Abstract

The invention relates to a medical multifunctional polyvinyl chloride composite material which consists of polyvinyl chloride (PVC) resin powder, a nano modified material, a plasticizer, a stabilizer and a lubricant. In the formula, every 100 portions of PVC resin powder is added with 0.5 portion to 3 portions of nano modified material, 20 portions to 40 portions of phthalic acid ester, 10 portions to 30 portions of trimellitate, 10 portions to 30 portions of citrate, 5 portions to 10 portions of epoxidized soybean oil (ESO), 0.5 portion to 1 portion of calcium stearate (CaSt), 0.5 portion to1 portion of zinc stearate (ZnSt) and 0.1 portion to 0.5 portion of silicon oil according to portions by weight. The nano modified material is nano silver-supported zinc oxide or nano silver-supportedtitanium dioxide and has the main effects of having anti-bacterial function and being capable of improving the physical properties of resins. The composite material has reasonable formula, stable performance, simple technology, nano antibacterial function and low dissolution performance of the plasticizer, and can be used for producing various medical apparatuses.

Description

technical field [0001] The invention relates to a polymer material, in particular to a medical multifunctional polyvinyl chloride (PVC) composite material, which is used in the production of medical equipment and has antibacterial properties, low dissolution and high elasticity. Background technique [0002] We know that polyvinyl chloride (PVC) is cheap and has excellent comprehensive physical and mechanical properties. It is widely used as a raw material for the production of disposable infusion sets and blood transfusion sets at home and abroad. With the extensive and in-depth clinical application and the development of related medical science and technology, people found that PVC material itself has potential safety hazards, and there are various deficiencies in processing and use performance. For example, because polyvinyl chloride plastic itself is relatively hard, it is not suitable for infusion set components such as catheters and drip funnels, so a large amount of p...
