Abstract
The invention relates to a flocculant which is prepared by performing free-radical polymerization on acrylamide, acrylic acid and sodium carbonate maleic acid monohexadecyl ester sodium salt in a water phase. On the basis of 100% of the total mass of water, acrylamide, acrylic acid, sodium carbonate, maleic acid monohexadecyl ester sodium salt and initiator, the flocculant is prepared from 10-20% of acrylamide, 10-15% of sodium carbonate, 7-8% of acrylic acid, 1-3% of maleic acid monohexadecyl ester sodium salt, 0.01-0.1% of initiator and the balance of water. The initiator is composed of sodium bisulfite and potassium persulfate in a mass ratio of 1:1. The invention also discloses a preparation method of the flocculant. The invention has obvious flocculation effect and is easy to prepare.
Description
Technical field
The present invention relates to a kind of flocculation agent, relate more specifically to the flocculation agent that a kind of water treatment is used.
The invention still further relates to the method for the above-mentioned flocculation agent of preparation.
Background technology
One of effect of flocculation agent is that the particulate polymerization that will suspend in the solution forms thick flock, so that separate from solution.Thereby aspect water treatment, be widely used.
Existing flocculation agent can not play the effect of flocculation when haline waters (the NaCl mass percent is 100000-200000ppm) such as processing oilfield sewage, lost efficacy easily, the salt resistance of the polymer class that needs to be resolved hurrily flocculation agent, secondly, at present most polymer class flocculation agent severe reaction conditions disposes loaded down with trivial details.
Summary of the invention
The flocculation agent that the object of the present invention is to provide a kind of water treatment to use.
Another purpose of the present invention is to provide a kind of method for preparing above-mentioned flocculation agent.
For achieving the above object, flocculation agent provided by the invention is formed through radical polymerization at aqueous phase by acrylamide, vinylformic acid, yellow soda ash, maleic acid list hexadecyl ester sodium salt;
Total mass in water, acrylamide, vinylformic acid, yellow soda ash, maleic acid list hexadecyl ester sodium salt and initiator is 100:
Acrylamide 10～20%;

Maleic acid list hexadecyl ester sodium salt 1～3%;
Initiator 0.01～0.1%, initiator is made up of sodium bisulfite and Potassium Persulphate;
Surplus is a water.
In the preferred flocculation agent, be 100 in the total mass of water, acrylamide, vinylformic acid, yellow soda ash, maleic acid list hexadecyl ester sodium salt and initiator:
Acrylamide 16%;
Yellow soda ash 11%;
Vinylformic acid 7.3%;
Maleic acid list hexadecyl ester sodium salt 1.4%;
Initiator 0.08%, initiator is made up of by mass ratio sodium bisulfite and Potassium Persulphate at 1: 1;
Surplus is a water.
In the described flocculation agent, the ratio of sodium bisulfite and Potassium Persulphate is 1: 1 in the initiator.
The method of the above-mentioned flocculation agent of preparation provided by the invention:
The first step: the back that is dissolved in water in the yellow soda ash adds vinylformic acid and reacts;
Second step: after in the first step reactant, adding the single hexadecyl ester sodium salt dissolving of maleic acid, add acrylamide, be warming up to 30-35 ℃ after stirring under the nitrogen protection, add initiator and carry out being warming up to 50-60 ℃ after the initiation reaction, and insulation reaction;
The 3rd step: reaction promptly gets flocculation agent after finishing after granulation, drying, pulverizing.
In the described method, be warming up to 31 ℃ after stirring under the nitrogen protection; Be warming up to about 55 ℃ after adding initiator for reaction.
In the described method, initiator is made up of by mass ratio sodium bisulfite and Potassium Persulphate at 1: 1.
The present invention is by introducing the salt resistance that anti-salt group improves product, and and the present invention only needs get final product in single aqueous phase prepared in reaction.
Embodiment
Flocculation agent of the present invention is to be three kinds of polymkeric substance that monomer is 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 of introducing in the polymer architecture, and improving viscosity for the water-soluble back of polymkeric substance has important effect; Acrylamide for polymkeric substance provides main skeleton, makes polymkeric substance condense more as principal monomer; Sodium acrylate is as further improving the water miscible mechanism unit of polymkeric substance, and the present invention is the synthetic molecular weight high polymkeric substance of big viscosity of trying one's best under the condition that as far as possible improves the sodium acrylate monomers amount.
