Masse til kleføning og belegning avMass for drying and coating
varmedeitimeplater ved fasadebekledning.thermal insulation boards for facade cladding.
Oppfinnelsen vedrører masse til klebning og belegning av varmedemmeplater, spesielt kunststoffhårdskumplater ved fasadebekledning. The invention relates to mass for gluing and covering heat-insulating boards, especially hard plastic foam boards for facade cladding.
En spesiell egenskap ved kunststoffhårdskum er deres lille varmeledningsevne, den ligger i størrelsesorden fra ca. 0,02 til 0,03 Kcal/mh°C. Denne egenskap nytter man til varme-isolering av boligbygninger, industrianlegg, kjølerom og lignende, idet man kler de indre og/eller ytre vegger med skumstoffplater. Skumstoffplatene anbringes på veggen som skal isoleres ved hjelp av et klebemiddel og dens frie overflate utstyres med et beskyttelsessjikt av samme materiale, som gjør platen motstandsdyktig mot mekanisk trykk, således at det unngås rissdannelse i det til-slutt påførte dekkpuss eller maling. Dette beskyttelsessjikt be-tegner man derfor som trykkutligningssjikt. A special property of synthetic rigid foam is their low thermal conductivity, which is in the order of magnitude from approx. 0.02 to 0.03 Kcal/mh°C. This property is used for thermal insulation of residential buildings, industrial plants, cold rooms and the like, by lining the inner and/or outer walls with foam panels. The foam boards are placed on the wall to be insulated using an adhesive and its free surface is equipped with a protective layer of the same material, which makes the board resistant to mechanical pressure, so that cracks are avoided in the finally applied covering plaster or paint. This protective layer is therefore referred to as a pressure compensation layer.
Undergrunner, hvorpå skumstoffplater påføres er av betong, murverk av tegl-, kalk-, farvet sandsten og andre sugende undergrunner har altså en ru overflate og en annen utvidelses-koeffisient en skumstoffplatene. Det er derfor nødvendig å påføre platen et klebemiddel som såvel kleber fast til undergrunnen som også til skumstoffplaten. Klebestoffsjiktet må etter herdning ha en tilstrekkelig elastisitet for å utligne de forskjellig ut-videlsesegenskaper av de to materialer, hvormed de er forbundet best mulig. Trykkutligningssjiktet må også ha en høyest mulig bøyefasthet for å tåle mekanisk påkjenningsmotstand. Det bør imidlertid også være vannavstøtende for å hindre en gjennomfukting av skumstoffplatene og dermed nedsettelse av varmedemmingen eller isoleringen. På den annen side bør vanndampgjennomtrengeligheten av trykkutligningssjiktet være så høy at det er sikret en tilstrekkelig vanndampdifusjon innenifra og utover. Subsurfaces on which foam panels are applied are concrete, masonry made of brick, limestone, colored sandstone and other absorbent subsurfaces therefore have a rough surface and a different coefficient of expansion than the foam panels. It is therefore necessary to apply an adhesive to the board that sticks firmly to the subsurface as well as to the foam board. After curing, the adhesive layer must have sufficient elasticity to compensate for the different expansion properties of the two materials, with which they are connected as best as possible. The pressure equalization layer must also have the highest possible bending strength to withstand mechanical stress resistance. However, it should also be water-repellent to prevent wetting through of the foam panels and thus reducing the heat barrier or insulation. On the other hand, the water vapor permeability of the pressure equalization layer should be so high that sufficient water vapor diffusion from the inside to the outside is ensured.
Fra DOS 1.471.100 er det kjent til en mørtelmasseFrom DOS 1,471,100, a mortar mass is known
å sette en homogen blanding av latekser av to polymerisater, hvor-ved elastisiteten samt bøyefastheten etter massens avbinding vesentlig forbedres. Klebefastheten av dette klebemiddel er imidlertid ikke alltid tilfredsstillende. to set a homogeneous mixture of latexes of two polymers, whereby the elasticity as well as the bending strength after the setting of the mass is significantly improved. However, the adhesive strength of this adhesive is not always satisfactory.
