Abstract
Description
Verfahren zur Herstellung eines Steines.Method of making a stone.
Die Erfindung betrifft die Herstellung eines Steines, insbesondere die Herstellung eines Pflastersteins. The invention relates to the manufacture of a stone, in particular the production of a paving stone.
Hhnliche Steine sind an sich bekannt und lassen sich in zwei Gruppen unterteilen: 1. In einem Ofen aus Ton gebackener Stein. Ein Nachteil bei dieser Herstellungsart ist, das. zum Brennen viel Energie erforderlich ist. Der Vorteil dieser Steine ist aber, dass sie sich gleichmässig abnutzen und 13 - 18 Gewichtsprozent Wasser aufnehmen können, was zur Vermeidung von Aquaplaning sehr wichtig ist. Similar stones are known per se and can be divided into two groups subdivide: 1. Stone baked in a clay oven. One disadvantage with this one Production method is that. A lot of energy is required for burning. The advantage of these stones, however, is that they wear out evenly and 13 - 18 percent by weight Can absorb water, which is very important to avoid aquaplaning.
2. Beton-Pflastersteine aus grobkörnigem Sand, Kies und Zement.2. Concrete paving stones made from coarse-grained sand, gravel and cement.
Der Vorteil dieser Steine liegt in der Energieeinsparung (sie werden nicht gebrannt), aber sie haben den Nachteil, dass sie sich sehr ungleichmässig abnutzen, insbesondere wenn sich Kiesgravel aus dem Stein herausiöst. The advantage of these stones is energy saving (they will not burned), but they have the disadvantage that they are very uneven wear and tear, especially if gravel gravel detaches itself from the stone.
Ziel der vorliegenden Erfindung ist die Herstellung eines Steins, dessen Aussehen, Verschleissverhalten und Wasseraufnahmeeigenschaften denen eines aus Ton gebrannten Steins entsprechen und dessen Energieverbrauch genauso gering ist wie der von Beton-Pflastersteinen. The aim of the present invention is to produce a stone its appearance, wear behavior and water absorption properties are one of them made of clay baked stone and its energy consumption is just as low is like that of concrete paving stones.
Die Erfindung ist dadurch gekennzeichnet, dass ein Gemisch aus feinkörnigem Sand, Zement und Wasser verwendet wird, dem ein in Wasser dispergiertes Bindemittel aus Kunstharz auf der Basis von Polymeren oder Mischpolymeren, die in einem wasserhaltenden Milieu polymerisert worden sind, zugefügt wird. The invention is characterized in that a mixture of fine-grained Sand, cement and water is used, which is a binder dispersed in water Made of synthetic resin based on polymers or copolymers, which are in a water-retaining Milieu have been polymerized, is added.
Solche in einem wasserhaltenden Milieu polymerisierten Polymere und Mischpolymere werden auch Latizide genannt. Such polymers and polymerized in a water-retaining medium Mixed polymers are also called laticides.
Das als Bindeinittel verwendete Kunstharz ist vorzugsweise ein Vinylmischpolymer und insbesondere ein Vinylacetat-Vinylversatat-Mischpolymer ("versatic acid" ist ein Handel sprodukt von Shell); die zu verwendende Dispersion des Bindemittels in Wasser enthält etwa 50 Gewichtsprozent Wasser. Eine solche Dispersion wird unter dem Namen CO 50 von der Firma Synress, Hoek van Holland, vertrieben. The synthetic resin used as the binder is preferably a vinyl copolymer and in particular a vinyl acetate-vinyl versatate copolymer ("versatic acid") a trading product of Shell); the dispersion of the binder to be used in Water contains about 50 percent water by weight. Such a dispersion is under the name CO 50 from Synress, Hoek van Holland.
Der zu verwendende Sand ist vorzugsweise Quarzitsand, Flusssand oder Silbersand. Der zu verwendende Sand ist ein Gemisch aus scharfem Sand (maschinell gebrochen) und rundem Sand (durch die Natur gebrochen) mit einer gorngrösse von etwa 0,5 mm. The sand to be used is preferably quartzite sand, river sand or Silver sand. The sand to be used is a mixture of sharp sand (machine broken) and round sand (broken by nature) with a grain size of about 0.5mm.
Sand und Zement werden in einem Volumenverhältnis von 3 : 1 bis 7 : 1 verwendet; der Wasser-Zement-Faktor liegt bei 0,28-0,35, wobei die Wassermenge in der Bindemitteldispersion berllcksichtigt wird. Sand and cement are in a volume ratio of 3: 1 to 7 : 1 used; the water-cement factor is 0.28-0.35, with the amount of water is taken into account in the binder dispersion.
Dem Gemisch aus Zement, Sand und Wasser wird eine Bindemitteldispersion von 0,5-15 Gewichtsprozent, vorzugsweise von 2-3 Gewichtsprozent zugefügt. The mixture of cement, sand and water becomes a binder dispersion from 0.5-15 percent by weight, preferably from 2-3 percent by weight.
Auf Wunsch zXird diesem Gemisch ein Farbstoff zugefügt. If desired, a dye can be added to this mixture.
Es sei bemerkt, dass bei dem erfindungsgemässen Verfahren die Verwendung eines Härters nicht erforderlich ist. It should be noted that in the method according to the invention the use a hardener is not required.
Die Erfindung wird jetzt anhand des nachstehenden Beispiels erläutert. The invention will now be explained with reference to the following example.
BeisPiel In einer Mischvorrichtung werden 1600 kg Sand (700 kg scharfer Sand und 900 kg runder Sand mit einer Korngrösse von etwa 0,5 mm), 340 kg Zement, 126 kg Wasser und 19,4 kg Bindemitteldispersion, bestehend aus einem Mischpolymers aus Vinylacetat und Vinylversatat in einem Gewichtsverhältnis von 75:25 una mit etwa 50 Gew.% Feststoffgehalt gemischt. Das Gemisch wird entfernt und zu einer Pressanlage der Firma OMAG, Emden (Bundesrepublik Deutschland) befrdert.EXAMPLE In a mixer, 1600 kg of sand (700 kg of sharp Sand and 900 kg of round sand with a grain size of about 0.5 mm), 340 kg of cement, 126 kg of water and 19.4 kg of binder dispersion, consisting of a mixed polymer from vinyl acetate and vinyl versatate in a weight ratio of 75:25 and with about 50% by weight solids content mixed. The mixture is removed and sent to a press plant of the company OMAG, Emden (Federal Republic of Germany).
In der Pressformmaschine wird das Gemisch über einen Trichter in den Füllwagen der Maschine geleitet. Durch eine pendelartige Vor- und Rückwärtsbewegung des Ftlllwagens füllt sich die Form, wobei zur selben Zeit eine erste Vibration erfolgt, die mittels eines unter der Planke, auf der sich die arretierte Steinform befindet, angeordneten Vibriertisches übertragen wird. Nach dem FUllvorgang senkt sich der Stempel und der Stein wird mittels unter der Plane angeordneter Hauptvibratoren und eines auf dem Stempelsegment angeordneten oberen Vibrators veraichtet.In the compression molding machine, the mixture is poured into the The machine's filling car. With a pendulum-like back and forth movement of the filling truck fills the mold, with a first vibration at the same time takes place by means of an under the plank on which the locked stone shape is located located, arranged vibrating table is transmitted. After the filling process lowers The stamp and the stone are moved by means of main vibrators arranged under the tarpaulin and an upper vibrator arranged on the punch segment.
