Referring to Figure 6, the method for manufacturing a water-soluble adhesive according to the present embodiment may use the above-described water-soluble adhesive manufacturing apparatus 10 (see FIG. 1), 100 parts by weight of water in a first raw material tank equipped with a stirrer, poly A first raw material preparation step of stirring the first raw material containing 3 parts by weight to 5 parts by weight of vinyl alcohol (PVA); A second raw material preparation step of stirring the second raw material including 100 parts by weight of water, 120 parts by weight to 130 parts by weight of vinyl acetate monomer and 20 parts by weight to 40 parts by weight of acrylate monomer in a second raw material tank equipped with a stirrer; The first raw material is batch-injected into the reaction tank, but the second raw material is divided into the reaction tank a plurality of times and then injected for 10 minutes to 30 minutes while stirring to produce an adhesive composition at a temperature of 75°C to 85°C. step; A mixing step of transferring the adhesive composition to a mixing tank equipped with a screw stirrer and stirring the adhesive composition in the mixing tank; An aging step of transferring the adhesive composition mixed in the mixing tank to an aging tank and aging the adhesive composition by changing the temperature and agitation speed in steps in the aging tank; And a cooling step of transferring the adhesive composition into a storage tank equipped with a nozzle for discharging the adhesive composition and maintaining it at 10°C to 20°C for 10 minutes to 30 minutes. The adhesive composition prepared by the method of preparing the adhesive composition may have a pH of 4 to 7 and a viscosity of 1,000 cps/25°c to 100,000 cps/25°c.

In the first and second raw material preparation steps, viscosity, temperature and pH of the first and second raw materials are measured by sensors provided inside the first and second raw material tanks, respectively, and the first and second raw materials are measured. It may further include adding water to the first and second raw material tanks according to the viscosity, temperature and pH of the. In the first and second raw material preparation steps, the viscosity, temperature, and pH of the first and second raw materials may be kept constant within a predetermined range so that the prepared adhesive composition has physical properties within design specifications.

The reaction step is carried out in a reaction tank, in which the first and second raw materials can be prepared with an adhesive composition while controlling the amount of reaction after receiving the first and second raw materials. The mixing tank may be mixed by adding a reinforcing agent such as nanoparticles to the adhesive composition in order to further mix the adhesive composition of which the reaction is completed in the reaction tank to have uniform physical properties, and further reinforce physical properties such as mechanical strength. The aging step may be performed in an aging tank, and may be controlled in various temperature ranges so that the adhesive composition discharged from the mixing tank can be aged.

The adhesive composition provided in the aging tank can be aged through an aging step that is stirred in multiple stages in various temperature ranges. In the aging step, it is possible to make the adhesive composition that is just prepared to maintain uniform physical properties as a whole. The aging step is a first step of stirring for 10 minutes to 30 minutes at a temperature of 75 ℃ to 85 ℃; A second step of stirring at a temperature of 50°C to 60°C for 10 minutes to 30 minutes; A third step of stirring at a temperature of 30°C to 40°C for 10 minutes to 30 minutes; And a fourth step of maintaining the pressure under reduced pressure at room temperature for 10 minutes to 30 minutes.

Before performing the aging step, the adhesive composition may be prepared and maintained at a high temperature, for example, 75°C to 85°C. When the temperature of the adhesive composition changes rapidly, the uniformity of the physical properties of the adhesive composition decreases, and a physical temperature difference between the outside and the inside of the adhesive composition may occur due to a sudden temperature change outside the adhesive composition.

On the other hand, in the aging step according to this embodiment may be performed in the first to fourth steps, the aging of the adhesive composition proceeds slowly by changing the temperature step by step in the process of performing the first to fourth steps It is possible to alleviate the property change. In addition, the inside of the aging tank can be depressurized through a pump provided in the aging tank, and substances evaporated from the adhesive composition are discharged to the outside through a hood, thereby reducing impurities contained in the adhesive composition to increase purity. .

Specifically, the aging step, the first step of stirring at a temperature of 75 ℃ for 10 minutes; A second step of stirring at a temperature of 55° C. for 10 minutes; A third step of stirring at a temperature of 35° C. for 10 minutes; And a fourth step of maintaining the pressure under reduced pressure at room temperature for 10 minutes. It is possible to maintain the same temperature difference at each step at 20°C and maintain it at the same time to improve the worker's work efficiency, and to prevent the difference in physical properties for each lot, thereby maintaining the uniformity of the process. .

