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. Salt and other carcinogens are very serious environmental pollution, and 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 harmful to the environment, the production process has low energy consumption, a

Embodiment 1

[0020] A metal surface silane treatment agent containing water-based nano-zinc oxide material, a mixed solution prepared from the following components, the parts by weight (grams) of each component in each liter of the mixed solution are:

[0021] Propyltrimethoxysilane 30, Aminopropyltriethoxysilane 40, Water-based Nano Zinc Oxide 200, Propylene Glycol 4, Zirconium Fluoride 4, Ethylene Glycol Monobutyl Ether 2, Sodium Monofluorophosphate 1, Ethylenediamine Sodium tetramethylene phosphonate 2, urea 2, acrylic acid 0.8, carboxymethyl cellulose 0.6, and the rest is water.

[0022] The preparation method of described aqueous nano zinc oxide material is:

[0023] (1) Ultrasonic disperse nano-zinc oxide in absolute ethanol 10 times its mass to obtain a dispersion, and then add 3% of its mass to dicumyl peroxide, 2% of vinyl tris(β-methoxy Ethoxy)silane was added to the above dispersion liquid, and reflux reaction was carried out at 90°C for 2 hours. After the reaction, a nano-zinc...

Abstract

The invention discloses a metal surface silane treating agent containing aqueous nano-zinc oxide. The metal surface silane treating agent is characterized by being a mixture solution prepared from the following ingredients in parts by weight (gram) in each liter of the mixture: 20-30 parts of propyl trimethoxy silane, 30-40 parts of aminopropyl triethoxy silane, 100-200 parts of aqueous nano-zinc oxide, 2-4 parts of propylene glycol, 2-4 parts of zirconium fluoride, 1-2 parts of ethylene glycol monobutyl ether, 0.8-1 parts of sodium monofluorophosphate, 2-3 parts of ethylene diamine tetramethylene risedremate sodium, 1-2 parts of urea, 0.6-0.8 parts of crylic acid, 0.4-0.6 parts of carboxymethyl cellulose and the balance of water. The metal surface silane treating agent has the advantages that a silane coating layer formed on the surface of a metal after the metal is treated by using the surface silane treating agent provided by the invention has excellent corrosion resistance performance, the service life of the metal is prolonged, and by combining the propyl trimethoxy silane and the aminopropyl triethoxy silane, a compact and solid coating layer is formed on the surface of the metal.

Description

technical field [0001] The invention mainly relates to a metal surface silane treatment agent and a preparation method thereof, in particular to a metal surface silane treatment agent containing aqueous nanometer zinc oxide material and a preparation method thereof. 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, and 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...
