Problems solved by technology

[0003] However, the currently commercially available medical polyvinyl chloride materials tend to harden gradually at low temperatures, and will become brittle and yellow due to aging after long-term use, accompanied by the phenomenon of "blooming" in which plasticizers migrate to the surface

Abstract

The invention discloses a fluorinated hydrophobic anti-leakage medical bag material, which is composed of the following raw materials in parts by weight: fluorinated monomer 16-20, zirconium oxide 6-9, itaconic acid 1-2, sunflower Dioctyl dioic acid 3‑4, polyethylene glycol 1000 3‑4, lauryl dimethylamine oxide 0.5‑1, benzotriazole 0.7‑1, ammonium polyphosphate 3‑4, polyvinyl chloride 120‑ 140, butyl tin mercaptide 0.8-1, dicumyl peroxide 1-2, the present invention effectively improves the dispersion compatibility of zirconia in polyester, improves the stability strength of the finished product, the present invention adopts Fluorine-modified monomers can effectively improve the hydrophobicity of finished materials.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a fluorinated hydrophobic anti-leakage medical bag material and a preparation method thereof. Background technique [0002] Medical polyvinyl chloride is a thermoplastic resin polymerized by vinyl chloride under the action of an initiator. The average degree of polymerization is 5001-14001. It is insoluble in water but soluble in organic solvents such as cyclohexanone and tetrahydrofuran. The heat resistance is not high, generally it should be used below 70°C. Medical polyvinyl chloride requires its products to be slightly yellow, transparent, soft, and have certain anticoagulation and flexibility. It is mainly used for blood transfusion, infusion bags, catheters for extracorporeal circulation devices, bubbling oxygenation bags, urine bags, etc. Products for short-term human exposure. [0003] However, currently commercially available medical polyvinyl chloride materials t...
