Description
Technical field
The invention belongs to field of road, and in particular to a kind of asphalt modifier, asphalt and preparation method thereof.
Background technology
With developing rapidly for road traffic, the continuous exacerbation of vehicle load, increasing road surface uses modified pitch.
The use of modified pitch can undoubtedly extend the service life of road, have SBS, poly- in the modifying agent commonly used in road construction at present
After adding pitch with pitch physical and chemical reaction can occur for ethene and butadiene-styrene rubber etc., these polymer so that pitch
Performance is improved, and the pavement performance of asphalt also makes moderate progress, so as to extend the service life of bituminous paving.Many realities
Surface is trampled and studies, by adding the modified pitch of high molecular polymer, its asphalt temperature sensitiveness and brittle temperature obtain
Reduce, softening point is improved, and cracking resistance anti-wear performance is strengthened.Especially SBS modified pitch, its excellent road property
The great attention of highway layout person's door can be received in reagent application process, in China and world wide, modified pitch makes
Increased year by year with ratio, to currently about 60%.
Because complexity and pitch and the polymer of pitch are in composition, structure, the bigger difference of properties, cause to drip
It is blue or green poor with the compatibility of High polymer asphalt modifier, it is not easy to form stabilising system, directly affects the performance of modified pitch.Find
A kind of good asphalt of compatibility is current urgent problem to be solved.
The content of the invention
The present invention provides a kind of asphalt modifier, asphalt and preparation method thereof, to solve asphalt modifier and
Between pitch the problem of poor compatibility.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：
A kind of preparation method of asphalt modifier, comprises the following steps：
S1. count in parts by weight, take 10 parts of SBS polymers, 0.05~0.08 part of vinyltrimethoxy silane, 1~1.7
Part maleic anhydride and 0.5~0.8 part of methyl methacrylate are added in 15 parts of hexamethylenes, are then heated to 60~70 DEG C of dissolvings,
Add in the water that 50 parts of temperature are 68 DEG C with 2000r/min rotating speed stirring and emulsifying, turned after emulsification with 300~500r/min
Fast lasting stirring, add 0.01~0.012 part of dibenzoyl peroxide and react 1~1.5h, reaction cools after terminating, then mistake
Filter, filtration product are dried after acetone washs, and obtain modified SBS powder；
S2. count in parts by weight, by 10 parts of modified SBS powder, 1~2 part of polyphosphoric acids, 0.5~0.8 part of compatilizer and 2
~4 parts of epoxy powder mixing, obtain asphalt modifier.
Further, the content of type SBS is not less than 70% in the SBS polymer.
Further, the compatilizer is any one or a few in rubber oil, castor oil or ditridecyl phthalate.
A kind of asphalt, including asphalt modifier, are counted in parts by weight, the raw material composition of the asphalt
For：100 parts of matrix pitches, 6~10 parts of asphalt modifiers, 5~10 parts of fillers and 0.05~0.12 part of stabilizer.
Further, the gross mass of both compositions of fragrance point and resin accounts for matrix pitch quality in the matrix pitch
80~90%.
Further, the filler is the one or more in zinc oxide, calcium carbonate or portland cement.
A kind of preparation method of asphalt, matrix pitch is heated to 180~185 DEG C, then in a manner of sprinkling
Add asphalt modifier and stabilizer, 20~30min is stirred with 1000~1500r/min rotating speed, add filler, continue to stir
30~45min is mixed, finally obtains asphalt.
Beneficial effects of the present invention：
(1) pitch includes oil, resin and asphalitine this three big component, wherein oil and resin can mutual phased soln, tree
Fat can infiltrate asphalitine, the structure of asphalt be using asphalitine as core, ambient absorption part resin oil dissolve each other thing and
Form micelle.Because the polarity of SBS polymer is small, the poor compatibility between oil and resin so that SBS and pitch it is compatible
Property is poor.It is of the invention first with maleic anhydride and methyl methacrylate-grafted modified SBS polymer, introduce polar group, strengthen SBS
The polarity of polymer, while using vinyltrimethoxy silane as crosslinking agent, to SBS polymer, maleic anhydride and metering system
Sour methyl esters is crosslinked, and one side crosslinking agent can be improved between maleic anhydride and methyl methacrylate and SBS polymer chain
Connection probability, so as to improve the grafting rate of maleic anhydride and methyl methacrylate on SBS polymer, improve material and utilize
Rate；Contain organosilicon in another aspect crosslinking agent, it is possible to increase the viscosity of SBS polymer so that the adhesion effect of SBS polymer
More preferably, so as to strengthening the adhesion between SBS modifier and pitch.
(2) present invention, using hexamethylene and reactant as dispersed phase, is emulsified using water as continuous phase by high-speed stirred so that
Dispersed phase exists in a manner of molecule, and the modified SBS particle diameter prepared is small, is crushed without follow-up, convenient to be mixed with pitch,
And water as continuous phase by hexamethylene and air insulated, the volatilization of cyclohexane solvent can be efficiently reduced, be advantageous to ensure production
The health of personnel.
(3) content of type SBS is not less than 70% in SBS polymer of the invention, compared with star-shaped sbs, type SBS with
The compatibility of pitch is more preferable, if star-shaped sbs too high levels, is unfavorable for improving the compatibility between SBS modifier and pitch.
(4) emulsifying agent is not used in modified SBS powder preparing processes of the invention, is emulsified in a manner of high-speed stirred, made
Preparation Method is more environmentally-friendly, and utilization is recovered more easily in hexamethylene under the situation in the absence of emulsifying agent, advantageously reduces consumption of raw materials.
