Abstract

The invention relates to a powder coating for a fire-proof electronic element. The powder coating mainly comprises the following main components: epoxy resin, silicon micropowder, a curing agent, fluorescent powder, a pigment, expanded vermiculite powder and organic silicon powder. The powder coating for the fire-proof electronic element, which is provided by the invention, is prepared through scientific proportion of raw materials and a reasonable preparation method; and the powder coating provided by the invention has the advantages of good fire resistance, abrasion resistance, impact resistance and adhesive force.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a powder coating for fireproof electronic components and a preparation method thereof. Background technique [0002] Powder coating is a dry solid powder that does not contain organic solvents. It is different from general solvent-based coatings and water-based coatings. It does not need solvents or water as a dispersion medium when coating, but uses air as a dispersion medium to spread evenly It is a new type of coating that is coated on the surface of the workpiece and forms a coating film after heating, which is significantly different from other coatings. Powder coating is a rapidly developing coating variety, which has the advantages of energy saving, environmental protection, and no three-waste pollution. It has been widely used at present, but some electronic components have high requirements for fire protection, and the powder coatings currently on the market cannot meet their req...