Since the completed adhesive composition is delivered to the mixing tank, the aging tank, and the storage tank through the nozzles connected in the same phase from the lower side, the potential energy change caused by the drop from the top to the bottom, and the friction heat caused by it It is possible to prevent the occurrence of, it is possible to minimize the effect on the physical properties of the adhesive composition.

The adhesive composition that has been subjected to the aging step may be stored in a storage tank to perform a cooling step. The adhesive composition in the storage tank may be further washed with alcohol before the cooling step is performed. .

In the cooling step, the alcohol may include IPA or NMP in a volume of 2 to 3 times the volume of the adhesive composition. The alcohol is used in a volume of 2 to 3 times the volume of the adhesive composition. If less than 2 times, there is a finely chucked portion of the adhesive composition, and if the volume of 3 times is enough to wash the adhesive composition, it is 3 times. If it exceeds, unnecessary production cost can be increased.

The cooling step may be performed in a storage tank for storing and storing the adhesive composition discharged from the aging tank. The aging is completed, the adhesive composition is uniform in physical properties, a cooling step in which the storage tank is washed and cooled may be performed. The adhesive composition discharged through the storage tank may be individually packaged in a storage container conveyed through a conveyor transport unit. The conveyor transport unit measures the weight of the storage container and transfers the measured weight of the adhesive composition to the control unit, and the control unit compares the received weight of the measured adhesive composition with the preset weight range in the control unit to store the storage container. It is possible to control the weight of the adhesive composition accommodated.

The washing step included during the cooling step in the storage tank may include a first step of maintaining the adhesive composition in a storage tank equipped with the alcohol for 30 minutes to 60 minutes; A second step of filtering the alcohol of the first washing step to remove it from the storage tank and introducing the alcohol into a storage tank equipped with an adhesive composition; A third step of heating the storage tank provided with the adhesive composition and alcohol at 40 degrees for 30 minutes; A fourth step of filtering and removing the alcohol after cooling the storage tank at room temperature; And a fifth step of adding 10 parts by weight of water to the adhesive composition in the adhesive composition from which the alcohol has been removed.

The adhesive composition in which the washing step is performed in the storage tank may be performed in a cooling step of maintaining at 10°C to 20°C for 10 minutes to 30 minutes in the storage tank. In the cooling step, the adhesive composition whose temperature is gradually reduced in the aging step may be cooled. The adhesive composition cooled in the cooling step may be kept constant without deterioration in physical properties during transport and storage after packaging.

Preferably, the cooling step is maintained at 10°C to 20°C for 10 minutes to 30 minutes. When the temperature is less than 10°C, some adhesive composition solidifies to move the adhesive composition through a nozzle provided in the storage tank. It is difficult, and when it is higher than 20°C, it is difficult to secure the effect of maintaining physical properties for a long time by cooling. In addition, the time must be performed for 10 minutes to 30 minutes to realize the effect by the cooling step. Specifically, the cooling step may be performed at 10°C for 10 minutes.

The manufacturing method of the adhesive composition according to the embodiment of the present invention may further include the step of transferring the adhesive composition discharged from the nozzle of the storage tank to the storage container after the cooling step. The weight of the adhesive composition stored in the storage container is measured and transferred to a control unit, and the weight of the measured adhesive composition is compared with the weight previously input to the control unit to turn on/off the valve provided in the nozzle of the storage tank. It may further include the step of controlling.

The storage container may receive the adhesive composition discharged from the storage tank while being continuously transported through the conveyor transport unit. The conveyor transport unit may include a belt for transferring the storage container and a weight measurement unit for measuring the weight of the adhesive composition provided in the storage container.

The weight measuring unit may be provided on the belt to transfer the weight of the measured adhesive composition to the control unit. The control unit controls the weight of the adhesive composition provided in the storage container to be approximately constant by comparing the weight of the measured adhesive composition received with the weight previously input to the control unit, and controlling the valve provided in the nozzle of the storage tank. can do.

The weight of the adhesive composition accommodated in the storage container by the control unit can be easily maintained within a range previously input to the control unit.
