Although the materials have certain sound insulation and absorption effects, the materials cannot achieve the sound insulation effect with higher requirements due to the defects of the materials, and even the sound insulation performance is reduced along with the prolonging of the service life. Such as: in the use process of the rubber product and the rubber product sound insulation sheet, permanent shrinkage deformation occurs on the rubber product and the rubber product part along with the time, so that cracks occur on a cement wall and the like on the outer side of the singing sound sheet. EPS (EPS) (XPS), XPE (IXPE), polyurethane and other materials can generate related harmful substances in the production process, meanwhile, the products are difficult to degrade and easy to form white pollution, EPS (XPS) is polystyrene, monomer benzene can be separated out after the materials are heated, and benzene is an internationally recognized known carcinogen; the combustion toxicity of polyurethane is the most toxic of the heat insulating materials, so that it is not a green healthy material because it has an adverse effect on human body as an indoor material of a house. In addition, EPS (XPS) formed plates have poor toughness, impact resistance and permanent deformation to a large extent after repeated impact compression, and the sound insulation and absorption effects are also reduced to a large extent.
