FIELD: process engineering.
SUBSTANCE: acoustic panel is made by application of thin soundproof coating on acoustic plate of the bed. One or several fillers, fibrous filler, binder and water are used to get the pulp. Thickener and water are used to prepare thickener solution. To break the fibrous filler and to get the smooth coating a portion of the pulp and thickener solution are mixed under high shear forces. Coating is applied on bed plate, coated plate is cut and dried to obtain coated acoustic panel. Panel coating surface has no visible symptoms of mineral cotton granules. Optionally, said pulp is the pulp portion used for production of bed plate. In compliance with the other options, used can be acoustic panel fine particles or dust resulted from cutting or shaping the bed plate or coated panels.
EFFECT: perfected method.
