Description
Technical field
The present invention relates to technical field of road engineering, more particularly to a kind of preparation method of color asphalt binder.
Background technology
Elasticity of the Colorful Asphalt Pavement with asphalt concrete is strong, damping strong and is easy to clean the formedness such as flushing
Can be outer, the monotonicity of plain asphalt road surface black is further improved, can be collocated with each other, coordinate with the building of surrounding, landscape, have
Apparent Landscape benefit.In addition, color asphalt increasingly obtains the organization and management effect of traffic the attention of people.Different colours
Bituminous paving, the recognition effect of driver can be improved, and the attention of driver can also be made more to concentrate, to play
Induce wagon flow, safe driving, the effect for making traffic administration intuitively change.It, can be with such as in the multiple location of Urban Road Traffic Accidents
Driver is intuitively reminded note that driving a vehicle with caution, to a certain extent than vertical traffic sign in making red or yellow road surface
And stroke markings are more preferable on track.
But the performance of existing color asphalt is still to be improved.
Invention content
In order to make up the defect of prior art, the present invention provides a kind of preparation method of color asphalt binder.
The technical problems to be solved by the invention are achieved by the following technical programs：
A kind of preparation method of color asphalt binder, is made of the raw material of following parts by weight：30-38 parts of Petropols,
15-20 parts of aromatic naphtha, 5-10 parts of rubber oil, 5-10 parts of SBR modifying agent, 10-20 parts of inorganic pigment, nanoscale fineness calcium carbonate
0.2-0.8 parts, 0.5-1.2 parts of antioxidant.
Further, inorganic pigment be iron oxide red pigment, chrome green pigment, iron green pigment, titanium dioxide pigment, in chrome yellow extremely
Few one kind.
Further, the antioxidant be 2-hydroxy-4-n-octoxybenzophenone, it is 2,4,6- tri-butyl-phenols, right
It is one or more in tert-butyl phenol.
Further, the preparation method of the Petropols is：（1）By pentadiene, isoprene, 4- vinyl cyclohexyls
Alkene and monoene the hydrocarbon component in mass ratio 1: 0.2: 0.3: 1 obtain dispensing A after evenly mixing；（2）In the reaction kettle with blender
Interior, input accounts for the solvent for reacting total 40~60wt% of quality of material in advance, adds total quality of material 1.2-2wt%'s
Then Friedel-Crafts catalyst is at the uniform velocity added dispensing A, enables reaction mass react 1-3h at a temperature of 25-60 DEG C, obtain
To polymer resin liquid；（3）Above-mentioned polymer resin liquid first carries out alkali cleaning Removal of catalyst with the NaOH solution of concentration 5wt%, then uses
Clear water is washed repeatedly to neutrality, obtains light yellow, clear Petropols liquid；（4）Temperature of the Petropols liquid at 210-250 DEG C
Lower carry out steam distillation obtains Petropols to remove solvent and oligomer.
Further, preparation method includes the following steps：（1）Aromatic naphtha is added according to the parts by weight, is heated to
Under the conditions of 165-190 DEG C, the stirring melting of SBR modifying agent is added, it is thin that Petropols, rubber oil and nanoscale are added after being completely dissolved
Calcium carbonate is spent, inorganic pigment and antioxidant is eventually adding, is uniformly mixed.
The present invention has the advantages that：
The present invention can produce the color asphalt of various colors, improve vision, can be widely used in street, pavement and
The different places such as landscape road can not only meet the needs of various places, while can also beautify the environment.
The present invention realizes the color asphalt production for being prepared have excellent performance at lower cost by being formulated global design
