Description
Die vorliegende Erfindung betrifft nichtbrennbare Polyol- und/oder Polyethervormischungen zur Herstellung von Schaumstoffen, insbesondere von Polyurethanschaumprodukten.The present invention relates to non-combustible Polyol and / or polyether premixes for the production of Foams, especially of polyurethane foam products.
Polyurethanschäume werden durch Umsetzung von Isocyana ten mit einem Polyol oder einer Polyolmischung in Gegenwart von Treibmittel, vorzugsweise Hydrofluoralkanen hergestellt.Polyurethane foams are made by implementing Isocyanana ten with a polyol or a polyol mixture in the presence of blowing agents, preferably hydrofluoroalkanes.
Die Verwendung von 1,1,1,3,3-Pentafluorbutan (R365mfc) als Treibmittel zur Herstellung von Polyurethanschaumstoffen ist bekannt. Da 1,1,1,3,3-Pentafluorbutan einen Flammpunkt unter -27°C besitzt, gilt es als leicht entzündliche Flüs sigkeit und seiner Verwendung als Treibmittel sind Grenzen gesetzt. Üblicherweise wird daher 1,1,1,3,3-Pentafluorbutan im Gemisch mit anderen Fluorkohlenwasserstoffen eingesetzt.The use of 1,1,1,3,3-pentafluorobutane (R365mfc) as a blowing agent for the production of polyurethane foams is known. Since 1,1,1,3,3-pentafluorobutane has a flash point below -27 ° C, it is considered to be a highly flammable river and its use as a blowing agent are limits set. Therefore, 1,1,1,3,3-pentafluorobutane is usually used used in a mixture with other fluorocarbons.
Es ist ebenfalls bekannt und üblich, zur Schaumherstel lung zunächst aus den verschiedenen Einsatzstoffen sogenannte Vormischungen herzustellen, die dann mit dem Isocyanat zur Reaktion gebracht werden. Zur Herstellung der Vormischung werden Polyole oder Polyether, Treibmittel, Katalysatoren und gegebenenfalls weitere Additive in den benötigten Mengen mit einander vermischt. Die Schäume werden dann durch Inkontakt bringen der Vormischung mit dem Isocyanat bzw. Isocyanaten hergestellt.It is also known and customary to make foam First of all, the so-called Prepare premixes, which are then with the isocyanate Response. To make the premix are polyols or polyethers, blowing agents, catalysts and if necessary, other additives in the required amounts mixed together. The foams are then in contact bring the premix with the isocyanate or isocyanates manufactured.
Die Aufgabe der Erfindung besteht darin, eine nicht brennbare, stabile Vormischung zur Herstellung von Schaumstoffen bereitzustellen, die insbesondere dort Verwendung finden kann, wo keine explosionsgeschützten Anlagen vorhanden sind.The object of the invention is not one flammable, stable premix for the production of foams to provide the particular use there can find where there are no explosion-proof systems are.
Erfindungsgemäß wird eine Mischung, die 1 bis 35 Gew.-% insbesondere 4 bis 30 Gew.-% 1,1,1,3,3-Pentafluorbutan (R365mfc) als Treibmittel, Polyol bzw. Polyether und gegebe nenfalls oberflächenaktive Substanzen, Katalysatoren, Flamm schutzmittel und Wasser enthält, hergestellt.According to the invention, a mixture which is 1 to 35% by weight in particular 4 to 30 wt .-% 1,1,1,3,3-pentafluorobutane (R365mfc) as blowing agent, polyol or polyether and given if necessary, surface-active substances, catalysts, flame contains protective agents and water.
Es wurde gefunden, daß der Flammpunkt der Mischungen mit 1,1,1,3,3-Pentafluorbutan erhöht wird im Vergleich zum Flamm punkt von reinem 1,1,1,3,3-Pentafluorbutan.It was found that the flash point of the mixtures with 1,1,1,3,3-pentafluorobutane is increased compared to the flame point of pure 1,1,1,3,3-pentafluorobutane.
