Abstract
The invention discloses a novel synthetic process for a hydrophobic polymeric flocculant. The synthetic process comprises the following steps: sequentially dissolving methyl methacrylate, acrylamide, acrylic acid, dimethyldiallylammonium chloride, sodium hydroxide and urea in pure water, wherein the usage amount of urea is 6%; adding sodium sulfite, a foaming agent and ammonium persulfate; neutralizing acrylic acid, and carrying out uniform mixing under stirring; taking out the polymer after allowing the mixture to stand, and performing purification; subjecting the polymer to drying and performing grinding so as to obtain the hydrophobic polymeric flocculant. The synthetic process provided by the invention can successfully synthesize the hydrophobic polymeric flocculant, and has the advantages of simple process, low required raw material and labor costs, and short synthesizing time; meanwhile, the synthesized hydrophobic polymeric flocculant has excellent instant solubility and storage stability, and is free of phenomenons of thinning due to long-time preservation, microgel formation, phase separation appearing and white precipitate generation; and through the addition of urea and controlling of the usage amount of urea in the process of synthesis, flocculation effect of the synthesized hydrophobic polymeric flocculant is improved.
Description
Technical field
The invention belongs to technical field of chemical synthesis, it is specifically related to the novel synthesis technique of a kind of hydrophobic polymeric flocculant.
Background technology
Organic floculant is according to the charge property of the charged group of polymerization single polymerization monomer, anion-polyacrylamide, cationic-type polyacrylamide, non-ionic polyacrylamide, amphoteric polyacrylamide etc. can be divided into several, can be divided into again synthetic and the big class of natural macromolecule flocculating agent two by its source, the present invention studies emphatically the hydrophobic interaction of flocculation agent. In the synthesis process method of current hydrophobic flocculation agent, technical process is not easy to implement, and the hydrophobic flocculation agent finished product purity of generation is low, hydrophobicity is poor, and reactant per pass conversion is low, and production process is complicated, production efficiency is low and cost height, is not suitable for scale operation.
Summary of the invention
In order to overcome the above-mentioned technical problem that prior art exists, it is an object of the invention to, the novel synthesis technique of a kind of hydrophobic polymeric flocculant is provided, the present invention not only production process simple, increase work efficiency, and the flocculant product purity generated is big and superior performance, is applicable to suitability for industrialized production.
The novel synthesis technique of hydrophobic polymeric flocculant provided by the invention, comprises the following steps:
(1) methyl methacrylate is dissolved in pure water;
(2) in the pure water again acrylamide, vinylformic acid, dimethyl diallyl ammonium chloride, sodium hydroxide, urea being dissolved in successively;
(3) then add S-WAT, stir evenly;
(4) add whipping agent and ammonium persulphate more successively, and add alkali and vinylformic acid is neutralized, stir evenly;
(5) standing and reacting 5-11h, takes out the polymer of reaction generation and purifies;
(6) polymer reaction generated is dry and grinds to form granular product, obtains hydrophobic polymeric flocculant.
The novel synthesis technique of hydrophobic polymeric flocculant provided by the invention, its useful effect is, overcoming prior art, to prepare operation in hydrophobic flocculation agent technological process more, the problem that workload is big, it is to increase working efficiency; Improve the per pass conversion of reactant and the product rate of resultant.
Embodiment
Below in conjunction with an embodiment, the novel synthesis technique of hydrophobic polymeric flocculant provided by the invention is described in detail.
Embodiment
The novel synthesis technique of the hydrophobic polymeric flocculant of the present embodiment, comprises the following steps:
(1) methyl methacrylate is dissolved in pure water;
(2) in the pure water again acrylamide, vinylformic acid, dimethyl diallyl ammonium chloride, sodium hydroxide, urea being dissolved in successively;
(3) then add S-WAT, stir evenly;
(4) add whipping agent and ammonium persulphate more successively, and add alkali and vinylformic acid is neutralized, stir evenly;
(5) standing and reacting 11h, takes out the polymer of reaction generation and purifies;
(6) polymer reaction generated is dry and grinds to form granular product, obtains hydrophobic polymeric flocculant.
The novel synthesis technique of hydrophobic polymeric flocculant, it is not necessary to loaded down with trivial details post-reaction treatment, operation simple possible, reduces technique cost greatly, and environmentally friendly pollution-free, and technical process is easy to implement, it is achieved that the suitability for industrialized production of product.
