Abstract
The invention discloses a kind of steel structure aqueous rust transformation liquid, including following component: composite organic acid, bleeding agent, nano-titanium dioxide and water.Such steel structure aqueous rust transformation liquid is mainly used for the steel structure surface that gets rusty, and the rusty scale of steel structure surface can be carried out to extraordinary turn of rust, after doing solid work to turn rust liquid, continues to apply priming.The steel structure aqueous rust transformation liquid is constituted using environmentally protective ingredient; without any poisonous and hazardous ingredient (such as VOC); when use; the conversion fluid is successively used with aqueous rust-proof coatings; steel construction can be protected to greatest extent, prevents it from getting rusty again, improve the service life of steel; it does not need to carry out the work that derusts on a large scale before construction, saves a large amount of financial resources and manpower.
Description
Technical field
The present invention relates to a kind of steel structure aqueous rust transformation liquid, belong to anticorrosive paint technology field.
Background technique
With the development of China's steel and iron industry, steel construction in construction projects using increasing.Steel construction has strong
Spend height, good toughness, the series of advantages such as easy to make, speed of application is fast, building cycle is short.But there is also apparent weak
Point --- it easily corrodes.According to statistics, the whole world every year due to metal erosion caused by economic loss be about 700,000,000,000 dollars.Coating
Coating antiseptic due to have have excellent performance, manufacture and some other materials such as easy for construction, cheap and method it is incomparable
The advantages of, thus usually become top-priority object when selecting anti-corrosion measure.
For the steel that got rusty, it is also a kind of good method that brushing anticorrosive paint, which carries out anti-corrosion,.But traditional side
Method, it is necessary to derusting operation is carried out to steel in advance, and this work occupies the 40% of entire anti-corrosion cost.
Summary of the invention
In order to more preferably solve the problems, such as the cost problem of derusting and protect steel construction to the greatest extent, the present invention provides one kind
Steel structure aqueous rust transformation liquid, the conversion fluid can be by rust transformations at stable black chelate, so as to avoid extensive
The cost problem of derusting.
A kind of steel structure aqueous rust transformation liquid, including following component: composite organic acid, bleeding agent, nano-titanium dioxide
And water；
The composite organic acid is tannic acid, catechol, pyrogallol, the mixing of salicylic acid and phytic acid.Mass ratio
Example be respectively tannic acid 25%-35%, catechol 15%-25%, pyrogallol 15%-25%, salicylic acid 5%-15% and
Phytic acid 5%-15%.
Composite organic acid, bleeding agent, nano-titanium dioxide and the water, mass ratio are as follows: composite organic acid 35%-
45%, bleeding agent 5%-15%, nano-titanium dioxide 5%-15% and water 35%-45%.
The nano-titanium dioxide is Nano grade nanometer anatase titania, diameter 10-100nm；
The bleeding agent is isopropanol；
The application method of above-mentioned rust transformation liquid is, first in the steel structure surface brushing aqueous rust conversion fluid that gets rusty, wait turn
After rust liquid is done solid work, continue to coat one layer of aqueous rust-proof coatings.
The thickness of the rusty scale of the steel structure surface that gets rusty is preferably controlled within 100um, if rusty scale it is blocked up or
There are floating rust, then should slightly be derusted.
The invention has the benefit that
1. rust transformation liquid of the invention is by using composite organic acid, relative to turn rust liquid for using a kind of organic acid
It says, it is compound due to organic acid, so that the entire acid reduction for turning rust liquid system, can be such that iron rust is formed more stable, finer and close
Inertia black chelate.
2. it is added to rust transformation liquid using isopropanol as bleeding agent, it, can not only relative to the system for not adding isopropanol
The osmosis for turning rust liquid is improved, and the surface drying for turning rust liquid can be dramatically speeded up and done solid work.
3. nano-titanium dioxide is added to rust transformation liquid, relative to nano-titanium dioxide is not added, due to nano-silica
Changing titanium has higher thermal stability, non-toxic, the properties such as non-migratory, turn rust liquid water resistance, and the properties such as salt fog resistance are more preferable.
When to match with water-based anticorrosive paint, the properties such as the salt fog resistance of system are more enhanced.
4. taking separated brushing technique of the invention that will turn rust liquid and mix with water paint to brush again than traditional
Technique, storage time can more long.
