FIELD: material engineering.
SUBSTANCE: present invention relates to a photopolymerizing composition for the manufacture of sheet materials used as the front part of LED outdoor advertising displays. The photopolymerizing composition contains 15-45 wt. % of polymethylmethacrylate production waste; 0.10-2 wt. % hydrophobic oil; 0.05-3 wt. % emulsifier (surfactant); 0.20-5 wt. % of the initiator of photopolymerization; 0.01-3 wt. % titanium dioxide; 0.05-2 wt. % stearic acid and acrylic monomer the rest.
EFFECT: products obtained from this composition are characterized by high physical and mechanical and optical characteristics, and the composition also provides high manufacturability during processing using liquid acrylic technology, uniform curing without the formation of voids, cavities, warping and other defects.
