The surfactant is formed by compounding a non-ionic surfactant A and an ionic surfactant B; the nonionic surfactant A is one or a mixture of two of isooctanol polyoxyethylene ether (isooctanol polyoxyethylene ether produced by Jinan Xin chemical Co., Ltd.) and isodecyl alcohol polyoxyethylene ether (isodecyl alcohol ether produced by Jiangsu province Heian petrochemical plant) in any proportion.
The ionic surfactant B is 3-hexadecyl selenium-1-propyl sulfobetaine (self-made, with a chemical formula of CH)3(CH2)16SeSe(CH2)16CH3) Or dodecyl dimethyl betaine (chemical formula C)16H33NO2)。
Preferably, the ionic surfactant B is 3-hexadecyl selenium-1-propyl sulfobetaine.
The 3-hexadecyl selenium-1-propyl sulfobetaine is prepared from the following raw materials in parts by weight: 1-bromohexadecane (chemical formula is C)16H33Br)10-15 parts, selenium (chemical formula is Se)10-15 parts, sodium hydroxide (chemical formula is NaOH)20-25 parts, hydrazine hydrate (chemical formula is N)2H4·H2O)30-35 parts, N-dimethyl formamide (chemical formula is C)3H7NO)40-50 parts, sodium borohydride (NaBH)4)5-10 parts of 3-bromo-1-propanol (chemical formula is C)3H75-10 parts of BrO) and dimethylamine (C)2H7N)10-15 parts and 1, 3-propane sultone (C)3H6O3S)10-15 parts.
The preparation method of the ionic surfactant B (namely 3-hexadecyl selenium-1-propyl sulfobetaine) comprises the following steps:
(1) adding the N, N-dimethylformamide in parts by weight into a reaction kettle, starting stirring, heating to 85-90 ℃ while stirring, wherein the stirring speed is 250r/min, continuously adding the selenium, 1-bromohexadecane, sodium hydroxide and hydrazine hydrate in parts by weight into the reaction kettle when the temperature reaches 85-90 ℃, reacting for 3-4 hours to obtain a mixed solution A, wherein the selenium and the sodium hydroxide form NaSeNa under the action of the hydrazine hydrate, and then the 1-bromohexadecane is added to form CH3(CH2)16SeSe(CH2)16CH3。
(2) And cooling the reacted mixed solution A to room temperature, adding the sodium borohydride in the weight part, and continuing to react for 15-20min to obtain mixed solution B (sodium borohydride is used for breaking the diselenide ether bond to form selenium anions, so as to provide conditions for nucleophilic substitution in the next step).
(3) And continuously adding the 3-bromo-1-propanol, the dimethylamine and the 1, 3-propane sultone in parts by weight into the mixed solution B to continuously react for 20-30min to obtain mixed solution C.

It should be noted that the 3-hexadecyl selenium-1-propyl sulfobetaine prepared by the above method for preparing the ionic surfactant B is applied to all corresponding examples, namely the ionic surfactant B (specifically 3-hexadecyl selenium-1-propyl sulfobetaine) used in the corresponding examples is the same.
After the non-ionic surfactant A and the ionic surfactant B are compounded, mixed micelles can be formed in a solution, the critical micelle concentration of the surfactants is greatly reduced, and the cleanliness of products is greatly improved. Among them, the prior art and those skilled in the art generally only think of using span or tween as the main surfactant to prepare the cleaning agent, so the bottleneck problem of poor cleaning performance of the ink cleaning agent is difficult to break through, and even some researchers can select fatty alcohol polyoxyethylene ether surfactants, the researchers also think of using isooctanol polyoxyethylene ether and isomeric decyl alcohol polyoxyethylene ether. The 3-hexadecyl selenium-1-propyl sulfobetaine and the nonionic surfactant A form a compound system, so that the Krafft temperature is effectively reduced, the compounded surfactant has excellent surface interfacial tension and foaming performance, and the preparation method has obvious progress compared with the prior art.
It should be noted that the nonionic surfactant a and the ionic surfactant B in the present invention are only the name of a few specific surfactants in the art (i.e. the surfactants used in the present invention), and do not refer to the nonionic surfactant and the ionic surfactant which are conventionally selected, and the isooctanol polyoxyethylene ether and the isodecanol polyoxyethylene ether in the present invention are not used in the production of cleaning agents in the art, and are not available, and cannot be easily replaced or thought by those skilled in the art.
