COMPOSITE THERMOPLASTIC MATERIAL Russian patent published in 2006 - IPC C08L23/02 

FIELD: polymer materials.

SUBSTANCE: invention relates to polymer material science and can be used to manufacture structural elements of various functional destinations. Composite thermoplastic polyolefin-based material contains filler and fire-retardant additive, the former being thermally treated silicate, namely product of treatment of naturally occurring silicates by heat stroke with gradient 800-1000°C, and the latter being halogen-containing oligomer selected from group including chloroparaffin and fluorine-containing oligomer ("Foleoks"), whereas above-mentioned polyolefin is selected from group including polypropylene, low-pressure polyethylene, high-pressure polyethylene, ethylene/vinyl acetate copolymer, and thermomechanically combined mixture of polyolefins with polyolefins, polyacetals, or styrene-containing plastics.

EFFECT: improved physico-mechanical characteristics of composite polyolefin-based material and increased resistance to burning and to action of negative temperatures.
