Abstract

The invention relates to a preparation method of a tin adsorption material. The preparation method includes: adding (Z)-1-ethyoxyl-2-tributylstannaneethylene and N, N-diallyl-5-methoxytryptamine for polymerization.

Description

technical field [0001] The invention relates to a preparation method of a resin adsorbent, in particular to a preparation method of a tin adsorption material. Background technique [0002] Faults often encountered in nickel plating solutions, such as: pinholes, pitting, peeling, roughness, blackening, blooming, streaks and brittleness, except for a few are caused by imbalance of plating solution components and operating conditions exceeding the process specifications In addition, it is often related to impurities in the plating solution. Tin impurities are sensitive to the nickel plating solution, and when the concentration reaches a certain value, the coating in the low current density area of ​​the plated part will be blackened. In the case of rapid rise in the price of metal nickel, some companies first plate a medium-tin-copper-tin alloy on the workpiece before barrel-plating bright nickel, and then plate a layer of thin nickel, so as to reduce the cost of electroplatin...
