Abstract
The present invention relates to a high concentration gasified antirust liquid preparation method for dilution to prevent erosion of iron and nonferrous metal; metal electrons and anticorrosive compound on the metal surface are used to form a colloidal insoluble protective film, thereby achieving the gasified antirust liquid preparation method of inhibiting rusty performance. Firstly purified water is put to a stirrer, then potassium metasilicate and additive-sodium metasilicate and sodium benzoate are put to the purified water and stirred under the condition of 40 DEG C till suspension fully becomes transparent, then is cooled to the room temperature to prepare a mixed material A; polyethylene glycol, propanediol and benzotriazole are put to another stirrer and uniformly stirred under the room-temperature condition to prepare a mixed material B; then the equal amount of the mixed material A solution is put to the mixed material B solution; triethanolamine is put and stirred in the room temperature to have reaction and form antirust liquid; the technique condition is simple and easy to control; the product has high yield and good quality and can replace the prior antirust liquid and produce positive effect.
Description
Technical field:
That the present invention relates to is a kind of preparation method who prevents the dilution of Ferrous ﹠ Non Ferrous Metal corrosive with high-concentration gasified rust-proofing liquor; be that a kind of metal electron of metallic surface and anti-corrosion compound of utilizing forms the insoluble protective membrane of colloid, the manufacture method of the gasified anti-rust liquid of performance thereby the realization inhibition is got rusty.
Background technology:
Along with industry and expanding economy, utilize various metals particularly the various products of ferrous metal production obtained widely using, simultaneously, the metal loss that produces because of various corrosion is also more and more.Particularly after doing liquid conveying or the manufacturing of pump series products after the welding such as underground pipeline, carry out the various occasions of weld, antirust product of present employed liquid type or usage quantity are too many, use the extent of corrosion of back product sharply to rise, there are a lot of side effects, and existing on the market rust protection liquid all contains the medicine to environment and human body harmful such as heavy metal such as chromium or nitrite, causes the serious environmental pollution problem easily.In addition, people are being devoted to research and develop the various technology that prevent that metal from getting rusty, some is quite ripe, particularly utilize the principles of chemistry to prevent that seabed or underground corrosion of metal technology from also having obtained significant results, but the high-concentration gasified rust-proofing liquor and the technology of preparing thereof that are used for various metals are still waiting further exploitation and development, have had not yet to see desired result.
Summary of the invention:
The objective of the invention is to overcome the existing in prior technology problem, produce the degradable formula high-concentration gasified rust-proofing liquor of not only economy but also environmental protection with the New Type Material pharmaceutical chemicals of environmental protection through rational scientific matching and modulation.
To achieve these goals, the present invention utilizes the non-publicly-owned electron pair of New Type Material to combine the principle that forms the soluble chelating thing with metal ion, is mixed with batch mixing A earlier, is mixed with mixed material B again, is mixed in proportion then and is prepared into product.In order to increase the rustless property of product to metal, add the New Type Material potassium silicate in the solution, and mix with Sodium Benzoate, phenylpropyl alcohol triazole, propylene glycol, trolamine, polyoxyethylene glycol, make the product of preparation have very strong metal rust preventing performance.
Realization of the present invention is put into pure water earlier in agitator, put into potassium silicate and additive Starso, Sodium Benzoate again, stirs 30-90 minute under 40 ℃ of conditions, and transparent fully up to suspension liquid, cool to room temperature makes batch mixing A then; After putting into polyoxyethylene glycol, propylene glycol, phenylpropyl alcohol triazole in another agitator, stir at ambient temperature again, make mixed material B; Put into equivalent batch mixing A solution then in mixed material B solution, put into trolamine again, stirred 30-50 minute with 30rpm/min speed under the normal temperature, reaction generates and concentrates gasified anti-rust liquid.
The present invention prepares the material composition weight percent of batch mixing A solution: be pure water 95.40%, potassium silicate 0.15%, Starso 0.05%, Sodium Benzoate 4.4%; The material composition weight percent of mixed material B solution is: polyoxyethylene glycol 14.26%, propylene glycol 85.57%, phenylpropyl alcohol triazole 0.17%; The mixed weight proportioning of batch mixing A and mixed material B is 1: 1.
The present invention is owing to added potassium silicate and additive Starso, and the economy product can be diluted so belong to its stable chemical performance at high proportion, and its product also can carry out gasified rust-proofing for a long time not containing under the physical environments such as chromium system or nitrite; Compared with prior art, processing condition are simple and easy to control, and product goes out the rate height, and quality is good, and product can replace existing rust protection liquid and produce positively effect.
Embodiment:
Method that the invention is further illustrated by the following examples and effect thereof.
Embodiment 1:
The preparation of present embodiment batch mixing A: in 300 liters agitator, put into the pure water of 65kg, put into potassium silicate 0.1kg again, additive Starso 0.03kg, Sodium Benzoate 3kg stirred 60 minutes under 40 ℃ of conditions, till suspension liquid is transparent fully, cool to room temperature makes batch mixing A then.
The preparation of present embodiment mixed material B: in 300 liters agitator, put into polyoxyethylene glycol 20kg, propylene glycol 120kg, phenylpropyl alcohol triazole 0.24kg stirs at ambient temperature, makes mixed material B.
Present embodiment mixes batch mixing A and mixed material B: put into equivalent batch mixing A solution in mixed material B solution, put into trolamine 2kg again, stirred 40 minutes with 30rpm/min speed under the normal temperature, reaction generates 210kg and concentrates gasified anti-rust liquid.It is as follows to carry out the applicability test with the rust protection liquid that makes:
Test conditions: 35 ℃, the test of aqueous solution thermostatic bath, test period: 30 days
Test piece: length is after the metal testing plate of 3cm is carefully smeared with aluminium cloth, to clean with Virahol again.
Test method: 1) in beaker by rust protection liquid: water=weight ratio was diluted to antirust solution in 1: 100;
2) test piece is put into 1) solution;
3) temperature of thermostatic bath is set at 35 ℃, and beaker is put into thermostatic bath, per hour observes the situation of getting rusty.Distinguish the different Dilution ratios of conversion again, test-results such as table 1.
Table 1: the get rusty situation of product of the present invention under different Dilution ratio conditions
