Abstract
The invention relates to an epoxidized SBS (styrene butadiene styrene) modified asphalt and its production process. According to the invention, epoxidized SBS is adopted as a modifying agent to modify asphalt so as to prepare the epoxidized SBS modified asphalt. The epoxidized SBS modified asphalt consists of, by weight: 100 parts of matrix asphalt, and 2-7 parts of epoxidized SBS. The epoxidized SBS and the matrix asphalt have good compatibility, the asphalt performance can be significantly improved and the storage stability can be enhanced. The production process is simple, and is easy to realize industrialization.
Description
Technical field
The present invention relates to a kind of epoxidized SBS modifying asphalt and production technique thereof, belong to the polymer-modified asphalt field, be specifically related to a kind ofly take epoxidized SBS as properties-correcting agent pitch be carried out modification and technique.
Background technology
Along with deepening continuously of asphalt applications, it is found that common pitch has been difficult to adapt to day by day harsh environment and technical requirements, practice shows, by certain technique, in pitch, add some properties-correcting agent, make modifying asphalt, can significantly improve the use properties of pitch.Polymer modifiers is most widely used, and wherein, styrene-butadiene-styrene block copolymer (SBS) can improve again the anti-cold cracking of pitch owing to can improve the high-temperature stability of pitch, uses and is promoted rapidly.
Want the good polymer modified asphalt of processability, must at first the properties-correcting agent Uniform Dispersion be dissolved in the matrix pitch, make stable homogeneous system.In fact, because the consistency of most of polymer modifiers and pitch is very bad, after polymkeric substance joins in the matrix pitch, be easy to occur segregation phenomenon, affect the modified effect of polymkeric substance, and this problem never obtain satisfactory solution.
SBS is a kind of preferably polymer modifiers, but SBS is non-polar polymer, and is poor with the matrix pitch consistency of polarity.Chinese patent CN1365986A (a kind of method that improves SBS and pitch compatible stability) adopts chemical graft process forming section polar group on SBS, reach the compatible stable effect of SBS and pitch, its compound that is used for grafting mainly is double bond containing acid anhydrides series compound.Chinese patent CN101041708A (a kind of method of synthesizing terminal amido SBS and the application in modifying asphalt thereof) discloses the preparation method of the aminated styrene/butadiene/styrene ternary block polymer of a kind of end group (SBS), and be applied to modifying asphalt, can obviously improve asphalt performance, reduce the segregation degree, thereby improve stability in storage.
Summary of the invention
The object of the present invention is to provide a kind of epoxidized SBS modifying asphalt and production technique thereof.Be specifically related to a kind ofly take epoxidized SBS as properties-correcting agent pitch be carried out modification and technique.
For realizing such purpose, the technical solution used in the present invention is:
The invention provides a kind of epoxidized SBS modifying asphalt and production technique thereof, it is characterized in that it consists of in weight part:
100 parts of matrix pitches
2～7 parts of epoxidized SBS
Preferably, epoxy group(ing) quality mark is 1～12% in the described epoxidized SBS.
Preferably, the preparation method of described epoxidized SBS is: take toluene as solvent, adopt formic acid and hydrogen peroxide that SBS is carried out the original position epoxidation modification.
The present invention also provides a kind of production technique of epoxidized SBS modifying asphalt, may further comprise the steps:
(1) preparation of epoxidized SBS: SBS and toluene are added in the reactor, after SBS dissolves fully, add quantitative formic acid, under 60～80 ℃ of temperature, stir, drip quantitative hydrogen peroxide, react 1～5h, make the epoxidized SBS of solution state.
(2) preparation of epoxidized SBS modifying asphalt: under 100～120 ℃, be preheated to matrix pitch fully mobile, the epoxidized SBS that adds the toluene dissolving that makes in the step (1), stir, slowly be warming up to 175 ℃, reaction 1～2h, vacuumize the removal solvent, namely get the epoxidized SBS modifying asphalt.
The beneficial effect that the present invention has:
The present invention relates to a kind of epoxidized SBS modifying asphalt and production technique thereof, take epoxidized SBS as properties-correcting agent pitch is carried out modification, preparation epoxidized SBS modifying asphalt.The polarity of the nonpolar SBS product epoxidized SBS after through the modification of original position epoxidation process is strengthened, and has improved the consistency with the polarity matrix pitch, can obviously improve asphalt performance, improves stability in storage.
