Abstract

The invention discloses a building sound insulation material and a preparation method thereof, the building sound insulation material comprises the following components by weight: 66-72 parts of polyethylene, 8-12 parts of organic fiber, 5-12 parts of coal gangue powder, 5-12 parts of fly ash, 8-10 parts of poly trimethylene carbonate, 5-8 parts of montmorillonite and 0.05-1 part of sodium humate. The invention also provides the preparation method of the building sound insulation material, and the method comprises the following steps: (1) weighing 66-72 parts by weight of polyethylene, 8-12 parts by weight of organic fiber, 5-12 parts by weight of coal gangue powder, 5-12 parts by weight of fly ash, 8-10 parts by weight of poly trimethylene carbonate, and 5-8 parts by weight of montmorillonite; (2) putting the component into a high pressure homogenizer, stirring for 30min at 65-70 DEG C under 21.5-22MPa; and (3) sequentially adding the 0.05-1 part of sodium humate, stirring evenly, and firing 2-3 hours at 780-850 Deg C to obtain the building sound insulation material.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a sound-insulating material for building and a preparation method thereof. Background technique [0002] Sound insulation material refers to a class of materials, components or structures that can block sound transmission or reduce transmitted sound energy. It is characterized by heavy weight and high density. Commonly used traditional sound insulation materials include steel plates, lead plates, concrete walls, brick walls, etc. . [0003] At present, noise has become a major environmental pollution, and the acoustic environment of buildings has attracted more and more attention. It is one of the most commonly used and most basic technical measures for noise control today to treat buildings with sound absorption, sound insulation, and shock absorption by selecting appropriate materials. [0004] Sound insulation refers to the isolation, isolation, separation, etc. of sound or...
