The invention relates to the technical field of oxygen production equipment, in particular to a composite material for a silencing structure on the inner wall of a dispersion type oxygen generator and the silencing structure, the composite material comprises an SBS first adhesive layer, an IIR rubber layer, an SBS second adhesive layer and an ACM rubber layer which are sequentially spliced, and a plurality of PP hard plastic circular rings arranged on the end face of the ACM rubber layer; the hard plastic circular ring made of the PP material is sleeved with a wedge-shaped PP block made of the PP material, and the surface of the wedge-shaped PP block is coated with a resin nanometer coating. And the extension surface with a smaller area in the two parallel extension surfaces in the wedge-shaped PP block is connected with the PP hard plastic circular ring. Due to the fact that the composite material layer body is provided with the IIR rubber layer and the ACM rubber layer, the composite material layer body has
