Static electricity preventing method of foam gun

The invention relates to a static electricity preventing method of a foam gun, and mainly solves the problem of incapability of removing static electricity of the foam gun in the prior art. The static electricity preventing method of the foam gun uses an antistatic firefighting hose to realize the antistatic performance of the foam gun; the firefighting hose consists of a static conducting rubber lining layer and an antistatic flax braid layer; the antistatic flex braid layer is wrapped at the outer side of the static conducting rubber lining layer; the static conducting rubber lining layer consists of a rubber material and a static conducting material; the volume resistivity of the rubber lining layer is lower than 106 omega.m; the antistatic flax braid layer consists of a flax braided fabric and an electric conducting fiber; and the unit volume resistivity of the antistatic flax braid layer is within 106-108 omega.m. The static electricity preventing method of the foam gun preferably solves the problem, and can be applied to the static electricity prevention of the foam gun.
