP-PA 1 65 841 is used for sound insulation purposes or Mica sheet material for thermal insulation purposes Mixtures of mica powder with inorganic or organic binders, if appropriate also by impregnation in mica sheet material can be introduced.

Hitzeschilder in Verbrennungskraftmaschinen sind im Fahrbetrieb außer den Temperaturbelastungen auch den Schwingungsbelastungen durch den Motor und den Fahrbetrieb ausgesetzt, und zusätzlich wird von ihnen eine hohe Dauerbeständigkeit bei erhöhter Temperatur sowie eine Beständigkeit gegenüber Motorenölen und eine ausreichende Widerstandsfähigkeit gegenüber beispielsweise einer Motordampfstrahlwäsche verlangt. Hinzu kommen noch die Anforderungen einer leichten Montierbarkeit und eines möglichst niedrigen Gewichtes. Die herkömmlichen porösen Wärmeisolierplatten oder mit Wärmedämmstoffen belegten Metallplatten erfüllen nicht alle diese Bedingungen zugleich und werden nach längerer Betriebsdauer insbesondere an ihren Klebstellen zerstört, oder sie sind so teuer, daß ihr Einsatz unwirtschaftlich ist.Heat shields in internal combustion engines are in the Driving operation in addition to the temperature loads Vibration loads from the engine and the Suspended driving, and in addition, by them high durability at elevated temperatures as well as resistance to engine oils and sufficient resistance to for example, an engine steam jet wash. In addition, there are the requirements of an easy one Mountability and the lowest possible  Weight. The conventional porous Thermal insulation panels or covered with thermal insulation materials Metal plates do not meet all of these conditions at the same time and become after a long period of operation destroyed especially at their glue points, or they are so expensive that their use is uneconomical.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein Hitzeschild gemäß Oberbegriff des Hauptpatentanspruches zu schaffen, welches wirtschaftlich herstellbar ist, und welches die geforderten technologischen Eigenschaften erfüllt.The present invention is therefore the object based on a heat shield according to the preamble of To create main patent claim, which is economically producible, and which the required technological properties.

Erfindungsgemäß wird diese Aufgabe durch ein aus einem Metallblech oder einer Metallfolie bestehendes Hitzeschild gelöst, dessen ein- oder beidseitige Beschichtung aus einem wasserlöslichen Natrium- oder Kaliumsilikat und einem anorganischen Füllstoff aus Glimmerpulver besteht, wobei die Beschichtung auf dem Metallblech oder der Metallfolie eingebrannt ist.According to the invention, this object is achieved by an out of one Metal sheet or a metal foil existing Heat shield released, the one or both sides Coating from a water-soluble sodium or Potassium silicate and an inorganic filler Mica powder exists, the coating on the Metal sheet or the metal foil is baked.

Die verwendeten Metallbleche oder -folien bestehen bevorzugt aus Aluminium, und die wasserfreie getrocknete Schicht enthält bei einer bevorzugten Schichtdicke zwischen 0,05 und 0,2 mm zwischen 25 und 75 Gewichtsprozent Alkalisilikat und entsprechend zwischen 25 und 75 Gewichtsprozent Glimmerpulver.The metal sheets or foils used exist preferably made of aluminum, and the anhydrous one layer contains dried layer Layer thickness between 0.05 and 0.2 mm between 25 and 75 percent by weight alkali silicate and corresponding between 25 and 75 percent by weight of mica powder.

Zur Herstellung des erfindungsgemäßen Hitzeschilds kann die wäßrige, mit Füllstoff versetzte Wasserglassuspension relativ einfach im Spritz-, Druck-, Walz-, Rakel- oder Coil-Coating-Verfahren auf die Metallplatten oder Metallfolien aufgetragen werden. Nach dem Verdampfen des Wassers erfolgt dann das Einbrennen der Schicht während etwa 2 bis 6 Minuten bei Temperaturen von etwa 300°C. Dabei entsteht eine feste, nicht gesinterte, elektrisch nur schwach leitende Beschichtung auf den Metallfolien oder Metallblechen.To produce the invention  Heat shields can be aqueous, with filler offset water glass suspension relatively easy in Spraying, printing, rolling, knife or Coil coating process on the metal plates or Metal foils can be applied. After evaporation the water is then burned into the layer for about 2 to 6 minutes at temperatures of about 300 ° C. This creates a solid, not sintered, electrically only weakly conductive coating on the Metal foils or metal sheets.

