Geopolymer composite and expandable vinyl aromatic polymer granulate and expanded vinyl aromatic polymer foam comprising the same

The present invention relates to a simple process for the production of geopolymer or geopolymer composite comprising additive. The process preferably comprises modification of the geopolymer or geopolymer composite. The invention further relates to a geopolymer or geopolymer composite as obtainable according to the process.

Process for the production of geopolymer or geopolymer composite

The invention relates to the use of i) geopolymer and ii) non-brominated, phosphorus- and/or nitrogen-based flame retardants for improving the self-extinguishing properties of a composition comprising polymer. The polymer may be a vinyl aromatic polymer, and may be in a granulate or foam.

Use of geopolymeric additive in combination with non-brominated flame retardant in polymer foams

The invention relates to the use of a mineral having perovskite structure in vinyl aromatic polymer foam, i) for decreasing the thermal conductivity, ii) for increasing the mechanical properties (namely compressive strength and bending strength), or iii) for improving the self-extinguishing properties of the foam. The polymer foam further comprises one or more athermanous additives selected from a) powder inorganic additive selected from powders of silica and calcium phosphate, b) powder carbonaceous additive selected from powders of graphite, carbon black, petroleum coke, graphitized carbon black, graphite oxides, and graphene, and c) powder geopolymer and powder geopolymer composite.

Use of a mineral having perovskite structure in vinyl aromatic polymer foam

The invention relates to the co-use of a) a certain type of silica and b) a certain type of graphite, wherein the silica and the graphite are used in a weight ratio in a range of from 1:1 to 1:10, for decreasing the thermal conductivity of vinyl aromatic polymer foam.
