Embodiment 1

[0044] In Example 1, antimony-doped tin oxide particles with a particle diameter of 3 μm were surface treated with an acrylate silane coupling agent. Here, 5 g of the tin oxide was surface-treated with 0.1 g of silane having a methacrylate functional group, and then mixed with 30 g of methyl cellosolve, 2.5 g of epoxy resin and 0.75 g of curing agent to prepare an antistatic coating solution . Next, the antistatic coating solution was coated on the surface of the polyimide film with a thickness of 125 μm to a thickness of 1.0 μm to form an antistatic layer, thereby manufacturing an antistatic polyimide film.

[0045] The surface resistance of the polyimide film produced by the above method was measured to be 10 8 ohm / □. The film was cut to a predetermined size, put into 5% aqueous sodium hydroxide solution, and sonicated for 90 minutes, and then its surface resistance was measured to be 10 8 ohm / □, no change in resistance.

Embodiment 2

[0047] In Example 2, carbon nanotubes are used instead of tin oxide as the antistatic agent. Example 2 was the same as Example 1 except that the carbon nanotubes were acid-treated, followed by surface treatment with an epoxy silane coupling agent, and 0.7 g of the treated carbon nanotubes were mixed and used.

[0048] The surface resistance of the polyimide film produced by the above method was measured to be 10 9 ohm / □. The film was cut into a predetermined size, placed in a 5% aqueous sodium hydroxide solution, and sonicated for 90 minutes, followed by measurement of its surface resistance. As a result, no change in its surface resistance was observed, which was 10 9 ohm / □.

Embodiment 3

[0050] Example 3 is the same as Example 1, except that glycidoxypropyltrimethoxysilane (which is an epoxy silane coupling agent) is used as a coupling agent.

[0051] The surface resistance of the polyimide film produced by the above method was measured to be 10 8 ohm / □. The film was cut into a predetermined size, placed in a 5% aqueous sodium hydroxide solution, and sonicated for 90 minutes, followed by measurement of its surface resistance. As a result, no change in its surface resistance was observed, which was 10 8 ohm / □. In addition, the film was cut into a predetermined size, placed in a 10% potassium hydroxide aqueous solution, and sonicated for 90 minutes, and then its surface resistance was measured. As a result, its surface resistance was observed to be 10 9 ohm / □. Therefore, it was found that the surface resistance of the polyimide film did not significantly change, and thus, the polyimide film could withstand a high concentration of alkaline aqueous solution. ...

Abstract

The present invention provides an antistatic composition which can be used in washing processes using alkaline aqueous solution, that is, can be used to manufacture antistatic polymer products which can resist basic solvents, and antistatic polymer products manufactured by the same. The antistatic composition includes 0.1-20 parts by weight de metal oxides or carbon nanotubes; 0.5-20 parts by weight of a thermosetting resin; 0.02-5 parts by weight of a curing agent; and 55-99.38 by weight of a solvent, in which the antistatic composition is applied on a surface of a base polymer using a solution and can be reused without a change in surface resistance after a washing process using an alkaline aqueous solution.

Description

technical field [0001] The present invention relates to an antistatic composition and an antistatic polymer product prepared by using the antistatic composition. The antistatic composition can be cleaned with an alkaline aqueous solution such as an aqueous sodium hydroxide solution or an aqueous potassium hydroxide solution, more specifically In particular, it relates to antistatic compositions that can be used in cleaning processes using alkaline aqueous solutions, ie, can be used to manufacture antistatic polymer products that are resistant to alkaline solvents. Background technique [0002] Polymer films for electrical and electronic parts or polymer products made using the polymer films are used in a state where an antistatic layer is formed on their surfaces in order to prevent static electricity from occurring during the manufacturing process Problems arise that cause atmospheric dust to adsorb thereto and current breakdown. Various techniques are used to form an elec...
