Description
Den foreliggende oppfinnelse angår fugecement som er egnet til fylling av spalter i overflaten av bygningskonstruksjoner, nærmere bestemt fuger mellom til hinannen grensende veggplater i en vegg- eller himlingskonstruksjon, så der fås en glatt ferdig overflate. The present invention relates to joint cement which is suitable for filling gaps in the surface of building constructions, more specifically joints between adjacent wall panels in a wall or ceiling construction, so that a smooth finished surface is obtained.
Vanlige fugesammensetninger består av mineralsk fyllstoff, f.eks. malt kalksten, og bindemiddel, vanligvis en organisk polymer, foruten tilsetninger som skal forbedre eller innstille bearbeidingsegenskapene av sammensetningen. Sammensetningen blandes med den mengde vann som er nødvendig for oppnåelse av den ønskede arbeidskonsistens. Sammensetningene kan selges i en tørr form som lett kan blandes med vann, men etter påføring vil de i alle tilfelle tørke ved fordampning av det tilsatte vann. I fuktige omgivelser kan tørketiden være usedvanlig lang, f.eks. så meget som 6 uker, og fullfø-relsen av den angjeldende bygning vil da bli tilsvarende for-sinket. Common joint compositions consist of mineral filler, e.g. ground limestone, and binder, usually an organic polymer, in addition to additives to improve or adjust the processing properties of the composition. The composition is mixed with the amount of water necessary to achieve the desired working consistency. The compositions can be sold in a dry form which can easily be mixed with water, but after application they will in any case dry by evaporation of the added water. In humid environments, the drying time can be exceptionally long, e.g. as much as 6 weeks, and the completion of the relevant building will then be correspondingly delayed.
Det er en hensikt med den foreliggende oppfinnelse å skaffe en fugesammensetning som herdner relativt raskt og er mindre avhengig av værforholdene enn vanlige sammensetninger, men som i det minste opprettholder egenskapene av vanlige sammensetninger med hensyn til bearbeidbarhet og oppnåelse av en glatt overflate. It is an aim of the present invention to provide a grout composition which hardens relatively quickly and is less dependent on weather conditions than ordinary compositions, but which at least maintains the properties of ordinary compositions with regard to workability and the achievement of a smooth surface.
I henhold til oppfinnelsen er der skaffet en fugecement for blanding med vann inneholdende 35 - 95 vektprosent gips med en partikkelstørrelse på under 150 ym, 0-64 vektprosent inert mineralsk fyllstoff med en partikkelstørrelse på under 100 ym og 1 - 10 vektprosent organisk polymert bindemiddel. According to the invention, a joint cement for mixing with water containing 35-95% by weight of gypsum with a particle size of less than 150 ym, 0-64% by weight of inert mineral filler with a particle size of less than 100 ym and 1-10% by weight of organic polymeric binder has been provided.
Tilsetninger såsom ytterligere fyllstoff, stivningsretarderende tilsetning for gipsen, fargestoffer og antiskumme-midler kan innlemmes. Additives such as additional filler, setting retarder for the plaster, dyes and antifoams can be incorporated.
Som følge av innlemmelsen av et så raskt stivnende hyd-raulisk materiale som gips vil cementen ifølge den foreliggende oppfinnelse ikke være avhengig av fordampning av vann for å herdne, og sprekker, spalter eller fuger som fylles med denne cementrkan derfor være klar for ytterligere over-flateoperasjoner på en forutberegnelig kort tid uavhengig av de atmosfæriske betingelser. Herdingstiden kan innstilles As a result of the incorporation of such a rapidly hardening hydraulic material as gypsum, the cement of the present invention will not depend on the evaporation of water to harden, and cracks, crevices or joints filled with this cement water will therefore be ready for further over- surface operations in a predictable short time regardless of the atmospheric conditions. The curing time can be set
ved bruk av vanlige regulerende midler for herdehastighetenusing normal curing rate control agents
av det angjeldende cementmateriale. Egnede herdetider for disse cementer kan ligge på mellom 30 minutter og 6 timer avhengig av hva brukeren foretrekker. Med en cement med en her-detid på 2 timer kan en fuge,inklusive påføringen av strimler, fylles på 4.timer. of the cement material in question. Suitable curing times for these cements can be between 30 minutes and 6 hours, depending on what the user prefers. With a cement with a setting time of 2 hours, a joint, including the application of strips, can be filled in 4 hours.
Den foretrukne gips for bruk i oppfinnelsen er hemihyd-ratgips med en partikkelstørrelse på under 150 ym fremstilt ved vanlige fremgangsmåter. Slike gipser har fra naturens side en stivningstid på bare få minutter og må retarderes for å gi brukeren av cementen tilstrekkelig tid for påføring og glatting. Vanlige retarderende midler, f.eks. sitronsyre, kan anvendes til dette formål. The preferred gypsum for use in the invention is hemihydrate gypsum with a particle size of less than 150 µm produced by usual methods. Such plasters naturally have a setting time of only a few minutes and must be retarded to give the user of the cement sufficient time for application and smoothing. Common retarding agents, e.g. citric acid, can be used for this purpose.
