Calcium phosphate cement fluid loss agent |
| abstract |
The invention relates to a calcium phosphate cement fluid loss agent. The calcium phosphate cement fluid loss agent is a pentabasic copolymer. The pentabasic copolymer is prepared from comonomers such as 20-50 parts by weight of an unsaturated amide monomer, 30-50 parts by weight of 2-acryloylamino-2-methylpropanesulfonic acid, 1-10 parts by weight of unsaturated monocarboxylic acid, 0.05-0.5 parts by weight of methylene bisacrylamide and 1-20 parts by weight of allylpolyoxyethylene ether. The calcium phosphate cement fluid loss agent controls a calcium phosphate cement slurry water loss rate within 50ml/30min at a temperature of 50-150 DEG C. |
