Abstract

The invention belongs to the field of building materials, and particularly relates to a layered anti-static PVC coiled material and a preparation method thereof. The coiled material is composed of a first functional layer, a first PVC layer, a second functional layer and a second PVC layer from bottom to top. The preparation method comprises the steps that lignin, copper nanowires, activated carbon and porous polylactic acid fibers serve as raw materials, are mixed and then are loaded with chitosan and MgO to prepare the first functional layer; preparing the first PVC layer by taking substances such as PVC resin, hydroxyapatite, carbon black and trioctyl citrate as raw materials; loading TiO2 and ZnO by taking carbon nanotubes, carbon black, conductive carbon nanowires and polylysine as raw materials to obtain the second functional layer; preparing the second PVC layer by taking PVC resin, carbon black, epoxidized soybean oil and the like as raw materials; and performing hot pressing to obtain the PVC coiled material. The PVC coiled material is free from arching and foaming and good in aging resistance.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a layered antistatic PVC coiled material and a preparation method thereof. Background technique [0002] Static electricity is a kind of charge in a static state; static electricity in nature mainly includes four electrification methods: contact separation electrification, friction electrification, flowing current and induction electrification. After the static electricity is formed, due to the difference in the resistivity of the object, the accumulation of static electricity is also different. In materials with poor conductivity, the transfer of electrons is difficult, and the static electricity is not easy to dissipate, resulting in the accumulation of static electricity. [0003] The harm of static electricity is reflected in many aspects: firstly, due to the interaction of charged bodies, the static electricity generated on the aircraft body will interfere with ...
