Description
Verfahren zur Herstellung eines kombinierten Kunstharzschaumes Kunstharzschaumstoffe erlangen in steigendem Maße technische Bedeutung. Hinsichtlich Preis, Stoßfestigkeit und Isolierfähigkeit stehen solche aus Polystyrol an erster Stelle. Für einige Anwendungszwecke wirken sich dabei jedoch die leichte Brennbarkeit und die geringe Druckfestigkeit nachteilig aus. Schaumstoffe aus Phenolharzen hingegen brennen zwar nicht, weisen auch eine gute Steifigkeit auf, sind aber wegen der geringen Elastizität gegen Stöße sehr empfindlich. Process for the production of a combined synthetic resin foam Synthetic resin foams gain increasing technical importance. In terms of price, shock resistance and insulation properties, those made of polystyrene come first. For some uses However, the easy flammability and the low compressive strength have an effect disadvantageous. Foams made from phenolic resins, on the other hand, do not burn, they say also have good rigidity, but are resistant to impacts because of the low elasticity very sensitive.
Geschäumte Harnstoff- und Melaminharze zeigen ein nicht minder sprödes Verhalten.Foamed urea and melamine resins are no less brittle Behavior.
Durch das nachstehend beschriebene Verfahren erzielt man nun eine Kombination dieser Schaumstoffe, die deren günstige Eigenschaften vereinigt und die bestehenden Nachteile vermeidet. Der dabei gebildete Schaumstoff weist eine vorzügliche Stoß- und Druckfestigkeit auf. Beim Anzünden in der Flamme brennen bestenfalls die an der Oberfläche befindlichen Polystyrolanteile weg, jedoch erlischt der Schaumstoff dann sofort. Auch die Wärmestandfestigkeit erfährt dabei gegenüber den reinen Polystyrolschäumen eine erhebliche Verbesserung. By following the procedure described below, one now achieves a Combination of these foams, which combines their favorable properties and avoids the existing disadvantages. The foam formed has a excellent shock and pressure resistance. When lighting in the flame burn at best the polystyrene parts on the surface are removed, but the foam disappears then immediately. The heat resistance is also experienced compared to pure polystyrene foams a significant improvement.
Zur Verwendung gelangen in erster Linie Phenolharze in noch nicht ausgehärtetem Zustand, in flüssiger oder fester Form, die mit einem der bekannten Treibmittel versetzt sind, z. B. Ammoniumcarbonat, zersetzlichen Azoverbindungen oder auch leicht siedenden Flüssigkeiten. Andere brennwidrige, härtbare Harze wie die Harnstoff- und Melaminharze sind gleichfalls brauchbar. Diese werden mit bereits ganz oder teilweise aufgeschäumten Polystyrolteilchen, die meist in Kugelform vorliegen, vermischt und auf eine der bekannten Weisen zum Aufschäumen gebracht. Die Polystyrolschaumteilchen behalten dabei ihre Form bei oder vergrößern sich sogar noch, während die Zwischenräume von den wärmefesten und flammwidrigen Schaumharzen ausgefüllt werden. Zur Erzielung der gewünschten Eigenschaften soll ein Gewichtsverhältnis der härtbaren Harze zum Polystyrolschaum von 2:1 bis 6:1 eingehalten werden. Phenolic resins have not been used in the first place yet cured state, in liquid or solid form, with any of the known Propellants are added, z. B. ammonium carbonate, decomposable azo compounds or low-boiling liquids. Other non-combustible, curable resins such as the urea and melamine resins are also useful. These will be with already wholly or partially foamed polystyrene particles, which are usually in spherical shape, mixed and made to foam in one of the known ways. The polystyrene foam particles retain their shape or even enlarge while the spaces in between filled with heat-resistant and flame-retardant foam resins. To achieve the desired properties should be a weight ratio of the curable resins to Polystyrene foam of 2: 1 to 6: 1 must be adhered to.
