Abstract
Description
Die Erfindung betrifft eine Auskleidung von Schornsteinen mit einem Kunststoffrohr.The invention relates to a lining of chimneys a plastic tube.
Bei der Verbrennung von üblichen schwefelhaltigen Brenn materialien in modernen Feuerungsanlagen entstehen stets mehr oder weniger große Mengen hochkonzentrierter Schwefelsäure, die sowohl in gemauerten Haus- oder Fabrikschornsteinen als auch in solchen mit Edelstahlauskleidung zu Korrosion und damit lang fristig zur Schädigung des Schornsteins führt. Es besteht daher ein Bedarf nach Sanierung alter, bereits geschädigter Schorn steine sowie nach korrosionsfester Auskleidung neuer Schorn steine.When burning conventional sulfur-containing fuel materials in modern combustion plants are becoming more and more common or less large amounts of highly concentrated sulfuric acid, the both in brick house or factory chimneys and in those with stainless steel lining to corrosion and therefore long leads to damage to the chimney. It therefore exists a need for the renovation of old, already damaged chimneys stones and new chimney after corrosion-resistant lining stones.
In EP-A 650 019 ist die Auskleidung von Schornsteinen mit Rohren aus glasfaserverstärkten ausgehärteten Vinylesterharzen (VE-Harze) oder Cyclohexen- bzw. Cyclopentengruppen enthaltenden Polyesterharzen (HT-Harze) beschrieben. Es hat sich gezeigt, daß ausgehärtete VE-Harze eine für extreme Temperaturbelastungen nicht ausreichende Temperaturbeständigkeit haben, und daß die temperaturbeständigeren HT-Harze die notwendige Chemikalien beständigkeit erst dann erlangen, wenn sie längere Zeit bei Rauchgastemperaturen von mehr als 160°C nachgehärtet worden sind. Nachhärtezeiten von 24 h oder länger sind aber in der Praxis nicht tragbar.EP-A 650 019 describes the lining of chimneys with pipes made of glass fiber reinforced hardened vinyl ester resins (VE resins) or cyclohexene or cyclopentene-containing groups Polyester resins (HT resins) described. It has been shown that hardened VE resins for extreme temperature loads do not have sufficient temperature resistance, and that the temperature-resistant HT resins the necessary chemicals gain stability only if they have been with for a long time Flue gas temperatures of more than 160 ° C have been post-cured. Post-curing times of 24 hours or longer are in practice not portable.
Der Erfindung lag also die Aufgabe zugrunde, eine Auskleidung für Schornsteine zu entwickeln, die sowohl eine hohe Temperatur beständigkeit als auch eine ausreichende Chemikalienbeständigkeit ohne lange Nachhärtezeiten aufweisen.The invention was therefore based on the object of a lining Chimneys develop both high temperature resistance as well as sufficient chemical resistance without long post-curing times.
Gegenstand der Erfindung ist demzufolge eine Auskleidung von Schornsteinen mit einem Kunststoffrohr, das aus einer Innenlage aus glasfaserverstärktem, gehärtetem Vinylesterharz und einer Außenlage aus glasfaserverstärktem, gehärtetem Cyclohexen- oder Cyclopentengruppen enthaltendem Polyesterharz besteht.The invention accordingly relates to a lining of Chimneys with a plastic pipe that comes from an inner layer made of glass fiber reinforced, hardened vinyl ester resin and one Outer layer made of glass fiber reinforced, hardened cyclohexene or Polyester resin containing cyclopentene groups.
Die Auskleidung kann sowohl bei sanierungsbedürftigen Alt- Schornsteinen als auch bei neu errichteten Schornsteinen vorge nommen werden, und zwar bei gemauerten Haus- und Fabrik-Kaminen ebenso wie bei solchen mit Edelstahleinsätzen. The lining can be used for old Chimneys as well as newly constructed chimneys be taken, namely at brick house and factory chimneys just like those with stainless steel inserts.
