Abstract

The invention discloses an agent for removing aerugo on surfaces of mobile phones and protecting the surfaces of the mobile phones. The agent comprises dust removal liquid, cleaning liquid and protective liquid, wherein the dust removal liquid contains weak corrosivity acid, an acid corrosion inhibitor, a surface active agent, natural plant essence and deionized water; the cleaning liquid comprises a solvent, a surface active agent and natural plant essence; the protective liquid comprises a corrosion inhibitor, natural plant essence, a polishing agent and a solvent. The agent can be used for effectively removing the aerugo on the surfaces of the mobile phones and effectively preventing metals on the surfaces of the mobile phones from being corroded again, and meanwhile is harmless to human bodies, environment-friendly and pollution-free.

Description

technical field [0001] The invention relates to the field of metal rust removal and protection, in particular to the preparation of copper rust removal and protective agent on the surface of mobile phones. technical background [0002] Due to the excellent luster of metal, there are still many mobile phones on the market with metal or metal-plated shells. This kind of mobile phone looks more beautiful and has better stain resistance, so it is favored by many mobile phone users. However, due to the corrosion of hand sweat and other liquids during use, the metal on the surface of the mobile phone case will be corroded or even rusted after a long time, especially some green copper rust exists in places that are not often touched by hands. As a metal with a color similar to gold, copper is very decorative, and it is easy to process and low in cost. It is often used in the manufacture of metal mobile phone cases. However, due to its poor corrosion resistance, copper is used for a...
