Problems solved by technology

[0004] However, the breaking strength and elongation at break of disposable nitrile gloves are respectively roughly 20MPa and 500%, which still cannot meet the performance requirements during normal use, and further improve the mechanical properties of disposable nitrile gloves, especially in terms of breaking strength and In terms of elongation at break, a disposable high-quality glove with high mechanical properties has been developed to meet the high-efficiency use in various fields
[0005] In addition, disposable nitrile gloves are mostly used in food, hygiene, medical treatment, etc., and are prone to breed a large number of bacteria when exposed to the air for a long time, and cannot essentially eliminate the use of bacteria under special application conditions. A long-lasting antimicrobial disposable high-quality glove

Description

technical field [0001] The invention relates to the technical field of latex gloves, in particular to a disposable graphene-nitrile rubber glove with antibacterial and antistatic functions and a preparation method thereof. Background technique [0002] Carboxylated nitrile rubber is formed by terpolymerization of butadiene, acrylonitrile and organic acid (acrylic acid, methacrylic acid, etc.). Abbreviated as XNBR, the relative density is 0.98-0.99. The introduction of carboxyl groups increases the polarity and imparts high strength, which has good adhesion and aging resistance, improves wear resistance and tear strength, and further improves oil resistance. The tensile strength is 25.5-26.5MPa, the elongation at break is 310%-380%, and the tear strength is 51.0-55.9kN / m. Nitrile gloves are made of nitrile material, titanium dioxide, auxiliary materials, and defoamers as the main raw materials through mixing, filtering, coagulation, drying and other processes. They have out...
