Abstract

The invention discloses a stable weather-resistant high-insulating-property enamel wire coating and a preparation method thereof. The coating includes, by weight, 40-50 parts of compound resin, 8-10 parts of a nano-modifying additive, 4-6 parts of organic glass powder, 3-5 parts of hydroxyapatite nano-particles, 9-13 parts of a processing aid, 6-8 parts of a silane coupling agent, 28-34 parts of organic solvent, 7-11 parts of a flame retardant, 4-6 parts of an ester additive, and 9-11 parts of auxiliary filler. The enamel wire coating is quick to dry, has great leveling property, is great in high temperature resistance, is acid and alkali resistant, has stable performance, is low in water absorption rate, and has excellent mechanical and insulation performances, is high in inflection pointtemperature on a dielectric loss curve, has excellent indices of dissolvability, precipitation and liquid viscosity, is low in raw material cost, has definite preparation process and convenient use method, and has great practical value and application prospect.

Description

technical field [0001] The invention relates to the technical field of enameled wire materials, in particular to an enameled wire varnish with stable weather resistance and high insulation performance and a preparation method thereof. Background technique [0002] Enameled wire is the most representative product among electronic wires. Enameled wire is a main variety of winding wire, including the core wire and the paint layer coated on the outside of the core wire. After the bare wire is annealed and softened, it is painted and baked many times. It has four major properties: mechanical properties, chemical properties, electrical properties, and thermal properties. Copper-clad aluminum enameled wire and copper-clad aluminum-magnesium enameled wire are new electromagnetic wires that use copper-clad aluminum or copper-clad aluminum-magnesium material as the inner conductor. Its characteristics are between copper and aluminum, combining the excellent conductivity of copper and ...
