摘要

Isobutyltriethoxysilane surface organic grafted layered double hydroxide (OLDH) was prepared and utilized to improve the ultraviolet aging resistance of bitumen. The results of Fourier transform infrared (FTIR) and Static contact angle showed that isobutyltriethoxysilane has been grafted on the surface of LDH and the hydrophilic property of OLDH was observably weakened. The storage stability test indicated that OLDH had better compatibility and stability in bitumen compared with LDH, which was due to the decrease of hydroxyl and the introduction of organic group on the surface of LDH after isobutyltriethoxysilane organic grafting modification. Furthermore, OLDH modified bitumen showed more excellent high-temperature behavior than that of LDH modified bitumen. After ultraviolet aging, the performance of bitumen seriously deteriorated and the colloid stability notably decreased. Comparing with LDH, OLDH exhibited better in inhibiting the performance deterioration and gelefication of bitumen after ultraviolet aging, which implied that isobutyltriethoxysilane surface organic grafting modification was beneficial to strengthen the improvement of LDH on the ultraviolet aging resistance of bitumen.
