Further, the SBS modifier is SBS, and its addition is dripped for matrix
The 4~5% of blue or green weight content.
Further, the compatilizer is the weight content 1~5% of matrix pitch, and fragrance point content is more than 70%, 100
DEG C kinematic viscosity is not less than 30cst.
Further, the addition of the solubilizer is 2~3 parts of matrix pitch weight content.
Further, the age resister is that petroleum base antioxidant T203 is host, is aided in ultra-violet absorber carbon black
And initiator, the age resister addition is the 0.1-0.2% of the weight of matrix pitch.
Further, the stabilizer is based on sulphur class crosslinking agent and resinae stabilizer, and adds butylbenzene class crosslinking coagent
And inorganic salts, the stabilizer addition is the weight content 0.2~0.3% of matrix pitch.
A kind of MEREY-16 crude oil straight asphalt produces the preparation method of SBS modified pitch, comprises the following steps：
1) matrix pitch is prepared using MEREY-16 crude oil；
2) additive is added, and is reacted under following process conditions：
A, shear temperature are 180 DEG C -190 DEG C；
B, developmental temperature are 180 DEG C~185 DEG C；
C, storage temperature are 155 DEG C~160 DEG C
Compared with prior art, the beneficial effects of the invention are as follows：
A kind of MEREY-16 crude oil straight asphalt production SBS modified pitch of the present invention and preparation method thereof, MEREY-
16 crude oil straight run obtain matrix pitch, in the presence of additive have softening point higher, its softening point bring up to 75 DEG C with
Upper and excellent cryogenic property, 5 DEG C of ductilities are more than 30cm.
Additionally, SBS modified pitch of the invention also has good storage stability, long-distance transportation demand is met.
Specific embodiment
The preferred embodiments of the present invention are illustrated below, it will be appreciated that preferred embodiment described herein is only used
In the description and interpretation present invention, it is not intended to limit the present invention.
A kind of MEREY-16 crude oil straight asphalt production SBS modified pitch of the present invention, its dispensing：SBS modified pitch
Including matrix pitch and additive, in the additive comprising SBS is modified, tapped oil, compatilizer, solubilizer, age resister and
Stabilizer, matrix pitch is by MEREY-16 crude oil through atmospheric and vacuum distillation unit straight run.
Production technology：By MEREY-16 crude oil through distilling apparatus deep drawing, obtain needle penetration and dripped in 45~55 (0.1mm) matrix
It is blue or green.It is subsequently adding additive to be modified, wherein the SBS modifier in additive accounts for the 4% of pitch weight, compatilizer and accounts for pitch
Weight 2%, solubilizer accounts for the 2.5% of pitch weight, stabilizer and accounts for pitch weight 0.2%.The type SBS modifying agent of selection is
SBS.Finally, by matrix pitch and additive in 185~190 DEG C of shear temperature, hair
It is 185~180 DEG C to educate temperature, and storage temperature using high concentration premix at 155 DEG C to be sheared, stabilizer is reacted by mother liquor method
Finished product SBS modified pitch.
The SBS of line style, has the characteristic of rubber and plastics concurrently, can be with water, weak
Acid, alkali etc. are contacted, with excellent tensile strength, big surface friction coefficient, low temperature performance well, excellent electrical properties, processing characteristics
The characteristic such as good.
During the modified asphalt production device had by oneself for company of process units, the present apparatus grinds using four tanks three, setting
Intermediate swellings tank (the 30m of Large Copacity3), semi-automatic continuous production, production technology characteristic is shear at high temperature, lower the temperature into change, low
Temperature storage, have the advantages that it is swelling fully, be evenly distributed, long-time storage, steady quality.In process application Large Copacity
Between swelling can (30m3), premixed using SBS modifier high concentration, swelling shears technique again after first shearing, effectively improve production effect
Rate, improves dispersion of the SBS modifier in pitch.
The additive also includes solubilizer, and addition is the 2.5% of matrix pitch weight content, be it is a kind of with esters,
Alcohols, fatty acid compound are the mixture of main component, are dark brown viscous liquid, 100 DEG C of kinematic viscosity under normal temperature
For 10~30mm2/s, (mean molecule quantity is lower, and viscosity is lower, and lower temperature resistance is better, but heat resistance is poorer, and flash-point is lower；Averagely
Molecular weight is higher, and viscosity is higher, and lower temperature resistance is more poor).Principle be mainly it is following some：1st, containing big in the mixture molecule
There are the function of thermo oxidative aging in amount hydroxyl, ester group, carboxyl, these functional groups in itself；2nd, the mixture can improve the low of pitch
Warm plasticity, thus improve the low-temperature ductility of pitch；3rd, the functional group such as hydroxyl, carboxyl in the mixture can be with pitch in pitch
In matter, colloid there is esterification in carboxyl or hydroxyl, and the carboxylate of generation is also improved the effect of pitch cold plasticity.
The solubilizer added in the present invention is alternative not less than compatilizer addition in proportion, for production auxiliary agent cost
Influence it is minimum.
Age resister is that petroleum base antioxidant T203 is host, is aided in ultra-violet absorber carbon black, initiator, and it adds
Dosage is the 0.15% of the weight of matrix pitch.Age resister can improve modified pitch high-temperature aging resisting ability, slow down modified
Asphalt performance is decayed, and is increased the service life.
Stabilizer adds butylbenzene class crosslinking coagent and nothing based on sulphur class crosslinking agent and special modified resinae stabilizer
Machine salt.The cross-linking reaction of SBS can be triggered, promote scattered SBS to form the spacial framework of stabilization, prevent SBS and pitch
Separate.Meanwhile, stabilizer triggers SBS that graft reaction occurs with pitch.Addition is the weight content 0.25% of matrix pitch.
Stabilizer mother liquor method addition in the present invention, powdery stabilizer is well mixed with matrix pitch in advance, with liquid
Form enters into finished product development tank, and the supplementary means for being stirred increases response intensity, it is ensured that finished product is developing finger in 6 hours
Qualified, stable system is marked, long-distance transportation demand is met.
Finally it should be noted that：The preferred embodiments of the present invention are these are only, is not intended to limit the invention, although
The present invention is described in detail with reference to embodiment, for a person skilled in the art, it still can be to foregoing
Technical scheme described in each embodiment is modified, or equivalent is carried out to which part technical characteristic, but it is all
Within the spirit and principles in the present invention, any modification, equivalent substitution and improvements made etc. should be included in protection of the invention
Within the scope of.
