Sdisse masser tilbøyelig til en oppdeling, idet de faste stoffe:-avsetter seg til en pastaaktig masse, slik at de blir vanskelige eller overhode.t ikke mulige å få tilbake i sin opprinnelige konsistens. These masses are prone to a division, as the solids:-deposit into a paste-like mass, so that they become difficult or not at all possible to get back to their original consistency.
En ytterligere ulempe ved disse kjente masser består i atA further disadvantage of these known masses consists in that
det må overholdes helt bestemte tørkingsbetingelser samt en helt bestemt tørkingsgrad, for å hindre at klebesteder eller belegginger blir sprø. very specific drying conditions must be observed as well as a very specific degree of drying, to prevent adhesive points or coatings from becoming brittle.

oppfinnelsen brukes som isolasjonsmaterialer: samt som klebe" middel for metalliske eller ikke-metalliske materialer, the invention is used as insulating materials: as well as as an adhesive for metallic or non-metallic materials,
Sammensetningene ifølge oppfinnelsen utmerker seg. ved en meget god lagringsstabilitet. I lukkete beholdere kan de lagres i minst 12 måneder uten kvalitetsreduksjon. En forstyrrende av-setning eller fastklebing av de faste stoffene opptrer ikke. The compositions according to the invention excel. with a very good storage stability. In closed containers, they can be stored for at least 12 months without quality reduction. Disturbing deposition or sticking of the solids does not occur.
En skal også fremheve det forhold, at det uavhengig av tørkegraden og tørkingsbetingelsene blir oppnådd klebesteder henholdsvis belegginger som ikke blir sprø. Dessuten har de oppnådde klebesteder henholdsvis belegginger en høy bestandig-het mot vann, noe som er en betydelig fordel i mange sammen-henger. One must also highlight the fact that, regardless of the degree of drying and the drying conditions, adhesive points or coatings that do not become brittle are achieved. In addition, the adhesive points and coatings obtained have a high resistance to water, which is a significant advantage in many contexts.
Fortrinnsvis inneholder sammensetningene ifølge oppfinnelsen et vannløselig silikonprodukt, særlig et alkalisalt av metylkiselsyre og/eller et aluminiumssalt av en rettkjedet alifatisk karbonsyre med 16-26. karbonatomer, for økning av hydrofobien og dermed vannbestandigheten. Preferably, the compositions according to the invention contain a water-soluble silicone product, in particular an alkali salt of methylsilicic acid and/or an aluminum salt of a straight-chain aliphatic carboxylic acid with 16-26. carbon atoms, to increase the hydrophobicity and thus the water resistance.
Ifølge en.ytterligere foretrukket utførelsesform inneholder sammensetningen et alkalialuminat, særlig natrium- According to a further preferred embodiment, the composition contains an alkali aluminate, in particular sodium
og kaliumaluminat, fordi et slikt alkalialuminat over lenger tidsrom danner vannuløselige alkalisilikater, som foreligger i fordelt form og bidrar til vannbestandigheten. Dessuten øker de tilsatte alkalialuminater viskositeten, slik at det bidrar til å forhindre en pigmentavleiring. Dessuten oppnås ved denne tilsetning en tixotropeffekt. and potassium aluminate, because such an alkali aluminate forms water-insoluble alkali silicates over a longer period of time, which exist in distributed form and contribute to water resistance. In addition, the added alkali aluminates increase the viscosity, so that it helps to prevent a pigment deposit. In addition, a thixotropic effect is achieved by this addition.
Fortrinnvis består den anvendte alkalisili-katløsning av en natriumsilikatløsning, kaliumsilikatløsning eller av en blanding av disse løsninger. I det siste tilfellet blir det oppnådd særlig fleksible overtrekk henholdsvis klebefuger. Preferably, the alkali silicate solution used consists of a sodium silicate solution, potassium silicate solution or a mixture of these solutions. In the latter case, particularly flexible covers or adhesive joints are achieved.
Fortrinnvis oppviser natriumsilikatløsningen et vektsforhold Si02: Na20 på 2.5 til 3.8:1 og kaliumsilikatløsningen et vektsforhold Si02: K20 på 1.6-2.7:1..Innholdet av fast stoff i natriumsilikatløsningen utgjør fortrinnsvis 28-42, særlig 34-38 vekts! og inneholdet i kaliumsilikatløsningen 24-44, særlig 35-41 vekts!. Preferably, the sodium silicate solution exhibits a weight ratio Si02: Na20 of 2.5 to 3.8:1 and the potassium silicate solution a weight ratio Si02: K20 of 1.6-2.7:1.. The content of solids in the sodium silicate solution is preferably 28-42, especially 34-38 by weight! and the content in the potassium silicate solution 24-44, especially 35-41 by weight.
