Description

Artificial mineral fibers sound and heat insulating panel

The present invention relates to a sound insulation and insulation panel using inorganic materials, and to an inorganic sound insulation and insulation panel in accordance with the demand for the reduction of noise between floors and the strengthening of heat insulation regulations in terms of the enhancement of housing and the efficient utilization of energy.

Conventional abatement panels may be placed on the slab by using recycled tire chips and rubber foam panels, and then subjected to finishing mortar on the slab. However, such construction may reduce floor noise, but may require insulation regulations. It does not reach 0.7 ~ 1.0 ㎉ / ㎡.h. ℃, which is the standard of interlayer heat exchange rate, and it does not have enough reducing effect on weight impact sound.

20 mm thick foam polystyrene is laid on the floor slab and fixed with cement nails, concrete is cast 60 mm thick, and a lot of manpower is incurred. There is a problem that the sound is transmitted to the lower floor and surrounding generation without reducing the sound.

Recently, lightweight foam boards and recycled rubber chip insulation buffers are used, but since they are organic products, they shrink and harden during long-term use for 10 to 20 years, resulting in lower sound insulation and insulation performance. Breaking apart occurs.

There are cases of foreign materials using inorganic materials for interlayer reduction materials, but there are cases in which inorganic materials are laid on slabs and moisture-proof films or asphalt roofing are laid on them. Material defects caused by the injury of the starting material may occur, which does not reach the desired function.

The present invention is to wrap the artificial mineral fiber sound insulation and thermal insulation panel wrapped with a polyethylene film on the outside to shorten the complex process as described above, and to facilitate mass supply and simplicity of the process.

As a result, it is possible to achieve the advantages and effects of constructing a structure suitable for insulation regulations and the purpose of reducing interlayer noise.

It is an object of the present invention to provide an inorganic interlayer sound insulation and insulation panel that solves the above disadvantages and provides a thermal insulation effect that has never been before.

The inorganic sound insulation and heat insulation panel of the present invention is manufactured by wrapping the outside of the inorganic plate with a polyethylene film, and the upper surface of the film is formed with two edge wings remaining to cover the inorganic plate so that another pad adjacent to one pad has a wing portion. It is configured to be bonded and bonded.

The construction method of the inorganic sound insulation and insulation panel of the present invention first cleans the bottom impurities and sludge, apply adhesive to the sound insulation and insulation panel, attaches to the wall and the slab bottom, and then taps the wings of the sound insulation and insulation panel It prevents the slurry from penetrating the process, and after curing lightweight foam concrete on the sound insulation and insulation panels, it is cured, and then heating pipes and protective mortar.

The present invention will be described in detail with reference to the accompanying drawings.

In the present invention, the inorganic material is artificial mineral fiber, generally referred to as mineral wool (Mineral Wool) and glass wool (Glass Wool).

Mineral wool is prepared by putting solid slag and andesite into the cupola with coke as fuel and dissolving it at about 1800 ° C. to make it into a liquid state, fiberizing it in a spinner rotating at high speed, and spraying a binder and collecting it with a collector.

Glass wool is manufactured using crushed glass, silica sand, feldspar, dolomite, limestone, soda ash, and borax.

Glass wool and mineral wool have less dynamic stiffness than other materials, but the dynamic stiffness increases with density and decreases with increasing thickness. Generally, the smaller the dynamic stiffness, the greater the effect of reducing impact sound. When used as a cushion of the floating floor structure, it is advantageous for the floor impact sound performance.

The damping coefficient of the glass wool or mineral wool is about 20 to 30%, and the conventional styropol and the existing buffer have a damping coefficient of about 15%.
