Embodiment 1
[0016] A mildew-resistant and antibacterial packaging bag material, the raw materials of which include by weight: 80 parts of polypropylene, 5 parts of organic phosphorus-containing anti-fungal agent, 1 part of eucalyptus oil, 2 parts of chitin, 4 parts of nano-titanium dioxide, and 1 part of silane coupling agent part, 0.5 part of phosphite lipid stabilizer.
[0017] The organic phosphorus-containing antifungal agent is prepared by the following process: Weigh the alkyl primary amine, alkyl hypophosphorous acid, cyanamide, N-hydroxyethylethylenediamine respectively in a molar ratio of 5:7:5:2, and the alkyl Add primary amine and alkyl hypophosphorous acid to ethanol, raise the temperature to 60°C and stir for 2 hours, then add cyanamide solution, after continuing the reaction, remove ethanol and dry to obtain prefabricated material; mix prefabricated material with N-hydroxyethylethylenediamine After heating to reflux for 4 hours, an organic phosphorus-containing antifungal ag...
Embodiment 2
[0019] A mildew-proof and anti-bacterial packaging bag material, the raw materials of which include by weight: 100 parts of polypropylene, 15 parts of organic phosphorus-containing anti-mold agent, 2 parts of clove oil, 1 part of chitosan, 10 parts of nano zirconium phosphate, aluminate 3 parts of quasi-coupling agent, 2 parts of rare earth stabilizer.
[0020] The organic phosphorus-containing antifungal agent is prepared by the following process: Weigh the alkyl primary amine, alkyl hypophosphorous acid, cyanamide, N-hydroxyethyl ethylenediamine respectively in a molar ratio of 6:8:6:3, and the alkyl Add primary amine and alkyl hypophosphorous acid into ethanol, raise the temperature to 70°C and stir for 3 hours, then add cyanamide solution, after continuing the reaction, remove ethanol and dry to obtain prefabricated material; mix prefabricated material with N-hydroxyethylethylenediamine After heating to reflux for 6 hours, an organic phosphorus-containing antifungal agent ...
Embodiment 3
[0022] A mildew-proof and anti-bacterial packaging bag material, the raw materials of which include by weight: 90 parts of polypropylene, 20 parts of organic phosphorus-containing anti-mold agent, 2 parts of eucalyptus oil, 1 part of chitosan, 3 parts of nano-titanium dioxide, and 4 parts of nano-zirconium phosphate 2 parts, 2 parts of silane coupling agent, 1.5 parts of phosphite stabilizer or rare earth stabilizer.
[0023] The organic phosphorus-containing antifungal agent is prepared by the following process: Weigh the alkyl primary amine, alkyl hypophosphorous acid, cyanamide, and N-hydroxyethylethylenediamine in a molar ratio of 5:8:5:3. Add primary amine and alkyl hypophosphorous acid into ethanol, raise the temperature to 65°C and stir for 2.5 hours, then add cyanamide solution, after continuing the reaction, remove ethanol and dry to obtain the preform; mix the preform with N-hydroxyethylethylene di After the amine is heated and refluxed for 5 hours, the organic phosp...