Zur Auskleidung wird ein harzgetränkter, zweischichtiger Glas faserschlauch wie ein umgestülpter Strumpf in den Schornstein eingeführt und dort aufgeweitet, schließlich wird das Harz gehär tet. Der Schlauch kann auch durch die obere Öffnung des Schorn steins in den Kamin eingehängt werden, dort aufgeweitet und dann gehärtet werden.A resin-soaked, two-layer glass is used for the lining fiber hose like an inverted stocking in the chimney introduced and expanded there, finally the resin is hardened tet. The hose can also go through the top opening of the chimney stones are hung in the fireplace, expanded there and then be hardened.
Ausgangsmaterialien für die erfindungsgemäße Auskleidung sind einerseits ungesättigte Polyesterharze mit Cyclopenten- oder Cyclohexengruppen (HT-Harze) und andererseits Vinylesterharze (VE-Harze).Starting materials for the lining according to the invention are on the one hand unsaturated polyester resins with cyclopentene or Cyclohexene groups (HT resins) and on the other hand vinyl ester resins (VE resins).
Es handelt sich hier um ungesättigte Polyester aus ethylenisch ungesättigten Dicarbonsäuren und Diolen. Als ethylenisch unge sättigte Dicarbonsäuren oder deren Anhydride kommen insbesondere Maleinsäure, Fumarsäure, Itaconsäure und Tetrahydrophthalsäure sowie deren Anhydride in Frage, wobei Maleinsäureanhydrid bevor zugt ist. Daneben können andere Carbonsäuren oder Anhydride, wie Adipinsäure, o-Phthalsäureanhydrid, Trimellithsäure oder Py romellithsäure, mitverwendet werden. Geeignete Diole sind z. B. Propylenglykol-1,2, Ethylenglykol, Diethylenglykol, Butan diol-1,3, Butandiol-1,4, Neopentylglykol sowie hydriertes Bisp henol A. Daneben können Polyole, wie Trimethylolpropan, Glyzerin und Pentaerythrit mitverwendet werden.These are unsaturated polyesters from ethylenic unsaturated dicarboxylic acids and diols. As ethylenically unsure saturated dicarboxylic acids or their anhydrides come in particular Maleic acid, fumaric acid, itaconic acid and tetrahydrophthalic acid and their anhydrides in question, with maleic anhydride before is moving. In addition, other carboxylic acids or anhydrides such as Adipic acid, o-phthalic anhydride, trimellitic acid or Py romellitic acid can also be used. Suitable diols are e.g. B. 1,2-propylene glycol, ethylene glycol, diethylene glycol, butane diol-1,3, butanediol-1,4, neopentyl glycol and hydrogenated bisp henol A. In addition, polyols such as trimethylolpropane, glycerin and pentaerythritol can also be used.
Zum Einbau der Cyclopenten- bzw. Cyclohexen-Gruppierungen in die ungesättigten Polyester werden diese mit Dicyclopentadien bzw. dessen Derivaten oder Substitutionsprodukten modifiziert, vor zugsweise mit Dicyclopentadien oder Endomethylentetrahydrophthal säure. Diese Umsetzungen sind bekannt. Wenn man von Diestern mit hoher Säurezahl oder freier Maleinsäure ausgeht und bei Tempera turen zwischen 120 und 140°C arbeitet, erhält man im wesentlichen eine Addition des Dicyclopentadiens an endständige Carboxyl- bzw. Hydroxylgruppen, wobei sich endständige Dicyclopentenylester bzw. Dicyclopentenylethergruppen bilden. Setzt man Polyester mit niedriger Säurezahl ein und arbeitet bei höheren Temperaturen, vorzugsweise oberhalb von 170°C, so spaltet sich das Dicyclopenta dien in zwei Moleküle Cyclopentadien, welches sich an Ethylen dicarbonsäureester-Strukturen des Polyesters addiert und Endo methylentetrahydrophthalsäureester-Strukturen bildet. Diese Strukturen lassen sich auch durch den Einsatz von Endomethylen tetrahydrophthalsäure oder deren Anhydrid erzeugen. For the incorporation of the cyclopentene or cyclohexene groups into the unsaturated polyesters with dicyclopentadiene or modified its derivatives or substitution products preferably with dicyclopentadiene or endomethylene tetrahydrophthal acid. These implementations are known. If you come up with diesters high acid number or free maleic acid and at tempera tures between 120 and 140 ° C works essentially an addition of dicyclopentadiene to terminal carboxyl or Hydroxyl groups, with terminal dicyclopentenyl esters or dicyclopentenyl ether groups. If you add polyester low acid number and works at higher temperatures, preferably above 170 ° C, the dicyclopenta splits serve in two molecules of cyclopentadiene, which is attached to ethylene dicarboxylic acid ester structures of the polyester added and endo forms methylene tetrahydrophthalic acid ester structures. This Structures can also be created using endomethylene Generate tetrahydrophthalic acid or its anhydride.
