Alcohol acid type wire enamel for electric reactor and application thereof

Abstract

The invention provides alcohol acid type wire enamel for an electric reactor. The alcohol acid type wire enamel is prepared from the following raw materials in parts by weight: 28 to 32 parts of phthalate anhydride, 12 to 14 parts of trimellitic anhydride, 22 to 25 parts of pentaerythritol, 14 to 18 parts of ethylene glycol, 5 to 10 parts of acetic acid, 6 to 9 parts of glycerol, 18 to 25 parts of dodecanedioic acid, 5 to 7 parts of iron oxide red, 10 to 13 parts of titanium pigment, 3 to 6 parts of zinc naphthenate, 5 to 9 parts of silicone oil, 10 to 15 parts of dimethylbenzene, 10 to 15 parts of 200# solvent naphtha and 5 to 8 parts of auxiliary. The alcohol acid type wire enamel for the electric reactor, which is provided by the invention, compared with wire enamel in the prior, is decreased by 34 percent in water absorption, has obvious hydrophobicity and moisture resistance, has the temperature classification which is not less than 170 DEG C, is high in paint film bonding strength and good in adhesive force, and when being applied to the electric reactor, can be used for effectively improving the safety and the reliability of electric equipment of the electric reactor and the like.

Description

technical field [0001] The invention relates to a wire enamel, in particular to an alkyd type wire enamel for a reactor and its production and application. Background technique [0002] Enameled wire varnish is one of the core components of the insulating material for reactors. It can make a good insulating coating between the wires in the reactor and the wires. It is mainly used for the outer layer of metal coils with various wire diameters. Improve and stabilize the performance of enameled wire. Under the action of high temperature, electric field and magnetic field for a long time, the enameled wire varnish will gradually lose its original adhesion and insulation properties, such as becoming brittle, weakening of mechanical strength, electrical breakdown, etc. When the load and the surrounding environment act, the sum, intensity and duration of these loads will reduce the safety and reliability of the reactor. [0003] Existing wire enamel generally has problems such as...
