The invention relates to a composite heatable sealing profile and a preparation method thereof. The sealing profile is matched with a sealing tape mounting clamping groove of a cabin door and comprises an inner-layer silicone rubber base body and an outer-layer polyester fabric reinforcing layer wrapping the inner-layer silicone rubber base body, and a hollow sealing extrusion cavity is formed in the inner-layer silicone rubber base body; a heating rubber layer is arranged in the inner-layer silicon rubber base body and at the position of a sealing contact surface of the profile, is of a strip-shaped structure and is connected with an external power supply; the section of the sealing profile is Q-shaped, omega-shaped or U-shaped; and the heating rubber layer is prepared from the following raw material components: a silicon rubber base material, a conductive carbon black filler, a flame retardant, a carbon nanotube and other auxiliaries. The sealing tape solves the problem that in the prior art, an airplane cabin door sealing tape cannot effectively prevent ice and remove ice.
