Phytic acid cleaning agent

Abstract

The present invention relates to cleaning agent, and is especially one kind of reducing cleaning agent for the surface of copper or copper alloy material. The cleaning agent consists of phytic acid 2.5-10 wt%, alcohol amine 0.8-2.0 wt%, polyethylene addition cd type non-ionic surfactant 0.6-2.0 wt% and co-solvent 1.0-8.0 wt% except water. Replacing traditional dilute sulfuric acid, hydrochloricacid, nitric acid, etc. with phytic acid makes the cleaning agent possess no demerits like those of traditional cleaning agent and environment friendly. The cleaning agent with organic acid results in stable quality of the cleaned copper or copper alloy surface, has no injury to clothing and skin, no stimulating smell, and is reusable.

Description

1. Technical field [0001] The invention relates to a cleaning agent, in particular to a surface reduction cleaning agent for copper or copper alloy profiles. 2. Background technology [0002] A copper oxide (CuO) and cuprous oxide (Cu 2 O) Oxide film composed of. To remove oxides on the surface of copper or copper alloys, the traditional method is to use chemical corrosion, that is, after hot copper or copper alloys are rolled out, the circulation pipes are cleaned by inorganic acids (such as dilute sulfuric acid, hydrochloric acid, nitric acid) , After pickling and then washing and waxing. Due to the many shortcomings of this traditional method, such as complicated cleaning process, waste copper acid solution needs to be treated and regenerated, which means waste liquid pollution, etc., it has been gradually replaced by reducing cleaning agents. Announced a kind of " surface cleaning agent for copper or copper alloy profile " (application number 87101262, approval number...
