A preparing process of Low-e bent laminated glass is disclosed. The process includes steps of a) subjecting Low-e glass substrates to edging by adopting a horizontal dual straight edge machine through a synchronous belt, putting into a cleaning machine and cleaning, b) putting the cleaned glass onto a roller way, conveying into a convective tempering furnace through the roller way, and performing one-stage heating treatment, c) discharging the heated glass out of the furnace, conveying into a bent wind grid and bending along with bends of a conveying roller way and the wind grid by means of self weight, d) laminating the cleaned two or more bent tempered glass sheets in a dust-free sealed laminating chamber, e) putting the laminated glass in the step d) into a roller press and removing air bubbles, and f) allowing the bent glass subjected to secondary heating in the step e) to slowly pass through a bent glass roller press to remove air bubbles. The process is simple, and the produced bent laminated glass is high in tensile strength, bending strength and shock strength, beautiful in appearance and clear.
