The invention discloses a sound absorption
coating and a production method thereof. The sound absorption
coating is prepared from the following raw materials:
polyurethane,
emulsion,
slag wool fiber,water, a composite
coupling agent,
diatom ooze, expanded
perlite, a
levelling agent and a
defoamer. The sound absorption
coating has good sound absorption property; the coating is free of joints, highin decoration performance, excellent in
hardness, finish degree,
water resistance and
cracking resistance, excellent in stability, and high in
hardness; the
mechanical property of the coating is enhanced; the usage performance of the coating is more excellent; the adhesion and the friction resistance of the coating are improved; the density and the strength of the coating are increased; the condition that the coating is pulverized, cracked and stripped after being constructed is avoided; the coating is non-toxic and harmless, is free of adverse effects on the
human body and the environment, is applicable to
reverberation control spaces such as theaters, lecture rooms, conference rooms, swimming pools and gymnasiums, is also applicable to sound improvement environments such as restaurants,dining rooms, offices, airport waiting halls,
station waiting rooms, ship waiting rooms, shopping malls and exhibition halls, and can be used as a decorative sound absorption material applied to houses, villas, hotels, guesthouses and entertainment venues.
