Abstract
The invention discloses an odorless waste tire rubber powder modifying agent easy to melt. The odorless waste tire rubber powder modifying agent easy to melt has the advantages that the novel odorless waste tire rubber powder modifying agent easy to melt solves the problems that in the prior art, rubber powder modified asphalt releases pungent stink in the production and construction process, the production temperature is 180-190 DEG C and is relatively high, energy consumption and viscosity are high, a high temperature is also needed in construction, and rubber powder serves as the core of rubber powder modified asphalt and is the reason for the high temperature and stink in production and construction; the odorless waste tire rubber powder modifying agent easy to melt is prepared by carrying out desulfuration treatment on common rubber powder and carrying out pre-soaking with a solvent, and diffusion of stink is greatly relieved when the modifying agent is used for producing rubber modified asphalt; besides, the viscosity of rubber modified asphalt is effectively reduced under the same condition, so that the production and construction temperature is reduced, energy consumption is reduced accordingly, cost is reduced, and harm to the environment is relieved.
