Description
CONDUCTIVITY FOAMING SHEET FOR PROTECTING LCD PANEL PROTECTION AND ITS USAGE
Technical Field
[1] The present invention relates to a foam sheet of 0.3 to 2 D thickness used to pack electronic components sensitive to static electricity such as LCD (Liquid Crystal Display) panels, which is, in use, interposed between LCD panels stacked horizontally to absorb shock and prevent static electricity. Background Art
[2] Conventionally, a conductive foam product was manufactured through many processes, for example, for coating a conductive film on both surfaces of a cushioning material or applying a conductive ink to both surfaces of a cushioning material, in the case that a conductive film is coated on both surfaces of a cushioning material, the conductive film is stuck onto the surface of an LCD panel and is not easily removed from the surface of the LCD panel, and in the case that a conductive ink is applied to both surfaces of a cushioning material, carbon falls off by friction during delivery, thereby resulting in partial antistatic characteristics.
[3] And, as disclosed in Korean Patent Laid-open Publication No. 1995-0016469, conventionally, LCD panels are arranged vertically in a transport box having a plurality of grooves formed on inner side walls for holding the LCD panels such that each of the LCD panels is inserted into the grooves, and a conductive film or a separate buffer material is interposed between the LCD panels for antistatic and cushioning performance.
[4] That is, conventionally, because the LCD panels were packed as they were inserted vertically into the grooves, the number of LCD panels arranged in the transport box was limited to increase packing and delivery costs, and the grooves caused a gap, through which air and moisture came into the transfer box, thereby creating an oxidation environment, consequently occurring rust to the LCD panels, and in the case that a film having an antistatic function and a cushioning sheet were used together or a foam product with a cushioning function, not an antistatic function was used, antistatic and cushioning performance were not achieved at the same time.
[5] And, because an interleaving sheet interposed between LCD panels was coated with a film or ink for antistatic performance, in the case that the interleaving sheet was absorbed by vacuum for realization of an automation system, the interleaving sheet was not easily removed from a vacuum absorption nozzle, which makes it difficult to move the interleaving sheet by vacuum pressure, thereby hindering realization of an
automation system, and further, to move the LCD panels by vacuum pressure, the interleaving sheet should be removed manually. Disclosure of Invention
Technical Problem
[6] An object of the present invention is to provide a conductivity foam sheet produced by mixing a polyolefin resin with carbon black having a conductive property and foaming the mixture such that a raw fabric is provided with conductivity and has a thickness of 0.3 to 2 D, and usable as an antistatic interleaving sheet of LCD panels. Best Mode for Carrying Out the Invention
[7] The present invention mixes a polyolefin resin as a basic resin, 5 to 30 parts by weight of carbon black as a conductive material and 3 to 30 parts by weight of a foaming agent, foams the mixture with a foam magnitude of 5 to 30 times to produce an antistatic foam sheet with a thickness of 0.3 to 2 D, and uses the antistatic foam sheet as an interleaving sheet of LCD panels, wherein the antistatic foam sheet has a surface resistance of 104 to 10e12Ω/D and a volume resistance of 10 to 10e12Ω-D, and micro- protrusions are formed on the surface of the antistatic foam sheet in the shape of cells having circular structures.
[8] The present invention relates to an antistatic foam sheet interposed between LCD panels arranged horizontally to provide cushioning and antistatic performance, and in particular, to a foam product appropriate for packing various glass substrates, for example a glass plate, a color filter, a TFT (Thin Film Transistor) substrate, LCD/PDP (Plasma Display Panel) panel, a panel for a liquid crystal cell of a glass substrate for a plasma display product, or panels produced using the various glass substrates, as well as an electronic component sensitive to static electricity.
[9] In other words, to move an electronic component sensitive to static electricity, a conductive polymer or an antistatic material should be used to absorb shock and prevent static electricity, and in the case that the conductive polymer or antistatic material is not used, an electronic product is damaged by static electricity during modularization or by shocks during delivery, and therefore, the present invention provides an antistatic foam sheet to give an electronic product a cushioning performance for absorbing shock and an antistatic performance for preventing static electricity.
[10] In particular, the present invention eliminates a conventional vertical arrangement of LCD panels, and instead arranges the LCD panels horizontally and interposes an antistatic foam sheet between the LCD panels to create cushioning and antistatic effects, and the present invention forms microprotrusions on a surface layer surrounding carbon to allow an easy removal of the antistatic foam sheet in an
automation system using vacuum absorption.
