Nano modified water-base multifunctional sound-absorbing paint and preparation method thereof

The invention discloses a nano modified water-base multifunctional sound-absorbing paint and a preparation method thereof. The paint is composed of the following components in parts by weight: 28-38 parts of emulsion, 2-10 parts of pigment, 30-45 parts of filler, 15-25 parts of water, 4-8 parts of flame retardant and 2.25-5.43 parts of assistant. By optimizing the paint system structure, the polymer and filler are selected, modified and proportioned to ensure the basic mechanical properties and sound-absorbing function, and the paint has high-value service properties, such as thermal insulation, moisture resistance, fire resistance, aging resistance, fouling resistance, sterilization, air purification and the like, and is especially suitable for rooms and other occasions with higher environmental requirements.
