The invention discloses a copper phthalocyanine thin polymer film sound-absorbing material and a preparation method thereof; the sound-absorbing material is composed of an electricity-conducting high polymer formed by copper phthalocyanine derivatives, nanometer additives, auxiliary film-forming agents and a carrier material, and forms a unity according to change mode of electrical conductivity. The sound-absorbing material can achieve good sound-absorbing effect in a sound wave broadband range (125Hz-4000Hz), and the average sound-absorbing coefficient is more than 0.5, and the maximum sound-absorbing coefficient is 0.95; the thickness is thin and the weight is light, the thickness of the film is 0.1-0.5mm, and the weight of the copper phthalocyanine thin polymer film sound-absorbing material per square meter is about 150-400g.
