METHOD OF PREPARING CATIONIC ADHESIVE ADDITIVE FOR BITUMENS Russian patent published in 2003 - IPC

Abstract RU 2206584 C1

FIELD: petroleum processing and petrochemistry. SUBSTANCE: objective of invention is improvement of adhesive properties of bitumens to surface of mineral material having both acid and basic nature, in particular for use in road building and for airdrome runways. For that, invention provides adhesive additive, which is prepared by reaction of functionally substituted hydrocarbons with amines at heating. In particular, the former are chloroparaffins of general formula C_nH_2n+2-xCl_x, where n=10-30 and x=1-7, and the latter amines of general formula H₂N(CH₂CH₂NH)_yH, where y > 1, at substituted hydrocarbons-to-amines ratio (2.3-5.6):1. EFFECT: considerably increased coefficient of adhesion of bitumen with mineral material surface. 1 tbl
