Abstract
The utility model provides a decorative sound absorbing ceiling board, comprising a flame-proof decorative panel and a flame-proof sound absorbing material layer. The layered structure is that an outer layer is the flame-proof decorative panel, and an inner layer is the flame-proof sound absorbing material layer. The decorative panel is provided with an opening, the area of the opening occupies 5-60% of the total area of the decorative panel, and the diameter of the opening is 0.1-1.5 mm. The high-efficient sound absorbing ceiling board of the utility model is formed by two portions, the decorative panel and the sound absorbing material which are made according to certain technical requirement. The decorative sound absorbing ceiling board has good ornamental function, water proof, corrosion proof, moth proof, flame proof, easy maintenance and repair, convenient mount and repair, superior quality, moderate price, green environment protecting, no breaking for human body health, fire proof, security, stable and reliable sound absorptive performance for a long time, wide sound absorption band and obvious middle and low frequency sound absorption effect.
Description
Technical field:
The utility model relates to a kind of decoration acoustical ceiling of standard, belongs to International Classification of Patents E04B1/86 " board-like Sound-absorbing member " technical field.
Background technology:
Ceiling has used for many years, still, both at home and abroad also without any a kind of decoration acoustical ceiling that possesses the standard sound absorption function, causes blank to this area at present, also makes the noise problem such as office and public place be difficult to be resolved
Summary of the invention:
The purpose of this utility model provides a kind of beautifying and decorating effect that both had, decoration acoustical ceiling that again can absorption of noise.
The utility model by the following technical solutions.
A kind of decoration acoustical ceiling is made of flame-retardant decorative panel (1), fire-retardant sound-absorbing material layer (2), and its hierarchical structure: skin is flame-retardant decorative panel (1), and nexine is fire-retardant sound-absorbing material layer (2).
Decoration panel (1) is provided with perforate, and the area of its perforate accounts for the 5-60% of the decoration panel gross area, and opening diameter is 0.1-1.5mm.
Decoration panel (1) is made by materials such as aluminium alloys, wood strip plate, color steel, mineral wool, composite materials.
The sound absorption flow resistance of sound-absorbing material layer (2) is 40-150 Newton-second rice m
2, handkerchief rice second m
2Between.
Sound-absorbing material layer is selected from materials such as organic-inorganic fiber, plastic foam, polyurethane foam, glass fiber, glass wool, glass fiber, mineral wool, sponge.
Decoration acoustical ceiling of the present utility model is the decoration panel of being made according to certain technical requirements by multiple material, and the combination of fire-retardant sound absorption material two parts, and the efficient decoration acoustical ceiling of making.Keep good decorative property, waterproof, corrosion resistant is mothproof, and is fire-retardant, is easy to maintenance, and installation and maintenance are convenient, and quality is excellent, moderate cost, environmental protection is to the health not damaged.Have plurality of advantages such as the feature of environmental protection, functional, safety (fire prevention), ornamental and economy.Be the acoustic construction design according to science, it is controlled to have the sound absorption material performance, the sound absorbing capabilities long-term stability, and acoustic frequency bandwidth, especially the medium and low frequency acoustically effective is obvious.Satisfying with this having sound absorption to require and noise control in modern architecture.Extensive market, less investment, instant effect, economy and society remarkable benefit.
Description of drawings:
Fig. 1 is the structural representation of the utility model combined ornamental sound absorption screen.
Among the figure: 1, decoration panel, 2, fire-retardant sound-absorbing material layer.
The specific embodiment:
The utility model provides a kind of combined ornamental acoustical ceiling, is made of decoration panel (1), sound-absorbing material layer (2), and skin is flame-retardant decorative panel (1), and nexine is fire-retardant sound-absorbing material layer (2).
