Natriumcarbonat, Aluminium- oder Magnesiumhydroxid in Pulverform einzeln und in entsprechenden Gemischen und mit einem Füllgradspektrum von 10 bis 80 sowie mit einem Korngrößenspektrum von 10 bis 300 μm lassen sich diese Materialgemische in die organischen Polyurethankomponenten ( Polyole und Isocyanate ) direkt einmischen und verschäumen.As a result of extensive studies on the Optimization of the recipe proportion of these heat-conducting particles, preferably Russian, Graphite, aluminum powder, aluminum oxide, iron and silicate Particles became so cheap Thermal conductivity values for the final product (Sandwich element) found that on other thermally conductive materials or Elements (e.g. aluminum foil) can be dispensed with. Together with the known flame retardants such as Sodium, Aluminum or magnesium hydroxide in powder form individually and in corresponding Mix and with a degree of filling from 10 to 80 and with a grain size range from 10 to 300 μm these material mixtures into the organic polyurethane components Mix in (polyols and isocyanates) directly and foam.

Durch eine entsprechend angepasste Misch- und Dosiertechnik ist so in einem einzigen technologisch durchgehenden Gieß- und Aufschäumvorgang die Herstellung montagefertiger Heizelemenf-Module in einer Gießform oder auf einem Fließband möglich.By an appropriately adapted Mixing and dosing technology is technological in one continuous casting and foaming the Manufacture of ready-to-install heating element modules in a mold or on an assembly line possible.

Die Zeichnung zeigt den mit Hilfe der verbesserten Technologie herstellbaren, efindungsgemäßen, wesentlich vereinfachten Schichtaufbau des Heizelementes in Sandwichbauweise.The drawing shows that with the help the improved technology that can be produced, according to the invention, is essential Simplified layer structure of the heating element in sandwich construction.
