The invention provides a high-softening-point SBS (styrene-butadiene-styrene) modified asphalt and a preparation method thereof, belonging to the technical field of construction materials. The modified asphalt is prepared from substrate asphalt as the raw material, and the substrate asphalt is compounded from oil sand and CNOOC crude oil. The preparation method comprises the following steps: heating the substrate asphalt to a certain temperature until the substrate asphalt can completely flow; adding a linear SBS modifier into the substrate asphalt to carry out swelling and shearing; and adding a stabilizer into the mixture of the substrate asphalt and SBS modifier, and stirring. The oil sand is used as the raw material, thereby fully utilizing the oil sand resource and obviously enhancing the softening point of the asphalt (the softening point can be higher than 85 DEG C); by adopting the CNOOC crude oil and linear SBS modifier, the prepared product has high stability, and the low-temperature, 135 DEG C viscosity and other indexes satisfy the national modified asphalt standard for roads; and the technique is simple and easy to implement, convenient to operate and convenient for industrial production.
Description
Technical field
The present invention relates to a kind of pitch for highway and preparation method thereof, belong to building material technical field, be specifically related to a kind of high softening-point SBS modifying asphalt prepared with oil-sand and CNOOC's Oil Blending gained matrix pitch.
Background technology
Adopting polymkeric substance to carry out modification to road bitumen is the important measures improving and improve Asphalt Mixture Performance, use properties is improved by polymkeric substance is mixed in road bitumen, energy significant prolongation pavement life, reduce noise, improve road-ability and security, SBS is a kind of thermoplastic elastomeric block copolymer, and SBS modifying asphalt, owing to having good low temperature flexibility and high temperature flexibility, lower temperature sensitivity, becomes the main product in modifying asphalt.
Linear SBS conventional at present and star-shaped sbs.When adopting linear SBS to prepare modifying asphalt, when reaching comparatively more than high softening-point (as 70 DEG C), generally can need higher volume, the requirement of low-temperature ductility could be met simultaneously, but viscosity are excessive and storage stability is bad to cause 135 DEG C.When reducing SBS volume, softening temperature can reduce, and low-temperature ductility does not reach requirement yet.Reduce properties-correcting agent consumption, increase sulfur consumption, although can obtain comparatively high softening-point, low-temperature ductility just can not be up to standard, and 135 DEG C of viscosity also can be excessive; When adopting star-shaped sbs to prepare modifying asphalt, because star-shaped sbs more linear SBS structure is finer and close, molecular weight is larger, necessarily increases the difficulty mixed with matrix pitch, and storage stability is difficult to ensure, adds the difficulty of production.CN200510134354.6 adopts mother liquor legal system for modifying asphalt, and shortcoming is the preparation overlong time of rubber cement mother liquor, needs 4.5 ~ 12 hours, and mother liquor method must through 2 mixing, and technique is loaded down with trivial details, is unfavorable for the simplification of producing.
Oil-sand is a kind of sand shape mineral reserve containing crude oil, composition comprises sand, pitch, mineral substance, Tu Heshui, contained viscosity of crude is higher, asphalt content is more, the rich reserves of oil-sand, as an alternative resource, especially a kind of safe alternate resources is most valuable to the whole world, mix refining gained pitch with oil-sand and other oil sources and prepare modifying asphalt, both took full advantage of oil-sand resource, and contributed to again the high-temperature behavior improving modifying asphalt.
Summary of the invention
In order to solve problems of the prior art, the present invention proposes a kind of high softening-point SBS modifying asphalt and preparation method thereof, it take matrix pitch as raw material, matrix pitch is oil-sand and CNOOC's Oil Blending gained, add linear SBS modifier, stablizer, its softening temperature of SBS modifying asphalt prepared reaches more than 85 DEG C, and the indices of SBS modifying asphalt all reaches requirement.
