Abstract
Description
Beschichtung von Betonflächen, Betondachsteinen und Betonelementen sowie mineralisch gebundenen Holzwolleleichtbauplatten mit einer farbigen kunststoffhaltigen Zementschlämme Die Erfindung betrifft ein Verfahren zur Beschichtung von Betonflächen, Betondachsteinen und Betonelementen sowie mineralisch gebundenen Holzwollelei ch-tbauplatten zur Gestaltung der Sichtflächen. Coating of concrete surfaces, concrete roof tiles and concrete elements as well as mineral-bound wood wool lightweight boards with a colored plastic-containing Cement slurry The invention relates to a method for coating concrete surfaces, Concrete roof tiles and concrete elements as well as minerally bound wood woolen construction panels for designing the visible surfaces.
Die Oberflächenbehandlung von Betondachsteinen und Betonelementen sowie mineralisch gebundenen Holzwolleleichtbauplatten; die einmal aus architektonischen und zum andren aus Wichtig keitsgründen durchgeführt wird, besteht im Durchfärben, Aufbringen einer farbigen Zementschlämme mit einem entsprechenden Granulat in Kunststoffbeschichtungen oder Anstrichen.The surface treatment of concrete roof tiles and concrete elements as well as mineral-bound wood wool lightweight boards; the once from architectural and, on the other hand, is carried out for reasons of importance, consists of dyeing through, Application of a colored cement slurry with a corresponding granulate in plastic coatings or painting.
Die angeführten Verfahren haben einige Nachteile, die sich im erhöhten Materialeinsatz und technologischen Aufwand äußern.The listed methods have some disadvantages, which are increased Express material use and technological effort.
Weiterhin ist bei der Granulatbeschichtung die Haftfestigkeit des Granulats nicht gegeben, so daß ein teilweises Abplatzen der Granulatteilchen noch erfolgt. Bei Eunststoffbeschichtungen und Anstrichen ist es außerdem noch so; daß diese erst nach der Erhärtung des Betons oder der Holzwolleleichtbauplatten aufgebracht werden können, der technologische Fluß damit verlängert wird.Furthermore, the adhesive strength of the granulate coating Granules not given, so that a partial flaking of the granules still he follows. It is also the case with plastic coatings and paints; that this is only applied after the concrete or the wood wool panels have hardened can be, the technological flow is thus extended.
Die Erfindung bezweckt eine Oberflächenbeschichtung der Betondachsteine und Betonelemente sowie mineralisch gebundenen Rolzwolleleichtbauplatten zu erreichen, die den bisherigen Verfahren in Bezug auf architektonische Gestaltung und physikalischen Eigenschaften gleichwertig ist, den technologischen Aufwand und damit die Kosten aber erheblich verringert.The invention aims at a surface coating of the concrete roof tiles and concrete elements as well as mineral-bonded rolled wool lightweight boards, which the previous procedures in terms of architectural design and physical Properties is equivalent to the technological effort and thus the costs but significantly reduced.
Die Erfindung hat die Aufgabe, die Betondachsteine und Betonelemente sowie mineralisch gebundenen Holzwolle leiciitb auplatten architektonisch farbig zu gestalten und die Dichtigkeit zu erhöhen, die Oberfläche also zu versiegeln.The invention has the task of the concrete roof tiles and concrete elements as well as mineral-bound wood wool lightly colored panels to design and to increase the tightness, i.e. to seal the surface.
Die Beschichtung kann direkt auf den Frischbeton oder die hergestellte mineralis ch gebundene Holzwollele ichtbauplatt e durch Aufspritzen oder Auftragen mit der Bürste erfolgen.The coating can be applied directly to the fresh concrete or the manufactured Minerally bound wood wool lightweight construction panel by spraying on or applying done with the brush.
Eine Warmbehandlung bis zu geringen Temperaturen verringert nicht den Effekt.A heat treatment down to low temperatures does not reduce the effect.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß ein Gemisch von Zement, Parbe, Wasser, Polyvinylacetat und Paraffinemulsion nach inniger Durchmischung auf den Betondachstein, das Betonelement sowie mineralisch gebundene HolzwoPlleleichtbauplatte aufgetragen werden.According to the invention the object is achieved in that a mixture of Cement, parbe, water, polyvinyl acetate and paraffin emulsion after thorough mixing on the concrete roof tile, the concrete element as well as minerally bound wooden wool lightweight construction panel be applied.
Durch den Zusatz von Polyvinylacetat-"Dispersionen zum Zement ergibt sich ein System von zwei Bindemitteln mit unterschiedlicher Erhärtung. Der Zement erhält seine Festigkeit durch die Reaktion zwischen Wasser und Calcium- und Siliciumoxyden.The addition of polyvinyl acetate "dispersions" to the cement results in a system of two binders with different levels of hardening. The cement gets its strength from the reaction between water and calcium and silicon oxides.
Diese Reaktion ist erst nach Wochen beendet. Die Plastdispersion dagegen bildet einen Film und gibt Wasser ab.This reaction takes weeks to end. The plastic dispersion on the other hand forms a film and releases water.
Die Erhärtung des Systems erfolgt, indem bei homogener Durchmischung der Plast in einzelnen Teilchen der Farbe und des Zementes völlig umhüllt. Innerhalb dieses Häutchens findet zuerst die hydraulische Zementbindung statt. Dadurch kommt es zu einer stabilen Verbindung zwischen Plast und Zement, die sich gegenseitig durchdringen.The hardening of the system takes place by homogeneously mixing the plastic is completely enveloped in individual particles of paint and cement. Within This membrane is where the hydraulic cement binding takes place first. This comes about it creates a stable bond between plastic and cement, which is mutually exclusive penetrate.
Folgende Mischungen sind geeignet: Beispiel 1 : 50 % Zement 5 - 10 % Polyvinylacetatdispersion, mit einer Teilchengröße von 0,8 -5zvm 4 - 10 % Farbe 25 - 40% Wasser O - 4 % Paraffinemulsion Beispiel 2 : 25 % Zement bis 15 % kieselsäurereiche Füller 0,09 - 2 mm Korngröße bis 45 % kieselsäurereiche Mehle < 0,09 mm 2,5 - 5% Polyvinylacetat, Teilchengröße von 0,8 -4 - 10 % Farbe O - 4 % Paraffinemulsion 25 - 40% WasserThe following mixtures are suitable: Example 1: 50% cement 5 - 10 % Polyvinyl acetate dispersion, with a particle size of 0.8-5zvm 4 - 10% color 25-40% water 0-4% paraffin emulsion Example 2: 25% cement to 15% high in silica Filler 0.09 - 2 mm grain size up to 45% silica-rich flours <0.09 mm 2.5 - 5% polyvinyl acetate, particle size from 0.8 -4 - 10% color O - 4% paraffin emulsion 25-40% water
