The invention relates to a coating for preventing intermetallic bonding, in particular to a water-based high-temperature-resistant titanium-steel anti-bonding coating and its use in the preparation process of titanium ingot. The water-based high-temperature-resistant titanium-steel anti-bonding coating of the invention includes the following components in parts by weight: 50-150 parts of water-based film-forming agent, 0-50 parts of Zn powder, 400-450 parts of Al.sub.2O.sub.3 powder, and 250-350 parts of talcum powder. The coating of the invention can avoid the bonding reaction with a roller or a winch of the steel equipment in the rolling or perforation process of a titanium tube at 900 C., so as to improve the yield and the production efficiency of titanium material processing. Moreover, the process is simple and easy to operate, the coating is environment-friendly and pollution-free, and easy to prepare.
