Abstract
The invention discloses a high-performance hybrid modified asphalt emulsion which comprises 60-75% of modified asphalt, 1-5% of composite emulsifier, 0.05-0.2% of emulsifying aid and 25-40% of water. The preparation method comprises the following steps: preparing the high-performance modified asphalt, and adding 4-8% of the modifier; compounding the specific modified asphalt emulsifier; and heating the high-performance modified asphalt to 70-200 DEG C, heating the water-soluble temperature of the emulsifier to 60-90 DEG C and the like. The crosslinking agent is a special crosslinking agent capable of crosslinking the modifier in the dewatered state at room temperature, and the addition amount is 4%. The properties of the film formed by the dewatered modified asphalt emulsion are greatly enhanced, i.e. the softening point reaches at least 80 DEG C, the low-temperature ductility is at least 40cm when the temperature is 5 DEG C, the elastic recovery rate is up to 92% or above, the average binding force is 1.01 MPa, and the organic matter-inorganic matter composite stabilizer accounts for 0.05-0.2%, thereby effectively solving the problem of room-temperature stability in the modified asphalt emulsion; and thus, the modified asphalt emulsion has favorable long-term storability.
