| titleOfInvention | A kind of compound salt tolerant hydrophobic association amphoteric flocculating agent and preparation method thereof |
| abstract | The present invention relates to a kind of compound salt tolerant hydrophobic association amphoteric flocculating agent and preparation method thereof.Adopt free radical polymerisation process, with the aqueous solution of aluminum chloride for polymerisation medium, with acrylamide, vinylformic acid and cation hydrophobic monomer for raw material, system pH is about 2 ~ 5, at 30 ~ 60 DEG C of polymerization 6 ~ 24h, namely obtain described compound salt tolerant hydrophobic association amphoteric flocculating agent and preparation method thereof.Compound hydrophobic association polyamphoteric electrolyte flocculation agent prepared by present method has excellent anti-salt property, a difficult problem for classic water-soluble polymkeric substance performance index degradation in high saline media, high salinity waste water can be solved, and there is fast, the inexpensive advantage of inorganic coagulant speed of response simultaneously. |
