Abstract

The invention provides an environment-friendly normal-temperature copper alloy blackening agent. The environment-friendly normal-temperature copper alloy blackening agent is composed of, by mass, 6-10 parts of water, 0.1-0.5 part of selenium oxide, 0.1-0.6 part of urotropine, 0.1-0.5 part of OP-10, 0.1-0.5 part of NNO, 0.1-1 part of copper nitrate and 0.1-1 part of nickel nitrate. According to the environment-friendly normal-temperature copper alloy blackening agent, the content of heavy metal is low, reaction is sufficient and occurs at normal temperature, and the environment-friendly normal-temperature copper alloy blackening agent has the characteristics of being environmentally friendly, saving energy and being easy and convenient to operate.

Description

technical field [0001] The invention relates to an environment-friendly normal-temperature copper alloy blackening agent. Background technique [0002] In order to meet the requirements of the decoration industry for the surface color and corrosion resistance of copper alloys, high-temperature blackening agents are commonly used to treat the surface of copper alloys to obtain black or brown surfaces. This high-temperature blackening agent needs to achieve ideal decoration and corrosion resistance effects under conditions above 90 degrees Celsius, and the heavy metals contained therein are extremely polluting to the environment. The present invention can carry out surface blackening treatment on the copper alloy under normal temperature condition, apply the present invention on the copper alloy surface, after the surface color changes to black or brown, the blackening process is completed and the corrosion resistance performance of the alloy is improved at the same time.
