Problems solved by technology

[0006] The technical problem to be solved by the present invention is: for the concentrated sulfuric acid in the method of oxidation of concentrated sulfuric acid to form an insulating film to produce electromagnetic wire pollutes the production environment and causes human health hazards and the problem of water pollution caused by discharged waste water, in high-voltage electrostatic powder coating , due to air ionization, the dust in the air is electrostatically adsorbed to the surface of the electromagnetic wire to produce coating film particles and other disadvantages; when multiple metal wires are painted side by side, due to the Faraday shielding effect between the side-by-side metal wires, the thickness of the coating film is reduced. Uneven etc.

Abstract

The invention relates to a functional coating, in particular to a friction electrostatic spraying infrared curing powder coating for an electromagnetic wire and an enamelled wire. The powder coating consists of a resin, a curing agent, a pigment, a filler and an additives; the powdery coating comprises the following compositions by mass percentage: 33 to 62 percent of the thermosetting resin, 5 to 33 percent of the curing agent, 1 to 29 percent of the pigment and the filler, 0.5 to 1 percent of triboelectric additive, 0.5 to 1 percent of powder loosening additive and 1 to 5 percent of other additives; a preparation process comprises: the compositions of a formula are subjected to premixing and melt extrusion and mixing, are cooled to room temperature and are broken into a sheet material; the sheet material is pulverized to ultrafine powder and is separated to obtain a semifinished product of powder coating with less than 160 meshes; and the semifinished product is demagnetized to obtain a finished product. The friction electrostatic spraying infrared curing powder coating for the electromagnetic wire and the enamelled wire does not produce wastewater, waste gas and waste residue in the production process, does not produce any pollution to environment, has high utilization rate and belongs to a resource-saving type product.

Description

technical field [0001] The invention relates to a functional coating, in particular to a friction electrostatic spraying infrared curing powder coating for electromagnetic wires and enameled wires. Background technique [0002] With the rapid development of industrial production, the pollution of ecological environment caused by waste water, waste gas and waste residue produced in industrial production has become a serious problem worldwide. Therefore, our country also attaches great importance to the protection of the ecological environment, has repeatedly emphasized the prevention of environmental pollution caused by industrial development, and requires the development of non-polluting industries to benefit mankind. [0003] With the needs of my country's modern industrial construction and export, the consumption of electromagnetic wires and enameled wires in industries such as electromechanical, electronics, communications, and automation control continues to increase. At...
