Combination type zincate galvanizing brightener

Abstract

The invention provides a combination type zincate zinc-plating brightener, wherein 13.6g of the imidazole, 10.3g of the triethylene-tetramine, 30ml of the formalin of which the concentration is 37 percent and 15ml of the water are added in a reactor, the reactor is heated up to reach the temperature of 40 DEG C, the chloroepoxy propane is dripped down at a temperature below 80 DEG C, the temperature is risen to 140 DEG C and the heat is preserved. 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, causing electroplating failures, and 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 s...
