Description
Technical field
The invention belongs to traffic ground surface material technical field, be specifically related to a kind of method of utilizing coal directly-liquefied residue to prepare modifying asphalt.
Background technology
As everyone knows, in coal system oil tech, direct coal liquefaction technology has begun heavy industrialization in China to be used, but the processing of the residue that produces in the DCL/Direct coal liquefaction process but still is not well solved.
Because the world energy sources crisis, oil and related products price thereof rise steadily, and cause asphalt price also to improve constantly, and also make the Road construction material cost constantly increase.In order to reduce the use cost of petroleum pitch, people turn to the utilization of coal directly-liquefied residue to sight, and this is because coal directly-liquefied residue contains bituminous matter and oil content, and is similar a bit to pitch on the composition, have to replace or the possibility of modified oil pitch.
Chinese patent application (application number: 200610012547.9), a kind of road asphalt modifier and application method thereof are disclosed, coal directly-liquefied residue is crushed to below 100 orders exactly, with pitch be that 5-30% mixes 100-250 ℃ of scope by the weight ratio that coal directly-liquefied residue accounts for modifying asphalt, the modifying asphalt that obtains.Yet, research (king stockaded village rosy clouds are arranged again, Yang Jianli, Liu Zhenyu. coal directly-liquefied residue is to the preliminary assessment of modifying road asphalt effect. the chemistry of fuel journal, 2007,35 (1): the modifying asphalt that is obtained when 109-1120) having only interpolation less than the coal directly-liquefied residue of 7% weight ratio in showing just has use value, and after residue content improves again, because the pitch embrittlement, low-temperature performance is bad, is difficult to satisfy the pavement performance requirement.
Chinese patent application (application number 200710178082.9) discloses a kind of method for preparing modifying asphalt with coal directly-liquefied residue, the matrix pitch of the molten state of the coal directly-liquefied residue of 150-280 ℃ molten state and 100-180 ℃ is stirred under 150-280 ℃, form melts, thereby obtain modifying asphalt, this method distinct issues are matrix pitch experience high temperature when mixing, very easily cause the aging of matrix pitch, and because the coal directly-liquefied residue volume that the preparation modifying asphalt uses is little, this is concerning digesting a large amount of coal directly-liquefied residues, and its effect is too little.
Summary of the invention
The object of the present invention is to provide a kind of method of utilizing coal directly-liquefied residue directly to prepare modifying asphalt, this method is simple, and production cost is low, controllability is strong, and the performance of modified bitumen of preparation meets every index of modified oil pitch.
In order to realize above-mentioned technical assignment, the present invention adopts following technical scheme to be achieved.
A kind of coal directly-liquefied residue composite modified asphalt, it is to be made according to weight percent by following raw material: coal directly-liquefied residue: 70～80%, oil content: 15～30%, colloid: 5～10%, the per-cent sum of raw material is 100%.
Described coal directly-liquefied residue is that the softening temperature of discharging from vacuum distillation apparatus after the DCL/Direct coal liquefaction is not higher than 180 ℃, and solids content is no more than the coal residue of 50% weight percent; Described oil content is wherein one or more mixtures of phthalate, epoxy compounds, naphthenic oil, fatty hydrocarbon ils, aromatic hydrocarbon oil, turps, Stockholm tar, tung oil, citrate, aliphatic dicarboxylic acid ester, monocarboxylate, trimellitate or phosphoric acid ester; Described colloid is wherein one or more mixtures of Gum Rosin, coumarone indene resin, novolac resin, low-molecular-weight polyamide resin, vinyl acetate resin, carbon 5 petroleum resin or carbon 9 petroleum resin.
The preparation method of above-mentioned coal directly-liquefied residue composite modified asphalt, can follow following steps: choose coal directly-liquefied residue according to weight percent: 70～80%, oil content: 15～30%, colloid: 5～10% as raw material, and at normal temperatures raw material is mixed, be warming up to 90～160 ℃ then, obtained modified asphalt material in 30～45 minutes afterwards through high speed dispersor high speed dispersion, mixing.
Coal directly-liquefied residue of the present invention directly prepares the method for modifying asphalt, and method is simple, production cost is low, workable, and the performance of modified bitumen of preparation all can meet every index of modified oil pitch.This method has significant values to the rational and efficient use of coal directly-liquefied residue, and the while is significant equally for saving Road construction cost, energy-conserving and environment-protective.
Modified asphalt material according to the present invention's preparation can be used as the road surface of motorway or the pavement material of bridge floor in addition, and wide market application prospect is all arranged.
Embodiment
It is according to three principles that chemical composition bituminous matter, oil content and colloid play a role separately that constitute petroleum pitch that the present invention utilizes coal directly-liquefied residue to prepare modifying asphalt, i.e. the contour warm nature energy of bituminous matter decision bituminous softening temperature; Oil content decision bituminous denseness and pliability have very big influence to the bituminous ductility; Colloid is given pitch plasticity-, flowability and agglutinating value(of coal), and bituminous ductility is also had very big influence.Through discovering, owing to lack oil content and glial component in the conventional pitch in the coal directly-liquefied residue, in coal directly-liquefied residue, add an amount of oil content and colloid, can be prepared into modifying asphalt.This method realizes replacing petroleum pitch, widely applies coal directly-liquefied residue in constructing road, can turn waste into wealth, and has widened the coal directly-liquefied residue range of application, is worth for realizing recycling economy performance certain economic.