Bei einer bevorzugten Ausführungsform werden die modifizierten ungesättigten Polyester einem zusätzlichen Endgruppenverschluß mit N-Hydroxyalkyltetrahydrophthalimid bzw. N-Hydroxyalkylen dimethylentetrahydrophthalimid unterworfen. Solche Umsetzungen sind z. B. in der deutschen Patentanmeldung P 32 30 924 beschrie ben.In a preferred embodiment, the modified unsaturated polyester an additional end group closure with N-hydroxyalkyl tetrahydrophthalimide or N-hydroxyalkylene subjected to dimethylene tetrahydrophthalimide. Such implementations are z. B. in the German patent application P 32 30 924 ben.
Kennzeichnend für diese Klasse von Harzen ist die GruppeThe group is characteristic of this class of resins
mit R = H oder CH₃.with R = H or CH₃.
Unter VE-Harzen, die auch Epoxidacrylate genannt werden, versteht man Umsetzungsprodukte von Polyepoxiden mit ungesättigten Mono carbonsäuren, vorzugsweise mit Methacrylsäure. Diese Harze werden beispielsweise in GB-A 1 006 587 und in den US-PS 3 066 112 und 3 179 623 beschrieben. VE-Harze auf Basis von Bisphenol A zeich nen sich durch hohe Zähigkeit und gute Chemikalienbeständigkeit bei begrenzter Wärmeformbeständigkeit aus. Die bevorzugten Vinyl esterharze aus Epoxy-Novolakharzen und (Meth-)Acrylsäure, wie sie beispielsweise in der US-PS 3 256 226 beschrieben werden, weisen dagegen höhere Wärmeformbeständigkeiten, aber geringere Zähig keiten auf.VE resins, which are also called epoxy acrylates, are understood reaction products of polyepoxides with unsaturated mono carboxylic acids, preferably with methacrylic acid. These resins will be for example in GB-A 1 006 587 and in U.S. Patents 3,066,112 and 3 179 623. Draw VE resins based on bisphenol A are characterized by high toughness and good chemical resistance with limited heat resistance. The preferred vinyl ester resins from epoxy novolak resins and (meth) acrylic acid, as they described, for example, in US Pat. No. 3,256,226 in contrast, higher heat resistance, but lower toughness come on.
Neben üblichen VE-Harzen sind auch carboxylmodifizierte Varianten vorteilhaft einsetzbar. Sie lassen sich leicht durch Umsetzung der Hydroxylgruppen von VE-Harzen mit Dicarbonsäureanhydriden, wie beispielsweise Maleinsäureanhydrid, o-Phthalsäureanhydrid oder Tetrahydrophthalsäureanhydrid, herstellen, wobei unter Ring öffnung Halbesterstrukturen entstehen. Solche VE-Harze sind dann bevorzugt, wenn sie nach der Tränkung eingedickt werden sollen.In addition to the usual VE resins, there are also carboxyl-modified variants can be used advantageously. They can be easily implemented the hydroxyl groups of VE resins with dicarboxylic acid anhydrides, such as maleic anhydride, o-phthalic anhydride or tetrahydrophthalic anhydride, produce, under ring opening half-ester structures arise. Such VE resins are then preferred if they are to be thickened after impregnation.
