FyllmiddelFiller
Foreliggende oppfinnelse vedrører et fyllmiddel eller fyllstoff egnet for slike produkter som i det minste delvis er opp-bygget av organisk materiale. Det kan her dreie som om ferdige produkter egnet for umiddelbar anvendelse eller for mellomprodukter (halvfabrikata) som trenger ytterligere bearbeiding. The present invention relates to a filler or filler suitable for such products which are at least partly made up of organic material. Here it can be about whether finished products are suitable for immediate use or for intermediate products (semi-finished products) that need further processing.
I første rekke dreier det seg om plast-, gummi-, petroleum-In the first place, it concerns plastic, rubber, petroleum
og likartede produkter, selv om fyllstoffet ifølge oppfinnelsen også kan finne anvendelse i annen sammenheng, hvilket vil fremgå av den etterfølgende beskrivelse. and similar products, although the filler according to the invention can also find use in other contexts, which will be apparent from the following description.
En primær hensikt med oppfinnelsen er å tilveiebringe et fyllstoff som kan ibTandes i det aktuelle produkt i langt større grad, dvs. i en høyere prosentandel enn det som er mulig med kjente fyllstoffer, under bibeholdelse av god bruddstyrke eller styrkeegenskaper. Dette oppnås ifølge op<p>finnelsen hvis fyllstoffet utgjøres av et i og for seg kjent kalsiumhydrosili-katmateriale inneholdende betydelige andeler krystallvann, hvilket materiale finfordeles til partikler som har en maksimal størrelse på 90 pm, ved at materialet fremstilles under anvendelse av et vannoverskudd og hvor materialet får en åpen mikro-porestruktur som gir ekstremt god sammenheftning med det organiske materialet. Tidligere kjente fyllstoffer vil i praksis kun virke utfyllende i det aktuelle produkt, mens bind-ingene i det vesentlige ble besørget av andre bestanddeler i produktet. Dette medfører naturligvis at fyllstoffinnbland-ingen må holdes på et begrenset nivå da det ellers oppstår fare for disintegrering av bestanddelene. A primary purpose of the invention is to provide a filler which can be incorporated into the product in question to a far greater extent, i.e. in a higher percentage than is possible with known fillers, while maintaining good breaking strength or strength properties. This is achieved according to the invention if the filler consists of a known per se calcium hydrosilicate material containing significant proportions of crystal water, which material is finely divided into particles having a maximum size of 90 pm, by the material being produced using an excess of water and where the material gets an open micro-pore structure that gives extremely good cohesion with the organic material. Previously known fillers will in practice only have a complementary effect in the product in question, while the bindings were essentially provided by other components in the product. This naturally means that the filler admixture must be kept to a limited level, otherwise there is a risk of disintegration of the components.
I motsetning til dette tilveiebringer oppfinnelsen et fyllstoff hvis partikler har en uregelmessig, mikro<p>orøs struktur som be-fordrer en salgs mekanisk låsning som gir en meget god binding Ltil bindemiddelmaterialet. Herved kan andelen av fyllstoff ...i økes i overraskende stor grad under bibeholdelse av konstante eller til og med bedre bruddstyrke. In contrast, the invention provides a filler whose particles have an irregular, micro<p>orous structure which promotes a good mechanical locking which gives a very good bond L to the binder material. In this way, the proportion of filler ...in can be increased to a surprisingly large extent while maintaining constant or even better breaking strength.
