Definitions
- the present invention relates to a method for inspecting a coating film defect of a resin coated film comprising a film and a coating film formed by coating a resin solution thereon.
- a resin-coated film obtained by coating a film with a solution containing a heat-resistant nitrogen-containing aromatic polymer and a ceramic powder to form a coating film is non-water It is used as a separator for electrolyte batteries. If the coating film of the heat-resistant separator has defects such as pinholes and peeling, the heat resistance is lowered, and the safety when used in a battery may be lowered.
- the resin-coated sheet obtained by applying the resin to the release sheet is used for the production of the pre-preda.

- alamide aromatic polyamide
- the ceramic powder is alumina.
- Alumina fine powder is added to a polar organic solvent solution such as N-methyl-2-pyrrolidone of aromatic polyamide to form a slurry, which is then applied to a porous polyethylene film by a coating method using a bar, knife or die. After coating and precipitation of the polymer, the polar organic solvent is removed and dried to produce a resin coated film.
- a polar organic solvent solution such as N-methyl-2-pyrrolidone of aromatic polyamide
- the thickness of the resin coated film is about 5 to 100 ⁇ m, and the coating thickness is not clear because fine particles of alumina and alumina are dispersed in the porous polyethylene film. 1 ⁇ ! About 50 ⁇ m.
- the film may have defects such as film peeling and streaks.
- a defect is detected by irradiating the coating light with inspection light having a peak wavelength of emission intensity in the range of 385 to 415 nm and detecting the reflected light.
- Figure 1 is a schematic diagram showing a method for inspecting coating film defects.
- a coating film made of polyamide and alumina is provided on the porous polyethylene film 2.

- the defect is detected by processing in (not shown). Defect inspection can be carried out continuously while transporting a long resin-coated film, or batchwise of a single-coated resin-coated film.
- the coating surface When the coating surface is irradiated with the above inspection light, there is a difference in reflectance between the coating normal part and the defective part, so by observing the reflected light with a CCD camera and detecting the intensity difference, the coating defect The part can be detected.
- FIG. 2 is a diagram showing the wavelength region of the inspection light
- etc. 6 is the relative intensity of the inspection light having a peak wavelength of 400 nm used in the present invention, and 7 is the conventional wavelength range of 30.

- the reflectance is a value measured using a spectrophotometer MPC-2200 (manufactured by Shimadzu Corporation).
- the relative sensitivity of the CCD camera is large at the wavelength of 400 nm, and the difference between the reflectance of the porous polyethylene film and the reflectance of the coating film is also the wavelength of 3500 nm and the wavelength of 400 nm. Since it is equal to or better than nm, it is considered that the detection sensitivity of defects is improved by using inspection light with a peak wavelength of 400 nm.
- Defect inspection was performed on a resin-coated film in which a coating made of alumina and alumina was formed on a porous polyethylene film with a coating thickness of approximately 1 mm long X approximately 0.5 mm wide. .
- a light source is placed approximately 10 cm above the resin-coated film for irradiation, a CCD camera is placed at a position where the reflection angle is 13 ° at a height of 80 cm, and the reflected light is imaged. Processed.
- Image processing device (Nagase Sangyo Co., Ltd.)
- Figure 3 shows the detected image and the detected waveform. This defect could be clearly detected when irradiated with inspection light with a peak wavelength of 400 nm and a peak wavelength of 39 2 nm. On the other hand, when the conventional inspection light with a peak wavelength of 3500 nm was irradiated, this defect could barely be detected, but if it becomes smaller than this defect, it may not be detected.
