| titleOfInvention | A kind of latex modified asphalt composition grain and preparation method thereof |
| abstract | The invention discloses a kind of latex modified asphalt composition grain and preparation method thereof, latex modified asphalt composition grain of the invention, including following component：High softening point bitumen particle 80wt%~94wt%；Latex 5wt%~20wt%；Wherein, described high softening point bitumen particle, using high softening point bitumen I as nuclear phase, outer layer covers high softening point bitumen II, high softening point bitumen II and high softening point bitumen I softening point difference are 10 ~ 25 DEG C.Preparation method is as follows：Latex is uniformly sprayed onto on high softening point bitumen composition, infiltration a period of time is stood, through vacuum freeze drying, obtains modified asphalt composite particle.Modified asphalt composite particle of the present invention has higher softening point, and high-temperature behavior is excellent, and preparation method is simple, can persistently be played a role under the conditions of the drillng operation of wide temperature range in deep layer drilling well, plays good closure and filtrate reducing effect. |
