Description
-pulvern auf die Harzschicht aufgetragen wird, solange sich-powders is applied to the resin layer as long as it is
diese noch in weichem Zustand befindet. Nach dem vollständigen Aushärten der Schicht nach einigen Stunden wird eine weitere Lackschicht auf die Schleifmittel aufgetragen und unmittelbar danach wird eine weitere Schicht von Schleifmittelkörnern bzw. -pulvern aufgetragen. Dieser Vorgang wird mehrere Male wiederholt, bis ein Ueberzug von gewünschter Dicke je nach den Anforderungen an die Oberfläche hinsichtlich Abrieb-, Erosion-, Korrosionsfestigkeit, Verkehrssicherheit usw., erzielt worden ist.this is still in a soft state. After complete hardening The layer after a few hours is another layer of lacquer on the abrasive applied and immediately after that another layer of abrasive grains is applied or powder applied. This process is repeated several times until one Coating of the desired thickness depending on the requirements for the surface Abrasion, erosion, corrosion resistance, traffic safety, etc., have been achieved is.
Wirtschaftlichkeit und Perfektion in der Beschichtung von Industriefussböden sind einige der hervorstechenden Eigenschaften des erfindungsgemässen Verfahrens. Ein weiterer Vorteil ist der geringe Zeitaufwand für die Wartung und Instandhaltung der Bodenbeschichtungen.Economy and perfection in the coating of industrial floors are some of the salient features of the process according to the invention. Another advantage is the short time required for maintenance and servicing of floor coatings.
Das erfindungsgemässe Verfahren beruht auf dem Prinzip der Kombination verschiedener Schichten aus ursprünglich flüssigen Harzmischungen mit Feststoffen aus Schleifmittelkörnern aus Aluminiumoxyd und Siliciumcarbid sowie Pulvern aus Schleifmitteln und Hartfüllstoffen, wie natürlichen Schleifmitteln. Für denselben Zweck können alle Arten von Schleifmittelabfällen verwendet werden, wie sie beispielsweise in Fabriken zur Herstellung von Schleifscheiben anfallen. Bevorzugt werden Körner bzw. Pulver von Substanzen mit einer Härte auf der Mohs'schen Skala von mehr als 8,5, insbesondere mit einer Härte zwischen 8,5 und 9,5.The method according to the invention is based on the principle of combination different layers of originally liquid resin mixtures with solids from abrasive grains made of aluminum oxide and silicon carbide as well as powders Abrasives and hard fillers such as natural abrasives. For the same Purpose can be used all kinds of abrasive waste, such as incurred in factories for the production of grinding wheels. Grains are preferred or powder of substances with a hardness on the Mohs scale of more than 8.5, in particular with a hardness between 8.5 and 9.5.
Die erste Schicht aus Kunstharz (im folgenden auch als "Lack" bezeichnet) wird auf die zu beschichtende Oberfläche aufgetragen, nachdem dieselbe durch Bürsten oder Sprühen (Kaltsprühen) gereinigt worden ist. Je nach der Korngrösse der Schleifmittelkörner wird die Dicke der Schicht durch die Viskosität des Lackes bestimmt. Nach dem Aufbringen der Schleifmittelkörner ragen einige dieser Körner aus der ersten Lackschicht heraus. Nach dem vollständigen Härten der Lackschicht werden die überschüssigen Körner durch Pressluft oder Bürsten entfernt, und dann wird eine weitere Lackschicht gefolgt von dem Aufbringen weiterer Schleifmittelkörner aufgebracht. Nach dem vollständigen Härten werden die überschüssigen Körner wiederum entfernt und dann wird eine weitere Lackschicht aufgebracht. Das Verfahren wird schliesslich durch das Aufbringen einer letzten Lackschicht zum Schutz der Schicht von Schleifmittelkörnern beendet. Lackschichten und Schleifmittelkornschichten sind ohne Unterbrechung der Kontinuität fest miteinander verbunden, wodurch eine Gesamtschicht mit vorbestimmter Dicke entsteht. Ein weiterer wichtiger Punkt ist, dass ein bestimmtes Korn zur Hälfte von der unteren Lackschicht und zur Hälfte durch die darüber befindliche Lackschicht gehalten wird. Ausserdem kann die zweite und/oder die dritte Schicht von Körnern eine feinere Korngrösse aufweisen, so dass sie die Zwischenräume zwischen den zuerst aufgebrachten Körnern besser ausfüllt.The first layer of synthetic resin (hereinafter also referred to as "lacquer") is applied to the surface to be coated after the same by brushing or spray (cold spray) has been cleaned. Depending on the grain size of the abrasive grains the thickness of the layer is determined by the viscosity of the paint. After applying of the abrasive grains, some of these grains protrude from the first Paint layer out. After the paint layer has completely hardened, the excess Grains are removed by compressed air or brushing, and then another layer of varnish is applied followed by the application of additional abrasive grits. After the complete Hardening will remove the excess grains in turn and then another Paint layer applied. The process is finally carried out by applying a Finished last coat of varnish to protect the layer of abrasive grains. Paint layers and abrasive grain layers are fixed to one another without breaking the continuity connected, whereby an overall layer with a predetermined thickness is formed. Another important point is that a certain grain is halfway from the lower layer of varnish and half is held by the lacquer layer above. Besides that the second and / or the third layer of grains can have a finer grain size so that they fill the gaps between the first applied grains fills out better.