Ifølge DAS 2.018.214 lar denne ulempe seg unngåAccording to DAS 2.018.214, this disadvantage can be avoided
ved at man i stedet for latex-blandingen anvender en styren-butadien-kunststoffdispersjon. Med denne blanding fremstilte klebe- og trykkutligningssjikt har imidlertid en forholdsvis stor vannopptagsevne og en utilstrekkelig vanndampgjennomtrengelighet. by using a styrene-butadiene plastic dispersion instead of the latex mixture. Adhesive and pressure equalization layers produced with this mixture, however, have a relatively high water absorption capacity and insufficient water vapor permeability.
Til grunn for oppfinnelsen ligger derfor den oppgave å tilveiebringe en masse til klebning og belegning av varmedemmeplater, spesielt kunststoffhårdskumplater ved fasadekledning og som har høy klebefasthet til flatene som skal bindes; etter at massen er herdnet, skal de dannede sjikt ha god strekk-, bøye- og trykkfasthet, høy vannavvisningsevne og den ønskede vanndampgjennomtrengelighet . The invention is therefore based on the task of providing a mass for gluing and covering heat-insulating boards, especially plastic rigid foam boards for facade cladding and which has a high adhesive strength to the surfaces to be bonded; after the mass has hardened, the formed layers must have good tensile, bending and compressive strength, high water repellency and the desired water vapor permeability.
Oppgaven løses ved hjelp av en masse av 90-98 vekt% av en hydraulisk avbindende mørtel og eventuelt tilslagsstoffer, The task is solved using a mass of 90-98% by weight of a hydraulic binding mortar and possibly aggregates,
en vandig kunststoffdispersjon av et faststoffinnhold på 10-2 vekt% og referert til samlet faststoffinnhold av massen, 7-20 vekt% vann, til sammenklebning og belegning av varmedemmeplater ved fasadekledning, idet massen erkarakterisert vedat kunststoffdispersjonen består av 25-35 vekt% vinylester av syntetiske forgrenede monokarboksylsyrer med 9-11 C-atomer og 75-65 vekt% vinylacetat. an aqueous plastic dispersion with a solids content of 10-2% by weight and referred to the total solids content of the mass, 7-20% by weight water, for gluing together and coating heat-insulating panels for facade cladding, the mass being characterized by the fact that the plastic dispersion consists of 25-35% by weight vinyl ester of synthetic branched monocarboxylic acids with 9-11 C atoms and 75-65% vinyl acetate by weight.
Av enkelthetsgrunner benyttes i det følgendeFor reasons of simplicity, it is used in the following
i stedet for "vinylester av syntetiske forgrenede monokarboksylsyrer med 9-11 C-atomer" uttrykket "vinylester av forgrenede monokarboksylsyrer". instead of "vinyl ester of synthetic branched monocarboxylic acids with 9-11 C atoms" the expression "vinyl ester of branched monocarboxylic acids".
Det kunne ikke forutsees at den stilte oppgave lot seg løse ved innarbeidelse av en kunststoffdispersjon av vinylester av forgrenede monokarboksylsyrer og vinylacetat i en mørtelblan-ding, der et sjikt som er fremstilt med kunststoffdispersjonen og uten mørtel har dårligere mekaniske og vannfastheter. It could not be foreseen that the task set could be solved by incorporating a plastic dispersion of vinyl ester of branched monocarboxylic acids and vinyl acetate in a mortar mixture, where a layer prepared with the plastic dispersion and without mortar has poorer mechanical and water resistance.
