Resistance to pesticide corrosivity have better optimization function；Reference examples 1 to reference examples 2 do not add poly- butylaniline nanofiber and nitrogen
SiClx powder, anti-corrosion effect are decreased obviously, and illustrate that poly- butylaniline nanofiber and the modified of silicon nitride powder foot couple coating generate
Great influence；Reference examples 3 change polyamide 6 50 and dimethylbenzene proportion to reference examples 4, and effect is also bad, and it is de- that blistering occurs in coating
It falls；Reference examples 5 to reference examples 6 do not add cobalt nitrate hexahydrate Co(NO3)2·6H2O is simultaneously replaced, anti-corrosion effect with five water copper nitrates
It is substantially reduced, illustrates that cobalt nitrate hexahydrate is very big to the compound influence of nanofiller structure；Reference examples 7 to reference examples 8 change six water
Cobalt nitrate and 2-methylimidazole proportion, the corrosion resistance of coating are obviously deteriorated, and effect is still bad；Reference examples 9 and reference examples 10
Do not add calcium carbonate it is compound and with sodium carbonate replace calcium carbonate, effect is still bad, illustrates that the compound of calcium carbonate fills out nanometer
The modification of material has great influence；Therefore there is good acid-alkali-corrosive-resisting effect using corrosion-resistant finishes of the present invention.
