US Patent:

6540822, Apr 1, 2003

Filed:

Mar 20, 2001

Appl. No.:

09/812318

Inventors:

Julia Mary Wates - Chicago IL
Alan James - Naperville IL

Assignee:

Akzo Nobel N.V. - Arnhem

International Classification:

B01F 1728

US Classification:

106277, 106283, 516 43, 516 45, 516914, 516916

Abstract:

A method of emulsifying asphalt using a polyamine polybetaine, preferably a dibetaine, as an emulsifier or co-emulsifier and an emulsion of asphalt, water and a polybetaine, preferably a diamine dibetaine. The advantages of using a polyamine polybetaine as an emulsifier or co-emulsifier include its ability to provide superior cationic and anionic emulsions, and slow-setting emulsions at low use levels, and the excellent adhesion of the cured asphalt film.

International Classification:

C11D 3/12
C11D 1/825
C11D 1/94
C11D 1/835

US Classification:

510438

Abstract:

The present invention relates to an aqueous composition comprising three components. The first component is a primary detergent, non-ionic surfactant with a critical packing parameters (CPP) of ≧0.95. The second component is a inorganic particle whose surface has been modified to improve stability. The third necessary component is a secondary surfactant with a CPP of ≦0.85. The secondary surfactant can function to improve the overall cleaning performance, the streaking performance and provide overall formulation stability.

US Classification:

106277, 516 43

Abstract:

A method of emulsifying asphalt using a polyamine polyoxide, preferably a diamine dioxide, as an emulsifier or co-emulsifier and an emulsion of asphalt, water and a polyamine polyoxide, preferably a diamine dioxide. The advantages of using a polyamine polyoxide as an emulsifier or co-emulsifier include its ability to provide superior cationic and anionic emulsions, and slow-setting emulsions at low use levels, and the excellent adhesion of the cured asphalt film.
