Embodiment 1
[0029] A kind of production technology of waterborne polyurethane coated gloves, concrete steps comprise;
[0030] 1. Preheating: Put the fabric glove core on the hand mold, enter the drying tunnel, set the temperature of the drying tunnel to 60 degrees Celsius, and preheat for 10 minutes.
[0031] 2. Soak the coagulant. The coagulant is a volatile organic acid; mix 94 parts of water and 6 parts of formic acid evenly and put it in the coagulant tank of the assembly line; until no liquid drips out.
[0032] 3. Baking: the hand mold enters the oven, the oven temperature is set at 60 degrees Celsius, and baked for 10 minutes.
[0033] 4. Glue dipping solution, the glue solution includes water-based polyurethane and water; the glue solution includes 100 parts of water-based polyurethane and 3 parts of additives, add a little of the selected color slurry as needed, stir evenly, and put it into the slurry tank of the production line. After leaving the drying tunnel, dip the hand m...