Fortrinnsvis inneholder sammensetningen en blanding avPreferably, the composition contains a mixture of
98 til 50 vekts!, særlig 96 til 90 vekts! av en natriumsilikat-løsning og 2 til 50 vekts!, særlig 4 til 10 vekts!, av en kaliumsilikatløsning. 98 to 50 weight!, especially 96 to 90 weight! of a sodium silicate solution and 2 to 50 by weight, especially 4 to 10 by weight, of a potassium silicate solution.
Fortrinnsvis inneholder sammensetningen en- 5 til 15! vandig alkalisk løsning av.den organiske polymere, særlig en polymer metakrylat, i en mengde på l'.til 20 vekts!, særlig 3 til 12vekts!. Preferably, the composition contains a- 5 to 15! aqueous alkaline solution of the organic polymer, in particular a polymeric methacrylate, in an amount of 1 to 20 by weight, especially 3 to 12 by weight.
Innholdet av det mineralogiske materiale som inneholder mer enn 20! kaolinitt, utgjør 5 til 45 vekts!, særlig 7 til 20 vekts!, idet disse vekts!-tall er henført til totalsammen-setningen.. The content of the mineralogical material containing more than 20! kaolinite, amounts to 5 to 45 by weight, especially 7 to 20 by weight, as these weight figures are attributed to the total composition.
Innholdet av alkalialuminat utgjør fortrinnsvis opptil lOvekts!, særlig 1 til 5 vekts!. The content of alkali aluminate is preferably up to 10% by weight, in particular 1 to 5% by weight.
Silikonproduktet foreligger fortrinnsvis i en mengde på 0.1-10 vekts!, og særlig i en mengde på 0.5-3 vekts!. Det dreier seg særlig om et alkalisalt til metylkiselsyre. Innholdet av aluminiumssaltet til en rettkjedet alifatisk karbonsyre med 12 til 26 karbonatomer utgjør fortrinnsvis 0.05 til 5 vekts! og særlig 0.01 til 1 vekts!. The silicone product is preferably present in an amount of 0.1-10 by weight, and especially in an amount of 0.5-3 by weight. This is particularly the case with an alkali salt of methylsilicic acid. The content of the aluminum salt of a straight-chain aliphatic carboxylic acid with 12 to 26 carbon atoms preferably amounts to 0.05 to 5 wt. and especially 0.01 to 1 wt.!.
Dessuten kan sammensetningen ifølge oppfinnelsen inneholde opptil 1 vekts!, for eksempel 0.1 til 1 vekts!, av et polymert ammonium- eller natriumpolyakrylat'som pigmentfordeler, særlig for fordeling av jernoksydpigmenter, samt av aluminiumssaltene til de nevnte rettkjedete alifatiske karbonsyrer. Furthermore, the composition according to the invention can contain up to 1 wt., for example 0.1 to 1 wt., of a polymeric ammonium or sodium polyacrylate as a pigment distributor, particularly for the distribution of iron oxide pigments, as well as of the aluminum salts of the aforementioned straight-chain aliphatic carboxylic acids.
Dessuten kan sammensetningen fortrinnsvis inneholde opptil 3 vekts!, eksempelvis 0.1 til 3vekts! litiumhydroksyd for økning av vannbestandigheten- Furthermore, the composition can preferably contain up to 3 wt.!, for example 0.1 to 3 wt.! lithium hydroxide to increase the water resistance
Dessuten kan det tilsettes opptil 4 vekts! alkalibestandige fargepigmenter. In addition, up to 4 weights can be added! alkali-resistant color pigments.
For å øke fleksibiliteten til klebefugene henholdsvis beleggene, kan det dessuten fortrinnsvis tilsettes opptil 5 vekts!, særlig 0.5 til 2 vekts!, flerverdige alkoholer. In order to increase the flexibility of the adhesive joints or the coatings, up to 5 wt.%, in particular 0.5 to 2 wt.%, of polyhydric alcohols can also preferably be added.
