Abstract
The present invention is directed to a method of preparing non-flammable thermal insulation foam, comprising the steps of (a) providing a mixture comprising (1) at least one water soluble alkali metal silicate, (2) optionally, at least one filler, and (3) at least one inorganic material which releases non-flammable gases when exposed to heat; (b) applying the mixture to a support or mold; and (c) heating the mixture to form the non-flammable thermal insulation foam.
