Combination type zincate galvanizing brightener

Abstract

The invention provides a combination type zincate zinc-plating brightener, wherein the urotropin, the dimcthylamine of which the concentration is 33 percent and the water are added in a reactor, the formaldehyde of which the concentration is 37 percent is dripped in the reactor and stirred for 30 minutes, the chloroepoxy propane is dripped down, the mixed liquid is heated up to the reflux temperature and the heat is preserved for 2 hours. The invention has the advantages of good physical properties of the plating coat, wide range of the current density, bright and even colors and low cost.

Description

technical field [0001] The invention relates to a combined zincate galvanizing brightener. Background technique [0002] At present, in the use of two-component brighteners, it is easy to have an improper ratio of additives and brighteners, resulting in electroplating failures. The current density range is narrow. Flowering, unevenness. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects and provide a combination zincate galvanizing brightener. [0004] The technical scheme of the present invention is: a combined zincate galvanizing brightener, characterized in that: the formula is: 0.1-1mol of heterocyclic nitrogen-containing compound, 0.5-5mol of fatty amine, 0-1mol of aldehyde, epichlorohydrin 0.5-7mol, add heterocyclic nitrogen-containing compounds, amines and aldehydes, and appropriate amount of water into the bottle, stir and drop epichlorohydrin, keep warm for 1-8 hours, and add to the zincate plating ...
