Problems solved by technology

[0003] If a material layer such as concrete with a heavy weight is laid on it, the above-mentioned sponge or rubber sheet is easily deformed due to the influence of its material, making the surface of the building uneven, cracks appear, and the sponge or rubber layer becomes thicker.
[0004] Moreover, even if the existing technology can shield the noise and vibration generated between the building layers, it cannot shield the electromagnetic waves and water pulse waves that are increasingly valued in modern social life.

Embodiment 1

[0047] The above-mentioned conductive layer 20 is coated on the surface of the upper plate, and the coating method is carbon coating or adding carbon to the synthetic resin material and then thermocompression bonding to form a carbon coating film.

[0048] Then measure the surface resistance of the upper plate portion 12, and its surface resistance reaches 103~1011Ω / cm 2 , Effectively improve the anti-static effect.

Embodiment 2

[0050] When using any one of nickel, copper, silver, potassium, magnesium, cadmium and aluminum to make the sheet-shaped conductive layer 20 and apply it on the shelf, its surface resistance can reach 103~108Ω / cm 2 , not only has the antistatic effect, but also has the following electromagnetic wave shielding effect.

[0051] When testing the shielding effect of the upper plate portion 12 on electromagnetic waves, the test method of “ASTM D4935-89” is used for measurement, and the decibel value (A) is 8±05dB. Substituting the above-mentioned decibel value (A) into the calculation formula of electromagnetic wave shielding effect (shielding effect (%)=(1-10-A / 10)×100%) is calculated, and 82.21% to 85.87% of electromagnetic waves can be shielded.

Embodiment 3

[0053] Use any metal powder 20-30% (weight) of nickel, copper, silver, potassium, magnesium, cadmium and aluminum to mix with 70-80% (weight) carbon powder to make the above-mentioned conductive layer in sheet form 20 and apply to the top of laminate flooring. As a result of the above coating, the surface resistance reaches 103~109Ω / cm 2 , Effectively improve the anti-static effect.

[0054] As a result of measuring electromagnetic waves using the "ASTM D4935-89" test method of Example 2, 60 to 65% of electromagnetic waves can be shielded.

[0055] Furthermore, it was confirmed that the present invention can shield water pulse waves, which are increasingly important in modern social life. The water pulse wave is a harmful wave that is generated when it rushes to the surface from a depth of 100~200m or more underground, and the harmful wave can be neutralized and rendered ineffective by causing a beneficial wave in the place where the harmful wave exists. At present, countries...

Abstract

The invention relates to a sound-insulating material that can prevent noise between floors and buildings and a noise-proof process based on the above-mentioned sound-insulating material. Static electricity, electromagnetic waves and water pulse waves. The soundproof material (10) of the present invention comprises an upper plate portion (12); a support portion (14) supporting the upper plate portion (12); and a filling unit (15) filled between the support portions (14). A noise-proof device (16) made of rubber is installed below the above-mentioned support portion (14). The present invention has at least the following effects. First, it can effectively prevent the noise or moisture generated between the floor and the building layers; second, it can prevent the deformation of the sound insulation material when it expands and contracts with temperature changes; third, it can shield the building layers Generated static electricity and water pulse waves.

Description

technical field [0001] The invention relates to a sound-insulating material that can prevent noise between floors and buildings and a noise-proof process based on the above-mentioned sound-insulating material. Static electricity, electromagnetic waves and water pulse waves. Background technique [0002] In order to shield the floor and the noise generated between the building layers, the prior art generally installs a sound-absorbing sponge or rubber sheet (Mat) between the building layers. [0003] If when laying heavy concrete and other material layers above, the above-mentioned sponge or rubber plate will easily cause deformation due to the influence of its material, so that the building surface will be uneven, cracks will appear, and the sponge or rubber layer will become thicker. [0004] Moreover, even if the existing technology can shield the noise and vibration generated between the building layers, it cannot shield the electromagnetic waves and water pulse waves th...
