A hydraulic oil composition, consisting of a glyceride selected from one or a mixture of more than one of glyceride borate, glyceride acetate, glyceride propionate and glyceride lactate; alcohols; acids and water, wherein in terms of both the alcohols and acids, only the alcohols can be comprised, or only the acids can be comprised, or both the alcohols and acids can be comprised, and wherein the amount of water is 0 wt%. The hydraulic oil composition has low-temperature flame retardant performance, a high flash point, a high auto-ignition temperature and a low pour point, still has relatively good flowability under a low-temperature environment and a high viscosity index, and has relatively excellent rust-proof and anti-oxidization performance for ferrous and nonferrous metals. |
