White degradable plastic-coated wire and preparation method thereof

The invention relates to the technical field of plastic-coated wires, and discloses a white degradable plastic-coated wire and a preparation method thereof, the plastic-coated wire is composed of a metal wire in the middle, a plastic-coated layer on the outer side surface of the metal wire, and a chelating layer for combining the plastic-coated layer and the metal wire into a whole. The plastic coating layer is prepared from the following components in parts by weight: 60-99.8 parts of degradable plastic particles, 3-30 parts of titanium dioxide, 1-2 parts of an antistatic agent, 1-2 parts of an anti-weathering agent, 0-2 parts of a plastic production aid and 0-8 parts of a plastic functional aid. And the chelating layer comprises the following components in parts by weight: 0.5-1 part of a metal corrosive agent, 1-2 parts of a metal chelating agent and 0-1 part of a metal antirust agent. After the plastic-coated wire is used, the plastic-coated layer can be degraded, and the plastic-coated wire conforms to t
