Description
Technical field
The present invention relates to a kind of warm mix polymer modified asphalt mixtures and preparation method thereof, belong to petroleum industry and basis
Technical field of material chemistry.
Background technology
The asphalt used in previous road engineering is generally divided into two types according to mix construction temperature：Cold mixing drips
Green mixture CMA (Cold Mix Asphalt) and hot-mix asphalt mixture HMA (Hot Mix Asphalt).Cold-mix asphalt is mixed
Material is closed generally using emulsified asphalt or liquid asphalt and gather materials mix, making under normal temperature state, without to gathering materials and combining
Material is heated, and can save mass energy in this way.But cold-mix asphalt mixture early strength is relatively low, it is difficult to it is public to meet high speed
The requirement of the important engineerings such as road, Heavy Traffic road.Hot-mix asphalt mixture be widely used, the good mixing of pavement performance
Material.But in hot-mix asphalt mixture production process, pitch needs the mix under 150 ~ 180 DEG C of hot conditions with building stones.No
Only consume a large amount of energy, and will produce in hot-mix asphalt mixture production process a large amount of flue dust and CO2, CO, SO2,
The pernicious gases such as NOx, flammable organic gas, not only pollute environment, but also influence the health of staff, meanwhile,
Mix under hot conditions also easily causes pitch and heat ageing occurs, and reduces active time of the pitch on road surface, shortens pitch
The service life on road surface.
It is energy saving for environmental protection, extend the bituminous paving service life, the developed countries such as later stage the 1990s America and Europe open
The research of Warm-Mix Bitumen Mixture WMA (Warm Mix Asphalt) is opened up.The purpose is to by reducing mixing for asphalt
Temperature is closed, the energy consumption reduced in Process of Pitch Mixture Production is reached, reduces dust and harmful gas emission, while ensureing temperature
Mix workability of the asphalt with the pavement performance essentially identical with hot-mix asphalt mixture and construction.
There are mainly three types of modes for warm-mixed asphalt technology：First, the higher emulsified asphalt of evaporated residue content is used, 80
DEG C ~ 120 DEG C at a temperature of with building stones mix, which is about 30 DEG C ~ 50 DEG C low compared with the temperature of hot asphalt；Second is that in mixing mixture
When water（Or the aqueous solution of surfactant）It is added simultaneously in mix tank with pitch, due to the presence of water, makes asphalt foaming, reach
To viscosity reducing effect.But above two method will produce a large amount of vapor, easily causes equipment corrosion, mountain flour also frequently occurs
Conglomeration even causes mixing equipment blockage problem, makes troubles to production.Further, since remaining non-volatile moisture be retained in it is mixed
It closes in material, mixture initial performance can be influenced.The third method is that warm-mixing agent is added in pitch in advance, then takes and leads to
The same mode of production of normal hot-mix asphalt mixture, it is easy to operation, it is easy to be received by production unit.This kind of method passes through pre-
Warm-mixing agent is first added in pitch, is reduced the high temperature viscosity of pitch, is changed the viscosity-temperature curve of pitch, to reduce pitch
With the mix temperature of building stones, reach warm mix effect.But presently used warm-mixing agent is while reducing asphalt high-temperature viscosity, usually
Also the reduction that can cause 60 DEG C of viscosity of pitch, makes the high-temperature stability of asphalt incur loss；Or on the contrary, not reducing
When 60 DEG C of viscosity, the loss of pitch ductility can be caused, to reduce the cryogenic property of pitch.In short, presently used temperature
It mixes agent and is while so that pitch is reached warm mix effect, be high-temperature behavior to lose pitch or cryogenic property as cost.
CN201010233760.9 use alkylamine, amide, quaternary cationic surfactant and calcium chloride, water for
Warm-mixing agent is made in raw material.It is called " asphalt warm-mix agent " with it, is exactly a kind of aqueous solution of surfactant in fact.Preparing pitch
It is added in pitch when mixture, then adds building stones again.With when being stirred together with pitch, this aqueous surfactant solution
It can foam after heated, drive pitch also to foam, play warm mix effect.But due to foaming effect, bumping is easily caused, operation is not
Just, vapor is also easy to cause equipment corrosion and mountain flour conglomeration occluding device, not susceptible to user acceptance.
CN200910069522.6 discloses a kind of warm-mixed asphalt additive and preparation method thereof, the additive be pass through by
Deionized water is added in the polyvinyl alcohol water solution being made into advance, then sequentially adds rosin quaternary ammonium salt, aromatic hydrocarbon quaternary ammonium salt
Emulsifier, aliphatic hydrocarbon quaternary ammonium salt emulsifier, nonionic surface active agent, stirring and dissolving, then the polyacrylamide that will be made into advance
Amine aqueous solution and triethanolamine are added, and it is finished product to mix to after being uniformly dissolved.The additive can be substantially reduced pitch
Mix temperature, asphalt items pavement performance index also comply with requirement, but the additive not only complicated component, increase
The difficulty and cost of preparation, are unfavorable for practical application.Although and be added to the high temperature viscosity that pitch can be reduced in pitch,
Simultaneously also bring along negative effect reduce pitch softening point and 60 DEG C of viscosity can make to have lost high-temperature stability
Road surface is easy to happen track or gathers around packet.
CN201110158370.4 discloses a kind of warm-mixed asphalt additive and preparation method thereof, is adopted in dicyandiamide solution

Component includes vegetable wax, animal wax, mineral wax, amide waxe, oxidized wax etc., resin Composition include propolis and Petropols such as
Tall oil pitch, pine tar pitch, rosin, phenolic resin etc..Wax component and resin Composition play Efficient Adhesive Promotion, with make up due to
The loss of asphalt viscosity caused by above-mentioned surface active agent composition.Component used in the patent is excessive, although can utilize wherein
Surface active agent composition lubricating action, play warm mix effect, but be easily reduced 60 DEG C of viscosity of pitch, influence pitch
High-temperature stability can also reduce the caking property of pitch and building stones.Although the resin Composition such as rosin, phenolic resin etc. of addition can be more
The loss of the asphalt viscosity caused by above-mentioned surface active agent composition is mended, but the compatibility of resin Composition and pitch is bad, it is long
Time easily causes pitch layering when storing, simultaneously because its hardness is higher, can only improve the high-temperature behavior of pitch, and cannot change
The cryogenic property of kind pitch, easily causes pitch cold cracking, can also influence the caking property of pitch.
CN201310174417.5 is prepared for asphalt warm-mix agent using amides, aromatic naphtha, binder component.Acyl therein
Amine is ethylene double one or both of oleamides and erucyl amide, and the mix temperature of pitch is reduced using its lubricity；
Binder is dimethylamino propylamine, N- aminoethylpiperazines, diethylenetriamines, trien, tetren
One or more of.Method is will to be first uniformly mixed after amides and aromatic naphtha heating and melting, then adds binder, then stir
It mixes uniformly mixed.It is cooled to later thick, is granulated, dried, crushed, be sieved, obtain the graininess that grain size is less than 20 mesh
Substance, as asphalt warm-mix agent.Amides are while reducing asphalt mixing temperature in the patent, it is easy to reduce the 60 of pitch
DEG C viscosity, influences the high-temperature stability of asphalt, can also reduce the caking property of pitch.Although taking doing for addition binder
Method, " promote the caking property of pitch and building stones or eliminate adverse effect of the amide substance for pitch and building stones caking property ",
But heating temperature is higher when in use for these binders, will produce a large amount of noxious vapors, and the smell is awful, influences environment, damage
The health of operating personnel.
