Epoxy resin-enhanced laminated insulating profile and preparation method thereof

Abstract

The invention discloses an epoxy resin-enhanced laminated insulating profile. The epoxy resin-enhanced laminated insulating profile comprises modification polymers and a reinforcing material, wherein the modification polymers include epoxy resin, a curing agent, a promoting agent, a flame retardant, a wetting dispersant and a solvent; the reinforcing material is a fiber material; the components of the modification polymers are mixed to form a modification polymer solution, the reinforcing material is soaked into the modification polymer solution and is finally subjected to hot press molding to form the epoxy resin-enhanced laminated insulating profile. The epoxy resin-enhanced laminated insulating profile is integrated with lightness, flame retardance, corrosion resistance and insulativity, has extremely high mechanical property, excellent electrical insulation property and halogen-free flame retardance, is environmentally friendly, is high in use safety and can be applied to industries and fields including State Grid Corporation of China, new energy resources, energy conservation, consumption reduction and track traffic which have high requirements to material performance and special working conditions and environments.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to an epoxy resin reinforced laminated insulating profile and a preparation process thereof. Background technique [0002] Epoxy resin laminated insulating profiles refer to impregnating flame-retardant epoxy resin solution with non-alkali glass cloth, non-alkali glass fiber felt, special glass cloth / fiber, etc., after baking, cutting, laying, and laminating in a special mold. The various shapes (L-shaped, U-shaped, Ω-shaped) profiles formed by hot pressing, their mechanical properties can be compared with some metal materials, and have the advantages that metals cannot match, with light weight, high mechanical strength and electrical insulation properties , for high-voltage electrical, power electronic equipment / devices (high-voltage inverters, high-voltage soft-start cabinets, wind power converters, SVG dynamic reactive power compensation devices for wind power grid co...
