Abstract

The invention discloses a diatomite environment-friendly acoustical board, relates to the technical field of acoustical boards, and mainly aims to solve the problem that most of existing acoustical boards adopt gypsum boards and are poor in water resistance. The acoustical board comprises the following raw materials: resin, diatomite, polypropylene fibers, bamboo charcoal fibers, glass fibers, attapulgite clay, modified mica powder, coarse stone powder, sodium alginate, modified fly ash, a polyolefin elastomer, water, an ethylene-vinyl acetate copolymer, lignocellulose, chitosan, a rare earthcatalyst, a water repellent, a flocculant, a binder, a flame retardant and a lubricant. The diatomite is added, so that the acoustic board has good extensibility, high impact strength, tensile strength, tearing strength, light weight, good internal grinding performance, good high-pressure strength and other excellent effects, the resin and the polyolefin elastomer are added, so that good elasticity is achieved, the sound absorption capacity of the acoustic board can be improved, and meanwhile toughness is enhanced.

Description

technical field [0001] The invention relates to the technical field of sound-absorbing panels, in particular to a diatomite environment-friendly sound-absorbing panel and a preparation method thereof. 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] Nowadays, most sound-absorbing panels in many places use gypsum boards. However, gypsum boards have poor water resistance and are not suitable for use in humid environments. They are p...
