Abstract: A method is described for producing phyllosilicate-intercalation compounds with an increased expansion volume and/or a modified onset temperature by intercalating intercalated compounds in native, expandable phyllosilicates, especially native vermiculite, which consists therein that the native phyllosilicate is subjected to ion exchange with at least one cationic surfactant and, at the same time or in a further step, at least one organic intercalation compound is intercalated in the phyllosilicate, with the proviso that the intercalation of dimethylformamide, chloroform, dimethylacetamide, toluene and dimethylsulfoxide can take place also without a prior ion exchange, the modified phyllosilicate-intercalation compounds obtained thereby and their use as intumescing material, which can be used as intumescing fire protection additive and/or, in expanded form, as additive for producing fire-retarding materials, as well as for producing high temperature-resistant insulation panels and seals, especially for the fir

Abstract: A method is described for producing phyllosilicate-intercalation compounds with an increased expansion rate and/or a modified onset temperature by intercalating intercalate compounds in native, expandable phyllosilicates, especially native vermiculite. The method is wherein at least one representative of the group comprising alcoholates of lithium and potassium and salts of lithium, sodium and potassium with organic acids is intercalated as intercalate compounds in the native phyllosilicate. Furthermore, the phyllosilicate-intercalation compounds obtained thereby and their use as intumescing materials, as intumescing, fire-retarding additive and/or in expanded form, can be used as additive for producing flame-retarding materials, as well as for preparing high temperature-resistant insulating panels and seals.

Abstract: A method is described for controlling the expansion properties of thermally expandable sulfuric acid-graphite particles, wherein the sulfuric acid-graphite particles, produced by the reaction of graphite particles with sulfuric acid in the presence of an oxidizing agent, are washed with an aqueous washing liquid, containing the compounds affecting the expansion properties, to a pH ranging from 2 to 8 and preferably from 3 to 7, measured in the washing liquid separated from the washed sulfuric acid-graphite particles, and then dried. Furthermore, the use of the thermally expandable sulfuric acid-graphite particles, obtainable by the method of claims 1 to 9, as intumescing fire-retarding additives for producing fire-retarding compositions especially for the fire-preventing sealing of through holes, wall bushings and other openings in walls, floors and/or ceilings of buildings, is described.
