Abstract

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.

Description

technical field The technology of the present invention relates to an environment-friendly and antibacterial polyvinyl chloride composite material and its preparation method, in particular to a kind of non-phthalic small molecule plasticizer, environment-friendly stabilizer and antibacterial agent and other new environment-friendly additives prepared by melt blending. The obtained environment-friendly polyvinyl chloride composite material with non-toxic and broad-spectrum antibacterial properties and a preparation method thereof. Background technique As one of the five general-purpose plastics, polyvinyl chloride (PVC) is widely used in the production of doors and windows, pipes, medical equipment, toys and other plastic products. 29% of total consumption. Polyvinyl chloride itself is a granular material with high mechanical hardness and easy to decompose when heated. In the production process of PVC, various additives such as plasticizers, stabilizers, and lubricants need ...
