Abstract

The present invention relates to an insulation electrical engineering bushing plastic and a preparation method thereof. The plastic comprises the following components, by mass, 70-90 parts of a PVC resin, 10-17 parts of an acrylonitrile-butadiene-styrene copolymer, 30-45 parts of dioctyl phthalate, 3-8 parts of dioctyl adipate, 0.5-3 parts of epoxy soybean oil, 1-4.5 parts of calcined kaolin, 1.5-2.7 parts of dibasic lead phosphite, 1.2-1.8 parts of fatty acid ester, 5-10 parts of aluminum hydroxide, 2-5 parts of zinc borate, 1.5-3 parts of barium stearate, 1-3.5 parts of an organotin stabilizer, and 1.5-4 parts of PE wax. The insulation electrical engineering bushing plastic has characteristics of high strength, high impact resistance, high toughness, good insulation and good fire retardation, and can provide good protection effects for electric wires, electric cables and the like.

Description

technical field [0001] The invention relates to a plastic and a preparation method thereof, in particular to a plastic for insulating electrical bushings and a preparation method thereof. Background technique [0002] In the electrical bushing industry, compared with traditional metal bushings, plastic bushings have the advantages of light weight, good insulation performance, good corrosion resistance, and long life. convenient. At present, the material used to make plastic sleeves is generally PVC resin, which is relatively cheap, has excellent mechanical properties, and is easy to process, making it the most widely used material in the wire and cable industry for a long time. [0003] Existing plastic sleeves still have insufficient insulation properties, and are not flame-retardant and impact-resistant, and tend to become brittle and break after a long time of use, so that wires and cables cannot be well protected. Contents of the invention [0004] Technical problem ...
