This invention discloses a method for preparing antibacterial packaging bags for grains, wherein the preparation method is as follows:
First, inorganic nano-calcium carbonate is placed in…120-140℃ preheating and drying.
Remove moisture after hours; then mix inorganic nano-calcium carbonate, titanate coupling agent, and anhydrous ethanol in a specific mass ratio.1:3:25Thoroughly mix and disperse, then process.
After minutes, the solvent was removed by vacuum drying to obtain organically modified nano-calcium carbonate;
First, copper sulfate and silane coupling agent are mixed according to…1:1Mixing, The product is dried at ℃ for modification.
The ingredients, including polyvinyl chloride resin, polyethylene resin, and other additives, are mixed in proportion and thoroughly blended using a high-speed mixer.
Granulation was performed on a twin-screw extruder at a temperature of ℃, followed by extrusion blow molding using a single-screw extruder.
Antibacterial packaging bags for grains are blow-molded at ℃.
