The invention discloses a method for preparing a low temperature epoxy fatty acid branched-chain alcohol ester improver for biodiesel and application thereof. The method comprises the steps of taking natural oil and branched-chain alcohol as raw materials to react in the presence of a catalyst, and carrying out distilling, standing and layering on the product to obtain supernatant fatty acid branched-chain alcohol ester; and then mixing the fatty acid branched-chain alcohol ester with formic acid, adding an epoxidation catalyst, reacting while dropwise adding hydrogen peroxide, and carrying out standing, layering, neutralizing and dewatering on the product to obtain epoxy fatty acid branched-chain alcohol ester. The invention develops an epoxy fatty acid branched-chain alcohol ester improver aiming at the characteristics of biodiesel. The method has the following beneficial effects: by branching bonds of fatty acid ester and introducing a polar group onto the interior double bond structure of the fatty acid ester, the improver can be easily mixed with the biodiesel to form uniform solution, thus being beneficial to blocking further growth of solid crystals; and after different oil-based biodiesels and the improver are mixed, the low temperature fluidity of the biodiesels can be obviously improved, the condensation point and cold filter point can be reduced by 5-15 DEG C, the calorific value can be improved, and the viscosity can be reduced.
