Description
Technical field
The present invention relates to steel structure technology fields, particularly belong to a kind of steel construction piece anti-corrosive treatment method.
Background technology
Due to structural steel intensity height, plasticity good toughness, from heavy and light, in addition steel construction has the simple for production, construction period
It is short, it is suitable for the advantages that span is big, height is high, the structure of carrying weight, steel is made to be widely applied in construction industry.
But corrosion resistance of steel and rust resistance are poor, according to the incomplete statistics of developed country, every year since corrosion causes
Economic loss account for about the 4% of total value of production in national economy.The corrosion of steel construction not only causes economic loss, also gives the safety of structure
Hidden danger is brought, engineering accident is also commonplace caused by steel corrosion.Therefore steel construction (especially thin-walled steel member)
Preservative treatment has important economy and social effect.
Invention content
The object of the present invention is to provide a kind of steel construction piece anti-corrosive treatment methods, overcome the deficiencies in the prior art,
Steel construction piece surface is attached with oxide layer and protective layer successively, is handled using Double-protection, it is anti-corrosion to improve steel construction piece
Erosion ability.
To solve the above problems, the technical solution used in the present invention is as follows：
A kind of steel construction piece anti-corrosive treatment method, includes the following steps：
Step 1, pretreatment：The steel construction piece is processed by shot blasting, steel construction piece is then suspended on degreasant solution
In, it allows degreasant solution freely to be circulated on steel construction piece surface, is finally rinsed and dried with clear water；
Step 2, overlay film：By step 1, treated that steel construction piece is placed in lives sodium nitrite solution containing caustic soda, sodium nitrate
In, after air drying a kind of oxidation film of black is formed on steel construction piece surface；
Step 3 sprays composite protective coating：Composite protective coating, drying are sprayed to step 2 treated steel construction piece
Protective layer is formed outside oxidation film layer afterwards to get to anti-corrosion steel structural member.
Further, the composite protective coating is by priming paint, and intermediate coat, finishing coat composition, the priming paint is epoxy zinc rich primer,
The intermediate coat is epoxy micaceous iron intermediate coat, and the finishing coat is chlorinated rubber finish.
Further, the primer 1 time, the intermediate coat paint are smeared 2 times, and the finishing coat is smeared 2 times.
Further, the degreasant solution is thermokalite degreasant solution, and temperature is 80 DEG C.
Compared with prior art, implementation result of the invention is as follows by the present invention：
A kind of steel construction piece anti-corrosive treatment method of the present invention, by steel construction piece surface be attached with successively oxide layer and
Protective layer is handled using Double-protection, improves the anti-corrosion erosion ability of steel construction piece, using epoxy zinc rich primer not only anti-corrosive properties
Can be excellent, and strong adhesive force, and have good binding type with lower road coating epoxy micaceous iron intermediate layer paint, while using chlorination
Rubberbase paint category inert plastic, sealing performance is very good after film forming, and steam, oxygen are extremely low to the permeability of paint film, greatly improves
Corrosion resistance, extends steel construction piece service life.
