Description
Fremgangsmåte til fremstilling av granulert bestrøingsmaterale for takpapp. Process for the production of granulated covering material for roofing felt.
På takpapp med bituminøst overflatebelegg pålegges ofte et lag granulert be-strøingsmateriale som dels har til øyemed On roofing felt with a bituminous surface coating, a layer of granulated bedding material is often applied, partly with the aim of
å beskytte takpappen mot atmosfærens to protect the roofing felt from the atmosphere

Økonomisk sett er det chipped or peeled opaque material which also has a large contact surface against the bitumen and therefore sticks particularly well to it. Financially, it is
videre av vesentlig betydning at man med further of essential importance that one with
en slik kornform oppnår tilstrekkelig dekning med et tynt lag og derved får stor such a grain shape achieves sufficient coverage with a thin layer and thereby gets large

Slik brent flint fremstilles av hensyn til Burnt flint like this is produced in consideration of

Foreliggende oppfinnelse går ut på å The present invention is based on
fremstille et for takpapp godt egnet, granulert bestrøingsmateriale av brent flint, produce a granulated covering material from burnt flint that is well suited for roofing felt,
hvilket i henhold til oppfinnelsen oppnås which according to the invention is achieved
ved at råflinten først knuses og deretter in that the raw flint is first crushed and then
brennes. Råflinten har i motsetning til is burned. Raw flint has, in contrast,

flisede eller skjellede korn som imidlertid er uegnet i det foreliggende øyemed på grunn av sin mørke farge og gjennomskin-nelighet. Disse flisede og skjellede korn har imidlertid ytterligere den egenskap at de bevarer sin form ved brenning, og herved farges hvite og ugjennomsiktige. Oppfinnelsen går derfor ut på til fremstilling av bestrøingsmateriale til takpapp å anvende flint som først er knust og dernest er hvitbrent. Fremgangsmåten kan gjennomføres meget enkelt, idet flintestenen kan knuses og siktes på alminnelige knuseverker og brennes i alminnelige til brenning av sten-materialer benyttede ovner. chipped or shelled grains which, however, are unsuitable for the present purpose because of their dark color and translucency. These chipped and shelled grains, however, have the further property that they retain their shape when fired, and are thereby colored white and opaque. The invention is therefore based on using flint which is first crushed and then white-burnt for the production of covering material for roofing felt. The procedure can be carried out very simply, as the flint can be crushed and sieved in ordinary crushing plants and burned in ordinary kilns used for burning stone materials.
Ved oppfinnelsen oppnås den store fordel at man bare behøver å brenne den del av den knuste råflint som ved siktning eller på annen måte er frasortert som pas-sende til den påtenkte anvendelse. The invention achieves the great advantage that one only needs to burn the part of the crushed crude flint which, by sifting or in some other way, has been sorted out as suitable for the intended use.
Det har vist seg at på denne måte fremstilt hvitt og fliset materiale er ual-minnelig godt egnet til fremstilling av farget bestrøingsmateriale. Det gjør det mu-lig, særlig å fremstille korn som gir en helt bestemt ønsket fargevirkning, og man kan således blant annet ta hensyn til at det nå i mange tilfelle forlanges at en tak-flate skal ha en slik farge at den av hensyn til kamuflasje ikke gir særlig inntrykk på infrarød film ved fotografering fra luf-ten. Hvitbrent flint vil selv ved anvendelse av en mindre mengde fargestoff gi pene, klare, dekkende bestrøingsmaterialer som er helt ugjennomskinnelige, og derved i særlig høy grad beskytter takpappens bi-tuminøse overflatelag mot atmosfærens påvirkning. It has been shown that white and chipped material produced in this way is generally well suited for the production of colored sprinkling material. This makes it possible, in particular, to produce grain that gives a completely specific desired color effect, and one can thus, among other things, take into account the fact that in many cases it is now required that a ceiling surface must have such a color that, for reasons of camouflage does not give much impression on infrared film when photographing from the air. Even when a small amount of dye is used, white-burnt flint will give neat, clear, covering covering materials that are completely opaque, thereby protecting the bituminous surface layer of the roofing felt to a particularly high degree against the effects of the atmosphere.
I forbindelse hermed skal bemerkes at det fra norsk patent nr. 55 490 er kjent å anvende kunstbestrøningsmateriale fremstilt ved knusing av kunststen som er fremstilt av fargede mørtler, eventuelt med tilsetningsstoffer som sand, stenmel, flint etc. In connection with this, it should be noted that from Norwegian patent no. 55 490 it is known to use artificial bedding material produced by crushing artificial stone made from colored mortars, possibly with additives such as sand, stone flour, flint etc.
