Embodiment Construction

[0015] Below in conjunction with accompanying drawing, invention is described in further detail.

[0016] Such as figure 1 As shown, a sandy sound-absorbing panel is mainly composed of at least two sound-absorbing material bodies 1 that are combined and integrally formed. The sound-absorbing material body 1 is formed by pressing natural round quartz sand 11 and resin glue after mixing. Adhesive covering layers 12 coated on the surfaces of the two sound-absorbing bodies are arranged between the two sound-absorbing bodies. The integrally formed sound-absorbing material passes through the resin glue and the adhesive covering layer 12, and the gaps between the natural round-grained quartz sand 11 particles form sound-absorbing pores. Resin glue is a polymer synthetic resin. It is a kind of hydrocarbon whose main chain does not contain unsaturated structure synthesized by various resin materials. It can be used to make acrylate coatings, or it can be polymer resins such as epoxy ...

Abstract

The invention discloses a sandy sound absorbing plate and a preparation method thereof. The plate is mainly composed of at least two sound absorbing material bodies integrally formed; the sound absorbing material bodies are made from natural round grain quartz sand and resin glue through mixing and pressing; the two sound absorbing material bodies are provided with an adhesive covering layer respectively applied on the surfaces of the two sound absorbing material bodies; after the integrally formed sound absorbing material bodies are covered with the resin glue and the adhesive covering layer,sound absorbing holes are formed in gaps among the natural round grain quartz sand particles. The method has the advantage of obtaining a better sound absorbing effect.

Description

technical field [0001] The invention belongs to sound-absorbing materials for buildings, in particular to a floor, wall and surface widely used in concert halls, theaters, recording rooms, studios, conference rooms, gymnasiums, exhibition halls, dance halls, KTV rooms and other public places. Sandy sound-absorbing panels in ceilings and methods for their preparation. Background technique [0002] Sound originates from the vibration of an object, which causes the vibration of the adjacent air to form sound waves, and propagates around in the air medium. When the sound is transmitted to the surface of the component material, part of the sound energy is reflected, part of the sound energy penetrates the material, and part of the sound energy is converted into heat energy due to the vibration of the component material or the friction with the surrounding medium when the sound propagates in it, and the sound energy is lost. . Therefore, most sound-absorbing materials are loose ...