Because the cleaning agent has stronger cleaning force and stronger stripping property, if a corrosion inhibitor with weaker protective property such as benzotriazole is simply used, the corrosion inhibitor is not enough, a strong corrosion inhibitor matched with the cleaning agent needs to be added, otherwise equipment is seriously corroded, and the corrosion inhibitor is composed of hexadecylamine (the molecular formula is C)16H35N), 2-ethylbutenal (molecular formula is C)6H10O) and organic strong acid, wherein the mass ratio of the hexadecylamine to the 2-ethylbutenal to the organic strong acid is 3: 1: 1 (the corrosion inhibition effect is best at this moment), the strong organic acid is benzenesulfonic acid (the molecular formula is C)6H8O4S), under the general conditions, hexadecylamine is difficult to react with 2-ethylcrotonaldehyde, so a specific organic acid is selected as a catalyst to catalyze the reaction. The research of a team finds that under the condition of organic weak acid (such as benzoic acid, acetic acid and the like), aldehyde group in 2-ethyl crotonaldehyde is difficult to open, and the catalytic effect is poor, so that the invention selects benzenesulfonic acid with stronger acidity as a catalyst, successfully prepares an expected corrosion inhibitor, adds the corrosion inhibitor into the cleaning agent, can effectively prevent the cleaning agent from corroding equipment when the equipment is cleaned, and has the action mechanism that: the corrosion inhibitor can form a layer of barrier film on the surface of metal in the cleaning process, so that the metal is prevented from directly contacting with corrosive substances.
The preparation method of the corrosion inhibitor comprises the following steps: adding hexadecylamine and 2-ethylbutenal in the mass ratio into a reaction kettle, starting stirring at the stirring speed of 300-350r/min, heating to 45-50 ℃ while stirring, adding benzenesulfonic acid in the mass ratio when the temperature is raised to 45-50 ℃, and continuing to react for 20-30min to obtain the corrosion inhibitor (Schiff base reaction)Because the active ingredients are not uniformly distributed, the protection effect is not ideal and the active ingredients are easy to stand and layer, the invention adds the regulator for dispersing the corrosion inhibitor, is convenient for long-term storage and improves the protection effect, and the regulator is isopropanol (the molecular formula is C)3H8O)。
The alkaline auxiliary agent is sodium carbonate (chemical formula is Na)2CO3) (ii) a The anti-redeposition agent is triethanolamine (chemical formula is C)6H15NO3) And acrylic acid-maleic anhydride copolymer (chemical formula C)7H6O5) One or a mixture of two of the above in any proportion; the penetrating agent is dioctyl sodium sulfosuccinate (dioctyl sodium sulfosuccinate produced by Xingliu environmental science and technology, Inc.).
The solubilizer is 3-methoxy-3-methyl-1-butanol, and the molecules of the 3-methoxy-3-methyl-1-butanol simultaneously have hydroxyl and methoxy, so that the solubilizer forms strong hydrogen bonds in and among molecules and has outstanding dissolving capacity.
A method for preparing the cleaning agent, which comprises the following steps:
(1) and main solvent pretreatment: preheating the reaction kettle to 50-55 ℃, adding the environment-friendly solvent in parts by weight into the reaction kettle, starting stirring, adding the nonionic surfactant A and the ionic surfactant B in parts by weight while stirring, and continuously stirring for 10-20min at the stirring speed of 200-300r/min to obtain a uniform and transparent solution. The purpose of adding the surfactant is to ensure that the surfactant can be stably distributed in the system firstly, so that the activity is prevented from being reduced and the effect is prevented from being poor.
(2) And mixed discharging: and (2) adding the alkaline assistant, the corrosion inhibitor, the penetrating agent, the 3-methoxy-3-methyl-1-butanol, the anti-redeposition agent, the regulator and the deionized water in parts by weight into the transparent solution obtained in the step (1), and continuously stirring for 15-20min at the stirring speed of 200-300r/min to obtain the water-based UV ink cleaning agent.
