Problems solved by technology

[0002] In the field of metal surface treatment, although traditional phosphate conversion and chromate passivation surface treatment technologies can achieve good results, the waste liquid discharged during the treatment process contains heavy metal ions such as zinc, manganese, nickel, chromium and nitrous acid. Carcinogens such as salt are very serious for environmental pollution

Abstract

The invention provides a silanization processing agent for metal piece individually protection, which is a mixed solution prepared by the following components, and in each liter of the mixed solution, the weight parts of the components are: 30-60 g of 1,2-diethoxylsilyl ethane, 2-5 g of sodium molybdate, 0.5-1.5 g of alpha-sulfo fatty acid methyl ester sodium, 0.1-0.4 g of ethylenediaminetetraacetic acid disodium salt, 4-7 g of isopropanol, and the balance of ethanol solution. The processing agent of the invention is stable in performance, simple in preparation, nontoxic, and free of pollution. When a metal piece is processed by the processing agent of the invention, a film layer formed on the metal surface has the characteristics of strong adhesion, compactness, uniformity, and small polarization current density, which improves the deficiencies of existing metal surface pretreatment, allows better application of metal surface pretreatment, and substitutes phosphatization and blackening technology.

Description

technical field [0001] The invention relates to the field of metal surface treatment, in particular to a silanization treatment agent for individual protection of metal parts. Background technique [0002] In the field of metal surface treatment, although traditional phosphate conversion and chromate passivation surface treatment technologies can achieve good results, the waste liquid discharged during the treatment process contains heavy metal ions such as zinc, manganese, nickel, chromium and nitrous acid. Carcinogens such as salt are very serious to environmental pollution. The metal surface silanization treatment technology is considered to be expected to replace phosphate conversion treatment and chromate passivation treatment because it does not involve substances that are harmful to the environment, the production process has low energy consumption, and the technology has a wide range of application fields. It is the latest development direction of metal surfa...
