Abstract

The invention discloses an environment-friendly electroplate liquid. The environment-friendly electroplating liquid consists of the following components: 180-280g/L of chromium sulfate, 50-80g/L of sodium sulfate, 10-15g/L of ammonium formate, 40-160g/L of sodium oxalate, 1-5g/L of glycine, 5-40g/L of urea, 50-100g/L of sodium borate, 100-150g/L of potassium sulphate, 1-5g/L of potassium citrate, 40-80g/L of potassium chloride, 2-8g/L of glycine and the balance of deionized water. The environment-friendly electroplate liquid has the characteristics of nontoxicity, harmlessness, no corrosion, storage stability and the like, and is relatively good in environment friendliness, and the surface covering capability of the prepared electroplating layer for electroplating products is intensified.

Description

A kind of environmental protection electric plating solution

Technical field

The present invention relates to electroplate liquid field, particularly relate to a kind of environmental protection electric plating solution.

Background technology

Chromium has excellent ornamental and functional, and its hardness is large, frictional coefficient is little, is all extraordinary metal of a kind of wear resistance and thermotolerance, so chromium application is in the industry comparatively extensive.The most general industrialization process of current use is sexavalent chrome chromium plating, but chromic seriously polluted, huge to the harm of human body and surrounding environment.The World Health Organization, Europe and the U.S. etc. more and more pay close attention to chromic harm, constantly reduce the emission standard of hexavalent chromium wastewater.Trivalent chromium plating, as most important, the most direct effective hexavalent chromium plating technique that substitutes, all must have unrivaled superiority by hexavalent chromium plating from processing performance or environment protection.

Summary of the invention

The technical problem that the present invention mainly solves is to provide a kind of environmental protection electric plating solution, has the features such as nontoxic, harmless, corrosion-free, shelf-stable.

For solving the problems of the technologies described above, the technical scheme that the present invention adopts is:

A kind of environmental protection electric plating solution is provided, be made up of following component: chromium sulphate 180 ~ 280g/L, sodium sulfate 50 ~ 80 g/L, ammonium formiate 10 ~ 15 g/L, sodium oxalate 40 ~ 160 g/L, Padil 1 ~ 5 g/L, urea 5 ~ 40 g/L, Sodium Tetraborate 50 ~ 100 g/L, potassium sulfate 100 ~ 150g/L, Tripotassium Citrate 1 ~ 5 g/L, Repone K 40 ~ 80 g/L and glycine 2 ~ 8 g/L, surplus is deionized water.

In a preferred embodiment of the present invention, this environmental protection electric plating solution is made up of following component: chromium sulphate 240g/L, sodium sulfate 70 g/L, ammonium formiate 12 g/L, sodium oxalate 120 g/L, Padil 3 g/L, urea 15 g/L, Sodium Tetraborate 60 g/L, potassium sulfate 125g/L, Tripotassium Citrate 3 g/L, Repone K 60 g/L and glycine 6 g/L, surplus is deionized water.

In a preferred embodiment of the present invention, this environmental protection electric plating solution is made up of following component: chromium sulphate 280g/L, sodium sulfate 60 g/L, ammonium formiate 10g/L, sodium oxalate 80 g/L, Padil 5 g/L, urea 35 g/L, Sodium Tetraborate 80 g/L, potassium sulfate 120g/L, Tripotassium Citrate 4 g/L, Repone K 50 g/L and glycine 3 g/L, surplus is deionized water.

In a preferred embodiment of the present invention, this environmental protection electric plating solution is made up of following component: chromium sulphate 200g/L, sodium sulfate 65 g/L, ammonium formiate 10 g/L, sodium oxalate 150 g/L, Padil 4 g/L, urea 10 g/L, Sodium Tetraborate 100 g/L, potassium sulfate 100g/L, Tripotassium Citrate 2g/L, Repone K 80 g/L and glycine 5 g/L, surplus is deionized water.
