Description
Oppfinnelsen vedrører en vandig klebende beleggings-^masse for mineralfiber på basis- av alkalisilikatløsninger,,' ■■ som inneholder finfordelte, uorganiske pulvere. :j- • The invention relates to an aqueous adhesive coating compound for mineral fibers based on alkali silicate solutions containing finely divided inorganic powders. :j- •
I stamsøknaden 782157 er det beskrevet et klebemiddél i! .; og/eller en bekledningsmasse for mineralfiberplatér, på !'-<:,>basis av alkalisilikatløsninger, med innhold av finfor- \ f. j delt uorganisk pulverdg organiske polymerer. Dette har' ' en oppløsning, av ett eller flere alkalisilikater som inne-:'. *| holder ett eller flere mineralogiske stoffer med mer enn 20% kaolinitt, samt en eller flere vannløselige. og alkali-bestandige polymere akrylater, så som metakrylater. In the parent application 782157, an adhesive agent is described in! .; and/or a coating compound for mineral fiber panels, based on alkali silicate solutions, containing finely divided inorganic powder and organic polymers. This has' ' a solution, of one or more alkali silicates which contain-:'. *| holds one or more mineralogical substances with more than 20% kaolinite, as well as one or more water-soluble ones. and alkali-resistant polymeric acrylates, such as methacrylates.
Det ønskes nå et klebemiddél som er særlig egnet for påsprøyting på mineralfibre. What is now wanted is an adhesive that is particularly suitable for spraying on mineral fibres.
Fra tysk offentliggjøringsskrift 2.460.543 er detFrom German publication document 2,460,543 it is
kjent en masse, som enten kan brukes som klebemiddél eller som beskyttelsesmasse på metall eller andre materialer og som består av 60-95 vektsdeler vannglas, 4-16 vektsdeler leirmineralske stoffer, 1-15 vektsdeler oksyder eller karbonater av jordalkaliene eller av sink, oksyder eller hydroksyder av aluminium og/eller bariumsulfåt, samt 0-5 vektsdeler pigmenter. Som leirmineralske stoffer blir det brukt kaolin, talkum eller blandinger av disse. known a mass, which can either be used as an adhesive or as a protective mass on metal or other materials and which consists of 60-95 parts by weight of water glass, 4-16 parts by weight of clay minerals, 1-15 parts by weight of oxides or carbonates of the alkaline earths or of zinc, oxides or hydroxides of aluminum and/or barium sulphate, as well as 0-5 parts by weight of pigments. Kaolin, talc or mixtures of these are used as clay mineral substances.
Ved bruken av de nevnte oksyder, hydroksyder og karbonater blir lagringsevnen til slike masser meget begrens-et. Viskositeten stiger sterkt med lagertidén, idet en slik masse etter 10-15 dager, avhengig av sammensetningen, gelerer. Dessuten er disse masser tilbøyelig til en opp-deling, idet de faste stoffer avsetter seg til pastaaktig masse., slik at de blir vanskelige eller overhodet ikke mulige å få tilbake i sin opprinnelige konsistens. When the aforementioned oxides, hydroxides and carbonates are used, the storage capacity of such masses is very limited. The viscosity increases strongly with storage time, as such a mass gels after 10-15 days, depending on the composition. Moreover, these masses are prone to a breakdown, as the solids settle to 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 A further disadvantage of these known masses exists
—i~aJ:._d_eJL-må._overhol des helt bestemte tørkingsbetin gelser -i~aJ:._d_eJL must._be observed completely specific drying conditions
samt en helt bestemt tørkingsgrad, for å hindre at klebe-steder eller belegginger blir sprø. as well as a completely specific degree of drying, to prevent sticking points or coatings from becoming brittle.
Sprøyteisoleringen av f.eks. kraftverkturbiner med asbest er kjent fra tidligere. Ved denne framgangsmåten blir findelte asbestfibre blåst med luft mot den apparat-del som skal isoleres og samtidig bundet med pådynket vani. Et særlig klebemiddél ble imidlertid ikke brukt for denne framgangsmåte. Bearbeidelsen av asbestfibre forutsetter imidlertid en høy andel asbeststøv på arbeidsstedet, som utgjør en betydelig sunnhetsrisiko (asbestose). Derfor blir det allerede i lang tid forsøkt, istedenfor asbest, The spray insulation of e.g. power plant turbines with asbestos are 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 wool. 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 poses a significant health risk (asbestosis). Therefore, attempts have already been made for a long time, instead of asbestos,
å bruke mineralfibre for dette formål. Behandlingen av mineralfibre uten bindemiddel er imidlertid ikke mulig.. to use mineral fibers for this purpose. However, the processing of mineral fibers without a binder is not possible.
