摘要:
A fire-barrier system comprises at least one alkali silicate resin composition layer and at least one layer of any of the following: an insulation layer, an intumescent layer, a foam layer, a corrugated layer, a reflective surface layer, and a reinforcing material layer. The fire-barrier system when utilize in association with a substrate such as wood, a polymer, etc. provides enhanced fire resistance performance, thermal barrier, an oxidation barrier, and the like.
摘要:
A light-weight, heat distortion resistant laminate includes at least one layer of an alkali silicate resin composition derived from an alkali silicate and/or alkali silicate precursor, at least one oxoanionic compound or a reactive acidic glass; and water; and at least one reinforcing core layer comprising an inorganic high-temperature resistant composition. The laminate has a very low quench steepness index value upon rapid quenching as with ambient temperature water.
摘要:
A modified alkali silicate composition for forming an inorganic network matrix. The modified alkali silicate matrix is made by reacting an alkali silicate (or its precursors such as an alkali hydroxide, a SiO2 source and water), an acidic inorganic composition, such as a reactive glass, water and optional fillers, additives and processing aids. An inorganic matrix composite can be prepared by applying a slurry of the modified aqueous alkali silicate composition to a reinforcing medium and applying the temperature and pressure necessary to consolidate the desired form. The composite can be shaped by compression molding as well as other known fabrication methods. A notable aspect of the invention is that, although composite and neat resin components prepared from the invention can exhibit excellent dimensional stability to 1000° C. and higher, they can be prepared at the lower temperatures and pressures typical to organic polymer processing.

摘要:
A modified alkali silicate composition for forming an inorganic network. The modified alkali silicate matrix is made by reacting an alkali silicate (or its precursors such as an alkali hydroxide, a SiO2 source and water), an acidic oxoanionic compound such as phosphoric acid, water and optionally one or more multivalent cation(s) selected from Groups 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 or 16 of the periodic table such as an alkaline earth salt, water and optional processing aids. An inorganic matrix composite can be prepared by applying a slurry of the modified aqueous alkali silicate composition to a reinforcing medium and curing the composite at a temperature from about 15° C. up to 1000° C. and a pressure of up to 20,000 psi for typical high-performance organic polymer processing (temperatures about 15° C. to about 200° C. and pressures
