Description
Technical field
The invention belongs to modern pavement technique field, particularly the Road construction modified asphalt material is specifically related to the SBS modified emulsifying asphalt.
Background technology
Improve the modifying asphalt that asphalt performance obtains with polymkeric substance styrene-butadiene-styrene (being called for short SBS), bituminous viscosity is increased, elasticity increases, and improves bituminous high-temperature behavior and low-temperature performance.
Pitch is heated, make it have enough big flowability and enough low viscosity, prepare soap lye with emulsifying agent simultaneously, asphalt emulsification can be formed stable colloid by emulsifying device again, the preparation emulsified bitumen.But the evaporation residue softening temperature of common emulsified asphalt and SBR latex modified emulsified bitumen is lower, and high-temperature behavior is not satisfactory.
The SBS modifying asphalt has very high viscosity, causes the production of emulsified bitumen to become quite difficult, usually causes serious skinning, residual content severe overweight on the sieve, and stability of emulsion is poor, therefore, the infeasible saying of emulsified SBS modified asphalt is arranged in the industry.
Can reduce its viscosity although improve SBS modifying asphalt temperature, too high temperature might cause SBS degraded and ageing of asphalt on the one hand, make emulsifying device be difficult to bear on the other hand, be in particular in that pressure is excessive in the colloidal mill, and acid attack increases the weight of or the like.The unrestricted SBS consumption that reduces also can reduce asphalt viscosity, but asphalt performance can not get improving, and does not have the effect of modification.
Reduce asphalt high-temperature viscosity (common more than 135 ℃), domestic also have research, mentioned in interim " test and the evaluation of admixture Sasobit modifying asphalt " literary composition in 2003 05 as " China and foreign countries' highway ": the viscosity of the modifying asphalt of admixture Sasobit is higher than former state pitch in the time of 60 ℃, but after 100 ℃, the viscosity of modifying asphalt is lower than former state pitch on the contrary, and rising along with temperature, the amplitude that reduces also increases, this shows that this method can improve bituminous high-temperature behavior (raising permanent deformation resistance), simultaneously can improve asphalt workability (being easy to pave compacting).The volume of most of its properties-correcting agent of modifying asphalt all requires more than 4%, even more than 6%, just might increase substantially the bituminous softening temperature, and the Sasobit volume only is 3% just to have increased substantially the bituminous softening temperature, but this method only rests on the modifying asphalt application stage, is not applied to the emulsified modified asphalt field.
About the development of SBS modified emulsifying asphalt, the technology of using liquid SBS is arranged both at home and abroad.Liquid SBS all adopts import, and market is rare, cost an arm and a leg, so not adopt in a large number.Domestic liquid SBS also has research, but only is used to produce the SBS modifying asphalt, can not be used to produce modified emulsifying asphalt.As the Chinese patent of announcing on May 25th, 2005, the manufacture method of eu-bitumen properties-correcting agent (publication number is 1618862) discloses a kind of liquid SBS making method, solid SBS is dissolved in the organic solvent, make solid SBS become the solution shape, in this solution shape SBS, add tensio-active agent and water again, obtain the liquid SBS of emulsion form by emulsification method.But this method of manufacturing liquid SBS is more loaded down with trivial details, and liquid SBS contains more tensio-active agent, if produce emulsified bitumen with this liquid SBS, after adding this tensio-active agent of emulsifying agent, then tensio-active agent is too much, can cause emulsified bitumen defective, therefore domestic this liquid SBS is difficult to use in the production emulsified modified asphalt, and does not see that it is further studied and use in the modified emulsifying asphalt field.
At the current techniques background, SBS modified emulsifying asphalt production field faces two technical barriers: 1. how in high temperature (common more than the 135 ℃) viscosity that reduces the SBS modifying asphalt under the prerequisite that does not influence high temperature performance of asphalt (as softening temperature), thereby reduction emulsifying temperature? 2. how to reduce cost (promptly adding a small amount of SBS), significantly improve the high-temperature behavior of Asphalt Emulsion Evaporation Residue again?
Summary of the invention
The object of the invention provides a kind of SBS modified emulsifying asphalt.
