本発明は粘性液体の塗布装置に関し、特に低沸
点有機溶媒溶液の塗布装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a coating device for viscous liquids, and more particularly to a coating device for low-boiling organic solvent solutions.
粘性液体の塗布液をウエブ等の支持体面に延展

式の塗布装置も各種知られている。
There are various coating methods for spreading a viscous liquid coating onto the surface of a support such as a web, and there are also various known coating apparatuses that extrude the coating liquid from a distribution slit, allowing simultaneous multi-layer coating.

特殊なスライドホツパー（特開昭58−180262号）
等々、塗布及び塗布液の要件に合せて各種の形態
の塗布装置が挙げられる。 For example, an extruder directly delivers the coating liquid onto the support web from a plurality of slits opened in the lip of a coater die, an extruder extrudes each coating liquid from a plurality or single slit, and stacks the slide surface with a descending slope, or a single extruder A slide hopper that casts the coating in layers and passes it from the lip of the slide surface to the support web, and a coating device that is a combination of the above two methods, or the slide hopper so that the slide surface is not a downward slope but is horizontal. Special slide hopper (Japanese Patent Application Laid-open No. 180262/1983)
Various types of coating apparatuses can be used depending on the requirements of the coating and the coating liquid.
しかしこれらの塗布装置には夫々に欠点を有し

条件の制御も難しくまた装置のコストも高くな
る。 However, each of these coating devices has drawbacks. For example, in the extruder, the gap between the lip of the coater die and the support web must be controlled to less than twice the undried film thickness. Therefore, in the case of thin film coating, strict mechanical precision of the gap is required, and the coating conditions must be controlled. is also difficult and increases the cost of the equipment.

く、縦すじ或は斑状の膜厚むらが生じ易い。 Slide hoppers also have low boiling points (e.g. 40~
When applying an organic solvent or solution at a temperature of 95°C, the flow of the casting liquid is likely to be disturbed due to evaporation of the solvent, etc., and vertical streaks or uneven film thickness are likely to occur.

The disadvantages of the slide hopper may be expressed in combination or as they are.

供することにある。
An object of the present invention is to provide a coating device that has high coating quality, provides a coating film with uniform thickness without coating unevenness even when coating an organic solvent solution, is easy to operate, and is inexpensive.

れる。
The object of the present invention is to apply a coating liquid whose main component is dissolved in a low boiling point organic solvent in a coating device that transfers a coating liquid film from the casting surface lip of the coating liquid onto the surface of a running web. This is achieved by a coating device for a low boiling point organic solvent coating liquid, characterized in that the length of the casting surface from the slit extruded onto the casting surface of the coating device to the lip of the casting surface is 0.5 to 10 mm. .
本発明を構成するに当つて、エクストルーダ

そのスライドホツパー等のスリツトからリツプま
での長さが長い方式に於ては、確実に膜厚むらを
発生する。 In constructing the present invention, compared to the slide hopper method or the composite or modified slide hopper method, the extruder can be applied using the same organic solvent solution as other methods as far as coating unevenness is concerned. There is little or no vertical unevenness or patchy film thickness unevenness, giving good coating quality. This causes uneven film thickness.
この原因は、スライドホツパー方式に於て塗布

延距離を充分短かくすること即ちスリツトからリ
ツプまでの距離を短かくすることによつて確実に
膜厚むらの発生を防止しうることが明らかになつ
た。 The reason for this is that in the slide hopper method, the coating liquid is extruded from the distribution slit, and while it is being cast on the slide surface, the liquid is spread due to the non-uniformity of the surface tension that occurs between the slit and the lip due to the evaporation of the organic solvent. It was confirmed that there is a layered change in physical properties such as flow and viscosity in the thickness direction of the cast coating solution, and it is necessary to shorten the casting distance of the coating solution sufficiently, that is, shorten the distance from the slit to the lip. It has thus become clear that the occurrence of film thickness unevenness can be reliably prevented.
従つて前記要因に基き本発明に於ては、分配ス
リツトからリツプまでの流延距離の最適条件は、
用いる有機溶媒の種類（沸点の高低）、雰囲気温
度、換気条件、塗布液の粘度、塗布速度と未乾燥
膜厚等を勘案し実験的に求められるものである。 Therefore, based on the above factors, in the present invention, the optimum conditions for the casting distance from the distribution slit to the lip are as follows:
It is determined experimentally by taking into consideration the type of organic solvent used (high or low boiling point), ambient temperature, ventilation conditions, viscosity of the coating liquid, coating speed, undried film thickness, etc.
例えば他の要件の変動を補償し且つ実用的範囲
として95℃程度の沸点を有する有機溶媒溶液の場
合に流延距離は0.1〜10mm、更に好しくは0.5〜７
mmの範囲に収る。10mmより長ければ塗布むらの発
生があり、0.1mmより短かければ定常流延に達し
がたくまたダイスのコスト高を招く。 For example, in the case of an organic solvent solution that compensates for variations in other requirements and has a boiling point of about 95°C as a practical range, the casting distance is 0.1 to 10 mm, more preferably 0.5 to 7 mm.
It falls within the mm range. If it is longer than 10 mm, uneven coating will occur, and if it is shorter than 0.1 mm, it will be difficult to achieve steady flow and the cost of the die will increase.
