Problems solved by technology

[0003] In the article "Research on NI-PTFE Composite Electroplating Process", the author proposed that the Ni / PTFE composite coating was successfully prepared by adding polytetrafluoroethylene emulsion and FC134 cationic surfactant to the electroplating solution. In terms of mechanical properties, the friction coefficient of the composite coating is 0.218, which is only about 34% of the pure nickel coating. However, due to the softness of PTFE, after entering the coating, the hardness of the composite coating is reduced compared with that of the pure nickel coating, and at the same time, the amount of wear is somewhat reduced. Increase
Therefore, in some fields, this composite coating cannot meet the demand

Embodiment Construction

[0013] An antistatic composite electroplating solution for scaffolding, prepared from the following raw materials in parts by weight (kg): attapulgite 8, dextrin 3, aniline 6.8, ammonium persulfate 0.1, boric acid 50, nickel sulfate 220, nickel chloride 40 , sodium lauryl sulfate 0.2, polytetrafluoroethylene emulsion 50, cationic surfactant FC1343, cerium oxide 1.5, appropriate amount of ethanol, appropriate amount of deionized water.

[0014] Described a kind of scaffold antistatic composite electroplating solution is prepared by following specific steps:

[0015] (1) Soak the attapulgite in 2mol / L hydrochloric acid solution for 5 hours, wash it with deionized water, and then dry it, then add dextrin to twice the amount of deionized water, heat and stir to form a paste Add cerium oxide, then place it in an inert gas at 200°C for 0.5h, and cool it for later use;

[0016] (2) Add dodecylbenzenesulfonic acid, water, aniline and n-butanol into the flask at a molar ratio of 1.5:1...

Abstract

The invention discloses scaffolding antistatic composite electroplate liquid. The scaffolding antistatic composite electroplate liquid comprises, by weight, 8-14 parts of attapulgite, 3-4 parts of dextrin, 6.8-9 parts of aniline, 0.1-0.2 part of ammonium persulfate, 50-60 parts of boric acid, 220-250 parts of nickel sulfate, 40-50 parts of nickel chloride, 0.2-0.3 part of lauryl sodium sulfate, 50-60 parts of teflon emulsion, 3-4 parts of a cationic surface active agent FC134, 1.5-3 parts of cerium oxide, a proper amount of ethyl alcohol and a proper amount of deionized water. The scaffolding antistatic composite electroplate liquid is simple in technology, the quality of obtained products is qualified, and the phenomenon of peeling is avoided; and the color and luster are uniform, the phenomenon of partial white spots is avoided, the surface is smooth and free of the sense of roughness, and therefore the scaffolding antistatic composite electroplate liquid is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of electroplating solutions, in particular to a scaffold antistatic composite electroplating solution. Background technique [0002] Electroplating, also known as metal electrodeposition technology, is a process in which the workpiece is immersed in a solution containing the metal salt to be deposited, and a negative charge is applied to the workpiece to deposit a layer of metal or alloy layer that is closely bonded to the workpiece on the surface of the workpiece. The basic principle of electroplating is to reduce the metal ions in the solution on the interface between the solution and the plated parts through the action of various electric fields, generate metal atoms and deposit them on the metal surface to form a coating. Composite coating is a surface modification technology that adds insoluble solid particles to the plating solution to cause co-deposition of matrix metal and solid particles to form a c...
