Description
Lim som inneholder finfordelt organiskGlue containing finely divided organic
pulver basert på alkalisilikatløsningerpowder based on alkali silicate solutions
Til varmeisolering av bygninger eller bygningsseksjoner benyttes bl.a. plater av skumplast, spesielt av polystyrol-skumstoff. Og-så synlige flater, f.eks. værelsestak, fremstilles ved bruk av slike plater. Platene festes så å si utelukkende ved klebning, ved bruk av klebestoffer på basis av kunstharpiks-dispersjoner, som dog har betydelige ulemper. Klebestoffer på basis av kunstharpiks-dispersjoner er ikke bare kostbare, men også brennbare. For thermal insulation of buildings or building sections, e.g. sheets of foam plastic, especially polystyrene foam. Also visible surfaces, e.g. room ceiling, is produced using such plates. The plates are attached, so to speak, exclusively by gluing, using adhesives based on synthetic resin dispersions, which however have significant disadvantages. Adhesives based on synthetic resin dispersions are not only expensive, but also flammable.
I handelen betegnes de som "tungt antennelige. Ved et klebestoff-belegg på 500-600 g/m , som er vanlig, vil bygningens eller byg-ningsseks jonens brannsikkerhet i hoy grad påvirkes. En annen ulempe ved bruk av disse kjente klebestoffer er at man må ta miljøbelastningen ved organiske polymerer eller flammebeskyttel-sesmidler hhv. deres forbrenningsprodukter med på kjopet. In the trade, they are referred to as "highly flammable. With an adhesive coating of 500-600 g/m, which is common, the fire safety of the building or building section will be greatly affected. Another disadvantage of using these known adhesives is that the environmental impact of organic polymers or flame retardants or their combustion products must be included in the purchase.
Oppfinnelsen går ut på å tilveiebringe et klebestoff til klebning av skumplastplater, som er rimelig i produksjon, fullstendig flammesikkert, ikke forårsaker miljobelastninger og gir god klebevirkning. The invention aims to provide an adhesive for gluing foam plastic sheets, which is inexpensive to produce, completely flameproof, does not cause environmental damage and provides good adhesive effect.
Denne oppgave loses ifolge oppfinnelsen ved et klebestoff på basis av alkalisilikatopplosninger, som inneholder et finfordelt, According to the invention, this task is solved by an adhesive based on alkali silicate solutions, which contains a finely divided,
i uorganisk pulver og som utmerker seg ved en opplosning av ett eller flere alkalisalter med et innhold av ett eller flere materialer som mineralogisk inneholder mer enn 15% kaolinitt. in inorganic powder and which is distinguished by a solution of one or more alkali salts with a content of one or more materials which mineralogically contain more than 15% kaolinite.
Klebestoffet ifolge oppfinnelsen er ikke bare flammesikkert, men virker endog beskyttende mot brann, idet det vil ha en ikke ube-tydelig hemmende virkning på varmestråling som folge av brann. Det har utmerket klebevirkning og vil hverken skape miljovern-problemer ved bruk eller ved påvirkning av brann eller varmestrå ling, idet det utelukkende inneholder komponenter som også forekommer i naturen. The adhesive according to the invention is not only flameproof, but also acts as a protective against fire, as it will have a not insignificant inhibitory effect on heat radiation as a result of fire. It has an excellent adhesive effect and will neither create environmental protection problems during use nor when exposed to fire or heat radiation, as it exclusively contains components that also occur in nature.
I tysk utlegningsskrift 1 092 586 beskrives et vannglass-klebestoff, som inneholder findelt uorganisk pulver, for kontinuerlig klebning av papp-baner i bolgepapp-maskiner, hvilket erkarakterisert vedat klebestoffet i det vesentlige består av en vann-glass-opplbsning og s.k. "Neuburger" kritt. Klebning av papp-baner stiller andre krav til klebestoffet enn klebning av skumplastplater, bl.a. fordi det i forste tilfelle dreier seg om hydrofile og i sistnevnte tilfelle om hydrofobe materialer. Kle-bemekanismen i dette kjente tilfelle er dessuten basert på en strukturendring i det kolloidale system, som er spesiell for komponentene, idet det understrekes at motsatt virkning vil oppnås ved bruk av kaolin i stedet for "Neuburger"-kritt under for ovrig like betingelser. "Neuburger"-krittets egnethet for klebning av papp-baner baserer seg på den spesifikke fysikalske struktur av dette materiale, som klart angitt i nevnte tyske utlegningsskrift . German specification 1 092 586 describes a water-glass adhesive, which contains finely divided inorganic powder, for continuous gluing of cardboard webs in corrugated cardboard machines, which is characterized by the fact that the adhesive essentially consists of a water-glass solution and so-called "Neuburger" chalk. Gluing cardboard webs places different requirements on the adhesive than gluing foam plastic sheets, i.a. because in the former case it concerns hydrophilic and in the latter case hydrophobic materials. The sticking mechanism in this known case is also based on a structural change in the colloidal system, which is specific to the components, emphasizing that the opposite effect will be achieved by using kaolin instead of "Neuburger" chalk under otherwise similar conditions. The "Neuburger" chalk's suitability for gluing cardboard webs is based on the specific physical structure of this material, as clearly stated in the aforementioned German specification document.
