The efficient compound corrosion inhibitor is prepared by triethanolamine, ethanolamine, sebacic acid, octanoic acid, boric acid, benzotrizaole and the like under certain temperature and normal pressure. Compared with existing products, the efficient compound corrosion inhibitor has the advantages that the inhibitor is efficient and evident in corrosion inhibiting performance, has a corrosion inhibiting effect on various metal, is good in stability in the hydraulic support hydraulic fluid and has long-term effectiveness.
Description
Technical field
The present invention relates to a kind of preparation method of the high efficiency composition inhibiter for hydraulic support hydraulic liquid, belong to coal mining equipment driving medium technical field.
Background technology
Hydraulic support, as comprehensive mechanical coal mining work major equipment, can provide safe working space for operator, and for adopting, fortune equipment provides effective propulsion source, is the key equipment that fully-mechanized mining working realizes safety, High-efficient Production.The support of hydraulic support, lifting, movement, passing and overload protection etc. are all realize by hydraulic support hydraulic liquid, and as " blood " of hydraulic bracket system, its product performance are particularly important.At present, domestic coal mine hydraulic supporting hydraulic liquid is usually aided with several functions additive by base oil and processes, and its oilness, stability, rust-preventing characteristic, non-corrosibility, all needs to meet with the consistency etc. of sealing material, and underground coal mine of being allowed for access uses.The performance of hydraulic support hydraulic liquid is good and bad, depends on the performance of functional additive to a great extent.
In actual use, hydraulic support hydraulic liquid, except meeting the corrosion inhibition to metals such as cast iron, steel, copper of regulation in MT76-2011 " hydraulic support oil in water emulsion, concentrated solution and High water cut hydraulic liquid thereof ", also needs other metal carrying such as zinc coating, aluminium alloy for corrosion inhibition.Existing inhibiter on market, effect is not remarkable, and can only play corrosion inhibition to limited several metal, also easily causes the instability of hydraulic support hydraulic fluid system.And high efficiency composition rust-preventive agent, physics and chemisorbed film can be formed in metallic surface, corrosives and metallic surface are kept apart, effectively can prevent the corrosion of hydraulic support, ensure hydraulic support safe and stable operation.
Summary of the invention
The object of the invention is to prepare a kind of efficient compound inhibiter for hydraulic support hydraulic liquid, all provide good inhibition protection to cast iron, steel, copper, zinc coating etc., be applied in hydraulic support hydraulic liquid, and permanently effective.
High efficiency composition inhibiter for hydraulic support hydraulic liquid of the present invention, it is characterized in that, with trolamine, Monoethanolamine MEA BASF, sebacic acid, sad, boric acid, benzotriazole for raw material, under certain temperature and normal pressure, reaction is obtained, main raw material and usage ratio following (wt%):
Trolamine 49 ~ 50%
Monoethanolamine MEA BASF 9 ~ 10%
Sebacic acid 9 ~ 10%
Sad 19 ~ 20%
Boric acid 9 ~ 10%
Benzotriazole 0.5 ~ 1%.
Production sequence of the present invention is: by trolamine, Monoethanolamine MEA BASF with sadly add reactor, be heated to 95 ~ 100 DEG C stir, add sebacic acid, boric acid, until white solid melts completely and has bubble to produce, be cooled to 60 DEG C, add benzotriazole to stir at least 60 minutes, stir evenly and leave standstill and obtain product afterwards.
Product is put in hydraulic support hydraulic liquid according to mass percentage 1 ~ 1.5% consumption, efficient corrosion mitigating effect can be obtained.
High efficiency composition inhibiter addition of the present invention is few, and the effect reached is excellent.Simultaneously to metals such as cast iron, steel, copper, there is corrosion inhibition, also to other metal such as zinc coating, aluminium alloy, also there is superior corrosion inhibition simultaneously.The present invention also has corrosion inhibition to various metals, and product is excellent in stability in hydraulic support hydraulic liquid, and permanently effective.
Embodiment
Below in conjunction with being that embodiment illustrates further to the present invention, but the present invention is not limited to following examples.
Embodiment 1
According to usage ratio, 50% trolamine and 10% Monoethanolamine MEA BASF, 20% are sadly added reactor jointly, be heated to 95 ~ 100 DEG C stir, add 9.5% sebacic acid, 9.5% boric acid, until white solid melts completely and has bubble to produce, be cooled to 60 DEG C, add 1% benzotriazole and stir 60 minutes, stir evenly and leave standstill and obtain product afterwards.Product is put in hydraulic support hydraulic liquid according to mass percentage 1.5% consumption and stirs evenly, good rust-preventing characteristic and non-corrosibility can be obtained, to zinc-plated test specimen, also there is obvious corrosion inhibition, be better than the hydraulic support hydraulic liquid oil adding common inhibiter.Test number is as follows:
| Project | Conventional hydraulic fluid test result | Hydraulic liquid test result after adding |
