PAINT AND VARNISH COMPOSITE FOR PROTECTION AGAINST RADIATION Russian patent published in 2002 - IPC

FIELD: protective composites. SUBSTANCE: invention relates to composites for preparing film used for protection of different surfaces against ionizing radiation. Composite comprises the following components, wt.-%: block polystyrene of grade PSB, 8.9-12.4; o-xylene, 39.7-45.1; optical glass waste with specific surface 350 m²/kg, 45.8-47.6; dibutyl phthalate, 0.2-0.3. Composites show viscosity 35-43 s, working life, 225-255 min; adhesion to backing, 1.83-2.14 MPa and average density 2340-2420 kg/m³. Invention provides decrease of viscosity, enhancement of working life, adhesion to backing and average density of composites. EFFECT: improved properties of composites. 2 tbl
