Abstract

The invention discloses an epoxy resin spray-coating method and a special-purpose epoxy resin spray-coating liquid thereof. The epoxy resin spray-coating liquid comprises, by weight, 100 parts of epoxy resin, 30 parts of a curing agent and 10-30 parts of xylene. The method comprises 1, spray-coating one side of a base, which is baked at a temperature of 110 DEG C for 15min and is to be spray-coated, with the epoxy resin spray-coating liquid, 2, baking the spray-coated base at a temperature of 100-120 DEG C for 15-30min, and 3, turning over the base baked through the step 2 and spray-coating the other side of the base through the steps 1 and 2. The epoxy resin spray-coating method accelerates amorphous nanometer crystal iron core package treatment time, reduces an amorphous nanometer crystal iron core package cost and improves performances of the amorphous nanometer crystal iron core spray-coated with epoxy resin.

Description

technical field [0001] The invention relates to an epoxy resin spraying method, in particular to a method for spraying epoxy resin on an amorphous nanocrystalline iron core. Background technique [0002] Small iron core packaging generally adopts two packaging methods: 1. Protective box packaging. This packaging method wastes manpower and raw materials, and the production cost is high, which increases the product price. Moreover, the introduction cost is high when reprocessing is performed. Generally speaking, this packaging method is not conducive to production. Second, spray packaging. Existing spraying packaging methods include spraying epoxy resin, spraying powder coating, etc. [0003] Existing epoxy resin spraying methods mostly adopt compressed air spraying. When this method is simply used to spray the amorphous and nanocrystalline iron core, the adhesion of the epoxy resin is weak, and the performance of the iron core after spraying is greatly reduced, and it is...
