[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 the specified size and put it on the base layer; After the parts are evaporated, each layer can stick together, and each layer has different pores, which play a role in 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 provides a sandstone microbead environment-friendly acoustical ceiling, and belongs to building decoration sound absorption materials. The sandstone microbead environment-friendly acoustical ceiling is composed of four parts, round sand grains or hollow glass microbeads or closed cell perlite and a binding agent are mixed to be pressed to form a base layer, and a gridding cloth or glass fiber mat framework layer is arranged on the base layer. A hollow glass microbead layer is arranged on the framework layer, and a decoration effect layer is arranged on the hollow glass microbead layer. The first three layers are tightly pressed in a mould, after water evaporates, and the binding agent is solidified, natural pores are formed in a plate, and a sound absorption effect is achieved. Then natural white sand grains and the binding agent or coatings or paint are mixed to process the decoration effect layer, and the porosity of a face layer of the decoration effect layer is 15%-60%. While attractiveness and elegance are achieved, the sound absorption effect is also achieved. The specific flow resistance rate is 800 Pa.s / m-180 Pa.s / m after all the layers are put together, different grain diameters are used according to different frequency sound absorption demands, and it is guaranteed that excellent absorption is achieved in high, medium and low frequency.
