Description
Technical field
The present invention relates to field of road traffic, and in particular to a kind of high-performance asphalt emulsifier and preparation method thereof.
Background technology
The dark brown complex mixture that pitch is made up of the hydrocarbon and its non metallic derivatives of different molecular weight.
Asphalt material has the characteristic such as good cohesiveness, impermeability, insulation, corrosion-resistant, can be widely used for road traffic, building,
The industries such as paint, wherein road asphalt account for 75% or so that pitch uses total amount.Due to being solid under most of pitch normal temperature,
So traditional application method of road asphalt is that pitch first is heated into flowable state, then it is used in combination again with other aggregates.But
With greatly increasing for road asphalt usage amount, it has been found that the various shortcomings of heated asphalt to flowable state, construction is inconvenient, ring
Border is polluted, energy expenditure is excessive, the uneasy congruence of production, and then emulsified asphalt starts to occur and is applied.Emulsified asphalt be
Pass through mechanical dispersion under emulsifying agent effect, make pitch be dispersed in water to form emulsion with tiny graininess, and then can be with
Realize normal temperature application.This technology can save the heating stepses before construction, reduce fuel usage amount, also improve generation effect
Rate, reduces environmental pollution.
The critical material of emulsified asphalt is asphalt emulsifier.The emulsifying agent of early stage is mainly anion emulsifier, but due to
Bitumen particle is negatively charged in anionic emulsifying agent emulsion, and most of building stones are also negatively charged, cause electric charge to repel each other, make pitch
Particulate can not be well adhered to stone surface, and influence is used.Cause gradually to be replaced by the emulsified asphalt of cationic.It is wide at present
The general cationic asphalt emulsifier used mainly has following five kinds：(1) quaternary ammonium salt；(2) alkyl amine；(3) amide groups amine；
(4) imidazolines；(5) lignin amine.
Although cationic emulsified asphalt has reached construction requirement, still some problems of generally existing, such as product quality
Unstable, emulsifying agent usage amount is excessive, and this considerably increases generation and construction cost.Therefore a kind of high performance pitch is prepared
Emulsifying agent is particularly important.

The general structure of described fatty amidogen ether is as follows：
Wherein, X+Y=4~6, R1For octadecyl；
Described fatty acid amide is that obtained by oleic acid and polyethylene polyamine reaction, general structure is as follows：
Wherein, m=2,3 or 4, R2For heptadecene base；
Described auxiliary agent 1 is primary octadecylamine or 16 primary amine；
Described auxiliary agent 2 is sodium chloride, calcium chloride, ammonium chloride, sodium sulphate, the one or more of magnesium sulfate.
A kind of described high-performance asphalt emulsifier, its preparation method is：
1) various raw materials are weighed by formula rate；
2) fatty amidogen ether, fatty acid amide are once added into reactor, constant temperature stirs, temperature is 100 DEG C；
3) above-mentioned material is cooled to less than 100 DEG C, adds auxiliary agent 1 and auxiliary agent 2, continued to stir, be completely dissolved mixing, i.e.,
Obtain emulsifying agent finished product.
It is an advantage of the current invention that the invention discloses a kind of method for preparing asphalt emulsifier, the emulsifying agent is former
Cheap, the prepared asphalt emulsifier steady quality of material, emulsifiability is excellent, can reduce the usage amount of emulsifying agent, and system
Standby asphalt emulsion is well-behaved, meets the examination criteria of JTG E20-2011 test methods.
The above of embodiment by the following examples again to the present invention is described in further detail, but
It is not limited only to following embodiment.The present invention includes above-mentioned technological thought, while according to ordinary skill knowledge and usual
Various replacements or change that means are made, all should be included within the scope of the invention.