Die HT- bzw. VE-Harzen werden in einer bevorzugten Ausführungs form in Vinylmonomeren gelöst, wobei üblicherweise 20 bis 100 Gew.-Teile Monomer auf 100 Gew.-Teile Polyester verwendet werden. Geeignete Vinylmonomere sind z. B. Styrol, Methylstyrol, Chlorstyrol oder Methylmethacrylat. Darüber hinaus können bevor zugt zusätzlich noch Monomere verwendet werden, die erst bei hö heren Temperaturen polymerisieren, z. B. Diallylphthalat, trans- Endomethylentetrahydrophthalsäurediethylester oder Endomethylentetrahydrophthalsäuredihydroxyethylester.The HT or VE resins are in a preferred embodiment Form dissolved in vinyl monomers, usually 20 to 100 parts by weight of monomer are used per 100 parts by weight of polyester will. Suitable vinyl monomers are e.g. B. styrene, methyl styrene, Chlorostyrene or methyl methacrylate. In addition, before in addition, monomers are used, which are only at high polymerize higher temperatures, e.g. B. diallyl phthalate, trans Endomethylene tetrahydrophthalic acid diethyl ester or Endomethylene tetrahydrophthalic acid dihydroxyethyl ester.
Die HT- und VE-Harze können die üblichen Zusatzstoffe, wie Füll stoffe, Inhibitoren, Stabilisatoren, Farbstoffe, Pigmente, Ein dickmittel und Beschleuniger bzw. Promotoren enthalten.The HT and VE resins can contain the usual additives, such as fillers substances, inhibitors, stabilizers, dyes, pigments, a contain thickeners and accelerators or promoters.
Bei der Herstellung der Auskleidung werden Glasfasermatten bzw. Glasfasergewebe, die eine Dicke von 1 bis 5 mm aufweisen, mit dem jeweiligen Harz getränkt, das anschließend vorzugsweise einge dickt wird. Als Eindickmittel dienen übliche Magnesium- oder Calciumoxide bzw. -hydroxide. Die Eindickung wird durch leichtes Erwärmen bewirkt. Je eine mit VE-Harz getränkte und mit HT-Harz getränkte Lage werden zusammengeführt und zu einem Schlauch ge formt, dessen Durchmesser und Länge etwa den Abmessungen des Schornsteins entspricht. Das kann beispielsweise dadurch ge schehen, daß man die beiden harzgetränkten Lagen übereinander schraubenförmig auf einen Kern wickelt und anschließend den ent standenen Schlauch von dem Kern abzieht.When manufacturing the lining, glass fiber mats or Glass fiber fabric, which have a thickness of 1 to 5 mm, with the each resin soaked, which then preferably turned on is thick. Common magnesium or Calcium oxides or hydroxides. The thickening is made easy Heating causes. One each soaked with VE resin and with HT resin soaked layer are brought together and ge to a hose forms, whose diameter and length roughly correspond to the dimensions of the Corresponds to chimney. This can be done, for example see that you put the two resin-soaked layers on top of each other helically wrapped on a core and then ent pulls the standing tube from the core.
Der Schlauch wird innen und außen mit einer temperaturbeständigen Folie, z. B. aus Polyamid, Polyurethan oder Polyvinylalkohol um hüllt. Dies kann entweder erst aus dieser Stelle geschehen; die Schläuche konnten aber auch schon beim Tränken der Glasfaser matten bzw. beim Zusammenführen auf Folien abgelegt worden sein (siehe DE-A 43 26 503). Der Schlauch wird dann an seinem unteren Ende verschlossen, in dem Schornstein eingeführt und zu einem Rohr aufgeweitet. Bei neuen, engen Schornsteinen kann das Rohr an der Innenwand des Schornsteins anliegen; bei älteren, sanierungs bedürftigten Schornsteinen mit zu weitem Innendurchmesser kann das Rohr frei durchhängen, wobei durch ein außen angelegtes Glas fasergewebe verhindert werden kann, daß der Schlauch zu stark aufgeweitet wird. Das Aufweiten kann des Schlauches entweder dadurch erfolgen, daß man ihn mit Wasser füllt, oder daß man ihn auch an seinem oberen Ende verschließt und dann mit Luft oder Wasserdampf aufbläst. Schließlich kann man auch einen tropfen förmigen Körper, dessen Außendurchmesser dem Innendurchmesser des Schornsteins abzüglich der Dicke des Schlauchs entspricht, durch den Schlauch drückt und diesen dadurch aufweitet. In diesem Fall muß simultan die Härtung durchgeführt werden, da sonst der Schlauch nach dem Durchgang des tropfenförmigen Körpers wieder zusammenfallen würde.The hose is inside and outside with a temperature resistant Foil, e.g. B. from polyamide, polyurethane or polyvinyl alcohol envelops. This can only happen from this point; the Hoses were also able to soak the glass fiber matt or have been placed on foils when merging (see DE-A 43 26 503). The hose will then be at its bottom Locked end, inserted in the chimney and one Tube widened. With new, narrow chimneys, the pipe can come on lie against the inside wall of the chimney; older, renovation in need of chimneys with too large an inner diameter hang the pipe freely, passing through an outside glass Fiber fabric can prevent the hose from becoming too strong is expanded. The tube can be expanded either by filling it with water or by filling it with water also closes at its upper end and then with air or Inflates water vapor. After all, you can also drop one shaped body, the outer diameter of the inner diameter of the Corresponds to the chimney minus the thickness of the hose presses the hose and thereby expands it. In this case the hardening must be carried out simultaneously, otherwise the Hose again after passage of the teardrop-shaped body would collapse.
