Description
Technical field
The present invention relates to building material technical field, especially a kind of high viscosity composite modified asphalt and preparation method thereof.
Background technique
It is well known that some areas of China's northeastern Inner Mongolia belong to seasonal iced areas, day and night temperature it is larger and
Ultraviolet radiation is serious, and the bituminous pavement in these areas, which exists, to be easy to appear cold cracking and caused because endurance quality is weak
A series of Asphalt Pavement Damages, or even the problem of traffic safety can be seriously affected.In this regard, being proposed in industry to existing pitch
Many improvement projects.
Such as using SBR modified pitch as the scheme of representative, because its cryogenic property is excellent, and there is certain uvioresistant
Aging action and in severe cold, intensive ultraviolet area using more.However, as Chinese invention patent application 201810164122.2 is public
A kind of composite modified asphalt and preparation method thereof suitable for High aititude extremely frigid zones opened, composite modified asphalt component include
SBS modifier 1-3%;Nano-ZnO 1-3%;Sulphur 1-2%;Stabilizer 0.15-0.3%, surplus are SBR modified pitch;Its
By SBS modifier and nano-ZnO being added in SBR modified pitch to improve performance.For another example Chinese invention patent application
A kind of nanoparticle SBR composite modified asphalt disclosed in 201410452130.9, nanoparticle SBR composite modified asphalt is by nanometer
SiO2 particle, butadiene-styrene rubber and matrix pitch composition.According to the record of its specification, with preferable cryogenic property, performance
For its 5 DEG C of ductility about 30.But its high-temperature behavior not on the books.It can be seen from this that the height of these SBR composite modified asphalts
Warm nature can be poor, is not able to satisfy the biggish seasonal freezing region road of day and night temperature and demand is used for a long time.
For another example using rubber modified asphalt as the scheme of representative, resin, the hydrocarbon in pitch are absorbed using waste rubber powder
A variety of organic matters such as class mention wet rubber powder, expansion, viscosity increase, softening point by a series of physical and chemical changes
Height, and the viscosity, toughness, elasticity of rubber and pitch have been taken into account, to improve the pavement performance of rubber asphalt.However, as in
A kind of rubber powder modified asphalt disclosed in state's application for a patent for invention 201810310742.2 and preparation method thereof, raw material are as follows: 30-40

1-2 parts of PE modifying agent, 1-10 parts of solubilizer, 1-3 parts of aromatic naphtha, 15 DEG C of ductilities are greater than 160, but are not documented in
Product ductility under lower temperature, does not record its high-temperature behavior yet.For another example Chinese invention patent application 201711415343.4
Disclosed a kind of high-viscosity asphalt, consisting of: Styrene-Butadiene-Styrene Block Copolymer (SBS) 3-8%, butadiene-styrene rubber
(SBR) 1-3%, compatilizer 2-10%, stabilizer 0.08-0.3%, dodecyl sodium sulfate 0.5-2%, polyphosphoric acids (PPA)
0.8-1.5%, other is matrix pitch.However, its 5 DEG C of ductilities only about 30, can not adapt to low temp area.It can be seen from this that
Rubber modified asphalt brings a negative impact cryogenic property, increases through the modified asphalt viscosity of polyphosphoric acids, high-temperature behavior have compared with
It is apparent to improve, while temperature sensitivity reduces, but polyphosphoric acids cannot improve the cryogenic property of pitch.
In conclusion existing modified pitch largely only merely improves the high-temperature behavior or low temperature properties of pitch
Energy;Therefore, existing modified pitch for summer temp is higher and seasonal freezing region adaptability that winter temperature is low is poor.