Et klebemiddél for sprøyteisolering ved bruk av mineralfibre må tilfredsstille følgende krav: a) Klebemidlet må henge godt fast i begynnelsen, for at det påsprøytete isolasjonssjikt ikke skal falle av. An adhesive for spray insulation using mineral fibers must satisfy the following requirements: 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 iso-las j onssj iktet. 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, The adhesives for mineral fibers that are known up to now,
har ikke vært tilfredsstillende etter disse kriterier.has not been satisfactory according to these criteria.
Det er også blitt forsøkt, å blande mineralfibre med sement og binde den ved blåsingen av blandingen mot den gjenstand som skal isoleres ved påsprøyting av vann. Denns framgangsmåte har den ulempe, at det på arbeidsstedet danner seg en betydelig sementkonsentrasjon, som vanskelig-gjør behandlingen betydelig og som krever omfattende sikkerhets-forholdsregler. Attempts have also been made to mix mineral fibers with cement and bind it by blowing the mixture against the object to be insulated by spraying water. Its procedure has the disadvantage that a significant concentration of cement forms at the workplace, which makes the treatment considerably more difficult and which requires extensive safety precautions.
Klebemidlet ifølge den foretrukne utførelsesform som er beskrevet ovenfor oppfyller ikke bare alle krav som blir stilt til et klebemiddél for sprøyteisoler ing ved bruk av mineralfibre, men virker i tillegg dessuten som korrosjonsbeskyttelse på metaller. The adhesive according to the preferred embodiment described above not only fulfills all requirements for an adhesive for spray insulation using mineral fibres, but also acts as corrosion protection on metals.

Sammensetningen ifølge oppfinnelsen består av de be-standdeler som er angitt i patentkrav 1. The composition according to the invention consists of the ingredients specified in patent claim 1.
Det er særlig fordelaktig å la sammensetningen inneholde opptil 5 vekti findelt hydrert siliciumoksyd (kisel- I syre). It is particularly advantageous to allow the composition to contain up to 5% by weight of finely divided hydrated silicon oxide (silicic acid).
Fortrinnsvis inneholder sammensetningen et vannløseli?silikonprodukt, særlig et alkalisalt av metylkiselsyre og/eller et aluminiumsalt av en rettkjedet alifatisk kar- • '■ bonsyre med 16t26 karbonatomer, for økning av hydrofobiéh -i og dermedVannbestandigheten. Preferably, the composition contains a water-soluble silicone product, in particular an alkali salt of methyl silicic acid and/or an aluminum salt of a straight-chain aliphatic carboxylic acid with 16 to 26 carbon atoms, to increase hydrophobicity and thus water resistance.
Ifølge en ytterligere foretrukket u.tførelsesform inneholder sammensetningen et alkalialuminåt, særlig natrium-og kaliumaluminat, fordi et slikt alkalialuminåt over len-' ger tidsrom danner vannløselige : alkalisilikatér, som for ligger i findelt form og som bidrar til vannbestandig-heten. Dessuten øker de tilsatte alkalialuminater viskositeten, slik at det bidrar til å forhindre en pigmentav-leiring. Dessuten oppnås ved denne tilsetning en tikso-tropeffekt. According to a further preferred embodiment, the composition contains an alkali aluminate, in particular sodium and potassium aluminate, because such an alkali aluminate forms water-soluble alkali silicates over a longer period of time, which are in finely divided form and which contribute to the water resistance. Moreover, the added alkali aluminates increase the viscosity, so that it helps to prevent a pigment deposit. In addition, a thixotropic effect is achieved with this addition.
Fortrinnsvis består den anvendte alkalisilikatløsning av en natriumsilikatløsning, kaliumsilikatløsning eller av en blanding av disse løsninger. I det siste tilfellet blir det oppnådd særlig fleksible overtrekk hhv,klebe fuger. 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.
