Abstract
The invention relates to a passivant, characterized in the passivant comprises: 5 parts to 15 parts by weight of fast preservative, 0.5 parts to 3 parts by weight of methenamine, 10 parts to 30 parts by weight of quicklime or industrial alkali and the balance water. The invention has the advantages of: 1. good descaling effect: the passivated steel appearing its true color, silvery and shining, and expanding secondary descaling time; 2. non-toxicity, harmfulness and environment friendly; 3. operation simplicity, lowering enterprise use cost; and 4. low production cost: the sale price of the invention being 50% of that of similar products.
Description
Technical field:
The present invention relates to a kind of metal conditioner, particularly a kind of passivator that prevents that the metallic surface from getting rusty.
Background technology:
Metal level is antirust to be very important work of metal-processing industry, in recent years, for fear of rust corrosion, the development of rust-preventive agent and antirust technology also is with rapid changepl. never-ending changes and improvements, present most of enterprise still uses traditional technology to carry out phosphatization, and there is following defective in this technology: 1, in the process of using phosphatization liquid, the temperature of phosphatization liquid need be heated to more than 60 ℃.Therefore 2, cannot recycle, just strengthen quantity discharged, and wherein contain countries such as phosphorus, heavy metal and forbid the objectionable impurities of discharging causing environmental pollution.3, phosphatization liquid in use can produce sharp aroma and smog, causes the infringement of human body skin easily.4, use the operating procedure of phosphatization liquid loaded down with trivial details, generally will pass through steps such as neutralization, washing, surperficial adjustment, washing, phosphatization, washing, passivation (saponification), washing, therefore make the production cost of enterprise improve.
Summary of the invention:
Purpose of the present invention just is to overcome above-mentioned the deficiencies in the prior art, and provide a kind of passivator, this passivator is nontoxic, harmless, environmental protection, seepage force and raising be coated with cross a layer sticking power, simple to operate, production cost is low, can realize rust inhibition well.
Technical scheme of the present invention is: a kind of passivator is characterized in that: made according to following weight proportion by following raw materials according: quick sanitas 5-15 part, urotropine 0.5-3 part, unslaked lime or industrial soda 10-30 part, all the other are water.
The quick sanitas of above-mentioned raw materials can adopt trolamine, and weight proportion is trolamine 5-15 part, urotropine 1-3 part, industrial soda 5-30 part.
The quick sanitas of above-mentioned raw materials can adopt phenylformic acid to receive, and the weight proportion that can add sodium dodecyl benzenylsulfonate 0.5-2 part and other raw material in the raw material is that phenylformic acid is received 4-8 part, urotropine 0.5-2 part, unslaked lime 10-30 part, and all the other are water.
Also can add urea 1-5 part, unslaked lime 5-15 part in the above-mentioned raw materials again.
Preparation principle of the present invention is: use industrial soda and unslaked lime and the steel surface after the rust cleaning is played neutralizing effect, be neutral, thereby reach rust-proof effect.But use various raw materials in the sodium dodecyl benzenylsulfonate activating recipe, make it give full play to usefulness.Use urotropine can make the passive film of formation even, consistent.Use urea can quicken the formation of passive film, shorten passivation time and effect.Use phenylformic acid to receive and play anticorrosion, rust inhibition.
The present invention has following advantage and positively effect:
1, passivation favorable rust preventing effect.Steel surface after the passivation presents the true colours of steel, the silver color light, and can prolong secondary and get rusty the time.
2, nontoxic, harmless, environmental protection.1. in use without any sharp aroma and smog, harmless to human body skin.2. can use at normal temperatures, need not heat.3. can be recycled, add repeatedly, so just reduced discharging widely, and do not contain countries such as phosphorus, heavy metal among the present invention and forbid in the time must discharging, mixing the objectionable impurities of discharging, discharge again after being neutralized to neutrality with the rust remover waste liquid.
3, simple to operate, can reduce enterprise's use cost.Use the present invention can finish just once that neutralization, surface are adjusted, passive film formation technology, after the passivation without clean surface.Compare with traditional technology and not only to save a large amount of rinse water, also can reduce a large amount of operating procedures.
4, production cost is low, and selling price of the present invention is 50% of a like product.
Embodiment:
Embodiment 1: a kind of passivator, made according to following weight proportion by following raw materials according: phenylformic acid is received 6 kilograms, 1 kilogram of sodium dodecyl benzenylsulfonate, 2 kilograms of urotropines, 20 kilograms of unslaked limes, and all the other are water.
Embodiment 2: in order to quicken the formation of passive film, shorten passivation time and effect, add 3 kilograms in urea, 10 kilograms of unslaked limes again in the prescription of embodiment 1, surplus is a water.
Embodiment 3: in order further to accelerate to quicken the formation of passive film, shorten passivation time and effect, make blunt colored film more firm, prolong the antirust time of secondary, add 10 kilograms of trolamines, 2 kilograms of urotropines, 20 kilograms of industrial soda again, surplus is a water.
Claims (4)
1. passivator is characterized in that: made according to following weight proportion by following raw materials according: sanitas 5-15 part, urotropine 0.5-3 part, unslaked lime or industrial soda 10-30 part fast, all the other are water.
2. the passivator used according to claim 1 is characterized in that: the quick sanitas of above-mentioned raw materials can adopt trolamine, and weight proportion is trolamine 5-15 part, urotropine 1-3 part, industrial soda 5-30 part.
3. the passivator used according to claim 1, it is characterized in that: the quick sanitas of above-mentioned raw materials can adopt phenylformic acid to receive, and the weight proportion that can add sodium dodecyl benzenylsulfonate 0.5-2 part and other raw material in the raw material is that phenylformic acid is received 4-8 part, urotropine 0.5-2 part, unslaked lime 10-30 part, and all the other are water.