Et i praksis meget egnet fyllstoff i henhold til oppfinnelsen utgjøres av malt gassbetong. Vanlig gassbetong utgjøres kjemisk av kalsiumsilikathydrater som er bibrakt porøsitet ved hjelp av et passende esemiddel. Vanligvis fremstilles gassbetong av en grunnblanding-inneholdende sand (gir hvit gassbetong) eller skiferaske (gir blågrå gassbetong) som kiselsyre-holdig materiale, samt kalk og/eller sement som hydraulisk bindemiddel, og hvor grunnblandingen delvis tilsettes vann og delvis■ aluminiumpulver som esemiddel. Etter esing oppdeles og formes gassbetongen på ønsket måte, hvoretter den dampherdes under forhøyet trykk og forhøyet temperatur og på denne måte oppnås et porøst, uorganisk produkt med en volumvekt som vanligvis går opp til 0,4-0,65 kg/dm . A practically very suitable filler according to the invention consists of ground aerated concrete. Normal aerated concrete is chemically made up of calcium silicate hydrates which have been given porosity by means of a suitable foaming agent. Generally, aerated concrete is produced from a base mix containing sand (yields white aerated concrete) or shale ash (yields blue-grey aerated concrete) as silicic acid-containing material, as well as lime and/or cement as hydraulic binder, and where the base mix is partly added with water and partly ■ aluminum powder as a blowing agent. After setting, the aerated concrete is divided and shaped in the desired way, after which it is steam-cured under elevated pressure and elevated temperature and in this way a porous, inorganic product is obtained with a volume weight that usually goes up to 0.4-0.65 kg/dm.
Nedenfor er vist et eksempel på sammensetningen av en gassbe-tongtype som er egnet for oppfinnelsens formål. Denne gassbetong fremstilles i praksis under betegnelsen hvit "YTONG". Sammensetningen representeres av en silikatanalyse ifølge tabellen til venstre og en sporelementanalyse ifølge den høyre tabell. Below is shown an example of the composition of an aerated concrete type that is suitable for the purpose of the invention. This aerated concrete is produced in practice under the name white "YTONG". The composition is represented by a silicate analysis according to the table on the left and a trace element analysis according to the right table.
Produktet inneholder ikke spor av asbestfibere og et ubrenn-bart. The product does not contain traces of asbestos fibers and is non-combustible.
Den eksemplifiserte gassbetong har en spesifikk overflate på 23 m<2>/g. Gassbetong med betegnelsen blå "YTONG" 144 og blå "YTONG 195" har spesifikke overflater på henholdsvis '42 m 2/g og 38 m 2/g. Disse høye verdier for den spesifikke overflate forklares av at gassbetongen i tillegg til mikroporene som oppnås ved hjelp av esemidlet også inneholder mikroporer hvilke tilskrives de dannede kalsiumhydrosilikatene. The exemplified aerated concrete has a specific surface area of 23 m<2>/g. Aerated concrete with the designation blue "YTONG" 144 and blue "YTONG 195" has specific surfaces of '42 m 2/g and 38 m 2/g respectively. These high values for the specific surface are explained by the fact that the aerated concrete, in addition to the micropores obtained with the aid of the foaming agent, also contains micropores which are attributed to the formed calcium hydrosilicates.
Utførte forsøk har nå overraskende vist at gassbetong i det alt vesentlige bibeholder sin store spesifikke overflate selv ved fin-fordeling av materiale til fraksjoner langt under 1 mm. Ved disse forsøk ble det anvendt to forskjellige, melliknende fraksjoner av finmalt hvit "YTONG", nemlig en første fraksjon med maksimal partikkelstørrelse <90 pm og en andre fraksjon med en maksimal partikkelstørrelse<20 pm. Tests carried out have now surprisingly shown that aerated concrete essentially retains its large specific surface even when the material is finely divided into fractions well below 1 mm. In these experiments, two different flour-like fractions of finely ground white "YTONG" were used, namely a first fraction with a maximum particle size <90 pm and a second fraction with a maximum particle size <20 pm.

de forskjellige partiklene innblandet i polyetylenplastmasse i andeler på 60-80 vekt-%, hvorved det eksempelvis ved eks-trudering ble erholdt seige, plateformede prøvestykker med god styrke. Til og med ved fyllmiddeltilsetninger overstigende 80 vekt-% av den totale materialemengde ble det erholdt godt sammenhengende prøvestykker som tilnærmet hadde et metallisk utseende. Selv i PVC-plast har innblanding av gassbetongpar-tikler gitt gode resultater. the various particles mixed in polyethylene plastic mass in proportions of 60-80% by weight, whereby tough, plate-shaped test pieces with good strength were obtained, for example by extrusion. Even with filler additions exceeding 80% by weight of the total amount of material, well-connected test pieces were obtained which had an almost metallic appearance. Even in PVC plastic, mixing in aerated concrete particles has given good results.
