Problems solved by technology

[0004] In the above-mentioned production process of PU coated gloves, dimethylformamide (DMF) needs to be used as a solvent, and DMF is highly toxic and pollutes the environment after volatilization in the production process. If there is DMF residue in the gloves, workers can wear it Absorbed through the skin and respiratory tract, it will damage the liver function and adversely affect the health of workers

Embodiment 1

[0047] Embodiment 1: as figure 1 Shown, a kind of dipped gloves production technique comprises the steps:

[0048] a. Glue dipping: Put the gloves to be dipped on the hand model, and immerse the palm of the glove on the hand model in the water-based PU glue at room temperature, and the dipping time is 1 second;

[0049] b. Glue dispensing: Lift the hand model into the air to make the excess water-based PU glue drip clean, and the dispensing time is 40 seconds;

[0050] c. Uniform glue: Make the hand mold rotate 360 ​​degrees, so that the water-based PU glue is evenly distributed on the surface of the palm of the glove, and the glue uniform time is 25 seconds;

[0051] d, soaking coagulant: immerse the gloves in the step c in the coagulant, and the soaking time of the coagulant is 2 minutes;

[0052] e. Dropping coagulant: Lift the hand model into the air to make the excess coagulant drip clean, and the time for dripping the coagulant is 2 minutes;

[0053] f. Water washing:...

Embodiment 2-12

[0057] Example 2-12: A production process for dipped gloves, the difference from Example 1 is that the components and weight percentages of the water-based PU glue and coagulant are shown in Table 1.

[0058] Each component of water-based PU glue and coagulant and its weight percent in the embodiment 1-12 of table 1

[0059]

Embodiment 13

[0060] Embodiment 13: A production process of dipped gloves, the difference from Example 3 is that the dipping time in step a is 2 seconds.

Abstract

The invention discloses a production process of rubber-dipped gloves, which comprises the following steps: a. Dipping: put the gloves to be dipped on a hand mold, and immerse the palm of the gloves on the hand mold into water-based PU glue at normal temperature Middle; b, glue dropping: lift the hand model into the air, so that the excess water-based PU glue drips clean; c, uniform glue: make the hand model rotate 360; d, soak the coagulant: soak the gloves in step c to solidify e, dripping coagulant: lift the hand model into the air, so that the excess coagulant drips clean; f, washing: immerse the gloves in the sink for washing; g, drying: put the hand model and gloves in the oven Drying moisture; h, demoulding: the glove after drying is taken off from hand mold, obtains the dipped glove. There is no DMF volatilization in this process, and there is no DMF residue in the produced gloves, which avoids damage to the health of workers and is environmentally friendly and pollution-free; the gloves have excellent wear resistance and tear resistance; the gloves are soft but not sticky, dry and breathable.

Description

technical field [0001] The invention relates to the technical field of glove processing, more specifically, it relates to a production process of rubber-dipped gloves. Background technique [0002] PU coated gloves are also called PU rubberized gloves or PU finger and palm gloves. Gloves completely cover the palm part with specially treated polyurethane, which can provide good anti-slip performance and prevent hand sweat and particles from the palm of the human body. pollute. [0003] A Chinese invention patent with the notification number CN104287228A discloses a nitrile-reinforced PU-coated glove and its production process. Immerse the index finger and the tiger's mouth with the treatment solution. After the treatment solution is dried, dip the thumb, index finger and the tiger's mouth with the nitrile rubber solution. The dipping time is 0.2s. After dipping, turn the hand to touch it so that the glue is not random. Flow, then dry and vulcanize at 90-110°C for 1-2 hours,...
