| titleOfInvention | Anti-settling auxiliary agent and preparation method and application thereof |
| abstract | The invention discloses an anti-settling auxiliary agent, and a preparation method and application thereof. Generating a functional monomer B at a certain temperature by using sultones, the functional monomer A and a small amount of polymerization inhibitor; adding the obtained functional monomer B and a neutral monomer acrylamide into a certain amount of sodium chloride solution, and carrying out copolymerization reaction under the action of an initiator to obtain a zwitterionic copolymer; and carrying out a crosslinking reaction on the obtained zwitterionic copolymer and a crosslinking agent aqueous solution in a hydrochloric acid solution by co-heating to obtain the amphoteric micro-crosslinked polymer. Based on the reverse polyelectrolyte effect and the micro-crosslinking effect, the invention develops the amphoteric micro-crosslinking anti-settling auxiliary agent suitable for the high-salt system of the wet-milled concrete waste slurry, and has obvious beneficial effects compared with the prior art. |
