Embodiment 1

[0029] First, the corrosion inhibitor was prepared according to the weight ratio as follows: 84.9% water, 15% silica sol, 0.009% sodium molybdate, 0.09% triethanolamine, 0.001% vinyltriethoxysilane. well mixed. Next, soak the test board into the above solution, take it out after 1~3 minutes, and dry it at 60°C.

Embodiment 2

[0031] Referring to Example 1, replace "test board" with "decorative cover", and keep other conditions unchanged.

Embodiment 3

[0033] Referring to Example 1, replace "test board" with "pull-out faucet", and keep other conditions unchanged.

Abstract

The invention discloses a corrosion inhibitor and a using method thereof. The corrosion inhibitor is prepared from the following components including silica, oxygen-containing metal salt, a surfactant, organic siloxane and a solvent. The corrosion inhibitor does not contain toxic and harmful substances including chromate, nitrite and organic phosphine, and the metal surface subjected to coating treatment is good in corrosion resistance and finger resistant effect. The corrosion inhibitor is cheap, easily available, environmentally friendly and efficient as well as is simple and convenient in using method, good in stability and strong in practicability.

Description

technical field [0001] The invention belongs to the field of material surface treatment, and in particular relates to a corrosion inhibitor and a using method thereof. Background technique [0002] The surfaces of various products such as auto parts and kitchen and bathroom accessories are easily corroded and denatured due to frequent exposure to the air environment. Corrosion inhibitors are widely used as a material to delay product corrosion. Chromate and nitrite compounds are often added to the traditional corrosion inhibitor formula to enhance the effect. As proposed in patent applications 200610112446.9, 201210520050.3, 201210263670.3, etc. These corrosion inhibitors have good corrosion inhibition effects, but contain toxic and harmful substances, which seriously endanger the living environment and human health. Therefore, it is very important to develop environment-friendly corrosion inhibitors. [0003] The new environmentally friendly corrosion inhibitor does not...
