The invention discloses a sound-absorbing and noise-reducing flame-retardant material and a preparation method thereof, and relates to the technical field of sound-absorbing flame-retardant material processing. The material comprises 5-10 parts of carbon fiber, 15-30 parts of regenerated cotton fiber, 2-6 parts of polyester fiber, 15-20 parts of low-melting-point thermoplastic fiber and 20-30 parts of non-woven fiber. The preparation method comprises the steps of opening treatment, primary needling, dipping and drying, baking, washing and drying, secondary needling, steaming, die assembly forming, cutting and the like steps. The invention further discloses a dipping and drying all-in-one machine for flame retardant dipping and drying treatment. Compared with the prior art, the material hasexcellent sound-absorbing and flame-retardant performance and good thermoplastic forming performance, the semi-finished product of the composite felt subjected to secondary needling is further fluffyby steam blowing, so that the sound-absorbing performance is improved, and meanwhile, the material has a certain shock-absorbing effect.
