Problems solved by technology

[0003] Commonly used antibacterial modified materials are silver ion antibacterial agents. Although silver ion antibacterial agents have good antibacterial effects, their prices are relatively high, and their antibacterial efficiency during use is relatively low.
Moreover, after metallic silver is dispersed into plastic materials, it is difficult to recycle later, which is a great waste of resources

Abstract

The invention relates to an anti-bacterial PVC material and a preparation method thereof. The anti-bacterial PVC material is prepared from, by weight, 100 parts of PVC, 2-5 parts of a stabilizer, 0.2-0.8 parts of a lubricant, 1-5 parts of a compatibilizer, 0.4-1.5 parts of a coupling agent, 2-8 parts of a plasticizer, 0.5-4 parts of an organic antibacterial agent and 8-25 parts of an inorganic antibacterial agent. In the design of the material, characters of the PVC material is fully considered, so that by means of the antibacterial plasticizer, with combination of the organic antibacterial agent and the inorganic antibacterial agent, mechanical performances of the PVC material is maintained and the antibacterial effect of the material is improved.

Description

technical field [0001] The invention belongs to the field of composite materials, and in particular relates to an antibacterial polyvinyl chloride material and a preparation method thereof. Background technique [0002] Polyvinyl chloride material is one of the most widely used general-purpose plastics. Polyvinyl chloride is polymerized by vinyl chloride under the action of an initiator, and the molecular weight of the polymer is generally between 50,000 and 120,000. Polyvinyl chloride material has good mechanical properties, good flame retardancy and dielectric properties. However, ordinary polyvinyl chloride materials lack high antibacterial properties. Therefore, there are certain performance defects when used in an environment with high antibacterial requirements. [0003] Commonly used antibacterial modified materials are added silver ion antibacterial agents. Although silver ion antibacterial agents have good antibacterial effects, their prices are relatively high, ...
