Det nett-oppnevnte kittmel består av minst ett in-ert fyllstoff og minst en anorganisk og/eller mortar, i.e. masses made up of sodium water glass and/or potassium water glass solutions and a suitable putty flour.

Man kan da fremstille kitt- og mørtelmel som i praksis har meget lang lagringsevne — inntil et år og mere — ved romtemperatur, dvs. ved ca. 20° C, hvilke kan blandes med natron-, og/eller kalivannglassoppløsninger av en sammensetning som strekker seg over et stort område. Forarbeidningstiden for de blandede kitt- henholdsvis mørtelmasser ligger ved romtemperatur på mellom ca. 10 og ca. 60 minutter. For de natrium-vannglass som skal anvendes for kittmassene ifølge oppfinnelsen kan forholdet as they are formed by the action of water on the NH^ - and amide compounds. You can then produce putty and mortar flour which in practice has a very long shelf life - up to a year or more - at room temperature, i.e. at approx. 20° C, which can be mixed with soda ash and/or potash water glass solutions of a composition that extends over a large area. The processing time for the mixed putty or mortar masses is at room temperature between approx. 10 and approx. 60 minutes. For the sodium-water glasses to be used for the putty masses according to the invention, the ratio can

ligge innenfor området 1,9 til 2,6. Natrium-eller kaliumvannglass eller blandinger av begge arter vannglass anvendes fortrinnsvis i form av sine vandige oppløsninger. Som vannglassoppløsninger kan det også anvendes kiselsyrerike vannglass, f. eks. lie within the range 1.9 to 2.6. Sodium or potassium water glass or mixtures of both types of water glass are preferably used in the form of their aqueous solutions. Silica-rich water glasses can also be used as water glass solutions, e.g.

Som utgangsmateriale for fremstilling av de selvherdende vannglasskittmasser kan det også anvendes vannglass show a high water content, which is important for thin-flowing masses, e.g. for floor fastening. Water glass can also be used as a starting material for the production of the self-hardening water glass putty compounds

Med særlig fordel kan det fra rekken av de oppførte forbindel- amide, triazetamide, malonamide. Of the series of amides, e.g. further mentioned: sulfonic acid amides and/or amides of organic phosphoric acid derivatives. With particular advantage, from the series of the listed connec-
ser anvendes amider, særlig formamid og cyanamid. I stedet for cyanamid kan det også anvendes derivater av cyanamid, amides are used, especially formamide and cyanamide. Instead of cyanamide, derivatives of cyanamide can also be used,

Gode resultater fåes f. eks. når det på 100 vektsdeler av et kittmel anvendes 25 til 35 vektsdeler vannglassoppløsning av de ovenfor nevnte sammensetningsgrenser. I visse tilfelle kan imidlertid mengdeforholdet vannglassopp-løsning til kittmel også ligge høyere eller lavere. that of the individual components and can vary within wide limits. Good results are obtained e.g. when 25 to 35 parts by weight of a water glass solution of the above-mentioned composition limits are used on 100 parts by weight of a putty flour. In certain cases, however, the quantity ratio of water glass solution to putty flour can also be higher or lower.
Som inaktive fyllstoffer som egner seg As inactive fillers that are suitable
til fremstilling av kittmassene ifølge oppfinnelsen skal f. eks. nevnes: kvartssand og kvartspulver. Ved siden av dette kan imidlertid også anvendes andre silikat-pulvere, f. eks. glasspulvere, porselens-pulvere, chamottepulver og stentøypulver. for the production of the putty compounds according to the invention, e.g. mentioned: quartz sand and quartz powder. Alongside this, however, other silicate powders can also be used, e.g. glass powders, porcelain powders, chamotte powders and stoneware powders.
I mange tilfelle kan det også anvendes fyll- In many cases, filling can also be used
stoffer med en god varmeledningsevne, slik som naturlig eller kunstig grafitt, silicium-karbid, silicium eller liknende. I mange tilfelle er det også fordelaktig å anvende blandinger av forskjellige fyllstoffer. substances with a good thermal conductivity, such as natural or artificial graphite, silicon carbide, silicon or the like. In many cases, it is also advantageous to use mixtures of different fillers.
Av og til kan det også være gunstig å anvende andre faste stoffer, f. eks.: «kisel- From time to time it can also be beneficial to use other solid substances, e.g.: "silica

Ved siden av de nevnte NH2- resp. Next to the aforementioned NH2- or
amidgruppeholdige og herdende virkende forbindelser kan det også tilblandes ennu videre derivater av anorganiske alifatiske syrer som middel for herdeforbedring. De sistnevnte syrer skal derved ha en ekviva-lent-vekt som ikke overstiger verdien 60. amide group-containing and hardening-acting compounds can also be mixed with even further derivatives of inorganic aliphatic acids as a means of improving hardening. The latter acids must therefore have an equivalent weight that does not exceed the value 60.
Som egnede derivater skal f. eks. nevnes: maursyreester av glykol henholdsvis av glycerin, estere av flerbasiske syrer, slik som oksalsyredimetylester, og estere av oksysyrer, slik som sitronsyre. Med særlig fordel kan det anvendes indre estere av oksykarbonsyrer, f. eks. glykolid (polymeri- As suitable derivatives, e.g. are mentioned: formic acid esters of glycol or of glycerin, esters of polybasic acids, such as oxalic acid dimethyl ester, and esters of oxyacids, such as citric acid. Inner esters of oxycarboxylic acids can be used with particular advantage, e.g. glycolide (polymeri-
serte indre estere av glykolsyre). Videre kan det også anvendes syreanhydrider, f. serte internal esters of glycolic acid). Furthermore, acid anhydrides can also be used, e.g.

Man kan imidlertid også gå frem således at fast vannglass i pulverform allerede sammen-blandes med de øvrige bestanddeler av kittmelet og denne blanding tilsettes der- other substances and then add the water glass solution to the putty. However, it is also possible to proceed in such a way that solid water glass in powder form is already mixed with the other components of the putty flour and this mixture is added there-

Eksempel: Example:
100 vektsdeler kittmel som består av 97,5 vektsdeler kvartsmel av forskjellige kornstørrelser som på en 10.000 maskers sikt gir en rest på ikke mer enn . 10 — 25 100 parts by weight of putty flour which consists of 97.5 parts by weight of quartz flour of different grain sizes which on a 10,000 mesh sieve gives a residue of no more than . 10 — 25
pst., og 2,5 vektsdeler formamid blandes med 35 vektsdeler av en kali-vannglass-oppløsning med forholdet — — - = 2,50 — pst., and 2.5 parts by weight of formamide are mixed with 35 parts by weight of a potassium-water glass solution in the ratio — — - = 2.50 —
K20K20
2,55. Formamidet inneholder derved bare 0,25 — 1,0 pst. av sin vekt av ammonium-formiat. Vannglasskittmassen har etter blanding en forarbeidelsestid på 25 — 10 minutter og herder deretter av seg selv. 2.55. The formamide thus contains only 0.25 - 1.0 per cent of its weight of ammonium formate. After mixing, the water glass putty has a processing time of 25 - 10 minutes and then hardens on its own.
En tilsetning av 0,05 pst. glykolid (indre An addition of 0.05 percent glycolide (inner
ester av glykolsyre), beregnet på kittmelet er mulig. I stedet for formamid kan det også anvendes en cyanamid, f. eks. CaCN2. ester of glycolic acid), intended for the putty flour is possible. Instead of formamide, a cyanamide can also be used, e.g. CaCN2.
I stedet for K-glass kan det også anvendes Instead of K-glass it can also be used
