Problems solved by technology

Although traditional vapor phase corrosion inhibitors such as dicyclohexylamine nitrite, sodium nitrite + urea + monoethanolamine benzoate have certain corrosion inhibition effects, they have really produced highly efficient, low-toxic, and environmentally friendly corrosion inhibitors for silicon steel. Vapor-phase corrosion inhibitors are still difficult

Embodiment 1

[0017] Dissolve 10 parts of boric acid and 33 parts of 75% triethanolamine in 175 parts of deionized water successively, fully stir at a temperature of 25°C and a pressure of 0.1 MPa, and then add deionized water to 300 parts (ie plus 125 servings). Under the above reaction conditions, 10 parts of morpholine malate and 45 parts of hexamethylenetetramine were added successively to make them fully dissolved, and after the reaction was complete, 3 parts of PVA emulsion with a concentration of 48wt% were added to form a uniform The coating solution is coated on anti-rust base paper or non-woven fabric according to the above method to make environment-friendly gas-phase anti-rust paper for silicon steel and environment-friendly gas-phase anti-rust non-woven fabric for silicon steel.

Embodiment 2

[0019] 12 parts of boric acid and 38 parts of 75% triethanolamine were successively dissolved in 200 parts of deionized water, at a temperature of 15° C. and under a pressure of 0.09 MPa, fully stirred to make the reaction complete, and then added deionized water to 570 parts (ie Add 370 parts again), under the above-mentioned reaction conditions, 15 parts of morpholine malates, 55 parts of hexamethylenetetramines are added successively, make it fully stirred, and adding concentration is 7 parts of the PVA emulsion of 48wt% after reaction is complete, Make a uniform coating solution, and apply it on the anti-rust base paper or non-woven fabric with the outer layer compounded with moisture-proof and air-permeable plastic film according to the above method to make environmentally friendly reinforced vapor phase anti-rust paper for silicon steel and environment-friendly silicon steel. Reinforced vapor phase anti-rust non-woven fabric.

Embodiment 3

[0021] 11 parts of boric acid and 33.5 parts of 75% triethanolamine were successively dissolved in 188 parts of deionized water, at a temperature of 20° C., under a pressure of 0.11 MPa, fully stirred to make the reaction complete, and then enough deionized water to reach 435 parts ( That is to add 247 parts), under the above reaction conditions, 12.5 parts of morpholine malate and 50 parts of hexamethylenetetramine are added successively to make it fully dissolved, and after the reaction is complete, then add the concentration of 48wt% 5 parts of PVA emulsion, make it into a uniform coating solution, and apply it on the antirust base paper layer of composite carrier plastic / braid / resin / antirust base paper or composite carrier plastic / braid / resin / non-woven fabric according to the above method or On the non-woven fabric layer, it is made into environment-friendly silicon steel special boned vapor phase antirust paper and environment friendly silicon steel special boned gas phase...

Abstract

The invention discloses a kind of environment friendly silcon steel special-purpose gas phase corrosion inhibitor and uses this corrosion inhibitor production each kind of silcon steel special-purpose gas phase corrosion inhibitor packing material. The silcon steel special-purpose gas phase corrosion inhibitor is by the malic acid with the boric acid three ethanoic acid amines, the hexamethylene tetramine coordination is composed, regardless of is or the non- orientation silcon steel all has the unique gas phase slow eclipse effect to the orientation silcon steel. With this environment friendly gas phase corrosion inhibitor production silcon steel special-purpose gas phase anti-tarnish paper, the silcon steel special-purpose gas phase guard against the rust adhesive-bonded cloth, the silcon steel special-purpose enhancement gas phase anti-tarnish paper, the silcon steel special-purpose enhancement gas phase guards against the rust adhesive-bonded cloth, the silcon steel special-purpose Canada bone gas phase anti-tarnish paper, the silcon steel special-purpose Canada bone gas phase guards against the rust adhesive-bonded cloth suitable seals or the short-term for a long time to the orientation silcon steel with the non- orientation silicon steel plate and the strip and its the finished product temporarily guards against the rust. The environment friendly silcon steel special-purpose gas phase corrosion inhibitor packing material guards against the rust effect well, guards against the rust time long, the use convenient, safe is harmless.

Description

technical field [0001] The invention relates to an environment-friendly gas-phase corrosion inhibitor special for silicon steel and packaging materials for various gas-phase corrosion inhibitors special for silicon steel produced by using the corrosion inhibitor. Background technique [0002] In recent years, the international community has paid great attention to the protection of the environment and human health, strengthened environmental protection legislation, and put forward higher requirements for the development of corrosion inhibitors, especially requiring the promotion of green chemistry. The concept of environmentally friendly corrosion inhibitors is proposed on the basis of green chemistry. [0003] In March 2003, at the American Society of Corrosion Engineers (NACE) Corrosion / 2003 academic annual meeting and exhibition held in San Deigo, USA, it was clear that the development of new, efficient and low-toxic gas phase corrosion inhibitors is the key to the develo...
