Thinner of the present invention includes toluene, dimethylbenzene and high aromatic hydrocarbon, and is at least wherein a kind of, certainly, also can select identical or proximate other thinner of character for use.
Antisettling agent of the present invention includes wilkinite and thixotroping flow agent, and is at least wherein a kind of, certainly, also can select identical or proximate other antisettling agent of character for use.
Dispersion agent of the present invention includes organo silane coupling agent (KH550) and diethyl diallyl ammonium chloride (3270), and is at least wherein a kind of, certainly, also can select identical or proximate other dispersion agent of character for use.
Ionic surfactant pack of the present invention has been drawn together OP10, certainly, also can select identical or proximate other nonionogenic tenside of character for use.
The mentioned above-mentioned additive of the present invention all can be bought from the market.
This Zinc-aluminum composite plating coating making method that the present invention provides is made up of the following step:
During (1) as if employing superfine sheet dryness zinc powder, superfine sheet dryness aluminium powder, add thinner, its ratio is 2: 1: 2 (ratio of weight and number), and wetting normal temperature and pressure conditions soaked 24 hours down, mixing and stirring;
During (2) as if employing superfine sheet solvent-borne type zinc powder slurry (solids content 60-70%) and superfine sheet solvent-borne type aluminum paste (solids content 60-70%), then starch: the ratio of aluminum paste=2: 1 (ratio of weight and number) in zinc powder, directly add thinner 1.5 ratios of weight and number again, mixing and stirring;
(3) superfine laminar zinc powder and the aluminium powder powder that will dilute the back mixing and stirring again under normal temperature and pressure conditions starched and the resinene mixing and stirring, add antisettling agent, dispersion agent, nonionogenic tenside again, stir once more, obtain the finished product Zinc-aluminum composite plating coating at last.
Numerical result after this Zinc-aluminum composite plating coating that the present invention provides detects by analysis is as follows:
| Sequence number | Test item | Detected result |
| 1 | Neutral salt spray test | Red rust did not appear in 400 hours |
| 2 | The paint film cross cut test | Edge-smoothing does not have and comes off 0 grade |
| 3 | Shock test | Coating is complete, and shock resistance is qualified |
| 4 | Solids content % | 54 |
Compared with prior art, beneficial effect of the present invention is: metal content is below 60% in the dry film, under the condition of coat-thickness 40um, still can satisfy the requirement of metal heavy-duty, saved the usage quantity of metal in coating, thereby the coat-thickness that has solved conventional heavy-duty coating is big, metal content is high, surface color is not good, to problem such as gas phase liquid phase medium sealing effect is not good.
