Protective glove for electric welding, and manufacturing method therefor

A method for preparing a welding protective glove, wherein the method comprises:

• Step 1, selection of raw materials;
• Step 2, preparation of a refined terephthalic acid/graphene oxide/ethylene glycol modified slurry;
• Step 3, esterification reaction:
• the slurry obtained in step 2 is added to a reactor, with repeated filling and emptying of nitrogen gas, air in the reactor is exhausted, and then nitrogen gas is filled and the temperature is raised to perform a pressurized esterification reaction;
• Step 4, condensation reaction:
• the temperature in the reactor is continued to be raised to perform a low vacuum condensation, the pressure in the reactor is reduced, and the temperature is raised at the same time, the reaction is then allowed to stand, the cast head is opened, nitrogen gas is filled until the polymer melt forms a stable fine stream, the polymer melt is cooled by a water tank, cut into granules by a granulator, and dried by a fan dryer, and then stored for use;
• Step 5, melt spinning:
• the modified graphene oxide flame-retardant polyester masterbatch obtained in step 4 is dried, then heated and melted, and then spun into filaments through a spinning box filter;
• Step 6, fabric preparation:
• the graphene oxide flame-retardant polyester filament obtained in step 5 is woven into a woven fabric through a shuttle loom;
• Step 7, post-treatment of the fabric:
• a flame-retardant finishing liquid is prepared, stirred, and then heated, and then the fabric is immersed in the finishing liquid, then passed through an immersion calender to squeeze out excess finishing liquid, and then dried by a dryer to obtain a high-flame-retardant fabric. Step 8, using the glove template, cut and sew the fabric obtained in step 7 to produce welding protective gloves.
