The invention discloses a preparation method of an aluminum alloy bar with high temperature resistance, relates to a preparation method of an aluminum alloy bar with high temperature resistance, and aims to solve the problems that an existing 2-series aluminum alloy bar is easy to break in a high-temperature environment and cannot meet use requirements. The high-temperature resistance of the 2-series alloy bar is improved through factors such as the solid solution treatment temperature, the solid solution heat preservation time, the aging temperature and the aging heat preservation time, the bar with the diameter ranging from 60 mm to 120 mm is produced through the unique chemical component proportion and the reasonable technological process, the surface quality, the straightness and the room-temperature strength are excellent, most importantly, the excellent high-temperature resistance is achieved at the same time, and the high-temperature resistance of the 2-series alloy bar is improved. The high temperatur
