Copper detergent

Abstract

The invention discloses a copper detergent which is composed of the following raw materials: 15-20 parts of metatitanic acid, 15-20 parts of thiosulfuric acid, 15-20 parts of phosphorous acid, 20-25 parts of fluoboric acid, 8-10 parts of zinc hydroxide, 5-10 parts of aluminum sulfate, 15-18 parts of phosphoric acid, 5-10 parts of tartaric acid, 8-10 parts of oxalic acid, 3-5 parts of cocooctyl phenol polyethenoxy ether, 5-6 parts of fatty alcohol polyethenoxy ether, 5-8 parts of isoalcohol polyethenoxy ether, 4-5 parts of diethylene glycol aether, 5-7 parts of glycol ether acetate, 6-8 parts of propylene glycol methyl ether acetate, 6-8 parts of emulsified silicone oil, 8-10 parts of polydimethylsiloxane, 6-8 parts of glycerol, 3-5 parts of ethylene glycol monophenyl ether, 4-5 parts of sodium alginate, 5-6 parts of ammonium citrate and 200-250 parts of deionized water. The copper detergent lowers the consumption of three industrial strong acids, lowers the health hazard to the operating personnel and avoids generating over etching on the copper substrate. After being cleaned by the copper detergent and flushed with distilled water, the copper part has the advantages of uniformly distributed surface water film and no oil stain residue.

Description

technical field [0001] The invention relates to the technical field of a cleaning agent, in particular to a copper cleaning agent. Background technique [0002] Copper and its alloys are widely used in material engineering due to their excellent electrical conductivity, thermal conductivity and ductility, especially in the high-voltage electrical industry as conductive contact surfaces. During the use of copper alloys, different use environments such as alkaline, acidic, neutral solutions and marine environments can cause corrosion of copper alloys, thereby affecting their electrical conductivity; in the electrical industry, copper is used as a conductive contact surface , before assembly or electroplating, it is necessary to ensure that the surface is clean. The surface of the copper part must be cleaned. The quality of the cleaning directly affects the performance and quality of the subsequent film layer. [0003] The volatilization of the acid solution during the use of ...
