CELLULAR MATERIALS BASED ON SILICATES AND POLY (METH) ACRYLIC ACIDS, THEIR PREPARATION AND THEIR APPLICATION

摘要

The invention relates to inorganic-organic cellular materials. To manufacture them, a mixture is mixed (A) with a water-soluble solution of 5-60 by weight of a metal silicate. ALKALINE OR AMMONIUM, (B) SUFFICIENT QUANTITY OF A USUAL CURING SOURCE FOR AQUEOUS SOLUTIONS OF SILICATES, (C) A POLYMER OR COPOLYMER OF ACRYLIC ACID OR METHACRYLIC ACID, SOLUBLE IN THE SOLUTION A SILICATE AQUEOUS, (D) A POROGENE, (E) A FOAM-ACTING SURFACTANT AND POSSIBLY (F) A GELIFIER FOR THE CONSOLIDATION OF THE FOAM BEFORE HARDENING AND OTHER USUAL LOADS, AND CURING THE FOAM THUS CREATED. / P P THESE CELLULAR MATERIALS CAN BE USED AS INSULATING MATERIALS IN THE BUILDING INDUSTRY. / P
