| titleOfInvention | A kind of detection method based on modifier incorporation in the modified bitumen of dead-stop titration |
| abstract | The invention discloses a kind of detection method based on modifier incorporation in the modified bitumen of dead-stop titration, the method first prepares the modified asphalt solutions of known modifier incorporation and the modified asphalt solutions of the unknown modifier amount of participating in be measured; Add unsaturated link addition agent treated; Add liquor kalii iodide process again; Carry out redox titration with hypo solution again, and determine the volume of consumed hypo solution by dead-stop titration; The sodium thiosulfate volume utilizing the solution of the modified bitumen of known incorporation to consume and volume drawing standard curve; Modifier incorporation in modified bitumen to be measured is calculated by the sodium thiosulfate volume consumed of volume to be measured and typical curve.The method effectively can overcome the impact that the precipitation that produces in pitch dark-background and titration process is analyzed conventional titration, quick and precisely detects the incorporation of modifier in modified bitumen, for modified bitumen production and processing quality control provides safeguard. |
