Description
Technical Field
The invention relates to a corrosion inhibitor, in particular to a preparation method and application of a pickling corrosion inhibitor.
Background
The metal material plays a very important role in modern industrial and agricultural, mechanical, transportation, national defense, scientific and technical departments and the like. However, metallic materials are extremely corrosive, and the amount of metal scrapped annually worldwide is statistically equivalent to 1/4-1/3 annual output; the annual losses due to corrosion account for 3.1% -4.5% of the total value of national economic production (GDP). The corrosion inhibitor has become one of the most effective corrosion prevention technologies due to the advantages of convenient use, wide application range, low investment, quick response and the like.
Acid in chemical production is widely applied to the operations of acid washing, acid leaching, acid dipping, oil well acidification and the like. Commonly used acids are mineral acids such as hydrochloric acid, sulfuric acid and phosphoric acid. In practice, corrosion inhibitors are added to inhibit corrosion of metal components in acid solutions during the various acid treatment processes. Satisfactory inorganic salt corrosion inhibitors were developed before the 80's of the 20 th century: chromate, nitrite, mercury salts, arsenides, but these inorganic salts are carcinogenic and polluting the environment, so that their use is limited. After the 80 s in the 20 th century, people mainly focus on the research of organic corrosion inhibitors, and triazole derivatives, phenothiazine and derivatives, quinoline and derivatives thereof, pyrrole derivatives, pyrazole derivatives, thiazole derivatives and organophosphorus corrosion inhibitors with ideal corrosion inhibition effects are provided. However, the cost of the organic corrosion inhibitor is high, the water solubility is poor, and particularly, the water eutrophication is caused by the discharge of the organic phosphorus corrosion inhibitor, so that the development and the application of the corrosion inhibitor are seriously hindered. With the enhancement of environmental protection consciousness, the research and development of the environment-friendly corrosion inhibitor with low cost are widely concerned at home and abroad. In recent years, the plant corrosion inhibitor extracted and prepared from plants has the characteristics of wide source, low cost, environmental friendliness and the like; especially, the plant corrosion inhibitor extracted and prepared from the alien invasive plants has environmental benefits and economic benefits, and can change waste into valuable. In conclusion, the research and development of the plant compound corrosion inhibitor with low cost are the common concern all over the world.
Jatropha curcas is an internationally recognized tree species for producing biodiesel and is widely cultivated around the world. The barbadosnut seed cake is a byproduct of barbadosnut seeds after barbadosnut oil extraction, the yield is huge, but the barbadosnut seed cake has toxicity, so the barbadosnut seed cake is discarded or used as a fertilizer after general production and is not comprehensively utilized, so the cost of the produced product is too high, and the development is restricted. The barbadosnut cake contains abundant protein (the content of crude protein is up to more than 30 percent), and various amino acids can be obtained by extraction, so that the corrosion inhibitor prepared by the method is used for corrosion protection of metals. The subject group makes a great deal of research on the corrosion inhibition effect of the barbadosnut cake extracting solution on carbon steel and aluminum, and 1-5% of hydrochloric acid is used in the conditions that the liquid-solid ratio is 8:1 (g/mL), the extraction temperature is 60-80 ℃, the extraction time is 2-4 h, the barbadosnut cake extracting solution is obtained, the corrosion inhibition effect on aluminum is good, the corrosion inhibition effect on carbon steel is good, and no research is carried out on the corrosion inhibition aspect of zinc, zinc-aluminum alloy or hot-dip galvanized and zinc-aluminum alloy coating steel. The barbadosnut cake contains anti-nutritional factors and toxins such as phorbol ester, phytohemagglutinin, trypsin inhibitor and the like, so the application field is limited to a certain extent, and no report about the composition or synergism of the barbadosnut extracted pickling corrosion inhibitor and other plant extracts exists at present, and further research and development are needed.

In order to achieve the purpose, the following technical scheme is adopted:
the pickling corrosion inhibitor comprises the following components in parts by weight: 20-60 parts of barbadosnut cake extract, 10-30 parts of eucalyptus bark extract, 2-4 parts of propylene glycol, 3-5 parts of sodium laurate and 1-5 parts of nicotinic acid.
The preparation method of the pickling corrosion inhibitor comprises the following steps: adding 20-60 parts of barbadosnut cake extract, 10-30 parts of eucalyptus bark extract, 3-5 parts of sodium laurate and 1-5 parts of nicotinic acid into a reaction kettle, mixing and stirring, heating to 60 ℃, reacting until all materials are completely dissolved, adding 2-4 parts of propylene glycol, uniformly mixing, cooling and discharging.
The preparation method of the barbadosnut cake extract comprises the following steps:
(1) pulverizing the barbadosnut cake with a pulverizer to make the particle size of the barbadosnut cake be 80-100 meshes;
(2) adding 0.04-0.08% NaHCO into Jatropha curcas cake3Heat-treating the solution at the temperature of 120-130 ℃ for 20-30 minutes;
(3) extracting with 85% ethanol as extractant at 52-53 deg.C for 2-3 hr according to the ratio of ethanol solution to Jatropha curcas cake 1 (12-15);
(4) adding hydrochloric acid solution into the extracted barbadosnut cake according to the liquid-solid ratio of (6-9) to 1, and extracting at 60-100 deg.C under stirring for 5-8 hr;
(5) filtering or centrifuging the mixed solution of the acid solution and the barbadosnut cake, and collecting filtrate or supernatant.
The extraction method of the eucalyptus bark extract comprises the following steps: mixing the eucalyptus bark with 5-8% hydrochloric acid solution according to the weight ratio of (10-13): 1, extracting at 80-100 deg.C for 5-7 hr, filtering, and concentrating the filtrate at 80 deg.C.
The use method of the pickling inhibitor comprises the steps of taking dilute acid as a pickling solution, adding the pickling inhibitor accounting for 3-8% of the total mass of the dilute acid, controlling the temperature of the mixed solution at 40-50 ℃, then adding the material to be cleaned into the mixed solution, and immersing for 2-4 hours; the diluted acid solution is a mixed solution of 3% hydrochloric acid, 2-3% tartaric acid and 1-2% citric acid.
The barbadosnut cake extract contains a large amount of unpaired polar groups, and the groups can form a very firm complex protective film on the surface of metal, and the protective film can prevent the metal from being further oxidized. The amino acid has hydrophilic amino group, carboxyl group and hydrophobic-R group, has certain surface activity, can be adsorbed on the interface of metal and solution, increases the activation energy of interface reaction, and changes the double electric layer structure of the interface, so that the cathode or anode in the conjugation reaction is strongly retarded, and the corrosion rate of metal is sharply reduced. In addition, after polar groups of amino and carboxyl are adsorbed on the metal surface, one end of a non-polar group-R is directionally arranged on the metal surface to form a hydrophobic film, so that charges or substances related to corrosion reaction are prevented from transferring, and as a result, an acidic medium is extruded by corrosion inhibitor molecules to be separated from the metal surface, and the corrosion rate of the metal is reduced. The eucalyptus bark extract and the barbadosnut cake extract have a synergistic effect and an obvious effect.
Compared with the prior art, the invention has the following beneficial effects: the invention overcomes the problem that the barbadosnut cake extract has toxic components, and the barbadosnut cake extract and the eucalyptus bark extract have obvious synergistic effect, high corrosion inhibition efficiency and strong adaptability. The acid corrosion inhibitor provided by the invention is simple and effective in use method, safe, harmless and biodegradable, can be applied to cleaning of petrochemical equipment, boilers and even tap water pipelines, and has good development prospect.
