Embodiment 1

[0021] Add silane to pure water until the hydrolysis is complete, then add anti-rust metal salt, resin, paint additive, pH regulator in sequence, and mix evenly to obtain an environmentally friendly galvanized steel passivation treatment agent product.

[0022] The consumption (percentage by weight) of above-mentioned each component is:

[0023] Silane 8.5%

[0024] Anti-rust metal salt 2%

[0025] Resin 18%

[0026] Paint Additive 0.5%

[0027] pH regulator 1%

[0028] Water 70%.

[0029] Silane is N-(2-aminoethyl)-3-aminopropylmethyldimethoxysilane [or 2-(3,4-epoxycyclohexyl)ethyltrimethoxysilane, 3-glycidyl ether propylmethyldimethoxysilane, 3-glycidyl ether propyltrimethoxysilane, 3-aminopropyltriethoxysilane, N-(2-aminoethyl)-3-aminopropyl One or more of trimethoxysilane].

[0030] Anti-rust metal salt is metal manganese sulfate (or one or more of the salts of magnesium, nickel, molybdenum, tungsten, hafnium, aluminum, zirconium, tin, titanium, cesium, boron, vanad...

Embodiment 2

[0035] The weight percent of each component is:

[0036] Silane 18%

[0037] Anti-rust metal salt 1%

[0038] Resin 10%

[0039] Paint Additives 3%

[0040] pH regulator 4%

[0041] Water 64%.

[0042] All the other are with embodiment 1.

Embodiment 3

[0044] The weight percent of each component is:

[0045] Silane 5%

[0046] Anti-rust metal salt 4%

[0047] Resin 20%

[0048] Paint Additives 5%

[0049] pH regulator 5%

[0050] Water 61%.

[0051] All the other are with embodiment 1.

Abstract

The invention discloses a passivating treating agent for environment-friendly galvanized steel sheets, which is composed of 2-20% of silane, 1-5% of anti-rusting metal salt, 8-20% of resin, 0.1-5% of coating additive, 0.5-5% of pH regulating agent and 50-70% of water. The passivating treating agent features in simple and convenient preparation process and mainly depends on mixing production; drying temperature thereof is as low as 50-60 DEG C, in 96 hours, salt mist resistance property is no more than 3% and performance thereof is good.

Description

Technical field: [0001] The invention relates to a passivation treatment agent for galvanized steel sheets. Background technique: [0002] The existing treatment agent for galvanized steel sheet has complex production process, short storage period, high drying temperature (70-80°C), unsatisfactory work performance, and its resistance to salt spray test performance is not more than 5% in 96 hours. Invention content: [0003] The object of the present invention is to provide an environment-friendly passivation treatment agent for galvanized steel sheets which is easy to produce and has good working performance. [0004] Technical solution of the present invention is: [0005] An environment-friendly galvanized steel plate passivation treatment agent is characterized in that: it is composed of the following components by weight percentage: [0006] Silane 2~20% [0007] Anti-rust metal salt 1~5% [0008] Resin 8~20% [0009] Paint additive 0.1~5% [0010] pH adjuster 0....
