Embodiment 1

[0022] Nickel satin solution comprises the following formula: nickel sulfate, weight ratio 280g / L; nickel chloride, weight ratio 42g / L; boric acid, weight ratio 31g / L; brightener propynyl alcohol propoxy compound, volume ratio 3ml / L L, to provide better gloss and flatness for the coating; the surfactant succinate salt anionic surfactant, with a volume ratio of 8ml / L, makes the satin nickel coating produce a pearlescent effect; the softener propynyl sodium sulfonate , the volume ratio is 1ml / L, which helps to improve the gloss of the coating in the low current density area; the displacement agent sodium allyl sulfonate, the volume ratio is 2ml / L, which makes the satin nickel coating more uniform and reduces the probability of missing plating .

[0023] In order to ensure the nickel plating effect of the satin nickel solution, the nickel plating process includes the following steps:

[0024] Step 1, using 500 mesh sand to carry out frosting treatment on the surface of the mater...

Embodiment 2

[0027] Nickel satin solution comprises the following formulations: nickel sulfate, weight ratio 380g / L; nickel chloride, weight ratio 58g / L; boric acid, weight ratio 38g / L; brightener propanesulfonic acid pyridinium salt, volume ratio 7ml / L , to provide better gloss and smoothness for the coating; the surfactant is composed of succinate salt anionic surfactant, carboxylate anionic surfactant, and quaternary ammonium salt anionic surfactant, and the addition ratio is 5 :2:3, the total volume ratio of the three surfactants is 15ml / L, which makes the satin nickel coating produce a pearlescent effect; the softener sodium propynyl sulfonate, with a volume ratio of 5ml / L, helps to improve the low current density area Glossiness of the coating; sodium salt of hydroxyl compound sulfonate as a displacement agent, with a volume ratio of 2ml / L, which makes the satin nickel coating more uniform and reduces the probability of missing plating.

Abstract

The invention discloses a satin nickel solution and a nickel plating process thereof. The formula of the satin nickel solution comprises the following components in proportion by weight and volume: 280g / L-380g / L of nickel sulfate, 42g / L-58g / L of nickel chloride, 31g / L-38g / L of boric acid, 3ml / L-7ml / L of a brightener, 8ml / L-15ml / L of a surfactant, 1ml / L-5ml / L of a softening agent, 2ml / L-4ml / L of a walking agent, and 0.2g / L-10g / L of water soluble fiber, wherein the length of the water soluble fiber is 2mm-4mm. For guaranteeing the nickel plating effect of the satin nickel solution, the nickel plating process comprises the following steps: (1) polishing the surface of the to-be-nickel plated material by virtue of 500-1000-mesh sand, so as to increase the specific surface area and roughness of the surface of the to-be-nickel plated material and the adhesive force of a satin nickel plated layer; and (2) carrying out surface nickel plating by taking the to-be-nickel plated material as a cathode and a nickel plate as an anode, so as to guarantee the use effects of the brightener, the surfactant, the softening agent, the walking agent and the water soluble fiber, wherein the temperature is controlled at 42-48 DEG C, the pH value is controlled at 3-5, and the electric current density is controlled at 3A / dm<2>-8A / dm<2>.

Description

technical field [0001] The invention relates to the field of electroplating nickel, in particular to a nickel satin solution and a nickel plating process thereof. Background technique [0002] Sardine nickel, also known as pearl nickel, satin nickel, pitted nickel, is a coating with gorgeous appearance, fine and soft color, low internal stress and good corrosion resistance. It is a good protective decorative coating. The satin nickel plating process first appeared in the 1950s and developed rapidly after the 1990s. Sardine nickel can be directly used as a protective decorative coating, or it can be plated with other metals on the pearl nickel, such as chromium, gold, silver, etc., and its protective decorative effect is stronger. At present, satin nickel coating has been widely used in automobile decoration, electronic products, daily hardware, stationery and other industries. [0003] At present, the satin nickel coating still has the phenomenon of insufficient adhesion s...
