The invention discloses a macromolecule environment-friendly elastic sound-insulating material, which, in parts by weight, comprises the following components: 10-20 parts of acryl-based elastomers, 5-15 parts of styrene-based elastomers, 40-120 parts of fillers, 1-15 parts of plasticizer, 2-10 parts of auxiliary. The polymer environment-friendly elastic sound insulation material has the advantages of high density, high strength, high flexibility, high sound insulation, high environmental protection and excellent high and low temperature resistance. The invention also discloses a preparation method of a macromolecule environment-friendly elastic sound-insulating material, comprising the following steps: premixing the styrene-based elastomer and the plasticizer in a dispersing machine, and putting the obtained mixture and the propylene-based elastomer into a dense Melt and mix evenly in the mill, then put in other components for melting, and transport the plasticized material to a single-screw extruder. After extrusion, extrusion, stretching and shaping, the polymer environmentally friendly elastic sound insulation material is obtained . The operation method is simple, the cost is low, and it is suitable for industrialization promotion. |
