Abstract

The invention belongs to the field of plastic processing aids. The invention relates to a novel antibacterial antistatic additive for PE and a preparation method of the novel antibacterial antistaticadditive. The method comprises the following steps: with amino-dodecapolyethylene glycol-carboxylic acid (A), maleic anhydride (B), guanidine (C) and polyethylene as raw materials, performing multi-step amidation reaction; and performing blending extrusive blow-molding treatment to obtain a target product, namely the novel antibacterial and antistatic additive. The antistatic agent has certain flame-retardant and plasticizing effects while effectively overcoming the defects of durability and no bacterium resistance of the existing antistatic agent, structurally provides antibacterial and antistatic groups, reduces the consumption of a plasticizer, reduces electrostatic accumulation, improves the flame retardancy, prolongs the service life, enriches the application field, and is particularly suitable for food packaging films.

Description

technical field [0001] The invention relates to a novel antibacterial and antistatic additive for PE and a preparation method thereof. The invention belongs to the field of plastic processing aids. Background technique [0002] Due to its abundant raw material resources, moderate price, and superior product comprehensive performance, polyethylene (PE) has been widely used, especially in the packaging field. Since the polyethylene material has a non-polar molecular structure, the molecular chain composed of its covalent bonds can neither be ionized nor transfer free electrons. Once charged due to the gain and loss of electrons due to friction, it is difficult to eliminate. The static electricity generated by the PE material during the processing brings a lot of inconvenience to the further processing of the packaging film material, affects the operational performance of the product, and the printing effect is affected by the electrostatic interference when the film is used ...
