Description
Technical field
The present invention relates to technical field of road engineering, more particularly to a kind of color asphalt.
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 color asphalt.
The technical problems to be solved by the invention are achieved by the following technical programs：
A kind of color asphalt is made of the raw material of following parts by weight：35-45 parts of viscous crude, 18-25 parts of Petropols, benzene second
Alkene -3-6 parts of butadiene-styrene block copolymer, 5-10 parts of low density polyethylene (LDPE), 4-10 parts of inorganic pigment.
Further, the inorganic pigment is iron oxide red, chrome oxide green or iron oxide yellow.
Pigment can be divided into organic pigment and inorganic pigment two major classes with regard to its chemical composition.Organic pigment is quick to alkaline reaction
Sense, and weatherability is poor, and stability is poor, fugitive color discoloration, so should avoid using in economical Colorful Asphalt Pavement.It is inorganic
Pigment yield is big, and price is relatively cheap, has excellent weatherability, and stability is strong under the influence of light is with warm, not fugitive color.
Iron oxide red scientific name di-iron trioxide (Fe2O3), abbreviation iron oxide red, it is the oxide of most stable of iron.Due to life
Production. art is different, and the crystal structure and physical behavior of iron oxide red are also different so that the color of iron oxide red is from orange red to aubergine
Differ.Iron oxide red 5.00~5.25g/cm3 of density, 1565 DEG C of fusing point is powdered, nontoxic.Iron oxide red has excellent face
Item matter, covering power and tinting strength, tinting power are very strong.Its high temperature resistance is extremely strong, and heat resistance is up to 1200 DEG C.It to air and
The effect of water is also sufficiently stable, has excellent weatherability.
Iron oxide yellow alias iron carbonyl, abbreviation iron oxide yellow.It is a kind of basic anhydride that chemical property is more stable, molecular formula
For Fe2O3 H2O.Iron oxide yellow density is 2.44~3.60g/cm3, and 350~400 DEG C of fusing point is powdered, nontoxic.Iron oxide yellow
Be usually used in the coating of building decoration, it may also be used for ink, plastics colorant etc..
Chrome oxide green abbreviation chrome green, main component be chrome green (Cr2O3), color usually be in shallow olive-green or
Dark olive green color.Density is 5.40g/cm3, and fusing point is 2435 DEG C, refractive index 2.5.Chrome oxide green can be used for metallurgy, colour, match
The pigment etc. of the fine arts processed.
Further, the preparation method of the Petropols is：（1）With ethylene unit by-product pyrolysis c9 fraction in vacuum degree
, by rectification under vacuum, to intercept boiling point in 100-150 DEG C of C9 components as raw material A under the conditions of -0.085MPa；With ethylene unit
By-product pyrolysis c9 fraction or pyrolysis C 5 are existed under the conditions of vacuum degree is -0.090MPa by rectification under vacuum, interception boiling point
It is raw material B that 160-175 DEG C of fraction, which obtains dicyclopentadiene DCPD enriched compositions,；Above-mentioned raw materials A and B in mass ratio 2-6: 1 is mixed
Conjunction obtains reaction raw materials C；（2）In the reaction kettle with forced circulation, the reaction raw materials C of said ratio is put into advance, is enabled anti-
It answers material to be reacted 25-30 hours under the conditions of 180-240 DEG C, obtains polymer fluid；（3）Above-mentioned polymer fluid is entered in insulation still,
The composite antioxidant for accounting for polymer fluid mass ratio 2~5 ‰ is put into again, and keeps the temperature 10-15 hours under the conditions of 180-200 DEG C；（4）It will
It is -0.07MPa that the polymer fluid that step (3) obtains, which delivers into top vacuum degree, and the desolventizing that 90~120 DEG C of tower top temperature evaporates tower
Interior carry out solvent removal, control reflux ratio are 2；Tower top obtains solvent of the boiling point at 85-200 DEG C, and bottom of tower obtains resin liquid；（5）
Above-mentioned resin liquid is input into the extracting of row steam distillation, top vacuum degree -0.0850MPa extracts several equal molecules by stripping
Oligomer of the amount less than 400 is to get to Petropols.
Further, preparation method includes the following steps：According to parts by weight successively by viscous crude, Petropols input development tank
Then fully reaction again puts into Styrene-Butadiene-Styrene Block Copolymer and inorganic pigment in the development tank, most
Low density polyethylene (LDPE) is put into the development tank afterwards and is fully reacted, the color asphalt is made.
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