Vinylesteren av forgrenede monokarboksylsyrer er oppnåelig i handelen som teknisk blanding under varemerket "Veo-Va". Forholdet mellom vinylester og forgrenede monokarboksylsyrer og vinylacetat bør ligge innen de ovennevnte grenser. Ved større vinylacetat-del øker vannopptagelsesevnen. Går man med vinylacetat-innholdet under 65 vekt%, oppnås ikke mer enn noen tilstrekkelig klebefasthet. Dispersjonen kan fremstilles på kjent måte ved emulsjonspolymerisasjon. De monomere emulgeres ved hjelp av en emulgator i vann. Som polymerisasjonskatalysator benytter man en per-forbindelse, f.eks. kaliumpersulfat. Det fremkommer en dispersjon av en partikkelstørrelse i området på ca. 0,04-0,002 mm. Partikkelstørrelsen er uten betydning for egenskapene av massen ifølge oppfinnelsen. Dispersjonens faststoffinnhold ligger van-ligvis i området på 40-70 vekt%, fortrinnsvis utgjør den 50 vekt%. For økning av dispersjonsstabilitet overfor den hydraulisk avbindende mørtel, kan det til den på i og for seg kjent måte settes en stabilisator, f.eks. en polyglykol, en polyeter, i en mengde på ca. 0,1-3 vekt% referert til dispersjonens faststoffinnhold. The vinyl ester of branched monocarboxylic acids is commercially available as a technical mixture under the trademark "Veo-Va". The ratio between vinyl ester and branched monocarboxylic acids and vinyl acetate should be within the above limits. With a greater proportion of vinyl acetate, the water absorption capacity increases. If you go with the vinyl acetate content below 65% by weight, no more than a sufficient adhesive strength is achieved. The dispersion can be prepared in a known manner by emulsion polymerization. The monomers are emulsified using an emulsifier in water. A per compound is used as a polymerization catalyst, e.g. potassium persulfate. A dispersion of a particle size in the range of approx. 0.04-0.002 mm. The particle size is of no importance for the properties of the mass according to the invention. The solids content of the dispersion is usually in the range of 40-70% by weight, preferably 50% by weight. To increase dispersion stability in relation to the hydraulic setting mortar, a stabilizer can be added in a manner known per se, e.g. a polyglycol, a polyether, in an amount of approx. 0.1-3% by weight referred to the solids content of the dispersion.
Som hydraulisk avbindende mørtel kan det anvendes kalk-, gips-,sementmørtel eller lignende. Det foretrekkes Portlandsement. Egnede tilslagsstoffer er sand, sten, kis, chamotte, asbest og lignende. Av økonomiske grunner foretrekkes sand. På ' en vektdel sement kan det tilblandes inntil ca. 4 vektdeler sand. Lime, gypsum, cement mortar or the like can be used as a hydraulic binding mortar. Portland cement is preferred. Suitable aggregates are sand, stone, kieselguhr, chamotte, asbestos and the like. For economic reasons, sand is preferred. One part by weight of cement can be mixed with up to approx. 4 parts by weight of sand.
For forbedring av mørtelens forarbeidbarhet, kan det innarbeides 0,1-3 % av et fortykningsmiddel, fortrinnsvis metylcellulose, med en viskositetsinnstilling på 1000 cP av en 2 %-ig vandig oppløsning. To improve the workability of the mortar, 0.1-3% of a thickener, preferably methylcellulose, can be incorporated with a viscosity setting of 1000 cP of a 2% aqueous solution.
Massen fremstilles ved sammenblanding av den tørre mørtel, eventuelt tilslagsstoffene og kunststoffdispersjonen. Hensiktsmessig foretar man blandingen i en mørtelblander, idet man ifyller kunststoffdispersjonen og tilblander den tørre mørtel og eventuelt tilslagsstoffer. Mindre blandinger fremstilles i et tilsvarende stort rørverk, idet man for det meste foretrekker å ifylle mørtel og tilslagsstoffet og å innblande kunststoffdispersjonen. The mass is produced by mixing the dry mortar, possibly the aggregates and the plastic dispersion. Appropriately, the mixture is carried out in a mortar mixer, filling in the plastic dispersion and mixing in the dry mortar and any aggregates. Smaller mixtures are produced in a correspondingly large pipework, as it is mostly preferred to fill in mortar and the aggregate and to mix in the plastic dispersion.
Med massen ifølge oppfinnelsen kan varmedemmeplater av fenolharpiksskum, polystyrenharpiksskum, polyuretanharpiksskum og på mineralsk basis, f.eks. gassbetong, glassfibre, klebes og belegges. With the mass according to the invention, heat insulation boards made of phenolic resin foam, polystyrene resin foam, polyurethane resin foam and on a mineral basis, e.g. aerated concrete, glass fibres, are glued and coated.
