The invention relates to the field of power battery packaging, in particular to a preparation method of an organic silicon foaming gasket for power battery box body packaging. The preparation method of the organic silicon foaming gasket for power battery box body packaging comprises the steps of conveying two prepared components including organic silica gel A and organic silica gel B to a channelA and a channel B correspondingly, wherein the mass ratio of the two components is that A:B is from 1:20 to 20:1; keeping the temperature of the organic silica gel A and the organic silica gel B at apretreatment working temperature to prepare well before dispensing; setting dispensing parameters, and programming to control the dispensing parameters according to the shape of a battery pack to be packaged; and starting a dispenser for dispensing, and curing the surface skin layer at room temperature. According to the preparation method, the flame retardant grade reaches the V-0 grade; and the skin layer completely covers the surface of a sealing gasket, so that the permanent compression deformability is small, and the sealing gasket is still able to reach the IPX8 waterproof level after being subjected to high-temperature high-humidity environment, high and low temperature impact and high and low temperature salt spray several hours later.
