A kind of decorative fireproof sound-absorbing board and preparation method thereof

Abstract

The invention discloses a decorative fireproof acoustic absorption board which comprises a fireproof acoustic absorption assembly and a decorative layer. The fireproof acoustic absorption assembly comprises an acoustic absorption layer and fireproof layers oppositely arranged on the two sides of the acoustic absorption layer. The fireproof layers are made of cement-based acoustic absorption boards. Each fireproof layer is provided with a sediment tank. The bottom of each sediment tank is provided with multiple discontinuous conical protrusions. Each protrusion is provided with a supporting arc portion. The acoustic absorption layer is arranged among the supporting arc portions inside the fireproof layers. The decorative layer is arranged on the surface of the fireproof acoustic absorption assembly. The decorative fireproof acoustic absorption board can achieve the A-level fireproof function, and can have the better acoustic absorption effect, lower quality and better stability due to the unique structural design. The invention further provides a preparation method of the decorative fireproof acoustic absorption board. Due to the fact that the formula is simple and the preparation method is simple, the decorative fireproof acoustic absorption board has the strong physical structure stability, good foaming effect and lower quality.

Description

technical field [0001] The invention relates to a decorative panel for use in the case of wall decoration. More specifically, the present invention relates to a decorative fire-proof sound-absorbing panel used in the case of wall decoration and a preparation method. Background technique [0002] Specifically, usually decorative fireproof sound-absorbing panels include the following structures: decorative layer and fireproof sound-absorbing, [0003] The fire-proof and sound-absorbing layers in the prior art are mostly made of A-grade cement foam boards with flame-retardant effect as heat preservation, fire prevention and sound-absorbing materials. However, although the existing cement foam boards have excellent fireproof properties, they all have high water absorption and poor antifreeze performance. In winter, especially in the north, they are prone to cracking, and rainwater is easily sucked into the board. The thermal conductivity of the material increases after absorbin...

AI Technical Summary

Problems solved by technology

However, although the existing cement foam boards have excellent fireproof properties, they all have high water absorption and poor antifreeze performance. In winter, especially in the north, they are prone to cracking, and rainwater is easily sucked into the board. The thermal conductivity of the material increases after absorbing water. , leading to a decrease in thermal insulation performance and an increase in bulk density, which is prone to safety accidents such as separation from the wall and falling from high altitudes; in addition, although its fire resistance performance is A-level, its sound absorption effect is not good, and its quality is heavy, which cannot meet modern decoration requirements.

[0004] The existing decorative fireproof sound-absorbing panels use keels to install on the installation surface, but the installation is troublesome and the stability is not enough, especially in the outdoors, it is very easy to fall off, and the safety factor is low

[0005] In addition, the cement foam board in the current decorative fireproof sound-absorbing board is backward in preparation level and formula, so the structural stability of the prepared cement foam board is not enough, and the foaming degree does not meet the requirements
