Abstract

The invention provides a novel environment-friendly acoustic insulating building material and a preparation method thereof. The novel environment-friendly acoustic insulating building material is prepared from the following components: kaolin ore slurry concentrate, polyethylene resin, phenolic resin, magnesium oxide, fly ash, ceramic powder, gypsum powder, sawdust, plant fibers, polyethylene glycol, toughening filler, an antioxidant, a puffing aid and water. The preparation method of the novel environment-friendly acoustic insulating building material disclosed by the invention has the advantages of simple production process and low possibility of deformation when being pressed; low carbon, and environment friendliness are realized by adopting a variety of domestic and industrial wastes;the novel environment-friendly acoustic insulating building material can be widely applied to the field of building materials, and the utilization rate is improved; in addition, the building materialprepared by the invention has the characteristics of light weight, high pressure resistance and good sound insulation and thermal insulation effects.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a novel environment-friendly and sound-insulating building material and a preparation method thereof. Background technique [0002] At present, noise has become a major environmental pollution, and the acoustic environment of buildings has attracted more and more attention. The selection of appropriate materials for sound absorption and sound insulation of buildings is the most important aspect of building noise control engineering. One of the most basic technical measures commonly used. The interior surfaces of buildings include floors, walls and ceilings. The traditional decoration materials are stone, slab and plaster. Due to the physical properties of these materials, sound waves are strongly reflected. If you have a meeting, listen to a report or enjoy music in this kind of space, although the audience feels that the sound is very loud, the sound qu...
