Novel micropore aluminum foil sound absorption acoustic screen

Abstract

The invention discloses a novel micropore aluminum foil sound absorption acoustic screen and relates to the technical field of building material decoration products. By adopting the key technology of 'using ultra-thin aluminum foil as a substrate micropore sound absorption structure', the manufacturing method comprises the following steps: the substrate aluminum foil is subjected to cutting, shearing, pricking, swaging, gluing, bonding and sawing to be manufactured into micropore sound absorption aluminum foil for use; an aluminum plate is subjected to cutting, scribing, angle opening, punching, bending, welding, polishing and spraying to be manufactured into an acoustic screen body for use; the micropore sound absorption aluminum foil and the acoustic screen body are assembled together to be manufactured into the finished product of the novel micropore aluminum foil sound absorption acoustic screen. The novel micropore aluminum foil sound absorption acoustic screen is used for sound absorption and insulation, and is ingenious in conception, reasonable in structure, good in sound absorption and insulation effect, resistant to impact, safe, reliable, retardant to flames, durable, convenient to install, use and maintain, attractive and elegant as a whole, easy to manufacture, low in cost, wide in application range, and beneficial to popularization and application.

Description

technical field [0001] The novel microporous aluminum foil sound-absorbing and sound-insulating screen of the invention relates to the technical field of building material decoration products; in particular, it relates to the technical field of sound-absorbing and sound-insulating building material decoration products. Background technique [0002] At present, sound-absorbing and sound-insulating screens are mainly used in traffic and municipal facilities such as expressways, elevated composite roads, and urban light rail subways for sound insulation and noise reduction and traffic noise control to solve the impact on nearby urban areas, and can also be used for factories and other noise sources. sound insulation and noise reduction. In terms of road sound-absorbing barriers, the traditionally designed sound barriers are divided into pure sound insulation reflective sound barriers and composite sound barriers that combine sound absorption and sound insulation. The latter is ...

AI Technical Summary

Problems solved by technology

At present, the sound-absorbing materials selected for the core layer of most sound barriers are: polyester fiber sound-absorbing panels, groove wood sound-absorbing panels, hole wood sound-absorbing panels, regenerated wood sound-absorbing panels, quartz cotton sound-absorbing panels, high-temperature ceramic sound-absorbing panels, and foamed aluminum sound-absorbing panels. Among them, polyester fiber sound-absorbing panels, grooved wood sound-absorbing panels, hole wood sound-absorbing panels, and regenerated wood sound-absorbing panels cannot be used outdoors because they cannot withstand rain and soaking, and can only be used for interior decoration; quartz wool sound-absorbing panels contain rock wool The ingredients can make people sick. Although the sound-absorbing effect of quartz wool is good, it must be used together with polyester fiber sound-absorbing panels, but the service life is limited under rainwater infiltration; when quartz wool and polyester fiber are used together, they are not transparent. Yes, when there is a strong wind, there will be a lot of wind pressure, and the amount of steel used for the support frame must be increased, and the cost of use is very high.
