(2) then with 50-60 ℃/h of speed, be warmed up to 180-195 ℃;

(3) reaction stops heating for 1-2 hour;

(4) will add by weight surplus stock to add reactor, after mixing dissolving and get final product;

Described surplus stock is the component of following weight parts: polyisobutene 0.8-1.6, phenylformic acid amine 1-2,2-Methylimidazole quinoline 0.7-1.2, N-phenyl-2-naphthylamine 0.9-1.7, zinc dialkyl dithiophosphate 1-2, styrylphenol polyoxyethylene ether 1-2, polyoxyethylene glycol 1-2, propylene glycol 2-3, water 100-105.

The preparation method of described a kind of metal antirusting agent that contains styrylphenol polyoxyethylene ether, is characterized in that: described reactor is stainless steel cauldron.

Beneficial effect of the present invention is: the consistency of the present invention and each material is good, and the antirust time is long, can reach 4-6 month, and copper, aluminum are had to good adaptability, when the present invention is can slowly-releasing antirust in metallic surface film forming, thereby extend the antirust time.
