Problems solved by technology

In the present invention, the cement-based composite sound-absorbing material is processed through steps such as raw material stirring, layered material distribution, mold clamping and pressurization, curing, cutting, etc. Although the sound-absorbing material has high noise reduction coefficient, fire prevention and corrosion resistance, it can be directly used as a sound-absorbing sound-absorbing material. barrier, but the physical properties of the sound barrier sound-absorbing panels are heavy in quality, low in strength, low in compressive strength and bending fracture load strength

Abstract

The invention relates to a lightweight acoustic panel containing a rare earth catalyst, and a preparation method thereof. The lightweight acoustic panel is composed of raw materials of: Portland cement, fly ash, plaster powder, polypropylene fiber, re-dispersible latex powder, expanded perlite, a foaming agent, and a rare earth catalyst. According to the invention, during an acoustic panel preparation process, the rare earth catalyst is adopted, such that inorganic materials are sufficiently aerated, and a reaction is carried out. Therefore, acoustic panel quality is ensured, the panel is light and does not deform. The prepared acoustic panel is advantaged in light weight, high strength, substantial sound-absorbing effect, good water resistance, and aging resistance.

Description

technical field [0001] The invention relates to a building decoration material, in particular to a sound-absorbing board for installation on a wall. Background technique [0002] Sound-absorbing panels refer to plate-shaped materials with sound-absorbing and noise-reducing effects, which are mainly used in theaters, concert halls, museums, exhibition halls, libraries, interrogation rooms, galleries, auction halls, gymnasiums, lecture halls, multi-functional halls, and hotel lobbies Hospitals, shopping malls, schools, piano rooms, conference rooms, studios, recording studios, KTV private rooms, bars, industrial plants, computer rooms, home noise reduction and other places that require high acoustic environment and high-end decoration. [0003] According to the production materials, the sound-absorbing panels are divided into five categories: wooden sound-absorbing panels, mineral wool sound-absorbing panels, fabric sound-absorbing panels, polyester fiber sound-absorbing panel...
