Example Embodiment

[0037] Example 1:

[0038] In this embodiment, the anticorrosive solution used on the surface of copper and copper alloys is formed by the reaction of mercaptopropyltrimethoxysilane and tetraethoxysilane in an ethanol solvent in the presence of a hydrolysis catalyst solution: a formic acid solution with pH=3. The hydrolysis product; wherein the mass ratio of mercaptopropyltrimethoxysilane to tetraethoxysilane is 588:208.

[0039] The preparation process of the above antiseptic solution is as follows:

[0040] Add 588g mercaptopropyltrimethoxysilane, 208g tetraethoxysilane and 1000g ethanol into a flask equipped with a mechanical stirrer, add 540g hydrolysis catalyst solution: pH=3 formic acid aqueous solution under stirring conditions to make the reaction system Hydrolysis reaction occurred during the reaction. After the reaction was completed, it was stirred at room temperature for 5 hours, and a clear solution was obtained after standing.

Example Embodiment

[0041] Example 2:

[0042] In this embodiment, the anti-corrosion liquid used on the surface of copper and copper alloys is basically the same as the anti-corrosion liquid in Example 1. The difference is: the quality of mercaptopropyltrimethoxysilane and tetraethoxysilane in this embodiment The ratio is 392:208.

[0043] The preparation method of the above-mentioned anticorrosive liquid in this embodiment is basically the same as the preparation method of the anticorrosive liquid in Example 1, except that 392g mercaptopropyltrimethoxysilane, 208g tetraethoxysilane and 1000g ethanol are added The hydrolysis reaction is carried out in a flask equipped with a mechanical stirrer.

Example Embodiment

[0044] Example 3:

[0045] In this embodiment, the anti-corrosion liquid used on the surface of copper and copper alloys is basically the same as the anti-corrosion liquid in Example 1. The difference is: the quality of mercaptopropyltrimethoxysilane and tetraethoxysilane in this embodiment The ratio is 196:208.

[0046] The preparation method of the above-mentioned anticorrosive liquid in this embodiment is basically the same as the preparation method of the anticorrosive liquid in Example 1, except that 196g mercaptopropyltrimethoxysilane, 208g tetraethoxysilane and 1000g ethanol are added The hydrolysis reaction is carried out in a flask equipped with a mechanical stirrer.

Abstract

The invention discloses a preservative solution use for copper and a copper alloy surface, the preservative solution dissolves mercaptoalkyl alkoxy silane and alkoxy silane in an organic solvent, and a hydrolysis reaction is carried out under the catalytic effect of hydrolysis catalytic solution to obtain a hydrolysis product. Compared with the prior art, anticorrosive coatings formed by the preservative solution on copper and the copper alloy surface have good anticorrosive effect, scratch resistance performance and heat-resistant performance, and the preservative solution has excellent application prospect.

Description

technical field [0001] The invention belongs to the technical field of metal surface treatment, and in particular relates to an anticorrosion solution for copper and copper alloy surfaces, a preparation method and application thereof. Background technique [0002] Copper and copper alloys are widely used in various industries due to their good thermal conductivity, electrical conductivity, processability, mechanical properties, corrosion resistance and beautiful appearance. However, the corrosion of bare copper / copper alloys in strong corrosive environments such as moisture, acid-base, and electrolyte is a problem that cannot be ignored. In actual use, additional anti-corrosion measures must be applied to obtain good corrosion resistance. At present, electroplating / electroless plating, organic coating, and chromium passivation technology are commonly used anti-corrosion methods. These methods have their own advantages and disadvantages. For example, the electroplating layer...
