Embodiment 1

[0039] A kind of glove manufacturing process, described process comprises the steps:

[0040] 1) Prepare the coagulation solution for glove coating: the coagulation solution includes 35% calcium chloride by mass percentage, and the balance is methanol;

[0041] 2) preparing an impregnating solution for the glove coating, and foaming the impregnating solution; the components of the impregnating solution are water-based polyurethane and additives;

[0042] 3) After coating the condensate on the surface of the glove, dry it at room temperature for 0.5 minutes, then immerse it in the immersion solution, and spray sand on the immersion solution coating, so that the sand particles are evenly distributed on the immersion solution coating;

[0043] 4) Dry the gloves covered with the impregnating liquid coating at 76°C for 35 minutes, remove the sand particles, and release the impregnating liquid coating after drying.

Embodiment 2

[0045] A kind of glove manufacturing process, described process comprises the steps:

[0046] 1) Prepare the coagulation solution of the glove coating: the coagulation solution includes 16% calcium chloride by mass percentage, and the balance is water;

[0047] 2) preparing an impregnating solution for the glove coating, and foaming the impregnating solution; the components of the impregnating solution are water-based polyurethane and additives;

[0048] 3) After coating the condensate on the surface of the glove, dry it at room temperature for 5 minutes, then immerse it in the immersion solution, and make the immersion solution coating on the surface of the glove level;

[0049] 4) Dry the gloves covered with the dipping solution coating at 50°C for 55 minutes, and release the dipping solution coating after drying.

Embodiment 3

[0051] A kind of glove manufacturing process, described process comprises the steps:

[0052] 1) Prepare the coagulation solution for glove coating: the coagulation solution includes 30% calcium nitrate by mass percentage, and the balance is methanol;

[0053] 2) preparing an impregnating solution for the glove coating, and foaming the impregnating solution; the components of the impregnating solution are water-based polyurethane and additives;

[0054] 3) After coating the condensate on the surface of the glove, dry it at room temperature for 4 minutes, then immerse it in the immersion solution, and spray sand on the immersion solution coating, so that the sand particles are evenly distributed on the immersion solution coating;

[0055] 4) Dry the gloves covered with the impregnating liquid coating at 70°C for 40 minutes, remove the sand particles, and release the impregnating liquid coating after drying.

Abstract

The invention relates to a glove manufacturing technology. The glove manufacturing technology comprises the following steps of (1) preparing condensation liquid of a glove coating layer, wherein the component of the condensation liquid is soluble calcium ion salt and volatile solvent; (2) preparing impregnating liquid of the glove coating layer, and foaming the impregnating liquid, wherein the component of the impregnating liquid is waterborne polyurethane and additives; (3) drying a glove under the normal temperature after the condensation liquid is coated on the surface of the glove, impregnating the glove in the impregnating liquid, and enabling an impregnating liquid coating layer on the surface of the glove to be subjected to leveling or sanding treatment; (4) drying the glove which is coated with the impregnating liquid coating layer, and demolding after the impregnating liquid coating layer of the glove is dried. According to the glove manufacturing technology disclosed by the invention, the defect of traditional glove coating is overcome, the environment pollution is avoided, the safety of a human body during a long-time wearing process can be ensured, and excellent solvent resistance, excellent acid-base resistance and excellent abrasion resistance are obtained.

Description

technical field [0001] The invention relates to the technical field of gloves, in particular to a glove manufacturing process. Background technique [0002] Gloves as labor protection products are widely used in various industries. In order to achieve a certain protective effect or the flexibility of operation after wearing the gloves, the front of the gloves is coated with a coating. Usually the coating of gloves has solvent-based polyurethane coating, nitrile coating and latex coating, etc., but they all have certain defects. During the production and wearing of gloves, they will cause certain pollution to the surrounding environment. Harm to the human body. [0003] Solvent-based polyurethane coated gloves (polyurethane referred to as PU), in the solvent-based PU itself contains a large amount of highly toxic solvent dimethylformamide DMF, in the production process through hot water treatment, large Part of the DMF will be replaced, but there is still a small amount of ...
