A kind of breakdown-resistant insulating composite material and preparation method thereof

Abstract

The invention discloses an anti-breakdown insulating composite material which is prepared from the following materials in parts by weight: unsaturated polyester resins, polyimide resins, silicone insulation resins, sericite, naphthalene heterocyclic resins, polyethylene glycol terephthalate, polyethylene, butadiene rubber, unsaturated polyester, polyorganosiloxane resins, titanate, disulfide ether, phosphite ester, phosphoric acid triallyl ester and dicyandiamide. The insulating composite material is prepared by adopting high polymer materials, so that the composite material has excellent heatresistance and ultra-high mechanical property; the sericite and polyethylene are capable of improving the breakdown resistance; by coordination of the phosphoric acid triallyl ester and dicyandiamide, the flame-retardant property of the prepared insulating composite material is improved; the disulfide ether is capable of effectively capturing oxygen free radicals or peroxylradicals, and then thephosphite ester is capable of supplying hydrogen atoms, so that the disulfide ether is regenerated and maintains long-term antioxidant effectiveness. The polyorganosiloxane resins have ultra-high hydrophobic property, so that the prepared insulating composite material can be prevented from being eroded by water, and the service life of the composite material is prolonged.

Description

technical field [0001] The invention specifically relates to a breakdown-resistant insulating composite material and a preparation method thereof. Background technique [0002] Insulating materials are the basis and guarantee for the development of electrical products, and play a particularly important role in the development of motors and electrical industries. The development and progress of insulating materials depends on the development of polymer materials and directly restricts and affects the development and progress of electrical products. . Insulating materials are also the key to the advanced technology of electrical products and an important guarantee for the long-term safe and reliable operation of electrical products. Therefore, it is required to continuously develop new varieties of insulating materials and improve product performance and quality to meet the needs of continuous development of electrical products. At present, the insulating composite materials...

AI Technical Summary

Problems solved by technology

At present, the insulating composite materials on the market are either not highly insulating, or not strong in corrosion resistance, or have a short service life. However, as the functions of electrical products become more and more powerful, the requirements for insulating composite materials are also increasing. Our Insulation composite materials not only need to have high insulation, but also have good breakdown resistance, heat resistance, mechanical strength, hydrophobicity and anti-aging. The current insulation composite materials on the market can no longer meet the needs of electrical products.
