Description
Technical field
The present invention relates to asphalt modifier fields, especially with regard to a kind of graphene compound rubber asphalt modifying agent and system
Preparation Method and application.
Background technology
Bituminous paving has the characteristics that driving is comfortable, quiet, repair is convenient, at present 95% or more road pavement of the whole world
Bituminous paving, the important materials composition of bituminous paving from initial residual oil, experienced plain asphalt, heavy traffic paving asphalt to making now
Dosage is more than 50% modified pitch, with the quick increase of rapid development of economy traffic loading, plain asphalt or again friendship drip
Has there are various problems in the bituminous paving that blueness is built, if high-temperature behavior deficiency will appear cracking, track, deformation, in cryogenic property
Deficiency leads to the problems such as pavement cracking, cannot be satisfied real requirement.Rubber asphalt be by waste tire processing and
At rubber powder, then the pitch cementing material that is formed after fully being merged with matrix pitch by a certain percentage.Crumber rubber modified asphalt
High-temperature stability, anti-rut behavior and the anti-fatigue performance of mixture are equal or are slightly better than SBS modified pitch, but more meet environmental protection
It is required that increasingly all circles is caused to pay attention to.However in the practical application of rubber powder modified asphalt, there is also some technologies to ask
Inscribe urgently to be resolved hurrily, the compatibility of rubber and matrix pitch is insufficient, causes the storage stability of modified pitch bad, process
The secondary pollution problems of high temperature and incident serious smell and dust are needed, and then influence the big of rubber asphalt
Sizable application.
Graphene is a kind of new function material, is keyed by stronger σ between the carbon atom in structure, makes graphite
Alkene piece has extremely excellent mechanical property.Currently, the method for preparing two-dimensional graphene can be divided into two kinds:One is top-down sides
Method, exactly from than graphene higher structure graphite or carbon nanotube decompose to obtain graphene, as mechanical stripping method, intercalation shell
From method, solvent liquid phase stripping method and oxidation-reduction method etc.;Another is bottom-to-top method, is exactly utilized than graphene more
The carbon source (small molecules such as methane, CO, alcohol) of low structure prepares graphene by CVD, arc discharge, solvent-thermal method etc..Graphite
The performance in a particular application of alkene has closely bound up with preparation method.
Most of to use graphene oxide at present in terms of graphene pitch, using graphene oxide as additive, SBS makees
For modifying agent, with matrix pitch, sulfur containing promoter is mixed, and obtains graphene modified pitch;Either by matrix pitch and
Modifying agent mixes, and adds carboxy-modified graphene oxide, obtains the PE modified drip based on carboxy-modified graphene oxide
It is green;In addition, also having graphene oxide and ethyl alcohol ultrasonic disperse by a certain percentage, it is configured to graphene oxide colloidal sol, with medium temperature
Coal tar pitch uniformly mixes, to get to final products until the solvent in pitch is evaporated completely.The prior art indicate that:Stone
The addition of black alkene can improve the adhesiveness of pitch, mechanical property, height temperature stability, high temperature Rut resistance etc..
But since graphene oxide has hydrophily, the poor compatibility with pitch, although being functionalized to it, graphite oxide
Alkene still be two-dimensional slice structure, by its in pitch directly it is fully dispersed, technically have certain difficulty;In the prior art
The degree of cross linking of graphene and pitch is improved using the graphene of nitrogen or sulfur doping, but sulphur-containing substance is not environmentally friendly enough, if in construction
There is harmful substance release, health can be endangered.
The technique used in terms of graphene pitch at present approximately as:Graphene is subjected to functionalization, then by graphene, drip
Green and modifying agent mix co-melting, and this co-melting hybrid mode keeps the interface performance of three poor, and compatibility is bad, causes
Degree of scatter of the graphene in pitch be not high, and stability is unable to get guarantee.
Therefore, graphene is made directly to disperse just to need relatively high additive amount in pitch just using co-melting hybrid mode
Energy enhancing effect, in the prior art, graphene additive amount accounts between the 0.1%~5% of pitch gross mass, and some is even as high as
10% or more.This has been considerably improved the cost of graphene modified pitch, is unfavorable for promoting the use of.
