| titleOfInvention | Plant oil base asphalt modifier, the modified pitch containing the modifying agent and its preparation |
| abstract | The invention discloses a kind of vegetable oil based polyurethane modifying agent, modified pitch and preparation method thereof.The vegetable oil based polyurethane modifying agent is to replace petroleum-based polyols as polyhydroxy component by dehydrated plant oil polyalcohol, it is added in polyisocyanate component at 25~35 DEG C, isocyanate index R is between 1.4~1.8,40~50 DEG C are warming up to after adding, 1.5~3h of insulation reaction, the solvent for accounting for the 5-50% of reactant total volume is added in reaction process with regulation system viscosity, a series of vegetable oil based polyurethane performed polymer of different condensation levels is made.It controls prepolymer and synthesizes degree, added to be made in matrix pitch and contain the vegetable oil based polyurethane modified pitch.Asphalt modifier viscosity provided by the invention is low, good fluidity, is easy to disperse in pitch, shearing process required temperature is low, and the time is short, and prepared vegetable oil based polyurethane modifying agent is environmentally protective renewable, and gained modified pitch ingredient is simple, high temperature performance is excellent. |
