Abstract

The invention belongs to the field of rubber materials, and particularly relates to a silver-plated graphene / synthetic rubber latex composition and a preparation method thereof. Silver is plated on the surface of modified graphene to obtain graphene coated with silver on the surface, and then the graphene coated with silver on the surfaceand synthetic rubber latex form the silver-plated graphene / synthetic rubber latex composition . The latex composition has antibacterial property and excellent mechanical property, and in addition, the preparation method provided by the invention has the advantages of simple equipment, simplicity in operation, good controllability, facilitation of industrial amplification and the like.

Description

Technical field [0001] The present invention belongs to the field of rubber technology, and more particularly to a silver plated graphene / synthetic rubber latex composition and a preparation method thereof. Background technique [0002] With the advancement of society, material life is increasing, and people's requirements are increasingly demanding. Rubber protective products common in daily life, such as medical gloves, condoms, protective gloves, etc., people hope that they can not only protect their own safety, but also block viruses, bacteria and other substances. However, rubber latex has a diameter of several hundred to several thousand nanometers, while the diameter of the bacteria is typically 0.5 microns, the thickness is 0.5 microns, and some viruses are smaller, the maximum diameter is several hundred or even tens of nanometers, these bacterial viruses will Spread through micropores, so how to further improve the protection of rubber latex products is one of the imp...
