Abstract

The invention provides a gouging carbon rod copper plating surface anti-blushing agent and a preparation method and application thereof, and belongs to the technical field of chemical agents.The anti-blushing agent is prepared from, by weight, 0.2-0.4 g of a sulfydryl organic compound, 0.4-0.6 g of organic phosphonic acid, 0.2-1 g of ethylene diamine tetraacetic acid, 0.2-0.4 g of sodium sulfate, 0.2-0.4 g of sodium silicate, 0.2-0.4 g of sodium dihydrogen phosphate dihydrate, 0.2-0.4 g of sodium chloride, 0.2-0.4 g of sodium chloride, 0.2-0.4 g of sodium chloride, 0.2-0.4 g of sodium chloride, 0.2-0.4 g of sodium chloride, 0.2-0.4 g of sodium chloride and the balance water. 5-10 g of absolute ethyl alcohol and 1000 g of water; according to the anti-tarnishing agent disclosed by the invention, a protective film with anti-tarnishing capability can be generated on the surface of a gouging carbon rod copper-plated product; the copper-plated carbon arc gouging carbon rod subjected to surface treatment is not rusted after being subjected to a damp-heat experiment for 240 hours, has no obvious appearance change after being placed indoors for 3 months, and is simple in preparation and application process, safe and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of chemical agents, in particular to an anti-discoloration agent on the copper-plated surface of a gouging carbon rod, a preparation method and an application thereof. Background technique [0002] Copper has excellent electrical conductivity, ductility and low impedance properties, and its beautiful metallic color makes it widely used in the surface treatment of carbon arc gouging carbon rods. Due to the active chemical properties of copper, copper-plated carbon arc gouging carbon rods are often exposed to humid environments, exposure to oxygen, carbon dioxide, sulfur dioxide and other gases in the air and microbial sedimentation during storage, which is prone to surface copper corrosion. Changes in copper surface color affect the appearance and electrical conductivity of carbon arc gouging rods. In order to further improve the corrosion resistance of carbon arc gouging carbon rods in the atmosphere, it is...