Som det fremgår av figuren påføres på murverket 1 et klebesjikt 2 av massen ifølge oppfinnelsen i en tykkelse på minst 5 mm. Når murverket har en meget rå overflate, bør klebestoffsjiktet utgjøre 20mm. Massen behøver ikke å påføres som gjennomgående sjikt, i praksis påføres den punktformet eller i strimler. Deretter pålegges skumstoffplaten 3 med svakt trykk og etter at klebesjiktet 2 minst delvis er avbundet, påføres på den frie overflate av skumstoffplaten 3 et trykkutligningssjikt 4 av massen ifølge oppfinnelsen i en tykkelse på ca. 3-8 mm. For ytterligere å forbedre strekk- og bøyefastheten kan dette sjikt utstyres med en armering av glassfibervevnad eller -matte. Etter avbindingen av trykkutligningssjiktet utstyres det med en vanlig puss eller maling' 5. As can be seen from the figure, an adhesive layer 2 of the mass according to the invention is applied to the masonry 1 in a thickness of at least 5 mm. When the masonry has a very rough surface, the adhesive layer should be 20mm. The mass does not need to be applied as a continuous layer, in practice it is applied point-wise or in strips. The foam sheet 3 is then applied with slight pressure and, after the adhesive layer 2 has been at least partially debonded, a pressure compensation layer 4 of the mass according to the invention is applied to the free surface of the foam sheet 3 in a thickness of approx. 3-8 mm. To further improve the tensile and bending strength, this layer can be equipped with a reinforcement of glass fiber fabric or mat. After the binding of the pressure compensation layer, it is equipped with a normal plaster or paint' 5.
Oppfinnelsen og de fordeler den medfører skal forklares nærmere ved hjelp av følgende eksempler: The invention and the advantages it entails shall be explained in more detail by means of the following examples:
Ved alle eksempler ble det i et rørverk blandetIn all examples, it was mixed in a pipework
70 vekt% sand (type H 32) og 20 vekt% sement (Portlandsement,70% by weight sand (type H 32) and 20% by weight cement (Portland cement,
type 450) med hverandre. Til denne blanding ble det hver gang satt 6-10 vekt% kunststoffdispersjon av et faststoffinnhold på type 450) with each other. To this mixture, 6-10% by weight of plastic dispersion of a solids content was added each time
50% og 14-10 vekt% vann og det hele blandet. De 6-10 vekt% av 50 %-ig dispersjon tilsvarer en sement : polymerisat-forhold på 1:0,15 - 1:0,25. Hvilke kunststoffdispersjon som ble anvendt i de enkelte eksempler og hvor stor hver gang forholdet sement:dispersjon var fremgår av tabellen, hvori alle eksempler er oppstilt. 50% and 14-10% water by weight and the whole thing mixed. The 6-10% by weight of a 50% dispersion corresponds to a cement:polymer ratio of 1:0.15 - 1:0.25. Which plastic dispersion was used in the individual examples and how large each time the cement:dispersion ratio was can be seen from the table, in which all examples are listed.
I alle eksempler ble det for forbedring av for-arbeidbarheten til blandingen satt en metylcellulose, hvis 2%ige vandige oppløsning har en viskositet på 1000 cP. På 75 vektdeler dispersjon ble det satt 25 vektdeler av en 2%-ig vandig metyl-celluloseoppløsning. In all examples, to improve the workability of the mixture, a methylcellulose was added, whose 2% aqueous solution has a viscosity of 1000 cP. 25 parts by weight of a 2% aqueous methyl cellulose solution were added to 75 parts by weight of the dispersion.
Den ved hvert eksempel dannede mørtelmasse ble undersøkt på sine egenskaper. Dertil ble det fremstilt 5 mm tykke prøvelegemer, etter avbindingen, en tørkning på 14 dager ved 23°C og 60% relativ luftfuktighet, undersøkt på følgende egenskaper: The mortar mass formed in each example was examined for its properties. In addition, 5 mm thick test specimens were produced, after debonding, drying for 14 days at 23°C and 60% relative humidity, examined for the following properties:

En 50 x 50 x 50 mm stor terning av polystyrenhård-skum sammenklebes mellom to 50 x 60 x 5 mm store asbestsementplater med den i hvert eksempel dannede mørtelmasse. Etter en tørkning på 14 dager ved 23°C og 60% relativ luftfuktighet rives de to asbest sementplater av prøvelegemet fra hverandre med en hastighet på 20 mm/min. og avrivningen av polystyrenhårdskummet vurdert på grenseflaten. A 50 x 50 x 50 mm cube of rigid polystyrene foam is glued together between two 50 x 60 x 5 mm asbestos cement sheets with the mortar mass formed in each example. After drying for 14 days at 23°C and 60% relative humidity, the two asbestos cement sheets of the specimen are torn apart at a speed of 20 mm/min. and the tear-off of the rigid polystyrene foam assessed at the interface.
