Abstract

The invention discloses a high-voltage-resistant insulating tape. The tape is composed of a base layer and an adhesive layer. The adhesive layer is prepared from the following components by weight: 15-20 parts of polyimide, 10-12 parts of polytetrafluoroethylene, 20-25 parts of polyvinyl chloride, 2-5 parts of acetate, 30-35 parts of styrene-butadiene rubber, 40-45 parts of vinyl polyurethane rubber, 20-25 parts of an ethylene acrylic acid copolymer, 8-12 parts of pigment carbon black, 5-8 parts of zinc sulfate, 10-12 parts of quartz powder, 1-4 parts of anthracene oil, 3-7 parts of a plasticizer and 2-5 parts of an antioxidant. The invention has the advantages that the prepared insulating tape has high voltage resistance, good weather resistance and good flame retardancy, and is particularly applicable to high voltage conditions; the used raw materials are economical; the preparation method is simple in process and suitable for large-scale industrial production; and an isopropyl alcohol solution with a specific concentration is employed for cleaning the bonding surface of the base layer, so subsequent bonding process is more easily realized, a prepared composite layer is more compact, and the service life of the insulating tape is prolonged.

Description

technical field [0001] The invention belongs to the technical field of electrical protection materials, and in particular relates to a high-voltage-resistant insulating tape and a preparation method thereof. Background technique [0002] Insulating tape for electrical use refers to the tape used by electricians to prevent leakage and to insulate, also known as insulating tape and tape, consisting of a base layer and an adhesive layer. The base layer is generally made of cotton cloth, synthetic fiber fabric and plastic film, etc., and the adhesive layer is made of rubber plus tackifying resin and other compounding agents, with good viscosity and excellent insulation performance. Insulating tape has good insulation voltage resistance, weather resistance, flame retardant and other characteristics. It is suitable for wire connection and electrical insulation protection. [0003] However, with the sharp increase in electricity consumption, modern society has generally adopted ul...
