Calcium-zinc soft alloy and preparation method of wire coated by calcium-zinc soft alloy

Abstract

The invention discloses an insulating material, calcium-zinc soft alloy, used as an electric automobile charging cable and a preparation method of a wire coated by the calcium-zinc soft alloy. The calcium-zinc soft alloy is prepared from the following components in percentage by weight: 40.0-45.0% of polyvinyl chloride resin, 4.0-5.0% of calcium carbonate, 5.0-6.0% of disilicon trioxide,1.0-2.0% of calcium stearate, 0.5-1.0% of zinc stearate, 1.0-1.5% of diantimony trioxide, 0.5-1.0% of polyethylene wax, 20.0-25.0% of triisooctyl phosphite,1.0-2.0% of 2-methyl ethyl ester, 1.0-2.0% of fatty glyceride, 1.0-2.0% of polydimethylsiloxane, 8.0-9.0% of acrylonitrile-butadiene, 1.0-1.5% of methyl styrene and 2.0-3.0% of chlorinated polyethylene. According to the wire prepared by coating with thecalcium-zinc soft alloy provided by the invention, when a cable with a diameter of 40mm or above is used, the cable can be bent and twisted to an any angle of 360 degrees, cracking does not occur, high wear resistance is achieved, and meanwhile high pressure resistance is achieved. The manufactured charging-gun cable is dragged on the ground for a long time, but the jacket of the cable cannot be worn out, so that the use is safe and convenient.

Description

technical field [0001] The invention relates to an insulating material, in particular to a safe and convenient insulating material for a high-voltage cable used for charging an electric vehicle and a preparation method for a coated wire thereof. This kind of cable can meet the requirements of flexibility and abrasion resistance for any torsional bending at the same time. Background technique [0002] Generally, high-voltage DC cables are fixedly connected between two points, and there is no need to move them after they are connected. Therefore, the entire cable is relatively hard and does not require wear resistance. However, the cable of the electric vehicle charging gun is not fixedly connected. When the electric vehicle is charged with the charging gun, the cable from the charging pile to the car charging interface is often dragged on the ground due to its high frequency of use, so it must require high wear resistance. It is also easy to use; and it is required to twist...
