METHOD OF MANUFACTURE OF LAMINATED GLASS

摘要

FIELD: manufacture of laminated glass. SUBSTANCE: proposed method includes placing at least one third layer on base of polymer composition between at least one first layer and at least one second layer followed by hardening. First layer is obtained through polymerization co-polymerization of methyl methacrylate till conversion of 50-98 %. Used as third layer is layer common with first layer on base of monomers and/or polymer of different composition as compared with first layer. Layer subjected to orientation may be used as first layer. Orientation is performed by stretching to 40-180 % at temperature higher than glass transition temperature of product subjected to stretching. Layer obtained through polymerization and/or co- polymerization of methyl methacrylate with bi- or polyfunctional monomers, for example diallyliso phthalate may be used as first layer. Soda-lime or acrylic glass may be used as second layer; layer on base of monomers and/or polymers of (metha)acryl series or on base of polyvinyl butyral may be used as third layer. Hardening may be performed at temperature of 110-170 C, as well as by molding with force applied normally relative to first and third layers. EFFECT: enhanced efficiency. 13 cl, 1 tbl, 1 ex
