The invention discloses a low temperature antistatic powder coating for automobile oil filling pipes. The powder coating is prepared from the following raw materials by mass: 35-75 parts of bicomponent polyester, 3-7 parts of a curing agent, 0.2-0.5 part of a catalyst, 5-15 parts of conductive metal powder, 0.3-0.5 part of a defoaming agent, 15-20 parts of barium sulfate, 5-15 parts of ceramic clay, and 1-2 parts of a leveling agent, wherein the bicomponent polyester comprises 15-35 parts of polyester A, and 20-40 parts of polyester B; the polyester B is acrylic monomer modified saturated polyester resin, and has an acid value of 30-37mgKOH/g and viscosity of 3000-6000mPa.s/200DEG C. The invention also discloses a method for preparation of the low temperature antistatic powder coating for automobile oil filling pipes. The low temperature antistatic powder coating provided by the invention has the technical effects of low curing temperature, green and environment protection and low resistance, and avoids generation of electrostatic spark between oil filling pipes and oil guns.
