Description
Technical field
The present invention relates to a kind of complex ionic asphalt warm-mix agent and preparation method thereof, more particularly to a kind of anion-non-
Ion composite type pitch warm-mixing agent and preparation method thereof.
Background technology
The asphalt used in current road engineering is generally divided into two types according to construction temperature is mixed and stirred：Cold mixing is dripped
Blue or green compound CMA (Cold Mix Asphalt) and hot-mix asphalt mixture HMA (Hot Mix Asphalt).Cold-mix asphalt is mixed
Close material it is general using emulsified asphalt or liquid asphalt with gather materials mixed and stirred under normal temperature state, making, without to gathering materials and combining
Material is heated, and can so save mass energy.But cold-mix asphalt compound initial stage pavement performance is poor, it is difficult to meet public at a high speed
The requirement of the important engineerings such as road, Heavy Traffic road.Hot-mix asphalt mixture be most widely used, pavement performance it is the best
A kind of compound.But in hot-mix asphalt mixture production process, pitch is needed in 150~180 DEG C of high temperature bars with building stones
Mixed and stirred under part.Building stones, pitch are heated to temperature so high, mass energy is consumed.In addition in hot-mix asphalt mixture life
Substantial amounts of CO is generated during product2, flue dust and pernicious gas (CO, SO2、NOxDeng), not only pollute environment, and influence
Staff's is healthy.Meanwhile, mixing and stirring under hot conditions also result in the aging of pitch, reduce asphalt
Pavement performance.
Be environmental protection, energy saving, the middle and later periods nineties 20th century Europe and the country such as U.S. carried out warm mix drip
The research of blue or green compound WMA (Warm Mix Asphalt), the purpose is to pass through to reduce mixing and stirring and the temperature that paves for asphalt
Degree, reaches the energy consumption reduced in Process of Pitch Mixture Production, reduces CO2Deng gas and dust discharge amount, while ensureing warm mix
Asphalt has the pavement performance and construction workability essentially identical with hot-mix asphalt mixture.
At present, warm mix asphalt technologies mainly have three kinds of modes：One is to add one kind in pitch in advance to drop
Low pitch 135 DEG C of additives of viscosity, chemically angle changes the viscosity-temperature curve of pitch, so as to reduce mixing for pitch and building stones
And temperature, but the method can generally also reduce by 60 DEG C of viscosity of pitch and reduce the high-temperature stability of compound；Two is to use
Solid content emulsified asphalt higher, mixes and stirs at a temperature of 80~120 DEG C with building stones, and which is low compared with the temperature of hot asphalt by about 30
~50 DEG C；Three is while during tank is mixed and stirred in addition, because the presence of water makes asphalt foaming, reaching in mixing compound water and pitch
To viscosity reducing effect.If but the method amount of water is excessive, substantial amounts of vapor can be produced or cause bumping, if water is very few,
Foaming effect is bad.
CN102268189A discloses a kind of warm-mixed asphalt additive preparation method, and it is using one kind in dicyandiamide solution
The additive of organic silicon modified by polyether polymer composition.The additive is that the solvent of certain proportioning and alkoxy silane are added into three
In mouth flask, 80 DEG C are heated to；Add acid catalyst, base catalyst, the mixture of deionized water, 80 DEG C of reaction 90min of constant temperature；
100 DEG C are warming up to, condensing reflux 120min collects cut 55ml or so；Acid catalyst and quantitative polyethers are added in flask
In, intensification esterification 180min is vacuumized, condensing reflux 30min；Room temperature is cooled to, quantitative melamino-formaldehyde is added
Resin agitating is uniform；Appropriate base catalyst adjustment pH=8 or so is eventually adding, is got product.The addictive preparation method is complicated,
Repeatedly heat up charging and condensing reflux are needed, and is related to the esterification of long period and is vacuumized, and lack correlated performance
Verification method and instance data support that the excitant such as acid base catalysator that the additive is used in addition and toxicity are larger, easily cause
Harm and environmental pollution.
CN101899218A discloses a kind of asphalt warm-mix agent and its mixing preparation method for material.The warm-mixing agent is necessarily to match somebody with somebody
The alkyl amine of ratio, amide-type cationic surfactant mix with water, add quaternary cationic surfactant, then add
Enter calcium chloride, it is well mixed to obtain final product asphalt warm-mix agent.The preparation method of the asphalt is to add to pre- pitch and mineral aggregate
If temperature, pitch is first added in mixing machine, 3~5 after addition second are initially added into warm-mixing agent, and warm-mixing agent the addition time
It is less than 10 seconds, and requires to complete the addition of warm-mixing agent, 5~10 seconds after the completion of pitch addition before pitch addition is completed
Addition mineral aggregate.Three kinds of different cationic surfactants are added in the warm-mixing agent, antistripping can be to a certain extent played
Effect, but described viscosity reduction and the effect of foaming lack basis；Requirement of the preparation process of the asphalt for the time
It is excessively harsh, accurate manipulation is difficult in practical operation especially commercial Application.
