Description
Technical field
The present invention relates to oil product manufacture fields, and in particular to No. 30 hard road bitumens of one kind and preparation method thereof.
Background technique
In recent years, the construction of highway in China has all obtained swift and violent development, but with the road Traffic Volume day of heavy-duty vehicle
Benefit increases, and thus causes pavement track, pit-hole etc. and has become one of Major Diseases performance of bituminous pavement.Largely studies and answer
With practice have shown that, possess high softening-point, the hard grades of bitumen of low needle penetration feature can effectively alleviate the diseases such as pavement track.
The hard road bitumen used domestic at present is based on No. 50 pitches, and the production of No. 30 pitch and research are opposite
It is less.
Chinese invention patent CN101492570A discloses a kind of hard road bitumen compositions and preparation method thereof.The group
Conjunction object includes that needle penetration is 351/10mm pitch below, softening agent, chemical modifier and matrix pitch.This patent system is standby
Although hard grades of bitumen high-temperature behavior is good, the cryogenic property analysis of 25 DEG C of ductilities is only done, the drip in national standard has been lacked
Green anti-aging property index test, therefore it is actually unable in the requirement for meeting Ministry of Communications and national standard for hard grades of bitumen.
Chinese invention patent CN104650602A discloses a kind of advanced road hard grades of bitumen and preparation method thereof, this is specially
The raw material of benefit includes de-oiled asphalt, plug slurry oil, polymer modifiers, auxiliary agent.Although the standby hard grades of bitumen performance of this patent system
Well be able to satisfy the index request of No. 30 hard road bitumens, but joined polymer modifiers in its component, thus cost compared with
Height, and preparation process is complicated.
Chinese invention patent CN105694492A discloses a kind of hard grades of bitumen, and raw material includes Persian bank crude oil and Ma Rui-
16 crude oil, extraction oil, rubber oil, second line of distillation is oily, subtract third fractional oil, subtracting four, line is oily.Its production method directly pulls out technique using decompression.This
The raw material sources of patent are relatively narrow, and the production technology of this patent steadily requires strictly the control of vacuum distillation process, therefore limit
Property processed is higher, is unfavorable for promoting.
Summary of the invention
The first purpose of the invention is to provide a kind of No. 30 hard road bitumens, pitch indices made of the present invention
Meet the requirement of No. 30 hard road bitumens of " Ministry of Communications's standard specification for construction and acceptance of highway asphalt pavement " (JTG-F402004).
A second object of the present invention is to provide the preparation methods of above-mentioned No. 30 hard road bitumens.
First purpose of the invention can be realized by technical solution below:
A kind of No. 30 hard road bitumens, being calculated with mass parts includes following components:
75-85 parts of decompression residuum
10-20 parts of de-oiled asphalt mixture
1-5 parts of furfural extract oil mixture
The decompression residuum is the decompression residuum of intermediate base and/or naphthenic base, needle penetration 10-30/0.1mm；
The de-oiled asphalt mixture is de-oiled asphalt and is mixed with heavy deasphalted oil with mass ratio 1:0.4-2.5, is mixed
Needle penetration is 70-90/0.1mm after conjunction；
The furfural extract oil mixture be lightweight deasphalted oil and the line distillate that subtracts four respectively after furfural treatment obtained by
Extraction oil, 1:2-4 in mass ratio mixing gained, arene content >=80% after mixing.
Preferably, the de-oiled asphalt and heavy deasphalted oil are the petroleum crude oil product of intermediate base and/or naphthenic base；
Lightweight deasphalted oil and the line distillate that subtracts four are the petroleum crude oil product of intermediate base and/or naphthenic base；The lightweight depitching
Oil is decompression residuum after solvent deasphalting, deasphalted oil of the carbon residue less than 3.5%；The heavy deasphalted oil is decompression slag
For oil after solvent deasphalting, carbon residue is more than or equal to 3.5% deasphalted oil.Solvent used is propane.
Petroleum crude oil can be divided into paraffinic base crude oil, naphthene base crude and intermediate base crude three classes by group constituent class, wherein stone
Paraffinic crude oil is since paraffin hydrocarbon content is higher, and according to paraffinic base crude oil, as raw material, its end properties is poor, cannot reach
The requirement of No. 30 hard road bitumens.
Decompression residuum refers to the petroleum crude oil residue oil that tower bottom is extracted out after oil plant vacuum distillation tower, is boiled in crude oil
The part that point highest, relative molecular mass are maximum, content of heteroatoms is most and structure is the most complicated.
Product of the decompression residuum after solvent deasphalting is de-oiled asphalt and deasphalted oil, and wherein deasphalted oil is according to residual
Carbon content is divided into lightweight deasphalted oil and heavy deasphalted oil.
Furfural treatment is to use furfural as solvent, the process that ideal composition in raw material is separated with undesirable components.Effect
For the viscosity temperature characteristic for improving oil product, carbon residue and acid value are reduced, improve the anti-oxidative stability of oil product and reduces the color of oil product.
Obtained extraction oil is by-product, arene content with higher.
The preparation method of above-mentioned No. 30 hard road bitumens, comprising the following steps:
1) de-oiled asphalt is concocted at 210-260 DEG C with heavy deasphalted oil, mix homogenously is to being no longer layered as
Only, de-oiled asphalt mixture is obtained；
2) resulting frivolous extraction oil will be processed through furfural treatment technique, and line extraction oil is concocted at 90-100 DEG C with subtracting four
Uniformly until being no longer layered, furfural extract oil mixture is obtained；
3) by decompression residuum and de-oiled asphalt mixture until 130-165 DEG C of mix homogenously to no longer layering, then again
Be added furfural extract oil mixture concocted at 130-165 DEG C or more it is even to being no longer layered；
4) the resulting mixture of step 3) is detected, parameter meets " Ministry of Communications's asphalt highway construction technology
Specification " No. 30 hard road bitumens are product.
Petroleum crude oil just directly passes through after fractionating column obtains various products for producing various raw materials described in this patent
Crossing the oil plants such as furfural treatment, solvent deasphalting, original equipment carries out preceding processing, then de-oiled asphalt and the de- drip of heavy
Green oil is on-line blending to be carried out in pipeline, and frivolous extraction oil and the line that subtracts four extraction oil are then concocted in storage tank, furfural
Decompression residuum with de-oiled asphalt mixture, furfural extract oil mixture is concocted in storage tank.Production method of the invention
Equipment used is the existing equipment of oil plant, is not necessarily to additional customized equipment.
Above-mentioned blending required temperature is provided to keep the mobility of each component, after guaranteeing non-condensing when blending and blending
Uniformity.And due to temperature of each raw material after destilling tower submitting usually all can the required blending required temperature of the present invention it
On, therefore the heating equipment additional without addition.
Compared with prior art, the invention has the following advantages:
1) primary raw material of this patent is the by-product of oil refining, and does not need to additionally incorporate modifying agent, and material quantity is easy to get greatly,
The production cost for reducing hard road bitumen improves the utility value of by-product.
2) this patent takes the production method of blending, reduce crude oil vacuum distillation process to control steadily require it is severe
Scale produces more flexible, easy.
3) hard road bitumen high-temperature behavior made of the present invention can meet the requirement in hot area, and cryogenic property can meet the winter
The requirement of cold-zone and winter-warm syndrome area.
