Embodiment 1

[0017] A salt spray resistant metal surface silane treatment agent, which is a mixed liquid prepared by the following components, and the weight parts (grams) of each component in each liter of the mixed liquid are:

[0018] Propyl trimethoxysilane 25-30, vinyl trimethoxysilane 15-25, sodium hexametaphosphate 4-5, tetrahydrofuran 1-2, hexamethylphosphoric triamide 5-7, citric acid 3-4, Sorbitol 6-7, film-forming aids 2-4, the rest is water;

[0019] The said film-forming assistant is composed of the following raw materials in parts by weight:

[0020] 1,2-bis(triethoxysilyl)ethane 6, diethylene glycol monobutyl ether 5, acrylic acid 6, sodium metasilicate 2, alum 2, water 20;

[0021] Add the above-mentioned 1,2-bis(triethoxysilyl)ethane to water, stir and heat to 80°C, add acrylic acid and sodium metasilicate, stir and react for 40 minutes, raise the temperature to 100°C, add two Ethylene glycol monobutyl ether and alum were stirred and reacted for 20 minutes, and kept standing for ...

Abstract

The invention discloses a salt spray resistant metal surface silane treatment agent, which is a mixed solution prepared from the following components. Per liter of the mixed solution comprises the following components by weight (g): 25-30 of propyltrimethoxy silane, 15-25 of vinyltrimethoxy silane, 4-5 of sodium hexametaphosphate, 1-2 of tetrahydrofuran, 5-7 of hexamethylphosphoric triamide, 3-4 of citric acid, 6-7 of sorbitol, 2-4 of a film-forming agent, and the balance water. The treatment process of the salt spray resistant metal surface silane treatment agent produced in the invention generates no dreg, the treatment time is short, and the control is simple and convenient. Being free of harmful heavy metal ions, the salt spray resistant metal surface silane treatment agent is safe and environment-friendly, and can form a silane coating having excellent corrosion resistance with a metal surface, thus prolonging the service life of metals.

Description

Technical field [0001] The invention mainly relates to a treatment agent, in particular to a metal surface silane treatment agent resistant to salt spray. Background technique [0002] With the maturity of metal surface treatment technology, traditional phosphate conversion and chromate passivation surface treatment technologies have gradually been replaced by environmentally friendly and energy-saving silanization treatment technologies due to environmental pollution and easy harm to the human body. However, the current silane Most chemical treatments rely solely on the film-forming properties of silane, so that the film formed on the surface of the metal workpiece treated with the silane solution has uneven density, voids, cracks, and weak adhesion to the metal body. Summary of the invention [0003] The purpose of the present invention is to make up for the defects of the prior art and provide a salt spray resistant metal surface silane treatment agent and a preparation...
