Description
Doppelsprühdose zur Herstellung von Polyurethan-SohaTimstoffen Double spray can for the production of polyurethane soapy fabrics
Gegenstand der Neuerung ist eine Doppelsprühdose, mit deren Hilfe auf einfache Weise Polyurethan-Schaumstoffe hergestellt werden können.The object of the innovation is a double spray can with the help of which polyurethane foams can be produced in a simple manner.
Die Herstellung von Polyurethan-Schaumstoffen nach dem Handmischverfahren soyirie mit Hilfe von Schäumgeräten ist bekannt. Weiterhin ist die Verwendung von Halogenalkanen mit verschieden gelfcgertenSiedepunkten als Treibmittel für die auX den Eeaktionskomponenten sich bildenden Schaumstoffe bekannt.The production of polyurethane foams by the hand mixing process soyirie with the help of foaming equipment is known. There is also the use of haloalkanes with different boiling points as a propellant for the reaction components formed foams known.
In dem Bestreben, insbesondere.für die handwerkliche Anwendung von Polyurethan-Schaumstoffen eine Technik aufzufinden, die von jedermann ausgeführt werden kann, wurde eine Doppelsprühdöse:" entwickelt, die in Verbindung mit einer vorgeschalteten einfachen Mischvorrichtung die Herstellung von Schaumstoffen gestattet.In the endeavor, especially. For the artisanal Using polyurethane foams to find a technique that anyone can do, a double spray nozzle: "was developed, which in connection with a simple mixing device connected upstream the production of foams is permitted.

Pie neuerungsgemäße "Boppelsprühdose besteht aus einem Druckgefäß 1, in dem sich ein Polyisocyanatgemisch mit einer bestimmten Menge eines bei Raumtemperatur und erhöhtem Druck flüssigen Halogenalkane befindet, und einem Druckgefäß 2, das ein Gemisch eines Polyols mit den zur Verschäumung erforderlichen Hilfsstoffen enthält. Die Funktionalität dieses Gemisches ist in bezug auf die Umsetzung mit dem im Gefäß 1 befindlichen Polyisocyanat so eingestellt, daß ein Gewichtsteil dieses Gemisches mit einem Gewiehtsteil Polyisocyanat zu einer vollständigen Umsetzung gelangem· Wesentlich ist weiter, daß die Viskosität dieses Gemisches sich von der des Polyisocyanate, beide bei Raumtemperatur, nicht nennenswert unterscheidet. AuGh dem Gemisch im Gefäß 2 wird eine bestimmte Menge eines bei Raumtemperatur und erhöhtem Druck flüssigen Halogenalkane zugefügt; die Menge braucht mit der im JSjifJJiWI enthaltenen nicht übereinzustimmen. Es·Pie according to the innovation "Boppelsprühdose consists of a pressure vessel 1 in which there is a polyisocyanate mixture with a certain amount of a haloalkane that is liquid at room temperature and under increased pressure is located, and a pressure vessel 2, which is a mixture of a polyol with the required for foaming Contains excipients. The functionality of this mixture is related to the implementation with the polyisocyanate in vessel 1 adjusted so that one part by weight of this mixture with one part by weight of polyisocyanate to a complete Implementation successful It is also essential that the viscosity of this mixture differs from that of the Polyisocyanates, both at room temperature, do not differ significantly. AuGh the mixture in the vessel 2 a certain amount of a haloalkane which is liquid at room temperature and under increased pressure is added; the amount needs with that contained in the JSjifJJiWI do not match.

Das im Reaktionsgemisch gelöst« Halogenalkan bzw. die Halogenalkane übernehmen dann in an sich bekannter Weise die Funktion des Treibmittels für den aus dem Gemisch sich bildenden Schaumstoff. Aufgrund der Beschaffenheit des Reaktionsgemische und der Natur des Verarbeitungsverfahrens eignet sich dieses Verfahren insbesondere zur Beschichtung von Flächen mit Schaumstoff.Normal pressure is below room temperature, the two reactants into the nozzle where they are mixed together} the mixture then emerges from the nozzle in the form of an aerosol Dissolved in the reaction mixture, the haloalkane or the haloalkanes then take over in a manner known per se Way the function of the blowing agent for the foam formed from the mixture. Because of the nature of the reaction mixture and the nature of the processing method This process is particularly useful for coating surfaces with foam.
