preparation example Construction

[0022] A preparation method for preparing a medical high-strength PVC film according to claim 1, comprising the steps of:

[0023] a. Mixing, put the raw materials into the high-speed mixer according to the mass parts for mixing and stirring, the mixing time is 260~320 seconds, and the temperature is 80~90°C;

[0024] b. Cold mixing, transporting the mixed components in step a to a low-speed cold mixing machine, stirring and cooling, and controlling the cold mixing temperature to ≤55°C;

[0025] c. Extrusion. Send the cold-mixed mixture into a planetary extruder for extrusion. The extrusion temperature is controlled at 145~165°C. The output is bright and twist-like clinker;

[0026] d. Filtration. Send the rubber material from the extruder to the three-layer filter for filtration. After receiving the rubber material from the extruder, it will be conveyed into cylindrical clinker after passing through the three-layer filter of 80 mesh, 60 mesh, and 80 mesh. For rolling machine...

Abstract

The invention discloses a medical high-strength PVC film, which is prepared from the following raw materials in parts by weight: 100 parts of resin powder, 0.8 to 1.1 parts of food grade plasticizers,3.0 to 3.5 parts of food grade stabilizers, 1.5 to 1.7 parts of processing auxiliary agents, 6 to 7 parts of enhancing agents, 0.8 to 1 part of lubricating agents and 0.06 to 0.07 part of pigment ultramarine blue. The invention provides the medical high-strength PVC film with the advantages that the service life is long; the intensity is high; the wear-resistance performance is good; the waterproof performance is high. Meanwhile, the provided preparation method can realize the large-scale production.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a medical high-strength PVC film and a preparation method thereof. Background technique [0002] Medical workers are people who directly talk to bacteria and viruses. For some field medical workers or outdoor medical workers, conventional medical kits cannot meet their daily needs. Because the existing medical kits are made of cloth and It has poor strength and poor water resistance, and with the continuous improvement of the performance of existing new materials, many new materials are constantly being applied in new fields. If PVC film is used to prepare medical bags, how to prepare PVC film into It is a difficult problem to have antibacterial, corrosion resistance, high strength, and how to produce it on a large scale. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to make up for the deficiencies of the pri...
