Insulating layer material for high-voltage electrical cabinet and preparation method thereof

Abstract

The invention discloses an insulating layer material for a high-voltage electrical cabinet. The material is prepared from the following raw materials in parts by weight: 8-24 parts of vinyl silicone rubber, 3-12 parts of chlorinated polyethylene rubber, 4-6 parts of ABS resin, 2-14 parts of decabromodiphenyl ethane, 5-15 parts of epoxy resin, 5-13 parts of stearic acid, 3-5 parts of cyanoacrylate, 2-4 parts of polyacrylate glue powder, 5-20 parts of a filler, 2-5 parts of a plasticizer, 1-6 parts of flame retardants and 0.5-1.5 parts of a stabilizer. A preparation method disclosed by the invention is simple and feasible, and the prepared insulating layer material can prevent the potential safety hazard that the insulating layer materials such as cables and electric wires are flammable in a high voltage environment. As flame retardants such as magnesium oxide, aluminum oxide and antimonous oxide are added into the raw materials, the insulating layer material has relatively high flame retardance and has the advantages of no toxicity, low smoke and the like.

Description

technical field [0001] The invention belongs to the field of electrical technology, and in particular relates to an insulating layer material for a high-voltage electrical cabinet and a preparation method thereof. Background technique [0002] At present, most of the insulation layer materials such as cables and wires in high-voltage distribution cabinets are made of flammable materials, while the insulation materials such as cables and wires in high-voltage electrical cabinets have been in a high-voltage environment for a long time, and their flame retardancy must be improved. Prevent or avoid the occurrence of fire, which will bring harm to the life and property of the country and the people. Commonly used flame retardant methods for insulating cable materials are halogen flame retardant, inorganic flame retardant and low-smoke halogen-free flame retardant. It brings difficulties and easily causes secondary pollution; the commonly used flame retardants for inorganic flame...

AI Technical Summary

Problems solved by technology

Commonly used flame retardant methods for insulating cable materials are halogen flame retardant, inorganic flame retardant and low-smoke halogen-free flame retardant. It brings difficulties and easily causes secondary pollution; the commonly used flame retardants for inorganic flame retardants are magnesium hydroxide and aluminum hydroxide, which have the advantages of low smoke and low toxicity, but their flame retardant effect is poor, and the water resistance of insulating cables is also poor. Poor, unable to meet the flame retardant requirements of current insulated cables
