Radial diffusion double-layer sound insulation ABS plate

Abstract

The invention discloses a radial diffusion double-layer sound insulation ABS plate, and belongs to the field of ABS plates. The radial diffusion double-layer sound insulation ABS plate comprises two ABS plate bodies and a sound insulation interlayer fixedly embedded between the two ABS plates, a plurality of uniformly distributed radial sound guide rods are fixedly embedded inside the sound insulation interlayer, and the radial sound guide rods are arranged in the ABS plates, on the one hand, the two sound insulation air layers can be formed on the two sides of each ABS plate body, so that the diffusion speed of sound in the ABS plate bodies is remarkably reduced, the sound insulation effect of the ABS plate bodies is remarkably improved, and on the other hand, when the sound is transmitted to the sound blocking gas rods, most of the sound can be diffused and transmitted towards the sound blocking gas rods in the radial direction along the trend of wide-bottom hard rods. Compared with the prior art, the direction that sound directly penetrates through the plates originally is changed, the sound is transmitted in the plates in the radial direction, part of the sound is blocked under the action of inert gas in the sound blocking gas rods, the decibel of the sound directly penetrating through the ABS plate bodies is effectively reduced, and the sound insulation effect is remarkably improved.

Description

technical field [0001] The invention relates to the field of ABS boards, in particular to a radially diffused double-layer sound-insulating ABS board. Background technique [0002] ABS board is an emerging material in the board industry. Its full name is acrylonitrile / butadiene / styrene copolymer board, which is the polymer with the largest output and widest application. It organically unifies the various properties of PS, SAN, and BS, and implements the excellent mechanical properties of toughness, hardness, and rigid phase balance. Excellent impact strength, good dimensional stability, dyeability, good molding and machining, high mechanical strength, high rigidity, low water absorption, good corrosion resistance, simple connection, non-toxic and tasteless, with excellent chemical properties and Electrical insulation properties. It can withstand heat without deformation, and also has high impact toughness under low temperature conditions. It is also a hard, non-scratch, ...
