Environment-friendly light building sound insulating material

Abstract

The invention discloses an environment-friendly light building sound insulating material which is prepared from the following raw materials in parts by weight: 10-20 parts of coal ash, 5-12 parts of coal gangue powder, 5-10 parts of asbestos wool, 7-15 parts of hollow ceramic microspheres, 5-7 parts of a thermoplastic phenol resin, 2-6 parts of an ethylene-propylene-diene monomer, 5-9 parts of a PVC resin, 5-11 parts of polyethylene, 1-4 parts of a plasticizer, 1-3 parts of an adhesive, 2-5 parts of a waterproof agent, 6-10 parts of nano carbon black, 9-11 parts of a polystyrene foam plastic and 0.3-0.6 part of a foaming agent. The hollow ceramic microspheres of the material have reflection and scattering functions on sound waves, so that noise can be effectively reduced; in addition, dueto addition of the asbestos wool, the thermoplastic phenol resin, the ethylene-propylene-diene monomer, the PVC resin, the polyethylene and the polystyrene foam plastic, the sound wave reflection andscattering properties can be further improved, so that the building sound insulating material is light in weight, convenient to mount, good in environment protection effect, applicable to buildings and the like, long lasting in noise reduction effect and free of indoor environment pollution.

Description

technical field [0001] The invention relates to the field of building materials, in particular to an environmentally friendly and lightweight building sound insulation material. Background technique [0002] Sound insulation material refers to a material, component or structure that isolates, isolates and separates the noise transmitted in the air. For sound insulation materials, in order to weaken the transmitted sound energy and block the transmission of sound, they cannot be as porous, loose, and breathable as sound-absorbing materials. On the contrary, their materials should be heavy and dense, such as steel plates, lead plates, brick walls, etc. class material. The material requirement of the sound insulation material is dense without pores or gaps; it has a relatively large weight. Because this kind of sound insulation material is dense, it is difficult to absorb and transmit sound energy and has strong reflection energy, so its sound absorption performance is poor. ...
