MULTILAYER LAMINATED GLASS Russian patent published in 1995 - IPC

FIELD: production of multilayer laminated safety glass. SUBSTANCE: two silicate glass panels are joined by means of intermediate adhesive from polyvinyl butyral or thermoplastic polyurethane. Used for adhesive layer may be film of copolymer of ethylene and vinyl acetate cross-linked in the process of cementing under the action of heat and organic peroxide. To reduce gas evolution in the process of cementing and to simplify cementing process, it is recommended to cement with film from copolymer of ethylene and vinyl acetate cross-linked under the effect of accelerated electron beam up to value of gel-fraction of 36-75%. EFFECT: higher efficiency. 2 cl