Die härtbaren Harze können in flüssigem oder feinkörnigem Zustand mit den Polystyrolteilchen vermischt und je nach Art kalt oder warm aufgeschäumt werden. So erfolgt beispielsweise die Härtung der flüssigen Harze zweckmäßig in saurem Zustand, je nach gewünschter Geschwindigkeit in Abhängigkeit von der Temperatur. Neutral oder schwach alkalisch eingestellte Harze erfordern meist Temperaturen über 1000 C. Folgende Beispiele dienen der näheren Erläuterung der Arbeitsweise. The curable resins can be in a liquid or fine-grained state mixed with the polystyrene particles and foamed cold or warm depending on the type will. For example, the hardening of the liquid resins expediently takes place in acidic state, depending on the desired speed depending on the temperature. Resins set to be neutral or slightly alkaline usually require temperatures above 1000 C. The following examples serve to explain the working method in more detail.
Beispiel 1 a) 85 Teile Phenolharz-Novolak, 15 Teile Hexamethylentetramin, 10 Teile Polyvinylacetat und 5 Teile Ammoniumcarbonat werden bei etwa 900 C zu einem einheitlichen Fell gewalzt, das anschließend in der Kugelmühle zerkleinert wird. b) Leichtbenzinhaltiges Polystyrol-Perlpolymerisat wird in kochendem Wasser zu Kügelchen von 2 bis 6 mm Durchmesser aufgeschäumt. Example 1 a) 85 parts of phenolic resin novolak, 15 parts of hexamethylenetetramine, 10 parts of polyvinyl acetate and 5 parts Ammonium carbonate become a at about 900 C. uniform skin is rolled, which is then crushed in the ball mill. b) Polystyrene bead polymer containing light gasoline becomes spheres in boiling water foamed from 2 to 6 mm in diameter.
4 Teile des Phenolharzpulvers a) werden mit 1 Teil der Polystyrolschaumkügelchen b) vermischt, wobei zwecks besserer Haftung des Pulvers die Kügelchen schwach angelöst oder mit einem Klebstoff versehen werden können. Nach Füllung in eine Form erhitzt man ohne Druckanwendung 2 Stunden auf 110 bis 1200 C, wobei ein stabiler, unbrennbarer Schaumstoff ohne freie Zwischenräume mit einem spezifischen Gewicht von 0,15 entsteht. 4 parts of the phenolic resin powder a) are mixed with 1 part of the polystyrene foam beads b) mixed, the spheres being slightly loosened for the purpose of better adhesion of the powder or can be provided with an adhesive. Heated after filling in a mold one without the application of pressure for 2 hours at 110 to 1200 C, whereby a stable, non-flammable Foam without free spaces with a specific weight of 0.15 is produced.
Beispiel 2 3 Teile eines flüssigen Phenolharzes, das 2 0/o Petroläther enthält, werden mit Salzsäure kräftig angesäuert, mit 1 Teil der unter Beispiel 1, b) angeführten Polystyrolschaumstoffkügelchen gleichmäßig vermischt und sofort in die auszufüllenden Behälter gebracht. Infolge der dabei entstehenden Reaktionswärme gelangt der Petroläther zum Sieden und schließt unter Aufschäumen die Polystyrolschaumteilchen ein. Example 2 3 parts of a liquid phenolic resin, the 2 0 / o petroleum ether are strongly acidified with hydrochloric acid, with 1 part of the example below 1, b) mentioned polystyrene foam beads are mixed evenly and immediately placed in the container to be filled. As a result of the resulting heat of reaction the petroleum ether comes to the boil and closes the polystyrene foam particles while foaming a.
Beispiel 3 Ein flüssiges Harnstoffharz mit einem Festharzanteil von 60 O/o wird nach Verdickung mit Methylcellulose innig mit 7 0/o Petroläther vermischt und schwach angesäuert. 5 Teile hiervon vermengt man mit 1 Teil der geschäumten Polystyrolkügelchen gemäß Beispiel 1, b). Die damit gefüllten Formen werden kurze Zeit auf 1100 C erhitzt. Die dabei entstehende Schaumharzkombination weist ein spezifisches Gewicht von 0,09 auf. Example 3 A liquid urea resin with a solid resin content of 60 o / o is intimately mixed with 7 o / o petroleum ether after thickening with methyl cellulose and weakly acidified. 5 parts of this are mixed with 1 part of the foamed Polystyrene beads according to Example 1, b). The shapes filled with it will be short Time heated to 1100 C. The resulting foam resin combination has a specific one Weight of 0.09 on.
