Description
Hydrophobierte Isoliermasse Waterproofing insulating compound
Die Erfindung betrifft eine hydrophobierte Isoliermasse gemäß dem Oberbegriff des ersten Anspruchs.The invention relates to a hydrophobic insulating compound according to the Preamble to the first claim.
Bei einer bekannten hydrophobierten Isoliermasse für Heizspiralen in Rohrheizkörpern (DE-AS 15 40 902) ist einem feingekörnten anorganischen, oxydischen oder silikatischen Material Dimethyldiäthyoxysilan in flüssiger Form beigegeben.In a known hydrophobic insulating compound for heating coils in tubular heating elements (DE-AS 15 40 902) is a fine-grained inorganic, oxidic or silicate material Dimethyldiäthyoxysilan added in liquid form.
Es ist aber auch bekannt, einer entsprechenden Isoliermasse körniges Alkyl - bzw. Arylpolysiloxan beizumischen. Diese bekannten hydrophobierenden Additive etnhalten organische Stoffe, und sind nicht dauerhaft temperaturbeständig bzw. verteilen sich nicht ausreichend auf dem Substrat oder benetzen es nicht zufriedenstellend.But it is also known to use a corresponding granular insulating compound Mix in alkyl or aryl polysiloxane. These known hydrophobic additives They contain organic substances and are not permanently temperature-resistant or distribute do not settle sufficiently on the substrate or do not wet it satisfactorily.
Der Erfindung liegt die Aufgabe zugrunde, eine Isoliermasse gemäß dem Oberbegriff des ersten Anspruchs anzugeben, die auf einfachste Weise vor nachteiligen Wirkungen von in das Mantelrohr eindringender Feuchtigkeit auch über einen langen Zeitraum geschützt ist.The invention is based on the object of providing an insulating compound according to to indicate the preamble of the first claim, the disadvantageous in the simplest way Effects of moisture penetrating into the jacket pipe also over a long period of time Period is protected.
Die Lösung dieser Aufgabe erfolgt gemäß der Erfindung durch die kennzeichnenden Merkmale des ersten Anspruchs.The solution to this problem takes place according to the invention by the characterizing Features of the first claim.
Die gemäß der Erfindung ausgebildeten Titanverbindungen sind in der Lage, durch monomolekulare Belegung mit den Oberflächen der Körner der Isoliermasse eine chemische Reaktion einzugehen, so daß unter Denatuierung der ursprünglich hydrophilen Oberfläche anschließend die hydrophoben Glieder des Titanates das Eigenschaftsbild bestimmen. Eine mangelhafte Benetzung der Oberfläche des Isoliermaterials ist infolge der Affinität zu beispielsweise Hydroxylgruppen des Substrates geradezu ausgeschlossen, da mit diesen die erwähnte chemische Reaktion eintritt. Es findet somit rundum eine Ankopplung des Titanates an die Körner der Isoliermasse statt.The titanium compounds formed according to the invention are able, through monomolecular coating with the surfaces of the grains of the insulating compound enter into a chemical reaction, so that with denaturation of the originally hydrophilic Then the hydrophobic members of the titanate surface the property profile determine. Inadequate wetting of the surface of the insulating material is the result the affinity to, for example, hydroxyl groups of the substrate is almost impossible, because with these the mentioned chemical reaction occurs. There is one all around Coupling of the titanate to the grains of the insulating compound takes place.