Es wurde weiterhin gefunden, daß bestimmte Abmischungen mit Polyolen oder Polyolsystemen zur Herstellung von Polyure thanschaumprodukten, die 1,1,1,3,3-Pentafluorbutan in Mengen von z. B. 4 Gew.-% (bezogen auf Polyol/Polyolsystem) enthal ten, nicht mehr als entzündliche Mischung gelten.It has also been found that certain blends with polyols or polyol systems for the production of polyures than foam products containing 1,1,1,3,3-pentafluorobutane in quantities from Z. B. 4 wt .-% (based on polyol / polyol system) no longer count as an inflammable mixture.
Zur Herstellung der Polyurethanschäume werden üblicher weise Polyisocyanate beispielsweise mit 2 bis 4 Isocyanat gruppen eingesetzt.To produce the polyurethane foams are more common example polyisocyanates with 2 to 4 isocyanate groups used.
Diese Isocyanate weisen einen aliphatischen Kohlenwas serstoffrest mit bis zu 18 C-Atomen, einen cycloaliphatischen Kohlenwasserstoffrest mit bis zu 15 C-Atomen, einen aromati schen Kohlenwasserstoffrest mit 6 bis 15 C-Atomen oder einen araliphatischen Kohlenwasserstoffrest mit 8 bis 15 C-Atomen auf. Technisch besonders bevorzugte Ausgangskomponenten sind beispielsweise 2,4- und 2,6-Toluylendiisocyanat, Diphenyl methandiisocyanat, Polymethylenpolyphenylisocyanat und deren Mischungen. Es können auch sogenannte modifizierte Polyiso cyanate eingesetzt werden, welche Carbodiimidgruppen, Urethangruppen, Alophanatgruppen, Isocyanoratgruppen, Harn stoffgruppen oder Biuretgruppen enthalten. These isocyanates have an aliphatic carbonate residue of up to 18 carbon atoms, a cycloaliphatic Hydrocarbon residue with up to 15 carbon atoms, an aromatic hydrocarbon residue with 6 to 15 carbon atoms or one araliphatic hydrocarbon radical with 8 to 15 carbon atoms on. Technically particularly preferred starting components are for example 2,4- and 2,6-tolylene diisocyanate, diphenyl methane diisocyanate, polymethylene polyphenyl isocyanate and their Mixtures. So-called modified polyiso can also be used cyanates are used, which carbodiimide groups, Urethane groups, alophanate groups, isocyanorate groups, urine contain groups of substances or biuret groups.
Weitere Ausgangskomponenten sind Verbindungen mit minde stens 2 gegenüber Isocyanaten reaktionsfähigen Wasserstoff atomen. Es handelt sich insbesondere um Verbindungen mit ei nem Molekulargewicht von 400 bis 10.000, welche vorzugsweise 2 bis 8 Hydroxylgruppen aufweisen und außerdem Aminogruppen, Thiolgruppen oder Carboxylgruppen aufweisen können.Other starting components are connections with min at least 2 hydrogen reactive towards isocyanates atoms. In particular, there are connections with egg nem molecular weight from 400 to 10,000, which preferably Have 2 to 8 hydroxyl groups and also amino groups, May have thiol groups or carboxyl groups.
Vorzugsweise werden Polyetherpolyole oder Polyester polyole eingesetzt.Polyether polyols or polyesters are preferred polyols used.

Der Vorteil der erfindungsgemäßen Vormischung besteht darin, daß durch die Verwendung von 1,1,1,3,3-Pentafluorbutan eine nichtbrennbare Vormischung bereitgestellt wird, die außerdem günstige Eigenschaften im Hinblick auf ODP, GWP und Photosmog besitzt. Verglichen mit Polyurethanschaumstoffen, die mit reinen Kohlenwasserstoffen als Treibmittel herge stellt worden sind, zeichnen sich die nach dem erfindungsge mäßen Verfahren hergestellten Schaumstoffe durch eine bessere Wärmeleitzahl aus.The advantage of the premix according to the invention is in that by using 1,1,1,3,3-pentafluorobutane a non-combustible premix is provided which also favorable properties with regard to ODP, GWP and Owns Photosmog. Compared to polyurethane foams, with pure hydrocarbons as blowing agents have been drawn, stand out according to the Invention Foam produced by a better process Thermal conductivity coefficient.
