Acidic double-color material electroplating peptizing solution and preparation method thereof

[0027] Example 1: An acidic dual-color electroplating gel solution

[0028] The acidic two-color material electroplating glue solution in this example includes the following components: 100-160 parts of water, 50-80 parts of oxalic acid, 30-40 parts of sulfamic acid, 10-20 parts of hydrogen peroxide, 6-10 parts of ethylenediaminetetraacetic acid Copies. The water is deionized water; the purity of oxalic acid, sulfamic acid and ethylenediaminetetraacetic acid is analytically pure; the hydrogen peroxide is a 60% hydrogen peroxide aqueous solution.

[0029] Example 2: An acidic dual-color electroplating gel solution

[0030] The components of the acidic two-color material electroplating gel solution in this embodiment are: 130 parts of water, 65 parts of oxalic acid, 35 parts of sulfamic acid, 15 parts of hydrogen peroxide, and 8 parts of ethylenediaminetetraacetic acid.

[0031] Example 3: Preparation method of acidic double-color electroplating gel solution

[0032] See attached figure 1 As shown, a method for preparing an acidic two-color material electroplating gel solution includes the following steps:

[0033] Step 1: Add 80-120 parts of water to the container and heat the water to 60-100°C;

[0034] Step 2: After the water temperature stabilizes, add 50-80 parts of oxalic acid and 30-40 parts of sulfamic acid, continue to heat the container, keep the temperature at 60-100℃, and stir, the stirring speed is 35-45r / min, stirring Last 30-40 minutes, get prefab one;

[0035] Step 3: Add 10-20 parts of hydrogen peroxide to preform 1, continue to stir for 20-30 minutes at a stirring speed of 60-80r / min, and heat the container in a water bath at a temperature of 30-50°C to obtain preform 2;

[0036] Step 4: Add 6-10 parts of ethylenediaminetetraacetic acid to the second preform, and add 20-40 parts of water, airtight the container, keep the container te
