Cold-rolled hot-dip aluminum-zinc-plated steel sheet with high lubricity and high corrosion resistance and manufacturing method thereof

The invention discloses a cold-rolled hot-dipped aluminum-zinc steel plate with high lubricity and high corrosion resistance and a manufacturing method thereof, and mainly solves the technical problems that the existing cold-rolled hot-dipped aluminum-zinc steel plate is poor in red rust resistance and is easy to become black after being stamped and rubbed. According to the technical scheme, the cold-rolled hot-dip aluminum-zinc steel plate with the high lubricity and the high corrosion resistance comprises a base plate, an aluminum-zinc coating covering the surface of the base plate and a chromium-free fingerprint-resistant film covering the surface of the aluminum-zinc coating, and the base plate comprises, by weight, 0.0050%-0.0070% of C, smaller than or equal to 0.035% of Si, 0.45%-0.65% of Mn, 0.02%-0.04% of P, smaller than or equal to 0.012% of S, 0.03%-0.07% of Alt, smaller than or equal to 0.003% of N, 0.03%-0.06% of Ti and the balance Fe. The balance is Fe and inevitable inclusion elements; the zinc
