Example Embodiment

[0041] Example 1:

[0042] See figure 1 A double-layer sound insulation ABS plate, including two ABS plates 11 and fixed mounting between the two ABS plates 11, and the inside of the sound absorbing layer 12 fixed inlaid inlay has multiple allocate radial guides. The sound rod, the both ends of the radial vapor lever extends and is inlaid at one end of the two ABS plates 11 to each other.

[0043] See figure 2 The radial vapnetic rod includes two flap balls 21 and a loot bar 22 connected between the two loot balloon 21, and the external end of the lobe 22 fixedly connected to a plurality of uniform distribution of aquaryagnetic rod 3, the resistance The tonic ball 21 includes two blocks 211 that are fixedly coupled to each other and a built-in resort 212 placed between the two roller spheres 211, and the innermost internally filled in the two roller space 211 is filled with an inert gas, the inert gas is compressed. And the compression multiple is 2-3 times, and the plurality of f...

Example Embodiment

[0047] Example 2:

[0048] See Image 6 The loot balloon 21 is placed with a high rebound balloon, and the high rebound balloon includes an outer ventilation ball housing 61, located at the center of the outer pass balloon housing 61, and a plurality of connections in the outer pass balloons 61 inner wall and positioning The support rod 63 between the outer surface of the core 62, the outer pass balloon shell 61 is the elastic multi-through-hole structure, so that the inert gas in the lunar balloon 21 can penetrate into the high-rebound air ball, the support rod 63 is a high toughness material Become, in this embodiment, the high-back balloon can replace the built-in resort 212 in Example 1, while other structures are consistent with Example 1, when it is accidentally impacked or extruded, when the flamepin 211 deform When the high-back balloon is squeezed, the internal inert gas is squeezed, and the buffer effect generated by the deformation of the pinch hemisphere 211 is better c...

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, ...