Inerte fyllstoffer i forbindelse med oppfinnelsen bør være kjemisk inerte og velges for å gi ønskede fukte- og bearbeidingsegenskaper. Kalsiumkarbonat, f.eks. i form av malt kalksten, er velkjent som fyllstoff i vanlige fugesammensetninger, og dette gjelder også talkum. Gips utfører i seg selv en fyllingsfunksjonfog mengden av inerte fyllstoffer kan derfor reduseres. Den foretrukne partikkelstørrelse for den malte kalksten er på under 100 ym. For talkum foretrekkes en partikkelstørrelse på under 40 ym. En leire som f.eks. kaolinitt eller montmorillonitt kan tilsettes hvis det skulle være ønsket, f.eks. i en mengde på 0 - 2 vektprosent. Inert fillers in connection with the invention should be chemically inert and selected to provide desired wetting and processing properties. Calcium carbonate, e.g. in the form of ground limestone, is well known as a filler in common grout compositions, and this also applies to talc. Gypsum itself performs a filling function, and the amount of inert fillers can therefore be reduced. The preferred particle size for the ground limestone is less than 100 µm. For talc, a particle size of less than 40 ym is preferred. A clay such as kaolinite or montmorillonite can be added if desired, e.g. in an amount of 0 - 2 percent by weight.
Det polymere bindemiddel tjener til å styrke den stivnede cement, men bidrar også til cementens bearbeidingsegenskaper. The polymeric binder serves to strengthen the hardened cement, but also contributes to the processing properties of the cement.
Bindemiddelet bør være vannoppløselig eller vanndisper-gerbart, og-den foretrukne polymer er pblyvinylalkohol. Stivelse kan også tilsettes og bidrar til cementens bearbeidingsegenskaper. The binder should be water-soluble or water-dispersible, and the preferred polymer is lead vinyl alcohol. Starch can also be added and contributes to the processing properties of the cement.
Andre tilsetningsstoffer kan innlemmes, f.eks. et avskummingsmiddel for å hindre dannelse av bobler og fargestoffer for å gi den stivnede cement den ønskede fargetone, f.eks. slik at den passer til den elfenbenlignende farge av dekkpa-piret på gipsplater. Other additives can be incorporated, e.g. a defoamer to prevent the formation of bubbles and coloring agents to give the set cement the desired color tone, e.g. so that it matches the ivory-like color of the covering paper on plasterboard.
Foretrukne oppskrifter i henhold til oppfinnelsen erPreferred recipes according to the invention are
som følger:as follows:
De tørre cementblandinger i henhold til oppfinnelsen The dry cement mixtures according to the invention
med en sammensetning som angitt ovenfor, har fremragende lag-ringsegenskaper hvis de oppbevares i en lukket beholder. For lengst mulig levetid bør de forsegles i en sekk av hovedsakelig ugjennomtrengelig plast, f.eks. polyeten. Blandingen kan lett blandes med den foreskrevne mengde vann like før bruk. with a composition as stated above, have excellent storage properties if kept in a closed container. For the longest possible life, they should be sealed in a bag of mainly impermeable plastic, e.g. polyethylene. The mixture can be easily mixed with the prescribed amount of water just before use.
Oppfinnelsen gjør det mulig å fremstille fugecementer som bortsett fra den allerede nevnte fordel med hensyn til forutsigelig og rask stivning har følgende egenskaper: lett blanding med vann til en glatt, kremlignende pasta, gode "våtkant"-egenskaper, god utstrykningsevne til tynne kanter (good feathering properties), god adhesjon og fremragende spaltefyllingsevne med minimal krymping. Det herdede cement-skikt kan slipes hvis det skulle være ønskelig. Som følge av disse fremragende egenskaper er cementen ifølge den foreliggende oppfinnelse av interesse for en rekke formål, her-under påføring ved hjelp av håndverktøy eller med maskin, men spesielt når fuger skal fylles, spesielt i overflaten av bygge-konstruksjoner og lettvegger som allerede omtalt. The invention makes it possible to produce joint cements which, apart from the already mentioned advantage with regard to predictable and fast setting, have the following properties: easy mixing with water to a smooth, cream-like paste, good "wet edge" properties, good spreadability to thin edges (good feathering properties), good adhesion and excellent gap-filling ability with minimal shrinkage. The hardened cement layer can be sanded if desired. As a result of these outstanding properties, the cement according to the present invention is of interest for a number of purposes, including application using hand tools or by machine, but especially when joints are to be filled, especially in the surface of building constructions and light walls as already mentioned .
Oppfinnelsen skaffer altså også en fremgangsmåte til fylling av sprekker eller fuger i konstruksjoner ved tilføring av en cement til sprekken eller fugen, hvoretter cementen tillates å stivne eller herdne i sprekken eller fugen. The invention therefore also provides a method for filling cracks or joints in structures by adding a cement to the crack or joint, after which the cement is allowed to solidify or harden in the crack or joint.
