Problems solved by technology

[0003] However, at present, most of the tinning methods for copper parts are electroplating. Although it can achieve the effect of electroplating, its disadvantages are high working temperature, low current efficiency, high energy consumption, high cost, and prone to dull phenomena. , it is difficult to guarantee product quality
In addition, there are also disadvantages such as fluoride pollution and difficult wastewater treatment, which is not conducive to environmental protection.

Abstract

The invention discloses a copper ecological tinplating water-based process material, which is prepared from the following raw materials in percentage by mass: 0.1 to 3 percent of emulgator, 0.2 to 0.5 percent of dispersing agent, 1 to 3 percent of penetrating agent, 0.5 to 6 percent of organic acid, 0.2 to 8 percent of hexamethylenetetramine, 3 to 9 percent of stannous chloride, 0.3 to 5 percent of neutral salt, 1 to 11 percent of organic salt, and the balance pure water. According to the copper ecological tinplating water-based process material provided by the invention, a formula is reasonable, a direct-current power supply has no need to be added, a heating source is not needed, a copper piece to be plated is adopted as a cathode, and a tin ion of the copper ecological tinplating water-based process material is combined with the copper piece to be plated through an ion exchange manner by utilizing different electric potentials exited in the copper piece to be plated, so that a layer of compact tinplating layer with uniform thickness is formed on a surface of the copper piece to be plated, a tinplating effect is good, and the combination property and the service life of the product are effectively improved; and in addition, a tinplating method is concise in processing steps, easy to implement, high in tinplating efficiency, low in cost, energy-saving and environmentally-friendly, and beneficial to be widely popularized and applied.

Description

technical field [0001] The invention relates to the technical field of tinning of copper parts, in particular to a copper ecological tinning water-based process material and a tinning method thereof. Background technique [0002] The application of electroplating tin is very extensive. Tin has the advantages of corrosion resistance, discoloration resistance, non-toxicity, easy brazing, softness, low melting point and good ductility. Dense, uniform and continuous alloy coating. After the copper parts are electroplated with tin, tin has the advantages of high strength, good weldability, good corrosion resistance and non-toxic plating solution. It is a kind of functional material and can be widely used in industries such as automobiles, medicine, light industry and home appliances. [0003] However, at present, most of the tinning methods for copper parts are electroplating. Although it can achieve the effect of electroplating, its disadvantages are high working temperature, l...
