Abstract

The invention discloses a method for producing graphene functionalized nitrile flocked gloves. Highly-water-soluble graphene oxide is adopted, and is organically modified, the specially treated graphene oxide is uniformly dispersed in nitrile butadiene latex, a graphene oxide reducing agent is added into the latex, and the co-action of heat reduction of the graphene oxide and reduction of the reducing agent in the high-temperature vulcanization molding of the nitrile butadiene latex makes the performances of reduced graphene maximally shown in the latex gloves. Test data of the graphene functionalized nitrile flocked gloves show that the mechanical property tensile strength is improved by 65%, and reaches 43 MPa; the elongation at break is increased by 38% or above, and reaches 360% or above; the antibacterial performance reaches 100%, and the chemical resistance is grade 5; and the wear resistance, the cutting resistance and the puncture performance of the gloves are greatly improved.

Description

technical field [0001] The invention relates to a glove, in particular to a preparation method of a graphene functionalized nitrile flocked glove. Background technique [0002] Gloves are necessary protective products for people's daily life and industrial production. Among them, the long tube gloves produced with rubber and plastic as raw materials have good protective effects such as waterproof, anti-stain and anti-corrosion. However, gloves made of this material may suffer from skin allergies, bacterial infections, sweating, sticking, and odors during use, and the tear resistance and chemical resistance are not high, which cannot meet the requirements in chemical, petroleum, etc. industry use. In order to meet the needs of various industries for glove performance, it is urgent to develop a glove that can improve the above deficiencies and impart new properties such as antibacterial, mite removal, sweat absorption and deodorization. [0003] Investigating the patents of...
