Abstract

The invention discloses a medical high-molecular material and a preparation method thereof. The medical high-molecular material comprises the following components: polytetrafluoroethylene, a toughening agent, an antistatic agent, a lubricating agent, an antioxidant, calcium oxide, butyl rubber, polyethylene glycol laurate, methacrylic acid and dimethylethanolamine. The preparation method comprises the following steps: placing the components into a mixing stirrer, and uniformly stirring and mixing; then carrying out heating and thermal-insulation reaction in the presence of nitrogen; then reducing the temperature at the speed of 20 DEG C / minute; and finally extruding in a double-screw extruder. The medical high-molecular material provided by the invention is excellent in flexibility, transparency, impact resistance and antistatic resistant property and suitable for being widely used in the medical field.

Description

technical field [0001] The invention belongs to the field of medical materials, and in particular relates to a medical polymer material and a preparation method thereof. Background technique [0002] Polytetrafluoroethylene is known as the "King of Plastics". Roy Plunkett, the father of fluororesin, began to study the substitutes of Freon in the DuPont Company of the United States in 1936. They collected part of the tetrafluoroethylene and stored it in steel cylinders for the second time. The next day they carried out the next experiment, but when they opened the pressure reducing valve of the steel cylinder the next day, no gas escaped. They thought it was a gas leak, but when they weighed the cylinder, they found that the cylinder did not lose weight. They sawed open the cylinder and found a large amount of white powder, which was Teflon. They found that PTFE has excellent properties and can be used as anti-melt gaskets for atomic bombs and artillery shells. Therefore, th...
