US 10,961,154 B2 · Geopolymer composite and expandable vinyl aromatic polymer granulate and expanded vinyl aromatic polymer foam comprising the same

Abstract

The present invention relates to a process for the production of a geopolymer composite. It further relates to a geopolymer composite, and the use of a geopolymer, a geopolymer in combination with an athermanous additive, or the geopolymer composite in expanded vinyl polymer, preferably vinyl aromatic polymer. Furthermore, the invention relates to a process for the production of expandable vinyl aromatic polymer granulate, and expandable vinyl aromatic polymer granulate. Finally, the present invention relates to expanded vinyl foam, preferably vinyl aromatic polymer, and to a masterbatch comprising vinyl polymer and a), b), or c).

Claims3

Dependent claims

Expandable vinyl aromatic polymer granulate comprising a mixture of vinyl aromatic polymer, one or more propellants, and a geopolymer composite derived from geopolymer and comprising athermanous additive,

wherein the athermanous additive comprises at least one athermanous additive selected from the group consisting of carbon black, petroleum coke, graphitized carbon black, graphite oxides, graphite, graphene, rutiles, chamotte, fly ash, fumed silica, hydromagnesite/huntite mineral, and mineral having perovskite structure, and
wherein the one or more propellants is present in an amount of 2.0 wt. % to 9.0 wt. % based on total mass of the granulate including the one or more propellants.

Dependencies are inferred from the claim text.
