Problems solved by technology

[0003] In traditional industries, different materials require different cleaning agents and cleaning equipment, and the protective treatment after cleaning also requires different processing agents, which increases the purchase cost and the time for cleaning and protection between processes.
At the same time, due to the complex process and poor continuity of production during the cleaning process, the pollution discharge load is increased; and after a period of time after cleaning, the workpiece needs to be cleaned again, and the maintenance time is short

Embodiment Construction

[0014] A metal surface treatment f method, characterized in that: firstly, the metal surface treatment agent is diluted 8-9 times with water, and the working fluid with a pH value of 8.0-9.0 is controlled by adding an acid-base regulator. Ultrasonic cleaning or spraying method is used to clean the surface of non-ferrous metals for 3-4 minutes, and dry in the temperature range of 10°C-120°C; the components of the metal surface treatment are: corrosion inhibitor, surfactant , chitosan, antioxidant, titanium dioxide, silicon dioxide and water, the content of each substance by weight percentage is as follows: corrosion inhibitor 0.5-8.0, surfactant 2.0-9.0, chitosan 2.0-8.5, antioxidant 0.1- 1.0, titanium dioxide 1.5-9.0, silicon dioxide 1.5-9.0, water balance.

[0015] The preparation process of the metal treatment agent is as follows: stir 0.5-8.0% corrosion inhibitor with 2.0-9.0% surfactant, then add 20% deionized water and mix thoroughly, then heat to 60°C-70°C, fully Stir f...

Abstract

The invention relates to a metal surface treatment method, in particular to an environment-friendly non-ferrous metal surface treatment method, belonging to the technical field of surface cleaning and surface rust prevention treatment of metal. The method comprises the steps of diluting a metal surface treatment agent with water which is 8-9 times as much as the metal surface treatment agent; adding an acidifying or alkalizing agent to control the PH value of working solution to be 8.0-9.0, and cleaning the surface of non-ferrous metal for 3-4min by ultrasonic waves or in a spraying mode at normal temperature or 50-60 DEG C and drying in a temperature range from 10 DEG C to 120 DEG C; when the method is adopted, nanoscale titanium dioxide and nanoscale silicon dioxide form a protective membrane layer on the surface of the metal, and nanoscale F-doped titanium dioxide and nanoscale silicon dioxide can decompose bacteria on the surface of the metal under the irradiation of sunlight and have high hydrophilcity, so as to fully protect the surface of the metal from being eroded by bacteria and rainwater; therefore, the surface of the metal is protected very well and the protective membrane is formed on the surface of the metal to protect the glossiness of the metal surface.

Description

[0001] technical field [0002] The invention relates to a metal surface treatment method, in particular to an environment-friendly nonferrous metal surface treatment method, which belongs to the technical field of metal surface cleaning and surface antirust treatment. Background technique [0003] In traditional industries, different materials require different cleaning agents and cleaning equipment, and the protective treatment after cleaning also requires different processing agents, which increases the purchase cost and the time for cleaning and protection between processes. At the same time, due to the complex process and poor continuity of production during the cleaning process, the pollution discharge load is increased; and after a period of time after cleaning, the workpiece needs to be cleaned again, and the maintenance time is short. Contents of the invention [0004] In view of the defects in the prior art, the present invention provides a metal surf...
