Abstract
The utility model discloses a sound insulation aluminum alloy composite sheet belongs to the building material field, and aim at solves the current sound insulation board poor problem of sound insulation effect. The sound insulation aluminum alloy composite board is simple in structure, the polycarbonate board is used as the center, and the sound absorption cotton layer, the aluminum alloy thin plate and the outer layer film are sequentially arranged on the two sides of the sound insulation aluminum alloy composite board. The outer membrane is the polyvinyl chloride membrane, inhale the cotton layer of sound and be artificial inorganic fiber thin layer, the polycarbonate board is triangle transparent construction board, adopt the hot melt adhesive to bond between aluminum alloy sheet metal, soundproof cotton layer and the polycarbonate construction board. The utility model discloses an aluminum alloy plate that light, intensity are good, corrosion resistance is strong for avoiding long-term contact air to lead to appearing corrosion, adopts the polyvinyl chloride membrane to carry out further protection to its surface, meanwhile, inhales the propagation of absorption, noise reflex that cotton layer and polycarbonate board can be further, the enhancement composite sheet that can be further give sound insulation effect to the noise.
Description
Technical Field
The utility model relates to a building material field, concretely relates to heat and sound insulation aluminum alloy composite sheet.
Background
Noise is a type of sound that causes irritation or is too loud and harmful to human health. Noise is from many sources, such as plant equipment operation, street automobiles, construction site machinery sounds, and the like, affecting people's daily lives. It is therefore necessary to install or construct an area having a soundproof effect at the roadside, in an area where staff and workers gather.
At present, the acoustic celotex board mainly adopts materials such as comparatively closely knit steel sheet, timber to make, inhales sound, syllable-dividing effect is limited, thereby simultaneously because expose in the air for a long time, also can cause the acoustic celotex board to appear corroding influence life. Aluminum alloy plates have also been used to make acoustical panels because of their light weight, good strength, high corrosion resistance, and good workability, however, the use of simple aluminum alloy plates alone does not meet the acoustical requirements.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art, the utility model provides a simple structure, inhale sound and give sound insulation effectual aluminum alloy composite panel.
The utility model discloses the technological effect that will reach is realized through following scheme:
the sound insulation aluminum alloy composite plate comprises an outer layer film, an aluminum alloy sheet, a polycarbonate structural plate and a sound insulation cotton layer, wherein the composite plate is composed of the outer layer film, the aluminum alloy sheet, the sound insulation cotton layer, the polycarbonate structural plate, the sound insulation cotton layer, the aluminum alloy sheet and the outer layer film.
Preferably, the outer layer film is a transparent ultraviolet-proof film, is made of polyvinyl chloride and has a thickness of 0.4-0.5 mm.
Preferably, the aluminum alloy sheet is AA6061 type, and the thickness of the aluminum alloy sheet is 3-4 mm.
Preferably, the soundproof cotton layer is an artificial inorganic fiber having a thickness of 2 to 3 mm.
Further, the polycarbonate structural plate is a triangular transparent polycarbonate structural plate, and the thickness of the polycarbonate structural plate is 3-4 mm.
Furthermore, the aluminum alloy thin plate, the soundproof cotton layer and the polycarbonate structural plate are bonded by hot melt adhesive.
The utility model discloses an aluminum alloy sheet metal that light, intensity are good, corrosion resistance is strong for avoiding long-term contact air to lead to appearing corrosion, adopts the polyvinyl chloride membrane to carry out further protection to its surface. Meanwhile, the sound absorption cotton layer and the polycarbonate plate can further absorb and reflect noise, and the sound insulation effect of the composite plate on the noise can be further enhanced.
Advantageous effects
① the aluminum alloy sound insulation composite board has simple structure, smart design, portability and easy installation;
② this aluminum alloy composite sheet that gives sound insulation adopts the aluminum alloy sheet metal, inhales the transmission that cotton layer and polycarbonate board can effectual noise reduction as sound insulation material, isolated noise.
