METHOD OF PRODUCING BITUMEN-RUBBER BINDER Russian patent published in 2014 - IPC C08L95/00 C08L21/00 C08J11/00

Abstract RU 2529552 C1

FIELD: chemistry.

SUBSTANCE: binder is obtained by mixing petroleum bitumen, while heating, with 5.0 wt % rubber taken in the form of a solution thereof in an organic solvent containing no more than 30 wt % oil-resistant rubber, wherein the organic solvent used is a fraction of liquid products of pyrolysis of car tyres which boils at temperature higher than 200°C.

EFFECT: wider range of organic solvents for oil-resistant rubber used to produce bitumen-rubber binder, and improved economic parameters of the process owing to use of an organic solvent obtained from waste car tyres, improved processing properties.
