Description
Technical field
The invention belongs to chemical technology field, a kind of modifying agent mother liquor and road asphalt and preparation method thereof are related generally to,
Especially a kind of preparation method by the road asphalt that coal tar pitch and asphalt are raw material production.
Background technique
With the continuous expansion of highway construction scale, also synchronous high-speed increases the road asphalt market demand.Currently, petroleum provides
Source is increasingly deficient, and the processing added value of coal tar asphalt (coal tar pitch) is low, the market price is only half of asphalt or so,
For this purpose, researcher constantly probe into whether can using coal tar pitch as production road asphalt raw material.The coal of produced in conventional processes
The disadvantages of that there is such as thermal sensitivity is poor, easy to aging for pitch, poor ductility, is unable to satisfy the needs of road project.For
The shortcomings that in terms of coal tar pitch service performance, coal tar pitch is mixed with asphalt, is able to ascend road asphalt material property, is one
One of feasible practical technique of kind.
Using SBS as modified oil pitch prepared by macromolecule modifier, due to the modifying function of SBS, petroleum road is improved
The high temperature performance and response to temperature of road pitch, so that the bearing capacity of Modified Bitumen Pavement, fatigue resistance are improved.
CN101985526A discloses a kind of composite modified asphalt for high-grade high road and preparation method thereof, using 69% ~
90% asphalt, 5% ~ 30% coal tar pitch, 1% ~ 10% Styrene-Butadiene-Styrene Block Copolymer etc. prepare compound
The method of modified pitch, preparation process are by asphalt, coal tar pitch and Styrene-Butadiene-Styrene Block Copolymer
Target product is prepared into Deng common heating and through colloid mill grinding, stirring development.It will using conventional Production Process of Modified Bitumen
Whole materials all grind shearing, and milling time is long, power consumption is big, since the asphalt content of coal tar pitch is excessively high, in asphalt adhesive
Glue nuclear volume is excessive in body structure, influences the colloform texture composition of pitch, will lead to pitch poor in flexibility, elasticity and low temperature properties
It can be deteriorated, steady heat storage performance is also bad.
CN103694716A discloses a kind of coal tar pitch and preparation method thereof of modification, using 10 ~ 20 parts of asphalt,
50 ~ 30 parts of coal tar pitch, 1 ~ 4 part of SBS, 5 ~ 35 waste Crumb rubber, 0.5 ~ 1 part fire retardant etc. prepare the side of modified pitch
Method.In the method, coal tar pitch is accounted for relatively high (50 ~ 30 parts of coal tar pitch), less (10 ~ 20 parts of the petroleum drip of asphalt accounting
It is green), simultaneously because the asphalt content of coal tar pitch is excessively high (typically larger than 20%), the asphalitine in pitch colloform texture is caused to contain
Measure excessively high, the composition matching of pitch colloid is unreasonable, will lead to pitch poor in flexibility, and cryogenic property and hot storage stability become
Difference.In addition, added in pitch 5 ~ 35 parts of waste Crumb rubber will lead to pitch mix temperature it is excessively high and hot storage stability becomes
Difference.Its preparation process is to be pre-mixed asphalt, coal tar pitch and cosolvent and SBS, then grind through colloid mill, simultaneous grinding
Process is needed the overground grinding of the larger component of the accountings such as asphalt, coal tar pitch and cosolvent and SBS, grinds that the scale of construction is big, power
Consumption is big.
Above two technology is not all illustrated the detoxification performance of pitch.
CN102585527A discloses a kind of coal tar pitch and preparation method thereof of modification, by 70 ~ 80% asphalt, 10 ~
20% coal tar pitch and 10 ~ 20% diatomite carry out heat and melt mixing, and mix asphalt adhesion obtained is good, and the pitch of preparation mixes
Expect that dynamic stability improves 3 ~ 4 times, rutting resistance improves.Meanwhile no using naphthalene, phenol contained by kieselguhr adsorption coal tar pitch etc.
It is saturated aromatic hydrocarbon, reduces the toxicity of coal tar pitch.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of modifying agent mother liquor and road asphalt and preparation method thereof,
The road asphalt and preparation method thereof especially produced with coal tar pitch and petroleum pitch feedstock.It is dripped with the modifying agent mother liquor and petroleum
The matching of green and coal tar pitch keeps the colloform texture of road asphalt product more reasonable, the high and low temperature of pitch to prepare road asphalt
It can all be strengthened, while can also reduce the toxicity of pitch.
