Description

A kind of metal antirusting agent that contains paregal O

Technical field

The present invention relates to the rust-preventive agent field, exactly is a kind of metal antirusting agent that contains paregal O.

Background technology

Water-based antirust agent is a kind of aqueous rustproof solution, can effectively protect the materials such as steel, iron, prevents from getting rusty.The difference that requires according to rust-proof life, and water the antirust time limit can reach several days to several months than mixing use by certain, if certain outer packaging condition is arranged, the antirust time can reach more than 1 year.The existing many rustless properties of 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 realizes by following scheme:

A kind of metal antirusting agent that contains paregal O is characterized in that: it is that raw material by following weight parts makes: urea 2-5, liquefied petrolatum 5-8, tri(2-ethylhexyl)acetocitrate 3-5, vinylformic acid 4-6, zinc powder 0.2-0.3, nontoxic plasticizer 3-5, dimethylbenzene 2-3, polyethylene wax 3-5, Potassium Persulphate 0.2-0.3, borax 0.3-0.5, zinc naphthenate 1-2,2-Methylimidazole quinoline 0.5-0.9, benzotriazole 1.3-1.5, urotropine 0.5-1.5, di-n-octyl-4-isothiazolinone 1.1-1.7, paregal O 1.2-1.9, water 95-105.

Described a kind of metal antirusting agent that contains paregal O, it is characterized in that: the preparation method may further comprise the steps:

(1) by weight liquefied petrolatum, tri(2-ethylhexyl)acetocitrate, vinylformic acid, nontoxic plasticizer, dimethylbenzene, polyethylene wax are added stainless steel cauldron, be warming up to 110 ± 5 ℃, begin to stir and add by weight urea, Potassium Persulphate, borax, zinc powder;

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

(3) 1-2 hour stopped heating of reaction;

(4) will add by weight surplus stock and add stainless steel cauldron, after the mixing dissolving and get final product.

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 preferably adaptability, when the present invention is can slowly-releasing antirust in the metallic surface film forming, thereby prolong the antirust time.The adding of paregal O can be played the effect of removing metal surface greasy dirt, also plays simultaneously the effect that improves stability of the present invention.

Embodiment

A kind of metal antirusting agent that contains paregal O, it is that raw material by following weight parts (kg) makes: urea 3, liquefied petrolatum 6, tri(2-ethylhexyl)acetocitrate 4, vinylformic acid 5, zinc powder 0.2, nontoxic plasticizer 4, dimethylbenzene 2, polyethylene wax 4, Potassium Persulphate 0.2, borax 0.3, zinc naphthenate 1,2-Methylimidazole quinoline 0.7, benzotriazole 1.4, urotropine 1.1, di-n-octyl-4-isothiazolinone 1.4, paregal O 1.4, water 95.

Described a kind of metal antirusting agent that contains paregal O, the preparation method may further comprise the steps:

(1) by weight liquefied petrolatum, tri(2-ethylhexyl)acetocitrate, vinylformic acid, nontoxic plasticizer, dimethylbenzene, polyethylene wax are added stainless steel cauldron, be warming up to 110 ℃, begin to stir and add by weight urea, Potassium Persulphate, borax, zinc powder;

(2) then be warmed up to 185 ℃ with 60 ℃ of/hour speed;

(3) 2 hours stopped heatings of reaction;

(4) will add by weight surplus stock and add stainless steel cauldron, after the mixing dissolving and get final product.

Present embodiment and commercially available domestic rust-preventive agent are compared experiment, and wherein property indices is measured respectively as follows:

High low temperature stability test: carry out according to JB/T4323.2-1999.

Damp and hot rust prevention test: the test piece of one-level grey cast iron is soaked 1min in 50～70 ℃ rust protection liquid, take out oven dry (110 ℃), test piece is put on the dividing plate of moisture eliminator (500～1000ml distilled water is injected in the bottom), add a cover and be placed on constant temperature placement under 35 ℃ ± 2 ℃ conditions, observe the antirust time.

Corrosion test: carry out according to JB/T4323.2-1999.

Indoor hanging test: the test piece of one-level grey cast iron hangs up indoor after antirust processing, observes test piece surface corrosion situation.

Seal rust prevention test up for safekeeping: after the antirust processing of one-level grey cast iron test piece, transparent sealed plastic bag is put in test piece, the surface appearance of good seal routine observation test piece.

Measurement result sees Table one:

Table one

As shown in Table 1, the anti-embroidery time of the present invention is long, can reach 4～6 months, and copper, aluminium are had preferably adaptability.Pass through simultaneously compatibility test, the consistency of present embodiment and each material is good, can't affect the normal operation of parts.