Es ist festzustellen, dass dieses Auftragungsverfahren zur Beschichtung der Oberflächen gegenüber bekannten Verfahren den Vorteil mit sich bringt, dass beim Aufbringen der zweiten Schicht aus Lack und Körnern die erste Schicht bereits ausgehärtet ist.It should be noted that this application method for coating the surface has the advantage over known methods that when the second layer of lacquer and grains is applied, the first layer is already applied is cured.
Ein weiterer wichtiger Punkt ist, dass die nach dem erfindungsgemässen Verfahren erhaltene Schicht (von etwa 3 mm Dicke) keine Wanderung und kein Absetzen der Körner am Boden der Schicht zeigt. Sämtliche Lackschichten und Körner sind sehr gut miteinander verschweisst. Die Endschicht weist eine hohe mechanische Widerstandsfähigkeit auf, und es ist die Garantie gegeben, dass keine kontinuierliche Porosität auftritt.Another important point is that according to the invention Method obtained layer (about 3 mm thick) no migration and no settling the grain shows at the bottom of the layer. All the layers of varnish and grains are very well welded together. The final layer has a high mechanical resistance and there is a guarantee that continuous porosity will not occur.
Diese Eigenschaften sind besonders wichtig für Fussböden in Gewerbebetrieben und Fabriken, in denen die Fussböden starker Abrasion und der Einwirkung verschiedener Arten von aggressiven Chemikalien unterliegen. Ausserdem müssen industriell benutzte Fussböden widerstandsfähig gegen die Korrosion durch Reinigungsmittel sein, die täglich nach Arbeitsschluss oder am Wochenende angewendet werden. Eine ganze Anzahl industrieller Rückstände muss mit Lösungsmitteln entfernt werden, wodurch das Fussbodenmaterial angegriffen wird, wenn die Schutzschicht Poren aufweist oder nicht beständig gegenüber Chemikalien ist.These properties are particularly important for floors in commercial establishments and factories in which the floors are subject to severe abrasion and exposure to various Kinds of harsh chemicals are subject to. They must also be used industrially Floors must be resistant to corrosion from cleaning agents that can be used daily after work or on weekends. Quite a number industrial residues must be removed with solvents, thereby removing the flooring material is attacked if the protective layer has pores or is not resistant to it Chemicals is.
Das erfindungsgemässe Verfahren und Mittel erfüllt beide genannten Bedingungen, nämlich die der hohen chemischen Widerstandsfähigkeit und die des Fehlens jeder Porosität. Da die verschiedenen Lackschichten nacheinander aufgebracht worden sind, liegen durch Lackschichten miteinander verbundene Schichten von Körnern vor; es fehlt die Sedimentation der Körner, und es erfolgt eine feste Verbindung mit praktisch allen Arten von Fussbodenmaterialien; die Aufbringung ist ausserordentlich schnell und einfach.The method and means according to the invention fulfill both of the above Conditions, namely those of high chemical resistance and those of absence any porosity. Because the different layers of paint have been applied one after the other are, there are layers of grains connected to one another by layers of lacquer; there is no sedimentation of the grains, and there is a firm connection with practically all types of flooring materials; the application is extraordinary fast and easy.
