FIELD: glass industry; methods of manufacture of the multilayered shatterproof glasses.
SUBSTANCE: the invention is pertaining to the field of glass industry, in particular to a method of production of the multilayered shatterproof glasses. The invention presents a single-stage process of manufacture of the multilayered shatterproof glass not providing the glasson treatment in an autoclave. The multilayered shatterproof glasses consist of at least two protective glasses and an interlayer made out of a containing a plasticizer partially acetalizated polyvinyl alcohol in the form of a film, the roughness of which Rz has a value between 75 and 150 microns. The film has the non-regular structure of its roughness. The technical result of the invention is a decrease of the cost and labor input for realization of the method of manufacture of the multilayered shatterproof glasses.
EFFECT: the invention ensures a decrease of the cost and labor input for realization of the method of manufacture of the multilayered shatterproof glasses.
