Description
Affiliated field
The present invention relates to a kind of polymer modified asphalt and preparation method thereof, specifically relate to a kind of powder styrene butadiene rubber high molecular polymer carries out modification to matrix pitch as properties-correcting agent asphaltic products. and preparation method thereof that utilizes.
Background technology
By introducing in " production of petroleum pitch and application " book that people such as Zhang Deqin write, Sinopec press publishes, domestic production styrene butadiene rubber modified asphalt technology mainly contains three kinds at present.The one, solvent method: solid styrene-butadiene rubber(SBR) is cut into small pieces, joins in the benzene class organic solvents such as toluene and dissolve, solvent is steamed after miscible with heated bitumen again, produce styrene butadiene rubber modified asphalt.The 2nd, emulsion method: styrene butadiene rubber latex is joined in the heated bitumen by mechanical stirring directly miscible, again moisture is steamed, produce styrene butadiene rubber modified asphalt; The 3rd, the calendering process method: by mixing facilities or two roller mill slice, the preparation masterbatch, and by the high speed shear mixing tank SBR blob of viscose directly is blended into and produces styrene butadiene rubber modified asphalt in the heated bitumen.
All there is certain defective in above-mentioned preceding two kinds of technologies: introduce noxious solvents such as toluene when solvent method is produced in the system, can cause serious environmental to pollute and to operator's murder by poisoning, and still contain a small amount of aromatic solvent in the product after reclaiming, influence the high temperature performance of product, cause the various diseases on road surface easily; Emulsion method can produce a large amount of water vapors when producing, cause " bumping " still that overflows easily, production endangers safety, simultaneously, latex stops up shower nozzle, etching apparatus easily, make troubles to production, and residual moisture can influence the high temperature performance of modifying asphalt in the product, has weakened the adhesivity with building stones, influences the pavement performance of product; When producing, calendering process need use mixing facilities or two roller mill and high speed shear mixing tank, the equal more complicated of production technique and equipment, production cost height.