Fortrinnsvis oppviser natriumsilikatløsningen et vektforhold SiO : Na20 på 2,5 til 3,8:1 og kaliumsilikatløs-ningen et vektforhold SiO : K20 på 1,6-2,7:1. Innholdet av fast stoff i natriumsilikatløsningen utgjør fortrinnsvis 28-42 , særlig 34-:38 vekti og inneholdet i kaliumsili-katløsningeri 24-44, særlig 35-41 vekti. Preferably, the sodium silicate solution exhibits a weight ratio SiO:Na20 of 2.5 to 3.8:1 and the potassium silicate solution a weight ratio SiO: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 potassium silicate solutions is 24-44, especially 35-41 by weight.
Fortrinnsvis inneholder sammensetningen en blanding . av 98 til 50 vekti, særlig 96 til 90 vekti av en natrium-silikatløsning og 2 til 50 vekti, særlig 4 til 10 vekti, av en kaliumsilikatløsning. Preferably, the composition contains a mixture. of 98 to 50 by weight, especially 96 to 90 by weight of a sodium silicate solution and 2 to 50 by weight, especially 4 to 10 by weight, of a potassium silicate solution.
Innholdet av pulvermater iale,. hvorav mer enn 15 vekti, fortrinnsvis mer enn 201 av mineralinnholdét, er fordelaktig 1-10 vekti, fortrinnsvis 2-6 vekti. Vekti i denne sammenheng blir regnet av den totale sammensetning. Inn holdet av alkalimetallaluminat utgjør fordelaktig opptil .1.0 vekti fortrinnsvis 1-5 vekti. Silikon/produktet foreligger fortrinnsvis i en mengde på 0,1-10 vekti, og særlig i en mengde på 0,5-3 vekti. Det dreier seg særlig om et alkalisalt. til metylkiselsyre. Innholdet av aluminiumsaltet til en rettkjedet alifatisk karbonsyre med 12 til 26 karbonatomer utgjør fortrinnsvis 0,05. til 5 vekti og særlig 0,01 til 1 vekti. The content of powdered materials, . of which more than 15 by weight, preferably more than 201 of the mineral content, is advantageously 1-10 by weight, preferably 2-6 by weight. Weight in this context is calculated from the total composition. The content of alkali metal aluminate advantageously amounts to up to .1.0 by weight, preferably 1-5 by weight. The silicone/product is preferably present in an amount of 0.1-10 by weight, and particularly in an amount of 0.5-3 by weight. This is particularly the case with an alkali salt. to methylsilicic acid. The content of the aluminum salt of a straight-chain aliphatic carboxylic acid with 12 to 26 carbon atoms is preferably 0.05. to 5 by weight and especially 0.01 to 1 by weight.
Dessuten kan sammensetningen ifølge oppfinnelsen inneholde opptil 1 vekti, f.eks. 0,1 til 1 vektig at er poly-mert ammonium- eller natriumpolyakrylat som pigmentfor- • deler, særlig for fordeling av jernoksydpigmenter, samt av aluminiumsaltene til de nevnte rettkjedete alifatiske karbonsyrer. In addition, the composition according to the invention can contain up to 1 by weight, e.g. 0.1 to 1 by weight of polymerized 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 vekti, eksempelvis 0,1 til 3. vekti 1itiumhydrok-syd for økning av vannbestandigh,éten, Furthermore, the composition can preferably contain up to 3% by weight, for example 0.1 to 3% by weight of lithium hydroxide to increase water resistance,
Dessuten kan det tilsettes opptil 4 vekti alkalisbe-standige fargepigmenter. In addition, up to 4% by weight of alkali-resistant color pigments can be added.
For å øke fleksibiliteten til klébefugene hhv. belegg-ene, kan det dessuten fortrinnsvis tilsettes opptil 5 vekti, særlig 0,5 til 2 vekti, flerverdige alkoholer. To increase the flexibility of the adhesive joints or the coatings, it may also preferably be added up to 5 by weight, in particular 0.5 to 2 by weight, of polyhydric alcohols.
Tilsetningen av en mikrokrystallisk poletylen- eller polypropylenvoks, særlig i en mengde på 0,1 til 3 vekti, særlig for^delaktig i en mengde på 0,3 til 1,5 vekti, 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 3 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 tilsetnings-midler, slik at de tilsettqs på vanlig måte til klebemidler på alkalisilikatbasis, særlig alkalifosfatér, fortrinnsvis trinatriumf orsf at, eller et'.eller flere sukkere . Additives can also be added to the compositions, so that they 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.
