Abstract

The invention relates to graphene hydrogel modified latex, which comprises the following components in parts by weight: 100 parts of carboxylic butadiene-acrylonitrile rubber, 1-2 parts of potassium hydroxide, 1-1.5 parts of sulfur, 1.5-3 parts of zinc oxide, 0.5-1.2 parts of an accelerant, 0.01-0.03 part of a dispersing agent and 5-50 parts of graphene hydrogel. The preparation method of the graphene modified hydrogel rubber glove comprises the following steps: preparing graphene hydrogel modified latex, controlling the viscosity to be 3000-5000 mps, and performing standing treatment; preheating the glove core; dipping the glove core in a coagulator; dipping the glove core in graphene hydrogel modified latex; uniformly spreading salt on the glue surface for shaping the glove core; and pre-vulcanizing, soaking and washing, and vulcanizing the product. Compared with a traditional glove, the manufactured high-performance protective glove is more resistant to abrasion, tearing, electricity conduction and corrosion.

Description

technical field [0001] The invention belongs to the field of rubber impregnated gloves, in particular to a graphene hydrogel modified latex and a preparation method of graphene modified hydrogel rubber gloves. Background technique [0002] Graphene has many excellent properties, such as large specific surface area, high strength, and high electrical conductivity. Therefore, it is expected to be applied in various fields such as safety protection and electronic materials. However, the easy re-stacking between the sheets limits the industrial application. Graphite oxide is an important derivative of graphene, and graphene-based materials can be obtained through a reduction process. It has gel properties and can form graphene-based hydrogels under certain conditions. Its unique spatial structure can not only prevent sheet restacking, but also can be more conveniently applied to materials. Contents of the invention [0003] In order to solve the above problems, the present...
