| description | The utility model discloses a?straw polymer composite acoustic board. The straw polymer composite acoustic board comprises a square substrate formed by a straw type plant fiber polymer material; through holes formed from the upper surface of the substrate to the lower surface and through the whole substrate and filled with an acoustic absorption filler; main acoustic absorption holes arranged on the front surface of the substrate and communicated with the through holes; a male fastening structure arranged on one side surface of the substrate; a female fastening structure correspondingly cooperated with the male fastening structure and arranged on the opposite side surface of the substrate; and side acoustic absorption holes communicated with the through holes and arranged on the two side surfaces of the substrate. The straw polymer composite acoustic board has features of simple and reasonable structure, and low manufacture cost. The straw polymer composite acoustic board has the following advantages that: 1 |
