Background technology
One of effect of flocculation agent the particle aggregation suspended in solution is formed thick flock, to separate from solution.Thus be widely used in water treatment.
Existing flocculation agent can not play the effect of flocculation when processing haline water (NaCl mass percent are 100000-200000ppm) such as oilfield sewages, easy inefficacy, the salt resistance of polymer class flocculation agent urgently to be resolved hurrily, secondly, most polymer class flocculation agent severe reaction conditions, configures loaded down with trivial details at present.
Summary of the invention
The object of the present invention is to provide a kind of flocculation agent of water treatment.
Another object of the present invention is to provide a kind of method preparing above-mentioned flocculation agent.
For achieving the above object, flocculation agent provided by the invention, is formed through radical polymerization in aqueous phase by acrylamide, vinylformic acid, sodium carbonate, maleic acid list hexadecyl ester sodium salt;
In the total mass of water, acrylamide, vinylformic acid, sodium carbonate, maleic acid list hexadecyl ester sodium salt and initiator for 100:
Acrylamide 10 ~ 20%;
Sodium carbonate 10 ~ 15%;
Vinylformic acid 7 ~ 8%;
Maleic acid list hexadecyl ester sodium salt 1 ~ 3%;

Surplus is water.
In preferred flocculation agent, in the total mass of water, acrylamide, vinylformic acid, sodium carbonate, maleic acid list hexadecyl ester sodium salt and initiator for 100:
Acrylamide 16%;
Sodium carbonate 11%;
Vinylformic acid 7.3%;
Maleic acid list hexadecyl ester sodium salt 1.4%;
Initiator 0.08%, initiator to be made up of in mass ratio sodium bisulfite and Potassium Persulphate at 1: 1;
Surplus is water.
In described flocculation agent, the ratio of initiator sulfite hydrogen sodium and Potassium Persulphate is 1: 1.
The method of the above-mentioned flocculation agent of preparation provided by the invention:
The first step: add vinylformic acid after being dissolved in water in sodium carbonate and react;
Second step: add the single hexadecyl ester sodium salt dissolving of maleic acid in the first step reactant after, add acrylamide, be warming up to 30-35 DEG C after stirred under nitrogen atmosphere is even, add after initiator carries out initiation reaction and be warming up to 50-60 DEG C, and insulation reaction;
3rd step: after reaction terminates, namely obtain flocculation agent after granulation, drying, pulverizing.
In described method, after stirred under nitrogen atmosphere is even, be warming up to 31 DEG C; About 55 DEG C are warming up to after adding initiator for reaction.
In described method, initiator to be made up of in mass ratio sodium bisulfite and Potassium Persulphate at 1: 1.
The present invention improves the salt resistance of product by introducing anti-salt groups, and and the present invention only need react in single aqueous phase and prepare.
Embodiment
Flocculation agent of the present invention is the polymkeric substance that three kinds of monomers are polymerized jointly with maleic acid list hexadecyl ester sodium salt, sodium acrylate, acrylamide.Wherein, maleic acid list hexadecyl ester sodium salt is the main hydrophobic chain introduced in polymer architecture, for the water-soluble rear raising viscosity of polymkeric substance has important effect; Acrylamide, as principal monomer, for polymkeric substance provides main skeleton, makes polymkeric substance more condense; Sodium acrylate is as the mechanism unit improving further polymeric water-soluble, and the present invention is the polymkeric substance that synthetic molecular weight is as far as possible large under the condition as far as possible improving sodium acrylate monomers amount viscosity is high.
Concrete technical scheme of the present invention is:
In water, acrylamide, vinylformic acid, sodium carbonate, maleic acid list hexadecyl ester sodium salt, initiator total mass for 100:
Acrylamide 10 ~ 20%, sodium carbonate 10 ~ 15%, vinylformic acid 7 ~ 8%, maleic acid list hexadecyl ester sodium salt 1 ~ 3%, (sodium bisulfite: Potassium Persulphate mass ratio=1: 1), surplus is water to initiator 0.01 ~ 0.1%.
The preferred embodiment of the present invention:
Acrylamide 16%, sodium carbonate 11%, vinylformic acid 7.3%, maleic acid list hexadecyl ester sodium salt 1.4%, (sodium bisulfite: mass ratio=1 of Potassium Persulphate: 1), surplus is water to initiator 0.08%.
The preparation method of above-described embodiment:
The first step: neutralization is sent out and answered, and adds 11.9g sodium carbonate, adds vinylformic acid 8.05g after adding 70g water dissolution, react 20 minutes in three-necked flask.
Second step: polyreaction.Continue again in the first step reactant, add the single hexadecyl ester sodium salt 1.5g of maleic acid; dissolve 5 minutes; add acrylamide 18g again; 31 DEG C are risen to after stirred under nitrogen atmosphere is even; add 1: 1 sodium bisulfite and Potassium Persulphate initiator 0.09g causes; after initiation, temperature is slowly risen to about 55 degree, the lower reaction 4-5 hour of insulation.