Det var derfor overraskende at ikke bare "Neuburger"-kritt, som dekkes av begrepet "materiale som mineralogisk inneholder mer enn 15% kaolinitt", men også kaolin, som likeledes dekkes av begrepet, egner seg for fremstilling av et klebestoff som er eg-net til klebning av skumplastplater, dvs. av materialer som med hensyn til kjemisk og fysikalsk struktur skiller seg vesentlig It was therefore surprising that not only "Neuburger" chalk, which is covered by the term "material which mineralogically contains more than 15% kaolinite", but also kaolin, which is likewise covered by the term, is suitable for the production of an adhesive which is eg- net for gluing foam plastic sheets, i.e. of materials that differ significantly in terms of chemical and physical structure
fra papp-baner.from cardboard lanes.

Ifolge oppfinnelsen er både naturlig forekommende materialer, som mineralogisk inneholder mer enn 15% kaolinitt og syntetisk fremstilte materialer som mineralogisk inneholder mer enn 15% kaolinitt, dvs. også ren kaolinitt, aktuelle. Da slike materialer forekommer hyppig i naturen, vil det fortrinnsvis benyttes naturlig forekommende produkter. Det vesentlige for slike materialer er at de mineralogisk inneholder mer enn 15% kaolinitt, dvs. har mer enn 15% kaolinitt i gitteret. Kaolitt-gitterstrukturen er f. eks. vist i "Remy, Lehrbuch der anorganischen Chemie", 12. oppi., So 624. According to the invention, both naturally occurring materials which mineralogically contain more than 15% kaolinite and synthetically produced materials which mineralogically contain more than 15% kaolinite, i.e. also pure kaolinite, are relevant. As such materials occur frequently in nature, naturally occurring products will preferably be used. The essential thing for such materials is that they mineralogically contain more than 15% kaolinite, i.e. have more than 15% kaolinite in the lattice. The kaolite lattice structure is e.g. shown in "Remy, Lehrbuch der anorganischen Chemie", 12. oppi., So 624.
Det er videre særdeles overraskende at fremstillingen av klebe-Furthermore, it is particularly surprising that the production of adhesive

stoffene ifolge oppfinnelsen ikke er mulig ved bruk av de struk-turelt svært like silikatene bentonitt (montmorillonitt), talk og glimmer, skjont også disse materialer er nesten identiske med de materialer som er definert ifolge oppfinnelsen, f.eks. med henblikk på deres tiksotropi og andre fysikalske egenskaper som betraktes som vesentlige for klebevirkningen. Det er videre overraskende at bentonitt (montmorillonitt), talk og glimmer ik-ke bare er uegnet for fremstilling av klebestoffene ifolge oppfinnelsen, men dessuten vil oppheve virkningen av f.eks. kaolinitt, hvis de nevnte materialer brukes sammen med kaolinitt, the substances according to the invention is not possible when using the structurally very similar silicates bentonite (montmorillonite), talc and mica, although these materials are also almost identical to the materials defined according to the invention, e.g. with regard to their thixotropy and other physical properties which are considered essential for the adhesive effect. It is also surprising that bentonite (montmorillonite), talc and mica are not only unsuitable for the production of the adhesives according to the invention, but will also negate the effect of e.g. kaolinite, if the aforementioned materials are used together with kaolinite,
selv om kaolinitt foreligger i storre mengder.although kaolinite is present in large quantities.
Fortrinnsvis inneholder klebestoffet ifolge oppfinnelsen 15-50 vekt-%, spesielt 25-45 vekt-% materiale som mineralogisk inneholder mer enn 15% kaolinitt, beregnet av den totale blanding» Preferably, the adhesive according to the invention contains 15-50% by weight, especially 25-45% by weight, of material which mineralogically contains more than 15% kaolinite, calculated from the total mixture"
Alkalisilikatopplbsningen består fortrinnsvis av en natrium-silikatopplosning eller en kaliumsilikatopplosning eller en blanding av disse to opplbsninger. Derved har natriumsilikatopplosningen fortrinnsvis et vektforhold SiO2:Na20 = 2,9-3,7:1 og kaliumsilikatopplbsningen et vektforhold Si02:K2,0 = 2,2-2,7:1. Natriumsilikatopplosningens faststoffinnhold er 25-40 vekt-", fortrinnsvis 32-37 vekt-% og kaliumsilikatopplosningens er 20-32 vekt-%, fortrinnsvis 25-30 vekt-%. The alkali silicate solution preferably consists of a sodium silicate solution or a potassium silicate solution or a mixture of these two solutions. Thereby, the sodium silicate solution preferably has a weight ratio SiO2:Na20 = 2.9-3.7:1 and the potassium silicate solution a weight ratio SiO2:K2.0 = 2.2-2.7:1. The solids content of the sodium silicate solution is 25-40% by weight, preferably 32-37% by weight and that of the potassium silicate solution is 20-32% by weight, preferably 25-30% by weight.
