Environmentally-friendly antibacterial polyvinyl chloride composite material and preparation method thereof

The invention relates to an environmentally-friendly antibacterial polyvinyl chloride composite material and a preparation method thereof. The composite material consists of the following components in part by weight: 100 parts of polyvinyl chloride, 20 to 60 parts of non-o-benzene small molecular plasticizer, 3 to 20 parts of processing modifier, 1 to 10 parts of non-toxic stabilizer, 0.5 to 5 parts of lubricant and 0.5 to 3 parts of inorganic silver antibacterial agent; and the composite material is obtained by melting and blending the components. The polyvinyl chloride material prepared by the method is non-toxic and environmentally-friendly, has broad-spectrum antibacterial property, and is used in the fields of building, food packing, medical instruments and the like.
