Embodiment 1

[0035] A transparent medical antibacterial polyvinyl chloride material of the present invention comprises 100 parts by weight of a polyvinyl chloride resin with a weight average molecular weight of 3.5, 1.2 parts by weight of an antibacterial agent, 3.0 parts by weight of a hindered amine light stabilizer, 1.7 parts by weight of The calcium-zinc composite stabilizer is added in the mixer, the blade speed of the mixer is 1000rpm, and it is mixed uniformly at a temperature of 40°C, and then 40 parts by weight of plasticizer is added, and the mixture is continued at 75°C, and then the obtained The mixture was melted and kneaded at 120°C, using a single-screw extruder with a screw speed of 40rpm, a feed temperature of 80°C, plastic melting at 130°C, and a discharge temperature of 150°C.

Embodiment 2

[0037] A kind of transparent medical antibacterial polyvinyl chloride material, every polyvinyl chloride resin that the weight average molecular weight that comprises 100 weight parts as base resin is 4.5 just comprises following component:

[0038] A) 1.5 parts by weight of antibacterial agent;

[0039] B) 50 parts by weight of plasticizer;

[0040] C1) 3.5 parts by weight of hindered amine light stabilizer;

[0041] C2) 2.2 parts by weight of calcium-zinc composite stabilizer.

[0042] Add polyvinyl chloride resin and other components except component B into the mixer, and mix uniformly at a temperature of 50°C; then add component B and continue mixing uniformly, at 90°C; Melt kneading at 150°C, plasticize, extrude, and finally granulate. The blade speed of the mixer can be controlled to 1100rpm, the granulation twin-screw extruder, the screw speed is about 40rpm, the feed temperature of the screw is 90°C, the temperature of the plasticizing and melting section is 150°C, ...

Abstract

The invention relates to a transparent medical antibacterial polyvinyl chloride material and a preparing method thereof. The material comprises 100 weight parts of polyvinyl chloride resin serving as basic resin, an antibacterial agent, plasticizer and optional stabilizer. The antibacterial agent is directly added into the carrier material, by means of a blending method, the antibacterial agent is directly added into the carrier material, and the raw material obtains an antibacterial property. The polyvinyl chloride material has the greatest advantage of being easy to process and capable of ensuring durability, as the new antibacterial agent on the inner layer can be exposed even if the material surface is abraded, the antibacterial agent cannot be transferred, and the transparent medical antibacterial polyvinyl chloride material is particularly suitable for serving as a medical macromolecular material.

Description

technical field [0001] The invention belongs to the field of biomedical polymer materials, in particular to a polyvinyl chloride material, in particular to a transparent medical antibacterial polyvinyl chloride material and a preparation method thereof. Background technique [0002] "Antibacterial" refers to inhibiting the growth, reproduction and survival of microorganisms such as bacteria and fungi within a certain period of time; "antibacterial agents" generally refer to substances that can be added to materials to endow them with antibacterial properties; the preparation of "antibacterial materials" is usually Add antibacterial agents directly to materials, or introduce antibacterial groups into materials in other ways to make them antibacterial. Sometimes, antibacterial agents themselves can be used as antibacterial materials. [0003] The spread and spread of harmful bacteria is a serious threat to human health, and people have to face the infestation of microorganisms...
