A kind of environmental protection quick-dry type water-based antirust agent and preparation method thereof
Technical field
The invention belongs to water-based antirust agent technical fields, and in particular to a kind of environmental protection quick-dry type water-based antirust agent and its preparation
Method.
Background technique
Anti-corrosion of metal is to take various means, protects the metal for being easy corrosion, to reach its storage of extension or use
The purpose in service life.Metal erosion to human society bring direct losses be it is huge, many industrially developed country have carried out phase
Statistics is closed, the loss of metal erosion accounts for 1% to the 5% of national GNP as the result is shown;China was shown in data in 2014, was corroded
Caused by annual loss fail to keep an appointment as 2,000,000,000,000 RMB, the 3% of Zhan Dangnian GDP.Therefore metal erosion should attract great attention.
The measure of common anti-corrosion of metal currently on the market is antirust agent, antirust agent be then divided into antirust oil, antirust emulsion and
Water-based antirust agent etc..After application antirust oil or antirust emulsion, the surface of metal tools and instrument etc. can cover thickness thickness
Oil film, can not use immediately, need leading oil removing that could continue to operate, increase treatment process;And water-based antirust agent is then several
Metallic surface appearance and sense of touch are not influenced, in addition the considerations of the raising and economic interests of people's environmental consciousness, so being more prone to
And processing convenient water-based antirust agent friendly in use environment.Common environmentally-friendly water-borne antirusting agent has multiple using ethanol amine and acid
Match or is prepared by the substances such as polyol ester, there is certain rust-proof effect, but mostly short-term rust prevention (about 20 days) or higher cost;?
In use process, there is also volatile dry is not easy, it is unfavorable for subsequent processing and film forming is uniform.
Therefore, how to prepare one kind has medium-term and long-term antirust effect and lower-cost quick-dry type water-based antirust agent, and matches
Simple process processed, environmentally protective antirust agent are that this field has technical problem to be solved.

Shape, therefore it is suitable for the metal of various colors;It is very fast due to volatilizing, therefore be evenly distributed in metal surface, no sag phenomenon is not easy
In metal storage or transportational process because also it is unseasoned it is complete just scratched etc. caused by effective component situation unevenly distributed.
It joined suitable bleeding agent, film forming agent and thickener in the present invention, due to the effect of specific bleeding agent, the present invention
The good dispersion of water-based antirust agent, stability are long, mobility is good, therefore can preferably penetrate into the deep layer pore defect of metal surface
In, and drive the source of corrosion such as the air in micropore and microgroove, moisture away.Other products are compared, which is significantly improved from principle
Its rust-proof effect.On this basis, film forming agent and thickener are that water-based antirust agent has been still further provided in adhesive force, and film can
It is completely covered on each corner of metal surface, completely fine and close package is carried out, effective component can be made to maintain metal watch
The face longer time, to substantially extend antirust time.
Water-based antirust agent antirust time of the invention is long, it is recommended that using the resistance to neutrality of minimum concentration i.e. 5% dilution
Salt fog was up to 36 hours, can be antirust 18 months or more in practical application much higher than the antirust time of water-based antirust agent in the market.
Water-based antirust agent of the invention contains main corrosion inhibiter and auxiliary corrosion inhibiter, if individually with main corrosion inhibiter, resistance to neutral salt spray
Time is only 9~12 hours;If the resistance to neutral salt spray time is only 5~8 hours individually with auxiliary corrosion inhibiter;But two class corrosion inhibiter are matched
It closes and uses, not simple adduction of resistance to neutral salt spray time, but be unexpectedly obviously improved 60 hours, this is embodied
Has fabulous compatibility synergistic effect between major-minor corrosion inhibiter.
Water-based antirust agent of the invention is pH controllable type.Its pH value can be by the organic acids such as citric acid and sodium bicarbonate etc. no
The buffer of this kind of safe green of the strong base-weak acid salt of chloride ion-containing regulates and controls, and meets different rust-proof effects: this product exists
Between 8.6~8.8, the resistance to neutral salt spray time reaches 60 hours pH value when undiluted;If adjusting pH value between 8.1~8.6,
The resistance to neutral salt spray time is then at 48~60 hours;If adjusting pH value between 7.5~8.1, the resistance to neutral salt spray time 36~
48 hours;If adjusting pH value between 7.0~7.5, the resistance to neutral salt spray time was at 26~36 hours;If adjusting pH value 6.5
Between~7.0, the resistance to neutral salt spray time is then at 16~26 hours.To sum up, the present invention can be expired by controlling the height of pH value
The different antirust requirement of foot, being diluted with water for the prior art excessive will cause (more than 20 times) that film is too thin and rust-proof effect is unstable
Fixed situation, the present invention can be solved directly by adjusting pH value, meet the customization demand of user.
Water-based antirust agent of the invention is different from other manner of formulation during the preparation process and is to need several times quantitatively
Solvent is added, proves that the method for the present invention can make water-based antirust agent disperse more stable, appearance and be more fully apparent from through a large number of experiments, it is long-term to protect
Deposit no Precipitation.Raw materials used green safe, nontoxic, preparation process is easy to operate, and SOLUTION PROPERTIES is stablized.
