Problems solved by technology

The surface coating of thermoplastic composite panels such as PVC and PVC composite panels is a UV coating. The performance of this layer of UV coating determines the main functions of thermoplastic composite panels such as PVC and PVC composite panels. Existing PVC and PVC composite panels The UV coating used in thermoplastic composite panels such as boards only has a certain degree of transparency and wear resistance, and cannot meet the diverse needs of thermoplastic composite panels such as PVC floors and composite panels.

Abstract

The invention discloses a carbon nanotube/TiO2 modified UV resin coating with antistatic and antibacterial functions. The carbon nanotube/TiO2 modified UV resin coating with antistatic and antibacterial functions is formed through compounding UV resin with a photoinitiator, an active diluent and various assistants; the resin is epoxy acrylic resin; and carbon nanotubes (CNTs) with the surface being grafted with methyl methacrylate (MMA) and nano-TiO2 with the surface being hydrophobically modified are added to the UV coating. The invention also discloses a production method of the carbon nanotube/TiO2 modified UV resin coating with antistatic and antibacterial functions. The method comprises the following steps: 1, purifying the CNTs, and grafting the surface of the CNTs with the MMA; 2, hydrophobically modifying the surface of the nano-TiO2; and 3, modifying an epoxy acrylic resin coating with the CNTs with the surface being grafted with the MMA and the nano-TiO2 with the surface being hydrophobically modified. The carbon nanotube/TiO2 modified UV resin coating has good antistatic and antibacterial functions.
