Description
Technical field
The invention belongs to building material field, be specifically related to a kind of color asphalt and preparation method thereof.
Background technology
Colorful Asphalt Pavement has and significantly beautifies road environment effect, better coordinate with the art of architecture around, beautifying city, induction traffic, promote traffic safety, improved greatly the function such as monotonicity on common black road surface, thus the increasing region such as use in the traffic guidance section of the newly-built road in significant city, square, high-grade highway, thus can embody feature and the style in a country or a city.At present China various places Colorful Asphalt Pavement that had build in various degree.
At present, have and understand that very much accurate Lee and document all disclose various chromatic bituminous cements.
But no matter the production ways of color asphalt is that traditional decompression takes off matter or utilizes modern industry petrochemicals to mix the polymkeric substance light color cementing material suitable with asphalt performance, its price is all considerably beyond current plain asphalt or modifying asphalt price.By current market value, the price of plain asphalt is 3000-3500 yuan/ton, SBS polymer modified asphalt price is about 4000-5000 yuan/ton, the price of two color asphalts is more than 10000 yuan/ton, color asphalt price is more than the twice of common modifying asphalt, thereby the cost of whole color asphalt is significantly improved, and has seriously restricted popularization and the development of Colorful Asphalt Pavement, reduce the cost of colored road surface, the one, the cost of reduction starting material (color asphalt); The 2nd, reduce the equipment dropping into of producing, and then reduce cost of investment.
In addition, in road surface utilizes, wherein there is bad dispersibility in color asphalt of the prior art, and pavement cracking is serious, and road surface color fastness is poor, fade serious, easily aging, not water-fast, not acidproof, and the problems such as poor heat stability, effect is not fully up to expectations.Therefore, be necessary very much to work out a kind of new color asphalt.
Summary of the invention
The deficiency that the present invention is directed to the problems referred to above, provides a kind of color asphalt and preparation method thereof, its objective is a kind of low production cost is provided, high-temperature stability, water resistant damageability, weather resistance, all good color asphalts of elasticity dispersiveness.
For realizing object of the present invention, be achieved through the following technical solutions:
A kind of chromatic bitumen mixture, comprises following component: 10～30 parts of base oils, 10～30 parts of thermoplastic elastomers by weight percentage, 0.5～1 part of SBR, 1～2 part of PE, 20～30 parts of petroleum resin, 5～20 parts of pigment, 10～30 parts of breeze or cement, 10～30 parts of stone flours.
As further illustrating, the above petroleum resin is C5 copolymerized petroleum resin or C9 copolymerized petroleum resin.
As further illustrating, the above pigment is ferric oxide.
As further illustrating, the above base oil is that viscous crude subtracts that two fissions heavily moisten or subtract that four hydrogenation heavily moisten, one or more in KP6040.
As further illustrating, the above thermoplastic elastomer is that vinylbenzene-Ding ethene-vinylbenzene lacks section multipolymer.
As further illustrating, the preparation method of the above a kind of chromatic bitumen mixture, comprises the following steps:
(1) according to described weight percent proportioning, add base oil, be heated under 158 ℃～190 ℃ conditions, add thermoplastic elastomer and SBR to stir melting, after dissolving completely, add PE, petroleum resin, finally add pigment, after being uniformly mixed, prepare color asphalt;
(2) color asphalt of step (1) gained is heated to 90 ℃～100 ℃, directly joins mixing in cylinder of asphalt mixing plant, then mix and stir and make product with breeze or cement, stone flour.
Know-why of the present invention is: carry out the color asphalt that obtains after modification, be heated rear the mixing in cylinder of asphalt mixing plant of directly joining, then mix and stir and just can directly prepare chromatic bitumen mixture with breeze or cement, stone flour.
Raw material base oil in the present invention, thermoplastic elastomer, SBR, PE, petroleum resin, pigment, breeze, cement, stone flour all can be bought and obtain on market.
Compared with prior art, the beneficial effect having is in the present invention:
1. production technique of the present invention is simple, and used device is few, and raw materials for production are with low cost, is easy to scale operation and popularization.
2. use thermoplastic elastomer and SBR to carry out modification to pitch, make chromatic bitumen mixture product not yielding, good springiness, simultaneously in high-temperature stability, water resistant damageability, weather resistance, the aspects such as elasticity dispersiveness all can reach dark asphalt mixture performance.
3. produce the pigment that passes through to add different colours in this product process, make color asphalt have distinct colors, in the present invention, pigment adopts the ferric oxide that adds different specific weight to decide the shade of color asphalt to meet different needs.
