Abstract
The invention discloses a preparation method of an acid-alkali-resistant wetting agent.The preparation method particularly comprises the steps that 0-15 parts by mass of maleic anhydride, 0-15 parts by mass of dodecyl polyoxyethylene ether, 0-15 parts by mass of nonylphenol polyoxyethylene ether and 0-5 parts by mass of p-toluenesulfonic acid are added into a reaction kettle, the vacuum degree is controlled within the range of 0.095 MPa-0.1 MPa at the temperature of 120 DEG C-220 DEG C, reacting is performed for 2-10 h, an acid value and a hydroxyl value of reaction liquid are measured, and if the acid value and the hydroxyl value do not reach the standard, reacting is continuously performed until the acid value and the hydroxyl value both reach the standard; if the acid value and the hydroxyl value reach the standard, the temperature of the reaction liquid is lowered to 80 DEG C-90 DEG C, 0-8 parts of by mass of sodium hydrogen sulfite and 0-5 parts by mass of sodium acetate are added, stirring is performed for 4 h, and then the acid-alkali-resistant wetting agent is obtained.The wetting agent has the advantages of being good in wetting effect, capable of resisting the extreme conditions of strong acid and strong alkali and wide in application range.
Description
Technical field
The invention belongs to technical field of surfactant, relate to the preparation method of the wetting agent of a kind of acid and alkali-resistance.
Background technology
Wetting agent is all made up of hydrophilic group and lipophilic group, when contacting with the surface of moistening object, lipophilic group is attached to the surface of object, hydrophilic group is then outwards towards in liquid, liquid is made to form continuous phase at body surface, thus play the effect of moistening, wetting agent is mainly used in building, coating, paint, dyestuff, weaving, pesticide, leather and other field of polymer technology, but in actual application, owing to the Acidity of Aikalinity of institute's moistening body surface exists a great difference, make the range of wetting agent by great limitation.
Summary of the invention
It is an object of the invention to provide the preparation method of the wetting agent of a kind of acid and alkali-resistance, the method is simple to operate, and reaction condition is easily-controllable, and the humectant prepared to have wetting effect good, acid and alkali-resistance scope is wide, is resistant to strong acid, the extreme condition of highly basic.
For achieving the above object, the preparation method of the wetting agent of the acid and alkali-resistance that the present invention provides, particularly as follows: by 0～15 mass parts maleic anhydrides, 0～15 mass parts Dodecyl Polyoxyethylene Ethers, 0～15 mass parts NPEs and 0～5 mass parts p-methyl benzenesulfonic acid add in reactor, at 120～220 DEG C, control vacuum between-0.095 MPa～-0.1 MPa, reaction 2～10 h, the acid number of detection reactant liquor and hydroxyl value, if acid number and hydroxyl value all reach standard value, then reacting liquid temperature is down to 80～90 DEG C, add the sodium sulfite of 0～8 mass parts, the sodium acetate of 0～5 mass parts, stir 4 h, obtain the wetting agent of acid and alkali-resistance；
If acid number and hydroxyl value have a not up to standard value, then proceed reaction, after acid number and hydroxyl value all reach standard value, again reacting liquid temperature is down to 80～90 DEG C, add the sodium sulfite of 0～8 mass parts, the sodium acetate of 0～5 mass parts, stirs 4 h, obtains the wetting agent of acid and alkali-resistance；
