Definitions
- the invention relates to an insulated outer wall panel of a known type, consisting of an insulating panel which is provided with a plaster layer which is composed of granular and / or powdery insulating materials, a glass fiber fabric covered with a plastic film and a cement binder which has been mixed with water-mixed plastic dispersion .
- Exterior wall insulation systems with plastic foams are known which are provided with dispersion plasters or mineral plasters throughout.
- dispersion plasters or mineral plasters throughout.
- these systems can only be properly carried out by handicraft companies that are able to implement the special processing guidelines of the manufacturers.
- the disadvantage is that such systems cannot be used by do-it-yourselfers.
- Prefabricated interior wall claddings are also known, in which a fine plaster of cement PZ 35 F polystyrene foam powder and glass scrim arranged in the middle is applied to a polystyrene foam panel, which is mixed with water mixed with plastic dispersion (solids content up to 4%).
- Such interior wall cladding has proven itself in weatherproof walls.
- rain and frost also act, which leads to instability of the glass fibers as a result of the reaction with the cement present.
- the serviceability in particular the strength and freedom from distortion, cannot be maintained in the long run. This disadvantage is not eliminated by a coating with a plastic film which is customary in the processing of glass fibers.
- the invention has for its object to find a visible, insulating cladding for an external wall exposed to wind and weather, which can also be installed by individual non-specialists flawlessly and with little construction site work, and in addition to a definable thermal insulation has sufficient mechanical strength and durability .
- the glass fiber fabric is thickly coated with at least one hydrolytically stable, water-insoluble polymer layer of 10 to 35% by weight, in particular 15 to 25% by weight, of the polymer, based on the glass fiber.
- the outer wall plate surprisingly becomes insensitive to moisture that may be exerted from the outside, despite the porous plaster layer, because the glass scrim can no longer be attacked by the cement due to the applied protective layer, so that the original material properties are retained .
- the power transmission between plaster and glass fibers without additional adhesion promoters, such as functional alkoxysilanes is very intimate, so that the outer wall panel has a high strength. This largely avoids the risk of cracks in the event of temperature stresses.
- the secure bond also reduces sensitivity when handling, attaching and using.
- the flatness of the outer wall panel is preserved, which makes it easier to work properly, so that the outer wall panel can also be used for home-made construction.
- the plastic coating can be applied to the glass fibers in various ways.
- the glass fibers can be drawn through a solution, dispersion or melt of the plastic as a glass fiber bundle of the desired number of individual filaments with a fiber diameter in the range of approximately 5 to 40 1 1m or coated with the plastic melt using an extruder in a special nozzle head.
- Polymers made from compounds containing double bonds such as, for example, Ethylene, propylene, butadiene, styrene, vinyl esters, acrylic and methacrylic acid esters, which also include copolymers of two or more monomer compounds.
- polyurethane, epoxy resins and polysiloxanes can be used as polymer coatings.
- Polyvinyl acetate is particularly preferred.
- insulation boards i.a. Rigid PUR foam, rigid polystyrene foam, glass foam and insulating boards made of mineral or organic components are used, while insulating materials made of the aforementioned materials with a diameter of 0 to 2 mm are used as additives for the plaster layer.
- insulating materials made of the aforementioned materials with a diameter of 0 to 2 mm are used as additives for the plaster layer.
Abstract
Description
Die Erfindung betrifft eine gedämmte Aussenwandplatte bekannter Art, bestehend aus einer Dämmplatte, die mit einer Putzschicht versehen ist, welche sich aus körnigen und/oder pulverigen Isolierstoffen, einem mit einem Kunststofffilm überzogenen Glasfasergelege und einem Zementbinder, der mit Kunststoffdispersion versetztem Wasser angemacht wurde, zusammensetzt.The invention relates to an insulated outer wall panel of a known type, consisting of an insulating panel which is provided with a plaster layer which is composed of granular and / or powdery insulating materials, a glass fiber fabric covered with a plastic film and a cement binder which has been mixed with water-mixed plastic dispersion .