Die Härtung kann entweder thermisch oder vorzugsweise durch ener giereiche Strahlung erfolgen. Im ersten Fall enthält das Harz Peroxid-Katalysatoren, z. B. ein Kalthärtungs-System Ketonper oxid/Kobaltbeschleuniger oder Acylperoxid/Aminbeschleuniger, zu sammen mit Radikalbildnern, die bei höherer Temperatur zerfallen, wie tert.-Butylperbenzoat, Dicumylperoxid oder Ditertiärbutylpe roxid. Die Härtung erfolgt bei Temperaturen zwischen 80 und 120°C durch heiße Luft, Wasserdampf oder dadurch, das man das zum Auf weiten in den Schlauch eingefüllte Wasser erhitzt. Im Fall der bevorzugten Lichthärtung enthält das Harz einen Photoinitiator, z. B. einen Benzoinether, ein Benzilketal oder ein Acyl phosphinoxid, vorzugsweise wieder zusammen mit einem bei hohen Temperaturen zerfallenden Radikalbildner. Die Härtung erfolgt mittels UV-Strahlung, wobei geeignete Lampen in den Schornstein abgelassen werden oder in den tropfenförmigen Körper eingebaut bzw. angebaut sein können.The hardening can either be thermal or preferably by ener greedy radiation occur. In the first case, the resin contains Peroxide catalysts, e.g. B. a Ketonper cold curing system oxide / cobalt accelerator or acyl peroxide / amine accelerator, too together with radical formers, which decay at higher temperatures, such as tert-butyl perbenzoate, dicumyl peroxide or ditertiary butylpe roxid. Curing takes place at temperatures between 80 and 120 ° C through hot air, water vapor or by opening it wide water heated in the hose. In the case of preferred light curing, the resin contains a photoinitiator, e.g. B. a benzoin ether, a benzil ketal or an acyl phosphine oxide, preferably again together with one at high Free radical decomposing temperatures. The hardening takes place by means of UV radiation, using suitable lamps in the chimney be drained or built into the teardrop-shaped body or can be attached.
Nach erfolgter Härtung ist das Rohr formstabil und chemikalien beständig. Es ist auch zunächst bei Temperaturen bis zu etwa 160°C hitzebeständig. Sollte die Rauchgastemperatur im Extremfall 160°C übersteigen, dann kann zwar das gehärtete VE-Harz der Innenlage etwas erweichen, gleichzeitig setzt aber die Nachhärtung des HT-Harzes der Außenlage ein, wodurch dessen Hitzebeständigkeit auf Temperaturen oberhalb von 200°C ansteigt. Bei der Nachhärtung tritt wahrscheinlich eine zusätzliche Vernetzung der Polymer ketten durch Polymerisation der in den Dicyclopentadiengruppen noch enthaltenen Doppelbindungen ein.After curing, the tube is dimensionally stable and chemical resistant. It is also initially at temperatures up to about 160 ° C heat resistant. In extreme cases, the flue gas temperature should be 160 ° C exceed, then the hardened VE resin of the inner layer soften somewhat, but at the same time the post-hardening of the HT resin of the outer layer, which makes its heat resistance to temperatures above 200 ° C. During post-curing additional crosslinking of the polymer likely occurs chains by polymerization of those in the dicyclopentadiene groups double bonds still contained.
