Problems solved by technology

[0004] At present, there is only a single brightener for zinc or zinc-iron alloy electroplating at home and abroad, and there is no brightener and its preparation process that can be used for zinc and zinc-iron alloy electroplating at the same time, so that the application of zinc or zinc-iron alloy electroplating brightener and its electroplating process is limited. A large limit, but also bring great inconvenience to users
For example, the ZF series additives developed by Chengdu High-tech Electroplating Environmental Engineering Research Institute are very good brighteners for electrogalvanized ferroalloys, but they cannot be used in the galvanizing process, so their promotion and application have been greatly restricted.

Embodiment 1

[0015] Embodiment 1: the specific preparation process of this zinc and zinc-iron alloy electroplating brightener is as follows:

[0016] First weigh the benzylidene acetone according to 10g / L, then pour it into 100mL / L analytical pure absolute ethanol, and stir until it is completely dissolved. Then weigh the drug according to the total amount of 100g / L, the mass ratio of higher fatty alcohol cetyl natural fatty alcohol to ethylene oxide is 1:20, and carry out condensation reaction with anhydrous aluminum chloride as the condensing agent. Then weigh the drug according to the total amount of 100g / L, the mass ratio of the non-ionic surfactant polyethylene glycol and the ionic surfactant sodium dodecylbenzenesulfonate is 3:1, and the prepared high-grade fat Pour alcohol and ethylene oxide condensate into 3 times the mass of distilled water, heat to 80°C, stir until completely dissolved, then cool naturally, then mix with the prepared solution of benzylidene acetone and ethanol, a...

Embodiment 2

[0019] Embodiment 2: the specific preparation process of this zinc and zinc-iron alloy electroplating brightener is as follows:

[0020] Firstly weigh the benzylidene acetone according to 30g / L, then pour it into 600mL / L analytical pure absolute ethanol, and stir until it is completely dissolved. Then weigh the drug according to the total amount of 120g / L, the mass ratio of higher fatty alcohol octadecyl natural fatty alcohol to ethylene oxide is 1:25, and carry out the condensation reaction with anhydrous zinc chloride as the condensing agent. Then by total amount 130g / L, the mass ratio of nonionic surfactant polyethylene glycol and ionic surfactant sodium lauryl sulfate is 10:1 to weigh medicine, and the higher fatty alcohol that has been prepared and Pour the ethylene oxide condensate into 2 times the mass of distilled water together, heat to 85°C, stir until completely dissolved, then cool naturally, then mix with the prepared solution of benzylidene acetone and ethanol, a...

Embodiment 3

[0023] Embodiment 3: the preparation process of this zinc and zinc-iron alloy electroplating brightener is as follows:

[0024] First weigh the benzylidene acetone according to 20g / L, then pour it into 300mL / L analytical pure absolute ethanol, and stir until it is completely dissolved. Then weigh the drug according to the total amount of 80g / L, the mass ratio of higher fatty alcohol cetyl natural fatty alcohol to ethylene oxide is 1:10, and carry out the condensation reaction with sulfuric acid as the condensation agent. Then weigh the medicine according to the mass ratio of 70g / L of the total amount, nonionic surfactant OP emulsifier and ionic surfactant sodium dodecylbenzenesulfonate to 5:1, and the prepared higher fatty alcohol Pour into 4 times the mass of deionized water together with the ethylene oxide condensate, heat to 90°C, stir until completely dissolved, then cool naturally, then mix with the prepared solution of benzylidene acetone and ethanol, and then use deioni...
