The invention discloses a nano flame retardant plastic film and a preparation method thereof, comprising the following raw materials: high density polyethylene, modified flame retardant, plasticizer, magnesium oxide crystal, nano silicon dioxide, antibacterial agent and ultraviolet absorber , light stabilizer, dispersant and antioxidant, the present invention uses high-density polyethylene as the base material for preparing the nano flame-retardant plastic film, and improves its surface activity by grinding magnesium oxide whiskers and nano-silica during the preparation process, It can be quickly dispersed in high-density polyethylene to enhance the tensile strength of nano flame retardant plastic film. At the same time, the plasticizers are environmentally friendly and non-toxic. The main and auxiliary plasticizers are used together. Through the synergistic effect of the two, it can fully Wetting polyvinyl chloride and chlorinated polyethylene resins can well avoid their decomposition during processing, so that the raw materials have excellent cross-linking and plasticizing effects. By adding UV absorbers, light stabilizers and antioxidants It can effectively improve the durability and thermal stability of the nano flame retardant plastic film. |
