The invention belongs to the technical field of medical protective clothing, in particular to a PTFE isolation film for medical protective clothing and a preparation method thereof. In parts by mass, it is composed of the following raw materials: 100 parts of PTFE dispersing resin, 20-40 parts of pore-forming agent, 0.5-1.0 part of antibacterial agent, 0.08-0.1 part of dispersant, 0.7-1.0 part of fluorine-containing waterproof and oil-repellent agent, Antistatic agent 0.5‑0.8 phr. The medical protective clothing PTFE isolation film of the present invention is a medical multi-functional protective clothing developed by using a polytetrafluoroethylene composite film as the isolation layer, and has durable waterproof, water repellent, antibacterial, antistatic, flame retardant, moisture permeability and other physical properties. Mechanical properties, it has good barrier properties for blood and viruses (heavy liquid or gas) under natural conditions and pressure conditions, and the barrier (filtration) efficiency is greater than 99%. |
