| titleOfInvention | A kind of preparation method of the anti-dispersing flocculants of oil-well cement |
| abstract | The invention discloses a kind of oil-well cement preparation methods of anti-dispersing flocculants, using the method for free radical polymerization, it takes water as a solvent, using azo-bis-isobutyrate hydrochloride and ammonium persulfate as initiator, using disodium ethylene diamine tetraacetate as metal ion network mixture, with acrylamide, 2- acrylamide-2-methylpro panesulfonic acid, vinyltrimethoxysilane, sodium vinyl sulfonate, N, N- dimethylacrylamide, acrylyl oxy-ethyl-trimethyl salmiac, dimethyl diallyl ammonium chloride and n-vinyl pyrrolidone are that monomer copolyreaction under preset temperature range obtains anti-dispersing flocculants, so that anti-dispersing flocculants have preferable flocculation, cement slurry can be made not isolate in 80 DEG C of water not disperse, with good drop dehydration effect, the anti-dispersing flocculants of synthesis not breakdown strength in mortar architecture , not slow setting, use is safe, is readily produced. |
