Water-based single-component interior wall damping sound-absorbing coating and preparation method thereof

The invention belongs to the technical field of coatings, and particularly relates to a water-based single-component interior wall damping sound-absorbing coating and a preparation method thereof. The water-based single-component interior wall damping sound-absorbing coating is prepared from the following raw materials in parts by weight: 20 to 30 parts of plant fiber polypropylene composite material emulsion with an interpenetrating network structure, 8 to 12 parts of coated porous hydrophobic expanded perlite, 35 to 45 parts of pigment and filler, 0.5 to 0.7 part of cellulose ether, 0 to 4.5 parts of auxiliaries and 15 to 30 parts of water, wherein the sum of the parts by weight of all the components is 100. The production process of the water-based single-component interior wall damping sound-absorbing coating is simple and easy to operate, the labor cost and the time cost are reduced in a large range, and the water-based single-component interior wall damping sound-absorbing coating is very suitable for l
