Description
Technical field
The invention belongs to asphalt warm mix technical fields, and in particular to a kind of environmental protection warm-mixed asphalt and preparation method thereof.
Background technology
Asphalt concrete pavement is with its advantages that comfortable, wearability is good, noise is relatively low, maintenance is simple of driving a vehicle, gradually
Instead of cement concrete pavement, and as China and one of the principal mode of developed country's highway pavement.
There are generate a large amount of pitch in mix temperature and mat formation temperature height, work progress for traditional hot-mix asphalt mixture
The defects of flue gas, high harmful gas emission, causes many Ecological and environmental problems.
Wherein, bitumen flue gas is mainly volatile organic compounds, and benezene material therein is strong carcinogen, with society
It can develop and people are to environmental protection, safe attention, the smoke problem of pitch is urgently to be resolved hurrily, the emulsification drip used in the prior art
The technologies such as blueness, liquid asphalt all cannot fundamentally solve the smoke problem of pitch, and also reduce the performance of bituminous paving.
Invention content
A kind of environmentally friendly warm-mixed asphalt of present invention offer and preparation method thereof, the additive in the environmental protection warm-mixed asphalt can have
Effect reduces asphalt viscosity, and to reduce the mixing and stirring of mixture, pave, roll temperature, overcoming it to pollute, environment, energy consumption are big etc. to ask
Topic.
The technical solution adopted by the present invention is as follows：
A kind of environmental protection warm-mixed asphalt, including following components in terms of mass fraction：100 parts of matrix pitch, 0.5~2 part
Wax, 0.5~2 part of conditioning agent, 0.5~10 part of smoke suppressant, 1~3 part of stearic acid.
The matrix pitch is heavy traffic paving asphalt.
The wax is that one or more of paraffin, polyethylene wax, oxidized polyethylene wax substance combine, preferably paraffin,
The paraffin is the wax (slack wax and refined microwax etc.) for obtaining and refining from oil, fusing point 85~90 DEG C, it is close
Degree is 0.87~0.92g/cm3。
The conditioning agent is the substance combination of one or both of catalytic cracked oil pulp rich in aromatic hydrocarbons, aromatic naphtha.
The smoke suppressant is at least two substances combination in polyethylene, coumarone indene resin, expansible graphite, is preferably set
The mass ratio of lipid polyethylene and/or coumarone indene resin and expansible graphite is 1：1~4：1, the polyethylene is low-density
Polyethylene, 0.910~0.940g/cm of density3, the expansible graphite coefficient of expansion >=200.
The preparation method of the environmental protection warm mix suppression cigarette, includes the following steps：Matrix pitch is heated to molten condition, is added
Paraffin, conditioning agent, smoke suppressant and stearic acid stir evenly.
Preferably, matrix pitch is heated to 110~120 DEG C.
Preferably, it is stirred in 150~170 DEG C of constant temperature, mixing time is 10~20 minutes.
Compared with prior art, the present invention has following excellent technique effect：
Conditioning agent in the environmental protection warm-mixed asphalt, to increase the compatibility of each component, keeps smoke suppressant more preferable with wax
Ground is compatible with pitch, inhibits the flue gas volatilization in pitch, and can improve the high-temperature behavior of pitch.Expansible graphite is 200
DEG C or more high temperature when start to expand, graphite after expansion forms a good heat insulation layer, can be effectively heat-insulated oxygen barrier, to play
Press down the effect of cigarette.And wax can effectively reduce the viscosity of pitch with stearic acid interaction, enable pitch at a lower temperature
Construction, to reduce the volatilization of bitumen flue gas.
Specific implementation mode
The present invention is further explained with reference to embodiments：
Blank example
No. 70 heavy traffic paving asphalts of triumph are heated to melting, the analysis of falling sample.
Embodiment 1
100 parts No. 70 heavy traffic paving asphalts of triumph are heated to 110 DEG C, 2 parts of paraffin, 3 parts of stearic acid, 1.5 parts of poly- second are added
Alkene, 1.5 parts of expansible graphite, 1.5 parts of aromatic naphtha stir 10 minutes in 165 DEG C of constant temperature.
Embodiment 2
100 parts No. 70 heavy traffic paving asphalts of triumph are heated to 110 DEG C, 1.5 parts of paraffin are added, 2 parts of stearic acid, 0.5 part poly-
Ethylene, 0.5 part of expansible graphite, 1 part of aromatic naphtha stir 15 minutes in 160 DEG C of constant temperature.
Embodiment 3
100 parts No. 70 heavy traffic paving asphalts of triumph are heated to 115 DEG C, 0.5 part of paraffin, 1 part of stearic acid, 3 parts of poly- second are added
Alkene, 1 part of coumarone indene resin, 2 parts of expansible graphite, 0.5 part of aromatic naphtha stir 20 minutes in 170 DEG C of constant temperature.
Embodiment 4
100 parts No. 70 heavy traffic paving asphalts of triumph are heated to 120 DEG C, are added 1 part of paraffin, 3 parts of stearic acid, 4 parts of polyethylene,
1 part of expansible graphite, 2 parts of aromatic naphtha stir 20 minutes in 165 DEG C of constant temperature.
Additive in the present invention can effectively reduce the viscosity of pitch, to reduce the mixing and stirring of asphalt, pave,
The problems such as rolling temperature, it overcome to pollute big environment, energy consumption, ageing of asphalt decline.
1 embodiment test result of table
As can be seen from Table 1, pitch of the present invention has lower viscosity at 135 DEG C, can effectively reduce pitch and apply
Work temperature, and 80 DEG C of viscosity increased, and illustrate that pitch is still mixed and stirred, spread out with good under the conditions of reducing construction temperature
Paving, compaction capacity can significantly reduce thermal energy consumption, the discharge for reducing pernicious gas and dust, avoid pitch during mixing and stirring
Heat ageing and performance degradation occurs.Asphalt softening point is higher simultaneously, illustrates that the high-temperature stability of pitch is obviously improved.
