Description

FIELD OF THE INVENTION [0001] The present invention relates to an electrostatic anti-

The present invention relates to an antistatic film aging apparatus, and more particularly, to an apparatus for aging an antistatic film by adsorbing moisture to a film by supplying heat and moisture.

Conventionally, in order to produce an antistatic film (antistatic agent-treated film), an antistatic agent is mixed with a raw material and transferred to the film surface to produce a film having a hydrophilic group. At this time, the surface of the film meets the water molecules in the air, and these water molecules are connected to each other to discharge the static electricity generated from the film surface to the outside.

In order to produce such a film, proper temperature and humidity must be maintained. In general, since the humidity is low in winter, it takes a long time to adsorb water molecules on the surface of the film and the film is not sufficiently adsorbed. In addition, at a low temperature, there is a problem that the time required for the antistatic agent to migrate to the outside of the film is considerable, resulting in a decrease in productivity.

Further, the film is subjected to corona treatment (so-called discharge treatment) in order to adsorb a lot of moisture. The corona treatment is a method of generating a corona salt by using a discharge processor and passing the film through it to modify the surface. When the corona treatment is performed, the surface of the film is oxidized to increase the surface area of the film. On the surface of the film having increased surface area, the adsorption amount of water increases, and the generation of static electricity is further reduced.

At this time, the first heater unit 110 must be spaced from the film by a certain distance to avoid breakage due to contact of the film with the first heater unit 110. Accordingly, the first heater unit 110 is spaced apart from the film by a predetermined distance. In addition, a safety net (not shown) may be provided between the film and the first heater unit 110 to prevent the film from directly contacting the first heater unit 110. The safety net may be formed in a variety of shapes. In order that the heat of the first heater unit 110 can be transmitted to the film, it is preferable that the safety net is formed in a net shape.

The second heater unit 220 is provided below the roller 210 and the safety net 250 is provided between the roller 210 and the second heater unit 220. The safety net 250 serves to prevent the film from being damaged by direct contact with the second heater unit 220. The safety net 250 is formed in various shapes, and it is preferable that the heat of the second heater unit 220 is formed in a net shape in order to transmit the heat to the film.

The steam unit 230 supplies steam to the film. The steam unit 230 is connected to a steam device (not shown) inserted into a lower portion of one side of the lower body 200, and steam is supplied to an end of the steam line.

[

The internal temperature of the antistatic film aging apparatus 10 is most preferably between 50 and 120 ° C. The reason is that if the temperature is too low, the film will not be adsorbed well and the anti-static will not be done properly. If the temperature is too high, the film may be damaged by the high temperature.

In addition, in the interior of the antistatic film aging device 10, the water formed by the steam part 230 is floated on the bottom surface, and the water is discharged to the outside through the water outlet 260 formed on the bottom surface. In addition, the inner bottom surface of the antistatic film aging device 10 has a predetermined inclination relative to the ground surface, and the water flows downward in the direction of the water discharge port 260 by the inclination, As shown in FIG.

In addition, it is preferable that the internal temperature of the anti-static film aging device 10 is set between 50 and 120 ° C.