[11] The antistatic foam sheet of the present invention is produced by mixing a polyolefin resin as a basic resin, 5 to 30 parts by weight of carbon black as a conductive material and 3 to 30 parts by weight of a foaming agent, and foaming the mixture with a foam magnitude of 5 to 30 times, and the foam sheet has a thickness of 0.3 to 2 D.
[12] Here, various foam magnitude can be applied, however in the case that the foam magnitude is less than 5 times, it is not preferable because a desired object such as lightweight or protection (cushioning) of a glass substrate is not sufficiently achieved, in the case that the foam magnitude is more than 30 times, it is not preferable because strength and elasticity are insufficient, and therefore, it is preferable to foam with a foam magnitude of 5 to 30 times in consideration of a shock absorbing performance and an automation system of the antistatic foam sheet, in addition, it is preferable to produce an antistatic foam sheet with thickness of 0.3 to 2 D in consideration of a shock absorbing performance, the packing number and an antistatic performance.
[13] As mentioned above, the antistatic foam sheet of 0.3 to 2 D thickness produced by foaming a mixture including a polyolefin resin as a basic resin, 5 to 30 parts by weight of carbon black as a conductive material and 3 to 30 parts by weight of a foaming agent with a foam magnitude of 5 to 30 times is consisted of closed cells, which surround carbon particles, and thus, the carbon particles do not fall off after a long- term use, antistatic characteristics exhibit permanently and a surface transfer phenomenon occurred to the conventional antistatic film is prevented, thereby ensuring stability of a product.
[14] And, the antistatic foam sheet of the present invention has a surface resistance of 10
4 to 10e12Ω/D and a volume resistance of lόto 10e12Ω-D, and here, it means the antistatic foam sheet having both of the surface resistance and volume resistance can allow flow of electric charge in four directions, that is, the antistatic foam sheet has antistatic characteristics in whole.
[15] And, the antistatic foam sheet of the present invention has microprotrusions formed on a surface layer thereof so that the antistatic foam sheet can be easily removed from an absorption nozzle when vacuum absorption is blocked.
[16] The antistatic foam sheet of the present invention is used as an interleaving sheet of
LCD panels arranged horizontally to provide cushioning and antistatic functions, and in the case that LCD panels are arranged horizontally, the LCD panels can be loaded in the same space twice or more in quantity than a vertical arrangement.
[17] That is, the antistatic foam sheet of the present invention is interposed between
LCD panels to prevent surface scratch and static electricity of the LCD panels, and in the case that the LCD panels are arranged horizontally, the LCD panel is wholly
contacted with an interleaving sheet, thereby improving stability against shocks.
[18] The antistatic foam sheet of the present invention is consisted of porous foam cells having circular structures and has microprotrusions formed on a surface layer surrounding the cells and carbon, and when the antistatic foam sheet is interposed between the LCD panels as an interleaving sheet, the microprotrusions containing air on the surface thereof prevents the antistatic foam sheet from sticking onto the surface of the LCD panel, and thus the antistatic foam sheet is easily removed from the LCD panel, and in the case of an automation system using vacuum absorption, after the LCD panel is moved using vacuum pressure, the antistatic foam sheet is absorbed and moved using vacuum pressure, and when the vacuum pressure is blocked, the antistatic foam sheet is easily removed from a vacuum nozzle due to the microprotrusions, thereby realizing an automation system.
[19] As mentioned above, the present invention produces an antistatic foam sheet with thickness of 0.3 to 2 D by foaming a mixture including a polyolefin resin as a basic resin, 5 to 30 parts by weight of carbon black as a conductive material and 3 to 30 parts by weight of a foaming agent with a foam magnitude of 5 to 30 times, wherein the antistatic foam sheet has a surface resistance of 10 to 1Oe Ω/D and a volume resistance
4 19 of 10 to 1Oe Ω-D, and the antistatic foam sheet is used as an interleaving sheet interposed between LCD panels arranged horizontally to obtain cushioning and antistatic effects.
[20] That is, the present invention produces a thin antistatic foam sheet with cushioning and antistatic functions, and uses the antistatic foam sheet as an interleaving sheet of LCD panels, and in particular, the antistatic foam sheet of the present invention serves as an interleaving sheet of LCD panels arranged horizontally to provide cushioning performance for absorbing shock and antistatic performance for preventing static electricity.
