Abstract

Gypsum compsn. contains =20%, specifically 3-7%, hard-foam powder as is obtd. is the processing of polyurethane-polyisocyanurate, polycarbodiimide or similar plastics blocks. Specific wt. of the compsn., is smaller than that of the pure gypsum, and provides a useful application for otherwise unserviceable plastics waste. The prod. has good heat-insulating characteristics.

Description

GipsmassenPlaster of paris

Die Erfindung betrifft Gipsmassen, deren Verwendung bei Putzen, Gipskartonplatten, Füll- und Modelliermassen, Abdichtungen und ein Verfahren zur Herstellung dieser Massen.The invention relates to gypsum masses, the use of which in plasters, plasterboard, Filling and modeling compounds, seals and a method for producing them Crowds.

Der Zusatz von bestimmt Kunststoffen zu Gips und Beton ist bekannt. Die Zusätze sollen in erster Linie die Konsistenz und die Verarbeitungszeit beeinflussen oder das spezifische Gewicht der Gipsmasse bzw. des Betons verkleinern. Bedingt durch Energieknappheit und Gesetzgebung wird die Wärmeleitfähigkeit solcher Massen, zunehmend wichtiger. Aufgabe der Erfindung sind Gipsmassen mit kleinerer Wärmeleitfähigkeit.The addition of certain plastics to plaster of paris and concrete is known. The additives are primarily intended to influence the consistency and processing time or reduce the specific weight of the gypsum mass or the concrete. Conditional due to energy shortages and legislation, the thermal conductivity of such masses increasingly important. The object of the invention is plaster of paris with lower thermal conductivity.

Diese Aufgabe wird durch Gipsmassen gelöst, die neben Gips bis zu 20 % Hartschaumstaub enthalten. Dieser Hautschaumstaub fällt besonders bei der Bearbeitung von Polyurethan-, Polyisocyanurat- oder Polycarbodiimid- oder ahnlicher Blockware an.This task is achieved by plaster of paris, which in addition to plaster up to Contains 20% hard foam dust. This skin foam dust falls especially during processing of polyurethane, polyisocyanurate or polycarbodiimide or similar block goods at.

Vorteilhaft an den erfindungsgemäßen Gipsmassen ist die Herabsetzung der Wärmeleitfähigkeit. Bei einem Gips, der 5 % Polyurethanhartschaumstaub enthält, wird die Wärmeleitfähigkeit von 0,24 W/ m auf 0,17 W/ m, also um ca.The advantage of the gypsum masses according to the invention is the reduction the thermal conductivity. In the case of plaster of paris containing 5% polyurethane hard foam dust, the thermal conductivity increases from 0.24 W / m to 0.17 W / m, i.e. by approx.

30 % herabgesetzt.30% discounted.

Es ist möglich, bis zu 20 % Hartschaumstaub beizumischen.It is possible to add up to 20% hard foam dust.

Der Hartschaumstaub muß nicht chemisch einheitlich sein.The hard foam dust does not have to be chemically uniform.

Besonders vorteilhaft sind Gipsmassen die 3 bis 7 % Hartschaumstaub enthalten. Durch die Zugabe von Hartschaumstaub werden die Verarbeitungseigenschaften der Gipsmassen wenig beeinflußt. Mit etwas längeren Topfzeiten kann gerechnet werden.Gypsum compounds containing 3 to 7% hard foam dust are particularly advantageous contain. The processing properties are enhanced by the addition of hard foam dust the plaster of paris has little influence. Somewhat longer pot lives can be expected.

Da der Hartschaumstaub bei der Bearbeitung von Schaumplatten als lästiges Nebenprodukt anfällt, ist durch die erfindungsgemäße Nutzung ein weiterer Vorteil erzielbar.Since the hard foam dust is a nuisance when processing foam sheets By-product is obtained is a further advantage due to the use according to the invention achievable.

Zur Herstellung von Putzen, Gipskartonplatten, Füll- und Modelliermassen oder Abdichtungen wird der Hartschaumstaub der bereits angerührten Gipsmasse zugesetzt. Die Verarbeitungseigenschaften werden nicht negativ beeinflußt. Es ist jedoch in vielen Fällen sinnvoll, wenn bereits der Gipshersteller dem Gips Hartschaumstaub beimischt.For the production of plaster, plasterboard, filling and modeling compounds or seals, the hard foam dust is added to the already mixed plaster of paris. The processing properties are not adversely affected. However, it is in in many cases it makes sense if the plaster of paris manufacturer already gives the plaster of paris hard foam dust admixed.

Durch die Zugabe von Hartschaumstaub nimmt die Festigkeit des Putzes etwas ab. Im Bedarfsfall kann eine obere Schicht aus normalem Gips aufgebracht werden. Wegen der geringeren Dichte lassen sich größere Putzdicken erzielen.The strength of the plaster decreases by adding hard foam dust something off. If necessary, a top layer of normal plaster can be applied. Because of the lower density, greater plaster thicknesses can be achieved.

Eine Gipskartonplatte ist in der Zeichnung dargestellt und im folgenden beispielhaft näher beschrieben.A plasterboard is shown in the drawing and below described in more detail by way of example.

Der Kern 1 der Platte besteht aus einer Gipsmischung, der 5 % Polyurethanhartschaumstaub zugesetzt ist. Pappkarton bildet wie üblich die Oberfläche 2 der Platte.The core 1 of the plate consists of a plaster mixture containing 5% polyurethane hard foam dust is added. As usual, cardboard forms the surface 2 of the plate.
