The invention discloses an alkaline battery negative electrode gel preparation method which specifically comprises the following steps: 1) under the protection of nitrogen, adding unsaturated carboxylic acid monomer, organic solvent and dispersing agents to a reactor, stirring the mixture and heating the mixture to the temperature of 55-80 DEG C; 2) adding a solution comprising an initiator and a solution comprising a cross-linking agent to a reaction system in the step 1) in a dropping manner, and conducting reacting for 2-10 hours; and 3) after the reaction is finished, carrying out suction filtration and drying, and thus the alkaline battery negative electrode gel is obtained. The obtained alkaline battery negative electrode gel is uniform in crosslinking. Meanwhile, the invention also provides the alkaline battery negative electrode gel obtained by using the preparation method. When the alkaline battery negative electrode gel is applied to the negative electrode of an alkaline battery, the obtained gel negative electrode suspension zinc powder is strong in capability and good in impact resistance of the alkaline battery. Meanwhile, by using the alkaline battery negative electrode gel, the production process of the battery is allowed to be simper, and the battery processing difficulty is reduced.