Ifølge oppfinnelsen kan det knuste og/eller finmalte kalsium-hydrosilikatmateriale ikke bare tjene som fyllstoff i den snev-rere betydning, men også som bærer for ett eller flere, passende aktive tilsetningsmidler for det produkt i hvilket materialet skal inngå. Det kan i dette tilfellet dreie som om tilsetningsmidler så som esemiddel for poredannelse i slutt- og mellomprodukter, peroksyder som herdemiddel, aktivatorer av forskjellige slag, korrosjonsinhibierende bestanddeler, brann-dempende bestanddeler etc. Denne tilsatsmiddelbærende funk-sjon kan oppnås ved at det aktuelle tilsetningsmiddel blandes mekanisk med kalsiumhydrosilikatmaterialer etter at dette er fremstilt,.eventuelt kompletteres med en bindemiddelbehand-ling for tilsetningsmidlets bibeholdelse på eller i material-kornet og/eller partiklene. Det er imidlertid også tenkbart å binde tilsetningsmidlet til kalsiumhydrosilikatmaterialet allerede i forbindelse med dets fremstilling, nemlig ved å la tilsetningsmidlet inngå i den sats av komponenter som er nød-vendig for kalsiumhydrosilikatmaterialets fremstilling. På denne måte er det ytterligere visse muligheter for å variere kalsiumhydrosilikatmaterialets sammensetning innen vide gren-ser, slik at et eller flere av bestanddelene som konvensjonelt According to the invention, the crushed and/or finely ground calcium hydrosilicate material can not only serve as a filler in the narrower sense, but also as a carrier for one or more suitable active additives for the product in which the material is to be included. In this case, it could be additives such as foaming agents for pore formation in final and intermediate products, peroxides as curing agents, activators of various kinds, corrosion-inhibiting components, fire-suppressing components, etc. This additive-carrying function can be achieved by the additive in question mixed mechanically with calcium hydrosilicate materials after this has been produced, optionally supplemented with a binder treatment for the additive's retention on or in the material grain and/or the particles. However, it is also conceivable to bind the additive to the calcium hydrosilicate material already in connection with its production, namely by allowing the additive to be included in the batch of components that are necessary for the production of the calcium hydrosilicate material. In this way, there are further certain possibilities for varying the composition of the calcium hydrosilicate material within wide limits, so that one or more of the components that conventionally

anses som nødvendig for gassbetongproduksjon går ut av sammensetningen, mens det i steden tilføres en eller flere bestanddeler som har selektiv interesse i forbindelse med et visst produkt i hvilket fyllstoffet skal inngå. considered necessary for aerated concrete production leaves the composition, while instead one or more constituents are added which have selective interest in connection with a certain product in which the filler is to be included.
Også ytterlige er det tenkelig å modifisere fyllstoffet i henhold til oppfinnelsen, således kan de ved knusning og/eller malning erholdte korn henholdsvis partikler hydrofoberes i den I hensikt på i og for seg kjent måte nedsette materialets affini-j- tet til vann. På denne måte forbedres bl.a. mulighetene for å lagre materialet. Ytterligere forbedres i særlig grad de fine partiklenes evne til å renne eller med andre ord: deres tendens til å klumpe seg sammen reduseres til et minimum eller elimineres fullstendig. Hydrofobering kan med fordel gjennom-føres ved hjelp av forskjellige typer silikoner og av disse kan eksempelvis et preparat med betegnelsen "Transilan" opp-løst i etylalkohol med overflateaktive tilsetninger anvendes og preparatet kan fortynnes med 5 og enda opptil 100 deler vann før påføring. Dette preparat har god alkaliresistens sammen med god langtidseffekt. Passende skjer påføringen ved besprøyt-ning. Eksempler på andre anvendbare silikoner er eksempelvis organofunksjonelle silaner. Furthermore, it is conceivable to modify the filler according to the invention, thus the grains or particles obtained by crushing and/or grinding can be hydrophobized for the purpose of reducing the material's affinity for water in a manner known per se. In this way, e.g. the possibilities of storing the material. Furthermore, the ability of the fine particles to flow is particularly improved, or in other words: their tendency to clump together is reduced to a minimum or completely eliminated. Hydrophobization can advantageously be carried out using different types of silicones and of these, for example, a preparation with the name "Transilan" dissolved in ethyl alcohol with surface-active additives can be used and the preparation can be diluted with 5 and even up to 100 parts of water before application. This preparation has good alkali resistance together with a good long-term effect. Suitably, the application takes place by spraying. Examples of other applicable silicones are, for example, organofunctional silanes.
