Description
Technical field
The invention belongs to resource recycling and asphalt material technical field, and in particular to a kind of Ergol is got a foothold mixed
Close modified pitch.
Background technology
In recent years, with the fast development of China's communication, highway construction is advanced by leaps and bounds, it is necessary to which substantial amounts of road is dripped
It is blue or green.Most of road asphalt is using stability, the preferable asphalt of plasticity, but petroleum resources day are becoming tight, international crude petroleum
Price constantly rises, and asphalt is also in short supply.Coal tar pitch is compared with asphalt, and its aromaticity is high, polarity is big, with sandstone
Material has good compatibility and affinity, and the resistance to deformation on coal tar pitch road surface, wear-resistant, driving security are protruded.Therefore, such as
Coal tar pitch and asphalt are mixed using can not only effectively alleviate the asphalt situation that supply falls short of demand, coal tar pitch can be also solved
Superfluous the problem of, it is most important that the advantage of two kinds of pitch can be integrated, make various aspects of performance improve, it is particularly suitable for use in drip
Blue or green high road pavement construction.
However, unmodified asphalt and coal tar pitch can not meet the pavement performance for requiring increasingly to increase, and coal is dripped
Contain substantial amounts of polycyclic arene compound, particularly 3,4- BaPs in green grass or young crops（Bap) contour carcinogenic substance.
China is at present mainly using materials such as polymer, high polymer material and nano materials to asphalt modification, because of addition
Larger, expensive, cost performance is low for Load materials, limits the development and application of modified pitch.Therefore, one is found
Plant the task that efficient and with low cost asphalt modifier is the current most important thing.
It is the Ergol remaining leftover bits and pieces of rectifying in process of production, its complicated component, one that Ergol, which is got a foothold,
As include 35% or so Ergol, 20%-30% Fluorenone, 1% or so benzoic acid and other impurities.Its outward appearance is darkly
Color, the very big even solid of viscosity at normal temperatures, in case of heating, viscosity reduction.According to incompletely statistics, the whole nation is often produced per year
Raw Ergol is got a foothold nearly 3000 tons.Current Ergol, which is got a foothold, can not find a good processing mode, or even have
Producer stealthily burn or bury, greatly pollution is caused to environment, therefore how to handle Ergol getting a foothold also
Into the task of top priority.
The content of the invention
It is an object of the invention to provide a kind of mixed and modified pitch of Ergol leftover bits and pieces, the road of pitch can either be improved
With performance, and polycyclic aromatic hydrocarbon 3 in pitch, 4- BaPs can be reduced（Bap content), utilization can be handled in environmentally friendly manner again
Ergol is got a foothold, with good economic benefit and social benefit.
To achieve the above object, the technical solution adopted by the present invention is：
A kind of mixed and modified pitch of Ergol leftover bits and pieces, it is characterised in that：The modified pitch by following parts by weight raw material
It is made：40-60 parts of asphalt, 20-40 parts of coal tar pitch, 40-80 parts of Ergol leftover bits and pieces, 15-30 parts of glycol monoethyl ether,
10-15 parts of ethylene glycol, 2-5 parts of polyoxyethylene alkylphenol ether, 1-3 parts of aluminium isopropoxide, 1-3 parts of zinc stannate.
Further, the mixed and modified asphalt production process of described Ergol leftover bits and pieces is comprised the technical steps that：
（1）First by the two kinds of reactors of pitch input with reflux, 60-110 DEG C is heated to, is then added into kettle
Glycol monoethyl ether and ethylene glycol, stir 20-30min, mixing speed 300-500r/min；
（2）Ergol leftover bits and pieces, polyoxyethylene alkylphenol ether, aluminium isopropoxide and stannic acid are sequentially added into reactor again
Zinc, stirs 1-2h, mixing speed 300-500r/min, obtains modified pitch mixture；
（3）Finally by obtained modified pitch mixture at 120-125 DEG C, vacuum distillation recovered solvent obtains modified pitch.
Further, described asphalt is 10# asphalt, and softening point is 70-90 DEG C.
Further, described coal tar pitch is one kind or many in low temperature coal tar pitch, medium temperature coal pitch and coal tar pitch
Combination is planted, the wherein softening point of low temperature coal tar pitch is 45-75 DEG C, the softening point of medium temperature coal pitch is 75-95 DEG C, coal tar pitch
Softening point be 95-110 DEG C.
The present invention has the advantages that compared with prior art：
1. the present invention mixes coal tar pitch and asphalt using can not only effectively alleviate the asphalt situation that supply falls short of demand, also
The problem of coal tar pitch is superfluous can be solved, it is most important that the advantage of two kinds of pitch can be integrated, various aspects of performance is improved,
It is particularly suitable for use in bituminous highway pavement construction.
2. the present invention is got a foothold using Ergol makees modifying agent instead of high price raw material, turn waste into wealth, not only reduce into
This, while being conducive to environmental protection.
3. the present invention is made solvent and can effectively be dissolved the 3,4- benzos in pitch using glycol monoethyl ether and ethylene glycol
Pyrene, the active ingredient in being got a foothold with Ergol reacts, so as to reduce containing for 3, the 4- BaPs in pitch
Amount.Meanwhile, ethylene glycol can also improve the low temperature resistivity energy of modified pitch.
4. the present invention makees crosslinking agent using aluminium isopropoxide, the bonding strength and surface adhesion force of modified pitch are improved；Using
Zinc stannate makees anti-flaming smoke-inhibiting agent, have the advantages that it is nontoxic, safe, easily use.
5. polyoxyethylene alkylphenol ether is used cooperatively with aluminium isopropoxide, zinc stannate, the performance of modified pitch is set to obtain more
Good maintenance.
6. modified pitch of the present invention is according to China《Highway engineering pitch and Asphalt Mixture Experiment code》（JPG
E20-2011）Related code carries out softening point, ductility and penetration test respectively, and result of the test shows the modified drip of the present invention
Blue or green softening point, ductility and needle penetration is satisfied by《Standard specification for construction and acceptance of highway asphalt pavement》（JTG F40-2004）In correlation
Regulation, available for bituminous highway pavement construction.
