Description
Technical field
The present invention relates to the technical fields of bolt treatment process, more specifically, it relates to a kind of processing of antirust bolt
Technique.
Background technique
After bolt completes production in workshop, it will usually antirust treatment is carried out using antirust oil, to guarantee that it was being stored
Rustization will not be led to the problem of in journey.
Notification number is that the Chinese patent of CN103421393B discloses a kind of Rust prevention liquid for steel, and the antirust solution is by following component
It is formed according to weight ratio: 4 parts of dibutyl ethylene glycol ether, 12 parts of isopropyl myristate, 7 parts of calcium palmitate, triethanolamine oleate 5
Part, 6-8 parts of zinc naphthenate, 58-63 parts of rubber oil.
As long as this antirust solution ingredient is oils and Ester, it is relatively easy to occur to go bad, causes the antirust period shorter,
Have much room for improvement.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind for the treatment of process of antirust bolt, tool
Have the advantages that the antirust period long.
To achieve the above object, the present invention provides the following technical scheme that
A kind for the treatment of process of antirust bolt, includes the following steps,
S1, removing surface；
S2, surface passivation；
S3 coats antirust solution；
S4, drying；
According to parts by weight, the antirust solution includes following components:
20-25 parts of tertiary sodium phosphate；
2-5 parts of sodium metasilicate；

80-90 parts of water.
By using above-mentioned technical proposal, bolt surface is cleaned out first, to guarantee that bolt surface can be sufficiently blunt
Change, and then antirust solution is being coated to bolt surface, enables bolt that there is good rust-proof effect.
Tertiary sodium phosphate can form one layer of phosphating coat in bolt surface, to play anti-rust action.Sodium metasilicate then can be in spiral shell
The surface of bolt forms layer oxide film, plays anti-oxidation and antirust function.In the double protection of the oxidation film of phosphating coat
Under, can effective protection bolt, make it have good rustless property, and the antirust period is long.Methenamine is one kind to inhibit
Anodic corrosion inhibitor based on metal anode dissolution, can be improved the corrosion resistance of bolt, while methenamine can also play network
Cooperation is used, to improve oxidation film and phosphating coat in the adhesive force of bolt surface.In addition, the solution of tertiary sodium phosphate and sodium metasilicate is in
Acidity, enables to that methenamine decomposites a small amount of ammonia and formaldehyde is dissolved in antirust solution, and ammonia and formaldehyde have it is stronger
Reduction can effectively improve the storage of antirust solution.
2-mercaptobenzimidazole is otherwise known as antioxidant MB, has good antioxidant effect, can be improved the anti-of bolt
Rust-proof effect is aoxidized, and improves the storage of antirust solution.In addition, 2-mercaptobenzimidazole molecule head portion contains S atom function
Group, is easy to react with metal, therefore functional group-SH is main absorption point.Suction of the 2-mercaptobenzimidazole on the surface Fe
Attached position is mainly hollow absorption, and the d track that 2-mercaptobenzimidazole molecule loses electronics filling Fe in adsorption process forms coordination
Key.Meanwhile Fe provides electronics and 2-mercaptobenzimidazole molecular orbit hydridization, forms anti-coordinate bond, inhibits the electronics transfer of Fe,
To play good rust inhibition.
Further, according to parts by weight, the antirust solution includes 1-2 parts of phytic acid.
By using above-mentioned technical proposal, phytic acid is a kind of multiple tooth chelating agent of metal, it can form more in bolt surface
A chelate ring is adsorbed on metal surface, the erosion of atmospheric environment medium is hindered, to play rustless property.
Further, according to parts by weight, the antirust solution includes 0.05-0.1 parts of cerous nitrate.
By using above-mentioned technical proposal, cerous nitrate forms one layer of rare-earth oxide generally by bolt surface
Inhibit to corrode with hydroxide, due to the reduction reaction that the cathode reaction of metal erosion is oxygen, cathodic region pH value caused to increase,
Rare earth ion is deposited in cathode position in the form of hydroxide or oxide, hinders the progress of corrosion reaction.
