Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and its implementation.

[0028] Please refer to figure 1 ,in figure 1 The experimental data table of the brightener for tin plating and its preparation method provided by the present invention; figure 2 for figure 1 Dispersing Power Data Sheet for the tinning brighteners described. A tin plating brightener, raw materials include glutaraldehyde, dihydroxypropanethiol, cinnamaldehyde, alkylphenol polyoxyethylene ether and water;

[0029] Its raw material ratio is as follows:

[0030] 55-80 parts of glutaraldehyde, 60-90 parts of dihydroxypropanethiol, 5-10 parts of cinnamaldehyde, 55-85 parts of alkylphenol polyoxyethylene ether, 300-400 parts of water.

[0031] Described glutaraldehyde is 65 parts, and dihydroxypropanethiol is 75 parts, and cinnamaldehyde is 8 parts, and alkylphenol polyoxyethylene ether is 80 parts, and through glutaraldehyde is 65 parts, and dihyd...

Abstract

The invention provides a tinning brightener and a preparing method thereof. Raw materials include glutaraldehyde, dyhydroxy propanethiol, cinnamyl aldehyde, alkylphenol ethoxylates and water. The rawmaterials include 55-80 parts of glutaraldehyde, 60-90 parts of dyhydroxy propanethiol, 5-10 parts of cinnamyl aldehyde, 55-85 parts of alkylphenol ethoxylates and 300-400 parts of water. Through cooperation of mixing, cooling, additive adding, carrier brightener adding and product forming work processes, the situation that Sn2+ is likely to be oxidized by an anode during electrolysis is preventedthrough dyhydroxy propanethiol, and long-term stability of a plating solution is improved; meanwhile, the chemical activity of glutaraldehyde carbonyl is particularly high, meanwhile, the Sn2+ adsorption capability is improved, and then brightness of the tinning brightener is improved; meanwhile, influences are generated to glutaraldehyde adsorption from cinnamyl aldehyde, the potential, adsorbedto the surface of an electrode, of the glutaraldehyde becomes narrow, accordingly, fine crystalline particles are generated, an auxiliary function is achieved for clad layer brightness increasing, and brightness of the tinning brightener is improved.

Description

technical field [0001] The invention relates to the field of brighteners for tin plating, in particular to a brightener for tin plating and a preparation method thereof. Background technique [0002] Tin plating brighteners are divided into two types: organic and inorganic. Organic brighteners are beneficial to reef castor oil, sulfite paper slurry, dextrin, cayenolsulfonic acid, etc. They can improve the cathodic polarization and dispersion ability, and make the coating crystallize It is fine and shiny, and can cover metal impurities. Inorganic brighteners include nickel sulfate or cobalt salt. Commonly used nickel sulfate can improve the physical properties of the coating and enhance the gloss. However, the brightener should not be excessive to prevent the coating from becoming brittle and blistering. [0003] Tin plating brighteners are widely used in reality, and users need to prepare a large amount of tin plating brighteners. However, traditional tin plating brighteners...
