Abstract
The invention discloses a method for preparing a PET (Polyethylene Terephthalate) acarus expelling high polymer material. The method comprises the following steps of: (1) grafting an ammonia low polymer (such as a low polymer of hexanediamine) with PET, and grafting with a guanidine salt (polyhexamethylene panoctine, hydrochloric acid polyhexamethylene guanidine and the like) to obtain antibacterial master batch; (2) dehumidifying the prepared antibacterial master batch; (3) weighing raw materials according to a formula, and uniformly stirring; and (4) granulating by using a double screw extruder to control the feeding speed for preventing the raw materials from being degraded. The method has the advantages that: the PET acarus expelling high polymer material prepared with the method has an efficient broad-spectrum antimicrobial and antivirus effect, a durable effect, high performance, excellent quality and reasonable price, is extremely safe to human bodies, and is easy to prepare.
