Abstract: An antibacterial leather uses the organic silica gel as the main component, uses the carboxymethyl chitosan silver as the antibacterial factor, and uses the modified nano-silica and the modified layered double oxide as the flame retardant factor. The synergistic effects between the components, such as the good binding between carboxymethyl chitosan silver and the substrate, the synergistic flame retardant effect between flame retardant factors, the bonding effect between modified nano-silica and dimethicone, and the synergistic effect between the high-viscosity dimethicone and the low-viscosity dimethicone are utilized to improve the process, thereby obtaining a good antibacterial, flame retardant and other properties, meanwhile meeting the requirement for the material mechanical properties and environmental protection.
