Colored pottery sand acoustic board and preparation method thereof

Abstract

The invention discloses a colored pottery sand acoustic board which comprises a nano fine sand layer, a fine sand layer and a ceramsite layer, reinforced glass fiber gridding cloth is arranged on the ceramsite layer, the fine sand layer is arranged on the reinforced glass fiber gridding cloth, and a nano fine sand layer is arranged on the fine sand layer. Different decoration effects can be achieved by adopting different methods for surface layer treatment, and the surface layer treatment is determined according to user requirements and can be freely changed. The invention can enrich the market diversification of building sound absorption materials at home and abroad, improve the quality, market occupancy and utilization rate of the building sound absorption materials and meet the requirements of modern living standard of people, and provides a novel updating product which can be directly attached to a wall for installation, has a better sound absorption effect without a cavity, achieves A1-level fire prevention and adopts a sintering principle of a processing flow. The invention has the characteristics of no pollution, moisture resistance, collision resistance, zero emission of harmful gas, no secondary pollution, good surface layer effect and the like.

Description

technical field [0001] The invention relates to an environment-friendly sound-absorbing board, in particular to an environment-friendly sound-absorbing board made of a mixture of painted ceramsite and sandstone and a preparation method thereof. Background technique [0002] Sound-absorbing materials are functional materials for architectural decoration. Through the absorption of noise by materials, reasonable sound quality design provides people with a quiet and comfortable living environment and place. There are many types of sound-absorbing materials for architectural decoration in the domestic market. Each has advantages and disadvantages, such as poor fire protection rating, not wide absorption frequency band, fear of collision after decoration, poor overall surface effect, secondary pollution and other undesirable phenomena, it is difficult to meet the needs of modern building development. Contents of the invention [0003] The object of the present invention is to pr...
