| titleOfInvention | A kind of polymer microballoon and preparation method thereof that Bulking Time is controllable |
| abstract | The invention discloses a kind of polymer microballoons that Bulking Time is controllable, are polymerize by the following raw material component cross-link and are made: acrylamide monomer, water-solubility function monomer, crosslinking agent A, crosslinking agent B, emulsifier, initiator, decentralized medium and deionized water；Crosslinking agent A is N,N methylene bis acrylamide；Crosslinking agent B is polyethyleneglycol diacrylate.Acrylamide: S1, being dissolved in deionized water by the preparation method of polymer microballoon, function monomer, crosslinking agent A, crosslinking agent B is added, stirring is to being completely dissolved；S2, emulsifier is added into decentralized medium, stirs, solution made from step S1 is added, stir 2~5h, obtain reversed-phase polymerization reaction solution system；S3, initiator is added in reversed-phase polymerization reaction solution system, stirring, under oxygen-free environment, temperature is increased to 35~50 DEG C, reacts 3~5h, obtains polymer microballoon.Polymer microballoon of the invention can control speed of expansion and the time of polymer microballoon by adjusting the ratio of two kinds of crosslinking agents. |
