| titleOfInvention | A kind of preparation method of road low temperature modification pitch |
| abstract | A kind of preparation method of road low temperature modification pitch, by 5~20 parts of chemical assistants, 80~95 parts of rubber powders are mixed, then mixing rubber powder is added into ultrasonic cumulative reactor, it is 1000~1500W by the power setting of radioactivation device, frequency is 10~30KHz, and 15~25s is to get activated rubber powder for activated processing；Then according to activated rubber powder: matrix pitch: the mass ratio 3: 6: 1 of SBS, SBS is added in the asphalt of melting, activated rubber powder is added in whipping process, maintain temperature at 165~175 DEG C, and under 3000~4000rpm/min rotating speeds, 30~50min of high speed shear, keep its blending uniform.Present invention process step is simple, and investment of production is few, shoddy activation modification it is efficient, can be prepared that quality is uniform, the superior advanced road modified pitch of stability, can effectively solve the problem of the low temperature modification temperature flowing of pitch. |
