Problems solved by technology

[0009] Third, anti-static tiles that are pressure-formed after coating on the particles of synthetic resin parts cannot avoid discontinuous sections of carbon, so static electricity will occur locally
[0010] Fourth, it is necessary to increase the coating process and other operations for synthetic resin particles, which complicates the process and increases production costs
[0012] However, the above-mentioned patents are difficult to reduce the surface resistance to 10 9 Ω / cm 2 Below, and even if the surface resistance is reduced, the volume resistance is maintained at 10 because the volume resistance cannot be reduced. 14 Ω / cm 2 , so that the above-mentioned anti-static tiles have properties similar to non-conductors as a whole and cannot effectively exert the anti-static effect
[0013] In order to solve the above problems, although the surfactant can be mixed into the tile body to reduce the surface resistance and volume resistance, the bleeding phenomenon of the surfactant pollutes the surface of the tile and makes each layer peel off.

Embodiment 1

[0049] Embodiment 1 (surface resistance of ceramic tile of the present invention)

[0050] Coat carbon on the conductive unit (40) positioned at the lower surface of the above-mentioned lower layer, add 5% (volume ratio) surfactant in the lower layer, insert its upper and lower sides between the upper layer (10) and the lower layer (20) and coat Aluminum sheet (52) made of polyethylene, and the results of evaluating the resistance between electrodes on the same plane showed that its surface resistance was 10 8 Ω / cm 2 And it is lower than the existing antistatic ceramic tile (100), which not only contributes to the antistatic effect, but also can exert the electromagnetic wave shielding effect as shown below.

Embodiment 2

[0051] Embodiment 2 (volume resistance of ceramic tile of the present invention)

[0052] In the invention of the above-mentioned embodiment 1, the resistance value is measured after the electrodes are arranged along the thickness direction, and it can be known that when the volume resistance is arranged along the thickness direction, the volume resistance value is 10 8 Ω / cm 2 .

[0053] Therefore, the volume resistance on the embodiment of the present invention is changed from 10 14 Ω / cm 2 down to 10 8 Ω / cm 2 When the overall conductivity of the tile is highlighted, it can effectively reduce static electricity.

Embodiment 3

[0054] Embodiment 3 (electromagnetic wave shielding experiment of ceramic tile of the present invention)

[0055] When testing the electromagnetic wave shielding ability of the antistatic ceramic tile of the present invention, use the "ASTM D4935-89" test method to measure, and its decibel value (A) is 8 ± 05dB.

[0056] Therefore, the above-mentioned test method (A) is substituted into the calculation formula of the electromagnetic wave shielding effect (shielding effect (%)=(1-10 -A / 10 )×100%), it is known that it can shield 82.21%~~85.87% of electromagnetic waves.

Abstract

Disclosed is static electricity proof tile, which has volume resistance lower than conventional tiles, prevents bleeding, which typically occurs in static electricity proof tiles manufactured using a surfactant, blocks electronic waves and water vein waves, and has an excellent moisturization function. The static electricity proof tile (100) according to this invention includes an upper layer (10) and a lower layer (20) provided beneath the upper layer (10) and formed of synthetic resin material containing a surfactant, in which a barrier means (50) is interposed between the upper layer (10) and the lower layer (20) for preventing bleeding of the surfactant. Further, the static electricity proof tile can have volume resistance decreased to 106-1010, compared to conventional static electricity proof tiles, can prevent bleeding of the surfactant contained in the lower layer formed of synthetic resin material and also separation of the tile due to bleeding of the surfactant, and can block electronic waves and water vein waves.

Description

technical field [0001] The invention relates to an antistatic ceramic tile. The volume resistance of the antistatic ceramic tile of the present invention is lower than that of existing ceramic tiles, which can prevent the phenomenon of bleeding (bleeding) of the antistatic ceramic tile based on the surfactant, thereby avoiding the phenomenon of bleeding of the surfactant The peeling phenomenon that makes each layer peel off can shield electromagnetic waves and water pulse waves, and can also exert an excellent moisturizing function. [0002] The anti-static ceramic tile of the present invention is mainly used in the following places and can effectively absorb static electricity or guide it to other places: the floor of the production and assembly lines of semiconductors and other electrical and electronic products; the floor of laboratories, clean rooms and hospital operating rooms, etc. The floor; the floor of the office where harmful electromagnetic waves need to be shielded...
