The water solution is used instead of the organic volatile solvent, thereby maximally lowering the environmental pollution.

Description

The agent of a kind of Surface Rust of Weathering Steel stabilization treatment
Technical field
The invention belongs to ferrous materials anticorrosion technique field, particularly a kind of Surface Rust of Weathering Steel stabilization treatment agent.
Background technology
Weathering steel can generate fine and close protective rust due to its surface, relative to carbon steel, has very good atmospheric corrosion resistance ability.In Practical Project, weathering steel application can be divided three classes: (1) exposed use; (2) application uses; (3) use after surface treatment.But in its natural state, exposed weathering steel surface production stablizes the time that rusty scale needs about 10 years, and, often there is the reversal of the natural order of things of rust liquid at the use initial stage and disperse phenomenon, contaminate environment.At some salinities and S0 2the regional weathering steel surface-stable rusty scale of too high levels is difficult to be formed, and weathering steel uses must carry out application in these areas, this adds increased the maintenance cost in use cost and later stage.
In order to solve, weathering steel is exposed uses the problems referred to above produced, Japanese scholars has done a large amount of development and research in Surface Rust of Weathering Steel stabilizing surface treatment, this technology implemented a kind of process, to shorten the forming process of weathering steel surface-stable rusty scale to its component surface before weathering steel uses.The phenomenon that it both can avoid weathering steel to use initial stage rust liquid reversal of the natural order of things and disperse, can form again the protection rusty scale that energy is fine and close fast.At present, the weathering steel process of surface treatment abroad carried out has weathering resistance technology for coating, oxide coating technology and band rust coating N process and novel surface treatment agent (namely in polyvinyl butyral resin, to add a certain amount of chromium sulphate, make surface compound treatment agent, on weather resisting steel surface, directly coating 15-20 μm is thick, the interface of film and steel reacts, and makes steel Surface Creation stablize rusty scale at short notice) etc.In addition, CUPTENCOATM process for treating surface newly developed in the recent period stablizes the generation of rusty scale under promoting high salinity atmospheric environment, avoids rust liquid sagging phenomenon.Domestic many scientific research institutions at present also all in the research carrying out Surface Rust of Weathering Steel stabilizing surface treatment, but also untapped go out the more ripe treatment technology being widely used in stable weathering steel component surface rustization layer.
The open notification number of patent of invention is a kind of surface stabilizing treatment agent for weathering-resistant steel of CN102268663, and its main component comprises host, assistant agent, properties-correcting agent, rust inhibitor etc., and solvent is ethanol.In this invention, etoh solvent is volatile matter, and treatment agent volatilizees and to have a negative impact to its application in preparation and use procedure.
The open notification number of patent of invention is that a kind of of CN103556143 generates the stable hydrojet of rusty scale with iron scale steel, and its main component comprises FeSO 4, CuSO 4, NaHSO 3, Na 2siO 3, Weibull, solvent is water.This invention treatment agent can be sprayed on the surface of steel plate of band iron scale, but needs repeatedly to repeat spraying, and time of drying is longer.
Exempt to be coated be contained in applying in the Practical Project such as bridge, motorway to realize weathering steel as early as possible, need a kind of novel Surface Rust of Weathering Steel stabilizing surface treatment badly.
Summary of the invention
The object of the present invention is to provide the agent of a kind of Surface Rust of Weathering Steel stabilization treatment, solve current weathering steel and exempt from application and apply the Surface Rust stabilizing surface treatment problem run into.Realize one based on water soluble acrylic resin, water is solvent, adds the novel weathering resistant steel Surface Rust stablizer of the pigment such as chromium sulphate, ferric oxide.
The agent of a kind of Surface Rust of Weathering Steel stabilization treatment, each component is by mass percentage: water soluble acrylic resin's liquid: 40%-50%, chromium sulphate: 0.1%-2%, Fe 2o 3: 1%-5%, Fe 3o 4: 0.5%-3%, polyoxyethylene glycol: 0.01%-0.1%, defoamer: 0.01%-0.1%, wetting agent: 0.01%-0.1%, all the other are water.
The method of the invention specifically comprises the steps:
Step 1: steel plate is removed scale on surface by shot-peening or pickling.
Step 2: mass percent is 40%-50% water soluble acrylic resin liquid, 0.1%-2% chromium sulphate, 1%-5%Fe by preparation Surface Rust stablizer 2o 3, 0.5%-3%Fe 3o 4, 0.01%-0.1% polyoxyethylene glycol, 0.01%-0.1% defoamer, 0.01%-0.1% wetting agent mix with water, put into after container stirs and obtain rusty scale stablizer, solution is chocolate.
Step 3: rusty scale stabiliser solution is evenly brushed at surface of steel plate with hairbrush, air-dry 15-25min under room temperature.
In Surface Rust of Weathering Steel stablizer of the present invention, water soluble acrylic resin is film forming main body, chromium sulphate, Fe 2o 3the generation of alpha-feooh can be promoted, Fe 3o 4play toning effect, polyoxyethylene glycol, defoamer and wetting agent promote dissolution homogeneity mixing, but add-on is too much unsuitable, adds excessive meeting and causes solution overall flow to reduce, and are unfavorable for coating.
The invention has the advantages that: instead of organic volatile solvent with the aqueous solution, thus reduce the pollution to environment to greatest extent, and after coating, time of drying is short, implementing process is simple, can be widely used in the Steel Structure Works such as bridge, building, electric tower.

Embodiment
Embodiment 1
The embodiment of the present invention verifies by infiltrating accelerated corrosion tests at the laggard line period of weathering steel surface-coated rusty scale stablizer, specifically comprises the steps:
Step 1: sample weathering steel being processed into 40mm × 60mm × 4mm, acetone oil removing, alcohol washes, dries up for subsequent use.
Step 2: preparation 100g rusty scale stabiliser solution, 45g water soluble acrylic resin+0.5g chromium sulphate+2gFe 2o 3+ 1gFe 3o 4+ 0.05g polyoxyethylene glycol+0.25g defoamer+0.25g wetting agent.With hairbrush, rusty scale stablizer is brushed at weathering steel specimen surface, dry 20min.
Step 3: (test medium is the NaHSO of 0.01mol/L to carry out 72h week leaching corrosion experiment to coating rusty scale stablizer sample and naked steel curved beam 3solution, experimental temperature 45 ± 2 DEG C, humidity 70 ± 5%, each loop cycle is 60min, wherein infiltrating time 12min, time of drying 48min.), weight-loss corrosion speed and rusty scale electrochemical analysis are carried out to the sample after experiment.
Fig. 1 is coating rusty scale stablizer and naked steel curved beam weight-loss corrosion speed, and after visible coating, sample weight-loss corrosion speed is starkly lower than naked steel.Fig. 2 and Fig. 3 is rusty scale electrochemical profiles after corrosion, and can see, after coating, sample chemical property is better than naked steel curved beam.This illustrates that rusty scale stablizer has very strong protective capability for weathering steel surface within the corrosion short period at initial stage, and it is obvious that rusty scale effect is stablized in generation.
