Example Embodiment

[0037] The specific embodiment of the present invention provides a method for preparing graphene-nitrile latex frosted gloves, the method includes the following steps:

[0038] 1. Set the liner: put the glove liner on the hand mold.

[0039] 2. Impregnating coagulant: impregnate the glove liner with coagulant for 20-30s. The solvent of the coagulant is water, and the weight content of the solute and its weight in the solvent is 30-40wt% calcium nitrate, 0.1 -0.5wt% defoamer.

[0040] The role of the coagulant is to prevent penetration during subsequent dipping. When the glove liner is immersed in the coagulant, a water film will be formed on the surface of the glove liner. Adding 0.1-0.5wt% defoamer can eliminate the foam generated when the glove is immersed in the coagulant.

[0041] 3. Dipping: The glove liner is fully dipped in the graphene-nitrile rubber composite slurry, the latex viscosity is 600-700cp, the dipping time is 10-15s, the graphene-nitrile rubber composite slurry can...

[0053] The embodiment of the present invention discloses a preparation method of graphene-nitrile latex frosted gloves. The method includes the following steps:

[0054] S1. Set the liner: Put the glove liner on the hand mold.

[0055] S2. Impregnation coagulant: impregnate the glove liner with coagulant for 20s, the solvent of the coagulant is water, the solute and its weight content in the solvent are 30wt% calcium nitrate, 0.1wt% defoaming Agent.

[0056] S3. Dipping: Fully dipping the glove liner in the graphene-nitrile rubber composite slurry for 10-15 seconds. The graphene-nitrile rubber composite slurry can be prepared by the following method: Put one part of nitrile rubber into the stirring device, stir at a speed of 30r / min, add 60 parts by weight of plasticizer, 10 parts by weight of thickener, 7 parts by weight of emulsifier, 6 parts by weight of aqueous polyurethane, 15 parts by weight of crosslinking , 3 parts by weight of graphene, 300 parts by weigh...

Abstract

The invention relates to a preparation method of a graphene-butadiene-acrylonitrile rubber latex matting glove. The preparation method comprises, S1, arranging a glove liner on a hand mould in a covering mode; S2, impregnating the glove liner into curing agent for 20-30 s; S3, totally immersing the glove liner into graphene-butadiene-acrylonitrile composite slurry at a latex viscosity of 600-700 cp for 10-15 s; S4, performing salt spray treatment on the immersed glove liner; S5, performing primary drying inside a vulcanization crosslinking drying oven; S6, washing the dried glove; S4, performing secondary drying on the washed glove inside the oven; S8, performing cooling and demoulding to obtain the graphene-butadiene-acrylonitrile rubber latex matting glove. The prepared graphene-butadiene-acrylonitrile rubber latex matting glove is high in wearing resistance, puncture resistance, tear resistance and cutting resistance, highly antibacterial, capable of achieving far infrared radiationand the like.

Description

technical field [0001] The invention belongs to the technical field of rubber-dipped gloves, in particular to a preparation method of graphene-nitrile latex scrub gloves. Background technique [0002] After the surface of textile gloves, cloth sewing gloves, or leather gloves is impregnated with various natural rubber, synthetic rubber or synthetic resin, such as natural latex, nitrile rubber, PU resin, PVC resin, etc., a protective layer is formed on the surface of the gloves , so that the gloves have a non-slip effect. [0003] In order to enhance the anti-slip effect of the gloves, the gloves are usually soaked in a solvent, which corrodes and produces wrinkles, thereby achieving the anti-slip effect. However, the solvents used in the above method are chemical products such as xylene and acetic acid. During the production process, more irritating poisonous gases are produced, which not only causes certain damage to the environment, but also causes great harm to the healt...
