Abstract

PURPOSE:To make a solvent or heating unnecessary, and to obtain a uniform thin film on an object to be coated, by discharging an original liquid of a solvent type adhesive as it is from a slot nozzle. CONSTITUTION:An original liquid G of a solvent type adhesive is injected as it is into a tank 15 without diluting the liquid G by a solvent. This liquid G is sucked up by a pump 1, is heated, and is transferred to discharge devices 5A, 5B through pressure resisting hoses 2a, 2b and 2c. Subsequently, from slot nozzles 8A, 8B fitted to the discharge devices 5A, 5B, an original liquid 5 is discharged onto the surface of an object to be coated F running along its lower part. In this way, a uniform thin film is applied on the object to be coated.

■ Wheel transfer method This is a method in which approximately the same amount of solvent is added to a commercially available general solvent-based adhesive and wheel transfer is performed at room temperature. Although this method has been widely used for a long time, it has various drawbacks: it is difficult to apply a thin layer, the adhesive tends to become hard and loose, and the thickness of the coating film is uneven. Furthermore, after coating, a drying device is required to remove the solvent contained in the coating, which inevitably poses a problem of pollution of the working environment.

■Honotomelt method This is a method that has recently become popular. That is, this is a method in which a pellet-shaped adhesive resin is heated (160° C. to 180° C.), melted and pressurized using a photomelt applicator, and then applied in a strip through a discharger and a slot nozzle attached thereto. According to this method, a relatively uniform coating film can be obtained, but as mentioned above, the power for heating and melting the resin is consumed, and in the case of products using the adhesive type resin,
The usage conditions are limited to 5℃ to 150℃,
We are currently researching and developing a resin that can be used at temperatures below 5°C.

The method of the present invention will be explained with reference to the drawings. Please refer to FIG. The figure shows a case where room temperature adhesive is applied in strips on both sides of a long plastic film F. First, in tank 15, stock solution G of solvent-based adhesive (commercially available product) is added.
is poured and sucked by the pump 1 at room temperature, and at the same time pressurized to an appropriate pressure and pumped through the pressure hose 2a. On the way, it is filtered 7 times through a filter 6 and reaches the insides of the dischargers 5A and 5B. The discharger is a solenoid valve 7
Pneumatically actuated valves 6A and 6B, which are operated by A and 7B, are incorporated to open and close the discharge passage for the solvent-based adhesive. If "Open" is selected, use the slot nozzle 8 A for solvent-based adhesive.
, 8B in a film form and applied onto the running long plastic film F. f'L7. ). Since the applied solvent-based adhesive, that is, the coating film, does not contain an excessive amount of solvent, there is no need to remove the adhesive as in the conventional method, that is, there is no need for post-treatment, and the coating film does not contain an excessive amount of solvent. immediately becomes a product.

Next, the main points of the experiment according to the above invention will be described. As the solvent-based adhesive, an acrylic adhesive (trade name, manufactured by Ipposha Yushi Kogyo Co., Ltd., Insol R-50) was used. In conventional wheel transfer devices, this acrylic solvent-based adhesive was diluted by adding the same amount of solvent toluene. Therefore, after wheel transfer, ie, coating, the excess solvent was removed by evaporation through a drying device. The power consumed by the drying device cannot be generalized depending on the size of the device, but a drying device with a length of about 4 m required about 9 kW.
