| titleOfInvention | Preparation method of polyurethane modified carbon black particles |
| abstract | The invention discloses a preparation method of polyurethane modified carbon black particles, which comprises the following steps: pouring PVP into a three-neck flask, dissolving the PVP in hot water, cooling to normal temperature, adding Tween-80, stirring and emulsifying, adding CB, stirring and carrying out ultrasonic treatment for 25-35min, dropwise adding IPDI, stirring for 15-25min, slowly dropwise adding PEG and triethylene diamine into the reaction solution, stirring and reacting for 40-50min, adding ethylene glycol, heating to 60-70 ℃, stirring and reacting for 3-4h, washing after the reaction is finished, extracting the modified particles for 74-76h by using a Soxhlet extractor, repeatedly washing the extracted particles with acetone, absolute ethyl alcohol and deionized water in sequence until the filtrate is neutral, and drying to obtain the PVP-free modified particle. The method has the advantages of no addition of an auxiliary agent, simple process and equipment, no pollution, excellent dispersibility of the prepared polyurethane modified carbon black particles in a matrix, stable dispersion and the like. |