Klebestoffene ifolge oppfinnelsen kan også inneholde tilsetninger som konvensjonelt iblandes klebestoffer på basis av alkalisilikatopplosninger, f.eks. stivelse, nedbrytningsprodukter av stivelse, sukker og alkalifosfater. The adhesives according to the invention can also contain additives that are conventionally mixed with adhesives based on alkali silicate solutions, e.g. starch, breakdown products of starch, sugar and alkaline phosphates.
i i Klebestoffene ifolge oppfinnelsen foreligger i form av påstryk-bare tilberedninger, som uten vanskelighet kan anbringes på ver-tikale flater eller takflater, f.eks. med sparkel. Normalt vil skumplastplåtene som skal klebes, især polystyrolskumplater, gis et belegg på o 500-600 g/m 2 og presses lett mot underlaget. Det vil straks inntre en klebevirkning, slik at platene fastholdes på stedet. Deretter folger fortrinnsvis torking ved værelsestem-peratur under en tidsperiode på caQ 15 timer. Deretter vil klebevirkningen være så sterk at kunststoffplatene, hvis de skal fjer-nes fra underlaget, snarere revner ved siden av klebestedet enn i i The adhesives according to the invention are available in the form of spreadable preparations, which can be placed without difficulty on vertical surfaces or roof surfaces, e.g. with trowel. Normally, the foam plastic sheets to be glued, especially polystyrene foam sheets, will be given a coating of o 500-600 g/m 2 and lightly pressed against the substrate. An adhesive effect will immediately occur, so that the plates are held in place. This is then preferably followed by drying at room temperature for a period of approx. 15 hours. Afterwards, the adhesive effect will be so strong that, if the plastic sheets are to be removed from the substrate, they will rather crack next to the place of adhesion than
at klebeforbindelsen oppheves.that the adhesive connection is cancelled.
Som underlag for klebning av skumpiastplater ved bruk av klebestoff et ifolge oppfinnelsen vil fortrinnsvis underlag av tre eller mineral-materialer komme på tale. As a substrate for gluing foam plaster boards using an adhesive according to the invention, substrates made of wood or mineral materials will preferably be used.
Da folgende eksempler illustrerer oppfinnelsen.As the following examples illustrate the invention.
Eksempel 1Example 1
I 68 % natronvannglassopplosning med et faststoffinnhold på 35,8% dg et vektforhold Si02:Na20 = 3,3:1 innarbeides 32% kaolin, som mineralogisk består av 95% kaolinitt. Det således fremstilte klebestoff kan anbringes på en skumplastplate som skal klebes ved hjelp av sparkel. Når en slik plate presses not et underlag av tre eller på et mineralsk underlag, vil det straks oppstå ad-hesjon, slik at platen holdes på plass. Etter ca. 15 timers torking er det ikke lenger mulig å losne platen uten at denne revner langs klebeforbindelsen. In a 68% soda-water glass solution with a solids content of 35.8% dg a weight ratio Si02:Na20 = 3.3:1, 32% kaolin is incorporated, which mineralogically consists of 95% kaolinite. The adhesive produced in this way can be placed on a foam plastic sheet which is to be glued using a trowel. When such a plate is pressed against a wooden or mineral substrate, adhesion will immediately occur, so that the plate is held in place. After approx. After 15 hours of drying, it is no longer possible to detach the panel without it cracking along the adhesive connection.

Hvis dette klebestoff anbringes på en skumplastplate som skal klebes i en mengde på 500-600 g/m , vil det etter torking oppnås en binding som er så sterk at platen<0>revner ved siden av klebestedet ved et forsok på å losne platen. and a weight ratio of SiO2:Na20 = 3.15:1, 38% "Neuburger" chalk is incorporated, which mineralogically consists of 35% kaolinite and 65% of a silicic acid modification. If this adhesive is placed on a foam plastic sheet to be glued in an amount of 500-600 g/m , after drying, a bond will be achieved which is so strong that the sheet <0>cracks next to the place of adhesion when an attempt is made to loosen the sheet.

og et vektforhold Si02:Na20 = 3,42:1 innarbeides 38% "Neuburger kritt, som mineralogisk består av, 25% kaolinitt og 75% av en kiselsyremodifikasjon. Også i dette tilfelle oppnås samme klebevirkning som ved de ovenfor omtalte eksempler ved påforing av et belegg på 500-600 g/m<2>. and a weight ratio of SiO2:Na20 = 3.42:1, 38% "Neuburg chalk, which mineralogically consists of, 25% kaolinite and 75% of a silicic acid modification, is incorporated. Also in this case, the same adhesive effect is achieved as in the above-mentioned examples by applying a coating of 500-600 g/m<2>.
