BITUMEN EMULSION AND PRODUCTION THEREOF Russian patent published in 2005 - IPC

FIELD: building industry, in particular production of bitumen emulsions for roof claddings, hydraulic insulating materials, binder for organomineral mixtures and cold blacktops.

SUBSTANCE: claimed emulsion contains (mass %) bitumen 47-50; mixture of cotton oil secondary reprocessing product with flotogoudron in ratio of (40-70):(60-30) 3.0-5.0; sodium hydroxide 0.6-1.0 or potassium hydroxide 0.3-0.8; and balance: water. Claimed emulsion is obtained by preparation of emulsifier from part of mixture of cotton oil secondary reprocessing product with flotogoudron (namely slop from distillation of vegetable oil fatty acids), when agitation with preheated sodium hydroxide or potassium hydroxide aqueous solution up to full mixture dissolution to produce finished emulsifier aqueous solution followed by introducing when agitation of heated bitumen being mixed with residual mentioned above mixture.

EFFECT: bitumen particles with decreased surface tension and coalescence; more active interaction between bitumen and emulsifier aqueous solution; stable emulsion with prolonged storage time.
