PHOTOCURABLE COMPOSITION FOR MANUFACTURE OF LAMINATED FIRE-RESISTANT GLASS Russian patent published in 2024 - IPC C03C27/12 

FIELD: construction.

SUBSTANCE: used in fireproof retardant building structures of windows, doors, corridors, wall structures, stained-glass windows, partitions designed to prevent the spread of smoke and fire in the event of a fire outside the insulated compartment. A photocurable composition for the manufacture of laminated fire-resistant glass, containing an acrylic monomer, a water-soluble salt, a photoinitiator of polymerization, a cross-linking agent and water additionally contains a carbon-salt coke disintegrant, an ultraviolet filter, an acidity regulator, a fire retardant and a transparency stabilizer in the following ratio of components, wt.%: acrylic monomer 6-14; water-soluble salt 16-30; photoinitiator of polymerization 0.01-0.1; crosslinking agent 0.01-0.1; carbon-salt coke disintegrant 0.05-1.0; ultraviolet filter 0.1-1.0; acidity regulator 0.003-0.5; fire retardant 0.01-0.1; transparency stabilizer 0.01-0.1; water - the rest.

EFFECT: increasing the fire resistance of laminated glass while simultaneously increasing stability and service life (shelf life) in wide temperature ranges.
