Abstract

See full text

A particulate sound absorption board and its preparation method. The said particulate sound absorption board consists of binding agent and sound absorption particle; the external surface of sound absorption particle is covered with a layer of binding agent, and the angularity coefficient of particle covered with binding agent is less than 1.3; the said sound absorption particle consists of skeleton particle and filling particle, in which the former is used for sound absorption board skeleton, and the latter flows into the pore between skeleton particles to form sound absorption pore, and the average diameter of cross section of sound absorption pore is 0.07 mm. The two-stage manufacturing technology (i.e. coating, curing and then shaping) is adopted for the said preparation method to prevent the pore between particles from being blocked by excess binding agent, and further improve the angularity coefficient of particle.
