| titleOfInvention | A kind of preparation method of both sexes water-in-oil inverse emulsion |
| abstract | The invention discloses a kind of preparation method of both sexes water-in-oil inverse emulsion.Step, for non-ionic monomer, anionic monomer, cationic monomer, water quality stabilizer, molecular weight regulator to be added to the water respectively, to regulate PH, obtains aqueous phase A and B that two kinds of proportionings are different; Nonionic emulsifying agent is added in varsol and is configured to oil phase; Oil phase is divided into two portions, aqueous phase A and B is instilled in oil phase respectively, latex A and emulsion B is obtained through a step emulsification or multistep emulsification, latex A and emulsion B are used inert gas replacement deoxygenation respectively, emulsion B temperature is adjusted to kick off temperature, adds initiator, after 30-120min to be polymerized, start to drip latex A, continue reaction and make all conversion of monomers become polymkeric substance, reaction end obtains both sexes water-in-oil inverse emulsion product.The amphiprotic polyacrylamide that the present invention prepares has inhomogenous molecular structure, has high effective content, high molecular, low viscosity simultaneously, rapidly-soluble advantage. |
