This paper mainly studies the preparation of a new type of sound-insulation coating for building floors,including material selection,preparation process and performance testing.The results show that the weighted impact sound pressure level improvement of the sound-insulating coating is ⊿ Lw=12 dB,the combustion performance reaches A2 level,and the environmental performance meets the requirements of GB18582-2020 for interior wall coatings.It provides theoretical basis and practical guidance for the application of building floor sound-insulation coatings.
