Abstract
A process for preparing modified emulsified asphalt includes such steps as directly adding the latex of modifier to the asphalt matrix, mixing, emulsifying, mechanically stirring and defoaming. The addition amount of the emulsifier and the modifier latex in the matrix asphalt is 1-10% and 1-50% respectively by weight percentage of the matrix asphalt. The emulsified modified asphalt prepared by the invention has excellent performance, various technical indexes are superior to those of common emulsified asphalt, the road use performance can be met, the service life of the road is prolonged, and the emulsified modified asphalt is suitable for slurry seal micro-surfacing treatment; when the method is used for pavement maintenance, the traffic closing time can be shortened, the construction condition is improved, and the construction efficiency is improved.
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, again with emulsion by the mulser mixing and emulsifying, behind the mechanical stirring froth breaking, make change 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 is quaternary ammonium salt or wooden amine, amide group polyamines class, imidazolines etc.; Described properties-correcting agent latex is styrene-butadiene latex or polychloroprene latex, B-S-B latex, ethane-acetic acid ethyenyl polymer latex etc.; The mixing temperature of described properties-correcting agent latex and matrix pitch is 130-170 ℃; Emulsifying temperature in the described emulsification process is 50-95 ℃.
Described quaternary ammonium salt can comprise octadecyl trimethyl ammonium chloride, cetyl trimethylammonium bromide; Described wooden amine can comprise chlorination 2 hydroxyls-3-xylogen propylidene Trimethylamine, wooden amine; Described amide group polyamines class can comprise N-aminoethyl acid amides, alkylamidoalkyl polyamines; Described imidazolines can comprise 1-aminoethyl-2-heptadecyl tetrahydroglyoxaline-2-hydrochloride, 1-aminoethyl-second-heptadecyl tetrahydroglyoxaline.
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 iron(ic) chloride (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 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.
