A method for preparing a perfluorosulfonic acid proton membrane, characterized in that the steps are as follows:

Step 1: Prepare solution;

Put the perfluorosulfonic acid ion membrane resin into a reaction kettle, and then add diethylene glycol, ethanol, isopropanol, xylene, cyclohexanone, dimethyl sulfoxide, propylene glycol, dimethylformamide and water in sequence, and heat the mixture to a temperature of 90-200°C (the maximum temperature should not exceed 250°C);

Step 2: generating gel;

The mixed solution was stirred for 10 minutes and allowed to stand to cool naturally to obtain a perfluorosulfonic acid ion membrane resin gel;

Step 3: extruding the film;

The perfluorosulfonic acid ion membrane resin gel is added to the extruder as a whole, and then the molten raw material is extruded through the extruder as a whole, and then transported through the machine body;

Step 4: conveying and calendering;

During the transportation, the excess heat outside the electric heater is blown to the inside of the second shell through the air supply operation of the air outlet, and the hot air flow is refluxed through the spoiler to keep the outside of the raw material warm and avoid hardening of the outside of the raw material. The raw material is added to the calender through the machine body for calendering and film forming;

The hardened area will cause local rupture and damage to the surface of the membrane during film formation, thereby affecting the quality of the perfluorosulfonic acid proton exchange membrane after film formation.

1. By providing a heat circulation component and a blowing component, through the setting of the through hole, while not affecting the normal heat discharge of the electric heater, the heat can also be transferred to the body through the second shell to avoid hardening of the outer surface of the raw material. At the same time, through the setting of the spoiler, when the hot air flow contacts the spoiler, the arc-shaped setting of the spoiler buffers the hot air flow, so that the hot air flow refluxes, and the air is blown to the inside through the air outlet, so that the excess heat on the surface of the electric heater can be moved to the inside of the second shell, and the heat can also be dissipated to the outside of the electric heater to avoid damage to the electric heater caused by excessive heat accumulation;

2. A transmission assembly is provided, and the rack plate is driven to move by an electric push rod. Under the action of the meshing connection between the gear 2 and the rack plate, the chuck 1 and the chuck 2 are engaged to drive the gear 1 to rotate, so that the shaft 3 and the gear 5 rotate synchronously to drive the thermal cycle assembly and the displacement assembly to work;

3. By providing a displacement component and a dredging component, through the threaded connection between the screw sleeve 2 and the screw rod 2, the sleeve rod is driven to move, so that the shaft rod 1 and the sleeve rod are offset, so that the top block 2 blocks the mold and extrude the residual material inside. At the same time, the top block 2 drives the inner sleeve to move, so that the holes correspond to the vent pipe 1, the vent pipe 2 and the sewage outlet one by one, so that the vent pipe 1 and the vent pipe 2 are convenient for injecting gas into the barrel. At the same time, the residual material in the silo and the barrel is cleaned by flushing the outside through the water port, and the internal water flow rolls under the action of the injected gas to flush the internal residual material, thereby improving ease of use and applicability.

Step 3: extruding the film;

The perfluorosulfonic acid ion membrane resin gel is added to the extruder body 1, and then the molten raw material is extruded through the extruder body 1 and then transported through the body 202;

Step 4: conveying and calendering;

During the transportation, the air outlet 602 is used to supply air, and the excess heat outside the electric heater 105 is blown to the inside of the second shell 402, and the hot air flow is refluxed through the spoiler 404 to keep the outside of the raw material warm and prevent the outside of the raw material from hardening. The raw material is added to the calender through the machine body 202 for calendering and film forming;

Step 5: Film forming and shaping;

The perfluorosulfonic acid ion membrane is obtained by evaporating the solvent in the perfluorosulfonic acid ion membrane resin gel using a hot roller and a hot channel.

Working principle: When working, by connecting to an external blowing device, the wind is discharged from the inside of the air outlet 602, so that the excess heat on the outer surface of the electric heater 105 is blown to the inside of the second shell 402, and the heat is refluxed through the arc-shaped spoiler 404, so that a large amount of hot air is gathered inside the second shell 402, so as to avoid hardening caused by a large temperature difference when the raw material is extruded;

During operation, when it is necessary to clean the internal residual material, the electric push rod 512 is driven to drive the rack plate 511 to move, and the gear 2 510 and the rack plate 511 are meshed and connected, so that the chuck 1 503 and the chuck 2 504 are engaged, thereby driving the gear 1 502 to rotate. When the gear 1 502 rotates, the surrounding gears 5 704 and gear 3 513 are driven to rotate, so that the internal screw sleeve 2 702 and the screw 2 703 are threadedly connected, and the driving sleeve rod 109 is driven on the outside of the shaft rod 108. The second top block 112 moves to block the mold 104. During the blocking, the inner sleeve 712 moves synchronously so that the hole corresponds to the vent pipe 1 807, the vent pipe 2 808 and the drain port 810. At this time, the air pump connected to the outside of the connecting pipe 4 809 works to inject gas into the interior. At the same time, the connecting pipe 3 806 injects water into the interior, and water is sprayed out from the water port 802 to flush the interior. The water forms a tumbling water flow together with the gas to continuously flush the interior and clean the residual material.

During operation, gear three 513 drives gear four 515 to rotate, and shaft three 412 is driven to rotate under the action of the pulley transmission structure 517, so that the worm 411 and the worm wheel 408 are meshed and connected, so that the shell two 402 moves upward, exposing the entire extruder 1, which is convenient for external inspection, and the operation is completed.
