Description
Technical field
The present invention relates to a kind of chromatic bituminous cement and preparation method thereof.
Background technology
Adopt the color asphalt concrete road surface pavement in road, one has beautifying city, road improvement environment, shows the Urban style effect, specifically is applied to the ground such as avenue, square, landscaped area, park and tourist sight road; Its two Colorful Asphalt Pavement has the wagon flow of inducing, and makes the effect of traffic administration visualize, specifically is applied to distinguish highway section and the track of difference in functionality, to improve officer's recognition effect, increases the traffic capacity and the traffic safety of road; Its three novel Colorful Asphalt Pavement, higher than plain asphalt surface friction coefficient, so also have anti-skidding effect.When the driver runs into the emergency situation brake, colored road surface can prevent defective steering stabilizer.Under different temperature and outside atmosphere effect, its high-temperature stability, anti-water damage and weather resistance are all very good, and do not occur that distortion, asphalt membrane such as peel off at the phenomenon, good with basic unit cohesiveness.
Colorful Asphalt Pavement mainly refers to the bituminous concrete pavement that adds pigment, the bituminous pavement that uses petroleum resin (albino bitumen) and add pigment in compound, what color asphalt was used is light color (or colourless) agglutinate, to use at present more kind, it is to adopt modern petrochemicals, as perfume oil, polymkeric substance, resin etc. mix the binder suitable with the plain asphalt performance, then add certain pigment, make it to present certain color.
Chinese patent ZL03802619.X discloses a kind of colourable binder compositions for the synthesis of pitch, and described composition contains resin, lubricating oil and/or lubricating oil extract and amides additive; Chinese patent ZL93107531 discloses a kind of Binder for Colored Pavement, and its composition mainly comprises petroleum resin, SBS and lube oil finishing extraction oil.The principal feature of above these patents is to be to adopt resin, lubricating oil and/or lube oil finishing to extract the synthetic asphalts that oily and a small amount of mixed with polymers forms colourable binder compositions out.
The synthetic albino bitumen of petroleum resin and extract oil of lubricating oil does not have the macromolecular substance such as traditional asphalt studies on asphaltene, so the more common dark asphalt of the performance of color asphalt still has gap, especially high-temperature behavior.Can partly improve the performance of chromatic bitumen mixture by adding wherein a large amount of high molecular polymers as SBS, PE, EVA, SBR, but effect is still undesirable.If polymkeric substance surpasses 10% at the addition of color asphalt, although can make the chromatic bitumen mixture high-temperature behavior meet the demands, but can produce the excessive problem of viscosity, cause color asphalt to go wrong in the links such as paving, roll of production, storage, transportation, pumping and compound; On the other hand, the cost of the color asphalt of high polymers content is very high.Due to the high-temperature behavior deficiency of color asphalt, cause it can not be applied in the occasions such as the large or porous pavement of southern high-temperature, the volume of traffic.
