FIELD: personal use articles.
SUBSTANCE: invention relates to a method for production of a layered decorative material of acetatecellulose plastic. The method consists in pre-treatment of the sheet materials surface with a solution of bis(tret-butylperoxiizoproryl)benzol in an organic solvent (acetone) with a concentration of 0.5-1.5% taken in an amount calculated for 50-150 g/m2. Then the sheets are weld-joined with high frequency currents at a wattage of 200-250 kW and current frequency 39.68-41.68 mHz during 2-4 seconds The layered sheet material has a number of layers varying from 2 to 6; the layers are differently coloured or differ in terms of translucency.
EFFECT: resultant product is noted for improved strength performance and is utilised for manufacture of glass rims and different accessories.
