Abstract
A process for preparing the modified emulsified asphalt is prepared from basic asphalt emulsifier and latex as modifier through mixing latex with emulsifier, stirring, heating, mixing with asphalt and stirring. Its advantages are excellent performance, high construction efficiency of road pavement, and long service life.
Description
Technical field
The present invention relates to a kind of modified emulsifying asphalt and preparation method thereof, belong to asphalt emulsification and modification
Technical field.
Background technology
With the emulsified bitumen is the Construction Technique for Slurry Seal Coat of binding material, has applied range, and construction is convenient, energy-saving and cost-reducing, reduces and pollutes, and prolongs plurality of advantages such as construction time.But because single matrix pitch, shortcomings such as viscosity low, snappiness difference strong to temperature sensitivity have restricted applying of Slurry Seal Technology.
In view of the outstanding advantage of Construction Technique for Slurry Seal Coat, applying of it is imperative, but problem is how to improve the performance of emulsified bitumen.Promptly emulsified bitumen is carried out modification, makes it have excellent low temperature splitting resistance, high-temperature stability, extremely strong cohesive force and superior recovery of elasticity etc., with the road of satisfying different grades with requiring.
Summary of the invention
The purpose of this invention is to provide a kind of every technical indicator and all be better than common emulsified bitumen, can satisfy the road use properties, prolong the preparation method of the modified emulsifying asphalt in road work-ing life.
The present invention is the preparation method of modified emulsifying asphalt, comprise matrix pitch, emulsifying agent, properties-correcting agent latex, it is characterized in that earlier with properties-correcting agent latex and emulsifier solution thorough mixing evenly after, be heated to certain temperature, pass through the mulser mixing and emulsifying with matrix pitch again, behind the mechanical stirring froth breaking, make modified emulsifying asphalt.
Described emulsifying agent and the add-on of properties-correcting agent latex in matrix pitch with the weight percent meter of matrix pitch, are respectively 1～10% and 1～50%.
Described emulsifying agent can be quaternary ammonium salts or wooden amine, amide group polyamines class, imidazolines etc.Described quaternary ammonium salts can comprise octadecyl trimethyl ammonium chloride, cetyl trimethylammonium bromide; Described wooden amine can comprise chlorination 2 hydroxyls-3-xylogen propylidene trimethyl ammonium, wooden amine; Described amide group polyamines class can comprise N-aminoethyl acid amides, alkylamidoalkyl polyamines; Described tetrahydroglyoxaline can comprise 1-aminoethyl-2-heptadecyl tetrahydroglyoxaline-2-hydrochloride, 1-aminoethyl-second-heptadecyl tetrahydroglyoxaline.
Described properties-correcting agent latex can be styrene-butadiene latex or polychloroprene latex, B-S-B latex, ethane-acetic acid ethyenyl polymer latex etc.
Also can add stablizer in the described emulsifying agent, its add-on can be the 0.01-5% of matrix pitch weight.Described stablizer can be chlorination (FeCL
3) or magnesium chloride (MgCL
2), ammonium chloride (NH
4CL), calcium chloride (CaCL
2), polyvinyl alcohol, Xylo-Mucine, methylcellulose gum, gelatin etc.The adding of stablizer can improve the package stability of modified emulsifying asphalt.
Also can add additives such as entry or hydrochloric acid in the described emulsifying agent.The adding of additive such as water or hydrochloric acid mainly is to improve the reactive behavior of emulsifying agent and increase package stability.
The mixing temperature of described emulsifying agent and properties-correcting agent latex can be 50-95 ℃.
But the emulsifying temperature in the described emulsification process is 130-170 ℃.
The prepared modified emulsifying asphalt of the present invention compared with prior art has following outstanding advantage and positively effect:
1. the emulsified modified asphalt excellent property is applicable to the little table punishment of slurry seal;
2. when pavement maintenance, can shorten and close traffic time, improve execution conditions, improve operating efficiency;
3. be used for maintenance, maintenance road surface effect is obvious.
Embodiment
The preparation method of modified emulsifying asphalt of the present invention is water-soluble emulsion process, and its specific operation process is as follows:
1, materials such as quantitative emulsifying agent, properties-correcting agent latex, stablizer, water are added mixing tank, fully mix, temperature is controlled at 60-95 ℃, makes emulsifier content accounts for 1-20% at 1-10%, latex latex emulsion.
2, when asphalt temperature reaches 130-170 ℃ and latex emulsion in (1-4): 1 ratio simultaneously by the emulsifying mill mixing and emulsifying after make modified emulsifying asphalt behind the mechanical stirring froth breaking.
