FIELD: chemistry.SUBSTANCE: invention relates to varnish-and-paint material, modified by nano-dispersive layered silicates, dispersed in solution of highly molecular compound by means of ultrasonic processing. Varnish is applied for procession of products and constructions from concrete, metal, wood, bricks and other materials. Varnish base represents bitumen of brand G and solvent, which represents mixture of xylene and white spirit in ratio 1:1. Bituminous varnish additionally contains organophilic nano-dispersive layered silicates, distributed in solution of bituminous resin. Ratio of bitumen of brand G, xylene, white spirit and organophilic nano-dispersive layered silicates constitutes respectively 1-1.12:0.58-0.65 0.58-0.65:0.03.EFFECT: modified in such way varnish-and-paint material has improved characteristics, in particular, increased moisture-protecting properties, and this does not require fundamental changes of the technological process of its production.1 dwg, 1 ex |
