METHOD OF PREPARING CARBON-CONTAINING DISPERSION Russian patent published in 2008 - IPC C08J3/02 C08J11/04 C08K3/04 C08L21/00 

FIELD: rubber industry.

SUBSTANCE: invention provides a method of preparing carbon-containing dispersion that may be used in manufacture of filled liquid rubbers as well as when preparing additives for rubber compounds. Method is accomplished by mixing liquid rubber waste with molecular mass 500 to 20000 and content of solvent 0 to 20% with extender, namely spent activated carbon. Weight ratio of binder to extender varies between 100:33 and 100:200. Preparation of dispersion and processing are performed on extruder at 25 to 180°C.

EFFECT: improved physicomechanical characteristics of vulcanizates obtained by using dispersion of carbon-containing extender and eliminated harmful environmental effect of rubber waste consumed in preparation of dispersion.
