Embodiment 1

[0122] In order to make the concentration of CNT1 0.05% by mass, in addition, make the concentration of sodium carboxymethylcellulose ("MAC 500LC" manufactured by Nippon Paper Industries Co., Ltd.) 0.05% by mass, add CNT1 and carboxymethylcellulose To ion-exchange water: 10g. The obtained mixed liquid was irradiated with ultrasonic waves for 1 hour using an ultrasonic disperser to prepare a carbon nanotube dispersion liquid.

[0123] Next, 10 g of the carbon nanotube dispersion liquid and the fluororesin dispersion liquid were mixed so that the content of the carbon nanotubes became 0.01% by mass relative to 100% by mass of the total of the fluororesin and carbon nanotubes. The obtained mixed solution was stirred for 1 hour using a magnetic stirrer and a rotor to prepare a fluorine-containing resin coating composition.

[0124] The obtained composition for coating a fluorine-containing resin was placed on a stainless steel plate (a bat made by Stenlace), and dried at 80°C. N...

Embodiment 2～5、 comparative example 1、2

[0126] Except that the carbon nanotubes used as raw materials and the content of carbon nanotubes are changed as shown in Tables 1 and 2, others are the same as in Example 1, and the fluorine-containing resin coating compositions of each example are produced, and the fluorine-containing resin coating compositions of each example are produced. A coated film was used as a test film.

[0130]

[0131] In Examples 1 to 5 in which the content of carbon nanotubes is within the range specified by the present invention, the surface resistivity of any coating film is less than 10 10 Ω / □, and the conductivity as a coating film is sufficient.

[0132] In Examples 4 and 5, the average fiber length of the carbon nanotubes was relatively long due to variations between batches. In Examples 4 and 5, even though the content of carbon nanotubes is relatively small, the surface resistivity is less than 10 4 Ω / □, the conductivity is more ex...

Abstract

In order to provide a composition for a fluororesin-containing coating which has low pollution by carbon nanotubes, has sufficient conductivity and has excellent workability during coating, this composition for a fluororesin-containing coating contains carbon nanotubes, a fluororesin, and a dispersion medium, and the content of the carbon nanotubes is 0.01-0.5 mass% with respect to the total 100 mass % of the fluororesin and the carbon nanotubes.

Description

technical field [0001] The present invention relates to a composition for coating a fluorine-containing resin, a coating film, and a substrate. Background technique [0002] Carbon nanotubes are used for various industrial purposes due to their excellent electrical conductivity. In addition, fluororesins have excellent chemical resistance and heat resistance. Therefore, in order to utilize the respective characteristics of carbon nanotubes and fluororesins, industrial utilization of compositions including carbon nanotubes and fluororesins has been proposed (Patent Documents 1 to 3). [0003] Patent Document 1 describes a method for producing a conductive fluororesin film. In the method for producing a conductive fluororesin thin film described in Patent Document 1, a carbon nanotube dispersion and a fluororesin dispersion are mixed, and the mixed dispersion is applied to a substrate and dried. [0004] Patent Document 2 describes a composite coating film. The composite c...
