Paragraph 0114-0116; 0120; 0132; 0134; 0139, (2018/04/26)
The invention discloses a quaternary ammonium salt type hydroxypropyl sodium phosphate asphalt emulsifier and a preparation method thereof. The asphalt emulsifier is prepared from octadecylamine, isopropanol, epoxypropane, epoxy chloropropane and sodium dihydrogen phosphate in a molar ratio of 1 mol:(4.00-9.00) mol:(4.00-4.20) mol:(1.00-1.15) mol:(1.50-1.73) mol, or is prepared from octadecylamine, isopropanol, epoxypropane, epoxy chloropropane, trisodium phosphate and hydrochloric acid in a molar ratio of 1 mol:(4.00-9.00) mol:(4.00-4.20) mol:(1.00-1.15) mol:(1.30-1.50) mol:(1.40-1.61) mol. The synthetic raw materials of the asphalt emulsifier are easy to obtain, the production cost is low, the process is simple, and a high-temperature reaction is not needed. Various types of asphalt canbe emulsified, the prepared asphalt is fine, even and good in storage stability, and cationic emulsified asphalt can be prepared.

-
Paragraph 0103 - 0105, (2018/03/01)
The invention discloses a secondary amide quaternary ammonium salt type hydroxypropyl sodium sulfonate asphalt emulsifier and a preparation method thereof, wherein the secondary amide quaternary ammonium salt type hydroxypropyl sodium sulfonate asphalt emulsifier is prepared from the following raw materials octadecylamine, an alcohol solvent, N-hydroxymethyl acrylamide, epichlorohydrin and sodium bisulfite according to a molar ratio of 1:(4.00-9.00):(2.00-2.10):(1.00-1.15):(1.05-1.25), and the alcohol solvent is ethanol, methanol or isopropanol. According to the present invention, the preparation method has advantages of easily available raw material, low production cost, simple process and no requirement of high temperature reaction; and the obtained secondary amide quaternary ammonium salt type hydroxypropyl sodium sulfonate asphalt emulsifier can emulsify a variety of different types of asphalts, and can be used for preparing cationic emulsified asphalts, and the emulsified asphalt prepared from the secondary amide quaternary ammonium salt type hydroxypropyl sodium sulfonate asphalt emulsifier has advantages of fine and uniform property and good storage stability.