Fra U.S. patent nr. 2 004 682 er det kjent å fremstille fargede bestrøningsma-terialer ut fra sten eller keramiske mate-rialer ved påbrenning av fargestoffer (ok-syder) ved hjelp av et glasurmateriale be-stående av finmalt glasspulver. Pulveret kan tilsettes fluksningsmidler som boraks og blyoksyd. From the U.S. patent no. 2 004 682, it is known to produce colored sprinkling materials from stone or ceramic materials by burning dyes (ok-sider) with the help of a glaze material consisting of finely ground glass powder. Fluxing agents such as borax and lead oxide can be added to the powder.
Som nevnt er foreliggende oppfinnelse kjennetegnet ved at råflint først knuses og deretter brennes. Farging av stenkornene kan enten skje i en selvstendig pro-sess etter flintens knusing og brenning eller samtidig med brenningen. Samtidig brenning og farging er mer økonomisk og gir en enklere produksjonsprosess. As mentioned, the present invention is characterized by raw flint being first crushed and then burned. Coloring of the stone grains can either take place in an independent process after the flint is crushed and fired or at the same time as the firing. Simultaneous burning and dyeing is more economical and provides a simpler production process.
Således adskiller fremgangsmåten i henhold til oppfinnelsen seg klart fra fremgangsmåten i henhold til det norske patent nr. 55 490 ved at stenkornene først farges etter knusing og sikting til den øn-skede kornstørrelse, og ved at stenkornene bare farges på sin overflate. I forhold til de gjennomfargete bestrøningsmaterialer som er nevnt i norsk patent nr. 55 490 krever overflatefargede bestrøningsmaterialer i henhold til foreliggende oppfinnelse bety-delig fargestoffmengder til farging, hvilket er av vesentlig økonomisk betydning. Thus, the method according to the invention clearly differs from the method according to the Norwegian patent no. 55 490 in that the stone grains are first colored after crushing and sifting to the desired grain size, and in that the stone grains are only colored on their surface. In relation to the through-dyed sprinkling materials mentioned in Norwegian patent no. 55 490, surface-dyed sprinkling materials according to the present invention require significant amounts of dye for dyeing, which is of significant economic importance.
Ved overflatefarging er det nødvendig å anvende fint fordelte glasurmaterialer på grunn av glasurlagets ringe tykkelse (50 (x eller mindre). I U.S. patent nr. 2 004 682 er det beskrevet anvendelsen av glass som hovedbestanddel av glasuren og dette glass må knuses til stor finhet før bruken. For surface coloring, it is necessary to use finely divided glaze materials due to the small thickness of the glaze layer (50 (x or less). In U.S. Patent No. 2,004,682, the use of glass as the main component of the glaze is described and this glass must be crushed to great fineness before use.
Ved fargeprosessen i henhold til oppfinnelsen anvendes glassråstoffer som er enten vannoppløselige eller lett tilgjenge-lige i findelt form. Vannoppløselige glassråstoffer er f. eks. boraks, vannglassopp-løsning, soda, potaske, etsnatron og etskali. Glassråstoffer som koalin, kiselkritt, kiselgur og kritt finnes i naturen i stor finhet, mens glassråstoffer som mønje og sinkhvitt fremkommer i findelt form ved sin fremstilling. In the coloring process according to the invention, glass raw materials are used which are either water-soluble or easily available in finely divided form. Water-soluble glass raw materials are e.g. borax, water glass solution, soda, potash, caustic soda and lye. Glass raw materials such as koalin, diatomaceous chalk, diatomaceous earth and chalk are found in nature in a very fine form, while glass raw materials such as slag and zinc white appear in finely divided form during their manufacture.
Videre adskiller fargeprosessen i henhold til oppfinnelsen seg fra fargeprosessen i henhold til U. S. patent nr. 2 004 682 ved at der ikke anvendes et ferdig smeltet glass, men at glasset først dannes av glass-råstoffene under brenningen. Furthermore, the coloring process according to the invention differs from the coloring process according to U. S. patent no. 2,004,682 in that a ready-melted glass is not used, but that the glass is first formed from the glass raw materials during firing.
I det følgende er det angitt tre ek-sempler på oppfinnelsens utførelse: In the following, three examples of the embodiment of the invention are given:
Eksempel 1: Example 1:
Rå flintknoller knuses til stykker mindre enn ca. 50 mm med en kjeftknuser. De fremkommende flintstykker knuses ytterligere i en valsestol med to glatte val-ser. Den del av det således knuste materiale som har kornstørrelser mellom 0,5 mm og 1,5 mm siktes fra. Det grove materiale knuses igjen i valsestolen. Utbyttet av knust flint av størrelsen 0,5—1,5 mm er ca. 50 pst. Raw flint tubers are crushed into pieces smaller than approx. 50 mm with a jaw crusher. The resulting flint pieces are crushed further in a rolling mill with two smooth rollers. The part of the thus crushed material which has grain sizes between 0.5 mm and 1.5 mm is sieved. The coarse material is crushed again in the roller bed. The yield of crushed flint of the size 0.5-1.5 mm is approx. 50 percent
Den knuste flint føres til en roterende ovn, i hvis varme ende temperaturen er ca. 1000° C, og gjennom hvilken flinten passerer i løpet av V2 time. Den knuste og brente flint har en hvit, matt farge og kan direkte anvendes som bestrøningsmateriale for takpapp. The crushed flint is taken to a rotating furnace, at the hot end of which the temperature is approx. 1000° C, and through which the flint passes in V2 hour. The crushed and burnt flint has a white, matt color and can be used directly as a sprinkling material for roofing felt.
