Example Embodiment

[0022] Example

[0023] Reference Figure 1-3 As shown, this embodiment discloses a decorative ceramic composite board with sound-absorbing function. Its structure mainly includes a base layer 1, a sound-absorbing layer 2, and a decorative layer 3. The sound-absorbing layer 2 is adhered to the surface of the base layer, and the decorative layer 3 is arranged on The surface of the sound-absorbing layer 2 described above.

[0024] Wherein, the sound-absorbing layer 2 is provided with honeycomb sound-absorbing holes 20, and the sound-absorbing holes 20 are regular polygons. In this embodiment, the sound-absorbing holes 20 may be regular hexagons, regular octagons, or regular decagons.

[0025] A number of long grooves 201 are provided in each sound-absorbing hole 20, and the long grooves 201 are equally spaced in the regular polygon.

[0026] The two free ends of the long groove 201 are both arc-shaped, and each of the long grooves 201 is provided with two symmetrical sound insulation p...

Abstract

The invention discloses a decorative ceramic composite board having sound absorption function, which includes a base layer, a sound absorption layer and a decorative layer. The sound absorption layer is provided with honeycomb-like sound absorption holes. A plurality of long slots are disposed in each sound absorption hole. Two free ends of each long slot are both arc-shaped. Two symmetrical sound insulation parts are arranged in each long slot and are protruded from the bottom surface of the sound absorption hole. The two sound insulation parts divides the long slot into three parts: a first sound absorption slot hole, a second sound absorption slot hole and a third sound absorption slot hole, wherein the second sound absorption slot hole is located between the first and the third sound absorption slot holes and the first and the third sound absorption slot holes are located symmetrically relative to the second sound absorption slot hole. One side of each of the two sound insulation parts is inclined surface. The two inclined surfaces are respectively closed to the first and the second sound absorption slot holes. The sound absorption structure can attenuate sound sources in low-frequency band and high-frequency band, so that the board has good environmental noise reducing function.

Description

technical field [0001] The invention relates to the field of ceramic building materials, in particular to a decorative ceramic composite board with a sound-absorbing function. Background technique [0002] With the rapid development of the construction industry, various functional building materials have also developed. At present, building thermal insulation materials are mainly foamed ceramics. Most of the foamed ceramic boards use expensive ore and fine ceramics as the main materials, which have high production costs and consume a lot of resources. Foamed ceramic insulation boards are not widely used Applications. In addition, ordinary thermal insulation ceramic plates have poor sound absorption performance, which restricts the development of foamed ceramics. Contents of the invention [0003] The purpose of the present invention is to overcome the above problems in the prior art, and provide a ceramic composite board, which can achieve better sound-absorbing effect i...
