| titleOfInvention | Highly filled polyurea foams |
| abstract | HIGHLY FILLED POLYUREA FOAMS ABSTRACT OF THE DISCLOSURE The instant invention relates to hydrophobic inorganic-organic lightweight foams produced from aqueous suspensions of finely divided water-insoluble inorganic materials and polyisocyanates. More particularly, the invention relates to a process for the production of highly filled, hydrophobic, lightweight polyurea foams comprising reacting (a) liquid, water/soluble polyisocyanates free from ionic groups, having viscosities of more than 200 cP at 25°C and having isocyanate functionalities of greater than 2.1, with (b) an aqueous suspension of inorganic filler, said suspension having a solids content of from 30 to 80 percent by weight and having a pH value of above 8, at least 50 percent by weight of the suspended fillers having a particle size of less than 50 microns, (c) in the presence of a foam stabilizer of the polyether tertiary polysiloxane type and in the presence of a tertiary amine catalyst, the weight ratio of components (b) to component (a) being better 1:2 and 6:1. |
