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...

Abstract

The invention relates to a waterborne polyurethane coating glove and production process thereof. The production process comprises the following steps: a. preheating, i.e., putting a fabric glove core on a hand mold and preheating; b. dipping in a coagulator, wherein the coagulator is volatilizable organic acid; c. baking; d. dipping in glue liquid, wherein the ingredients of the glue liquid comprise waterborne polyurethane and water; e. drying; and f. demolding. The waterborne polyurethane coating glove is structurally made by coating the waterborne polyurethane coating on the fabric glove core. According to the invention, volatilizable organic acid is used as the coagulator instead of a calcium salt in the production process; organic acid can be volatilized and recycled during the production, so that the washing step is omitted; and a mechanical foaming waterborne polyurethane coating glove can be made. The waterborne polyurethane coating glove has the characteristics of excellent performance, soft manufactured product, wear resistance, simple production process and wide market prospect, and is environment-friendly, safe.

Description

technical field [0001] The invention relates to gloves and a production process thereof, water-based polyurethane coated gloves and a production process thereof. Background technique [0002] The rubber materials of dipped gloves currently on the market are mainly natural latex, nitrile latex, pvc paste resin and solvent-based polyurethane resin. Natural latex-dipped gloves feel soft, but have poor abrasion resistance, and the production process requires a large amount of rinsing wastewater; nitrile latex-dipped gloves have better abrasion resistance than natural latex, but the softness of nitrile latex-dipped gloves is not good , the production process requires a large amount of rinsing wastewater; PVC paste resin-impregnated gloves are not environmentally friendly and contain a large amount of plasticizers; solvent-based polyurethane contains a large amount of organic solvents, the production process has a great impact on the environment, and the product residues are harmf...
