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
The present invention relates to a kind of environmentally friendly normal temperature copper alloy blackening agent for surface.
Background technology
To meet requirement of the decorations industry for copper alloy surface color and decay resistance, at present conventional high temperature blackening agent for surface processes copper alloy surface, so as to obtain black or browned surface.This high temperature blackening agent for surface needs to can be only achieved preferably decoration and anticorrosion effect under 90 degrees Celsius of conditions above, and heavy metal environmental pollution contained therein is very big.The present invention can carry out surface blackening process under normal temperature condition to copper alloy, and the present invention is applied in into copper alloy surface, after surface color is changed into black or brown, that is, completes blackening and improve alloy corrosion resistance energy simultaneously.Because content of beary metal is low contained by the present invention, and consume completely during the course of the reaction.Therefore the characteristics of copper alloy blackening agent for surface that the present invention is provided has environmental protection and energy saving.
The content of the invention
For the deficiencies in the prior art, the technical problem to be solved is to provide a kind of environmentally friendly normal temperature copper alloy blackening agent for surface, and content of beary metal is low, and reaction is complete, normal-temperature reaction, with environmental protection and energy saving and it is easy to operate the characteristics of.
To solve above-mentioned technical problem, the present invention adopts the technical scheme that a kind of environmentally friendly normal temperature copper alloy blackening agent for surface is made up of the raw material of following mass fraction：Water 6-10 parts, the sub- selenium 0.1-0.5 parts of oxidation, methenamine 0.1-0.6 parts, OP-10 0.1-0.5 parts, NNO 0.1-0.5 parts, copper nitrate 0.1-1 parts, nickel nitrate 0.1-1 parts.
The technical scheme of present invention optimization is that a kind of environmentally friendly normal temperature copper alloy blackening agent for surface is made up of the raw material of following mass fraction：6 parts of water, sub- 0.1 part of the selenium of oxidation, 0.1 part of methenamine, 0.1 part of OP-10,0.1 part of NNO, 0.1 part of copper nitrate, 0.1 part of nickel nitrate.
The technical scheme of present invention optimization is that a kind of environmentally friendly normal temperature copper alloy blackening agent for surface is made up of the raw material of following mass fraction：10 parts of water, sub- 0.5 part of the selenium of oxidation, 0.6 part of methenamine, 0.5 part of OP-10,0.5 part of NNO, 1 part of copper nitrate, 1 part of nickel nitrate.
The technical scheme of present invention optimization is that a kind of environmentally friendly normal temperature copper alloy blackening agent for surface is made up of the raw material of following mass fraction：8 parts of water, sub- 0.2 part of the selenium of oxidation, 0.5 part of methenamine, 0.2 part of OP-10,0.2 part of NNO, 0.4 part of copper nitrate, 0.3 part of nickel nitrate.
The invention has the beneficial effects as follows, the environmentally friendly normal temperature copper alloy blackening agent for surface of the present invention, content of beary metal is low, and reaction is complete, normal-temperature reaction, with environmental protection and energy saving and it is easy to operate the characteristics of.
