Abstract
A sort of liquid used on metallic material and metalwork surface to protect against rustiness. It contains the following material: trisodium phosphate, sodium silicate, industrial sodium nitrite, methenamine, carbamide and water. It was used to enhance corrosion resistant capability of metal and to improve water-proof and air cutting-off capability of covering layer so that metal would show better and long-term effect against rustiness. Advantages are recyclable, non-pollution, safety and easiness to handle.
Description
Technical field
The invention belongs to field of metal surface treatment technology, is that pretreated metal rust-inhibiting liquid is carried out on a kind of surface to metallic substance and metal products.
Background technology
In technique known; to metallic substance and metal products generally after carrying out chemically treated degreasing and rust removal; can there be layer protecting film in the metallic surface; though this layer protective membrane can play certain antirust corrosion inhibition to metal in a short time; but generally remained to 3～5 days, new corrosion forms under protective film and development gradually.Therefore, how to make the surface of metallic substance can realize the antirust of long period, become a major subjects of current research.
Goal of the invention
The purpose of this invention is to provide a kind ofly, can prolong the antirust time, improve the metal rust-inhibiting liquid of rust-proof effect metallic substance behind the degreasing and rust removal or metal products.
Realize that the technical scheme that purpose of the present invention is taked is: this antirust tucking in is by following raw materials by weight percent: tertiary sodium phosphate 10～40%, water glass 0.5～3%, industrial sodium nitrite 3～9%, urotropine 0.5～3%, urea 4～9% and 40～70% water are formulated.During preparation,, according to a back order with last item mixed preparing, be hybridly prepared into rust protection liquid successively then earlier with each raw material aqueous solution work in-process raw material of making soluble in water respectively.
The present invention selects for use tri-sodium phosphate, water glass, industrial sodium nitrite, urotropine and urea to make up, and makes each raw material effect produce synergy, thereby can effectively prolong the metal rust preventing time, improves the metal rust preventing effect.The function of each raw material is respectively:
Tertiary sodium phosphate: be slightly acidic, have phosphatization, rust inhibition.
Water glass: be slightly acidic, can form oxide film, have anti-oxidation function.
Industrial sodium nitrite: be slightly acidic, have rust inhibition.
Urotropine: in raw material, play complexing action.
Urea: neutrality after above-mentioned raw materials mixes, has rust inhibition.
According to the formulated metal rust-inhibiting liquid of above-mentioned raw materials; be primarily aimed at the metal behind the degreasing and rust removal; after the immersion treatment of rust protection liquid of the present invention; can improve the sticking power of corrosion protection tunic at connection metal; and in formed protective membrane; the metallic surface can be caused the potential risk of corrosion be reduced to bottom line; also make simultaneously protective layer itself fine and close more; improve the erosion resistance of metallic surface; improve the performance of protective layer damp proof insulation and secluding air, make it have the rust-proof effect of reliable long period.Its rust-proof effect: generally can keep 2～3 months or can keep no longer producing about 1 year the secondary oxidation corrosion indoor outdoor.There is not the acid mist that can cause environmental pollution in the use of this rust protection liquid, can not cause the hydrogen embrittlement of metal yet, can skin ambustion during use, and non-stimulated, harmless to human body, safe and reliable, easy handling.
Embodiment
Metal rust-inhibiting liquid of the present invention is by following raw materials by weight percent: tertiary sodium phosphate 10～40%, water glass 0.5～3%, industrial sodium nitrite 3～9%, urotropine 0.5～3%, urea 4～9% and 40～70% water are formulated.
In the present invention, the consumption of each raw material is also groped to sum up to draw through the contriver in a large number, and its consumption all has effect preferably in the following weight percentage range.
Embodiment one
The weight percent of described each raw material is: tertiary sodium phosphate 20%, water glass 1%, industrial sodium nitrite 6%, urotropine 1%, urea 7%, surplus are water.
Embodiment two
The weight percent of described each raw material is: tertiary sodium phosphate 35%, water glass 2%, industrial sodium nitrite 4%, urotropine 2%, urea 5%, surplus are water.
Embodiment three
The weight percent of described each raw material is: tertiary sodium phosphate 15%, water glass 3%, industrial sodium nitrite 8%, urotropine 3%, urea 8%, surplus are water.
Compound method of the present invention: raw material is contained in the acid-resistant container by getting dosage respectively, and again that raw material is soluble in water respectively, the consumption of water is as the criterion can melt raw material, makes half-finished aqueous feed solution, and the melting temperature of each raw material and water is:
(1) tertiary sodium phosphate stirs with dissolving in 80～90 ℃ the hot water, makes trisodium phosphate aqueous solution, waits to join;
(2) water glass stirs with dissolving in 30～40 ℃ of warm water, makes sodium silicate aqueous solution, waits to join;
(3) industrial sodium nitrite stirs with dissolving in 30～40 ℃ of warm water, makes the industrial sodium nitrite aqueous solution, waits to join;
(4) urotropine stirs with dissolving in 30～40 ℃ of warm water, makes the urotropine aqueous solution, waits to join;
(5) urea stirs with dissolving in 30～40 ℃ of warm water, makes aqueous solution of urea, waits to join.
With the above-mentioned work in-process raw material to be joined of making the aqueous solution, according to a back order with last mixed preparing, mix successively and fill up the water yield by proportioning, be mixed with the metal rust-inhibiting liquid finished product, be contained in the plastic tank stand-by then.
Using method of the present invention is: only need build the pond that can heat, be contained with antirust working fluid in the pond, metal works is immersed in 40～50 ℃ the antirust working fluid, take out workpiece after 8～20 minutes, make liquid logical, metal works is immersed in 40～50 ℃ the antirust working fluid, take out workpiece after 8～20 minutes, at the ventilation airing, continue the nature phosphatization.This rust protection liquid can be recycled, and no discharging of waste liquid, its liquid ingredient be maintenance and control easily, and do not influence the metallic substance performance, and the phosphatize phosphate coat of formation does not have destruction to the application paint film.
Product of the present invention has good adaptive faculty and rust-proof effect, and easy to use, cost is low, less investment, efficient height, simultaneously to environment without any pollution.
