Abstract
The invention discloses a metal antirust agent having a long antirust time and containing sodium diacetate. The metal antirust agent is prepared from the following raw materials, by weight, 2-5 parts of urea, 7-9 parts of liquefied paraffin, 3-5 parts of tri(2-ethylhexyl)acetocitrate, 3-5 parts of acrylic acid, 0.2-0.3 parts of zinc powder, 3-5 parts of epoxy linseed oil, 2-3 parts of xylene, 3-5 parts of polyethylene wax, 0.2-0.3 parts of potassium persulphate, 0.3-0.5 parts of borax, 1-2 parts of polyisobutylene, 0.6-1.2 parts of ammonium molybdate, 1.2-1.8 parts of sodium diacetate, 1.2-1.9 parts of 2-methylimidazoline, 0.9-1.6 parts of diethanolamine, 1-2 parts of polyoxyethylene nonyl phenyl ether, 0.8-1.6 parts of polydimethylsiloxane and 95-105 parts of water. The metal antirust agent has a long antirust time which can reach 3-6 months, can well adapt to copper and aluminum, and simultaneously forms a film on the metal surface when the corrosion and rust inhibition of the metal antirust agent is carried out, so the antirust time is prolonged.
Description
Technical field
The present invention relates to rust-preventive agent field, is exactly the metal antirusting agent containing sodium Diacetate that a kind of antirust time is long.
Background technology
Water-based antirust agent is a kind of aqueous rustproof solution, can effectively protect the material such as steel, iron, prevent from getting rusty.According to the difference that rust-proof life requires, and water is pressed certain for used in combination, and the antirust time limit can reach several days to several months, if there is certain outer packaging condition, antirust time can reach more than 1 year.The many rustless properties of existing rust-preventive agent are not good, are badly in need of a kind of metal antirusting agent of good antirust property.
Summary of the invention
The object of the present invention is to provide a kind of metal antirusting agent of good antirust property.
Above-mentioned purpose is realized by following scheme:
The metal antirusting agent containing sodium Diacetate that a kind of antirust time is long, it is characterized in that: it is obtained by the raw material of following weight parts: urea 2-5, liquefied petrolatum 7-9, tri(2-ethylhexyl)acetocitrate 3-5, vinylformic acid 3-5, zinc powder 0.2-0.3, epoxidized linseed oil 3-5, dimethylbenzene 2-3, polyethylene wax 3-5, Potassium Persulphate 0.2-0.3, borax 0.3-0.5, polyisobutene 1-2, ammonium molybdate 0.6-1.2, sodium Diacetate 1.2-1.8, 2-Methylimidazole quinoline 1.2-1.9, diethanolamine 0.9-1.6, polyoxyethylene nonylphenol ether 1-2, polydimethylsiloxane 0.8-1.6, water 95-105.
The metal antirusting agent containing sodium Diacetate that described a kind of antirust time is long, is characterized in that: preparation method comprises the following steps:
(1) by weight liquefied petrolatum, tri(2-ethylhexyl)acetocitrate, vinylformic acid, epoxidized linseed oil, dimethylbenzene, polyethylene wax are added stainless steel cauldron, be warming up to 110 ± 5 DEG C, start stir and add urea, Potassium Persulphate, borax, zinc powder by weight;
(2) then with 50-60 DEG C/h of ramp to 180-195 DEG C;
(3) react and stop heating in 1-2 hour;
(4) surplus stock will be added by weight and add stainless steel cauldron, and mix after dissolving and get final product.
Beneficial effect of the present invention is: the consistency of the present invention and each material is good, and antirust time is long, can reach 3-6 month, and have good adaptability to copper, aluminum, the present invention can slowly-releasing antirust while in metallic surface film forming, thus extend antirust time.
Embodiment
