| titleOfInvention | A kind of chemically modified petroleum asphalt and preparation method thereof |
| abstract | The invention belongs to the technical field of petrochemical industry, in particular to a chemically modified petroleum asphalt and a preparation method thereof. The steps include shearing and dispersing petroleum asphalt, emulsifier, polystyrene sulfonate and water to obtain petroleum asphalt emulsion; and then removing water after constant temperature electrolysis of the petroleum asphalt emulsion under the protection of inert gas to obtain electrolyzed petroleum Asphalt; after mixing the electrolytic petroleum asphalt, styrene-butadiene-styrene block copolymer and chloroform, heat-retaining ball milling reaction, and then removing chloroform. The petroleum asphalt chemically modified by the present invention has excellent storage stability. |
