The invention discloses a biological antistatic polymer polymer material, which relates to the technical field of polymer materials. Including an interlayer, the interlayer is a plasticized corn starch layer, and the two sides of the interlayer are respectively fixed and connected with a contact layer. The manufacturing method of the contact layer 2 is as follows: Step 1: After drying the polylactic acid in a drying box, separate the polylactic acid and the chain extender respectively. Place it in an internal mixer for mixing. The drying temperature of the drying box is between 75-80 °C, and the drying time is controlled at 4-5 hours. After a period of time, the material A is reached. The chain extender has a molecular weight of 60000-80000g/mol. of polystyrene/polyglycidylmethacrylate random copolymer, use 60-80g chain extender per kg of polylactic acid. In the present invention, antistatic fibers made of conductive polyacetylene, polyaniline, polypyrrole and polythiophene are interspersed in the contact layer, so as to avoid the charge storage caused by friction during the transportation and use of the material. to eliminate static electricity in materials. |
