Definitions

  • Inorganic-organic plastics based on polyisocyanates and aqueous alkali silicate solutions are known; see e.g. DT-OS 1 770 384, 2 227 147, 2 359 606, 2 359 607, 2 359 606, 2 359 609.2 359 610.2 359 611.2 359 612, DT-AS 2 325 909 and 2 310 559.
  • plastics can be produced which, due to the inorganic components, have above all improved fire resistance compared to purely organic substances and which, depending on the composition and reaction conditions, can be foamed or unfoamed, hard or soft, brittle or flexible. Due to the great variability of the properties, these inorganic-organic plastics offer a wide range of possible applications.
  • the plastics resulting from a W / 0 type dispersion are particularly interesting. They have high mechanical strengths, even when exposed to moisture, because the hardened, coherent organic phase envelops and thus fixes the likewise hardened aqueous, inorganic, incoherent phase.
  • the perfect coherent organic phase of these plastics also depends on the improved fire resistance of such systems due to the amount of water enclosed.

  • polyisocyanates are preferably made from polyphenyl-polymethylene polyisocyanates, such as those produced by aniline-formaldehyde condensation and subsequent phosgenation ('crude MDI'), and from the distillation residues obtainable therefrom by distillation of two-core products, which generally have a viscosity have between 5000 and 5000 000 mPa s / 25 ° C, an NCO content of 28-33 weight percent and a functionality> 2.
  • aqueous alkali silicate solutions or alkaline stabilized aqueous silica sols with an inorganic solid content of 20-80% by weight are also used as starting components (component b). preferably 30-70 wt .-%, used.
  • Aqueous solutions of alkali silicates are to be understood as meaning the solutions of sodium and / or potassium silicate in water which are usually referred to as “water glasses”.
  • Raw technical solutions which are e.g. Calcium silicate, magnesium silicate, borates and aluminates can be used.
  • the molar ratio Me 2 0 / S'0 2 (Me alkali metal, eg Na, K.) Is not critical and can fluctuate within the usual limits; preferably it is 1: 1.6 to 1: 3.3. If the water content of the plastic initially obtained by reaction with the polyisocyanate plays a minor role because water does not interfere or because it can be easily removed by drying, then only alkaline sodium silicate, of which 20-35% by weight can be used, can be safely used. Have% solutions made. Preferably, however, 32-54% by weight silicate solutions are used which only have the viscosity of less than 50,000 mPas required for problem-free processing if they are sufficiently alkaline. Ammonium silicate solutions, for example solutions of guanidinium silicate, can also be used, but these are less preferred. It can be real or colloidal solutions.
  • concentration mainly depends on the desired end product.
  • Compact or closed-cell materials are preferably made with concentrated silicate solutions, which are adjusted to low viscosity if necessary by adding alkali hydroxide. In this way, 40-70% by weight solutions can be produced.
  • silicate solutions with a 30-35% by weight content are preferred for the production of open-pore lightweight foams in order to achieve low viscosities, sufficiently long reaction times and low densities. Even when using finely divided inorganic fillers in larger quantities, silicate solutions of 30-35% content are preferred.
  • alkali silicate solutions which can be used according to the invention can be found in James G. Vail 'Soluble Silicates, their properties and uses', Reinhold Publishing Corporation, New York 1952.
  • Component c) can also be identical to component b) in some cases.

  • Inert mineral fillers or also hydraulic mineral binders are preferably suitable as fillers. If the dry fillers already meet the particle size criteria according to the invention (at least 50% by weight less than 50 microns), they can be mixed directly with water to form a suspension. Are the particles coarser, an aqueous coarse suspension of the fillers can also be converted into a fine suspension usable according to the invention by known methods of wet grinding.
  • Particularly preferred aqueous suspensions are those which are stable to sedimentation and show viscous, rapid flow behavior, as is known, for example, from paper coating slips. To produce such filler suspensions, it is therefore advantageous to use the methods known for the preparation of such coating slips.
  • the filler suspension can also be prepared immediately before the addition, e.g. by metering dry fillers and water into a feed line to the mixing room in which the polyisocyanate is mixed with aqueous alkali silicate and by means of a mixing device, e.g. a screw within this feed line, the aqueous filler suspension is generated in situ.
  • a mixing device e.g. a screw within this feed line
  • hydraulic binders especially cement
  • the use of hydraulic binders, especially cement generally requires suspension in water or aqueous alkali silicate immediately before processing with the isocyanate component, so that the setting process and any gelation process possibly caused by cement expediently take place in the finished plastic.
  • the filler suspensions used preferably have a viscosity above 100 mPa s in order to ensure rheological behavior which is favorable for processing. On the other hand, they should be easy to flow and should in no way have crumbly consistency. A viscosity of 10,000 mPas is preferably not exceeded. A good and very intimate mixture with the polyisocyanate in conventional processing equipment should be ensured. On the other hand, the content of fillers in the aqueous suspension should be as high as possible in order not to introduce more water than is absolutely necessary into the plastic. Depending on the particle size and the shape of the filler particles, the filler concentration is between 20 and 80%. A content of 30-70% is preferred. Lower concentrations generally have to be selected if non-spherical fillers are also used, e.g. Asbestos, talc, clays or special iron oxides.
  • isocyanate catalysts (component d) are also often used, e.g. those as described in DE-A-2 647 482, pages 13-15.
  • the catalysts are generally used in an amount between about 0.001 and 10% by weight, based on the amount of polyisocyanate.

  • Azo compounds such as azoisobutyronitrile can be achieved.
  • Suspensions as component c) which are prepared with the addition of 0.05 to 20% by weight, based on filler, of one or more of the additives listed under 1), 2) and 3) are particularly preferred.
  • the mixing of the reaction components is preferably carried out at room temperature.
  • the choice of the mixing process largely depends on the type of component c) used.
  • the batch process is preferably used when the following fillers component e) are used as aqueous suspensions with component c) (since they partially spontaneously gel aqueous alkali silicates): calcium hydroxide, magnesium hydroxide, calcium carbonate, magnesium carbonate, chalk, lime, dolomite, calcium sulfate , Gypsum and anhydride.

  • dispersions are generally obtained; which, with an increasing proportion of inorganic components and changing the W / O phase structure, undergo unstable dispersion states which, after hardening, can lead to disruptions in the structure of the inorganic-organic plastic, because inorganic substances, introduced by conventional mixing techniques, can initiate segregation processes and thus the production prevent technically usable inorganic-organic plastics.
  • plastics that can be produced according to the invention including foams, open up new possibilities in building construction and civil engineering as well as in the manufacture of finished parts and elements.
  • Examples of possible applications include the manufacture of convertible elements in prefabricated buildings, lost formwork, roller shutter boxes, window sills, railway and subway sleepers, curbs, stairs, the foaming of joints and the back-foaming of ceramic tiles.
