Problems solved by technology

The layered structure inorganic materials used in these patents can be used in an unmodified or modified state. In the modified state, quaternary ammonium salts or quaternary phosphonium salts of different structures are used for interlayer modification. However, after the layered structure inorganic additives using quaternary ammonium salts as intercalation agents are added to the resin, the quaternary ammonium salts will cause incomplete resin bridging during the post-baking and hardening process, which will cause the enameled wire insulation film to be brittle. crack

Abstract

The invention relates to a surge-withstanding insulating paint with flexibility and attrition resistance, which comprises the following components: 12-76wt% of synthetic resin, 20-80wt% of organic solvent, 0.005-16wt% of polyethylene oxide (PEO) intercalation modified laminated clay material and 0.995-16wt% of organic dispersible nano silicon oxide particle. Since the paint contains the clay with high dielectric constant and superior attrition resistance and the nano silicon oxide particles, the insulating film formed by the paint can generate a capacitor-like effect, thereby absorbing and uniformly dispersing surges, and preventing damages caused by the surges; the insulating film also has fine attrition resistance; and since the PEO structure is soft and flexible, the insulating film for enamel wires has better softness.

Description

technical field [0001] The invention relates to an insulating coating, in particular to an insulating coating used as an insulating layer coated on the surface of a metal wire of an enameled wire. Background technique [0002] After experiencing the secondary energy crisis and excessive carbon dioxide emissions that caused serious damage and warming to the global environment, all advanced countries in the world have paid considerable attention to energy conservation and environmental protection, and formulated various industrial policies to control energy waste and environmental pollution. Promote environmental protection measures. Among them, in terms of power utilization, inverters with energy-saving effects have attracted much attention because of the vigorous promotion of environmental protection policies by governments of various countries. The frequency converter can change the voltage and frequency to control the speed of the motor. Due to its variable speed, in addi...
