Plug paint for eliminating electric spark

Abstract

The invention discloses plug paint for eliminating electric spark. The plug paint is prepared by combining and mixing graphite, silicon carbide, zinc oxide, epoxy resin, curing agents, dispersing agents, tin oxide and solvents, coating the mixture onto a plug metal sheet, and performing drying. The paint has the advantages that simplicity and practicability are realized; the cost is low; the electric spark generated during plug plugging and unplugging can be eliminated; the contact erosion burnt damage is avoided; the potential safety hazards are eliminated.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a plug coating for eliminating electric sparks. Background technique [0002] The moment the electrical plug is inserted into the socket, due to the existence of a large starting current, sparks and heat will be generated at the contact point. With the stable contact between the plug and the socket contacts, the sparks and heat will disappear. When the electrical plug is pulled out When using a socket, often due to the existence of the load, sparks will also be generated at the moment when the contacts are separated. Due to the existence of electric sparks, the socket contacts and plug contacts of the socket will be continuously eroded, and in severe cases, the socket contacts and plugs will be burned. In addition, the sparks and heat of the power contacts in flammable and explosive places can easily cause explosion accidents. Contents of the invention [0003] The object of ...