Tilsetningen av en mikrokrystallisk polyetylen- eller polypropylenvoks, særlig i en mengde på 0.1 til 4 vekts!, særlig fordelaktig i en mengde på 0.3 til 1.5 vekts!, har likeledes vist seg hensiktsmessig for å øke hydrofobien. The addition of a microcrystalline polyethylene or polypropylene wax, in particular in an amount of 0.1 to 4 by weight, particularly advantageously in an amount of 0.3 to 1.5 by weight, has likewise proved appropriate for increasing the hydrophobicity.
Dessuten kan sammensetningene tilsettes tilsetningsmidler, slik som de tilsettes på vanlig måte til klebemidler på alkalisilikatbasis, særlig alkalifpsfater, fortrinnsvis trinatriumfosfat, eller et eller flere sukkere. Additives can also be added to the compositions, such as are added in the usual way to adhesives on an alkali silicate basis, in particular alkali phosphates, preferably trisodium phosphate, or one or more sugars.
Ifølge en ytterligere foretrukket utførelsesform blirAccording to a further preferred embodiment,
det ifølge oppfinnelsen laget et klebemiddel for en såkalt the invention made an adhesive for a so-called
"sprøytemasseisolering", som er kjennetegnet ved eri løsning av en eller flere alkalisilikater med et innhold av 1 til 10 vekts!, særlig 2 til 6 vekts!, av en eller flere mineralo- "spray mass insulation", which is characterized by a solution of one or more alkali silicates with a content of 1 to 10 by weight, especially 2 to 6 by weight, of one or more minerals

Sprøyteisoleringen av for eksempel kraftverkturbinerThe spray insulation of, for example, power plant turbines
med asbest er kjent fra tidligere. Ved denne framgangsmåten blir findelte asbestfibre blåst^med luft mot den apparatdel som skal isoleres og.samtidig bundet med pådynket vann. Et særlig klebemiddel ble imidlertid ikke brukt for denne framgangsmåte. Bearbeidelsen av asbestfibre forutsetter imidlertid en høy andel asbeststøv på arbeidsstedet, som utgjør en be- with asbestos is known from the past. In this procedure, finely divided asbestos fibers are blown with air towards the appliance part to be insulated and at the same time bound with soaked water. However, a special adhesive was not used for this procedure. However, the processing of asbestos fibers requires a high proportion of asbestos dust at the workplace, which constitutes a
tydelig sunnhetsrisiko (asbestose)-. Derfor blir det allerede i lang tid- forsøkt, istedenfor asbest( å bruke mineralfibre for dette formål. Behandling av mineralfibre uten bindemiddel er imidlertid ikke mulig. clear health risk (asbestosis)-. Therefore, attempts have already been made for a long time to use mineral fibers instead of asbestos for this purpose. Treatment of mineral fibers without a binder is not possible, however.
Et klebemiddel for sprøyteisolering ved bruk av mineral-An adhesive for spray insulation using mineral
fibre må tilfredsstille følgende krav:fibers must meet the following requirements:
a) Klebemidlet må henge godt fast i begynnelsen, for at det påsprøytete isolasjonssjikt ikke skal falle av. a) The adhesive must adhere firmly at the beginning, so that the sprayed-on insulation layer does not fall off.
b) Klebemidlet må tåle minst 1000° C.b) The adhesive must withstand at least 1000° C.
c) Klebemidlet skal ikke, dryppe ut eller renne ut av isola-sjonssjiktet. c) The adhesive must not drip or flow out of the insulation layer.
d) Klebemidlet må være lagringsdyktig over lenger tid.d) The adhesive must be storable over a longer period of time.
e) Klebemidlet må ikke virke korrosivt på metaller.e) The adhesive must not be corrosive to metals.
De klebemidler for mineralfibre som hittil er kjent, harThe adhesives for mineral fibers that have been known to date have
ikke vært tilfredsstillende etter disse kriterier.not been satisfactory according to these criteria.
Det er også blitt forsøkt, å blande mineralfibre med sementAttempts have also been made to mix mineral fibers with cement
og binde den ved blåsingen av blandingen mot den gjenstand som skal isoleres ved påsprøyting av vann. Denne framgangsmåte har den ulempe, at det på arbeidsstedet danner seg en betydelig sementstøvkonsentrasjon, som vanskeliggjør behandlingen betyde- and bind it by blowing the mixture against the object to be insulated by spraying water. This procedure has the disadvantage that a significant concentration of cement dust forms at the workplace, which significantly complicates the treatment.
