Abstract

The invention discloses a thermoplastic nylon composite insulating material and a preparation method thereof, wherein the composite insulating material comprises nanometer montmorillonite and the following components by weight: 30-60 parts of a nylon 66 resin, 30-60 parts of glass fiber, 0.2-2.0 parts of an antioxidant, and 3-7 parts of a toughening agent, wherein the nanometer montmorillonite accounts for 2-7% of the mass of the composite material, and the toughening agent is any one or a combination selected from a styrene-butadiene-styrene block copolymer, a styrene-ethylene-hydrogenated butadiene-styrene block copolymer, an ethylene-vinyl acetate copolymer and an ethylene-acrylic acid copolymer. According to the present invention, the thermoplastic nylon composite insulating material has low density, such that the insulating member prepared from the thermoplastic nylon composite insulating material is small and light; and the thermoplastic nylon composite insulating material has advantages of excellent mechanical properties, excellent heat resistance and excellent electrical insulation property, is suitable for the manufacturing of medium-voltage electric apparatus insulating members, is a thermoplastic plastic, can be recycled, and further has good economic and environmental benefits.

Description

technical field [0001] The invention belongs to the technical field of insulating materials for medium and high voltage electrical appliances, in particular to a thermoplastic nylon composite insulating material, and also to a preparation method of the thermoplastic nylon composite insulating material. Background technique [0002] Insulating materials for electrical equipment are materials that isolate charged parts from other parts in electrical equipment, or isolate charged parts with different potentials and prevent the passage of current. Therefore, the insulating material should firstly have high insulation resistance and compressive strength, and be able to avoid accidents such as leakage and breakdown; secondly, the heat resistance should be good to avoid aging and deterioration due to long-term overheating; in addition, it should also have good thermal conductivity , Moisture resistance and lightning protection, high mechanical strength and convenient processing. ...