Ytterliger kan fyllstoffmaterialet kompletteres med varierende mengder Sb20^/Fe20^, MoO^og MgCO^for forskjellige formål. Furthermore, the filler material can be supplemented with varying amounts of Sb20^/Fe20^, MoO^ and MgCO^ for different purposes.
Fyllstoffet i henhold til oppfinnelsen kan anvendes i en rekke<p>rodukter som har det felles trekk at de innbefatter minst ett organisk bindemiddel. Trolig det mest interessante i denne forbindelse er anvendelse i plaster av forskjellige slag, enten det dreier seg om herde- eller termoplaster. Fyllstoffet ifølge oppfinnelsen foreligger i de temmelig fine fraksjoner på opptil 90 um. Disse fraksjoner er fordelaktige ved at partiklene ren-ner lett og lar seg lett blande i de aktuelle bindemiddelkompo-nenter. De samme fine fraksjoner av fyllstoffet ifølge oppfinnelsen kan også blandes i: The filler according to the invention can be used in a number of products which have the common feature that they include at least one organic binder. Probably the most interesting thing in this connection is the application in plastics of various kinds, whether it concerns thermosetting or thermoplastics. The filler according to the invention is present in the rather fine fractions of up to 90 µm. These fractions are advantageous in that the particles are easy to clean and can be easily mixed in the relevant binder components. The same fine fractions of the filler according to the invention can also be mixed in:
a) gummi i form av såvel naturgummi som syntetisk gummi,a) rubber in the form of both natural rubber and synthetic rubber,
b) farge-, lakk eller lignende overflatebehandlingsprodukter, b) colour, varnish or similar surface treatment products,
c) lim-, klister- eller lignende adhesjonsmiddelprodukter,c) glue, adhesive or similar adhesive products,
d) papp- eller papirprodukter, eksempelvis tapeter,d) cardboard or paper products, for example wallpaper,
e) fiber- og/eller sponprodukter, eksempelvis trefiberplater, e) fiber and/or chip products, for example wood fiber boards,
f) petroleumprodukter eksempelvis asfalt, ogf) petroleum products, for example asphalt, and
g) kombinasjoner av disse.g) combinations of these.
Fordelen med fyllstoffet ifølge oppfinnelsen innen de ovenfor The advantage of the filler according to the invention within the above
oppregnede anvendelsesområder er at de ved siden av og tillate j en høy innblanding (med tilhørende god fremstilningsøkonomi) , enumerated areas of application are that, in addition to and allow j a high mixing (with associated good manufacturing economy),
så kan de som følge av sitt innhold av kjemisk bundet vann ' then, as a result of their content of chemically bound water, they can
(5-8%) utnyttes for å gjøre produktene brann- og flammebestand-ige. Ytterligere virker fyllstoffet korrosjonshemmende idet det er alkalisk og nøytraliserer syrer. (5-8%) is used to make the products fire and flame resistant. Furthermore, the filler acts as a corrosion inhibitor as it is alkaline and neutralizes acids.
Selv om oppfinnelsen er beskrevet i forbindelse med kun en gassbetong eller gassbetonglignende emne så som kalsiumhydrosili-katmateriale er det åpenbart at også andre materialer kan komme på tale. Det vesentlige er således den kombinasjon at mat-erialetes korn- og partikkelform er strukturmessig uregelmessige og har en spesifikk overflate som i det minste går opp til 10 m 2 /g og fortrinnsvis minst 20 m 2/g. Således kan i stedenfor gassbetong anvendes skum- eller cellebetong. Although the invention is described in connection with only an aerated concrete or aerated concrete-like subject such as calcium hydrosilicate material, it is obvious that other materials can also be used. The essential thing is thus the combination that the grain and particle shape of the food material is structurally irregular and has a specific surface that is at least up to 10 m 2 /g and preferably at least 20 m 2 /g. Thus, instead of aerated concrete, foam or aerated concrete can be used.