Aus den beschichteten Metallblechen oder Metallfolien werden dann die Hitzeschilder bevorzugt durch Stanzen oder Schneiden hergestellt, und ihr Verhalten wurde getestet. Die Verarbeitbarkeit des Materials ist gut. Das Material läßt sich sowohl unproblematisch stanzen oder schneiden, und es ist ohne Schichtabplatzungen so weit verformbar, daß es zu die zu schützenden Bauteile umhüllenden Hitzeschildern gebogen werden kann.From the coated metal sheets or metal foils the heat shields are then preferred by stamping or cutting, and their behavior became tested. The processability of the material is good. The material can be punched without any problems or cut, and it's like this with no chipping widely deformable that it is the components to be protected enveloping heat shields can be bent.

Die Temperaturbelastbarkeit liegt in Abhängigkeit von der eingesetzten Füllstoffmenge im Bereich zwischen etwa 600 und 1100°C. Dadurch kann das erfindungsgemäße Hitzeschild praktisch an allen Stellen des Motors einschließlich zur Abschirmung der Zündkerzen, Zündkerzenstecker und Zündkabel im Auspuffkrümmerbereich eingesetzt werden. Die Wärmeleitfähigkeit des Hitzeschildes ist dabei gering, und über das Metallblech kann nach außen Wärme abgeführt werden.The temperature resistance depends on the amount of filler used in the range between about 600 and 1100 ° C. This can Heat shield according to the invention practically on all Place the motor including to shield the Spark plugs, spark plug connectors and ignition cables in the Exhaust manifold area can be used. The The thermal conductivity of the heat shield is low, and the metal sheet can heat outside  be dissipated.

Auch bei Dauerbelastung weist das Hitzeschild unter Schwingungsbelastung keine Schichtabplatzungen auf, und Materialversprödungen oder Quellungen durch Motorenöle oder Wasserdämpfe auch bei erhöhten Temperaturen wurden nicht beobachtet.The heat shield provides instruction even under permanent load Vibration exposure no shifting and embrittlement or swelling Motor oils or water vapors even with increased Temperatures were not observed.

In Motorversuchen konnten diese guten Ergebnisse bestätigt werden, wobei auch bei starken Überhitzungen des Motors die abgeschirmten elektrischen und elektronischen Bauteile sowie Kraftstoffleitungen keinerlei Ausfallserscheinungen aufwiesen.These good results were achieved in engine tests be confirmed, even with severe overheating of the motor the shielded electrical and electronic components and fuel lines showed no signs of failure.

Durch die Erfindung ist somit ein wirtschaftlich herstellbares Hitzeschild gefunden, das gut verarbeitbar ist, und welches auch nach Dauerbelastung mit guter thermischer Abschirmung zerstörungsfrei arbeitet. Auch aufgrund seines leichten Gewichtes ist das Hitzeschild vor allem in Verbrennungskraftmaschinen einsetzbar.The invention thus makes it economical manufacturable heat shield found that good is processable, and which even after permanent exposure with good thermal shielding, non-destructive is working. Also because of its light weight the heat shield especially in Internal combustion engines can be used.

Im Sinne der Erfindung ist das Hitzeschild aber auch in anderen Bauteilen bei ähnlichen Belastungen zur thermischen Isolation und Abschirmung anwendbar. Während bevorzugt das erfindungsgemäße Hitzeschild ein- oder beidseitig ganzflächig beschichtet ist, ist es auch möglich, die Metallbleche oder -folien nur teilflächig zu beschichten, so daß beispielsweise über die nach außen überstehenden freien Metallflächen Wärme nach außen abgeleitet werden kann.For the purposes of the invention, however, the heat shield is also in other components with similar loads thermal insulation and shielding applicable. While preferred the invention Full-surface heat shield on one or both sides is coated, it is also possible to use the metal sheets to coat only partially or foils so that  for example, those that protrude outwards free metal surfaces dissipate heat to the outside can be.
