Graphene laminated rubber glove and preparation method thereof

Abstract

The invention relates to a graphene laminated rubber glove which comprises a glove blank, a rubber layer and a graphene membrane layer, wherein the rubber layer is adhered to the outer surface of theglove blank; the graphene membrane layer covers the outer surface of the rubber layer; the rubber layer is made of graphene-free foamed rubber or non-foamed rubber. A preparation method of the glove comprises the following steps: preparing graphene-free rubber slurry, and soaking a knitted glove blank into the rubber slurry; preparing a graphene-latex dispersion, and further soaking the glove blank soaked into the rubber slurry into the graphene-latex dispersion; performing vulcanization drying, thereby obtaining the graphene laminated rubber glove. Due to secondary soaking, the rubber slurryof primary soaking is cured to form a rubber body structure part of the glove, and then the quality of the main body structure can meet related standards (EN388) and ensure basic working protection functions of gloves; due to secondary soaking, a graphene laminated membrane can be formed, so that a rubber surface formed by primary soaking can be protected, and various overall properties of a gloveproduct can be improved.

Description

technical field [0001] The invention relates to a preparation method of gloves, in particular to a graphene-coated rubber glove and a preparation method thereof. Background technique [0002] As a single atomic layer material, graphene is the thinnest two-dimensional material found so far, its theoretical thickness is only 0.35nm, and graphene has a large specific surface area of ​​2600m 2 / g and elastic modulus of 1000Gpa, often used in physics, materials, electronic information, computers and other fields. The modulus of elasticity is an index to measure the difficulty of elastic deformation of the material. The larger the value, the greater the stiffness of the material. Graphene is added to rubber to increase the friction resistance, high strength, antibacterial properties of rubber products, improve the mechanical strength of rubber and many other functions. But there are not many existing technologies for applying it to rubber gloves at present, and the technology is...

Problems solved by technology

Such a high-viscosity mucilage is not only difficult to add various compounding agents (even if added, the dispersion uniformity is very poor), but also a series of quality problems caused by too high viscosity, such as the extremely poor wetting ability of the mucilage, Glove embryos are difficult to dip and evenly glue. After drying, the gloves will have quality problems such as glue peeling and webbing between fingers.

To add graphene and to control the viscosity, either the amount of graphene added is controlled below 0.1%, so that the overall performance of the glove is not significantly improved; or the latex surface tension is reduced by adding synergists (such as Span, Tween, etc.) Multi-graphene dissolves into the slurry, and the addition of synergists is also easy to cause problems such as glue penetration and cracking

[0004] Tracing it to its cause, mainly lies in: (1) graphene specific surface area is very big, and only has solubility in non-polar solvent, therefore adds in the inside of l...
