Abstract

This present invention discloses a temperature-sensitive nano-silver controlled release antibacterial coating composite, which is comprises: water, acrylic, polyurethane resin, temperature-sensitive nano-silver controlled release antibacterial agent, dispersant, curing agent, defoamer, filming additive and leveling agent. By adsorbing nano silver particles into the pores of mesoporous SiOmodified by poly N-isopropyl acrylamide, we successfully prepared a temperature-sensitive nano-silver controlled release antibacterial agent. By adding the prepared agent to the conventional coating composite, we achieved 'on-off' control of the antibacterial properties of coating composite. Through the control of temperature, the release of nano-silver in the mesoporous nano-silica of the coating film layer is controlled. This control method is not only to protect the nano-silver, but also to adjust the strength of the anti-bacterial properties according to the actual demands and improve the use-efficiency of nano silver particles. This invention is in line with the new concept of 'Intelligent Age' in the 21st century.