Bekannt sind Aussenwand-Dämmsysteme mit Kunststoffschäumen, die durchgehend mit Dispersionsputzen oder mineralischen Putzen versehen sind. Infolge temperaturbedingter Bewegungen kommt es vor allem im Bereich über den Fugen der Dämmelemente leicht zu Überbelastungen, was dann eine Rissebildung zur Folge hat. Deshalb können diese Systeme einwandfrei nur von Handwerksfirmen ausgeführt werden, welche in der Lage sind, die besonderen Verarbeitungsrichtlinien der Hersteller in die Tat umzusetzen. Von Nachteil ist also, dass derartige Systeme nicht von Do-it-yourselfern angewendet werden können.Exterior wall insulation systems with plastic foams are known which are provided with dispersion plasters or mineral plasters throughout. As a result of temperature-related movements, there is a slight overload, especially in the area over the joints of the insulation elements, which then leads to the formation of cracks. For this reason, these systems can only be properly carried out by handicraft companies that are able to implement the special processing guidelines of the manufacturers. The disadvantage is that such systems cannot be used by do-it-yourselfers.
Bekannt sind auch vorgefertigte Innenwandverkleidungen, bei denen auf einer Polystyrolschaumplatte ein Feinputz aus Zement PZ 35 F Polystyrolschaummehl und mittig angeordnetem Glasgelege aufgebracht ist, der mit einem durch Kunststoffdispersion (Feststoffgehalt bis zu 4%) versetztem Wasser angemacht ist. Derartige Innenwandverkleidungen haben sich bei wettergeschützten Wänden bewährt. Beim Einbau an der Aussenwand wirkt dagegen zusätzlich Regen und Frost ein, der zu einer Instabilität der Glasfasern infolge der Reaktion mit dem anwesenden Zement führt. Die Gebrauchstüchtigkeit, insbesondere die Festigkeit und Verzugsfreiheit, ist auf Dauer nicht aufrechtzuerhalten. Dieser Nachteil wird auch durch eine bei der Verarbeitung von Glasfasern üblichen Beschichtung mit einem Kunststoffilm nicht beseitigt.Prefabricated interior wall claddings are also known, in which a fine plaster of cement PZ 35 F polystyrene foam powder and glass scrim arranged in the middle is applied to a polystyrene foam panel, which is mixed with water mixed with plastic dispersion (solids content up to 4%). Such interior wall cladding has proven itself in weatherproof walls. When installed on the outer wall, on the other hand, rain and frost also act, which leads to instability of the glass fibers as a result of the reaction with the cement present. The serviceability, in particular the strength and freedom from distortion, cannot be maintained in the long run. This disadvantage is not eliminated by a coating with a plastic film which is customary in the processing of glass fibers.
Der Erfindung liegt die Aufgabe zugrunde, eine sichtbare, dämmende Verkleidung für eine dem Wind und Wetter ausgesetzte Aussenwand zu finden, welche auch von einzelnen Nicht-Fachleuten einwandfrei und mit geringem Baustellenaufwand angebracht werden kann, sowie neben einer festlegbaren Wärmedämmung ausreichende mechanische Festigkeit und Beständigkeit besitzt.The invention has for its object to find a visible, insulating cladding for an external wall exposed to wind and weather, which can also be installed by individual non-specialists flawlessly and with little construction site work, and in addition to a definable thermal insulation has sufficient mechanical strength and durability .
Die Aufgabe wird erfindungsgemäss dadurch gelöst, dass das Glasfasergelege mit mindestens einer hydrolytisch stabilen, wasserunlöslichen Polymerschicht von 10 bis 35 Gew.%, insbesondere 15 bis 25 Gew.%, des Polymers, bezogen auf die Glasfaser, dick ummantelt ist.The object is achieved according to the invention in that the glass fiber fabric is thickly coated with at least one hydrolytically stable, water-insoluble polymer layer of 10 to 35% by weight, in particular 15 to 25% by weight, of the polymer, based on the glass fiber.
