Description
Technical field
The invention belongs to technical field of water treatment, and in particular to a kind of preparation side of modified polyacrylamide material for water treatment
Method.
Background technology
Since population increases and economic development, excessive exploitation and unreasonable development to resource and the influence money that generates
A series of problems of source quality, these problems have directly threatened the existence of we and descendants；Sewage disposal technology pair
The problems such as water-saving, energy saving, has a very important role, but is also caused to environment during the use of sewage treatment drug simultaneously
Certain influence.In cooling water system, water temperature is higher than under the various occasions of environment temperature, the fouling meeting of the inorganic salts such as calcium carbonate
Bring serious consequence.It is in recent years, growing using water technology that is alkaline, not adjusting pH value in water treatment field,
Corrosion-mitigation scale-inhibition medicament is wherein added, the application of low-phosphorous, without phosphorus formula is more and more extensive, and without phosphorus green water treatment agent has become
For the hot subject in terms of domestic and international water treatment agent research.Scientific utilization water treatment agent effectively anticorrosion and can prevent fouling,
Achieve the purpose that save water source and the energy to improve the utilization rate of equipment and water；
Currently, processing water resource pollution problem has a variety of methods such as physics, chemistry, biology, synthesis, but physical method is more
It is bad that there are treatment effects, handling rate instability problem；Biological method processing cost is excessively high, is not suitable for promoting the use of；It mostly uses
Chemical method carrys out treated sewage, but existing sewage-treating agent, agent formulations have secondary pollution, also can to environment
It has a certain impact.

It answers in kettle, the p-methyl benzenesulfonic acid of mixture weight 1-3% is added, be passed through nitrogen, it is 167-180 DEG C to adjust temperature of reaction kettle,
It is stirred to react 5-6 hours, obtains ester amine；
(3) hydroxypropyl methyl cellulose for taking 3-5 parts by weight is added in the dimethyl carbonate of 8-10 times of its weight, stirs
It mixes uniformly, obtains fiber solution；
(4) above-mentioned ester amine is taken, is added in fiber solution, is stirred evenly, is sent in reaction kettle, nitrogen is passed through, is adjusted
Temperature of reaction kettle is 50-60 DEG C, is reacted 30-40 hours, and the acrylamide of 100-130 parts by weight is added, and increases temperature of reaction kettle
Be 70-80 DEG C, be added above-mentioned initiator solution, insulated and stirred 3-5 hours, discharging, spray drying to get.
Advantages of the present invention：
The present invention is with stearic acid, triethanolamine blending reaction, by the carbonic acid of obtained ester amine and hydroxypropyl methyl cellulose
Dimethyl ester solution blending carries out quaternization reaction, with obtained quaternary ammonium salt treatment acrylamide monomer, gathers under initiator effect
It closes, to obtain the polyacrylamide of quaternary ammonium salt grafting, finished product stability of the invention is high, and water treatment efficiency is good, and safety collar
Guarantor property is good, and comprehensive performance is superior.
