Abstract

The invention relates to an active antibacterial and antiviral glove. The glove comprises, by mass, 80 to 95 parts of a rubber material, 0.8 to 5 parts of sodium hydroxide, 0.3 to 1.8 parts of sulfur,0.4 to 3.5 parts of nano-silver, 0 to 1.5 parts of zinc diethyldithiocarbamate, 0 to 1.0 part of zinc di-n-butyl dithiocarbamate, 0 to 1.5 parts of titanium dioxide, 0.1 to 1 part of an organic antibacterial and antiviral agent and 0.1-1 part of a natural antibacterial and antiviral agent. The rubber glove can achieve the long-acting antibacterial and antiviral effects of a latex glove, and the wearing comfort is not affected.

Description

technical field [0001] The invention relates to a glove, in particular to an active antibacterial and antiviral glove and a preparation method thereof. Background technique [0002] Gloves play the role of hand protection, and their antibacterial and antiviral effects directly affect the safety of gloves, especially medical gloves. In the prior art, antibacterial gloves are included in the ingredients of traditional rubber gloves and the appropriate production process stage - pre-vulcanization process stage, adding nano silver antibacterial agent, and making it evenly mixed in the rubber emulsion, rubber gloves are made by traditional production process to exert antibacterial or antibacterial effect. Adding nano-silver to the emulsion of rubber gloves, because the particle size of nano-silver is too small, it has a large specific surface area, is easy to agglomerate, is difficult to disperse, has poor compatibility with the glove matrix material, and is easy to dissolve. The...