Durch die hydrolytisch stabile, wasserunlösliche Polymerschicht über der Glasfaser wird die Aussenwandplatte trotz evtl. poriger Putzschicht überraschenderweise unempfindlich gegen von aussen einwirkende Feuchtigkeit, denn das Glasgelege kann wegen der aufgebrachten dichten Schutzschicht nicht mehr durch den Zement angegriffen werden, so dass die ursprünglichen Materialeigenschaften erhalten bleiben. Weiter hat sich gezeigt, dass trotz der verhältnismässig dicken Ummantelung mit Polymeren die Kraftübertragung zwischen Putz und Glasfasern ohne zusätzliche Haftvermittler, wie z.B. funktionelle Alkoxysilane, sehr innig ist, so dass die Aussenwandplatte eine hohe Festigkeit besitzt. Dadurch wird eine Rissgefahr bei Temperaturspannungen weitgehend vermieden. Auch wird durch den sicheren Verbund die Empfindlichkeit bei der Handhabung bzw. bei der Anbringung und bei der Nutzung herabgesetzt. Darüber hinaus bleibt auch die Planizität der Aussenwandplatte erhalten, was eine saubere Arbeit erleichtert, so dass die Aussenwandplatte auch für den Eigenbau eingesetzt werden kann.Thanks to the hydrolytically stable, water-insoluble polymer layer over the glass fiber, the outer wall plate surprisingly becomes insensitive to moisture that may be exerted from the outside, despite the porous plaster layer, because the glass scrim can no longer be attacked by the cement due to the applied protective layer, so that the original material properties are retained . It has also been shown that, despite the relatively thick coating with polymers, the power transmission between plaster and glass fibers without additional adhesion promoters, such as functional alkoxysilanes, is very intimate, so that the outer wall panel has a high strength. This largely avoids the risk of cracks in the event of temperature stresses. The secure bond also reduces sensitivity when handling, attaching and using. In addition, the flatness of the outer wall panel is preserved, which makes it easier to work properly, so that the outer wall panel can also be used for home-made construction.
Die Kunststoffbeschichtung kann auf verschiedene Weise auf die Glasfasern aufgebracht werden. Beispielsweise können die Glasfasern als Glasfaserbündel der gewünschten Anzahl von Einzelfilamenten mit Faserdurchmesser im Bereich von ca. 5 bis 40 11m durch eine Lösung, Dispersion oder Schmelze des Kunststoffs hindurchgezogen oder mit der Kunststoff-Schmelze mit Hilfe eines Extruders in einem speziellen Düsenkopf ummantelt werden.The plastic coating can be applied to the glass fibers in various ways. For example, the glass fibers can be drawn through a solution, dispersion or melt of the plastic as a glass fiber bundle of the desired number of individual filaments with a fiber diameter in the range of approximately 5 to 40 1 1m or coated with the plastic melt using an extruder in a special nozzle head.
Als Polymerüberzüge eignen sich Polymerisate aus Doppelbindungen enthaltenden Verbindungen, wie z.B. Ethylen, Propylen, Butadien, Styrol, Vinylester, Acryl- und Methacrylsäureester, wobei auch Copolymere aus zwei oder mehreren Monomerverbindungen eingeschlossen sind. Daneben kommen als Polymerüberzüge Polyurethane, Epoxidharze und Polysiloxane in Frage. Besonders bevorzugt wird Polyvinylacetat.Polymers made from compounds containing double bonds, such as, for example, Ethylene, propylene, butadiene, styrene, vinyl esters, acrylic and methacrylic acid esters, which also include copolymers of two or more monomer compounds. In addition, polyurethane, epoxy resins and polysiloxanes can be used as polymer coatings. Polyvinyl acetate is particularly preferred.
Als Dämmplatten können u.a. PUR-Hartschaum, Polystyrol-Hartschaum, Glasschaum und Dämmplatten aus mineralischen oder organischen Bestandteilen verwendet werden, während als Zuschlagstoffe für die Putzschicht Isolierstoffe aus vorher genannten Werkstoffen mit einem Durchmesser von 0 bis 2 mm eingesetzt werden. Weiter ist auch ein geringer Zusatz an Putzsand, insbesondere Quarzsand, möglich. Auch Farbzusätze sind denkbar.As insulation boards, i.a. Rigid PUR foam, rigid polystyrene foam, glass foam and insulating boards made of mineral or organic components are used, while insulating materials made of the aforementioned materials with a diameter of 0 to 2 mm are used as additives for the plaster layer. A small addition of plaster sand, in particular quartz sand, is also possible. Color additions are also conceivable.
Weiter kann eine Verringerung des Feuchtigkeitsangriffes durch Schutz- bzw. Farbanstriche erfolgen, was insbesondere bei dünnen Putzschichten (d < 5 mm) Vorteile bringt.Furthermore, the attack of moisture by protective or colored coatings can be reduced, which is particularly advantageous for thin layers of plaster (d <5 mm).
