Abstract
A process for preparing the modified emulsified asphalt for road pavement includes such steps as proportionally adding latex as modifier to basic asphalt, stirring, proportionally mixing with emulsifier, stirring and defoaming. Its advantages are high performance, high construction efficiency of road, and long service life.
Description
Technical field
The present invention relates to a kind of preparation method of modified emulsifying asphalt, belong to asphalt emulsification and modification technology 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 a kind of preparation method of modified emulsifying asphalt, comprise matrix pitch, emulsifying agent, properties-correcting agent latex, it is characterized in that earlier properties-correcting agent latex directly being added in the matrix pitch thorough mixing evenly after, pass through the mulser mixing and emulsifying with emulsion 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 properties-correcting agent latex and matrix pitch can be 130-170 ℃.
Emulsifying temperature in the described emulsification process can be 50-95 ℃.
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 the molten method of drop, and its specific operation process is as follows:
1, when the matrix pitch temperature reaches 120-170 ℃, with properties-correcting agent latex input wherein, through fully stirring the solution of making homogeneous, wherein properties-correcting agent latex content 1-50% (with the bituminous weight percent meter).
2, materials such as quantitative emulsifying agent, stablizer, water are added mixing tank, fully mix, temperature is controlled at 50-95 ℃, makes emulsifier content at 1-10%.
3, pitch latex and emulsion are made modified emulsifying asphalt after by the mulser mixing and emulsifying.
