Foam Aluminum Sound Absorbing Panel for Ceiling

(Technology)

The present invention relates to a foamed aluminum sound-absorbing panel for ceiling, and more particularly, to form a variety of decorative yin embossed on the foamed aluminum surface with open air bubbles, as well as function as a finishing material by construction on the ceiling of the building The present invention relates to a ceiling finishing sound absorbing panel having sound absorption and sound processing functions.

(Background)

In everyday life, undesired sound, ie noise, is generated by various factors such as the operation of various mechanical equipment, the operation of transportation means such as automobiles, railways, subways, aircrafts, the construction of heavy equipment, or the operation of various acoustic devices. It is ready. These noises personally cause hearing loss, headaches, anxiety, etc., and cause harm to health, and in an industrial site, create a poor working environment and generate vibrations, resulting in deterioration of productivity and product quality.

Therefore, the noise sources should be designed to generate as little noise as possible, and if the noise is inevitably generated, measures should be taken to prevent the noise from propagating outside.

The need for sound insulation is almost all around, such as workplaces, roadsides, railroads, airports, construction sites, heavy equipment, communal dwellings such as apartments or offices, concert halls or theaters, indoor sports facilities, and various recreational facilities. It is required for living environment.

As a conventional soundproofing method, various soundproofing materials made of a material having sound absorption or soundproofing performance are used, and soundproof structures such as soundproof walls, partitions, soundproof rooms, and finishing materials for sound treatment are absorbed and propagated. Blocking paths is widely used.

In general, the soundproofing materials widely used include various materials such as general building materials such as wood or concrete, synthetic resin materials such as polyurethane, polyethylene or polyester, inorganic fiber materials such as glass wool or rock wool, and metal materials such as metal perforated plates. And single or combination thereof.

The sound insulation material may vary depending on the place and purpose of use, but it has excellent sound absorption and sound insulation in a wide frequency range, excellent mechanical properties (durability, etc.), and thermal properties (non-flammability, flame retardancy, etc.), but the manufacturing cost is low and construction is easy. It would be desirable to be simple and harmless to the human body.

However, conventional sound insulation materials do not meet the requirements of some of the various requirements described above, and present significant problems in applying them to the construction of sound insulation facilities. For example, soundproofing materials made of wood or plastic resin are weak to heat and vulnerable to fire. Glass wool and rock wool have a problem of causing environmental pollution, and aluminum plates are not sufficiently capable of preventing noise. There is a limit. In addition, conventional soundproofing materials other than metal materials are almost impossible to recycle, generating a lot of garbage.

Particularly, in the sound absorbing panels for ceilings constructed on the ceiling of buildings, materials such as rock wool, asbestos, glass wool, perforated tex, gypsum board, and hard boards are mainly used, and these conventional ceiling sound absorbing panels cannot be recycled. In addition to the problems of acting as a cause of controversy and environmental pollution as well as carcinogens, it is not suitable for use as a finishing material due to its weak strength or heavy weight, and it is not suitable for use as a finishing material. There is a problem.

The object of the present invention is excellent in sound absorption performance, harmless to the human body, does not cause pollution, and can be recycled, light weight and robust, easy to install, and can be easily processed to have a beautiful appearance, and also serves as a finishing material It is to provide an ultra-light weight non-combustible sound absorbing panel that can be used.

The object of the present invention described above is to form a variety of decorative embossed on the surface of the foamed aluminum panel having an open air bubble to selectively use the coating material to be used as a finishing material having sound absorption performance, non-combustible, lightweight ceiling Is achieved by foamed aluminum sound-absorbing panels.

More specifically, an object of the present invention is based on a foamed aluminum panel having an open bubble prepared by rolling a foamed foamed aluminum foam to convert a closed bubble into an open bubble, and having the open bubble It is achieved by a ceiling foamed aluminum sound absorbing panel formed by forming various patterns on the surface of the foamed aluminum panel, the surface of the patterned panel can be painted to further highlight the function as a finishing material.

The foamed aluminum panel having a plurality of open bubbles used as a base material for the ceiling foamed aluminum sound absorbing panel according to the present invention is formed by foaming aluminum to form a plurality of open bubbles. In the foamed aluminum panel having open bubbles, aluminum metal is melted in a mold equipped with a heater and a stirrer, a viscosity increasing agent is added to maintain a proper viscosity, and then a foaming agent is added to form bubbles. After producing foamed aluminum by a known aluminum foaming process, the foamed aluminum is rolled to produce a method of converting closed bubbles into open bubbles.

Here, the open bubble means that the bubbles formed in the foamed aluminum are open rather than closed. Most of the bubbles of foamed aluminum produced by conventional methods are closed so that each bubble forms a closed space. Since foamed aluminum having bubbles in the closed space does not sufficiently exhibit the effect of the bubbles absorbing sound waves, the foamed aluminum does not exhibit sufficient sound insulation performance for the purpose of the present invention. Accordingly, in the present invention, the foamed aluminum is lightly rolled by a rolling mill to burst the closed bubbles and convert them into open (opened) bubbles.

Rolling foamed aluminum to convert closed bubbles to open bubbles is achieved by, for example, pressing the foamed aluminum panel in the thickness direction to reduce the thickness of the foamed aluminum panel with the closed foam to 20-30%. . Rolling reduction can be appropriately adjusted according to the use, thickness, etc. of the foamed aluminum panel, but it is necessary to prevent the bubbles from being squeezed out by increasing the rolling amount excessively. The foamed aluminum panel thus produced becomes porous including a large number of open bubbles, and at least 90% of the total volume becomes an ultra-light absorption panel made of bubbles.

Hereinafter, with reference to the accompanying drawings will be described in detail a foamed aluminum sound absorbing panel for a ceiling according to the present invention.
