Embodiment 1
[0021] A metal surface silane treatment agent containing diethanolamine is a mixed solution prepared from the following components, and the parts by weight (grams) of each component in each liter of the mixed solution are:
[0022] 1,2-bis(triethoxysilyl)ethane 35, γ-aminopropyltriethoxysilane 40, water-based nano zinc oxide material 160, propenyl alcohol 3, ethylene glycol 2, sodium tripolyphosphate 3 , propylene glycol 4, zirconium tetrafluoride 3, diethanolamine 3, ammonium chloride 3, diethylene glycol butyl ether 2, trimethylolpropane 2, sodium dodecylbenzenesulfonate 0.5, and the rest is water;
[0023] The preparation method of described aqueous nano zinc oxide material is:
[0024] (1) Ultrasonic disperse nano-zinc oxide in absolute ethanol 5 times its mass to obtain a dispersion, and then add 4% of its mass of dicumyl peroxide and 2% of anilinomethyltriethoxysilane In the above dispersion liquid, reflux reaction at 90°C for 2 hours, after the reaction, a nano-zinc ox...