In addition, cerous nitrate can also play synergy to the anti-rust action of phytic acid, to further increase rustless property.
Further, according to parts by weight, the antirust solution includes 3-4 parts of polyacrylic acid.
By using above-mentioned technical proposal, polyacrylic acid is a kind of chelating agent, can equally be formed and be chelated in bolt surface
To hinder the erosion of atmospheric environment medium, to play rustless property.Meanwhile polyacrylic acid has good emulsification and dispersion effect
Fruit can be improved dispersibility of each component in antirust liquid system, to improve antioxidant effect, guarantee to be also equipped with while antirust
Good storage.
Further, according to parts by weight, the antirust solution includes 0.5-1 parts of graphite powder.
By using above-mentioned technical proposal, graphite powder is capable of providing good greasy property, can be improved the use of bolt
Performance, while graphite powder can form a protective layer in bolt surface, to reduce connecing between bolt and atmospheric environment medium
Touching, to improve rust-proof effect.
Further, according to parts by weight, the antirust solution includes 1-3 parts of 4- morpholine phenyl boric acid.
By using above-mentioned technical proposal, 4- morpholine phenyl boric acid itself can provide good anti-rust action for bolt, this
Outside, 4- morpholine phenyl boric acid additionally aids antirust solution and forms a film in bolt surface, to guarantee rust-proof effect.
Further, the surface passivation is passivated processing to bolt surface using nitrite solution.
By using above-mentioned technical proposal, by nitrite to the Passivation Treatment of bolt surface, enable bolt surface
One layer of passivating film is formed, enough to improve its rust-proof effect.
In conclusion the invention has the following advantages:
1. tertiary sodium phosphate can form one layer of phosphating coat in bolt surface, to play anti-rust action.Sodium metasilicate then can be in bolt
Surface form layer oxide film, play anti-oxidation and antirust function.Under the double protection of the oxidation film of phosphating coat,
Can effective protection bolt, make it have good rustless property, and the antirust period is long.Methenamine is one kind to inhibit metal
Anodic corrosion inhibitor based on anodic solution can be improved the corrosion resistance of bolt, while methenamine can also play complexing and make
With to improve oxidation film and phosphating coat in the adhesive force of bolt surface.In addition, the solution of tertiary sodium phosphate and sodium metasilicate is in acid
Property, enable to that methenamine decomposites a small amount of ammonia and formaldehyde is dissolved in antirust solution, and ammonia and formaldehyde have it is stronger also
Original work are used, and the storage of antirust solution can be effectively improved.
The antioxidant MB 2. 2-mercaptobenzimidazole is otherwise known as has good antioxidant effect, can be improved bolt
Anti-oxidant rust-proof effect, and improve the storage of antirust solution.In addition, 2-mercaptobenzimidazole molecule head portion contains S atom official
It can roll into a ball, be easy to react with metal, therefore functional group-SH is main absorption point.2-mercaptobenzimidazole is on the surface Fe
Adsorption potential is mainly hollow absorption, and the d track formation that 2-mercaptobenzimidazole molecule loses electronics filling Fe in adsorption process is matched
Position key.Meanwhile Fe provides electronics and 2-mercaptobenzimidazole molecular orbit hydridization, forms anti-coordinate bond, and the electronics of Fe is inhibited to turn
It moves, to play good rust inhibition.
3. cerous nitrate inhibits rotten generally by one layer of rare-earth oxide and hydroxide is formed in bolt surface
Erosion causes cathodic region pH value to increase, rare earth ion is with hydrogen-oxygen due to the reduction reaction that the cathode reaction of metal erosion is oxygen
Compound or the form of oxide are deposited in cathode position, hinder the progress of corrosion reaction.In addition, cerous nitrate can also be to phytic acid
Anti-rust action plays synergy, to further increase rustless property.
