Problems solved by technology

[0026] The above technical solution is easy to operate and easy to use, but because the glove is only immersed in a coating agent, the structure is not strong, and the coating on the surface of the glove is very easy to fall off, resulting in the inability to achieve the protective effect of the coating

Embodiment 1

[0055] Step S1, preparing the glove core: using polyester-cotton blended material, and processing it into a glove blank by 10-pin, 13-pin, 15-pin or 18-pin knitting;

[0056] Step S2, mold preheating: put the knitted glove core on the hand mold, and preheat at 30-40°C for 30 minutes;

[0057] Step S3, soaking the coagulant: dipping the hand mold covered with the glove core into the coagulant, the coagulant is cleaned by a metal salt in 12 parts by weight of sodium chloride, potassium chloride, aluminum sulfate or magnesium sulfate Liquid, 1.5 parts of acrylic water-based adhesive, 2 parts of methanol and 84.5 parts of water;

[0058] Step S4, soaking and cleaning; soaking and cleaning the hand mold soaked in the coagulant, the solution used for soaking is pure water, and cleaning after soaking for 40 minutes;

[0059]Step S5, dipping solution: immerse the hand mold in step S4 into the water-based polyurethane glue solution, the preparation of the water-based polyurethane glue...

Embodiment 2

[0064] Embodiment 2 is basically the same as Embodiment 1, the difference is:

[0065] Step S5, glue dipping solution: immerse the hand mold in step S4 into the water-based polyurethane glue liquid, the preparation of the water-based polyurethane glue liquid first stirs 94 parts of water-based polyurethane with a solid content of 25% and 6 parts of silicone emulsion Mix evenly and fully, and then use 3-5 parts of thickener and 10 parts of water to adjust the viscosity to 2000mpa.s.

Embodiment 3

[0067] Embodiment 2 is basically the same as Embodiment 1, the difference is:

[0068] Step S5, glue dipping solution: immerse the hand mold in step S4 into the water-based polyurethane glue solution, the preparation of the water-based polyurethane glue solution first stirs 90 parts of water-based polyurethane with a solid content of 25% and 10 parts of silicone emulsion Mix evenly and fully, and then use 3-5 parts of thickener and 10 parts of water to adjust the viscosity to 2000mpa.s.

Abstract

The invention provides a production method and application of water-based polyurethane dipped gloves in the field of protective gloves, comprising: step S1, preparing glove core: using polyester-cotton blended material or all-chemical fiber material to produce glove core through knitting process; step S2 , mold preheating: put the glove core on the hand mold, and preheat; step S3, soak the coagulant: immerse the hand mold in the coagulant; step S4, soak and clean; step S5, soak the glue; Step S6, glue dropping; Step S7, drying; Step S8, demoulding, cooling to obtain rubber-dipped gloves. The gloves produced by the method of the invention have the advantages of super wear resistance, environmental protection, good air permeability, good color fastness, comfortable wearing, etc., and are convenient to operate, save energy, and reduce production costs of enterprises.

Description

technical field [0001] The invention relates to the field of protective gloves, in particular to the technical field of production of water-based polyurethane dipped gloves. Background technique [0002] Water-based polyurethane (WPU) uses water as a dispersant instead of organic solvents, and has the advantages of non-toxic, non-flammable, safe transportation, and environmental friendliness. insufficient. [0003] At the same time, due to the presence of water, water-based polyurethane has a longer drying time than solvent-based polyurethane. If water-based polyurethane with a high solid content is used as a material, there are disadvantages such as poor air permeability, and it also increases production costs. [0004] Therefore, how to develop and improve the shortcomings of the above-mentioned existing technologies is actually the goal that the relevant industries need to work hard to develop. In view of this, the designer of the application is thinking and creating ide...