Eksempel 2: Example 2:
Et rødt bestrøningsmateriale til takpapp kan fremstilles på følgende måte: 1000 kg knust og brent flint fremstilt som beskrevet i eksempel 1, blandes grundig med: 17,'5 kg gult jernoksyd 18,0 » boraks 14,4 » etskali 21,6 » vannglassoppløsning (34 %) A red sprinkling material for roofing felt can be produced in the following way: 1000 kg of crushed and burnt flint prepared as described in example 1, is thoroughly mixed with: 17.5 kg yellow iron oxide 18.0 » borax 14.4 » caustic soda 21.6 » water glass solution (34%)
i en egnet beholder med langsomt dreiende rørevinger. Blandingen av flint, fargestoff og glasurkomponenter brennes i den roterende ovn ved ca. 700° C. Det gule fargestoff blir rødt ved brenningen og fasthol-des på flintkornene av de sammensmeltede glasurkomponenter. in a suitable container with slowly rotating stirrer blades. The mixture of flint, dye and glaze components is fired in the rotary kiln at approx. 700° C. The yellow dye turns red during firing and is held onto the flint grains by the fused glaze components.
Eksempel 3: Example 3:
Et grønt bestrøningsmateriale til takpapp kan fremstilles på følgende måte: 1000 kg knust, men ubrent flint som beskrevet i eksempel 1, første avsnitt, blandes grundig med: 15 kg kromoksyd II » kiselkritt 6 » boraks 2,5 » etsnatron A green sprinkling material for roofing felt can be produced in the following way: 1000 kg of crushed but unburnt flint as described in example 1, first paragraph, is thoroughly mixed with: 15 kg of chromium oxide II » silica chalk 6 » borax 2.5 » caustic soda
30 » vann 30 » water
i en egnet beholder med langsomt dreiende rørevinger. Blandingen brennes i en roterende ovn ved ca. 1000° C. Ved brenningen smelter glasurkomponentene og fastholder det grønne fargestoff på flintkornene som samtidig brennes hvite. in a suitable container with slowly rotating stirrer blades. The mixture is fired in a rotary kiln at approx. 1000° C. During firing, the glaze components melt and retain the green dye on the flint grains, which are also fired white.
Fargingen kan foretas ved anvendelse av kjente metoder, f. eks. ved anvendelse av vannglass, plastlakker eller ved påbrenning eller påsintring av glasurer som inneholder fargede stoffer som kan tåle opp-varmning. Det er i henhold til oppfinnelsen særlig gunstig for farging av det foreliggende granulerte bestrøningsmateriale å foreta påbrenningen eller påsintringen under tilstedeværelse av glasurmateriale som inneholder fargende stoffer, f. eks. krom-oksydgrønt, under brenning av den knuste flint, hvorved man ytterligere oppnår å få fremstilt et dekningsmateriale som har meget stor refleks på infrarød film og derfor er godt egnet for den ovenfor omtalte kamuflasje. The staining can be carried out using known methods, e.g. when using water glass, plastic varnishes or when firing or sintering glazes that contain colored substances that can withstand heating. According to the invention, it is particularly advantageous for coloring the present granulated sprinkling material to carry out the firing or sintering in the presence of glaze material containing coloring substances, e.g. chrome-oxide green, during burning of the crushed flint, whereby one further achieves the production of a covering material which has a very high reflectivity on infrared film and is therefore well suited for the camouflage mentioned above.
Ved å gå frem i henhold til oppfinnelsen kan man videre på enkel måte forsyne den flisede flint med særlig hydrofobt overflatebelegg, idet brenningen også til dette formål i henhold til oppfinnelsen kan foretas under tilstedeværelse av glasurmateriale som herved påsmeltes eller påsintres på flintmaterialets overflate. By proceeding according to the invention, one can further provide the chipped flint with a particularly hydrophobic surface coating in a simple way, as the firing can also be carried out for this purpose according to the invention in the presence of glaze material which is thereby melted or sintered onto the surface of the flint material.
Ved å arbeide på de beskrevne måter By working in the ways described
oppnås videre den fordel at man ved fremstilling av et slikt overflatebehandlet og eventuelt samtidig farget flintmateriale kan nøyes med en enkelt brenning. furthermore, the advantage is achieved that when producing such a surface-treated and possibly simultaneously colored flint material, one can be content with a single firing.
