The invention discloses a Zr and Ba-containing zinc alloy for hot dip galvanizing of aluminum alloys at low temperature and a processing method thereof. The Zr and Ba-containing zinc alloy comprises the following components by weight: 0.8-1.0wt% of Ba, 0.5-0.8wt% of Zr, 0.4-1.0wt% of In, 1.0-2.0wt% of Mn, 0.2-0.5wt% of V, 1.4-1.8wt% of Bi, and balance of zinc. The development of zinc alloys for for hot dip galvanizing of high-quality aluminum materials is facilitated, and the Zr and Ba-containing zinc alloy has a promoting effect on upgrading of China's independent research and development ofhigh-quality new materials and occupying of the international market.
