Abstract

The invention relates to the technical field of preparation of high polymer materials, and particularly discloses a degradable antibacterial material for medical treatment and public health and a preparation method thereof. The degradable antibacterial material for medical treatment and public health comprises the following raw material components in parts by weight: 50-80 parts of polylactic acid, 30-50 parts of poly(butylene adipate / terephthalate), 30-50 parts of starch, 0.5-2 parts of an antibacterial agent, 1-3 parts of antibacterial essential oil, 1-3 parts of a lubricant, and 1-10 parts of a dispersant. The invention provides the degradable antibacterial material for medical treatment and public health and with a brand new composition; the antibacterial agent triclosan and the antibacterial essential oil are added into the material, so that the material can play an antibacterial role in medical use and can be automatically degraded when being discarded.

Description

technical field [0001] The invention relates to the technical field of polymer material preparation, in particular to a degradable antibacterial material for medical and sanitation and a preparation method thereof. Background technique [0002] Medical and sanitary materials refer to consumable auxiliary products used by medical and health institutions in medical treatment, prevention, health care and other related activities, as well as packaging materials for various medical products. Whether medical and sanitary materials can be degraded after being discarded is one of the current research directions of medical and sanitary materials. [0003] Polylactic acid (PLA), polybutylene adipate / terephthalate (PBAT) and starch are commonly used degradable raw materials; at present, there are also many reports of using these three raw materials for melt blending to prepare degradable materials . However, at present, the degradable materials prepared from polylactic acid (PLA), po...
