[0050] A method for preparing the above-mentioned impact-resistant sound-absorbing panel, comprising the steps of:

[0051] (1) The first mixture is obtained by mixing an adhesive with a mass percentage of 2%-10% and a particle with a mass percentage of 90%-98%, wherein the adhesive includes a resin mixture, and the particle includes aeolian sand. In order to prepare the sound-absorbing layer.

[0052] Optionally, the adhesive includes a resin mixture, graphene material and silane, first mix the resin mixture, graphene material and silane to obtain a 2%-10% adhesive, and then mix it with the particles to obtain the second a mixture. Divided into two mixing, the mixing of the adhesive and the first mixture is more uniform, especially the graphene material is added to the adhesive, the bonding performance between the adhesive and the particles is better, and the final impact resistance The impact resistance of the sound-absorbing panel is stronger.

Abstract

The invention provides an anti-impact sound absorption material composition, an anti-impact sound absorption board and a preparation method thereof and belongs to the technical field of sound and noise reduction materials. The anti-impact sound absorption material composition is prepared from the following components in percentage by mass: 2 percent to 10 percent of an adhesive and 90 percent to 98 percent of particulate matters; the adhesive comprises resin mixed liquid; the particulate matters comprise aeolian sand. The anti-impact sound absorption board comprises a sound absorption layer and a supporting layer; the sound absorption layer is arranged at one side of the supporting plate; the sound absorption layer is prepared from the anti-impact sound absorption material composition. Theanti-impact sound absorption board prepared from the anti-impact sound absorption material composition has relatively good sound absorption performance and anti-impact performance.

Description

technical field [0001] The invention relates to the technical field of sound-absorbing and noise-reducing materials, in particular to an impact-resistant and sound-absorbing material composition, an impact-resistant and sound-absorbing panel and a preparation method thereof. Background technique [0002] Traditionally used sound-absorbing materials are generally fiber-based porous sound-absorbing materials, such as mineral wool, rock wool, centrifugal glass wool, etc. Such fiber-based sound-absorbing materials have problems such as environmental pollution in the production, use, and recycling links; in addition, in In the process of use, the sound-absorbing material will sink due to moisture and pulverization of the fiber, which will reduce the acoustic performance; and the fiber-based sound-absorbing material needs to have a protective layer during use, and the decorative performance is poor. [0003] For this reason, many new environmentally friendly sound-absorbing materi...