Besonders bewährt haben sich Titanat-Verbindungen die Alkoxigruppen sowie langkettige Carbonsäuregruppen, Acrylsäuregruppen, partiell organisch veresterte Phosphor-bzw. Pyrophosphorsäuregruppen oder partiell organisch veresterte Gruppen der phosphorigen Säure tragen nach der allgemeinen Formel R - 0 - Ti - (OR')3 Die in der Formel angegebenen Radikale R oder R' sind vom Isopropyl-, Lauryl- oder Myricylalkohol abgeleitet, der Rest der Stearinsäure, Isostearinsäure, Acrylsäure, Diiooctylester der Phosphor- bzw. Pyrophosphorsäure bzw.Titanate compounds, the alkoxy groups, have proven particularly useful as well as long-chain carboxylic acid groups, acrylic acid groups, partially organically esterified Phosphorus or Pyrophosphoric acid groups or partially organically esterified groups of phosphorous acid carry according to the general formula R - 0 - Ti - (OR ') 3 Die Radicals R or R 'indicated in the formula are from isopropyl, lauryl or myricyl alcohol derived, the remainder of stearic acid, isostearic acid, acrylic acid, diiooctyl ester of phosphoric or pyrophosphoric acid or
der phosphorigen Säure oder ein substituierter Benzolsulfonsäureester. Bei der Verarbeitung wird das Titanat auf dasfluldisierteanorganische Substrat als reine Flüssigkeit bzw. als organische Lösung aufgebracht. Dabei kann das Substrat bereits vor dem Einfüllen in das Mantelrohr des Rohrheizkörpers oder bei rocken in das Mantelrohr eingefülltem Substrat auf die offenen Enden aufgetropft werden.phosphorous acid or a substituted benzenesulfonic acid ester. In processing, the titanate is applied to the powdered inorganic substrate as a pure liquid or applied as an organic solution. The substrate can before filling into the jacket pipe of the tubular heater or when rocking in the jacket tube filled substrate are dripped onto the open ends.
Nach dem Aufbringen des Titanates wird die imprägnierte Isoliermasse einer Temperaturbehandlung im Mantelrohr unterzogen, in deren Verlauf die Temperatur.auf 3000C gesteigert werden kann. Das Titanat wird in einer Menge von 0,1 Ges.; bis 2 Gew.%, vorzugsweise 0,5 bis 1 Gew.% der jeweils zu hydrophobierenden Substratmenge beigemischt. Vorwiegend eine Isopropoxigruppe des Titanates reagiert bei der Hydrophobierung mit der Füllstoffoberfläche, während z.B.die langkettigen Kohlewasserstoffreste der Stearinsäure das hydrophobe Verhalten bedingen. Ein r Magnesiumoxid mit einer Coatung aus Isopropoxitriisostearoyl-titanat hatte z.B. in eier wasserdampfgesättigten Atmosphäre bei 20 0C nur eine asymptotische Gewichtszunahme von 0,5%.After the titanate has been applied, the impregnated insulating compound is applied subjected to a temperature treatment in the jacket tube, in the course of which the Temperatur.auf 3000C can be increased. The titanate is used in an amount of 0.1 Ges .; until 2% by weight, preferably 0.5 to 1% by weight, of the amount of substrate to be hydrophobized in each case mixed in. Mainly an isopropoxy group of the titanate reacts during the hydrophobization with the filler surface, while e.g. the long-chain hydrocarbon residues of stearic acid cause the hydrophobic behavior. A r magnesium oxide with a Coating of isopropoxitriisostearoyl-titanate had e.g. in eggs saturated with water vapor Atmosphere at 20 0C only an asymptotic weight increase of 0.5%.
In besonderer Ausbildung der Erfindung kann zwecks Feinstverteilung des Coatungsmittels auf den Isolierstoffkörnern eine Aufbringung aus Lösung/Dispersion erfolgen. Ein zusätzliches Erhitzen des gecoateten Füllstoffs auf 2000C bes-chleunigt die Kopplungsreaktion und sichert durch Abtreiben des Hydrolyseproduktes, z.B. Isopropylalkohol, eine höhere Temperaturbeständigkeit.In a special embodiment of the invention, for the purpose of very fine distribution of the coating agent on the insulating material grains an application from solution / dispersion take place. Additional heating of the coated filler to 2000C is accelerated the coupling reaction and secures by stripping off the hydrolysis product, e.g. isopropyl alcohol, higher temperature resistance.
