[0002] The ceiling is one of the sound-absorbing materials, and it is also an important means of sound absorption and noise reduction in architectural decoration and architectural acoustic design. There are many types of architectural sound-absorbing ceilings on the existing market. Ordinary ceilings are mainly made of rock wool boards, mineral wool boards, Glass wool board is the main type, and there are also perforated composite sound-absorbing ceilings. These sound-absorbing ceilings have their own advantages and disadvantages. There are not many materials with good comprehensive performance, and it is difficult to meet the needs of modern building development. Multifunctional sandstone microbeads are environmentally friendly and sound-absorbing The ceiling overcomes the disadvantages of the existing market building sound-absorbing materials, and achieves convenient material selection, controllable sound-absorbing performance, adjustable frequency, high sound-absorbing coefficient, A-level fire protection, no harmful gas release, no fear of humidity, strong weather resistance, Comprehensive and excellent sound-absorbing ceiling without secondary pollution

Embodiment Construction
[0009] The sandstone microbead environmental sound-absorbing ceiling is composed of four parts: a base layer (1), a skeleton layer (2), a hollow glass bead layer (3) and a decorative effect layer (4).
[0010] Step 1: Select round sand grains or hollow glass microspheres or closed-cell perlite with the same particle size, and use epoxy resin or polyurethane adhesive; Step 2: After mixing, put them in a standard mold for compaction ;The third step: Cut the grid cloth or glass fiber thin mat into specifications and place it on the base layer; After the parts are evaporated, each layer can stick together, and different pores appear in each layer, which play the role of sound absorption; the fifth step: after dragging the mold, use natural white sand and adhesive to mix or paint or paint for surface treatment , The opening rate of the surface layer is between 15% and 60%, and different pore decorative effect layers are used when absorbing different frequencies.

Abstract
The invention is a new type of sandstone microbead environment-friendly sound-absorbing ceiling, which belongs to building decoration and sound-absorbing material. , on the base layer, there is a skeleton layer of grid cloth or glass fiber felt, on the skeleton layer, a hollow glass bead layer, on the hollow glass bead layer, a decorative effect layer, the first three layers are pressed tightly on the mold In the middle, after the moisture evaporates and the adhesive is solidified, natural pores will appear in the board to play a role in sound absorption, and then the natural white sand particles are mixed with the adhesive or the decorative effect layer is treated with paint or paint. The surface layer has a porosity of 15%‑60%, beautiful and elegant, but also has sound absorption effect. The specific flow resistance of each layer is 800Pa s / m‑1800Pa s / m. Different frequency sound absorption needs use different particle sizes to ensure high and high Low frequencies have prominent absorption.
