Abstract

A novel acoustic material for construction comprises the following components by weight: 15-20 parts of high density polyethylene, 10-15 parts of hollow glass beads, 4-7 parts of kaolin, 2-6 parts of silicon carbide, 3-9 parts of magnesium oxide, 3-7 parts of wetting agent, 6-10 parts of mica powder, 6-12 parts of organosilicone modified epoxy resin, 3-8 parts of mixed solvent, 6-10 parts of sabina chinensis wood chips and 5-10 parts of attapulgite. According to the above-mentioned technical scheme, the acoustic material for construction of the invention is capable of filtering a large amount of noise in the environment and has a very good effect on the low-frequency noise.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a sound-absorbing material for building. Background technique [0002] Noise prevents people from resting, studying and working normally, and also interferes with the sounds people want to hear. Noise can damage the sensory hair cells of the ear's sound-sensing organ (the cochlea). Once the sensory hair cells are damaged, they can never be restored. Sensory hair cells with high frequency are most vulnerable to noise damage. In the field of construction, noise is also a great hazard. In building houses, noise reduction treatment is also required to improve people's comfort. Sound-absorbing building materials are people's first choice. Therefore, it is of practical significance to develop a new type of sound-absorbing material. Contents of the invention [0003] The purpose of the present invention is to propose a new type of sound-absorbing material for construction. The tec...
