Abstract

1450240 Modified polyisocyanate/aqueous silicate reaction products BAYER AG 27 Nov 1974 [30 Nov 1973] 51299/74 Heading C3R Flexible polymeric materials are obtained by mixing (a) 30-70 wt. per cent of a compound having at least 2 reactive H atoms, of molecular weight 400-6000 and glass transition temperature below 10‹ C., (b) 10-30 wt. per cent of a polyisocyanate and (c) 20-60 wt. per cent of an aqueous alkali metal or ammonium silicate solution of 30-70 wt. per cent solids content. Preferably (a) and/or (b) contains a hydrophilic group, and these two are preferably mixed first to give a prepolymer. The products are usually foams, and conventional blowing agents and other polyurethane foam additives and fillers may also be added. In Examples 150 p.b.w. (total) of a mixture of a polyoxypropylene polyol/TDI prepolymer which may be sulphonated with SO 3 , with 20-60 p.b.w. (usually 50) of a crude polyphenyl polymethylene polyisocyanate modified with a polyoxyethylenated butanol is mixed with 30-50 p.b.w. of CCl 3 F, and this mixture combined with one containing 100-200 p.b.w. of 44% aqueous sodium silicate (Na 2 O : SiO 2 , 1 : 2), 0À5-2 p.b.w. of Et 3 N, optionally 1À5-3 p.b.w. of an emulsifier or silicone foam stabilizer and, in Examples 2-4, and 15-17, 50-200 p.b.w. of cement; in Examples 20-26 a one-shot process is carried out using 100 p.b.w. of polypropylene glycol 10 p.b.w. of TDI and 60 p.b.w. of an unmodified and/or sulphonated or polyglycol-modified polyphenyl polymethylene polyisocyanate with CFCl 3 and waterglass and optional triethylamine and silicone in quantities as above. Reference has been directed by the Comptroller to Specification 1,186,771.
