Abstract
The fire-protection glazing includes at least two glass panes, between which a transparent layer of a fire-protection layer is arranged, wherein the fire-protection layer includes a hydrogel. The educts of the fire-protection layer include water-soluble, non-toxic monofunctional monomers in an acid environment as well as at least one bifunctional or polyfunctional monomer and, as the case may be, an initiator, in an aqueous salt solution or in an aqueous salt dispersion. The monofunctional and the bifunctional or polyfunctional monomers are not toxic, not carcinogenic and not mutagenic.
Claims21
A fire-protection glazing with at least two transparent carriers, between which a transparent fire-protection layer is arranged, wherein the fire-protection layer comprises a hydrogel, and wherein the hydrogel comprises a polymer that is polymerised from at least one monofunctional monomer as well as at least one bifunctional or polyfunctional monomer in an aqueous salt solution or in an aqueous salt dispersion, in an acid environment.
A method for manufacturing a fire-protection glazing, comprising the steps of:
- providing a fire-protection mass with water-soluble, non-toxic, non-carcinogenic and non-mutagenic monofunctional monomers as well as with at least one bifunctional or polyfunctional monomer and with at least one initiator, in an aqueous salt solution or in an aqueous salt dispersion, in an acid environment;
- providing at least one first transparent carrier and at least one edge limitation which is peripheral along the edge of the first carrier, so that the first carrier and the edge limitation form a receptacle;
- filling the fire-protection mass into the receptacle;
- and
- controlled starting of a polymerisation of the fire-protection into a hydrogel fire-protection layer.
